Abstract

Seven species of Pseudopecoeloides including five new are described from marine fishes in the waters off the coasts of Queensland, and West and South Australia. The new species are Pseudopecoeloides hickmani n. sp. from Pseudocaranx wrighti (Carangidae), P. lesteri n. sp. from Pseudocaranx dentex and Pseudocaranx wrighti, P. arripi n. sp. from Arripis georgianus (Arripidae), P. atherinomori n. sp. from Atherinonmorus ogilbyi (Atherinidae), P, hafeezullahi n. sp. from Trachurus novaezealandiae (Carangidae). Pseudopecoeloides scomberi Hafeezullah, 1971, which was transferred to Opecoeloides (Odhner, 1928) by Madhavi (1975) is reported from Scomberoides lysan (Carangidae) and returned to Pseudopecoeloides. Pseudopecoeloides tenuis Yamaguti, 1940 is reported from a new host species, Priacanthus macracanthus (Priacanthidae).

Highlights

In erecting Pseudopecoeloides Yamaguti, 1940 for P. tenuis Yamaguti, 1940 from the priacanthid Pseudopriacanthus nipponicus (Cuv. & Valenc.) [sic – ? Pristigenys niphonius Cuvier, Japanese bigeye], Yamaguti (1940) observed that the caecal ends were connected to the excretory vesicle
Fish hosts discussed in this study were collected, mainly by angling or seining, from various sites in Moreton Bay in southeastern Queensland, around Fremantle, Coogee and Woodman Point in Western Australia and off Kangaroo Island, South Australia
Species of Pseudopecoeloides can be divided into two morphological groups based on their sucker ratios, as follows: Group A

Summary

Introduction

Pristigenys niphonius Cuvier, Japanese bigeye], Yamaguti (1940) observed that the caecal ends were connected to the excretory vesicle (i.e. forming a uroproct) He re-examined the specimens of Cymbephallus carangis Yamaguti, 1938 and, finding a uroproct, transferred it to Pseudopecoeloides. P. equesi was described as bearing five distinct papillae on its ventral sucker and, in his original discussion, Manter (1947) thought that it could well represent a new genus. This species was transferred to Dactylomyza by Aken’Ova (2003)
