Abstract

Two new dilepidid cestodes parasitic in common landbirds of Ivory Coast are described. Spiniglans thomassankara sp. nov. was found in Ploceus nigerrimus castaneofuscus (Ploceidae) and other Ploceus species along the lagoon system of the South East of the country. It shows characters similar to those of members of both Spiniglans and Dictymetra but lacks a clearly visible ductus masculinus. It is characterized by 24-26 comparatively long hooks and a massive ovary. Monopylidium comoensis sp. nov. was found in Gymnoris dentata (Passeridae) in the Sudanian savanna from the North Eastern corner of the country. It shows 20-22 hooks 13.5-16.5 long, 14-25 testes and a distally enlarged vagina. The unknown parasites richness of very common hosts is underscored.

Highlights

  • The cestode fauna of birds of the République de Côte d’Ivoire (Ivory Coast, West Africa) is one of the better known of the continent (Mariaux, 1994), even if only a small proportion of the country’s global avian diversity of 745 species (Lepage, 2021) has been examined (Mariaux, 1994; Georgiev & Mariaux, 2007, and references therein)

  • An abundant additional material collected in the last 40 years and kept in the Natural History Museum of Geneva remains to be studied in detail

  • All seven species recognized by Mariaux & Georgiev (2018, see their table 2) differ from the present material by their hooks number and length as well as by their testes number. It belongs to a new species, Spiniglans thomassankara sp. nov

Summary

INTRODUCTION

The cestode fauna of birds of the République de Côte d’Ivoire (Ivory Coast, West Africa) is one of the better known of the continent (Mariaux, 1994), even if only a small proportion of the country’s global avian diversity of 745 species (Lepage, 2021) has been examined (Mariaux, 1994; Georgiev & Mariaux, 2007, and references therein). I report on two new dilepidid species parasitic in granivorous passerines in the genera Ploceus and Gymnoris
