Diagnosis. Plectropsyche hoogstraali Ross is distinguished from the other species of the genus by the middle incision on the apical border of segment X being bordered by low lateral lobes, by the two rounded lateral warts of segment X that are visible in lateral view, and by the long, cylindrical apical segment of each inferior appendage in posteroventral view.
Adult Male: Length of each forewing 6–8 mm (n = 12). Color of pinned specimens fuscous, in alcohol brown without any marked pattern. Male genitalia: Abdominal segment IX in dorsal view produced into two widely divergent lobes, each bearing three or more long setae; in lateral view posterolateral margin produced into long, tapering truncate lobe, directed dorsocaudad, with row of long setae on each dorsal and ventral edge. Segment X in dorsal view composed of tapering, central lobe incised mesally to form pair of angulate points, flanked on each side by low lateral lobe and setose wart; in lateral view apex slightly truncate and sinuous, with two preapical, almost spherical, setose warts. Inferior appendages in posteroventral view nearly straight, each with basal segment with scoop-like basal portion, slightly narrowed beyond base and widened again near apex, bearing several long setae near apex; apical segment cylindrical, almost half length of basal segment. Phallus in dorsal view gradually constricted apically to narrow neck, apical region enlarged suddenly to form pair of scoop-like, membranous, apicolateral valves.
Adult Female: Length of forewing 5.8–8.0 mm (n = 9). Color in alcohol dark brown. Female genitalia: Ventral view of segment IX with complex, internal, membranous structures including vaginal opening at center with two or more rectangular plates, and pair of rounded bag-like structures situated anteriorly; lateral view of segment IX with rounded posterolateral lobe on each side overhanding receptacle for male inferior appendage. Ventral view of segment X with pair of lateral setose warts, each wart with pair of short, stout 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 forming dorsal cap composed of two large plates bearing minute setae and divided in center, inferior appendage receptacles large, situated at midlength of segment.
