Anoplius (Pompilinus) texanus (Dreisbach)
Pompilinus texanus Dreisbach, 1949, Ent. Amer., (n.s.)29 14-15 [Type: $, Texas: Lee Co., May 1907 (Birkman) (MCZ, no. 29, 324)].— Dreisbach, 1952, Amer. Midi. Nat., 48: 145, 159.
Anoplius (Pompilinus) texanus Evans, 1951, Trans. Amer. Ent. Soc, 76: 290291. — Evans, 1956, Ann. Ent. Soc. Amer., 49: 174 (Morelos, Mexico ) .
The female of this species has not previously been described. The species occurs widely in Mexico but appears to be uncommon.
Female. — Length 7-10 mm. Black; pubescence wholly dark, reflecting shades of deep blue in certain lights. Pronotum with a few short setae, propodeum without setae. Clypeus 2.4-2.5 X as wide as high, its apical margin truncate. Head 1.10-1.13 X as wide as high; vertex very slightly, arcuately elevated above eye tops (much less so than in subcylindricus) . Front of moderate breadth, MID .58-.61 X TFD; UID .85-.90 X LID; ocelli in a broad triangle, POL:OOL = 6:5. First four antennal segments in a ratio of about 21:7:26:22, segment three equal to from .68 to .75 X UID. Posterior margin of pronotum with a distinct median angulation. Propodeum rather short, with an oblique, nearly flat declivity. Front basitarsus with three comb-spines, the spines about as long as the width of the tarsus.
Male. — Length 5.5-8 mm. Black; pubescence extensively silvery, tending to be rather coarse on the propodeal slope. Body without conspicuous erect hairs except for a few on the head and prothorax, also a dense brush of hairs of moderate length on S4. Clypeus 2.2-2.4 X as wide as high. MID .59-.60 X TFD; UID very slightly greater than LID; POL very slightly greater than OOL. Third antennal segment about 2.2-2.4 X as long as wide, about as long as fourth segment. Pronotum broadly angulate behind. SGP unusually slender, somewhat parallel-sided, covered with short, suberect hairs. Genitalia with the parameres distinctly wider than in subcylindricus and the inner margin of the digiti more sinuate than in that species, but the genitalia otherwise very similar (see figs. 128 and 155 in Evans, 1951; also fig. 37 in Dreisbach, 1949, and fig. 13 in Dreisbach, 1952).
Distribution. — Louisiana and Texas to Morelos and to Yucatan. See Evans, 1951, for U. S. records. (Map 54.)
