On some Indian species of Aphelinidae,with a description of a new Coccophagus (Hymenoptera: Chalcidoidea)

Summary

The Philippine cruise of the U.S. Fisheries Steamer Albatross 1907–10 collected 61 species of spider crabs from the Philippine Islands bringing the total number of species known from the area to 71; 28 new species were described by Rathbun and the present report records 19 species not previously known from the area; included are nine widespread Indo-west Pacific forms, four previously known from Japan and four Indian Ocean species.

Hyastenus sebae White is renamed H. whitei and the former name is applied to H. oryx A. Milne Edwards. Hyastenus tuberculosus Rathbun is confirmed as a synonym of H. convexus Miers, Platymaia remifera Rathbun is reduced to synonomy with P. wyvillethomsoni Miers and Chorilia sphenocarcinoides Rathbun is transferred to the genus Sphenocarcinus.

The majority of species (51) occur around the central and southern islands of the archipelago and most of these (35 speciesl occur at varying depths on the continental shelf. Twelve species occur intertidally and 21 species are known from depths over 100 fms, some occurring as deep as 800 fms.

The spider crab fauna is clearly part of the Indo-west Pacific, 25 species being widespread ones; 26 species are shared with Japan, 24 with Australia and 31 with the Indian Ocean. However, 20 species appear to be confined to the Philippine Islands. The relationships of the Philippine fauna with that of the rest of Indonesia is not yet clear
