Diagnosis. This species is closely related to C. quadridens and C. costatus . Adults are readily distinguished by their large size, by the unarmed apical epistomal margin, by a distinctive orange and black color pattern described below, by the absence of a carinate costa on the eighth interstriae Figure 40. Camptocerus zucca , 4.0- 4.1 mm, holotype

male. Lateral (A), dorsal (B); male head anterior (C), and by the sparse setae on the declivity.

anterior oblique (D); female head anterior (E), anterior The female is distinguished from other females oblique (F). in the costatus clade by the distinctive color pattern, by the larger size, by the unimpressed striae and by the short, fine setae on the interstriae.

Description (male). 4.0- 4.1 mm long (mean = 4.05 mm; n = 2); 1.9 times as long as wide. Antennal scape and club black, funicle orange; epistoma and frons orange, gena black; protibia orange with black margins, profemur and meso- and metathoracic legs black with orange patches, coxae brownish-orange; pronotum orange with a black triangle extending from the apex to the basal third; elytra black, with each elytron displaying an orange oval encompassing the area from the basal margin of the disk and to the apical fifth of the elytra and from the sutural interstriae to interstria 8; ventral surface of thorax and abdomen black. Teneral adults are pale orange with dark spots.

Epistoma excavated, expanded to less than a quarter length of head, apical epistomal margin unarmed; surface shagreened; each lateral margin with a sub-acute, arcuate costa angled proximally, lined entirely with setae; basal epistomal unarmed (Fig. 2e). Frons strongly excavated; excavation borders the ocular margin; surface shagreened; bearing dense, erect, pale yellow white hair-like setae of equal length. Antennal scape elongate and broadly rounded distally, bearing a brush of setae on distal half, those as long as scape; ventral margin of segments 2-7 bearing brushes of setae, these equal to the 1.5 times the length of funicle; segments 2-7 of funicle bearing hair-like setae on dorsal margin, these half the length of those on ventral margin; anterior face of the club setose, with a partial septum.

Apical pronotal margin broadly rounded (Fig. 5a), area between eyes glabrous; surface smooth, minutely and nearly indistinguishably punctured; median line devoid of punctures; anterior fourth bearing 5-6 transverse setae; a row of setae above lateral carinae; pronotal base recurved (Fig. 8b); carina on lateral margin type D (Fig. 7d).

Scutellum shape type I ( Fig. 12i ).

Elytral sides parallel, narrowing to a smooth apex; base never tumid from interstriae 7-9. Disk with shallow rugosities to interstria 3, remaining disk smooth; basal margin with a weak carina extending to scutellar apex (Fig. 11c); striae not impressed. Declivital interstriae 4 times the width of striae, each interstriae with 2-3 long setae, uniseriate, those on declivital interstriae 1-5 2-3 times as long as those on interstria 6; 3 lateral rows of short setae present on the lateral margin from sternite 1 to the suture. Tenth interstriae with a carina shorter than metepisternum. Metepisternum shape type C ( Fig. 9c ); setae bifid. Mesosternum shape type O ( Fig. 10o ).

Male genitalia not examined.

Female. Similar to male except epistoma less than a quarter length of head. Frons flat; surface shagreened, short, sparse, setae present only on lateral margins. Each gena with a circular mycangium (Fig. 4c). Segments 3-7 of funicle bearing setae on dorsal and ventral margins, these less than length of 4 segments. Declivital interstriae bearing short semi-recumbent bristles.

Specimens examined. (2M, 1F)

Distribution. Ecuador (Napo).

Hosts. Unknown.

Biology. Unknown.

Etymology. Zucca (Italian) = pumpkin (noun in apposition). In reference to this species’ jack-o-lantern appearance.
