Tolpia hainanensis Fibiger , new species

( Plate 9 , figure 6; male genit. plate 19, figure 1)

Material examined. Holotype: male, China, Prov. Hainan, Yinggeling, Ma Hou Ling , camp 2, 960 m, 18º59’04 N, 109º24’14 E, leg. & coll. R. C. Kendrick, genit. prep. 6166 M. Fibiger.

Diagnosis.Imago (external). Wingspan: 14 mm.

Crosslines: all lines brown, indistinct, with a black costal spot, terminal line marked by black interneural spots.

Reniform stigma: indistinct, almost invisible.

Underside: unicolorous brown.

Hind-legs: with prominent, long scent brush.

Abdomen: brown, with black crest on first segment, male with long black to brown anal tuft.

Male genitalia. Saccus: short, rounded at tip.

Vinculum: short.

Tegumen: extremely long.

Fultura superior: left side sclerotised, fused with tegumen, forming a small, broad-based, triangular process.

Tergite and sternite: indistinct.

Sacculus: indistinct.

Clavus: right side with heavily sclerotised, quadrangular, platelike processes, with setose crest (apo.).

Ampulla: base dorsally on right side with three processes, middle fingerlike; on left side with four processes, outer-dorsal rounded (apo.); apically slightly asymmetrical, golf clublike, apically smoothly rounded [right cucullus broken off, probably similar to left, judging from sister-species, see T. sikkimi Fibiger, 2007 ].

Pollex: basally setose; right side small; right side with humplike process (apo.).

Digitus: curved, pointed apically, left one short, right one very long.

Juxta-anellus plate: higher than wide, with hole for phallus [here attached to phallus].

Phallus: broadest by ductus ejaculatorius, coiled clockwise, S shaped from middle, tapered towards tip, coecum short and broad.

Bionomics. Type-species was recorded in primary forest, with canopy at 25 m.

Differential diagnosis. Male genitalia of T. hainanensis show close relationship with those of T. sikkimi Fibiger, 2007 but differ from that in:

- clavus on right side quadrangular, with setose crest;

- pollex on right side larger, humplike;

- dorsal base of cucullus with three processes; left side with four processes;

- coecum less pointed;

- phallus more curved, more prominent S shaped.

Distribition. T. hainanensis is only known from type specimen from South China, Hainan Island .
