Perilypus virgulatus OPITZ nov.sp. ( Figs 11 , 185, 213, 277)

Holotype: ♂. Type locality: MEXICO, Oax , Hwy. 175, 15 mi. N. Pochutla, 800', 2 June 1983, C. W. & L. O’Brien & G. B. Marshall ( FSCA) . Paratypes: 2 specimens. Mexico, Estado de Guerrero, Acahuizotla , VI- 2006, 800 m, Canopy tree trap lure, P. japonica, collector not noted ( WOPC) ; Estado de Jalisco, 6 miles NE Barra de Navidad , 11-VIII-1982, C. W. & L. O’Brien, G. Wibmer ( WOPC) .

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 virgulatus specimens key out to P. distinctus EKIS, from which P. virgulatus specimens differ by showing a phallobasic lobe that is not uncinate.

D e s c r i p t i o n: Size: Length 5.5 mm; width 1.5 mm. Form: As in Fig. 277 . Color: Cranium castaneous; antenna brown; pronotum bicolorous, mostly flavotestaceous, arch with centrally located dark spot, collar narrowly black at middle; pterothorax and legs flavotestaceous; elytra bicolorous, mostly brown and with faintly visible bluish tinge, each disc with broad linear vitta. Head: Interocular depression shallow, crescentic; frontal umbo not prominent; cranium minutely punctate; antenna ( Fig. 11 ) moderately serrate, not densely setose, antennomeres gradually increasing in diameter from scape to antennomere 11; eyes finely facetted, eye narrower than frons (EW/FW 25/40). Thorax: Pronotum ( Fig. 185 ) transverse, very finely punctate; pronotal arch well defined; subapical depression well defined; side margins of pronotum proper strongly arcuate (PW/PL 90/80); elytra oblong rectangulate, pubescence short and profusely distributed throughout disc; disc punctures small and profusely distributed on disc, epipleural fold plane (EL/EW 245/65). Abdomen: Pygidium transverse / scutiform; aedeagus as in Fig. 213.

N a t u r a l H i s t o r y: The available specimens were collected during June and August, one by beating at 153 m.

D i s t r i b u t i o n: This species is known from southwestern México.

E t y m o l o g y: Thetrivialname, virgulatus, is a Latin adjective with a meaning of "stripes"; in reference to the vitta on the elytral disc.
