Rhinoleucophenga lopesi Malogolowkin, 1946

( Figures 2 a–d; 3a–d; 4a–b; 5; 6a–d; Table 1)

Rhinoleucophenga lopesi Malogolowkin, 1946: 424 . Malogolowkin, 1946: 417 (key), 424 (figures 14-15); Rhinoleucophenga sp.1 (Blauth and Gottschalk, 2007); Mata et al., 2008: 57, 58 (table); Rhinoleucophenga capixabensis Culik and Ventura, 2009: 418 (NEW SYNONYMY).

Material examined: HOLOTYPE ♀ labelled (dried mounted material, deposited in CEIOC) labelled “ Rhinoleucophenga lopesi DET—Chana Malogolowkin Rio V-946 \ Brasil , Rio de Janeiro, 8-934, H. Souza Lopes \ Inst. Oew. Cruz n° 8.125 \ HOLOTYPUS ”. The right wing, III–VII tergites and the terminalia were disarticulated and lost . Holotype of R. capixabensis (in ethanol 70%, deposited in MNRJ) labelled “ Brasil , Espirito Santo, Cachoeiro de Itapemirim, INCAPER FE Pacotuba 16.I.2008, col. M.P. Culik ex. A. comosus + D. brevipes Rhinoleucophenga capixabensis HOLOTYPE ” and 0 5 paratypes of R. capixabensis (in ethanol 70%, 0 3 deposited in MNRJ and 0 2 deposited in UFES) labelled “ Brasil , Espirito Santo, Cachoeiro de Itapemirim, INCAPER FE Pacotuba 16.I.2008, col. M.P. Culik ex. A. comosus + D. brevipes Rhinoleucophenga capixabensis PARATYPE ”.

Diagnosis. General body color brown; front covered with ca. 40 scattered interfrontal setulae. Gena brownish with an irregular brown spot. Three pairs of prescutellar acrostichal setae. Hyaline wings. Abdominal tergite II and III with brown stripes interrupted medially.

Description. Based on the holotype:

Head ( Fig. 2 a, c). Front homogeneously brownish, covered with ca. 40 scattered interfrontal setulae; ocellar triangle brownish with dark brown ocelli. Carina nose-like and ca. 90% sulcated. Face brownish; gena brownish with an irregular brown spot; antenna with pedicel yellow. Palpus yellowish with ca. 20 (15-20) setae on lower part. Arista lost.

Thorax ( Fig. 2 b, c). Scutum brownish and scutellum brown. Ten irregular rows of acrostichal setulae. Three pairs of prescutellar acrostichal setae. Pleura brown and halteres yellowish. Legs brownish.

Wings ( Fig. 2 d). Hyaline, without spots.

Abdomen. Abdomen brownish; tergite II with brown stripes interrupted medially.

For more measures and indices see Table 1.

Note. We analyzed the holotype and five paratypes of R. capixabensis (the holotypus and two paratypes ( Fig. 3 a–d and 4) with measurements presented in Table 1) and ten specimens collected in the municipality of Tangará da Serra, State of Mato Grosso, Brasil (14°39'05"S; 57°25'25"W) (measurements presented in Table 1). Both the type specimens of R. capixabensis and the specimens collected in State of Mato Grosso present similar morphological characters with the holotypus of R. lopesi . Aristae of these specimens with 5–6 dorsal and 3–4 ventral branches. The male terminalia of a paratype of R. capixabensis ( Fig. 5 a–b) and of the five specimens collected in State of Mato Grosso ( Fig. 6 a–d) were similar, with the typical of ringed-shape aedeagus in Rhinoleucophenga . The epandrium is microtricose, with c.a. 60 upper+lower setae. Large cerci, free and ventrally folded. Surstyli fused with epandrium with 16–18 prensisetae. Aedeagus dorsoventrally flattened, with narrowed apex. Two long paraphysis articulated anteriorly to the aedeagal apodeme, with three setulae in apical region. Hypandrium slightly concave, rounding aedeagus, with a posterior cleft and two lateral projections.

Distribution. Brazil (States of Rio de Janeiro, Mato Grosso, Espírito Santo). Mata et al. (2008) recorded this species in Paranã Valley, Central region of Brazil, but the exact locality was not mentioned.
