( Figures 9 a–d; 10a–d; 11a–d; Table 1)

Rhinoleucophenga personata Malogolowkin, 1946: 422 . Malogolowkin, 1946: 417 (key), 423 (figures 11–13); Mata et al., 2008: 57, 58 (table).

Material examined: HOLOTYPE (dried mounted material, deposited in CEIOC) labelled “ Rhinoleucophenga personata DET—Ch. Malogolowkin Rio, 5-946 \ Salobra jan. 941 Mato Grosso Com. I.O.C. \ Inst. Osw. Cruz N ° 8122 \ Holotypus ” . PARATYPE (dried mounted material, deposited in CEIOC) labelled “ Rhinoleucophenga personata DET. Chana Malogolowkin Rio, V. 946 \ Salobra jan. 941 Mato Grosso Com. I.O.C.\ Inst. Osw. Cruz N ° 8123 \ PARÁTIPO”. Both specimens were with their terminalia disarticulated and lost.

Diagnosis. General body color brown. Front covered with ca. 28 scattered interfrontal setulae. Gena brownish with an irregular brown spot. Scutum covered with a longitudinal dark brown stripe. Two pairs of prescutellar acrostichal setae. Femur proximally brown and distally brownish. Hyaline wings. Abdominal tergites with large brown stripes widely interrupted medially. Body length ca. 3.87 mm (3.60–4.15).

Description. Holotype and paratype present the same follow characteristics:

Head ( Fig. 9 a, c). Front ventrally brownish and superiorly brown, covered with ca. 28 scattered interfrontal setulae; ocellar triangle and ocelli brown. Carina nose-like and ca. 75% sulcated. Face brownish; gena brownish with an irregular brown spot; antenna with flagellomere proximally brownish and distally brown, pedicel dark brown; arista with 7 long dorsal branches and 5 long ventral branches plus terminal fork. Palpus yellowish with ca. 30 (25–30) setae on lower part.

Thorax ( Fig. 9 b–c). Scutum brown and scutellum dark brown, scutum covered with a longitudinal dark brown stripe. Ten irregular rows of acrostichal setulae. Two pairs of prescutellar acrostichal setae. Pleura dark brown and halteres yellowish. Legs brownish (femur proximally brown and distally brownish).

Wings ( Fig. 9 c). Hyaline, without spots.

Abdomen ( Fig. 9 d). Tergites II–V with large brown stripes widely interrupted medially.

Male terminalia. In the manuscript of Malogolowkin (1946) it is possible to notice an aedeagus ring-like shaped, epandrium with an elongated ventral lobe and ca. 13 prensisetae.

For more measures and indices see Table 1.

Distribution. Known from the type locality (probably Salobra, a district of municipality of Miranda in the State of Mato Grosso do Sul, Brazil) and from the Ecological Reserve of Raso da Catarina, Municipality of Paulo Afonso, Bahia, Brazil (9°30'39"S 38°32'12"W). Mata et al. (2008) recorded this species in the Paranã Valley, Central region of Brazil but the exact locality was not mentioned.

Note. A specimen from Ecological Reserve of Raso da Catarina, Municipality of Paulo Afonso, Bahia, Brazil (9°30'39"S 38°32'12"W) collected by G.F. Oliveira, was reviewed and had the morphology described ( Fig. 10 a–d). The specimen (conserved in ethanol 70%) presents the same external morphological characters of R. personata , except by the number of scattered interfrontal setulae ca. 50 and the palpus with ca. 40 setae on lower part. The male terminalia ( Fig. 11 a–d) is characterized by aedeagus ring like, wider medially, with a dorsal sclerotized structure shaped like a “duck’s bill”. Epandrium microtrichose with ca. seven upper and 15 longer lower setae on each side. Ventral lobe elongated. Surstyli with 12 prensisetae. Cerci elongated, with ca. 30 setae each one, eight longer setae in the apical portion. Complementary measures and indices see Table 1.
