Zumatrichia strobilina

This species is closely related to the preceding from which it differs in the twisted, spiniferous basodorsal process of the clasper, the narrower lateral penis sheaths, and in the spines of the aedeagus.

ADULT.—Length of forewing, 4 mm. Coloration typical pattern of grayish green and fuscus. Male genitalia: Eighth sternum without processes; with a deep, broad apicomesal excision. Ninth segment with anterolateral angle broadly rounded; posterolateral lobe slender, bearing a large, apical seta. Lateral penis sheath elongate, narrow, rounded, about 4 times as long as broad, with a ventral tooth slightly beyond midlength; in ventral aspect with apical portion sinuate. Clasper with a heavy, twisted, basodorsal process bearing spiniform teeth on apical portion; ventral lobe in lateral aspect with a strong, subapical, dorsal hook, in ventral aspect with posterior margin broadly conical. Aedeagus apically with lateral plates united dorsally and prolonged into a spiniform process, a pair of long spines dorsally, and a pair of short spines ventrally.

MATERIAL.—Holotype, male. COSTA RICA: CARTAGO: 3 miles west of Turrialba, 18–21 June 1967, Flint and Ortiz. USNM Type 70908. Paratype: Same data, 1 .
