Trichadenotecnum kalibiruense n.sp.

Figs. 34–39

Material examined. HOLOTYPE ♂, Sumatra: SE, Way Kambas National Park , Kali Biru , 4°58'S 105°52'E, mixed secondary forest , 20 m, 2.VII.1997, ESK ( ZMB) .

Female unknown.

Male

Colouration (c. 4 years in alcohol). Generally brown, with the following exceptions; ocelli pale; eyes and central area between ocelli black; basal ¼ of anteclypeus dark brown, otherwise pale. Fore wing with scattered brown clouds as in Fig. 34. Hind wing suffused brown (Fig. 35).

Morphology. IO:D 2.75. Fore wing venation as in Fig. 34. Hypandrium (Fig. 36) symmetrical: distal row of short sharp teeth each side, a large stout spine at base of each row, and a larger central pointed projection. Phallosome (Fig. 37) an open frame, bilobed anteriorly. Epiproct shallow trapezoidal (Fig. 38). Paraproct (Fig. 39) with basal sclerotized hook and field of about 19 trichobothria.

Dimensions. B 1.5; FW 1.9; HW 1.38; F 0.33; T 0.73; t 1 0.23; t 2 0.08; t 1 /t 2 2.88; Ct 17 (t 1) 2 (t 2); f 1 0.23; f 2 0.22; f 1 /f 2 1.04.

Remarks. In wing pattern and genitalia features, T. kalibiruense differs from any Oriental species of Trichadenotecnum described previously. The hypandrium is similar to those of T. masoni New from Nepal and T. bromoense Endang et al. from Mt Bromo, East Java. All three have a lateral serration of the apical lobe and a single large central projection. Trichadenotecnum masoni and T. bromoense, however, lack the pair of large symmetrical spines and a row of four teeth medially. Moreover, the apical spine of the paraproct in T. kalibiruense is longer and more sharply curved than those of T. masoni and T. bromoense. Trichadenotecnum bromoense was referred to Yoshizawa’s (2001) spiniserrulum group, and the basal paraproct process of the male of T. kalibiruense implies a similar position.
