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 dashdamirovisp. nov. (male and female), Plistobunus jaegerisp. nov. (male and female), and Toccolus kuryisp. 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.

Apatrobus (Apatrobus) osuzuyamanus sp. nov. is described from Kyushu, western Japan (type locality: Mt. Osuzuyama [32°16'N, 131°25'E]). This species is distinguished from A. (A.) ohtsukai Morita by a larger body, a pair of small depressions on the pronotum, and the shape of the aedeagal apex. Based on a comparative study of the male genitalia of several species, the homology of the genital sclerites of the tribe Patrobini are revised and a new terminology is proposed. The implications of present results for Patrobini taxonomy are briefly discussed.

Scybalocanthon asheisp. nov. from Madre de Dios, Peru, is described based on differences in external and male genital morphology. Its diagnostic characters and an updated identification key to the species of the genus are provided as well as new distributional data for the following species: S. acrianus Silva & Valois, 2019, S. aereus (Schmidt, 1922), S. kaestneri (Balthasar, 1939) and S. pinopterus (Kirsch, 1873).

The genus Ciulfina Giglio-Tos includes a number of small tree-trunk dwelling species of praying mantids that are found through eastern Queensland and northern Australia. Three new species of Ciulfina: C. baldersoni, C. klassi and C. rentzi and one existing species C. biseriata (Westwood) are formally described on the basis of male genital morphology. A key to the identification of Ciulfina based on genital morphology is also provided.

Morphometry of 53 stingless bees of the genus Lisotrigona collected from seven places in India by using 36 morphological parameters was studied. The data set also included  morphometry data of primary types of L. cacciae, L. chandrai and L. revanai for comparison and was subjected to Factor and Canonical Discriminant analysis. All the bees collected from five places formed two distinct clusters in the Factor analysis and five clusters in Canonical Discriminant analysis. In both the methods of analysis primary types of L. cacciae, L. chandrai and L. revanai were placed well separated from each other as well as from other bees. The bees from seven places also differed from the three known species in morphometry and ratios of length and width of parts of the body. Based on these results it is concluded that Indian stingless bees of the genus Lisotrigona consists of more than one species besides L. cacciae. The action of synonymizing L. mohandasi, L. chandrai and L. revanai with L. cacciae appears arbitrary; these three species should be considered valid until supported by male genital morphology or molecular characters.
