Clypeus usually sparsely punctate in its upper part and impunctate in lower part.
Face, frons, mesoscutum, mesopleuron and dorsolateral area of propodeum often impunctate or with fine and sparse punctures 5
moesta in respect of its small size as well as densely granulate, impunctate head and mesosoma, but differs from these and other Afrotropical species of the genus because of the very short basal keel of propodeum, weak foveate groove of mesopleuron and hind wing with nervellus strongly reclivous.
Head and mesosoma dark reddish brown, predominantly finely granulate and impunctate, but with shining, almost smooth temple and fine indistinct punctures on mesopleuron.
55x as long as apical area; apical area flat, rounded anteriorly, impunctate, granulate, with fine transverse -wrinkles; apical longitudinal carinae strong, reaching transverse carina.
The similarity of Tyronella to impunctate
orthide brachiopods such as Toxorthis (Temple 1968) has been discussed by Rong (1984).
Head: Slightly less than two rimes length, interocular width subequal to two rimes dorsal width of an eye; posterior area behind eyes narrowed, forming a short, indistinct neck in males; impunctate, shiny, frons with a few transverse rows of indistinct, dull spots; set with a few scattered, whitish scalelike setae on vertex, frons, and ventral surface.
TEXTURE, STRUCTURE, AND VESTITURE: Head: Shiny, impunctate, frons with four or five transverse rows of indistinct, small, fine, shiny, impressed spots; eyes somewhat coarsely faceted; with scattered, whitish scalelike setae especially on vertex and undersurface, intermixed with pale, semierect, simple setae on frons and clypeus.
TEXTURE: Impunctate, polished, not shagreened; forewings coriaceous, more so along inner claval margin.
TEXTURE: Impunctate, polished, callosite region of pronotum and corium anteriad to orangish brown marking, shagreened.
TEXTURE: Impunctate, polished, pronotum and corium shagreened.
Gastral tergum I without punctures; terga II-IV with dense, fine punctures medially and posteriorly, impunctate
basally; tergum V with dense, fine punctures; pygidial plate elongate triangle, with dense, coarse punctures, and with long, yellow bristles (Fig.
