Description of immature stages and adult diagnosis of Stilobezzia coquilletti Kieffer 1917 (Diptera: Ceratopogonidae)

Abstract

The pupa and larva of Stilobezzia (Stilobezzia) coquilletti Kieffer are described, and a diagnosis of the adult is given. All described stages were photomicrographed and illustrated by using phase-contrast microscope, plus Scanning Electron Microscope in the case of the larva. Immature stages were collected in a shallow stream of sandy bottom nearby Manaus, Brazil. The pupa is compared with S. (S.) fiebrigi Kieffer, and the larva with S. (S.) antennalis Coquillett.

First description of immature stages and adult females ofStilobezzia(Acanthohelea)megatheca(Diptera: Ceratopogonidae) from Patagonia

“…Pupae observed on trays showed a semi-circular, slow abdominal movement typical of other ceratopogonid pupae. mandibularis, epipharynx less massive and a cylindrical maxillary palpus (Hribar, 1993;Ronderos et al, 2008bRonderos et al, , 2012Cazorla et al, 2013). This species shares with S. (S.) coquilletti and S. (S.) fiebrigi the presence of medium-sized setae on the caudal segment, a character state typical of larvae breeding in shallow water and muddy bottoms (Cazorla et al, 2013).…”

New contributions to the knowledge of the immatures of Stilobezzia punctulata Lane and Stilobezzia fiebrigi Kieffer (Diptera: Ceratopogonidae)

“…There are at present 70 extant species of Stilobezzia inhabiting the Neotropical region (Borkent, 2012;Cazorla, 2013). However and despite the great importance of knowing the ontogeny, immatures of this genus have been poorly studied, the larvae of only 4 species and the pupae of 13 species have been described in this region (Borkent & Spinelli, 2007;Ronderos et al, 2008a;Cazorla et al 2012;Ronderos et al, 2012).…”
