(Fig. 269)

Lasiocolpus unicolor Poppius, 1909: 10 .

Diagnosis: Characterized by unicolored dorsum, small and flat calli on anterior lobe of pronotum, slightly sinuate edges of pronotum and presence of teeth on the midtibiae of male.

Redescription: Measurements, see Table VII. Male: Dorsal view: body oblong-oval. Antennae dark brown, base of exocorion and small dot on apex of cuneal fracture, paler. Pilosity semierect, sparse, not very long. Head: Eyes medium-sized; length of anteocular region subequal to eye length. Proportions of antennal segments (I:II:III:IV) 1: 3: 2.2: 2.3. Labium with segment II reaching midcoxae, III surpassing hind-coxae. Thorax: Pronotum slightly sinuate laterally, carina very marked on apical half; calli small, slightly protuberant, posterior margin slightly concave; collar thick; posterior lobe wrinkled (Fig. 292); hemelytra sinuate and not surpassing apex of abdomen (Fig. 295); membrana from tip of cuneus subequal in length to cuneus. Ventrally dark brown, unicolored. Pilosity short, decumbent, abundant. Midtibiae with teeth (Fig. 293), similar to foretibiae (Fig. 294). Abdomen: Hairs on dorsal surface of abdomen short, sparse. Genitalia: Pygophore (Fig. 296) with right paramere vestigial; left paramere more than half the width of pygophore and distally acute. Female: More robust than male, similarly colored. Head: Proportion of antennal segments (I:II:III:IV) 1: 3.2: 2.4: 2.4. Thorax: Pronotum with sides not sinuate, carina more marked than in male and calli more flattened.

Distribution: Bolivia, Brazil, Peru (Fig. 270).

Material examined: BRAZIL: ♂, Rio de Janeiro, Acc. Nº 2966. USNM; ♂, S. Catarina, 11 km. W. Fuck, 14-I- 1969, col. R. Stange. MACN; ♀ and ♂, Nova Teutonia, 17-XI-1952, F. Plaumann, J. C. Lutz collection. USNM .

Discussion: This species differs from L. sinuaticollis by its coloration, the presence of a row of teeth on internal margin of midtibiae, and by the male genitalia, with right paramere vestigial and left paramere more than half the width of pygophore and distally acute.
