E651AEECBB90CE9505C681599D37F4E6.taxon	diagnosis	Diagnosis. Tachysphex austriacus is the type species of the Tachysphex austriacus species subgroup. Tachysphex austriacus Kohl differs from all other species from the subgroup in the following combination of characters: ♂, ♀: gena narrow, conspicuously converging behind compound eyes; scutum and scutellum sparsely punctate, punctures well developed and usually up to 1.5 diameter apart (more than that in some specimens); ventral part of mesopleuron densely punctate, punctures relatively large and well developed in comparison to other species; trochanters densely punctate; ♂: ventral volsellar setae in one line; ♀: clypeal lip with distinct irregular median emargination; clypeal bevel forming slightly convex to flat plate, but the transition between the clypeal basomedian area and the bevel is not angulated; forebasitarsal rake pale, with four apical spines.	en	Straka, Jakub (2016): Tachysphexaustriacus Kohl, 1892 and T. pompiliformis (Panzer, 1804) (Hymenoptera, Crabronidae) are a complex of fourteen species in Europe and Turkey.

423D74D6204F4D9099A118AB42AF4607.taxon	diagnosis	Diagnosis. The female of Tachysphex hungaricus sp. n. resembles Tachysphex austriacus Kohl, Tachysphex prismaticus Straka and Tachysphex smissenae sp. n. and also Tachysphex jokischianus Panzer and Tachysphex punctipleuris sp. n. from the Tachysphex pompiliformis species subgroup in the sculptures and shape of the clypeus. This new species is the most similar to Tachysphex prismaticus. They share a characteristic form of the clypeus with nearly angulated transition between the basomedian area and a nearly flat bevel; vertex punctures without interspaces medially and at least one diameter apart laterally; very short setae of frons, vertex and scutum, about 0.3 x MOD; and uniform microareolate sculpture of propodeal dorsum with longitudinal ridges all over. Tachysphex hungaricus sp. n. differs from Tachysphex prismaticus in its much denser punctation all over the body; its scutum, trochanters and terga are not sparsely punctate. Females of the Tachysphex hungaricus thus resemble species of the Tachysphex pompiliformis species subgroup, but differ from them in having the characters, which were specified as synapomorphies with Tachysphex prismaticus in their comparison. It is the form of clypeus, sculpture of vertex and propodeum and length of vertex setae.	en	Straka, Jakub (2016): Tachysphexaustriacus Kohl, 1892 and T. pompiliformis (Panzer, 1804) (Hymenoptera, Crabronidae) are a complex of fourteen species in Europe and Turkey.

82979069CDC5641BE54373E69EFBE714.taxon	diagnosis	Diagnosis. Tachysphex prismaticus Straka resembles Tachysphex austriacus Kohl, Tachysphex hungaricus sp. n., and Tachysphex smissenae sp. n. in the shape of the clypeus and well developed punctures on the ventral part of the mesopleuron. It differs from the other species of the subgroup in the following character combination: ♂, ♀: mesopleuron rugose to densely punctate; venter of all trochanters with punctures several diameters apart, their interspaces unsculptured; all femora and tibiae black; ♂: volsella with large dorsal process; ventral volsellar setae in one line; ♀: clypeal lip with distinct irregular median emargination; clypeal bevel forming flat plate, separated from basomedian clypeal area by relatively sharp, more or less angulated transition; scutum and scutellum sparsely punctate, punctures up to two diameters apart at scutum center; forebasitarsal rake with four apical spines.	en	Straka, Jakub (2016): Tachysphexaustriacus Kohl, 1892 and T. pompiliformis (Panzer, 1804) (Hymenoptera, Crabronidae) are a complex of fourteen species in Europe and Turkey.

