Camptocerus satyrus Smith and Cognato , new species

(Fig. 34, 64)

Type Material. Holotype: male, BRAZIL: Rondônia: 62 km SW Ariquemes , nr Fzda. Rancho Grande, ex. MV & UV lights, 4-16.xi.1997 (J.E. Eger) ( FSCA).

Diagnosis. The male is distinguished by its large size, by the convex second sternite, by the declivital interstriae bearing 2-3 rows of overlapping, pale, yellow, recumbent scales, which become uni- and biseriate at the apex, by the lateral epistomal margins bearing a dense brush of setae extending halfway from the epistoma to the level of scape, by the frontal excavation with 1-2 setae lateral to the median line, and by the 25-30 setae on the lateral and dorsal margins.

Description (male). 4.0 mm long (n = 1); 1.7 times as long as wide. Color uniformly red-orange (holotype may be teneral).

Epistoma strongly excavated, excavated from epistoma to anterodorsal margin of the eyes, excavation bordering the ocular margin; expanded to greater than quarter length of head; surface shagreened; single seta lateral to median line; each lateral margin with a sub-acute vertical costa and bearing a dense brush of setae extending halfway on the lateral margin from the epistoma to the level of scape insertion; apical margin armed with a short, rectangular carina; basal margin tumid above scape insertion (Fig. 2b). Frons strongly excavated from epistoma to anterodorsal margin of the eyes, excavation bordering the ocular margin; surface shagreened; bearing 1-2 rows of erect golden setae lateral to the median line, surface moderately covered; lateral and dorsal margins bearing 25-30 setae. Antennal scape elongate, expanded distally, bearing 5 rows of setae on distal two-thirds, those length of scape; segments 2-7 of funicle bearing setae on ventral margin equal to 1.5 times length of funicle; setae on dorsal margin, less than length of 5 segments; setae on ventral margin twice as thick as those on dorsal margin; anterior face of the club setose, with a partial septum.

Apical pronotal margin broadly rounded (Fig. 5a), area between eyes lined with scales; surface minutely granulate-punctate, with minute, shallow punctures; anterior fifth bearing 2-3 rows of yellowbrown setae; a row of yellow setae above lateral carinae; base weakly recurved (Fig. 8b); carina on lateral margin type C (Fig. 7c).

Scutellum shape type B ( Fig. 12b ).

Elytral sides parallel, narrowing to a smooth apex; base never tumid from interstriae 7-9. Disk with shallow rugosities extending from striae 1 to interstriae 4 and from the base to just beyond the scutellum, the remaining elytral surface minutely granulate. Discal interstriae bearing 2-3 rows of overlapping, pale, yellow recumbent scales, declivital interstriae bearing uni- and biseriate rows at the apex. Tenth interstriae with a carina encompassing elytra. Metepisternum shape type C ( Fig. 9c ); setae palmately divided into 4 or more filaments. Mesosternum shape type E ( Fig. 10e ). Second sternite convex.

Male genitalia. Median lobe strongly arcuate, lateral and apical margins with more sclerotization, apex broad, apical orifice membranous on apical quarter, lateral folds on basal half contiguous. Median struts one-fifth of body length. Internal sac central area membranous bearing setae just above seminal valve. Seminal valve heavily sclerotized, arising just above median struts, narrow on basal half, gradually apically expanding to width of median lobe, flattened medially; distal margin crenulated, folded on lateral margins of apical third, medial region with 4 tuberculate and serrate projections ( Fig. 64). Tegmen semi-circular, ventral side elongated proximally. Spicule nearly longer then aedeagus, sickle-shaped.
