Material examined. 1 ♂, BRASIL, MS [Mato Grosso do Sul]: Corguinho, Taboco , Reserva Quinta do Sol. 19°46’45.4”S, 55°14’36.2”W. 12–29.viii.2012. Malaise 13. Lamas, Nihei & eq. cols. [ MZUSP] ( Fig. 2) .

Redescription. Male. Body length 3.2 mm; wing length 2.6 mm ( Fig. 12).

Female. Unknown.

Color. Frons mat black; fronto-orbital plate shining black; upper dark orbit touching ovt and ivt; ocellar triangle mat black; lunule silvery; face brown with grey pollinose; clypeus black, sligltly shiny; gena dark brown; antenna and arista entirely brown; palpus brown; proboscis light brown; labellum light brown, with brown setae; scutum dark brown, weakly shining; scutellum dark brown; postpronotum, notopleuron, anepimeron, anepisternum, katepimeron, katepisternum, and meron dark brown; haltere entirely light yellow; calypters light yellow with margin and fringe brown; upper fourth of wing brown and with brown area from radial sector reaching transversal r-m and dm-cu veins; legs dark brown; pulvilli yellow; abdomen entirely dark brown.

Head. Frons strongly visible above eye margin in lateral profile; 2 ors, first broken, second reclinate; 2 sligtly reclinate ori, ori shorter and thinner than ors; orbital setulae slightly reclinate in one row; facial keel undifferenciated; eye height/ parafacialia+gena: 3; ocellar triangle short, ending before second ors; lunule high, about 30% of frons length; clypeus obtuse; epistoma height 0.04 mm; first flagellomere rounded and finely pubescent; arista long, about 2/3 of vertical height of eye, finely pubescent; vibrissa strong, measuring half of aristal length.

Thorax. Acr in eight irregular rows; prsc present; 1+3 dc, increasing in size from presutural to third postsutural; 2 npl, similar in size. Wings. Wing tip between R 4+5 and M; R 4+5 and M slightly recurved; C sections 2–4: 0.68:0.15:0.15; ultimate section of CuA 1 0.44 length of basal section; r-m distal to midpoint of dm, close to limit of apical third. Legs. Fore tibia without pd; mid tibia with 2 pd on middle third.

Terminalia. Epandrium large and rounded with long setae; cercus short, slightly less than 1/3 height of epandrium and with long setae and one distinct at apex; surstylus oblong and large with about 23–32 setae; hypandrium U-shaped; phallapodeme about twice length of hypandrium; mesophallus tubular; distiphallus as in Figs 55 and 56; ejaculatory apodeme broad, at its broader part about 3.3 times wider than constricted area at base ( Fig. 57).

Distribution. Panama, Mato Grosso do Sul ( Brazil). New record from Brazil.

Remarks. Phytobia kallima was described by Frost (1936) based only on external characters. Here we provide the first description of the male terminalia. It was previously known from Panama and differs from the other species by the conspicuously pictured wing and by the shape of the phallus, besides the broad ejaculatory apodeme.
