A taxonomic study on Epedanidae from Thailand including functional aspects of male genital morphology (Opiliones, Laniatores).

ABSTRACT

The South-East Asian opilionid family Epedanidae Sørensen, 1886 has one of its strongholds in Thailand from where a multitude of genera and species have been described but the epedanid fauna of the country is still poorly known. This paper records four species from this country, three of which are new Euepedanus dashdamirovi sp. nov. (male and female), Plistobunus jaegeri sp. nov. (male and female), and Toccolus kuryi sp. nov. (male and female). Toccolus globitarsis Suzuki, 1969 was previously known only from the type locality in Thailand and is redescribed here. Functional aspects of epedanid penial morphology are highlighted.
