Trichadenotecnum krucilensis Endang et al., 2002: 165.

Material examined. Sumatra: SW, BBSNP, Lombok, 4°44'S 103°57'E, cinnamon, 540 m, 1♂, 26.VII.1997, ESK .

Remarks, This species was described from male material collected at moderate elevation (750 m) in East Java in December 1991. The female is unknown. The above Sumatran specimen agrees with specimens of T. krucilense from Java in wing pattern and features of the genitalia. However, the Sumatran male’s hypandrium differs from that of the type in that it has four lateroanterior spikes (Fig. 13) instead of three. This difference might represent intraspecific variation but, alternatively, the individuals might represent distinct species. Despite this difference, we place this specimen in T. krucilense and figure its hypandrium in order to facilitate further appraisal.