4E4C3B9D51C7EF3476D7E2E2F08B8055.taxon	diagnosis	Diagnosis. Tachysphex smissenae sp. n. resembles Tachysphex hungaricus sp. n. and Tachysphex prismaticus Straka in the shape of the clypeus: the limit between the basomedian area and the bevel appears angulated, although less so than in the other two species. This new species also has short setae (0.5 x MOD) on the frons, vertex and scutum, similar to the other two species. The sculpture of the propodeum, however, is coarser than in the other two species (it is areolate and not microareolate between longitudinal ridges), the sculptures of the whole body is coarser and denser and the vertex is normally sculptured, unlike Tachysphex hungaricus. The female differs from all other species of the Tachysphex austriacus and the Tachysphex pompiliformis subgroups by angulated shape of clypeus, sculpture of propodeum, short setae, gena robustly built, mesopleuron coarsely punctate, with relatively large and ventrally well developed punctures (similar to Tachysphex austriacus), terga densely punctate and posterior segments also coarsely punctate with apical depression of tergum V nearly impunctate and the pygidium relatively wide and shiny. The male has the forefemoral notch and the volsella typical for the subgroup (similar to Tachysphex prismaticus in shape), a conspicuously convex clypeus, which resembles that of the female (except the lip), densely and coarsely punctate terga and coarsely punctate mesopleuron, as in the female.	en	Straka, Jakub (2016): Tachysphexaustriacus Kohl, 1892 and T. pompiliformis (Panzer, 1804) (Hymenoptera, Crabronidae) are a complex of fourteen species in Europe and Turkey.

B815946CD179A646F8B721516D33970A.taxon	diagnosis	Diagnosis. Tachysphex bohemicus sp. n. is most similar to Tachysphex jokischianus in having nearly impunctate apex of tergum V and wide pigydium with shiny surface. It also resamble Tachysphex dimidiatus in the overall sparsely micropunctate metasoma, which makes the appearance of metasomal sculptures more shiny than in other compared species from the Tachysphex pompiliformis species subgroup. The apex of the male volsella of the new species is sparsely setose and may resemble volsella of males from the Tachysphex austriacus species subgroup. Both sexes of Tachysphex bohemicus sp. n. are easily recognizable by a slightly prominent supraantennal tubercles, which are separated by punctate area; the tubercle is distinctly punctate on the top and nearly at all sides. This character is unique in the Tachysphex pompiliformis species subgroup. Like Tachysphex jokischianus, the apical depression of tergum V is nearly impunctate medially, but the terga are finely and sparsely punctate and the pygidium is basally microsculptured; the metasoma thus resembles that of Tachysphex dimidiatus, except for the apical depressions of all terga, which are very sparsely punctate and well impressed. Tachysphex bohemicus sp. n. possess an unusual combination of characters: the propodeum lack longitudinal ridges dorsally and laterally, the female clypeus is distinctly arcuate at apex and uniformly convex dorsally, and the male forefemoral notch is black, positioned more anteriorly than in the other species of the subgroup and its proximal margin is rounded and elevated over the distal margin.	en	Straka, Jakub (2016): Tachysphexaustriacus Kohl, 1892 and T. pompiliformis (Panzer, 1804) (Hymenoptera, Crabronidae) are a complex of fourteen species in Europe and Turkey.

02CDECE3EC9B37B90BDE6097275BBF8E.taxon	diagnosis	Diagnosis. Tachysphex cretensis sp. n. is most similar to Tachysphex pompiliformis and Tachysphex opacus. They share a coarsely sculptured mesopleuron and the shape of the mandible is as in the latter species. The species is well recognizable by a coarsely sculptured dark body, four metasomal segments with silvery apical fasciae, the clypeal lip produced medially, the mandibular inner margin shallowly emarginated distally from the inner tooth, lacking any furrow, and a densely microsculptured forefemoral notch. The new species is probably endemic to the island of Crete, Greece.	en	Straka, Jakub (2016): Tachysphexaustriacus Kohl, 1892 and T. pompiliformis (Panzer, 1804) (Hymenoptera, Crabronidae) are a complex of fourteen species in Europe and Turkey.

