|Title||Bunochelis altenai, a new harvestman from the Canary Islands (Opiliones, Phalangiidae)|
|Abstract||In the spring of 1947, during his stay on the Canary Islands, Dr. C. O. van Regteren Altena collected a small number of Opiliones on the Island of Tenerife, which he kindly permitted me to study. Most of these specimens are juveniles that could not be identified. Three species are, however, represented by adult specimens. I identified two of these with Metadasylobus fuscoannulatus (Simon) (localities : Barranco Andura (or Andola), south of Realejo, 17-III-1947, 1 ♂, 3 ♀ ♀; Las Mercedes, about 650 m, 22-III-1947, 1 ♂), and Bunochelis longipes Roewer (localities: La Paz, near Puerto Orotava, 12-III-1947, 1 ♂; Icod el Alto, about 500 m, 25-III-1947, 1 ♂) respectively.|
The third species appeared, however, to be new to science; it is dedicated to its collector. I classify it with Bunochelis, a genus in which the first joint of the chelicerae of the male has a dorsal protuberance. Bunochelis altenai nov. spec. is described and figured in the present paper, whilst in a key a comparison is made with other species of the genus. I am greatly indebted to Prof. Dr. C. F. Roewer for his kind assistance in the study of the new species. The material is preserved in the Rijksmuseum van Natuurlijke Historie, Leiden.
Bunochelis altenai nov. spec. (fig. 1a, b, c) Material. Barranco Andura (or Andola), south of Realejo Alto, Tenerife, Canary Islands, 17-III 1947, 1 ♂ (holotype); 1 subadult ♂ (paratype).
Description. Length of the male (without chelicerae) : 4.2 mm.
