Aegialia amplipunctata Gordon & Cartwright 1988

Aegialia (Aegialia) amplipunctata

DESCRIPTION—Holotype: Male, length 360 mm, greatest width 180 mm Form elongate oval, convex, widest at middle of elytron (Figure 20) Color reddish brown Head densely rugose, lacking punctations, rugae pronounced medially on clypeofrontal suture; clypeal apex barely perceptibly emarginate, gena definitely produced Pronotal surface shiny, feebly alutaceous, punctations extremely coarse on disc, slightly smaller toward lateral margin, separated by less than to twice a diameter; base with strongly impressed marginal line Elytron with interval strongly convex with fine, irregularly scattered punctations, stria deeply impressed, coarsely punctate, punctations separated by a diameter or slightly less Metasternum smooth, impunctate medially, alutaceous, impunctate laterally Functional wings present Middle tibia robust, wide, with some surface denticles, single transverse carina in apical nearly complete, apical spurs slender, inner spur as long as first 3 tarsal segments, outer spur as long as first 2 tarsal segments; hindfemur with apical flange slightly produced, inner angle rounded; hindtibia as described for middle tibia except transverse carina complete, apical spurs somewhat spatulate, subequal in length Male genitalia as in Figure 52

TYPE MATERIAL—Holotype: “North Dakota, Ransom Co, 7-V-1962, Robert Gordon” (USNM)

REMARKS—The holotype is the only specimen we have seen The overall appearance of A amplipunctata is most like that of A latispina and A opifex, but A amplipunctata has coarser pronotal punctations, a complete transverse carina on the hindtibia, and the clypeus is rugose rather than granulate The armature of the male internal sac of A amplipunctata is also unlike that of any described species of Aegialia, sensu stricto

ETYMOLOGY—The specific name is from the Latin and refers to the large pronotal punctations