F9A358BE0AC8806AD3F1828A49B8AC41.taxon	diagnosis	Diagnosis. Tachysphex dimidiatus (Panzer) is difficult to distinguish from Tachysphex jokischianus (Panzer), Tachysphex pompiliformis (Panzer) and Tachysphex punctipleuris sp. n. It is variable in most characters, and not a single character consistently differentiates it from the other species. It has the following combination of characters: ♀: The clypeus is markedly convex, the most elevated point is located between the clypeal midlength and the basal third. The clypeal bevel is distinctly triangular, it reaches the base of the clypeus in the middle, and separates the basomedian area into two parts; when the base of the clypeus is punctate, the punctures are larger and the distances between them are distinctly larger than on the lateral side of the basomedian area. The clypeal lip is arcuate or straight, without the medial anterior emargination even in fresh specimens. The vertex setae are semierect medially and nearly erect and slightly shorter than the MOD close to inner eye margin. The head is transversally oval in front view, with irregularly punctate frons. The gena is robust. The dorsolateral cuticular projection of the propodeal spiracle is slightly arcuate to nearly straight, with the apex reddish transparent. The posteromedial margin of the propodeal dorsum is elevated and produced between the marginal ridges, the marginal ridges directed ventromedially toward the groove on the posterior surface. The propodeal side is longitudinally ridged; ridges anteriorly inconspicuous or absent. The propodeal dorsum often has inconspicuous, irregular longitudinal ridges. The punctures of the mesopleuron are exceptionally variable but usually small and inconspicuous. The terga are sparsely punctate, the punctures are ill defined. Apical depressions of tergum V densely microsculptured with micropunctures, densely punctate latereally. The pygidium is of usual size and distinctly microsculptured in most specimens. ♂: The clypeus is convex, conspicuously elevated in the basal half, continuously declining apically, the top at the clypeal midlength or in the basal half of the clypeus. The clypeal bevel is well developed, shiny. The gena is robust. The supraclypeal area is flat, the supraantennal tubercles are connected, slightly elevated ventromedially. The mesopleuron is distinctly punctate laterally and ventrally, the punctures are ill defined. When the interspaces between the punctures are distinct, then they are microsculptured, slightly shiny to dull. The forefemoral notch is relatively shallow, as long as the distance that separates it from the forefemoral base, central part slightly elevated and lined by a ledge on the anterior as well as the posterior margin. The propodeal side is variable but without basal ridges in most specimens. The posteromedial margin of the propodeal dorsum is elevated and produced between marginal ridges, which are directed ventromedially toward the groove on the posterior surface. The terga are sparsely micropunctate with variable interspaces between punctures.	en	Straka, Jakub (2016): Tachysphexaustriacus Kohl, 1892 and T. pompiliformis (Panzer, 1804) (Hymenoptera, Crabronidae) are a complex of fourteen species in Europe and Turkey.

F49ED761FBD4D773D288FD73C6A5F47A.taxon	diagnosis	Diagnosis. Tachysphex ferrugineus Pulawski is easily recognizable by the body coloration, but in morphological characters and body sculpture it resembles Tachysphex dimidiatus (Panzer), Tachysphex jokischianus (Panzer), Tachysphex pompiliformis (Panzer) and Tachysphex punctipleuris sp. n. The species is similar to Tachysphex stysi Straka from central Asia in coloration, but Tachysphex stysi belongs to the Tachysphex austriacus species subgroup. Tachysphex ferrugineus Pulawski is largely light red colored. All tibiae, tarsi and nearly all metasoma, except basal part of terga IV-VI in males and IV-V in females, are light red. The species is similar to Tachysphex dimidiatus in body morphology and sculpture but differs in the following characters: ♀: Supraantennal tubercle distinctly elevated, but supraclypeal area nearly flat. Gena inconspicuously developed but not short. Pygidium densely punctate, all coarsely microsculptured, dull. ♂: Gena dorsally inconspicuous. Vertex finely and densely punctate, and postocellar impression shallow. Forefemoral notch large, usually longer than the space that separates it from forefemoral base.	en	Straka, Jakub (2016): Tachysphexaustriacus Kohl, 1892 and T. pompiliformis (Panzer, 1804) (Hymenoptera, Crabronidae) are a complex of fourteen species in Europe and Turkey.

F007470F60253633D39EFE04F6FCCE62.taxon	diagnosis	Diagnosis. Tachysphex jokischianus (Panzer) is difficult to distinguish from Tachysphex dimidiatus (Panzer), Tachysphex pompiliformis (Panzer) and Tachysphex punctipleuris sp. n. It is exceptionally variable in most characters, and no single character differentiates it from the other morphologically similar species. It can be recognized by the following combination of characters: supraclypeal area with distinctly microsculptured interspaces between punctures, usually appearing dull. Gena dorsally robustly built. Mesopleuron, including hypoepimeral area, finely sculptured, punctures in lower parts of mesopleuron distinct but small. Propodeal dorsum usually lacking longitudinal ridges, if present, then only basally. Dorsolateral cuticular projection of propodeal spiracle arcuate to semicircular, with dark apex. Posteromedial margin of propodeal dorsum elevated but not produced between the marginal ridges, marginal ridges positioned nearly horizontally above groove on posterior side. Wings only slightly infumated to pale. ♀: Apical depression of terga IV and V finely microsculptured and impunctate or nearly so, contrasting with coarsely and densely punctate central part of these terga, punctures of terga IV and V well developed. Pygidium often wide, with convex, shiny surface (but not always). Tergum III all red or red laterally and basally, with black area apicomedially. ♂: Surface of supraclypeal area concave, supraantennal tubercle distinctly elevated ventromedially. Forefemoral notch light red, large, its longitudinal diameter usually longer than the space separating it from forefemoral base. Propodeal side densely and finely ridged basally in most specimens. Terga densely micropunctate.	en	Straka, Jakub (2016): Tachysphexaustriacus Kohl, 1892 and T. pompiliformis (Panzer, 1804) (Hymenoptera, Crabronidae) are a complex of fourteen species in Europe and Turkey.

