Diagnosis. Neotrichia starki belongs to a large cluster of Neotropical species with a characteristic elongate process from segment IX, including N. delgadeza Harris and Davenport , N. napoensis Harris and Davenport , N. tompa Olah and Johanson , and N. filifera Flint. The new species is readily identified by the structure of the inferior appendages and the greatly reduced tenth tergum.

Male. Length 1.3 mm, 18 antennal segments, brown in alcohol. Abdominal segment VIII annular. Segment IX rounded anteriorly, sinuate posteriorly with submesal triangular projection, notched dorsally giving rise to elongate sinuate rod; in ventral view narrow posteriorly with short lateral processes, incised anteriorly; in dorsal view narrow with pair of elongate sinuate rods. Segment X in lateral view short and wide; dorsally short and inconspicuous, truncate mesally and membranous. Subgenital plate in lateral view triangular, wide basally, gradually tapering to acute apex, which bears a stout seta; in dorsal view wide basally, abruptly narrowing distally to truncate apex, pair of setae laterally. Bracteoles elongate, widening posteriorly to rounded apex. Inferior appendages nearly parallel-sided basally, narrowing distally to rounded apex; in ventral view rectanguloid, basally incised along inner margin. Phallus in dorsal view linear, widening basally and apically, thin paramere encircling shaft at midlength, ejaculatory duct protruding subapically.

Female. Unknown.

Type material. Holotype, male— Panama, Bocas del Toro Province, Quebrada Rambala, near Rambala Jungle Lodge , 3.74 km SSE Rambala, 8.91543°N and 82.15527°W, 120 m, Malaise trap, February 6–12, 2017, E. Carlson. GoogleMaps

Etymology. We take great pleasure in naming this species for our colleague Dr. Bill P. Stark, Department of Biology, Mississippi College, in recognition of his lifetime of work on aquatic insects in the Neotropics.
