Abstract

Four species of Tapeinochilos have been described from material collected in Wallacea. We designate the lectotype of the genus, T. pungens, which was synonymized with T. ananassae in 1917 and add here T. teysmannianus as another synonym. The type of T. koordersianus from Sulawesi has been rediscovered at Herbarium Bogoriense and is identified as Etlingera heliconiifolia (Zingiberaceae), the combination of which is published here. After establishing that T. koordersianus applies to a species of Etlingera, there is no evidence that any species of Tapeinochilos occurs in the island of Sulawesi; the westernmost presence of the genus being in the Sula Islands represented by T. ananassae, the only species thus presently occurring in Wallacea.

Highlights

Tapeinochilos Miq. is a genus of about 16 species found from eastern Indonesia and New Guinea eastwards into the Pacific (Solomon Islands and Vanuatu) and southwards to Queensland, Australia (Gideon 1996)
We examine all names of Tapeinochilos based on material collected in Wallacea, namely T. ananassae (Hassk.) K.Schum., T. koordersianus Ridl., T. pungens, and T. teysmannianus Warb
Valeton (1917) first suggested that T. pungens is a synonym of T. ananassae and this was followed by Smith in the Flora of Australia (Smith 1987), but the other two names have not been dealt with until now

Summary

Introduction

Tapeinochilos Miq. is a genus of about 16 species found from eastern Indonesia and New Guinea eastwards into the Pacific (Solomon Islands and Vanuatu) and southwards to Queensland, Australia (Gideon 1996). We examine all names of Tapeinochilos based on material collected in Wallacea, namely T. ananassae (Hassk.) K.Schum., T. koordersianus Ridl., T. pungens, and T. teysmannianus Warb.