7129C7808D612A6F10DD1A396FBB4942.taxon	diagnosis	Diagnosis. Tachysphex nigripennis (Spinola) is easily recognizable from the other species of the Tachysphex pompiliformis and Tachysphex austriacus species subgroups. It is generally dark and coarsely punctate, and thus resembles Tachysphex opacus Morawitz and Tachysphex pompiliformis (Panzer). Tachysphex nigripennis (Spinola) is relatively well characterized species. It possesses an inconspicuous gena. The vertex is distinctly wider than long. The metasoma is coarsely punctate with densely micropunctate apical depressions. The mesopleuron is coarsely sculptured, rugose, or coarsely punctate, and the hypoepimeral area has more or less distinct longitudinal ridges. The metasoma has terga I-II dark red and a black sternum II. In females, the basomedian area of the clypeus is sparsely punctate; the pygidium is exceptionaly narrow, bright shiny and with inconspicuous lateral marginal carina. In males, the mandibular inner margin possesses one distinct rectangular tooth and a distinct furrow next to the tooth distally; the clypeal lip is distinctly arcuate, longest medially; the forefemoral notch is dark red but black in some specimens, with a shiny, nearly unsculptured surface; the dorsal process of volsella is larger than in species from the Tachysphex pompiliformis species subgroup.	en	Straka, Jakub (2016): Tachysphexaustriacus Kohl, 1892 and T. pompiliformis (Panzer, 1804) (Hymenoptera, Crabronidae) are a complex of fourteen species in Europe and Turkey.

Tachysphex nobilis sp. n. is most similar to Tachysphex bohemicus sp. n. and Tachysphex jokischianus (Panzer) in having fine and dense body sculptures and sparsely punctate apical margin of tergum V in female. Tachysphex nobilis sp. n. is a characteristic and relatively easily recognizable species. It is generally slender in body, finely, densely punctate throughout, and possess an insignificantly convex clypeus, with the bevel small in the female and nearly absent in the male. Both sexes also have the gena dorsally inconspicuous, converging behind the compound eyes. The lateral emargination of the clypeal lip in the female is round, not angulated. The propodeal dorsum in the male has a finely sculptured longitudinal area posteromedially, which appears slightly shinier than the adjacent parts of the propodeum.	en	Straka, Jakub (2016): Tachysphexaustriacus Kohl, 1892 and T. pompiliformis (Panzer, 1804) (Hymenoptera, Crabronidae) are a complex of fourteen species in Europe and Turkey.

Tachysphex opacus Morawitz is easily recognizable from other species of the Tachysphex pompiliformis and Tachysphex austriacus species subgroups. This species is generally dark and has coarsely sculptured mesopleuron and terga. Based on this characteristic, Tachysphex opacus resembles Tachysphex nigripennis (Spinola) and Tachysphex pompiliformis (Panzer). It differs from Tachysphex pompiliformis (Panzer) in having the gena inconspicuous and a sparsely punctate clypeal basomedian area. In the females, the metasoma has dark red terga I-II and a black sternum II, and the vertex is nearly as wide as long. In the males, the body is black, the mandibular inner margin is shallowly emarginated distally from inner tooth, with no furrow, the clypeal lip is nearly straight, the vertex is distinctly wider than long. In addition to the mentioned characters, the females of Tachysphex opacus Morawitz differ from Tachysphex nigripennis (Spinola) in having normal sized pygidium with microsculpture and lacking a bright shine. The males differ in having a forefemoral notch microsculptured, dull, and the dorsal process of the volsella narrow.	en	Straka, Jakub (2016): Tachysphexaustriacus Kohl, 1892 and T. pompiliformis (Panzer, 1804) (Hymenoptera, Crabronidae) are a complex of fourteen species in Europe and Turkey.

