Harin’Hala, Malaise, dry wash in forest, elev. 170 ft MG-42A-20 (CASC).</p><p>Differential diagnosis.</p><p>Tetractenion acaule is immediately distinguishable from all other Tetractenion species by its unique color combination of a red mesosoma and a mostly black metasoma; distinct keels are present on outer mesoscutal lobes, the notauli do not reach the scutellum; metasomal tergite I has a distinct medial compression in the dorso-ventral view, tergite II have distinct gastrocoeli, and tergites IV-VIII are dorso-posteriorly weakly sclerotized, appearing as large membranous white areas on the dorsal surface. Tetractenion acaule closely resembles T. ibayaensis as both species are similar in color, having largely fulvous bodies with a white face and the hind femur infuscate, whereas the remaining Tetractenion species are largely yellow in color with yellow hind femora. Tetractenion acaule can easily be distinguished from T. ibayaensis by having a white gena and weakly sclerotized metasomal tergites IV-VIII; the head is narrow, straight behind the eyes; a distinct carina is present on the pronotal collar; distinct keels are present on the outer mesoscutal lobes, with the notauli not reaching the scutellum; pits on the mesopleuron and propodeum are shallow; metasomal tergite I is distinctly dorso-medially compressed; gastrocoeli on tergite II are distinct; tergites IV-VIII are postero-dorsally weakly sclerotized and white; and tarsal claws on the hind leg are simple. In T. ibayaensis the gena is brown and tergites IV-VIII are strongly sclerotized; the head is rounded behind the eyes; with no more than a wrinkle present on the pronotal collar; the mesoscutal lobes are hardly present, the notauli reach the scutellum; pits on the mesopleuron and propodeum are deep; metasomal tergite I is stout and indistinctly dorso-ventrally compressed in the medial region; gastrocoeli on tergite II are indistinct; and tarsal claws on the hind legs are pectinate.</p><p>Description</p><p>(updated from Seyrig 1932).

Hind wing with Cu1 shorter than cu-a such that Cu2 arises above the middle of these combined veins. Legs very long; hind femur reaching beyond metasomal apex; length of tibia III plus tarsus III as long as body; spurs of tibia III longer than half metatarsal length; tarsal claws on hind leg simple.</p><p>Male hardly different: temples a bit less narrowed behind eyes, metasomal tergite II entirely black.</p><p>Distribution.</p><p>Madagascar.</p></div>	https://treatment.plazi.org/id/C9C92FC1C34557A2B7A51C7FA3FB8613	Public Domain	No known copyright restrictions apply.

Fig. 6</p><p>Type material.</p><p>Holotype ♂: Cameroon, Yaoundé, 1953, C.I.E. Coll. 15098. Pres. by Com. Inst. Ent., B. M. 1962-1. Exetastes sp. ♀ det. J. F. Perkins (NHMUK).</p><p>Differential diagnosis.</p><p>Tetractenion rosei is immediately distinguishable from other Tetractenion species by the reddish color of the head and pronotum in combination with a yellow body, completely yellow legs with venation on the wings also yellow. The head is not narrowed straight behind the eyes but rather rounded, distinguishing the species from T. acaule and T. pascali . The malar space nearly as long as the basal mandible width separates T. rosei from T. acaule, T. pseudolutea, and T. ibayaensis . Tetractenion acaule is the only other species besides T. rosei possessing a thickened and well-defined carina on the pronotal collar.</p><p>Pectinate hind tarsal claws separate the species from T. acaule and T. luteum . Sparse microtrichia on the wings distinguishes the species from T. luteum and T. pascali, and the pterostigma is yellow distinguishing the species from T. acaule and T. ibayaensis . Metasomal tergites II and III are longer than wide separating T. rosei from T. ibayaensis; and T. acaule, T. luteum, and T. ibayaensis, respectively.</p><p>Description.</p><p>Color: head and pronotum reddish, black area restricted to region of ocelli. Body, legs, antennae yellow. Wings with sparse microtrichia, venation yellow, pterostigma yellow.</p><p>Head rounded behind eyes; occiput deeply and angularly excavated, occipital carina strong, extending to lower gena at mandibular base; malar space nearly as long as basal mandibular width; eyes very large; face and clypeus moderately and evenly punctate on a shiny background; face with three lobes, tentorial pits deep; clypeus small, laterally convex with declivity, apically invaginated, clypeal edge convex; mandibular teeth triangular, lower tooth longer than upper tooth; antenna long, slender and apically tapered.</p><p>Mesosoma stout with a shiny background; mesopleuron moderately punctate, epicnemial carina ending at anterior edge of mesopleuron; pits on the mesopleuron and propodeum shallow; mesonotum moderately punctate; pronotum sparsely and finely punctate on a shiny background with a well-defined carina on collar; mesoscutum deeply punctate, mesoscutal lobes hardly present, notauli posteriorly meeting before reaching the scutellum; propodeum weakly convex, deeply punctate posteriorly confluently grading into transverse wrinkles, posterior transverse carina indistinct, lateral longitudinal carinae present, spiracle small and round.</p><p>Metasoma indistinctly punctate on a shiny background; tergite I more than twice as long as wide, tapered anteriorly, slight dorso-ventral depression in medial region, glymma present, spiracle in front of middle and protruding; tergites II and III longer than wide; gastrocoeli on tergite II indistinct; tergites IV-VIII higher than wide.</p><p>Hind wing with Cu1 shorter than cu-a such that Cu2 arises above the middle of these combined veins.

Sampling in other areas of the Afrotropical region has so far not produced any further specimens. The wings are inter-locked in such a way that a useful diagnostic character of the wings cannot be seen, i.e., whether the ramellus is present or not.</p></div>	https://treatment.plazi.org/id/6192521500945E63A78F936A6B4EA3CF	Public Domain	No known copyright restrictions apply.
