Perilypus alpinus OPITZ nov.sp. ( Figs 13 , 186, 209, 271)

Holotype: ♂. Type locality: Mexico, Chiapas, Cañon Sumidero , 0-12.2 km N Park Entrance, TDF. A second label reads; 18-vi-2016, Beating, J. Rifkind, E. Martinez, colls. ( CSCA).

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 alpinus specimen keys out to P. caliculus EKIS, from which Perilypus alpinus differs by showing a serrated tegminal dome, which is not present in P. caliculus specimens.

D e s c r i p t i o n: Size: Length 6.0 mm; width 2.0 mm. Form: As in Fig. 271 . Color: Cranium bicolorous, lower frons and clypeus yellow, upper frons, and middle epicranium black, sides of epicranium yellow, cranial venter yellow; antenna black; pronotum broadly yellow at sides, with black discal marking that has central yellow spot; pterothorax dark brown; elytra black; legs bicolorous, femora mostly flavotestaceous, infuscated in distal 1/2, tibiae and tarsi black; abdomen dark brown. Head: Interocular depression shallow, crescentic; frontal umbo not prominent; cranium minutely punctate; antenna ( Fig. 13 ) moderately serrate, not densely setose, antennomeres gradually increasing in diameter from scape to antennomere 11; eyes finely facetted, eye narrower than frons (EW/FW 25/38). Thorax: Pronotum ( Fig. 186 ) transverse, very finely punctate; pronotal arch well defined; subapical depression well defined; side margins of pronotum proper strongly arcuate (PW/PL 90/78); elytra oblong rectangulate, pubescence short and profusely distributed throughout disc; disc punctures small and profusely distributed on disc, epipleural fold plane (EL/EW 240/65). Abdomen: Pygidium transverse / scutiform; aedeagus as in Fig. 209.

N a t u r a l H i s t o r y: The available specimen was collected during June, by beating.

D i s t r i b u t i o n: This species is known from México. E t y m o l o g y: Thetrivialname, alpinus, is a Latin name with a meaning of "high mountain"; in reference to the type locality.
