Lasiochilus (Semiotoscelis) duckei n. sp.

( Fig. 196 )

Diagnosis: Characterized by its short size, nearly 2 mm, relatively short interocular space and obovate shape.

Description: Measurements, see Table VI. Female: Dorsal view: Macropterous. Obovate, broad species. General coloration pale brown with head slightly darker, and dark punctures on hemelytra. Dorsal setae mediumsized to long, of same size throughout. Head: Shining, smooth, prolonged anteriorly by distance of 1.5x the length of one eye; eyes located near base; ocelli located above basal line of eyes; interocular space wide; antennal segment II linear, not longer than head. Antennal segments (I:II:III:IV) 1: 2.2: 2.3: 2.5. Thorax: Pronotum dull, calli elevated and slightly shiny, with lateral margins straight and carinate on apical 3/4; anterior and posterior angles square; posterior margin concave. Pronotal lobes rugose. Hemelytra with characteristic punctures with a seta emerging from each. Lateral margins with long, dense and slightly curved pilosity. Abdomen: Pilosity on dorsal surface, denser on outer margins than on central area. Genitalia: Parietovaginal gland greatly reduced ( Fig. 232 ); seventh sternite faintly punctured centrally ( Fig. 233 ).

Male: Unknown.

Distribution: Brazil. ( Fig. 200 ).

Material examined: Holotype BRAZIL: ♀ Amazonas, AM 010, km 26, Reserva Ducke, 1-XI-1977. USNM ; Paratype. ♀ Idem. (slide-mounted). MACN .

Etymology: The specific name refers to the site where this species has been collected.

Discussion: Despite the lack of males this is obviously a new species, distinguishable by its small size, wider body, carinate margins of pronotum, gratly reduced parietovaginal gland, and measurements.
