( Figs 5E ; 6F ; 7 P-R)

TYPE MATERIAL. — [ Vanuatu] Nouvelles-Hébrides. [Province Shefa], Epi Is., Baie de Nelson, 1935-1936, E. Aubert de la Rüe, ♀ holotype (MNHN-ENSIF1116).

TYPE LOCALITY. — Vanuatu, Epi Is., Baie de Nelson.

ETYMOLOGY. — Species named after the type locality.

DISTRIBUTION. — Vanuatu, Epi Is.

DIAGNOSIS. — Species of average size, close in size and colouration to C. tankara n. sp., C. cheesmani and C. gagnei Otte, 2007 . Female differs from other species by patterns of whitish sclerotization on FW base, and shape of copulatory papilla, more elongate and apex larger than in C. tankara n. sp. and C. cheesmani (not observed in C. gagnei ).

DESCRIPTION

Species of average size. General colouration brown, little contrasted. Fastigium black, 1.5 times as long as wide, median ocellus yellow. Head dorsum with 6 wide dark brown bands and 2 yellow bands behind eyes. Face with a yellow band above clypeus; 2 dark brown curved patterns diverging from front head to below antennae. Pronotum: dorsal disk trapezoidal, slightly bisinuated posteriorly; lateral lobes dark brown except ventral margin whitish. Fore tibiae not widened at tympana level. Hind tibiae dorsal face with 6 inner and 12 outer spines above spurs, 6 inner and 10 outer spines between spurs (n = 1). Tarsomeres III-1 with 4 spines on dorso-external edges (n = 1). FWs as long as abdomen; hind wings making a short dark brown tail about 1.5 times as long as pronotum. Cerci

yellowish brown mottled with dark brown and banded apically.

Male

Unknown.

Female

FW colouration ( Fig. 5E ): dorsal field cells and longitudinal veins homogeneously brown; FW base with whitish sclerotization, including bases of veins 1-2A, CuP, CuA and MP; restricted whitish area on anterior lateral angle, including bases of CuA, MP and their associated transverse veins; part of CuA and MP whitish at third of length. Areas between CuA and CuP and between bases of CuA1 and CuA2 with whitish transverse veins. Area between MP and R brown, R bifurcating veins whitish. FW venation: 10 strong longitudinal veins on dorsal field (including 1-3A). R with 7 bifurcating veins. Ovipositor: quite short, as in C. tankara n. sp.; apex dorsal edge denticulate; ventral edge smooth ( Fig. 6F ).

Female genitalia: copulatory papilla ( Fig. 7 P-R): shape more elongate than C. tankara n. sp. and C. cheesmani ; dorsal and ventral sides concave, dorsal surface not plicate; apex larger than in other species, slightly curved ventrally.
