Allaporus toltecus

Allaporus toltecus Evans
AUaporus toltecus Evans, 1953, Jour. Kansas Ent. Soc, 26: 31 [Type: 8, Mexico: Mexico: Teotihuacan Pyramids, 7500 feet, 15 June 1951 This species was described from a single male. I have since collected a female which undoubtedly belongs to the same species. Both sexes are readily recognized by the bluish pubescence and the abundant dark setae.
Plesiallotype. — 5, Mexico: Morelos: 4 mi. E Cuernavaca, 6000 feet, 25 June 1959 (HEE) [MCZJ.
Description of plesiallotype female. — Length 8.8 mm.; fore wing 7 mm. Body and legs black, rendered by the pubescence a rich, dark bluish; mandibles mostly rufous; fore wings wholly fuscous, violaceous; hind wings subhyaline basally, somewhat infuscated apically. Temples, propleura, and front coxae with abundant dark setae; front, vertex, thoracic dorsum and pleura, propodeum, and middle and hind coxae sparsely short-setose; front femora with a few short setae; abdomen sparsely setose ventrally and apically. Mandibles relatively slender, unmodified, with two small teeth on the inner margin. Clypeus 2.5 X as wide as high, apex subtruncate, with a narrowly elevated, shining margin. Head 1.1 X as wide as high; MID .66 X TFD, 1.12 X LID, .90 X HE; UID .87 X LID. POL:OOL= 13: 10; distance from posterior ocelli to vertex crest .7 X POL. First four antennal segments in a ratio of about 26:6:14:17, segment three twice as long as thick, .3 X UID. Vertex passing nearly straight across between tops of eyes, not at all sharply margined; spatium frontale prominent, perpendicularly declivous between antennal sockets. Pro
notal disc .65 X as long as wide, 1.5 X as long as mesoscutum. Propodeum relatively short and with an oblique, nearly flat declivity, without a trace of rugae. Front femora not incrassate, measuring 3 X as long as wide; longer spur of hind tibia .55 X as long as basitarsus. Fore wing with basal vein arising slightly basad of transverse median vein, its lower section strongly arched; SMC2 1.6 X as wide as high, narrowed by .6 above. Hind wing with first abscissa of cubitus long and strongly arched before junction with intercubital vein, first abscissa of radial vein also relatively long and arcuate before meeting intercubital vein. Apex of abdomen moderately compressed.
Male. — Length 6 mm. Black; wings lightly, rather evenly infuscated. Pubescence in large part reflecting dark bluish, on the lower head, sides of the thorax, coxae, and posterior slope of the propodeum silvery. Body with dark erect setae distributed much as in female. Front broad, eyes divergent above, UID 1.2 X LID; POL and OOL subequal. Third antennal segment 1.2 X as long as thick. Wings about as in female. SGP moderately broad; genitalia with the parameres considerably shorter than digiti, the latter with very small setae.
