Perilypus apunctus OPITZ nov.sp. ( Figs 10 View Figs 1-27 , 195, 210, 272)

Holotype: ♂. Type locality: 10 mi. NW Eagle Pass , TEXAS, VIII-8-59, R. B. Selander & J. C. Schaffner, light ( TAMU).

D i a g n o s i s: The genus Perilypus SPINOLA was revised in 1977 (EKIS 1977). This work included a key to species. The available Perilypus apunctus specimen keys out to P. distinctus EKIS, from which the P. apunctus specimen differs by showing a phallobasic lobe that is not uncinate. The aedeagus of the P. apunctus specimen is also similar to those of P. virgulatus , but the phallobasic lobes are significantly more elongate in the P. apunctus specimen.

D e s c r i p t i o n: Size: Length 9.0 mm; width 2.5 mm. Form: As in Fig. 272 View Figs 270-273 . Color: Cranium, prothorax, and mesosternum yellow; antenna black, except scape yellow; metathorax black; elytra dull violaceous; legs bicolorous, femora yellow, infuscated apically, tibiae and tarsi black. Head: Interocular depression shallow, crescentic; frontal umbo not prominent; cranium minutely punctate; antenna ( Fig. 10 View Figs 1-27 ) serrate, not densely setose, antennomeres gradually increasing in diameter from scape to antennomere 11; eyes finely facetted, eye narrower than frons (EW/FW 30/40). Thorax: Pronotum ( Fig. 95 View Figs 92-100 ) transverse, very finely punctate; pronotal arch well defined; subapical depression well defined; side margins of pronotum proper strongly arcuate (PW/PL 105/90); elytra oblong rectangulate, pubescence short and profusely distributed throughout disc; disc punctures small and profusely distributed on disc, epipleural fold plane (EL/EW 340/85). Abdomen: Pygidium transverse / scutiform; aedeagus as in Fig. 210. View Figs 207-212

N a t u r a l H i s t o r y: The available specimen was collected during August, at light.

D i s t r i b u t i o n: This species is known from the United States of America, Texas.

E t y m o l o g y: The trivial name, apunctus, is a Latin compound name that stems from the prefix – a (= without) and the noun punctum (= dot); in reference to the lack of a dark spot on the pronotal disc, very characteristic of many males of Perilypus species.
