Diagnosis.

Like Cyphocoleus globulicollis (Fig. 125 ) in the transversely wrinkled pronotal disc with deep parasagittal impressions and head without supraorbital setae, but differing through: 1, the much reduced dorsal pelage, the microsetae on head, pronotum, and elytra exceedingly short, visible only in lateral view; and 2, elytral striae distinctly punctate, the punctures broadening striae and separated from each other by about their own diameter (Fig. 161 ). Microsculpture is also better developed in this species, with the vertex of head and the pronotal disc, including elevated portions between transverse wrinkles, covered with an evident transverse mesh. The elytral intervals bear evident isodiametric and slightly transversely stretched sculpticells arranged in an irregular, transverse pattern. Standardized body length 6.4-7.0 mm.

Description

(n = 5). Head capsule broad, genae short, neck only slightly constricted; eyes moderately convex but profile not exceeding curvature of gena on posterior portion of eye, ocular ratio 1.47-1.56, 15-16 ommatidia across horizontal diameter of eye; frons with well-de veloped median carina that is surrounded by transversely wrinkled median spot; frontal grooves narrow between eyes, sinuously extended anterad to a deep, rounded depression just posterad frontoclypeal suture; mandibles elongate, length 2.2 × distance from antennal articulatory socket to anterolateral margin of labrum; antennae moderately elongate, scape length 2.75 × maximal breadth; gena setose, subgenal seta present. Pronotum with front angles rounded, only slightly protruded, very obtuse; lateral marginal bead distinctly sinuate before depressed median base that is margined medially by an irregularly depressed bead continuous with the base of the median longitudinal impression; median longitudinal impression deep, broad, extended nearly to anterior marginal bead, with pit-like depression near juncture with anterior transverse impression; anterior transverse impression a shallow, irregular border on the anterior margin of the discal transverse wrinkles, defining a rugose, longitudinally wrinkled anterior callosity; proepisternum bulging, extended beyond marginal bead, visible in dorsal view, smooth; prosternal process convex anterad procoxae, slightly depressed medially on ventral face, broadly convex posteriorly. Elytra broadly cordate, basal margin slightly concave to base of fourth stria, then posteriorly curved across broad humeri; discal intervals moderately convex, all intervals of subequal convexity; elytral striae broad, deep, punctate, the punctures expanding strial breadth to elytral apex; parascutellar seta present, articulatory socket broadly papillate; dorsal elytral setae absent; lateral elytral setae arranged as 6 + 7, the articulatory sockets papillate; both subapical and apical elytral setae present, the articulatory socket for apical seta smaller, not papillate; subapical sinuation distinctly concave, lateral portion of concavity joined to depressed lateral margin in tightly rounded curve; elytral apices conjoined, margin not invaginated at fused suture. Mesepisternum impunctate; metepisternal dorsal length subequal to diagonal width; metasternum with broad, shallow median fossa at base of metasternal process. Abdomen with apical margin of apical ventrite shallowly concave medially in both males and females; males with one seta each side of apical margin of apical ventrite, females with two seta each side. Legs moderately elongate; metacoxae bisetose; mt1 length/tibial length = 0.23; mt4 length to apex of outer lobe 1.9 × median tarsomere length, 3-4 ventrolateral setae each side. Pelage little developed, thoracic sternites with only a few very short microsetae, and abdominal ventrites and legs apparently glabrous except for macrosetae. Coloration of body dorsum piceous; prosternum piceous; meso- and metathoracic sternites and pleurites rufopiceous; abdominal ventrites rufous with piceous cast, apical margin of apical ventrite paler, brunneous to flavous; femora dark rufous basally and apically, but with flavous band just beyond midlength; tibiae rufous, matching femoral apex; tarsi brunneous.

Male genitalia (n = 3). Male aedeagal median lobe very short, broad, longer left paramere extended more than half distance from lobe tip to base of closed basal bulb (Fig. 153 ); lobe apex broadly extended beyond ostial opening, tip broadly rounded, breadth of apical extension 0.6 × distance from tip to ostial opening; internal sac membranous without melanized microtrichia (uneverted view).

Female reproductive tract (n = 2). Bursa copulatrix columnar, distance from base of gonocoxites to spermathecal basal sclerite 3.5 × maximum breadth (dissection compressed under cover slip) (Fig. 111 ); bursal walls thin, translucent, lumenal surface smooth except for thin band of very fine setae at midlength; basal gonocoxite with apical fringe of five to seven setae (Fig. 118 ); apical gonocoxite subtriangular with pointed apex and two lateral ensiform setae.

Distribution and habitat.

This species is known only from the disjunct localities of Fonwhary in the northern portion of Province Sud, and Yahoué and Nouméa in the south of New Caledonia (Fig. 140 , Suppl. material 3). The lone historical collecting record with ecological information includes a beetle collected in dead leaves at the base of a tree.
