Robillard, Tony, Gorochov, Andrej V., Poulain, Simon & Suhardjono, Yayuk R., 2014, Revision of the cricket genus Cardiodactylus (Orthoptera, Eneopterinae, Lebinthini): the species from both sides of the Wallace line, with description of 25 new species, Zootaxa 3854 (1), pp. 1-104 : 27-29

Cardiodactylus celebae Robillard , n. sp.

( Figs 4 , 7 , 8 , 9B , 17 )

Type material. Male holotype: Indonesia. Celebes [Sulawesi], Pala?? [Palapa or Palaga?], identified Cardiodactylus novae guineae Haan by L. Chopard (MZB-ORTH10450) .

Type locality. Indonesia, Sulawesi .

Etymology. Named after the type locality.

Distribution. Indonesia, Sulawesi.

Diagnosis. Species of average size, coloration brownish with yellow brown patterns, characterized by male FW venation and coloration including a thin yellow line posterior to mirror, and by shape of pseudepiphallic and endophallic sclerites in male genitalia. Species close to C. fruhstorferi n. sp. from which it differs by the length of pseudepiphallus.

Description. Average size for the species group. General coloration little contrasted, brown with yellow areas. Head dorsum with 4 wide dark brown bands little distinct anteriorly, bordered by dark brown lines posterior to eyes ( Fig. 17 ). Fastigium dark brown. Scapes orange brown; antennae with yellowish rings. Face and mouthparts almost homogeneously orange brown, slightly lighter ventral to eyes. Maxillary palpi brown, darker apically. Pronotum: Dorsal disk yellow brown laterally, median area mottled with dark brown. Lateral lobes dark brown, ventral margin yellow. Fore legs yellow brown, with faint dark spots on femur. Median legs and tarsomeres III missing in HT. Legs III homogeneously brown. Hind wing tail dark brown, 1.5 longer than pronotum. Cerci and apex of abdomen damaged in HT.

Male: FW coloration contrasted ( Fig. 9B ), mostly orange brown with yellowish and dark brown areas. Yellow areas include: bases of vein CuA, M and 2A–4A, angle of 1A, chords, harp veins, and a narrow transverse line posterior to mirror. Dark brown areas include region anterior to stridulatory file and external part of e1. Lateral field mostly brown, including posterior part of M/R area; posterior part of R/Sc area yellowish. Projections of Sc yellow, cells between them brown. FW venation ( Fig. 9B ): 1A not clearly bisinuated. CuP missing. Stridulatory file with 166 teeth on the transverse part of the file, and 56 on the longitudinal part, without discontinuity at the level of 1A angle. Harp with 2 w-shaped harp veins and several anterior accessory veins. Mirror area: mirror (d1) longer than wide, not rounded but well defined, separated in two parts by a strong transverse vein, the posterior part small and triangular; d2 wide, well defined, prolonging the mirror, without accessory vein; e1 crossed by an accessory vein. Apical field with 4 cell alignments posterior to mirror. M/R fusion angle acute. Lateral field with 7 projections of Sc and 3 more ventral veins. Subgenital plate color not distinct in HT.

Male genitalia ( Fig. 17C–E ): Pseudepiphallus short, clearly narrowed twice, at mid-length and preapically. Dorsal ridges parallel, forming a narrow gutter. Pseudepiphallic sclerite with wide latero-anterior expansions, membrane between them with thick short setae. Posterior region rounded, widened laterally, with a small rounded translucent area at apex. Apex of rami convergent. Ectophallic arc complete, with a short posterior expansion. Ectophallic apodemes long and wide, their basis with long anterior expansions and short posterior ones. Ectophallic fold with lateral sclerites, apex trilobate, median lobe elongate. Endophallic sclerite narrow, its posterior arms fused with lateral sclerites of ectophalic fold. Endophallic apodeme with both lateral lamellas and a medio-dorsal crest. Membrane of endophallic cavity smooth.
