Cybocephalus New Species 2

 (Figs. 6-12-6-15, 6-24)

 Diagnosis. Male and female are black. The antennal club is smaller than the eye

and the terminal club antennomere is truncate and wider than long (Fig. 6-12), separating

this species from C. aciculatus, C. randalli, and Cybocephalus new species 3. The

terminal club antennomere is not as short as in Cybocephalus new species 1. In males,

the basal plate (Fig. 6-15) and median lobe (Figs. 6-13 and 6-14) are easily distinguished

from all other species.

 Description. Male. Form: Elongate oval; contractile; strongly convex dorsally.

Length: 1.4 mm (measured from apex of clypeus to apex of elytra); breadth: 1.0 mm

(measured across elytral humeri). Color: Head, thorax, elytra and underside black,

posterior margin of elytra yellowish and translucent; legs and antennae brown or black.

Head: Broad and convex, clypeus moderately produced, narrow, and slightly reflexed.

Eyes large, oblong, with internal margins distinct. Genae not visible from above. Dorsal

surface smooth under 100 times magnification, distinctly alutaceous and finely punctate.

Antennae 11-segmented including a club with 3 antennomeres, club length about 1/2-%

size of the eye. Club flat and distinctly separated from funicle and with a distinctly

serrated margin. First club antennomere wider than long, second club antennomere larger

than either first or third club antennomere and about as long as wide. Terminal club

antennomere truncate (Fig. 6-12), setose and a little wider than long. Antennomere 3 as

long or slightly longer than antennomeres 4 and 5 combined. Pronotum: Strongly

convex, lateral margins curved; anterior angle more narrowly arcuate than posterior.

Surface distinctly alutaceous with fine punctation. Scutellum: Alutaceous and triangular

with straight to slightly convex margins. Elytra: Uniform width narrowing at apical 1/5.
