( Figure 4 )

Diagnosis. This species is readily distinguishable from others in the genus by the short crown with evenly rounded anterior margin and by the elongate, arched aedeagus.

Description. Length of male 3.5 mm. Color pale stramineous, frontoclypeus, basolateral triangles of mesonotum and median area of mesonotum and scutellum pale ochraceous. Crown in dorsal view ( Fig. 4B ) with anterior margin evenly rounded, subparallel to posterior margin, median length less than width between eyes. Forewing with second apical cell petiolate ( Fig. 4A ).

Male 2S apodemes ( Fig. 4D ) short and rounded. Pygofer lobe ( Fig. 4E ) with small but distinct sclerotized rounded tooth posteroventrally. Subgenital plate ( Fig. 4G ) moderately long with 4-5 macrosetae, apex oblique. Style preapical lobe rounded, apophysis footlike apically with short toe and rounded heel ( Fig. 4G ). Aedeagal shaft elongate, slender, evenly arched in lateral view ( Fig. 4H ) with preapical processes short and well separated from apex, apical processes relatively long, acuminate and extended ventrobasad relative to shaft apex. Gonopore preapical on posterior surface adjacent to tips of distal processes ( Fig. 4G ).

Etymology. The species name is a Latinized adjective referring to the relatively short head.
