Etymology

The species name refers to the nearly symmetrical aedeagus.

Material examined

Holotype

MADAGASCAR • ♂; “Andobo, 190 m, foret Antsingy det Antsalova, II-57 P. Griv.; INSTITUT SCIENTIFIQUE MADAGASCAR ”; MNHN.

Description

Length of male 7.8 mm (female unknown). Pale ochraceous throughout. Crown shorter than pronotum, anteror margin parabolically produced. Hind tibial rows PD, AD and AV with 18, 13 and ~12 macrosetae, respectively. Male pygofer lobe elongate, apex obliquely truncate. Style apophysis robust, broadened and straight through most of length, densely denticulate ventrally, apex abruptly but slightly curved dorsad and terminating in acute point. Aedeagus with atrium V-shaped in posterior view, shaft arising dorsally, relatively short, tubular, evenly curved dorsad, with pair of short, recurved preapical lateral processes just basad of apical gonopore; basal process arising from ventral end of atrium well separated from shaft, nearly symmetrical, sharply bent dorsad near base, thence nearly straight, slightly broadened preapically in ventral view, then gradually tapered to acuminate apex, slightly surpassing shaft.

Remarks

According to the previously attached determination label, the holotype designated here was identified as “ Platyjassus viridis ” by J.W. Evans in 1958, but its genitalia do not match those of the specimen identified as that species and illustrated by Linnavuori & Quartau (1975). Study of other material identified by Evans indicates that his concept of P. viridis included several species that are similar in external appearance but readily distinguishable by the male genitalia.
