Remarks. With the morphological observation of several specimens, some characters have been redefined, new characters added and new measures and ratios resized by modifying the genus diagnosis. The characters related to aedeagal complex are the best for specific identification, but not easily visible due to overlapping structures ( Roback, 1971). Paggi et. al. (2009) revised the nomenclature of some important diagnostic structures, such as: the first palpomere, the megaseta, gonostylus apex, aedeagal blade, dorsal lobe, lateral lobe and basidorsal lobe.

We analyzed not previously observed structures, such as the presence of anal point and gonostylus with keel. In the male adults, the pigmentation of the legs appears to be constant in species, but caution is needed, because, depending on position, the side may not view the bands, making it ideal to observe several individuals for the analysis of possible complete or incomplete bands. In the pupa, the main characters that helped in species identification were: thoracic horn morphology, abdominal and wing sheath pigmentation, anal lobe and genital sac morphology. In the larva, the presence of dorsal setae S 12 and S 13 were observed for the first time. The main characters that helped in larvae species identification were pigmentation and morphology of the head capsule, the morphology of the postoccipital margin, ligula morphology, pigmentation and length of procercus, pigmentation of the posterior parapod claws and the presence of claw with wide base and truncated apex.

Roback (1971) split Ablabesmyia in two subgenera, Ablabesmyia s. str. and the subgenus Karelia . Ablabesmyia s. str. has a worldwide distribution, while A. ( Karelia ) is found in all regions except Australia and Antarctica. Roback (1983) described A. metica from Colombia and placed it in a new subgenus Sartaia . Later Roback (1985) erected the subgenus Asayia for A. annulata ( Say, 1823) . Ablabesmyia (Sartaia) is only known from the Neotropical region, while A. ( Asayia ) occurs in both the Nearctic and Neotropical regions ( Murray & Fittkau 1989). Although Ablabesmyia species are common in the Neotropical region, little is known about their immature stages. Ablabesmyia (Sartaia) metica Roback, 1983 was described only with adults stages and Neubern et al. (2008) described their immature stages. However, we chose not to state species to each subgenera, because there are inconsistencies in the establishment of these groups without the actual knowledge of the fauna and a phylogenetic analysis. That is easily seen, for example, in Ablabesmyia fusariae sp. n.. Species belonging to the annulata group have the ligula teeth straight and all the claws of posterior parapods yellow, but Ablabesmyia fusariae sp. n. has ligula teeth in concave arch and all yellow claws. Ablabesmyia fusariae sp. n. is notoriously different from the other species of the genus, mainly due to the morphology of the anal lobe, but we can only define the subgenera with a phylogenetic analysis.
