Antitrygodes pseudagrata sp. n. 

14, 15mm, 14mm. This species is externally similar to A. agrata Felder (Moluccas), A. restricta Prout stat. n. from Sulawesi (slide 18401) and A. vicina Thierry-Mieg stat. rev. (N.E. Himalaya), but differs markedly in features of the male genitalia. The socii are broad, short, bifid in agrata, but twice as long, narrow, club-like in pseudagrata. The valves in pseudagrata have an additional, double, central spur, not seen in other taxa of the group; the distal digitate process is only half as large as that of agrata. A. restricta has the socii narrow, but tapering, acute; the distal processes of the valves are outcurved. In vicina the socii are fused and the valves and cerata of the eighth sternite are bilaterally asymmetric. Material from Luzon (slide 18400) is probably referable to pseudagrata, but the socii are somewhat shorter, broader; the cerata are also shorter. Bornean material is worn, so a male of A. vicina is illustrated below. The complex is distinguished from A. divisaria on the diagnosis for that species above.
