Drepanosticta new species – Dow & Ngiam, 2012: 11
Material examined. — Holotype: male (SAR11_12_PST22), Malaysia, Sarawak, Kapit Division , Hose Mountains, Gunung Kajang area, at side of stream at 900–1000 m, 6 Apr.2011, coll. RAD, to be deposited in RMNH.
Diagnosis. — The male of T. kajang is readily distinguished from other species of Telosticta except for T. berawan , T. dayak , T. paruatia and T. ulubaram by the form of its superior anal appendage, with a distinct, deep, ‘V’ shaped cleft in the tip, easily visible in lateral view. It is easily distinguished from T. paruatia by having a shorter interior projection on the superior appendage, much shorter than the distance from S10 to the base of the projection. It is distinguished from T. ulubaram by the depth of the inner groove above the cleft in the tip of the superior appendages as seen in dorsal view, very deep in T. ulubaram with the bases of the two arms appearing as large rounded knobs in dorsal view, compared to shallow in T. kajang . It is distinguished from T. dayak by having the arms of the cleft in the tip of the superior anal appendage of unequal length in typical lateral view. It is separated from T. berawan by having a slightly longer and less basal interior projection on the superior anal appendages, the shape of the cleft in the tip of the superior appendages and pale dorsal markings on abdominal segment 9.
Etymology. — kajang , a noun in apposition. Named for the area of the type locality.
Description of holotype male. — Head: Labium pale. Basal 2/3 of labrum blue, black along free margin.Anteclypeus blue, postclypeus shining black. Mandible bases blue in corner by clypeus, black below. Vertex and frons bronzy black, occiput shining black. Ratio of width of compound eye to width of vertex measured at level of lateral ocelli ca 9/10. Transverse occipital carina with lateral extremities angulated and prominent. Ocelli whitish. Antenna with top of scape and basal 3/4 of pedicel greyish, rest black, flagella missing.
Thorax: Prothorax, largely creamy white except in upper rear of propleuron, a central black diamond shape mark on anterior lobe, rear half of middle pronotal lobe and whole posterior pronotal lobe, where black, except the lateral processes which are grey. Lateral pronotal processes well formed and long ( Fig. 9C View Fig ) with the tip falling short of the level of the lower margin of the propleuron. Synthorax: Mesepisternum bronzy black, with a pair pale blue antehumeral stripes, occupying ca 2/3 of the length ( Fig. 10D View Fig ). Antealar triangles black. Mesepimeron bronzy black. Metepisternum largely occupied by a pale band, becoming blue towards wing bases, with a bronzy black wedge below, this extending from the wing bases to the metinfraepisternum. Metepimeron mostly pale, narrowly black below the metepleural suture. Venter of synthorax pale. Legs: each with coxa and trochanter cream, femur dirty cream with a dark stripes along extensor and flexor surfaces, black above joint. Tibia black immediately below femur, then mostly pale, black just above tarsus, which is mostly pale but dark at joints and with pale brown claws. Wings: 14 (left) to 15 (right) Px in Fw, 14 Px in Hw. Vein ab present. R 4 arising distal to subnodus in both wings, IR 3 joined to it by a short stalk, ab present in all wings. Pterostigma approximately trapezoidal with costal side shorter than anal side, and proximal side slightly shorter than distal side, black with white border, covering slightly more than one underlying cell.

Abdomen: Largely very dark brown to black with some paler lateral markings. S1 mostly very dark brown, dirty cream at sides basally. S2 with a pale basal annulus, broadly interrupted dorsally, laterally this extending to the posterior carina as a pale wedge, otherwise dark brown. S3–7 brown with a narrow, poorly developed pale basal annulus interrupted dorsally, becoming less distinct on successive segments; each segment becoming darker apically. S8–10 black with a large sub rectangular pale blue dorsal marking on S8 and another on S9 ( Fig. 11D, J View Fig ). Appendages ( Figs. 12C View Fig , 13D View Fig , 14C View Fig ) mostly black. Superior appendage nearly 3 times the length of S10, with interior projection at ca 1/3 length directed inwards and downwards so clearly visible in lateral view, but with a sharp upward and slightly distally directed spur. Dorsal projection barely developed as a rounded inwards directed swelling, not apparent in lateral view. Expanded dorsal-ventrally and slightly laterally in distal ca 1/3, with a narrow ‘V’ shaped cleft at tip, with the lower arm of the cleft just shorter than the upper, but flattened and gently curved in profile, the upper branch robust and blunt ended, on interior side a shallow groove above the cleft between the bases of the two arms. Inferior appendage almost as long as superior, stem moderately robust, scoop expanded and up- and out-turned at tip, spine robust and directed inwards, upwards and to rear.
Measurements (mm): Abdomen without anal appendages 40, superior appendage ca 1.25, Hw 23.5.
Female. — Unknown
Remarks. — See under T. berawan for a discussion of the similarity of the two species.
Biological notes. — The unique male of T. kajang was found perched high and slightly back from a steep stream in disturbed forest at 900–1000 m.
Distribution. — Known only from the Gunung Kajang area of the Hose Mountains in Sarawak’s Kapit division (Fig. 21).
