Santos, Claudiney Biral Dos & Curler, Gregory R., 2014, Four new species of Tonnoira Enderlein (Diptera: Psychodidae: Psychodinae) from the Brazilian Atlantic forest, Zootaxa 3760 (3), pp. 463-470 : 467-468

Tonnoira andradei Santos sp. nov.

( Figs. 10–13 )

Diagnosis. Eye bridge divided medially by 0.5 facet diameters. Wing with base of R2+3 not contiguous with R4, CuA unattached basally and apically. Gonostylus bifurcate, with lateral branch slightly longer than medial branch. Epandrial clasping lobes arcuate, tapered from base to apex.

Description. Male. Length total 3.6 mm. Head: eye bridge divided medially by 0.5 facet diameters; interocular suture inverted Y-shaped; antenna with 16 antennomeres; scape cylindrical, 1.9 times the length of pedicel; pedicel spherical; all flagellomeres cylindrical; basal flagellomere 1.1 times the length of second, slightly wider than remaining flagellomeres; apiculus present on flagellomere 14; palpus formula = 1.0: 3.0: 2.6: 2.6 (fig. 10); apical palp segmet not striated. Wing with Sc short, unattached basally and apically, with break near base; base of R2+3 not contiguous with R4; R4 unattached, with break near the base; CuA1 unattached basally; CuA2 unattached basally (fig. 11). Terminalia: Gonocoxites 1.6 times the length of gonostyli, contiguous with hypandrium; gonostyli bifurcated near mid-length; basiphallus appearing trapezoidal in dorsal view; parameres slightly curved, directed posterolaterally, tapering to apex, shorter than distiphallus (fig. 12); hypoproct micropilose, with posterior margin rounded; epandrial clasping lobes arcuate, tapered from base to apex, with two clavate tenacula, one apical and one subapical (fig. 13).

Material examined. BRAZIL, Espírito Santo state, Santa Teresa, Reserva Biológia Augusto Ruschi, (19º54’S, 40º33’W, 820 m. a.s.l.), holotype male, 28.IX.2011, Santos, CB., five paratype males with the same data as the holotype.

Etymology. This species is named for Dr. José Dilermando Andrade Filho, Centro de Pesquisas René Rachou/ Fundação Oswaldo Cruz, Belo Horizonte, Minas Gerais, Brazil, in honor of his contributions to the study of Psychodidae .

Comments. Tonnoira andradei is unique in that it is the only species of Tonnoira described to date with the gonostyli bifurcated at midlength and having branches of nearly equal length. The apiculus on flagellomere 14 of T. andradei is similar to that of T. brisolaii ( Fig. 2 ).
