Diagnosis.

This second of the species triplet with anterior and posterior pronotal processes is unique in the absence of a lateral carina joining the processes, the pronotum fused to proepipleuron without any evidence of the shared suture (Fig. 102 ). The pronotal processes are both columnar, the anterior process half the height of the posterior, and both topped with a tuft of approximately nine club-shaped setae. The elytral intervals are distorted in this species, with the second interval absent basally due to convergence of the sutural and third intervals. Conversely, the fourth interval appears split basally, resulting in the highly carinate fifth interval maintaining its fifth place position relative to the inner intervals throughout its length. The less convex sixth interval lies just laterad the carinate fifth interval, with the seventh interval very low and in part confused with the sequence of lateral elytral setae. The eyes of these beetles are very small in diameter, though slightly convex, with eight ommatidia horizontally across the diameter: the same ommatidial count as Cyphocoleus lescheni below. Standardized body length 4.8-5.2 mm.

Description

(n = 2). Head capsule narrow elongate, genae parallel behind eyes, basally constricted to narrowly constricted neck (Fig. 102 ); frons depressed between the eyes relative to convex vertex; frontal grooves deep, broad, depressed mesad bases of antennae; supraorbital setae absent; mandibles moderately elongate, length 2.1 × distance from antennal articulatory socket to lateroapical margin of labrum; antennae only moderately elongate, apical antennomeres filiform; scape greatly swollen, flattened dorsoventrally so that it assumes the profile of a cricket bat at midlength, scape length 2.3 × maximal breadth; gena glabrous except for pelage, subgenal seta absent. Pronotum evenly ellipsoid in dorsal view, MPW/PL = 0.77; pronotal disc convex in both lateral and longitudinal dimensions, median base depressed relative to center of disc, with obsolete marginal bead defined by very shallow groove near margin; median longitudinal impression shallow, smooth, best defined by darker cuticle at deepest part; anterior transverse impression interpreted as deep transverse groove that defines upturned anterior collar; proepisternum bulging outward, visible in dorsal view, smooth; prosternal process broadly, medially depressed near front of procoxae, more narrowly depressed medially on ventral face, broadly medially depressed on posterior face. Elytra broad, moderately convex, little depressed laterally; scutellum depressed and basal margin medially inflexed at suture; humeri evenly sloped from scutellum to narrowly rounded margin just laterad front of anterior series of lateral elytral setae; parascutellar and dorsal elytral setae absent; fifth elytral interval subcarinate, more elevated than other moderately convex intervals; lateral elytral setae arranged as 6 + 3 + 3, their articulatory sockets papillate, upraised above surrounding cuticle; subapical elytral seta present, apical seta absent; subapical sinuation distinctly concave, most concave portion of sinuation convexly upraised; elytral apices broadly rounded, separated by moderate invagination centered on fused suture. Mesepisternum impunctate; mesepisternum with dorsal length 1.1 × diagonal width. Abdomen of female with broad, shallow concavity medially, two setae each side. Legs moderately long, mt1 length/tibial length = 0.21; metacoxa bisetose; mt4 length to apex of outer lobe 1.2 × median length, 4-5 ventrolateral setae each side. Microsculpture of head absent, frons and vertex glossy; pronotal disc and lateral sclerites glossy; elytra without microsculpture on higher portions of intervals, fine transverse lines traceable in deeper portions of striae and punctures; head and pronotum with pilose pelage of elongate club-shaped setae; pronotal processes with tufts of pad dle-like setae at apices; elytral intervals lined with series of paddle-like setae of length similar to tufts on pronotal processes; elytral margin lined with very short paddle-like setae; ventral surfaces of head, thorax, and abdomen covered with sparsely distributed pelage of short microsetae, with similar-lengthed setae covering anterior surfaces of femora, dorsal surfaces of tibiae; tarsomeres setose dorsally, the setae arranged in two dorsolateral longitudinal series. Coloration of head, prothorax, elytra, and thoracic and abdominal ventrites rufous; antennal scape dark, rufopiceous, outer antennomeres 2-11 brunneous; femora rufoflavous, tibiae and tarsomeres brunneous.

Male genitalia. Male aedeagal median lobe robust, broadly parallel sided in basal half, ventral margin slightly convex near midlength, dorsoventral breadth at midlength 0.2 × distance from tip to base of closed basal bulb ( Park and Will 2008; Fig. 3K ); lobe apex tapered to subacuminate, slightly downturned tip, dorsoventral breadth 0.25 × distance from distal margin of ostial opening to tip.

Female reproductive tract. Not examined (see Park and Will 2008).

Type.

Holotype male (MNHN): NEW CALEDONIA, 21°45'S, 166°09'E, Ningua Reserve Camp, 1100 m, 12-13.xi.2001, C. Burwell & G. Monteith, pyrethrum, trees & logs, 8639 (not examined; identification based on female paratype (QMB)) .

Distribution and habitat.

Known from slightly north of the distribution of Cyphocoleus mirabilis along the SarraméaCanala Road near Table Unio, though with a broad sympatric overlap with that species ranging from Col d’Amieu to Ningua Reserve (Fig. 81 , Suppl. material 3). Specimens have been found in leaf litter, and by pyrethrin fogging of trees and logs. The elongate club-shaped setae over the body surface are associated with a 0.2 mm thick environmental patina incorporating plant-based detritus (Fig. 102 ).
