Cardiodactylus cheesmani Otte, 2007a: 350 ; 2007b: 31.

TYPE MATERIAL. — Vanuatu. [Tafea Province], Tanna Is., X.1930, L. E. Cheesman, ♂ holotype ( BPBM 16,778). — Same locality, date and collector as holotype, ♀ paratype. Not examined.

MATERIAL EXAMINED. — [ Vanuatu] Nouvelles-Hébrides. [Province Tafea], Tanna Is., 1924, E. Aubert de la Rüe, 1 ♀, identified C. gaimardi by L. Chopard ( MNHN- ENSIF1179).

TYPE LOCALITY. — Vanuatu, Tanna Is.

DISTRIBUTION. — Vanuatu, Tanna Is.

DIAGNOSIS. — Species of average size, comparable to C. tankara n. sp. (see below). Colouration light brown, little contrasted. Dorsal disk of pronotum with incomplete lateral bands. Male FW with a clear light crescent including posterior part of mirror; male genitalia close to that of C. tankara n. sp., but differing by the shape of pseudepiphallic sclerite (dorsal crest not asymmetrical, lack of basal protuberance near median shrinkage).

REDESCRIPTION

In addition to the characters given by Otte (2007b): general colouration light brown, little contrasted. Scapes yellowish brown. Fastigium 1.5 times as long

A B

as wide, median ocellus yellow. Pronotum: dorsal disk trapezoidal, slightly bisinuated posteriorly. Fore tibiae not widened at tympana level. Hind tibiae dorsal face with 6 inner and 14 outer spines above spurs, 4 inner and 10 outer spines between spurs (n = 1). Tarsomeres III-1 with 4 spines on dorso-external edges (n = 1). FWs slightly longer than abdomen; hind wings forming a short grey brown tail about 1.5 times as long as pronotum. Cerci homogeneously brown.

Female

FW colouration ( Fig.5D ): dorsal field cells and longitudinal veins homogeneously brown, transverse veins whitish on FW anterior half; FW base with whitish sclerotization, including bases of 1-3A,CuP, CuA and MP; whitish area on anterior lateral angle, including MA/MP area, part of CuA and associated transverse veins.Area between CuA and CuP dark brown,except 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 with7 bifurcating veins.Ovipositor:shorter than hind femora, as in C. tankara n. sp.; apex dorsal and ventral edges not clearly denticulate ( Fig. 6E ).
