Cyphocoleus heterogenus Chaudoir, 1877 Figures 28 , 49 , 53-54 , 62 , 68 , 77 Diagnosis. Beetles as large as Cyphocoleus prolixus , standardized body length 10.8-13.1 mm, but head and prothorax much broader, the head much more developed at the expense of pronotal length (Figs 48 , 49 ).Though the mandibles are shorter than in Cyphocoleus prolixus , with mandibular length 2.0 x distance from antennal socket to anterolateral margin of labrum, the antennae are longer, with scape length 4.1 x maximal breadth. The pronotum is unique among Cyphocoleus due to the extremely elongate, acutely protruded front angles. The presence of three dorsal elytral setae is shared only with Cyphocoleus ovicollis (Fig. 82 ), all other species exhibiting more reduced numbers of dorsal elytral setae or none at all. Description (n = 5). Head capsule broad, robust, distance from clypeal-labral suture subequal to width across eyes; frons broadly convex, with small chevron-shaped indentation medially between front margins of eyes; eyes moderately large, convex, 28 ommatidia across horizontal diameter; eyes moderately small, convex, ocular ratio 1.35-1.42; only posterior supraorbital seta present; neck distinctly impressed just before juncture with prothorax; gena glabrous, subgenal seta absent. Pronotum distinctly cordate, margin sinuately constricted basally; lateral marginal bead present from acute front angles to just mesad tightly rounded hind angles; median base margin by fine bead; proepisternum slightly bulging, visible in dorsal view along middle half of prothorax; median longitudinal impression shallow, finely incised; anterior transverse impression broad, shallow, obliquely meeting median impression; anterior callosity slightly convex; prosternal process with fine median ridge anteriorly between procoxae, medially depressed on ventral and posterior face. Elytra broadly ovoid, disc moderately convex with side only moderately depressed relative to disc; elytral striae impunctate; parascutellar seta present, articulatory socket not upraised above elytral surface; elytra narrow basally, humeri obtuse-angulate at base of fifth stria; lateral margin straight to slightly concave lateral anterior series of lateral elytral setae; lateral elytral setae arranged as 6 + 1 + 7-8; subapical and apical elytral setae present; subapical sinuation distinctly invaginated, curvature greatest just mesad obtusely rounded juncture of sinuation and lateral margin. Mesepisternum impunctate; metepisternal dorsal length 0.86 x diagonal width. Abdomen of males with apical margin of apical ventrite distinctly notched, the invagination smoothly rounded; apical ventrite of male with one seta each side, of female with two setae each side. Legs elongate, gracile, mt1 length/tibial length = 0.26; metacoxae bisetose; tarsomeres with short sparse setae dorsally; mt4 outer lobe 1.7 x median length, 4-5 ventrolateral setae each side. Microsculpture of frons and vertex a stretched isodiametric mesh; pronotal disc and discal elytral intervals covered with fine transverse lines; dorsal surface of body apparently glabrous except for standard macrosetae; pro-, meso-, and metasternum and visible abdominal ventrites with sparsely distributed pelage of very short setae. Coloration of dorsum rufopiceous with cyanotic to cupreous iridescence due to microsculpture; antennae dark rufous, paler apically, palps brunneous; basal abdominal ventrites rufopiceous, ventrite 6 rufobrunneous, margin narrowly brunneous; femora rufopiceous, tibiae rufobrunneous, tarsi slightly paler, dark rufous. Male genitalia (n = 8). Male aedeagal median lobe robust, broadly parallel sided in basal 3/4 of length, then evenly narrowed to projected, narrow tip, dorsoventral breadth at midlength 0.25 x distance from tip to base of closed basal bulb (Fig. 53 ); lobe shaft slightly melanized, the internal sac visible through lobe wall in uneverted position; lobe apex tapered to tightly rounded tip, length distad ostial opening 2.5 x dorsoventral breadth; internal sac evenly covered with short melanized spicules in distal half, of sinuous shape but sides parallel in extension (Fig. 54 ). Female reproductive tract (n = 2). Bursa copulatrix vase-shaped, basally stalked, distance from base of gonocoxites to spermathecal basal sclerite 2.4 x maximum breadth (dissection compressed under cover slip) (Fig. 62 ); bursal walls thin, translucent, with broad band of spicules lining lumen near midlength; basal gonocoxite with apical fringe of seven to eight setae (Fig. 68 ); apical gonocoxite broadly rounded at apex with three lateral ensiform setae. Type . Holotype male (MNHN): Ex Musaeo / Chaudoir (red-inked white label with red border) // HOLOTYPE / Cyphocoleus / heterogenus / Chaudoir 1877 (black-bordered red label). Holotype status is based on Chaudoir's (1887: 193) statement "Cet insecte m'a ete cede par M. Salle." Yahoue hereby designated type locality. Distribution and habitat. Found throughout Grande Terre, from Mt. Ignambi and Mt. Panie on the north, to Foret de Thi on the south (Fig. 77 , Suppl. material 3). Beetles have been collected from pyrethrin spray samples from trees and logs, with and without epiphytes, from under a rock near a dead tree, from Freycinetia axils, and by hand during night.
