Aphestia Schiner, 1866 is characterized by the escape about two times the length of the
pedicel, post pedicel about 2.5 times the length of escape and pedicel together with truncate
apex and also by the presence of lateral marginal macrosetae in all abdominal tergites or
restricted to the first two tergites. The genus had three valid species: Aphestia annulipes
(Macquart, 1838), Aphestia chalybaea von Röder, 1881 and Aphestia nigra Bigot, 1878. Five
synonyms have been already proposed for the Aphestia species and the original descriptions
were very succinct, ambiguous and offered few useful characters for the species
identification. A taxonomic study of Aphestia was realized with the analisis of external
morphological characters as well as male and female terminalia. We analyzed 367 specimens
obtained through loan from many national and abroad collections. We found 11 valid species
and from these, eight are new: Aphestia amazonica sp. nov.; Aphestia clausicella sp. nov.;
Aphestia dicowi sp. nov.; Aphestia fisheri sp. nov.; Aphestia fritzi sp. nov.; Aphestia
nigrifemur sp. nov.; Aphestia nigriseta sp. nov. and Aphestia spatulata sp. nov. Two species
were redescribed: Aphestia annulipes and Aphestia nigra. Two species that were treated as
junior synonym of Aphestia annulipes, had their status revalidated and were redescribed,
being: Aphestia brasiliensis Schiner, 1866 sp. reval., e Atomosia affinis Macquart, 1850 sp.
reval. Aphestia calceata Schiner, 1867, that was considerated a junior synonym of Aphestia
annulipes, is now considered a junior synonym of Aphestia brasiliensis as: Aphestia calceata
Schiner, 1867 sin. nov. Atomosia andrenoides Bromley, 1934, that was a junior synonym of
Aphestia nigra, was redescribed, had its status revalidated and a new combination with
Aphractia Artigas, Papavero & Serra, 1991, was proposed: Aphractia andrenoides (Bromley,
1934) sp. reval.; comb. nov. Aphestia chalybaea von Röder, 1881, was transferred to
Cyanonedys Hermann, 1912, becoming Cyanonedys chalybaea (von Röder, 1881) comb.
nov. Two new synonyms were proposed for Cyanonedys chalybaea: Cyanonedys leucura
Hermann, 1912 sin. nov., type species of the genus, and Clariola nigriscens Ricardo, 1912
sin. nov., that already was a junior synonym of Cyanonedys leucura. The geographic records
of the species were increased and a dichotomous illustrated key for the Aphestia species was
presented. |
