Records of Psocidae: Psocinae (Insecta: Psocoptera) from Sumatra, Indonesia

摘要

Twelve species of Psocidae: Psocinae are recorded from Sumatra. Two, Psocidus strictus Thornton and Atrichadenotecnum umbratum (New & Thornton), are the first records from Indonesia, whilst all others were known previously from eastern Indonesia. Distributions and affinities are discussed. In this paper we record the species of Psocidae: Psocinae (other than of Trichadenotecnum Enderlein, see below) collected in recent extensive surveys of Psocoptera in Sumatra, the large western island of Indonesia,a region until recently very poorly explored for these insects. Records are presented to augment distributional knowledge of these taxa in Indonesia and that of the faunal transitions beween western Indonesia and peninsular Malaysia. Most of the speciesrecorded here were known previously from Java (Endang et al. 2002). All are new for Sumatra, and it is notable that further new species have not been discovered in the Sumatran collections, other than for Trichadenotecnum, which has diversified considerably in the region with 33 species recorded from Indonesia (Endang & New 2005, in which Sumatran records are summarised). This contrasts markedly with some other Psocidae (such as the subfamily Amphigerontiinae) in which many of the species from these same collections were previously undescribed (Endang & New 2010).