7B3C69ED67B90E678AD65D8E6FE16D57.taxon	diagnosis	Diagnosis. Tachysphex pompiliformis (Panzer) is difficult to distinguish from Tachysphex dimidiatus (Panzer), Tachysphex jokischianus (Panzer) and Tachysphex punctipleuris sp. n. It is exceptionally variable in most characters and no single character alone can differentiate it from morphologically similar species. This species is generally darker and more coarsely punctate than similar species. The metasoma is densely micropunctate, including apical depressions. The mesopleuron is coarsely sculptured, rugose, or coarsely punctate, and the hypoepimeral area has more or less distinct longitudinal ridges. In males, sternum II is often dark red to partly black, but tergum II is red; however, specimens with red metasomal segments I-III also occur. The terga are darker than in other species in some females, but this occurs less often. The forefemoral notch of the male is dark in most specimens. The gena is robust. The following combination of additional characters is also characteristic of this species: ♀: The clypeus is slightly convex, and the most elevated point is not well defined but located at about the clypeal midlength. The vertex setae are short and uniformly semierect both medially and laterally. The dorsolateral cuticular projection of the propodeal spiracle is arcuate to semicircular and usually dark. The propodeal dorsum and side are longitudinally ridged; the dorsum is coarsely sculptured, but the ridges are indistinct in some specimens. The forebasitarsal rake is reddish in fresh individuals, with two, well separated apical spines and one additional preapical spine. The wings are often but not always dark. ♂: The clypeus is coarsely punctate, the interspaces between the punctures large, approximately one diameter apart. The forefemoral notch is markedly carinated on the anterior and posterior margin. The volsella is dark, the dorsal process narrow, about as wide as the volsellar corpus basally.	en	Straka, Jakub (2016): Tachysphexaustriacus Kohl, 1892 and T. pompiliformis (Panzer, 1804) (Hymenoptera, Crabronidae) are a complex of fourteen species in Europe and Turkey.

0E0B1CC01E906D10925BE6B552342F02.taxon	diagnosis	Diagnosis. Tachysphex punctipleuris sp. n. is difficult to distinguish from Tachysphex dimidiatus (Panzer), Tachysphex jokischianus (Panzer) and Tachysphex pompiliformis (Panzer). It is exceptionally variable in most characters, and no single character alone can distinguish this species from the similar species. It possesses the following combination of characters: ♀: Clypeus slightly convex, the most elevated point not well defined, located approximately at clypeal midlength. Clypeal bevel variable, reaching the clypeal base in some specimens but well separated from it in others. Clypeal lip in fresh specimens sinuate, with ill-defined emargination medially. Vertex setae short, uniformly semierect medially as well as laterally. Postocellar impression well developed, deep, an open widely Y-shaped, or the posterior margin of the impression sinuous. Head nearly round, with uniformly, densely punctate frons. Gena robust. Punctures of mesopleuron variable but distinct and well defined in some specimens. Dorsolateral cuticular projection of propodeal spiracle arcuate to semicircular and usually all dark. Propodeal side uniformly longitudinally ridged, except in small specimens. Punctures of central part of tergum IV and V ill defined, interspaces between the punctures large, distinct, slightly shiny to shiny. Pygidium wide and shiny in most specimens, similar to Tachysphex jokischianus (Panzer). ♂: Clypeus slightly convex. Clypeal bevel large, densely punctate, interspaces between punctures small, punctures less than one diameter apart. Vertex approximately as wide as long. Gena robust. Supraclypeal area flat, supraantennal tubercle slightly elevated ventromedially. Mesopleuron laterally and ventrally distinctly punctate (punctures distinct also on hypoepimeral area in some specimens), punctures well defined, interspaces between the punctures distinct, slightly shiny to shiny on most parts. Forefemoral notch small, inconspicuously carinated, anterior carina distinct, black to dark red in coloration. Terga sparsely micropunctate, with variable interspaces between punctures. Volsella light brown, dorsal process basally wider than volsellar corpus.	en	Straka, Jakub (2016): Tachysphexaustriacus Kohl, 1892 and T. pompiliformis (Panzer, 1804) (Hymenoptera, Crabronidae) are a complex of fourteen species in Europe and Turkey.
