Scorpioteleia Ashmead, 1897  

( Figs. 4A, 4C View FIGURE 4 , 10 View FIGURE 10 , 22B View FIGURE 22 )

Total of specimens found: 7 (3 females and 4 males) in four morphospecies.

Diagnosis: Mostly relatively medium sized (3-4 mm); brownish to black species with light coloured appendages; antenna 15-segmented in females, 14-seg- mented in males; head subtriangular in frontal view ( Fig. 10A View FIGURE 10 ); mandibles slightly asymmetrical, left bidentate, right tridentate, crossing at tips; occipital carina incomplete, developed in its upper part; hypostomal bridge and hypostomal carina developed; clypeus slightly convex, lustrous, with truncate lower margin; labrum transverse, slightly emarginated in middle; fore tentorial pits deep; palpal formula 5-3; apical segment of maxillary palps slender, twice as long as penultimate segment; antennal shelf moderately prominent with shallow furrow between toruli. Mesosoma slender, higher than wide, narrower than head; pronotal shoulders angular ( Fig. 10C View FIGURE 10 ); epomia well developed; mesoscutum convex; notauli complete, slightly diverging posteriorly ( Fig. 10C View FIGURE 10 ); parapsidal impressions (situated laterally to the notaulus) usually in form of shallow declivities; scutellum convex, with large subquadrate fovea ( Fig. 10C View FIGURE 10 ); posterior extremity of the notaulus directed to a point inside this fovea ( Fig. 10C View FIGURE 10 ); propodeum subquadrate, convex, with plicae not protruded posteriorly ( Fig. 10C View FIGURE 10 ); medial keel of propodeum simple ( Fig. 10C View FIGURE 10 ); fore tibiae in male slightly widened in middle, with some modified setae ( Fig. 10E View FIGURE 10 ). Radial cell of forewings completely closed, longer than marginal vein ( Figs. 4A, 4C View FIGURE 4 ); parastigma longer than marginal vein ( Figs. 4A, 4C View FIGURE 4 ). Petiole short to long, cylindrical, rugose or ribbed; gaster fusiform ( Figs. 10B, 10D View FIGURE 10 ), the apical segments of female gaster extruded and resembling a scorpion’s tail ( Figs. 10B, 10F View FIGURE 10 ); ovipositor thin and relatively small, with large gonoplacs (= third valvulae); male genitalia with fused volsellae and dentes.

Remarks: Scorpioteleia Ashmead, 1897   was established for S. mirabilis Ashmead, 1897   , by monotypy. Scorpioteleia   shares some character states with Cinetus   such as the slightly posteriorly diverging notauli ( Figs. 9E View FIGURE 9 , 10C View FIGURE 10 ), large subquadrate scutellar fovea ( Figs. 9E View FIGURE 9 , 10C View FIGURE 10 ); oblique stigmal vein in relation to the postmarginal vein ( Figs. 4 View FIGURE 4 A-D) and male genitalia with fused volsellae and dentes. The two genera can be easily distinguished, however, by the alar venation, because in Scorpioteleia   the marginal vein is always clearly shorter than the radial cell and parastigma ( Figs. 4A, 4C View FIGURE 4 ) ( Macek, 2006). In the past, both genera were confused with Miota   , which occurs also in Atlantic Forest. Miota   is clearly different due the presence of parallel notauli ( Fig. 11C View FIGURE 11 ), straight stigmal vein ( Fig. 11D View FIGURE 11 ) and male genitalia with free dentes (not fused to the volsellae). Hellén (1964) suggested the name Eumiota   for the species remaining in Miota sensu Förster. Masner & Muesebeck (1968)   synonymized Eumiota   with Scorpioteleia   . Nevertheless, Johnson (1992) did not follow Masner & Muesebech (1968) and listed, without any comment, four species of Scorpioteleia   (three European and one Nearctic) and three European species of Eumiota ( Macek, 2006)   . Macek (2006) recognized six species of Scorpioteleia   and reviewed the five European species, providing an identification key.

Distribution: Six species are recognized in the Holarctic region (one Nearctic and five European) ( Macek, 2006). Approximately 50 Scorpioteleia   species are estimated to occur in the Neotropical region (L. Masner, pers. comm., May 6, 2015). In the Atlantic Forest the seven specimens were recorded in the southern portion of the biome, from Santa Catarina to Rio de Janeiro ( Fig. 22B View FIGURE 22 ).

Biology: Hosts of most species are unknown, but field and rearing observations suggest that Scorpioteleia   species are associated with fungivorous Mycetophiloidea Nematoceran Diptera   , which develop in soft sporocarps of Basidiomycetes ( Macek, 2006).
