Diagnosis.

This species shares the elongate prothorax with transversely wrinkled notum and acutely projected front angles with Cyphocoleus monteithi , but the elytra are very flat, and the elytral striae distinctly punctate, the punctures expanding strial breadth (Fig. 99 ). The pronotum is narrowly trapezoidal, with broadly rounded hind angles and a deep transverse groove defining a broadly elevated pronotal basal margin, APW/BPW = 1.28-1.40. Based on the two examined specimens, it appears that this species carries a layer of environmental varnish similar to that observed for Cyphocoleus monteithi above (Fig. 85 ), not the abundant layer of environmental debris that coats individuals of Cyphocoleus mirabilis , Cyphocoleus moorei , and Cyphocoleus lescheni (Figs 100-103 ). Standardized body length 7.3-7.7 mm.

Description

(n = 2). Head capsule ovoid with deeply constricted neck, genae distinctly incurved at back of head; frons with large, shallow chevron-shaped medial impression, frontal grooves broad and subparallel; eyes small, moderately convex, ocular ratio 1.30-1.50; supraorbital setae absent; mandibles moderately elongate, length 2.5 × distance from antennal articulatory socket to anterolateral margin of labrum; gena glabrous. Pronotum narrow, tubular, MPW/PL = 0.63-0.67; median longitudinal impression deep, interrupting orientation of deep transverse wrinkles, terminated anteriorly as a deep pit; anterior marginal bead very broad, the deep groove just posterad bead interpreted as anterior transverse impression; proepipleuron and proepisternum bulging outward, visible in dorsal view for much of pronotal length, proepisternum smooth. Elytra broadly ellipsoid, MEW/EL = 0.68-0.69; humeri broadly angulate laterad depressed scutellum and parascutellar interval; parascutellar setae present, articulatory socket papillate, elevated above elytral surface; elytral striae deeply incised, punctate, the punctures separated by about 5 × puncture diameter; elytral intervals distinctly convex, the sutural, third, fifth, and seventh interval subcarinate, most evidently so basally; dorsal elytral setae absent; lateral elytral margin straight to slightly concave laterad anterior series of lateral elytral setae; lateral elytral setae arranged as 6 + 6; subapical elytral seta present, apical seta absent; subapical sinuation distinctly concave, sinuation subangulately meeting lateral margin; elytral apices broadly rounded, margin deeply invaginated at fused suture. Mesepisternum impunctate; mesepisternum with dorsal length subequal to diagonal width. Abdomen of males and females with apical ventrite broadly, slightly concave medially; males with one seta each side of apical margin of apical ventrite, females with two setae each side. Legs gracile, moderately long; metacoxae bisetose; tarsomeres relatively broad and short, mt1 length 0.21 × tibial length; mt4 with long, broad apical lobes, length to apex of outer lobe 2.67 × median tarsomere length, 3-4 ventrolateral setae each side. Microsculpture reduced, frons with surface shiny, transversely stretched isodiametric mesh traceable over portions of surface; pronotum glossy with fine transverse lines visible over portions of surface; elytral glossy on disc with transverse lines visible apically; body surface - head, pronotum, elytra, and ventral surfaces - with sparse pelage of very short setae (these setae may be removed in part by cleaning). Coloration of head and pronotal disc rufopiceous; prothoracic ventrites piceous; elytra rufobrunneous; thoracic and abdominal ventrites rufopiceous, apical abdominal ventrite apically brunneous; femora and tibiae rufobrunneous, tarsi brunneous.

Male genitalia (n = 1). Male aedeagal median lobe robust, broadly parallel sided from base to apex of ostial opening, dorsoventral breadth at midlength 0.25 × distance from tip to base of closed basal bulb (Fig. 89 ); lobe shaft slightly melanized, the internal sac visible through lobe wall in uneverted position; lobe apex parallel-sided, dorsoventral breadth slightly longer than length; tip of lobe evenly rounded.

Female reproductive tract (n = 1). Bursa copulatrix broadly columnar, distance from base of gonocoxites to spermathecal basal sclerite 2.7 × maximum breadth (dissection compressed under cover slip) (Fig. 65 ); bursal walls thin, translucent, the lumen smooth; basal gonocoxite with apical fringe of five setae (Fig. 73 ); apical gonocoxite broad basally, but narrow for much of length, with narrowly rounded apex and two lateral ensiform setae.
