Diagnosis. Plectropsyche wallacei  n. sp. can be separated from the other species of the genus by the cone-shaped apical segment of each inferior appendage in posteroventral view, by the elongate shape of the setose warts of segment X in lateral view, and by the long truncate posterolateral lobe on each side of segment IX tapering dorsally in lateral view ( Fig. 4View FIGURE 4).

Adult male. Length of each forewing 6–7 mm (n = 8). Color of pinned specimen light brown, without any marked pattern. Male genitalia: Abdominal segment IX in dorsal view produced into two widely separated lobes, each bearing three or more long setae; in lateral view posterolateral margin produced into truncate lobe tapering dorsally, with row of long setae. Segment X in dorsal view with posterior margin slightly concave at center, flanked on each side by large, spinose lobe, each with lateral, setose wart; in lateral view slightly produced posterad with preapical, elongate setose wart and short, setose lobe apically. Inferior appendages in posteroventral view nearly straight, each basal segment with scoop-like basal portion, slightly narrowed beyond base and widened again near apex, bearing several long setae near apex; apical segment tapering to apex, less than one-half length of basal segment. Phallus in dorsal view gradually constricted apically to narrow neck, beyond which apical region enlarged suddenly to form pair of separated, scoop-like apicolateral valves.

Adult female. Length of each forewing 6–7 mm (n = 5). Color in alcohol light brown. Female genitalia in ventral view with segment IX+X with complex internal membranous structures with vaginal opening at center and with two or more rectangular plates and with pair of rounded bag-like structures situated basally; segment X with pair of lateral, setose warts, each wart with pair of finger-like lobes underneath cluster of hair-like spines; in lateral view with three pairs of finger-like lobes setose basally, in dorsal aspect fused segment IX+X with dorsal cap covered by two large plates bearing minute setae not divided in center, inferior appendage receptacles large, situated at midlength of segment
