Diagnosis.

The diagnosis of Cyphocoleus cordatus should be consulted to determine the characters that uniquely circumscribe this species and its adelphotaxon (Fig. 46 ). Cyphocoleus cardiopterus (Fig. 124 ) can be diagnosed from its sister species (Fig. 123 ) by the presence of distinctly punctate elytral striae, the punctures expanding strial breadth to apex of elytra. The two species can also be diagnosed by elytral microsculpture; isodiametric in this species versus transverse-line microsculpture in Cyphocoleus cordatus . Standardized body length 6.5-7.2 mm.

Description

(n = 5). (The description of Cyphocoleus cordatus can serve for this species, with the following exceptions to accompany the diagnostic characters presented above). Lateral elytral setae arranged as 6 + (1) + 7(8), articulatory sockets slightly upraised above cuticular surface, not papillate; elytral disc rufopiceous, without iridescent reflection.

Male genitalia (n = 1). Male aedeagal median lobe robust, broadly parallel sided over basal 2/3 of length, dorsoventral breadth at midlength 0.3 × distance from tip to base of closed basal bulb (Fig. 136 ); lobe apex only briefly extended beyond ostial opening, tip rounded; internal sac with broadly angled though lightly sclerotized area on ventral surface, the remaining sac surface with lightly sclerotized, very short microtrichia; sac length 2 × breadth. The broad, lightly sclerotized region on the ventral sac surface corresponds in position to the heavy sclerotized sac tooth observed in males of Cyphocoleus cordatus , supporting the homology of these structures. That the structures are not identical is supported by the similar sclerotization of the median lobe, and by the different eye configurations (Figs 123 , 124 ) that also diagnose these species.

Female reproductive tract (n = 1). Bursa copulatrix vase-like, basally stalked, distance from base of gonocoxites to spermathecal basal sclerite 2.75 maximum breadth (dissection compressed under cover slip) (Fig. 109 ); bursal walls thin, translucent, lumenal surface with thick band of long thick setae surrounding midlength; basal gonocoxite with apical fringe of four to five setae (as in Fig. 116 ); apical gonocoxite narrowly subtriangular with narrowly rounded apex and two lateral ensiform setae.

Type.

Holotype female (MNHN): Ex Musæo / Chaudoir (red-inked white label with red border) // HOLOTYPE / Cyphocoleus / cardiopterus / Chaudoir 1877 (black-bordered red label). Holotype status is based on Chaudoir’s (1877: 196) statement: “C’est également de M. Sallé que j’ai eu cet insecte." Mt. Mou hereby designated type locality .

Distribution and habitat.

This species is known from Mt. Mou and near Mt. Dzumac, occupying a distribution allopatric and to the north of its adelphotaxon, Cyphocoleus cordatus (Fig. 137 , Suppl. material 3).
