Carapezzaptera auritomentosa nov.sp. ( Figs 1-5 )

H o l o t y p e: ♁, labelled: Sri Lanka mer.centr. / Matara distr. / 4.-8.12 1995 / 3km NW Kotapola / let. S. Becvar // (CEHI). This specimen is designated as holotype and provided with type label.

D e s c r i p t i o n:

Apterous male; coloration reddish brown with golden-yellowish tufts of pilosity on head, thorax and abdomen, antennae and legs with erect yellowish hairs.

Head: Slightly wider than long (1.0 / 1.025); genae produced over clypeus contiguous in front; antenniferous lobes with blunt apices, as long as genae; antennae cylindrical 2.98 times as long as width of head (3.05 / 1.025), length of antennal segments I / II / III / IV = 1.10 / 0.75 / 0.80 / 0.40; oval eyes inserted in head, postocular lobes strongly converging posteriorly to constricted neck; rostrum arising from a slit-like atrium, shorter than head; vertex carinate.

Pronotum: Wider than long (1.45 / 0.95), collar ring-like as thick as femur of anterior legs; disk with two elevated oval callosities separated by a median furrow; lateral margins converging anteriorly, posterior margin slightly convex delimited by two transverse carinae.

Mesonotum: Consisting of two inclined oval callosities separated at middle by a deep cleft anteriorly, followed by a Y-shaped ridge which extends posteriorly.

Metanotum and mtg I+II. Fused together, each marked by two oval callosities lateral of median elevated ridge delimited laterally by a raised carinate sclerite with lateral margins converging anteriorly.

Abdomen: Tergal plate about twice as long as wide with a strong longitudinal median ridge, lateral margins carinate and elevated, deltg II+III not fused, III-VIII separated by sutures; tergite VII medially raised for the reception of the pygophore; deltg VII consisting of two layers separated by horizontal furrows forming the posterior lobes; spiracle II plainly visible on a conical tubercle produced from posterolateral angle of mtgII, spiracles III-VII are placed ventrally on distinct tubercles which are partly discernible in dorsal view, spiracles VIII terminal on ptg VIII, pygophore of conical shape, truncate posteriorly.

M e a s u r e m e n t s: Length 7.70 mm; length of antennae 3.05; width of mesonotum 1.65; abdomen widest across suture mtg II-III 2.35; across tergite IV 2.00, V 2.05, VI 2.15.

E t y m o l o g y: The specific epithet refers to the golden-yellowish pilosity of its body and is the Latin adjective composed of "aureus" (meaning golden) and "tomentous" (meaning beset with a mesh of fine hairs).
