Telosticta santubong View in CoL , new species
( Figs. 3F View Fig , 4G View Fig , 5E, K View Fig , 6E View Fig , 7E View Fig , 8E View Fig , 22 View Fig )
Material examined. — Holotype: male (SAR05_PST65), Malaysia, Sarawak, Kuching division, Damai Peninsular , Gunung Santubong National Park, small streams on Gunung Santubong, 100–400 m, 28 May 2005, coll. RAD, RMNH.
Paratypes (all from same location and date as holotype, all coll. RAD): 6 males (SAR05_PST59–64) . Paratypes in RMNH and coll. RAD.
Diagnosis. — Readily distinguished from all other species of Telosticta except T. dupophila and T. serapi by its very short antehumeral stripes and short lateral processes of the posterior pronotal lobe. Separated from T. dupophila and T. serapi by having the interior projection of the superior anal appendage reduced to a ridge bearing a clump of long setae.
Etymology. — santubong , a noun in apposition. Named for the type locality, Gunung Santubong in the National Park of the same name.
Description of holotype male. — Head: Labium pale cream except for end hooks of labial palps, which are brown. Labrum pale blue except narrowly along free margin, where shining black. Anteclypeus pale blue, postclypeus shining black. Mandible bases pale blue in corner by clypeus, black otherwise. Vertex and frons shining metallic greenish-black, occiput shining black. Ratio of width of compound eye to width of vertex measured at level of lateral ocelli just over 9/10. Lateral extremities of transverse occipital carina not angulated. Ocelli yellowish. Antennae with scape greyish, pedicel cream, brown at top, rest black.
Thorax: Prothorax with propleuron pale cream, except to rear where obscurely mottled with dark brown. Pronotum with anterior lobe pale blue dorsally to cream laterally, except for a small black transverse stripe placed centrally just behind the anterior carina, median lobe pale blue dorsally to cream laterally, except at rear, where narrowly black. Posterior lobe black, hind margin simple, lateral process ( Fig. 3F View Fig ) short, reaching ca halfway to the lower margin of the propleuron. Synthorax: Mesepisternum black, with a pair very short pale blue antehumeral stripes occupying ca 1/4 of the length (as in Fig. 4G View Fig which shows a paratype).Antealar triangles black, but mid-dorsal carina pale between them. Mesepimeron largely bronzy black. Metepisternum with a pale blue stripe in upper part, extending to lower margin of spiracle, tapering towards antealar carina and extending slightly above the mesepleural suture, otherwise brown. Metepimeron cream, obscurely brown around mid-length below metepleural suture. Venter of synthorax pale. Legs: each with coxa and trochanter cream, femur cream, with obscure dark markings and a black stripe along extensor surface, black above tibia. Tibia cream, black below femur and with black stripes on flexor surface. Tarsi cream, black towards claws, which are brown. Wings: 13 Px in Fw, 11 Px in Hw. Arculus slightly distal to Ax2. Vein ab present except in right Hw. R 4 arising distal to subnodus, IR 3 joined to it by a short stalk. Pterostigma trapezoidal, pale brown with white border, covering slightly more than one underlying cell.
Abdomen: Dark brown above, paler to sides. S1 cream, brown behind posterior carina. S2 with a pale basal annulus, interrupted dorsally, laterally this extending towards, but not quite reaching, the posterior carina as a pale wedge. S3–S7 with a narrow pale basal annulus, interrupted dorsally and becoming less distinct on successive segments. S8 very dark brown dorsally, cream laterally. S9 largely pale blue dorsally, obscurely cream and brown laterally. S10 obscurely pale mottled with brown over much of dorsum, black to rear, pale to sides. In dorsal view abdomen expanding evenly laterally from S8 to base of S10 ( Fig. 5E, K View Fig ). Anal appendages ( Figs. 6E View Fig , 7E View Fig , 8E View Fig ) largely dark brown and black. Superior appendage ca 2.5 times as long as S10, interior projection reduced to an inwardly and upwardly oriented ridge, reaching its highest point at just before half the length of the appendage, clear visible in lateral view, then abruptly running down, a distinctive clump of long setae originating on and around the ridge and directed mostly inwards and upwards ( Fig. 6E View Fig ). Dorsal projection barely developed, just visible as a bump in dorsal-lateral view. Appendage down curved in rear half, suddenly straightening at just before rounded tip ( Fig. 7E View Fig ). Inferior appendage with stem very robust, broad in ventral view, scoop only slightly expanded, rounded, upturned terminally and with its concave face orientated somewhat inwardly, spine directed inwards and rearwards ( Fig. 8E View Fig ).
Measurements (mm): Abdomen without anal appendages 37, superior anal appendages ca 1.25, Hw 21.
Female. — Unknown
Variation in paratypes. — In two of the paratypes the interior projection of the superior appendage is produced into a sharp point at its highest point. In some of the paratypes the dorsal projection is slightly more apparent than in the holotype and the pale marks on the dorsum of S10 are reduced in some.
Measurements (mm): Abdomen without anal appendages 35–37.5, Hw 19.5–22. Wings with 11–13 Px in Fw, 9–11 Px in Hw.
Biological notes. — Males were found at small streams in steep terrain in mixed dipterocarp forest.
Distribution. — T. santubong is known only from the mountain of the same name, on the Damai peninsular in west Sarawak ( Fig. 22 View Fig ).
