Ochrotrichia conformalis, new species

Figs. 4 a, b, c

The presence of 2 dark spine-like processes on segment X and similarly shaped inferior appendages in lateral view, make to Ochrotrichia conformalis new species a member of the arranca group (Flint 1972) closely related to O. arranca (Mosely) (Fig. 3), and O. quasi, new species . However, the wide, stout, basal lobe of the inferior appendages in ventral view clearly separates O. conformalis new species from O. arranca (Mosely) and O. quasi, new species .

Male: Length of forewing 2.0 mm. Color in alcohol stramineous. Segment IX depressed, produced anteriad. Segment X in dorsal view with long, slightly curved, dorsal process bearing 2 large black setae; left side with apical hook-like process; in lateral view, ventrally with 2 curved processes, 1 long with acute, ventrally directed apex, the other shorter, wider basally. Inferior appendage in lateral view, with elongate, finger-like dorsal lobe; left inferior appendage with elongate, bifurcate ventral lobe, between lobes 2 short black spineslike; right inferior appendage with large, apically darkened hook-like process, ventral lobe bearing 2 preapical, black spines-like; in ventral view, left and right ventral lobes of inferior appendages appearing short, stout, wide basally, with 2 dark, preapical spines-like; apex acute, ending in long dark spine-like. Phallus long, thread-like.

Female: Unknown

Type material: Holotype, male. COSTA RICA: Alajuela: Reserva Forestal San Ramón, Río San Lorencito and tribs., 10.216º N, 84.607º W, el. 980 m, 1–4.v.1990, Holzenthal & Blahnik (UMSP). Paratypes: same data as holotype, 2 males (UMSP, NMNH).

Etymology: From the Latin word conformalis; in reference to the similarity of this species with O. arranca (Mosely) .
