Psilochlorops Duda, 1930: 113

Type species: Psilochlorops clavitibia Duda (sub. mon. and sub. des., Duda, 1931: 167).

Diagnosis (emend). Body elongate, covered with relatively long pilosity. Frontal triangle shiny, gena with transversal rugosity, postgena swollen and pilose. Scutum flattened. Hind tibiae with a narrow, usually elongated tibial organ (except for a short tibial organ in P. clavitibia ).

Redescription. Body length, 3.5–6.5 mm. Body elongate, covered with relatively long pilosity. Frontal triangle shiny, usually lateral margins straight, with one row of interfrontals; frons dull; gena with transverse rugosity; postgena swollen and pilose; vibrissa usually small or indiscernible; eyes bare; palpus tiny. First flagellomere almost orbicular, yellow, with a brown macula at apex (except in P. clavitibia ); arista brown (except in P. paganelliae ), pubescent. Thorax elongate, narrow, smooth, shiny, finely pilose; scutum flattened dorsally, arched anteriorly, with a large mesal stripe of variable extent and a pair of lateral, more slender stripes; scutellum triangular, pilose, with distal and lateral scutellar bristles longer than scutellum (except P. nigrifemur ); hind tibia with a narrow tibial organ. Wing hyaline, costal vein ending slightly beyond apex of R4+5, R2+3 straight; R4+5 almost straight; M1+2 divergent from R4+5 and thinner beyond dm-cu insertion; CuA1 with flexure and also thinner beyond dm-cu insertion; dm-cu and r-m separated from each other by more than their length. Male postabdomen with mesolobus (fused cerci) almost square, bilobed, rectangular or weakly sclerotized; surstylus variable in shape, fused to epandrium or not; hypandrium broad, with apical extensions directed ventrally; phallapodeme short; gonites variable.
