Diagnosis.

This species is characterized by presence of the posterior supraorbital seta, a configuration shared, among the nine Cyphocoleus species with orbicular pronotum and cordate elytra (Figs 121-125 , 161-164 ), only with Cyphocoleus subulatus and Cyphocoleus iledespinsensis . This supraorbital seta is not close to the eye, but positioned far back on the head capsule close to the constricted neck. Cyphocoleus latipennis deviates from the other two species in exhibiting a very glossy vertex and glossy to transversely lined elytral intervals, versus a vertex covered with isodiametric sculpticells, and elytra with evident transverse-mesh microsculpture, best evidenced in the strial depressions. Standardized body length 5.1-7.5 mm.

Description

(n = 5). Head capsule narrowly ellipsoid, genae gradually narrowed to moderately constricted neck; eyes only slightly convex, ocular ratio 1.46-1.53, 13-18 ommatidia across horizontal diameter of eye; frons with paired, elongate-ellipsoid depressions that surround a narrow elevated median carina; frontal grooves deepest and broadest just mesad eyes, sinuously convergent toward clypeus; mandibles elongate, length 2.3 × 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, slightly protruded; median base depressed relative to disc, lateral margin sinuate anterad median basal margin that is straight across base; median longitudinal impression deep, broad, extended to anterior margin; anterior transverse impression defined by shallow groove where discal wrinkles terminate, anterior callosity crossed by numerous longitudinal wrinkles; proepisternum extended beyond marginal bead, visible in dorsal view, smooth; prosternal process broadly, medially depressed anteriorly and on ventral face, narrowly carinate posteriorly. Elytra broadly ovoid, depressed mediobasally between parascutellar setae; basal groove subangulate basad sutural stria, lateral margin broadly and evenly extended outside humeral angle; discal intervals moderately convex, all intervals of subequal convexity; elytral striae deep, punctate, the punctures limited at the deepest portion of strial depression (and so easy to miss in uncleaned specimens); parascutellar seta articulatory socket 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; subapical sinuation moderately developed, lateral portion of concavity joined to depressed lateral margin in broad curve; elytral apices conjoined, no invagination of apical margin at fused suture. Mesepisternum impunctate; metepisternal dorsal length 1.0 × 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 setae each side. Legs moderately elongate; metacoxae bisetose; mt1 length/tibial length = 0.27; mt4 length to apex of outer lobe 1.8 × median tarsomere length, 3-4 ventrolateral setae each side. Pelage little developed, glossy head capsule, pronotum, and elytra with only sparsely distributed, very short microsetae. visible only in lateral view; pro-, meso-, and metasternum with evident pelage of microsetae, the setae longer than on dorsal surface; second and third abdominal ventrites with short, sparse microsetae medially, other ventrites and legs glabrous except for macrosetae. Coloration of body dorsum piceous, mouthparts rufopiceous; ventral surfaces of head and prothorax and thoracic sternites piceous, elytral epipleuron and abdominal ventrites to rufopiceous to dark rufous; femora dark rufous except for paler, rufoflavous apex, tibiae and tarsi rufobrunneous.

Male genitalia (n = 14). Male aedeagal median lobe gracile, median lobe constricted near midlength, dorsoventral breadth at midlength 0.13-0.16 × distance from tip to base of closed basal bulb (Figs 126-133 ); lobe apex variously tapered to parallel sided basad broadly (Figs 128 , 129 ) to narrowly rounded (Figs 126 , 127 , 130-133 ) tip; internal sac membranous without melanized microtrichia, length 2 × breadth (Fig. 129 ).

Female reproductive tract (n = 3). Bursa copulatrix narrowly elongate, distance from base of gonocoxites to spermathecal basal sclerite 7 × maximum breadth (dissection compressed under cover slip) (Fig. 108 ); 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 six setae (Fig. 115 ); apical gonocoxite subtriangular with pointed apex and two lateral ensiform setae.

Distribution and habitat.

This is the most broadly distributed Cyphocoleus species, distributed along the length of Grande Terre (Fig. 138 , Suppl. material 3). Specimens have been collected using pyrethrin fog applied to trunks and logs, from leaf litter, and also from flood debris.
