Miota Förster, 1856

( Figs. 11 , 24C )

Total of specimens found: 2 (males) in one morphospecies.

Diagnosis: Medium sized (3-4 mm); mandibles short (mandible length shorter than the distance between the ventrolateral margins of the head, near the bases of the mandibles) ( Fig. 11A ); antenna 15-segmented and filiform in females, 14-segmented in males. Epomia present or absent; notauli parallel ( Fig. 11C ); scutellar fovea relatively large, subquadrate ( Fig. 11C ), posterior extremity of the notaulus directed to a point inside this fovea ( Fig. 11C ). Stigmal vein straight, perpendicular to the postmarginal vein; marginal vein longer than or as long as parastigma ( Fig. 11D ); well developed postmarginal vein ( Fig. 11D ). Basal sculpture of macrotergite with long medial furrow and short lateral striation; the apical segments of the female’s gaster can be extruded and then resemble a scorpion’s tail; male genitalia with free dentes, not fused to volsellae.

Material examined: BRAZIL: Espírito Santo: Domingos Martins, Parque Estadual da Pedra Azul , 20°25’55”S, 41°00’53”W, 26.viii-02.ix.2003, C. Azevedo e eq. col., 2 ♂♂. L. Masner det.

Remarks: There are 56 described species of Miota in the world ( Johnson, 1992; Buhl, 1998), being M. brevinervis, Kieffer, 1906 the only species recorded in the Neotropical region (São Marcos, Nicaragua) thus far ( Kieffer, 1906). Scorpioteleia and Cinetus have been confused with Miota , which is clearly different due the presence of parallel notauli ( Fig. 11C ), straight stigmal vein ( Fig. 11D ) and male genitalia with free dentes, not fused to the volsellae ( Macek, 2006).

Distribution: Holarctic, Oriental and Neotropical ( Johnson, 1992). The specimens listed above were collected by Celso Azevedo in Espírito Santo state ( Fig. 24C ) and not by our survey; they are deposited at the Federal University of Espírito Santo collection. Dr. Masner kindly called our attention to the specimens, which complement the list of recorded Belytinae occurring in the Atlantic Forest.
