Abstract

Although a comprehensive guide to the South African echinoid fauna was published as recently as 2017, four notable additions to the fauna have emerged since that time and are reported on here. The first South African records for Histocidarispurpurata (Thomson, 1872), Echinothrixdiadema (Linnaeus, 1758), Microcyphusrousseaui L. Agassiz, in Agassiz and Desor 1846, and Pseudoboletiamaculata Troschel, 1869 are presented. All four species have previously been recorded from the Atlantic and/or Indian Oceans and their ranges are thus extended southwards here. These additions increase the total number of echinoid species known from South Africa to 74.

Highlights

The echinoid fauna of South Africa has recently been revised by Filander and Griffiths (2014), who added 19 species to the regional fauna, and by Filander and Griffiths (2017), who provided an identification key and a guide to each of the 70 species known from the region
Additions to the echinoid fauna have been identified and are reported on here. These additions increase the number of recorded South African echinoids to 74 species, spread across 29 families
1879), belonging to this genus has previously been reported in South African waters and this remains a dubious record, as it lacks locality data (Mortensen 1932; Filander and Griffiths 2017)

Summary

Introduction

The echinoid fauna of South Africa has recently been revised by Filander and Griffiths (2014), who added 19 species to the regional fauna, and by Filander and Griffiths (2017), who provided an identification key and a guide to each of the 70 species known from the region. These additions increase the number of recorded South African echinoids to 74 species, spread across 29 families. A brief paragraph on the identification features of each species, its previously reported distributional range, and data on the new regional records are included.
