Morphology. IO:D 1.18; Ct 23 (t1), 2 (t2). Fore wing (Fig. 32) pterostigma long, veins Rs and M connected by long crossvein, areola postica tall. Hypandrium (Fig. 33) simple with lateral and apical sclerotised bar. Phallosome (Fig. 33): parameres separate, very large posteriorly, with long spine. Epiproct and paraproct (Fig. 34): paraproct with field of about 26 trichobothria.

Dimensions. B 1.95; FW 2.94; HW 2.06; F 0.63; T 1.3; t1 0.10; t2 0.42; t1/t2 42; f1 0.69; f2 1.19; f1/f2 1.19. Holotype male: INDONESIA, SUMATRA, West, Kerinci Seblat National Park, Birun, dead leaves, 240m, 18.I.1997, ESK.

Remarks. On fore wing venation the specimen above is referred to Anomaloblaste, in having a long pterostigma, long crossvein and five-sided tall areola postica. The fore wings of Amphigerontia and Mecampsis also have a crossvein, but this is shorter than that of the above specimen. The shape of the areola postica also differs. The parameres of the phallosome resemble those of Amphigerontia bifasciata (Latreille), A. anchonae Li and A. lhasana Li & Yang, in each having a posterior hook, but the hypandrium differs from those three species; it is simple and lacks the accessory sclerite.

This species is named for Sudaryanto, in appreciation of his help to ESK during her field work in Sumatra.
