NOTES ON TWO NEW SPECIES OF THE GENUS PSEU DOSTENOPHYLAX MARTYNOV (TRICHOPTERA: LIMNEPHILIDAE)

This paper deals with two new species of the genus Pseudostenophylax from provinces Sichuan and Yunnan. All type specimens are deposited in the Institute of Zoology, Academia Sinica, Beijing.1.Pseudostenophylax clavatus, sp. nov. (Fig.1)Brown. Length of forewing 12mm.This species resembles Pseudostenophylax kamba Martynov in their male genitalia. But in the new species, tergum X deeply fissured. The two divided lobes slightly oblique to the outer corners. Parameres of aedeagus curved inwards, tipped with long bristles. Inferior appendages short, broader at middle part, outer margins rounded, acute at apex.Holotype , Yunnan (Yunlong 2450m), 20-VI -1981, Liao Subai; allotype ; paratypes 1 1 , locality and date as holotype.2.Pseudostenophylax elongatus, sp. nov. (Fig.2)Dark-brown. Length of forewing 18mm.The new species is closely allied to Pseudostenophylax euphorion Schmid in the aedeagus and parameres. But it differs from the latter by: 1. tergum X widely seperated into two lobes, each lobe with three projections from lateral view;2. preanal appendages slightly flat, kidney-like, with heavy hairs in the new species.Holotype , Sichuan (Nanping, Jiuzhaigou 2300m), 6- IX -1983, Wang Shuyong; allotype , locality and date as holotype.
