Zumatrichia multisetosa Flint 1970

Zumatrichia multisetosa

This widely distributed species is easily recognized by the broad posterolateral lobe of the ninth segment which bears 5 to 10 elongate setae. The shape of the claspers is also rather distinctive as is the structure of the apical portion of the aedeagus.

This is one of the few species in the genus for which the immature stages are known. As pointed out previously, this is the only species in which the posterior of the frontoclypeus is rugose. Of course this characteristic may not prove to be specifically distinctive when the larvae of more species are known.

ADULT.—Length of forewing, 3 mm. Color fuscus marked with patches of greenish hairs. Male genitalia: Eighth sternum with posterolateral margin obliquely truncate. Ninth segment with anterolateral angle slightly produced and truncate; posterolateral lobe broad and bearing 5–10 stout setae. Lateral penis sheath broad, with a prominent ventral, subapical point. Clasper with a long, slender, apicolateral process, sometimes with its tip slightly bifid; midventrally fused and slightly produced. Aedeagus apically with a middorsal hoodlike process with its tip produced ventrally, beneath which are a pair of elongate spines, basoventrally with a pair of short, broad slightly bifid spines.

LARVA.—Length to 4 mm. Head brown; posterior half of frontoclypeal region rugose. Thoracic nota brown, points of articulation and margins darker. Abdominal tergites brown.

CASE.—Length 4 mm. by 2 mm. Silken with many imbedded sand grains; oval, slightly domed; circular openings at both ends, each rimmed with silk.
