Abstract: Isometrus (Reddyanus) zideki sp. n. is described from Malaysia and Indonesia (Kalimantan). Taxonomic position of Isometrus formosus Pocock, I. thurstoni Pocock and I. sankariensis Tikader & Bastawade is discussed. Isometrus formosus is placed in the nominotypical subgenus Isometrus Hemprich & Ehrenberg on the basis of distribution of pedipalpal trichobothria. The validity of the subgenera Isometrus and Reddyanus Vachon is affirmed, whereas the subgenus Closotrichus Tikader & Bastawade is considered to be a synonymum to the nominotypical subgenus. The type and only known species of the latter subgenus, I. sankariensis is transferred in the subgenus Isometrus. A check list of all species of the genus Isometrus is included. |
