New species of Ablabesmyia Johannsen (Diptera, Chironomidae, Tanypodinae) from the Neotropical Region, with description of male adults and immature stages

Abstract

A new species of genus Ablabesmyia is described. The larvae were collected associated with aquatic macrophytes in ponds from the Southeast of Brazil. In laboratory, the larvae were reared to obtain pupae and adults.

A new species of the genus Ablabesmyia Johannsen from the Neotropics and description of the pupa of Ablabesmyia bianulata Paggi (Diptera: Chironomidae: Tanypodinae)

“…is also similar to the Neotropical A. oliveirai Oliveira et Gessner, differing in the coloration pattern of thorax and abdomen. Moreover, in the later species the tibia of fore leg is four banded, the DL (VoM in Oliveira & Fonseca-Gessner 2006) demonstrates numerous long and thin terminal filaments, the tip of BL is rounded (VoS in Oliveira & Fonseca-Gessner 2006), the BL does not reach the BDL, the LR 1 is lower and the LR 2 , LR 3 are higher (0.73, 0.88 and 0.90 in A. oliveirai for p 1 , p 2 and p 3 respectively), the tibial spurs are shorter (52-67 in p 1 ; 59-63 and 37-58 in p 2 ; 50-67 and 65-89 in p 3 of A. oliveirai) and the AR is higher (2.1-2.38 in A. oliveirai, C. Oliveira pers. comm).…”

“…The cosmopolitan Ablabesmyia is conformed by four subgenera: Ablabesmyia Johannsen, Asayia Roback, Karelia Roback and Sartaia Roback (Roback 1971(Roback , 1985Murray & Fittkau 1989). At present there are 11 species of Ablabesmyia known from the Neotropics -eight listed by Spies & Reiss (1996), the remaining three described by Paggi & Añón Suárez (2000), Grund (2005) and Oliveira & Fonseca-Gessner (2006). Four of these were recorded from Argentina: Ablabesmyia infumata (Edwards), A. punctulata (Edwards), A. bianulata Paggi and A. reissi Paggi. The first two were originally described by Edwards (1931) as Pentaneura.…”

Primer registro de Ablabesmyia (karelia) cinctipes (Diptera, Chironomidae) para Cuba

“…El género Ablabesmyia Johannsen, 1905 (Diptera, Chironomidae) ha sido mencionado para Cuba en inventarios faunísticos de algunos embalses distribuidos por todo el país, incluyendo la Isla de la Juventud (Poddybnaya et al, 1976;Biochino, 1976;Plasencia, 1987;Plasencia y Calzadilla, 1987) aunque no aparece referido en los compendios de Alayo y García (1983) y Alayo y Garcés (1989). Los estudios en los que se menciona no refieren especie alguna, probablemente debido a que la identificación de los ejemplares de Ablabesmyia es muy difícil sin tener en cuenta las fases de larva y pupa relacionadas (Oliveira y Fonseca-Gessner, 2006). Ablabesmyia (Karelia) cinctipes (Johannsen, 1946), descrita a partir de ejemplares de La Florida (EUA) se distribuye además, en otras localidades de EUA (Hudson et al, 1990), América Central, algunas de las Antillas Menores (Spies y Reiss, 1996) y Bahamas (Roback, 1970).…”
