Description

Length of male 7.5–7.9 mm (female unknown). Crown with anterior margin parabolically rounded. Hind tibial rows PD, AD and AV with 18, 12 and 13 macrosetae, respectively. Style apophysis broadened from base to near apex, then strongly constricted, with posteroventral margin rounded and forming obtuse angle, distal extension with stem relatively long, apex broadened but distinctly less than half as wide as section just basad of constriction.

Remarks

Study of several specimens identified by J. W. Evans as “ Platyjassus viridis ” indicates that his concept of the species included several species that are similar in external appearance but readily distinguishable by the male genitalia. The species concept adopted here follows that of Linnavuori & Quartau (1975), who first illustrated the male genitalia of P. viridis , presumably based on study of Evansʼ type material. We were unable to locate the two male paratypes at MNHN. Other specimens identified by Evans in the BMNH collection do not bear paratype labels and either represent other species or their identities cannot be conirmed..
