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 : 465-467

Tonnoira ferreirai Santos sp. nov.

( Figs. 6–9 )

Diagnosis. Eye bridge divided medially by 0.3 facet diameter. Wing with base of R2+3 not connected to R4, CuA not attached basally or apically. Gonostylus bifurcated near the base with lateral branch about ¼ the length of mesal branch. Epandrial clasping lobes tapered from base to apex, strongly curved apically, with two tenacula.

Description. Male. Length total 3.3 mm. Head: eye bridge divided medially by 0.3 facet diameters; interocular suture inverted Y-shaped; antenna with 16 antennomeres; scape cylindrical, 1.7 times the length of pedicel; pedicel spherical; flagellum with 14 flagellomeres; flagellomeres cylindrical; basal flagellomere 1.1 times the length of second; apiculus present on flagellomere 14; palpus formula = 1.0: 2.3: 2.6: 2.6 (fig. 6); apical palp segment not striated. Wing with Sc short, with apex unattached; base of R2+3 not connected to R4; R5 unattached basally, terminating slightly posterior to wing apex; CuA1 unattached basally; CuA2 free (fig. 7). Terminalia: Gonocoxites 1.6 times the length of gonostyli, contiguous with hypandrium; hypandrium narrow, arcuate in dorsal view; gonostylus bifurcated near base with lateral branch about ¼ the length of medial branch; basiphallus ovoid; parameres slightly curved, directed posterolaterally, tapering to apex, shorter than distiphallus (fig. 8); epandrium shorter than wide, appearing U-shaped with the pseudospiracular opening; hypoproct micropilose, with posterior margin rounded; epandrial clasping lobes tapered from base to apex, strongly curved near apices, each with one apical and one subapical tenaculum (fig. 9).

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

Etymology. This species is named for Dr. Adelson Luiz Ferreira, Universidade Federal do Espírito Santo, in honor of his contributions to the study of Psychodidae in Espírito Santo, Brazil.

Comments. Tonnoira ferreirai can be readily distinguished from other species by the narrowly divided eye bridge with four facet rows and the bifurcate gonostyli with markedly shorter lateral branches. T. andradei also has bifurcate gonostyli, but with lateral branches longer than medial branches. Overall, T. ferreirai appears to be most similar morphologically to T. andradei . The apiculus on flagellomere 14 of T. ferreirana is similar to that of T. brisolaii ( Fig. 2 ).
