Diagnosis.

In juxtaposition to its cryptic adelphotaxon, this species can be diagnosed by the flatter eyes, ocular ratio 1.41-1.44, and presence of two apical abdominal setae in the males of this species - one seta each side of apical visible abdominal ventrite - versus four apical abdominal setae - two each side - in males of Cyphocoleus parovicollis . The pronotum is generally broader basally among individuals of this species - MPW/BPW = 2.04-2.29 - versus values of 1.87-2.10 in Cyphocoleus ovicollis . A male dissection will allow attribution of a series of specimens, with the male of Cyphocoleus ovicollis exhibiting an internal sac with a robust, mound-shaped tooth on the right side (Figs 58 , 59 ). The allopatric geographic distributions also provide information as Cyphocoleus ovicollis (Fig. 78 ) is distributed to the south of Cyphocoleus parovicollis . Standardized body length 9.1-11.0 mm.

Description

(n = 5). (The description of Cyphocoleus parovicollis can serve for this species, with the following exceptions). Head capsule with mandibles elongate, length 2.4 × distance from antennal articulatory socket to anterolateral margin of labrum. Elytra more broadly subellipsoid, MEW/EL = 0.71-0.73; three dorsal elytral setae uniformly present; lateral elytral setae arranged as 6 + 1(0) + 7(8). Mesepisternum dorsal length 0.8 × diagonal width.

Male genitalia (n = 5). Male aedeagal median lobe robust, broadly parallel sided in basal half, then tapered to narrowly rounded tip, dorsoventral breadth at midlength 0.2 × distance from tip to base of closed basal bulb (Fig. 57 ); lobe shaft brunneous, the internal sac obscured in uneverted position by the moderately melanized lobe wall; lobe apex with evenly rounded tip, length distad ostial opening subequal to breadth; internal sac broadest at midlength, with large sclerotized plaque-like tooth on right side, and a ring of melanized microtrichia apically near gonopore (Figs 58 , 59 ).

Female reproductive tract (n = 1). Bursa copulatrix vase-shaped, basally stalked, distance from base of gonocoxites to spermathecal basal sclerite 1.7 × maximum breadth (dissection compressed under cover slip) (as in Fig. 63 ); bursal walls thick, heavily pigmented by Chlorazol Black stain, with broad band of thick, densely packed spicules lining lumen over broadest part of bursa; basal gonocoxite with apical fringe of six to seven setae (Fig. 70 ); apical gonocoxite acuminate with narrowly rounded apex and three lateral ensiform setae.

Type.

Holotype male (MNHN): Cyphocoleus ovicollis / Fvl. // Ex-Musæo / Mniszech (white label with black border) // HOLOTYPE / Cyphocoleus / ovicollis / Fauvel 1882 (black-bordered red label). Type locality noted by Fauvel (1882: 248) as "probablement à Ourail," with Bourail hereby designated type locality.

Distribution and habitat.

The known distribution northern portions of Province Sud, from Bourail and Col d’Amieu on the north to Mt. Do and Ningua Reserve to the south (Fig. 78 , Suppl. material 3). Specimens have been obtained in pyrethrin samples from trunks and logs with and without epiphytes, via hand collecting, with one series of six specimens collected in a flight intercept trap, without doubt having climbed onto and into the trap.
