(Fig. 234)

Lasiocolpus biguttatus Poppius, 1909: 10 .

Diagnosis: Small, body oblong, head short compared to the remainder of the species in the genus. Characterized by its coloration, external morphology, the peculiar shape of the paramere and geographical distribution.

Redescription: Measurements, see Table VII. Male: Dorsal aspect: body oblong; general coloration dark brown to black; basal third of corion with reduced spot at level of cuneal fracture; antennae pale whitish. Pilosity semierect, long, not very dense. Head: Broad, eyes large; anteocular region shorter than eye length; antennal segments (I:II:III:IV) 1: 3.1: 2.7: 2.7. Labial segment II reaching midcoxae; III surpassing hindcoxae. Thorax: Pronotum slightly sinuate laterally, slightly carinate on apical half; posterior margin slightly concave; collar broad, straight; calli large and protuberant; posterior lobe slightly punctured, wrinkled. Hemelytra with sinuate sides, surpassing apex of abdomen; cuneus basally longer than wide; membrana from tip of distal region of cuneus as long as cuneus. Ventrally unicolorous, dark brown; pilosity short, decumbent, not dense. Foretibiae with row of teeth; pad small (Fig. 241); midtibiae without line of teeth. Abdomen: Hairs on dorsal surface of abdomen short and denser at outer margins; central area with some very long hairs directed backward. Without a grouping of copulatory teeth on sixth abdominal segment. Genitalia: Right paramere absent; left paramere long (Fig. 243), more than half the width of pygophore (Fig. 242), distally rounded. Female: unknown.

Distribution.— Brazil. (Fig. 240).

Material examined.— BRAZIL: ♂, Am., P. Laranjeiras, 8/14-VII-81, Arias col. INPA ; ♂, Amazonas, AM 010 km 26, reserva Ducke, 18-VII-1978, armadilha de malaise, INPA .

Discussion: Differs from L. maesi n. sp by having a longer left paramere and different coloration of clavus and corion. This is the only known species of this genus with an Amazonian distribution. The remainder are circum-Caribbean or southern subtropical-South American.
