Description
Neotrichia atopa Thomson and Armitage, sp. n.
Fig. 6.
Diagnosis. Based on the number of ocelli and the spur formula, this species has been placed in the genus Neotrichia. However, the overall appearance of the male genitalia does not seem typical of the genus. The inferior appendage is short and not immediately apparent when viewed laterally, as opposed to the expected long and slender form seen in most other Neotrichia species. Segment IX does not appear to be fused dorsally with tergum X; the dorsal plate is not apparent. The elaborate, sclerotized structure present at the base of the subgenital plate and the inferior appendage in this species also seem unique within the genus.
Male. Forewing length 2.0 mm (n = 1). Head unmodified, with 3 ocelli; antennae unmodified. Tibial spur count 0, 2, 3. Color in alcohol brown, denuded. Genitalia. Abdominal sternum VII without mesoventral process. Segment VIII unmodified. Segment IX anterolateral margin strongly narrowing, withdrawn into segment VIII, posterolateral margin convex; in dorsal view posterior margin concave. Subgenital plate membranous dorsally; in ventral view with pair of apical setae, broadest apically. Bracteole setose, larger than, and extended past, inferior appendage. Inferior appendage small, semi-triangular in lateral view, seemingly fused basally with subgenital plate with elaborate sclerotized structure extending into segment IX. Tergum X membranous, subtriangular in dorsal view. Phallus with wide tubular base narrowing to median constriction, membranous apex with 2 slender processes; 1st process long, with apical emargination; 2nd process shorter and wrapped around 1st process.
Type material. Holotype male— PANAMA: Chiriquí Province: Cuenca 102 (Río Chiriquí Viejo), un. trib., Río Colorado, Mount Totumas Biological Reserve, 8.884717°N, 82.684077°W, UV-light trap,
2.i.2016, B. and T. Armitage (COZEM).
Etymology. The Greek word atopos meaning “out of place, odd, strange, unnatural”, referring to the atypical appearance of this species for this genus.
Genus Ochrotrichia Mosely. The genus Ochrotrichia in Panama previously included 25 species, 18 of which were first described from Panama and 11 of which are currently endemic. Herein we add one new species from Mount Totumas.
