Camptocerus charpentierae Schedl 1970: 582 .

Holotype: male, FRENCH GUIANA:

Massikiri-Haut Oyapock, 18.xi.1969,

(Balachowsky-Gruner Guyane Mission),

Schedl Collection ( NHMW).

Diagnosis. Adults of both sexes of C.

charpentierae can be distinguished by the black

abdomen, convex second abdominal sternite and

by the declivital interstriae bearing uniseriate,

short, pale yellow-brown scales.

Redescription (male). 3.8-4.5 mm long (mean = 4.3 mm; n = 6); 1.7-2.0 times as long as wide. Head and antennae dark red-brown; abdomen, elytra, and legs black. Pronotum and legs may be red to black, but are typically reddish-brown. Figure 26. Camptocerus charpentierae , 3.8 – 4.5 mm,

holotype male. Lateral (A), dorsal (B); male head Epistoma strongly excavated, expanded to

anterior (C), anterior oblique (D); female head anterior greater than quarter length of head; surface (E), anterior oblique (F). shagreened; bearing 6 rows of setae lateral to the median line; 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 bordering the ocular margin; surface shagreened; bearing 1 erect golden setae lateral to the median

line, surface clearly visible; 20-30 setae on lateral and dorsal margins. Antennal scape elongate and expanded distally, distal three-quarters bearing dense setae, those length of scape; segments 2-7 of funicle bearing setae on the ventral margin, those 1.5 times the length of funicle; setae on the dorsal margin, those less than the length of 5 segments; ventral margin bearing setae 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; 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 the striae 1 to interstriae 4 and from the base to just beyond the scutellum, the remaining elytral surface minutely granulate. Declivital interstriae bearing uni- and biseriate rows of pale 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 convex.

Male genitalia. Median lobe flat, proximally wider than distal end, arcuate on distal quarter, lateral and apical margins with more sclerotization; apex broad, set below the level of the median lobe; apical orifice lightly sclerotized; lateral margins folded dorsally. Median struts a third of body length. Internal sac central area lightly sclerotized; faint sclerotization on the dorsal part of median lobe above seminal trough; seminal trough proximal end “V” shaped ( Fig. 57). Tegmen and spicule destroyed in dissection.

Female. Similar to male except epistoma less impressed, less than a quarter length of head and unarmed; with a 4 rows of hair-like setae on apical margin. Frons flat, with medial area slightly impressed and joining with the impressed area of the epistoma; punctures small and shallow medially, larger and deeper laterally. Each gena with a circular mycangium (Fig. 4c). Segments 1-7 of funicle bearing scattered setae less than the length of 3 segments. Pronotal area between the eyes lined with scales.

Discussion. Wood (2007) considered this species to be a synonym of Camptocerus cinctus . Camptocerus cinctus is herein recognized as a synonym of C. suturalis . Camptocerus charpentierae is resurrected based on comparison of the holotype with that of C. cinctus and C. suturalis . Phylogenetic analysis revealed the C. charpentierae (latipilis clade) to be in a separate clade from C. suturalis (aeneipennis clade) ( Fig. 14 ).

Distribution. Brazil (Amazonas), Ecuador (Napo), French Guiana.
