Camptocerus latipilis Schedl

( Fig. 30 – 31 , 61)

Camptocerus latipilis Schedl 1973:166 . Holotype: male, BRAZIL: Pará : Benfica: Ananindeua (MZSP).

Diagnosis. The male is distinguished from that of C. petrovi by the smaller size, by the black color, by the strongly convex and protuberant second sternite, with the height of declivity behind much less than length of sternite 3, by the lateral epistomal margins bearing a dense brush of setae extending halfway from the epistoma to the level of scape insertion and by the glabrous frontal excavation with 10-12 setae on the lateral and dorsal margins.

The female can be distinguished from that of C. coccoformus by the more strongly impressed medial area of the frons and the black head and pronotum.

Redescription (male). 2.7-3.3 mm long (mean = 3.2 mm; n = 6); 1.7- 1.9 times as long as wide. Color uniformly black.

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; bearing a dense brush of setae extending halfway on the lateral margin from the epistoma to the level of scape insertion; each lateral margin with a sub-acute vertical costa; 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 bor-

dering the ocular margin; surface shagreened, gla-

brous, with 10-12 setae on lateral and dorsal mar-

gins. Antennal scape elongate, expanded distally,

bearing 5 rows of setae on distal two-thirds, these

one half length of scape; segments 2-7 of funicle

bearing setae on ventral margin, these equal to

1.5 times the 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 glabrous; surface minutely

granulate-punctate with minute, shallow punc-

tures; anterior fifth bearing 2-3 rows of yellow-

brown 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, remaining elytral surface minutely

granulate. Declivital interstriae bearing uniseriate

rows of yellow-brown scales. 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 strongly convex and

protuberant, height of declivity behind much less

than length of sternite 3.

Male genitalia. Median lobe strongly arcuate,

lateral and apical margins with more sclerotiza-

tion, apex rounded with flat lateral margins; api-

cal orifice membranous with sclerotized veins; lat-

eral folds on basal third contiguous. Median struts

half of body length. Internal sac central area lightly

sclerotized, basal and lateral areas of seminal valve

sclerotized ( Fig. 61). Tegmen semi-circular, ven-

tral side elongated proximally. Spicule nearly

longer then aedeagus, sickle-shaped.

Female. Similar to male except epistoma less

impressed, less than a quarter length of head and

unarmed; apical margin bearing a row of hair-like

setae. Frons flat, with medial area slightly im-

pressed and joining with the impressed area of the

epistoma. Each gena with a circular mycangium

(Fig. 4c). Segments 4-7 of funicle bearing scattered

setae less than the length of 3 segments. Pronotal

Distribution. Brazil (Pará), Ecuador (Napo).

Biology. Unknown.
