Trichadenotecnum malayense New

( Figs 1M , 16 , 17 )

Trichadenotecnum malayense New, 1975: 257 ; New & Lee, 1992: 156; Endang, Thornton & New, 2002: 156; Endang & New, 2005: 24.

Specimens examined. [ Malaysia] 1 female, Fraser's Hill, Pahang, 5.iii.2003, KY (UKM); 2 males (KY334), Endau Rompin National Park , Johor, 7.vii.2003, KY ( UKM & SEHU) ; 1 female, University Forest of UKM, Bangi , Selangor, 6.iii.2005, NT ( SEHU) .

Remarks. This species was originally described only on female specimens from Malaysia, and the male of this species was later identified from Sumatra, Indonesia by Endang & New (2005). The female genital structures examined here ( Fig. 17 ) are in complete agreement with those described by New (1975), and male terminal structures of the specimens examined here ( Fig. 16 ) agree very well with the description given by Endang & New (2005) except for the difference of the phallosome [illustrated as if it were closed in Endang & New (2005: fig. 16) whereas it is widely opened in the presently examined specimen ( Fig. 16C )]. Based on the densely spotted forewings, the presence of a basal process on the male paraproct, and the short ventral valve of the gonapophyses, assignment of this species to the spiniserrulum group is unquestioned ( Yoshizawa, 2001). However, male and female terminal structures are quite distinct from the other species of this group. Complete absence of the posterior lobe of the external valve of gonapophyses may indicate close affinity between T. malayense and T. pardus , treated above, or T. godavarense New, 1971 (see Yoshizawa et al., 2007 for taxonomic status of the latter species).
