Description.
Body short elliptic, moderately convex. Mandibles, head, scutellum, elytra and ventral surfaces, including coxae dark chocolate brown; pronotum, antennal calli and median line on frons blackish; labrum, legs and antennae testaceous, with infuscate base of tibiae and apical antennomeres, except apex of eleventh antennomere; palpi ochre. Length: 5.5 mm; width: 3.1 mm (range of male specimens: 4.8–5.5 mm long, 2.9–3.1 mm wide).
Frons with few tiny punctures near middle impression and supraocular sulci prolonged medially to slightly over middle of dorsal edge of supraantennal calli; clypeus with few tiny punctures basally and anterior border moderately emarginate. Eyes moderately big, separate on frons by 2.1 × their transverse diameter. Relative proportions of antennomeres: 1.8-1.0 - 1.6 - 1.9 - 2.4 - 2.1 - 2.4 - 2.2 - 2.2 - 2.2 - 2.7. Surface of pronotum with scattered small, slightly aciculate punctures on disc and lateral declivities. Prosternal process nearly as wide as transverse diameter of procoxae. Elytra about 1.2 × as long as ensemble width at base, widest behind weakly callous humeri; surface finely alutaceous, shinier than pronotum, with moderate punctures, smaller than intervals, rather confused anteriorly on disc. Protibiae (inset in Fig. 6 c View Figure 6 ) as long as profemur, weakly curved and gradually widened before strongly enlarged ventral apical quarter, with sharp external keels, ventral keel with wide preapical weak emargination, rows of recumbent setae dorsally and relatively dense recumbent setae ventrally; mesotibiae slightly shorter than mesofemora, slightly bent ventrally and gradually widening before strong bent and enlargement at apical quarter, with rather sharp anterior ventral keel; metatibiae as long as metafemora, straight and gradually widened towards apex, more markedly in apical quarter; pro- and mesobasitarsomeres enlarged, wider than and as wide as third tarsomere in pro- and mesotarsi, respectively, and narrower in metatarsi, shorter than second and third tarsomeres combined in all tarsi. Median apodeme of first abdominal ventrite about half as long as ventrite, subtrapezoidal, narrower than mesosternal process; all ventrites with fine microreticulation, sparse fine punctures and long fine, posteriorly adpressed pale yellow setae. Penis (Fig. 7 j View Figure 7 ) slender, regularly curved ventrally, with sides slightly concave in ventral view, nearly as wide preapically as wide at base; apex elongate oval, round distally with short projecting blunt tip; gonopore elongate elliptical, with distal end separated from apex of penis by distance shorter than maximum width of gonopore; dorsal flap subrectangular, longer than wide, covering about basal half of gonopore. — Females. Females also have punctured frons and clypeus. Spermatheca (Fig. 1 n View Figure 1 ) with cornu shorter than nodulus, bent more or less at right angle relative to nodulus; nodulus bulbous basally, with short protruding insertion of spermathecal gland submedially, opposite to cornu; spermathecal duct thin, inserted laterally near base of nodulus, oriented opposite to cornu and recurved parallel and slightly longer than nodulus before gradual enlargement with one complete, elongate coil.
Diagnosis.
Among species with dark bicolour dorsum and testaceous appendages and wide prosternal process, as wide or wider than procoxae, C. tibialis sp. nov. has the shortest proportions, looking quite compact, and males show a very special conformation of front and middle tibiae allowing to recognize it from any other species of Cazeresia at once. Size (<6.0 mm), shorter proportions (<1.75) and male tibiae are particularly useful traits to distinguish it from sympatric C. holosericea sp. nov.
Derivatio nominis.
The species name focuses the attention on the peculiar shape of anterior and middle tibiae of males by using the Latin adjective (f.), tībiālis, applied to something of or pertaining to the tibia.
Distribution.
The specimens available for this species come from a single locality at moderate elevation (620 m a. s. l.) close to the northeastern coast of Grande Terre, north of the Central Massif (Fig. 8 e View Figure 8 ).
