Psychoda divaricata Duckhouse

Psychoda divaricata Duckhouse, 1968: 37 . Type locality: Brazil (Santa Catarina, Nova Teutônia).

Diagnosis. eyes separated by 1.0 facet diameters (males) and 1.5 (females); antenna with 14 flagellomeres, 12th and 13th partially fused, 11th with a spine; male surstylus longer than 1.5 the length of epandrium; paramere inflated and with 2 acute projections apically; distiphallus with 2 arms, one laterally flattened and leaf shaped, the other slender, with acute apex; internal ornamentation of the subgenital plate in U, with 2 small sac-like structures at the base.

Additional characters. Eyes separated by 1.3–1.8 facet diameters (females) and 0.9–1.0 (males); 5–6 supraocular setae; clypeus with 2 stronger lateral alveoli; frontoclypeal suture absent; antenna with spine present on flagellomeres 11 and 13; labellum with 4 apical teeth (3 long and 1 short) and 1–2 lateral setae; wing with Sc vein ending just beyond base of vein Rs; distitarsus with apical projection; female subgenital plate pilose on distal half; aedeagus in 2 parts: dorsal portion less sclerotized, laterally flattened, and leaf-shaped, ventral portion simple, with acute apex; paramere (dorsal part of aedeagus according to Duckhouse (1968) and Bravo et al. (2006)) distally inflated, with 2 acute apical projections; gonocoxal bridge projecting anteriorly, forming a subquadrate plate, and posteriorly, forming 2 lobes; epandrium with 1 pseudo-spiracular opening; surstylus conical, 1.5 X the length of epandrium.

Comments. As stated by Bravo, Cordeiro & Chagas (2006) “the number and the form of the apical flagellomeres observed in P. divaricata – 14 flagellomeres, 12th-13th partially fused, and 14th smallest and spherical – is present in some other Neotropical species”, but we agree that no additional subgenera should be proposed before phylogenetic studies are undertaken. This is the first record of this species in Paraná.
