description: Genus Calscirtus Otte, 1987   
 Calscirtus Otte in Otte et al., 1987: 444.   
 TYPE SPECIES. — Calscirtus amoa Otte, 1987 by original designation.   
 ILLUSTRATIONS. — Habitus: Fig. 13A, B. Male genitalia: Anso et al. 2016a: figs 12, 15. Calling song: Otte et al. 1987: fig. 45; Anso et al. 2016a: figs 16, 17.   
EMENDED DIAGNOSIS. — See Table 5. Body slender. General coloration light yellowish brown, uniform. Lateral ocelli wide, median ocellus tiny; ocelli set as an equilateral triangle; median ocellus subapical. Fastigium narrow. Maxillary palpi short; joint 5 truncate on almost whole length. Pronotum of regular width, slightly wider than long. Tympanal condition polymorphic (both inner and outer tympana present and equal in size, or inner tympanum lacking, or inner tympanum replaced by a shallow depression); three apical spurs. FI very high. TII with four apical spurs. FII inflated. TIII with five inner (sometimes only three) and five outer subapical spurs; three inner and three outer apical spurs; serrulation strong, irregular. Basitarsomeres III neither inflated, nor compressed; with two rows of dorsal spines. HWs truncate, slightly longer than FWs.  
 Male. FW well-developed with a complete stridulum; no tegminal gland. FW venation: chords long and hardly curved; chords 1 and 2 fused basally, but not fused to chord 3; mirror crossed by only one vein, transverse only in its basal, proximal part; diagonal bifurcate. Subgenital plate long, not acute, furrrowed apically. Male genitalia most often broadly symmetrical; pseudepiphallic sclerite broadly symmetrical; pseudepiphallic parameres either long and straight, or rounded; ectophallic fold symmetrical or not; endophallic membrane slightly concave, but true dorsal cavity lacking.   
 Female. FW venation numerous, with many longitudinal veins separated by numerous transverse veins delimiting square cells; apex of ovipositor with apical longitudinal striae, and strong, subapical teeth; subgenital plate with a very deep, median emargination, each lateral lobe bearing a distal glandular area covered with many short setae. Female genitalia: copulatory papilla small, with a more or less circular distal sclerite, prolonged ventrally by a sclerotized plate (see Desutter-Grandcolas 1997b: fig. 38).   
DISTRIBUTION. — Endemic to New Caledonia.  
 HABITAT. — Calscirtus species live in rainforest, dry forest or preforest vegetation, but have never been found in shrubland (Anso 2016, Anso et al. 2016a). They usually forage at night on plants: the females are often observed in the understorey, while males usually sing higher on trees. By day, they have been found several times sheltering in hollow twigs (Desutter-Grandcolas 1997b).
