( Figs. 59–66View FIGURES 59 – 66)

Diplosynapsis  sp. Artigas & Papavero, 1997: 79, figs. 21 – 26; Papavero, Artigas & Lamas, 2009: 29, figs. 80–85.

Diagnosis. Mystax with black setae on superior half and yellow on lower half of facial swelling; 4 – 5 brown and 5 black postocular macrosetae; antepronotum and postpronotum black, grey tomentose; mesonotum reddish brown, sparsely golden tomentose and 2 black stripes; epandrium apex serrated in lateral view ( Figs. 59, 60, 62View FIGURES 59 – 66); gonocoxite apex rounded ( Fig. 63View FIGURES 59 – 66); gonostylus with dorsal elevation medially with small spines, apex wider than the preapical region ( Figs. 63, 64View FIGURES 59 – 66).

Description. Male. Holotype. Head. Scape and pedicel black; 2 black ocellar macrosetae; vertex underdeveloped, black, grey tomentose; frons black, grey tomentose; 4 yellow orbital macrosetae; face black, grey tomentose laterally, facial swelling brown, grey tomentose; mystax with black setae on superior half, yellow on inferior half of facial swelling; palpus with yellow and black setae, being 1 long, thick and apical; proboscis black with yellow ventral setae; labial setae yellowish; occiput grey tomentose; yellow and whitish occipital setae; 4 – 5 brown and 5 black postocular macrosetae.

Thorax. Antepronotum and postpronotum black, grey tomentose; mesonotum reddish brown, sparsely gold tomentose and 2 black stripes; scutellum and mesopleuron reddish-brown, sparsely gold tomentose; portion of katepisternum and meron + metanepisternum black. Chaetotaxy: 1 brown and 1 black notopleural macrosetae; 1 black supra-alar seta; 1 black postalar seta; 3 black dorsocentral setae; 3 long, moderately thick, black anepimeral setae; anatergal setae whitish; one pair of black apical scutellar macrosetae and 1 brown macroseta; black discal scutellar setae; black and yellow katatergal macrosetae; setae on meron+metanepisternals yellowish.

Wing ( Fig. 61View FIGURES 59 – 66). Light Brown, without costal dilation; crossvein r-m beyond middle of discal cell; microtrichia on posterior wing margin arranged in single plane; halter reddish-brown.

Legs. Femora and tibiae reddish-brown ( Fig. 59View FIGURES 59 – 66); tarsomeres brown, except for black apical ones. Chaetotaxy: fore femur basal 2/3 with yellow, ventral setae and apical 1/3 with black setae; mid femur with 4 black setae anteriorly and 4 anteroventrally; hind femur with 3 – 4 black setae anteriorly and 1 yellow and 7 black anteroventrally, 1 black, anterior, preapical dorsal macroseta and 1 yellowish posteriorly; fore tibia with row of thin black setae posterodorsally; mid tibia with 4 black setae anteroventrally; hind tibia with 1 black basal and 1 preapical seta anterodorsally, 1 black preapical seta anteroventrally; tarsomeres with black setae.

Abdomen. Tergites I –V black; tergites 1–3 with grey band on apical margin; tergites and sternites 6–7 with shining silvery tomentum ( Figs. 59, 60View FIGURES 59 – 66); sternites 1–5 black, grey tomentose; sternite 8 brown, apical margin straight, with long yellow setae medially.

Terminalia ( Figs. 60, 62–66View FIGURES 59 – 66). Reddish brown ( Figs. 59, 60View FIGURES 59 – 66); terminalia oblique to body axis ( Fig. 59View FIGURES 59 – 66). Epandrium apex serrated in lateral view (Figs, 59, 60, 62); hypandrium ventral margin with slight median indentation; gonocoxite apex rounded ( Fig. 63View FIGURES 59 – 66); gonostylus with dorsal elevation medially with small spines, apex longer than preapical region ( Figs. 63, 64View FIGURES 59 – 66); ejaculatory apodeme long and wide on proximal region, in lateral view ( Fig. 65View FIGURES 59 – 66); aedeagus apex more or less straight in lateral view ( Fig. 65, 66View FIGURES 59 – 66).

Lengths: Body 18 mm; wing 12 mm.

Holotype condition. Postpedicel lost in both antennae; 1 apical scutellar seta broken off; left wing apex ripped. Wing mounted in microslide with Canada balsam. Part of abdomen and terminalia in microtube with glycerine. Microtube and microslide pinned with specimen.

Variation. Body: 19.1 mm; wing: 12.1 mm; postpedicel black except for brown base; 2 black notopleural macrosetae; 3 black and 1 yellow apical scutellar macrosetae; hind femur with 4–5 black macrosetae anteroventrally.

Female. Unknown.

Etymology. From Latin spina  = spine, referring to the spines present in the gonostylus.

Distribution. Brazil (Rio de Janeiro) ( Fig. 76View FIGURE 76).

Comments. Diplosynapsis spina  sp. nov. seems to be the same species drawn by Artigas & Papavero (1997) and treated as Diplosynapsis  sp. However, the material from those authors was not available for this study. Furthermore, Artigas & Papavero (1997) did not indicate where the specimen that they studied was collected.
