Cinetus Jurine, 1807  

( Figs. 4B, 4D View FIGURE 4 , 8 View FIGURE 8 , 9 View FIGURE 9 , 12C View FIGURE 12 , 14B View FIGURE 14 , 22C View FIGURE 22 )

Total of specimens found: 6 (females) in four morphospecies.

Diagnosis: Overall size between 2 and 5 mm; mandibles short (mandible length as long as or shorter than the distance between the ventrolateral margins of the head, near the bases of the mandibles) ( Figs. 9A View FIGURE 9 , 12C View FIGURE 12 ); antenna 15-segmented in females, 14-segmented in males. Epomia always well developed; notauli complete, slightly diverging posteriorly ( Fig. 9E View FIGURE 9 ); scutellar fovea subquadrate, relatively large ( Fig. 9E View FIGURE 9 ); posterior extremity of the notaulus directed to a point inside this fovea ( Fig. 9E View FIGURE 9 ); carina between the medial keel and the internal plica present ( Fig. 9C View FIGURE 9 ) or absent. Marginal vein as long as or short- er than radial cell, and as long as or slightly shorter than parastigma ( Figs. 4B, 4D View FIGURE 4 ); third gaster segment almost always very long, dorsoventrally flattened or in the form of a truncated cone, the open end of which is more or less tubular; the gaster apical segments can be otherwise modified, rarely 2-3 clearly defined simple ring segments beyond the large tergite ( Figs. 8 View FIGURE 8 , 9B View FIGURE 9 ); male genitalia with fused volsellae and dentes.

Remarks: Cinetus   species share some character states with Scorpioteleia   . The two genera can be easily dis- tinguished one from each other by the venation; in Scorpioteleia   the marginal vein is always clearly short- er than the radial cell and parastigma ( Figs. 4A, 4C View FIGURE 4 ) ( Macek, 2006). There are fifty nine described species of Cinetus   in the world ( Johnson, 1992; Buhl, 1998; Rajmohana, 2006), being Cinetus tabidus Spinola, 1851   the only species recorded in the Neotropics (Santa Rosa de los Andes, Chile) ( Spinola, 1851) thus far, but there may be up to twenty species in the Region ( Hanson & Gauld, 2006). Nixon (1957) ’s identification key is reliable for the European species, with emphasis on the British fauna.

Distribution: Cosmopolite ( Hanson & Gauld, 2006). In the Atlantic Forest, the six specimens were recorded in Alagoas state and in the southern portion of the biome, from Santa Catarina to Rio de Janeiro ( Fig. 22C View FIGURE 22 ).

Biology: Parasitoids of Mycetophilidae ( Hanson & Gauld, 2006)   .
