Zumatrichia antilliensis Flint, 1968b, p. 34.

This species, which is often very abundant on the Lesser Antillean islands, is very similar to the preceding species, Z. echinata Flint. From this species it differs in having more slender apicolateral lobes of the clasper and in the structure of the apical portion of the aedeagus.

ADULT.—Length of forewing, 3–3.5 mm. Coloration typical pattern of grayish green and fuscus. Male genitalia: Eighth sternum without processes, rather broad, divided ventromesally. Ninth segment with anterolateral angle produced into a narrow lobe; posterolateral lobe slender with a single apical seta. Lateral penis sheath elongate, ovoid, about 1½ times as long as broad, with a midventral tooth. Clasper with a long, slender, slightly sinuate, basodorsal process; ventral lobe elongate, with digitate apicolateral lobes. Aedeagus apically with a middorsal process widened basally, a pair of lateral spines, and an appressed, hooked, pair of midventral processes.

LARVA.—Length to 3 mm. Head brown; without rugosity, tentorial pits rather well marked. Thoracic nota and legs, brown, points of articulation and posterior margins of nota darker. Abdominal tergites brown.

CASE.—Length 4 mm. by 1.5 mm. Silken; oval in outline, slightly domed; with circular anterior and posterior openings.
