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.
