PHORTICA HANI SPECIES COMPLEX

Diagnosis: Arista with short dorsal branches (adf <1.0) and sparse micropubescence, lacking ventral branches ( Fig. 13 ); wing R 4+5 and M 1 veins nearly parallel; fifth sternite with dense setae, notched posteromedially ( Figs 6–12 ); cercus with two to three long, strong setae ventrally ( Figs 14 , 16 , 18 , 20 , 22 , 24 ); paramere with one spike-like process basally ( Figs 15 , 17 , 19 , 21 , 23 ); aedeagus nearly membranous, basally fused to gonopods, distally with sensilla ( Figs 15 , 17 , 19 , 21 , 23 , 25 ).

Description: Male. Head: eyes brown-red. Ocellar triangle black. Frons almost black, with grey pollinosity and a few thick setulae. Fronto-orbital plate brown. Pedicel brown. First flagellomere dark brown. Face almost black on upper part; brown on lower part; facial carina slightly developed. Clypeus yellow-brown medially, black laterally. Gena and postgena brown. Palpus yellow-brown. Occiput brown to black. Thorax: scutum almost black with dense grey pollinose pattern. Postpronotal lobe brownish yellow. Acrostichal setulae in about ten irregular rows. Scutellum black, submedially with silver-grey pollinosity and one pair of yellow patches. Wing: hyaline, slightly smoky, slightly darkened on R 2+3 and R 4+5 vein tips, r-m and dm-cu crossveins. Legs: all femuera brown to black except yellow at knee joints; tibiae yellow with two to three black rings. Forefemur with three rows of long setae on posterodorsal to posteroventral surface. Abdomen: tergites dark brown to dark brown except second yellow medially; second to fourth with narrow, white bands along posterior margins and yellow-brown patches anterolaterally; sixth brown.

Male terminalia: Epandrium not constricted middorsally, with pubescence and setae ( Figs 14 , 16 , 18 , 20 , 22 , 24 ). Surstylus elongated, with several small setae distally. Cercus separated from epandrium, elongated ventrally, entirely pubescent and setigerous. Membrane between epandrium and cercus pubescent. Tenth sternite separated into lateral lobes. Hypandrium arched, apically slightly sunken, with one pair of apodeme processes on anterior portion; posterior ends contiguous to posterolateral corners of gonopods and anteroventral corners of epandrium ( Figs 15 , 17 , 19 , 21 , 23 , 25 ). Paramere apically with two small, acute processes, subbasally broadened and pointed, basally contiguous to anterior portion of hypandrium and ventral branch of aedeagal apodeme Gonopods fused to each other, forming posteromedial plate in T-shape. Aedeagus developed, curved ventrad, with numerous spinules. Aedeagal apodeme thick.
