Pararhaphidoglossa gibbiventris Giordani Soika, 1978

( Figs 9–11 , 15–17 )

Diagnosis. Male. As for the female, the presence of the median tubercle on S2 and the T2 convex only basally differs this species from congeners. The male is remarkably similar to the female, with more extensive yellow markings, and clypeus with narrower but deeper apical concavity.

Description. Male (hitherto unknown). Black, with yellow markings as folows: spot on mandible; clypeus except for the apical margin, whose black markings extends basally to the center; scape ventrally; F9 and 10 ventrally and F11 completely marked; thin line along margin of lower lobe of eye; eye emargination; interantennal spot; upper half of gena; wide band along base of pronotal carina that projects posteriorly on humeri; pronotum wih wide band on posterior margin and thin band on latero-posterior margin, including the pronotal lobe; scrobal spot; outer margin of tegula, darker anteriorly; metanotum; spots on coxae; outer surfaces of fore and mid femora; outer surfaces of tibiae; subapical bands from T1–6 and S1–6, briefly interrupted in T3 and S3–6. Ferruginous: base and apex of flagellum ventrally; T1, ventrally, on posterior half. Fore wing light brown, darker along the costal margin.

Clypeus approximately as long as wide, with free apical portion one-fourth of basal portion and apical margin, with two well-defined teeth separated by deep concavity of approximately one-sixth maximum width of clypeus. F11 falciform, with blunt tip as long as F9; posterior end of parategula little below level of remainder triangular parategula; propodeum concavity shallow, deepening apically; T1 filiform on basal-half, widening, triangle-like on apical half; T2 convex only on basal third, straight on remainder of sclerite and with long translucid apical lamella; S2 with median tubercle on basal-third. Fore wing length: 5,7 mm. Genitalia as in Figs (15–17), with aedeagus resembling that of P. pluviosa ( Zavattari, 1912) but with shortened basal plate.

Shallow and moderate macropunctation on clypeus; coarse and moderate macropunctation on frons, fading sparser and smaller on vertex; mesosoma rather densely and coarsely macropunctate; T1 with sparse macropunctures and dense micropunctures (same on sides of T2 and S2, but the macropunctation becomes denser near lateral margins; from T3 and S3 onward only dense micropunctation is present).

Dense, short and fulvous pilosity dorsally, becoming whitish ventrally. Longer and denser on metasomal segments, except T1.
