Diagnosis.

Based on the elongate inferior appendages, this species is placed in the Ochrotrichia tenango group of Flint (1972), with some similarity to O. assita Bueno-Soria and Holzenthal and O. longispina Bueno-Soria & Holzenthal, both of which occur in Panama. The new species is separated by the length of the inferior appendage which is approximately 6 times as long as wide, while in O. longispina, the ratio of length to width is 9 ×. In O. assista, the ratio of length to width in the inferior appendages is approximately 3 × and the shape is rectangular, while in the new species and O. longispina, the width is narrow. There is also some similarity to O. froehlichi Desiderio, Moreno and Hamada from Brazil, but in this species, the length of the inferior appendage is not as long as that of the new species and the apex of tergum X is shallowly rather than deeply divided.

Description.

Male. Total length 2.5–3.5 mm (n = 25), 38 antennal segments, wings and body brown in alcohol. G enitalia (Fig. 10). Abdominal segment VII and VIII annular, the former lacking a posteroventral process. Segment IX in lateral view posteriorly sinuate, tapering anterodorsally; narrowing anteriorly and deeply divided mesally; in ventral view, truncate; in dorsal view, with wide mesal incision. Tergum X divided at mid-length, right process wide basally, narrowing distally to acute apex, left process sinuate, widest at mid-length and acute apically; in lateral view, upper process, wide at mid-length, narrowing apically to downturned hook, lower process thin over length, gently curving upwards. Inferior appendage in lateral view thin and elongate, about 6 times as long as wide, widest sub-basally, tapering distally, apex rounded, numerous peg-like setae on inner posterior and ventral margin; in dorsal and ventral views, wide basally, gradually tapering distally to rounded apex, peg-like setae continuous on mesal margins. Phallus in dorsal view thin and elongate, widening apically to rounded knob, with sharp points subapically.

Female and immature stages.

Unknown.

Etymology.

Named for the stream, Quebrada Martínez, in which the types were collected. Located in the Bosque Protector Palo Seco Protected Area, administered by the Ministerio de Ambiente, on the Panama’s Caribbean slope, this is a first order stream in the Río Guabo watershed of the Ngäbe Buglé Comarca (Kankintú District). The word Martínez is a masculine name peculiar to Hispanic-American communities and means “ son of Martin ”. “ Martin ” is the Spanish form of the name “ Martinus ”, associated with the name Mars, which from the Latin implies “ male ”. The name is a noun in the genitive case.
