| abstract | Pediculaster perottii spec. n. is described. It was collected from Haematobia irritans L. (Diptera: Muscidae, Stomoxynae) in a field at Miramar in the south-eastern part of the Buenos Aires Province in Argentina, South America. The shape of the pharyngeal pumps was used as a taxonomic criterion in addition to the traditional morphological structures. P. perottii resembled Pediculaster copridis Camerik and Coetzee 1998, collected from cattle dung in South Africa. The second author (SHC) collaborated by taking micrographs through the interference contrast optical tecniques. However, using these optics, the pharyngeal complex was not always clearly visible or obscured by exoskeletal structures. In addition, the shape of the individual pumps often depended on the angle at which these pumps were viewed. With the Confocal Laser Scanning Microscope (CLSM)facility on the same Zeiss 410 CLSM, using the correct laser beams, the pumps autofluoresced, which made it possible to optically section them. The sequence stack which was obtained was rendered into a 3D volume, which was rotated through its Y-axis to visualise the pumps real shape. This rotation around the X-axis disclosed that the pump was not a flat, 2-D structure but that it was thicker around the oesophagus and tapered off in the lateral direction, gaving it a biconvex shape. |
