Type material. Female holotype: Malaysia. Sabah State, Borneo I., Trus Madi Mt, ~ 1000 m, partly primary/ partly secondary forest, on leaf of bush, at night, 13–25.V.2007, A. Gorochov ( ZIN). Paratypes (3♀): Malaysia, Sabah State, [Borneo I.], Sabah, nr. Long Pa Sia ( West ), c. 1020 m, 25.XI.1987, Mal [aise] trap 2, RMNH87, C. v. Achterberg: 1♀ ( RMNH); 1♀ (MNHN-EO-ENSIF3510) .

Type locality. Malaysia, Borneo , Trus Madi Mount .

Other material examined. Malaysia. Sabah State, [Borneo I.], Sabah, nr. Long Pa Sia ( West ), c. 1020 m, 25.XI.1987, Mal [aise] trap 2, RMNH87, C. v. Achterberg: 2 juveniles ( RMNH); 1 juvenile ( MNHN) .

Etymology. Named after very spotted (variegate) colouration.

Distribution. Malaysia, northern part of Borneo.

Diagnosis. The new species is very close to C. pelagus . It differs from all the other similar congeners in the characteristic coloration: face almost uniformly yellow, pronotum with two dark bands on each lateral lobe, legs strongly spotted, and hind femora with very dark apical part.

Description. Female: Coloration of body yellowish ( Fig. 58A–B ) with following ornament: head ( Figs 6N , 58C–E ) with yellow face, light brown narrow stripe along clypeal suture, several brown spots on dorsum and behind eyes, light brown scape and palpi, slightly darker proximal part of antennal flagellum having several brown spots, and brown middle and distal parts of this flagellum; pronotum with two dark brown longitudinal bands on lateral lobes (wider upper band, and narrower and shorter lower band situated along anterior 2/3 of ventral edge of these lobes) and with several brown spots on median part of disk ( Fig. 58D ); tegmina ( Fig. 12I ) brown (almost dark brown) with three whitish spots (basal spot, proximal humeral stripe fused with previous spot, and distal humeral spot), one of longitudinal vein in dorsal field also whitish, crossveins in this field light brown, some branches of Sc and crossveins between them whitish, and R and stock of Sc as well as crossveins between them reddish brown; exposed part of hind wings dark brown with light brown venation; legs with numerous distinct brown spots, very dark brown apical part of hind femora, dark brown base and ventral surface of hind tibiae as well as very distinct dark brown spots on rest of these tibiae and on hind tarsi; abdomen with dark brown tergites having lighter spots and with small dark spots on cerci. Structure of body similar to that of female of C. reticulatus , dorsal tegminal field with 10 moderately convex longitudinal veins, genital plate intermediate between those of C. reticulatus and C. borneoe in shape of its apical part, and hind femur 1.3 times as long as ovipositor. Apex of ovipositor with both dorsal and ventral edges denticulate ( Fig. 13S ).

Female genitalia ( Fig. 15I ): Copulatory papilla diamond-shaped with wide baso-lateral sclerites; apex barely rounded and sclerotized, only slightly folded ventrally.

Male: Unknown.

Juvenile: Coloration pattern of head and legs close to that of adults; body light brown mottled with dark brown.

Measurements. Length in mm. Body 16.5; body with wings 21; pronotum 2.5; tegmina 12.5; hind femora 13.5; ovipositor 10.5.

Habitat and life history traits. Unknown.

Behavior. Unknown.
