description
(Figs 1 – 11) Type-species: Mitinha neri, sp. nov. by present designation. Gender masculine.
diagnosis
Diagnosis. This genus has typical Mythicomyiinae wing venation: vein R 2 + 3 ending in R 1 before junction with costa forming a small triangular cell r 1, and vein R 4 + 5 ending in costa at a level clearly beyond end of vein M 2 (Fig. 3). It can be separated from other genera in the subfamily by the following combination of characters: antennal stylus placed apically on second flagellomere (Fig. 2); costal vein circumambient; vein R 4 + 5 gently sinuous; r-m crossvein placed slightly beyond basal third of cell dm; cell dm short; crossvein dm-cu slightly longer than m-m crossvein; vein M 1 rather straight, more than two times cell dm length; vein A 1 short, stopping at alular incision level; anal lobe not keel-shaped (Fig. 3); three spermathecae; sperm pump jar-shaped with translucent dilation (Fig. 9); each spermathecal duct extremely elongated, twisted, spiraled distally (Fig. 10).
discussion
Discussion. Within Mythicomyiinae, Mitinha shares the apical stylus with Mythenteles Hall & Evenhuis but can be easily separated from it by the circumambient costal vein (costa incomplete, stopping between R 4 + 5 and M 1 in Mythenteles (Fig. 22 )); it shares the circumambient costa and small dm cell with Reissa Evenhuis & Baéz but can be separated from that by the apical stylus (subapical in Reissa), r-m crossvein placed slightly beyond the basal third, and cell dm rather parallel sided and same length as last section of vein CuA 1 (r-m placed slightly before middle and cell dm rather angulated and shorter than last section of vein CuA 1 in Reissa (Fig. 23 )).
distribution
Distribution. State of Piauí, Brazil, Parque Nacional Serra das Confusões, one of the more arid places in Northeast Brazil, with typical Caatinga vegetation.
etymology
Etymology. The generic epithet Mitinha is a noun in apposition and refers to the nickname of José Wilmington Paes Landim Ribeiro, administrator of the Parque Nacional Serra das Confusões, who helped us with field logistics, transportation and laboratory facilities.
