Contribution to the knowledge of Atrichobrunettia Satchel, 1953 (Diptera, Psychodidae) from Brazil

A new species of moth-fly, Atrichobrunettia (Polibrunettia) longipalpis sp.  nov. (Psychodinae, Psychodidae), from the Brazilian Atlantic Rain Forest is described. It can be distinguished from other species of the subgenus mainly by the length of palpus that is longer and by the dentate distal margin of hypandrium. Here the distribution of A. angelae Bravo, 2006 and A. paranaensis Bravo, 2005 is reviewed and morphological data to A. paranaensis Bravo, 2006 is given to complement the original description of the species.

The present work aims to increase the current knowledge of Atrichobrunettia with the description of a new species, new morphological data to A. paranaensis Bravo, 2006; and new records to A. angelae Bravo, 2006 and A. paranaensis.

MATERIAL AND METHODS
The studied specimens will be deposited in the Entomological Collection Prof. Johann Becker of the Museu de Zoologia da Universidade Estadual de Feira de Santana, Bahia, Brazil (MZFS). The specimens were treated with 10% potassium hydroxide (KOH) for approximately three hours, neutralized in acetic acid 20% for 10 minutes, dehydrated in ethanol, diaphanized in clove oil and mounted in Canada balsam on slides. The general morphology follows Cumming & Wood (2017). All drawings were made with the aid of a camera lucida and digitally processed using Inkscape 0.48 software. Measurements are given in millimeter (mm). of alveoli divided medially; clypeus scar patch of alveoli subquadrangular, undivided. Antenna with scape cylindrical, 1.4 times the length of pedicel; pedicel spherical; flagellum with 14 nodiform flagellomeres, decreasing in size from base to apex, 2-10 strongly eccentric flagel-lomeres; 14 th flagellomere with small apiculus (Fig. 1B); a pair of S-shaped ascoids in the flagellomeres 1-13 (Fig. 1C); Palpus formula 1.0: 5.2: 4.4: 5.2. Mouthparts extending beyond basal segment of palpus; labellum with apicolateral bristles (Fig. 1A). Wing with pointed apex; Sc short and not sclerotized; Rs pectinate, radial fork apical to medial fork; R₅ ending at the wing tip; CuA₂ ending apical to the level of medial fork (Fig. 1D).

TAXONOMY
Male Terminalia: Cercus cylindrical longer than the length of epandrium; internal surface of cercus with two short bristles; apex with at least 20 long tenacula with rounded tips (Figs. 1E, F, H). Epandrium bare, subrectangular, wider than long, proximal margin concave in ventral view and with two foramina near proximal margin (Fig. 1F). Gonocoxite bare, cylindrical, the same length as gonostylus; gonocoxal apodemes fused, forming a bridge and in contact with proximal portion of ejaculatory apodeme; ejaculatory apodeme narrow and short.
Gonostylus tapered and curved with three bristles at apex, distal one longer than other two. Hypandrium wide, with irregular, dentate and little sclerotized area in the distal margin. Aedeagus with bilobed apex; parameres subtriangular, pointed at apex, sclerotized and divergent, with the same length as gonostylus (Figs. 1G, H). Comments: Based on the key to males of Neotropical species of Atrichobrunettia of Bravo (2006), the new species is included in the subgenus Polibrunettia by following characters: eye bridge separated, narrow; scape 1.0x-2.0x the length of the pedicel; R₅ ending at the apex of the wing; apodemes fused forming a gonocoxal bridge; post-hypandrial wide and plate without alveoli; and subtriangular parameres. In addition, the new species is morphologically similar to A. longipenis Bravo, 2006 by the length of palpus, little longer in the new species, but differs because the ejaculatory apodeme is wider in A. longipenis; the distal margin of hypandrium dentate in the new species and straight in A. longipenis and by the direction of the parameres, more divergent in A. longipenis. The current distribution of the new species included the southeast and northeast of Brazil in the Atlantic Rain Forest of states of São Paulo and Bahia.
Male description: Head ( Fig. 2A (2006) is complemented with observations made in specimens collected in the State of São Paulo (Sete Barras), which is a new record of the species expanding the northern distribution of the species.

Atrichobrunettia angelae Bravo
Atrichobrunettia angelae Bravo, 2006: 17-19, figs. 20-23. Comments: Males of A. angelae are recognized by the male terminalia, with the parameres longer than gonocoxite, sclerotinized, triangular and with curved apex. The type specimens were examined and allow the identification of the specimens.
