MATERIAL. Holotype – ♂, Indonesia: Sumatra I., Aceh Prov. near border with

North Sumatra Prov., environs of Ketambe Vill. on Alas River in Gunung Leuser

National Park, 3º41–42ʹN, 97º38–39ʹE, 300–500 m, primary forest, on leaf of bush at night, 15–24.IV 2018, A. Gorochov, M. Berezin, I. Kamskov, E. Tkatsheva. Paratypes: 2 ♂, 2 ♀, same data.

DESCRIPTION. Male (holotype). Coloration ( Fig. 62 ) almost uniformly yellowish (light greenish in living condition) with brown eyes, small and numerous light brown to dark brown spots on antennal flagellum, greyish brown apices of palpi and dots on both sides of femoral apices, darkened spines and spinules (including spurs)

on tibiae as well as areas on tympanal membranes and on distal part of hind tibia,

and almost blackish small marks on subapical segment of tarsi. Wings insignificantly shortened: tegmina narrow, reaching apices of hind femora (i.e. distinctly protruding beyond abdominal apex), and with apical parts approximately as in C. variegata ;

hind wings reaching tegminal apices but not protruding beyond them. Last tergite slightly narrower than in this species, somewhat narrowing to apex, with wide and short posterolateral lobe having almost truncated posterior edge with small (shallow)

posteromedian notch; these edge and notch poorly distinct, because last tergite partly fused with large but not long epiproct; this epiproct consisting of a pair of lateral lobes having rather complicated shape including two obtuse lobules (dorsal and ventral); cercus arcuately curved upwards and forwards in rest position, with somewhat thickened basal part and almost lamellar more distal portion, with 2 short lobules (at base and in middle part of cercus), and with apical part rounded in profile

( Figs 63, 64 , 82, 83 ); genital plate with short styles and very small posteromedian notch between them ( Figs 81, 83 ); genitalia with median sclerotized structure as in

Figs 65, 66 .

Variations. Paratypes with darkened marks slightly lighter, and their abdominal apex somewhat deformed during drying; in one male, hind wings barely protruding beyond tegminal apices, and median sclerite of genitalia with desclerotized proximal part.

Female. General appearance as in males, but tegminal stridulatory apparatus undeveloped, and last tergite, epiproct and cerci unspecialized; genital plate of simple shape and with small posteromedian notch ( Fig. 84 ); ovipositor as in Fig. 67 .

MEASUREMENTS. Length (in mm). Body: ♂ 10–10.5, ♀ 8.5–13; body with wings: ♂ 16–17, ♀ 17–18.5; pronotum: ♂ 4.3–4.5, ♀ 4–4.2; tegmina: ♂ 12.5–13, ♀

13.5–14; hind femora: ♂ 12.5–13.5, ♀ 13–13.5; ovipositor 9–9.2.

COMPARISON. The new species is most similar to C. abbreviata comb. n.

from South Sumatra. It differs from the latter species in the male epiproct having obtuse (not almost spine-like) ventral lobules of lateral lobes, male cercus with the apical part rounded (not angularly bifurcated) in profile, and female genital plate with a small apical notch (vs. without apical notch); from C.? nebulosa comb. n.

( Indonesia: unknown locality) having the male cerci more or less similar in shape,

the new species is distinguished by these cerci more arcuately (not almost angularly)

curved in profile, and by the lateral lobes of male epiproct not hooked.

ETYMOLOGY. Name of this species is the Latin word “modesta” (modest,

simple), because its body coloration is rather uniform.
