Trichadenotecnum adika Endang, Thornton & New

( Figs 1H , 10 )

Trichadenotecnum adika Endang, Thornton & New, 2002: 166 .

Specimen examined. 1 male, Singapore, See Soon , Rifle Range Swamp Forest, beating, 18.xii.1987, CL ( MHNG) .

Remarks. The specimen examined here agrees well with T. adika in male genital structures. In contrast, it is significantly smaller (forewing length 1.8 mm) than the male holotype of T. adika from Java (forewing length 2.6 mm). The small form could provisionally be interpreted as a lowland form (cf. Bergmann's rule): all Indonesian specimens were collected between 700 and 1460 m ( Endang et al., 2002; Endang & New, 2005). Therefore, we identified the above specimen as T. adika . This is the first record of this species from the region.
