Figs. 2 View FIGURE 2 a, b, c, d

This species appears to be another member of the xena group, perhaps related to Ochrotrichia concha Bueno- Soria & Santiago-Fragoso by the similar trumpet shape of the inferior appendages. However, O. jolandae new species is characterized by the stout, basal, spine on segment X and the long spine-like process on the left side surrounded preapically by a long, hook-like, ventrally directed process.

Male: Length of forewing 2.5 mm. Color in alcohol dark stramineous. Segment IX with posterodorsal margin slightly produced. Segment X in dorsal view a long, narrow, plate with stout, basal spine-like on right side and long, straight spine-like process with apex curved to right, surrounded preapically by long, hook-like process; apical region narrow, slightly curved to right; in left lateral view appears with short, stout basal spinelike and long, straight, spine-like process, surrounded by stout, strongly curved ventrad hook-like process at midlength. Inferior appendages symmetrical, in lateral view trumpet shaped with apex and midventral margin rounded, with band of black peg-like setae, with stout, short, spine-like corner on midventral margin. Phallus arising from conical expanded base, apical region slender with sagittate process.

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, 6–10.iii.1991, Holzenthal, Muñoz, Huisman ( UMSP). Paratype: Same data as holotype, 1 male ( UMSP).
