Xenopygina     Locustypicus: USA, Arizona, Pimo County, Tucson Mts.16 Km WTucson, 30.24°N, 111.13°W, Sonoradesert.  Holotype: Male,  9.–30.viii.1995, leg. S. Prchal, Malaise trap( PWMP).   Paratypes: 4 males, same data; 2 males, 15.–30.viii.1995, 1 male, 28.ix.–7.x.1995,  1 male,  30.iv.–16.v.1995, same location, leg. S. Prchal( PWMP, 1 malein PKHH, 1 malein MZH).  Description. Male. Head. Eye bridge 3 facets wide. 4th flagellomere with l/w-index of 2.0, haired as long as wide, brownish; neck rather long. Palpus 3-segmented, short; basal segment without deepened sensory area and one bristle only. Thorax. Brown; scutum haired brown. Wings pale; R1 = 2/3 R; c somewhat longer ½ w; y = x, bare; posterior veins bare. Haltere short, brownish. Legs yellowish-brown; tibial organ comb-like; middle and hind tibiae with long, but somewhat unequal spurs; claws toothless. Abdomen. Brown, haired brownish. Hypopygium brown, ventral base v-shaped. Gonocoxites longer than gonostylus, inner ventral margin haired short and densely. Gonostylus slender, weakly curved, without tooth but with 4 spines, two at the apex and two longer ones, positioned as pair subapically. Tegmen simple, somewhat trapezoid. Body size: 2.2 mm.   Comments. The species is well characterized by the two pairs of spines on gonostylus. It might however be mistaken with small species of  Bradysia, where spurs of the middle and hind tibiae are slightly different in length. Short palpus, short R1 and a small tibial organ support strongly its inclusion in the genus  Scatopsciarahowever. The species is similar to  Sc. subitumae.The species belongs to the  Sc. inesaegroup.   Distribution. USA( Arizona). *Ituma = white stone, Choktaw. 1291597572 1995-08-09 1995-08-30 1995-08-09 PWMP Km W & Male & S.
