Type material examined.
Holotype (female). "SURINAME: Sipaliwini District, 2°28'37.1994"N, 55°37'45.876"W, 275m/ Camp 1: Upper Palemeu,/ 10-16.iii.2012, leg. A.E.Z. Short/ Flight Intercept Trap/ SR12-0310-TN1" (SEMC; voucher SLE456). Paratype (female): "FRENCH GUIANA, Cayenne, 33.5 km S and 8.4 km NW of Hwy N2 on Hwy D5, 30 m 4°48'18"N, 52°28'41"W, 29 MAY - 9 JUN 1997; J. Ashe, R. Brooks, FG1AB97 171 ex: flight intercept trap" // "Barcode/ SM0102412/ KUNHM-ENT" (SEMC, 1).
Differential diagnosis.
Quadriops acroreius is very similar to Q. dentatus , both species being moderately convex (as opposed to dorsally flattened) and the serial punctures of the elytra are randomly and uniformly distributed, not aligned to form well-defined longitudinal rows. It can be easily distinguished by the shape of the elevation of the mesoventrite, which is a wide, transverse, straight carina (as opposed to a toothlike projection as in Q. dentatus ); in addition, the surface of head and clypeus between punctures is smooth (as opposed to reticulated).
Description.
Body length 1.9-2.0 mm, width 1.2-1.3 mm. Body elongate oval, moderately convex. General coloration uniform dark brown. Surface of pronotum and elytra, smooth (as opposed to reticulated between punctures), only slightly reticulated on head and clypeus. Elevation of mesoventrite forming a wide, transverse, straight, blunt, strongly raised carina. Metaventrite with a postero median semi triangular glabrous area. Elytra with randomly and uniformly distributed punctures, not aligned into striae; surface of pseudepipleura anteriorly reticulated, posteriorly smooth. Metafemora with basal 1/8 covered by pubescence.
Etymology.
Named from the Greek “akroreia”, meaning mountain ridge (Brown 1956), in reference to the pronounced transverse carina on the elevation of the mesoventrite.
Distribution.
Suriname; French Guiana. See Fig. 9B.
Biology.
The male of the species is not known. Specimens were collected at flight intercept traps.
