Fig. 24

Diagnosis. Zumatrichia flinti is placed in the galtena group of Flint (1970) based on the presence of a basodorsal process from the inferior appendages. The new species, along with Z. diamphidia Flint and Z. attenuata Flint , has a tripartite inferior appendage and appears to be most similar to Z. attenuata . Zumatrichia flinti differs in the shape of the basodorsal process of the inferior appendage, which is apically straight in Z. flinti , but sharply angled in Z. attenuata . As well, the subapical process from the basodorsal process projects dorsally in Z. attenuata and ventrally in Zumatrichia flinti .

Male. Length 3.0– 3.2 mm. Head without modification, antennae 18 segmented with enlarged scape, body and unmodified wings brown in alcohol. Abdominal segment VII annular with posteroventral mesal process. Segment VIII in lateral view truncate posteroventrally, tapering dorsally; in dorsal view narrow, concave posteromesally; ventrally with wide mesal incision on posterior margin. Segment IX generally quadrate in lateral view, narrowing anteriorly, posterior margin with thin lobe, laterally with elongate setal-bearing process; dorsally emarginate anteriorly and posteriorly, posterior margins sclerotized. Segment X rectanguloid in lateral aspect; in dorsal view square, with posterior margin tapered. Inferior appendages tripartite, dorsalmost process angled basally then thin and elongate, subapically with ventral process, medial process thin and acute distally, ventralmost portion rectangular, rounded distally; in ventral view this ventralmost process is truncate posteriorly with numerous setae, small medial notch. Penile sheath with subapical point in lateral view; phallus with medial ring-like process, basally with pair of thin basal spines, apically divided into three rods, dorsalmost shelflike and shorter than lower pair, medial rod thin and spinelike, ventralmost rod narrow to upturned apex; in dorsal view, phallus apex with elongate central rod with three short basal spines.

Female. Unknown.

Type material. Holotype, male— Panama, Bocas del Toro Province, Quebrada Rambala, near Rambala Jungle Lodge , 3.74 km SSE Rambala, 8.91627°N and 82.15469°W, 120 m, Malaise trap, February 6–12, 2017 . Paratype. tributary to Quebrada Rambala , above waterfall, 134 m, March 28, 2015, B. Armitage, 1 male ( SCH).

Etymology. We take great pleasure in naming this species for our colleague Dr. Oliver S. Flint, Jr., Smithsonian Institution, in recognition of his lifetime of work on the Trichoptera of the Neotropics.
