  A new species and a new record of Zoicinae Lehtinen & Hippa, 1979 (Araneae: Lycosidae) from Sumatra Island, with notes on miniaturization in wolf spiders Abstract A new species of wolf spider, Zoica veloxilla sp. nov., from Sumatra (Indonesia) is described based on both sexes. Lysania pygmaea Thorell, 1890 is recorded from Sumatra for the first time, and its male is illustrated and redescribed. A distribution map for Zoica and Lysania is provided. The problem of miniaturization in wolf spiders is briefly discussed. Based on an analysis of the literature, 32 minute species of wolf spiders in four subfamilies and eleven genera have been reported. The smallest wolf spider known worldwide seems to be Zoica minuta (McKay, 1979) from Australia. Omelko, M.M. & Fomichev, A.A.

New insights into Damarchus: a new species and gynandromorph description from Thailand (Araneae: Bemmeridae)

Abstract

The genus Damarchus Thorell, 1891, represents a relatively neglected group of mygalomorph spiders distributed across several Asian countries, including India, Indonesia, Malaysia, Myanmar, Singapore, and Thailand. This study describes a new species, Damarchus inazuma sp. nov., discovered in Thailand. The male D. inazuma is identified by the presence of three diminutive spines on the tibial apophysis, whereas the female is characterized by an elongated spermathecal stalk that exhibits an inward curvature. Additionally, we report the identification of a gynandromorph specimen of D. inazuma, marking the first recorded instance of this condition within the family Bemmeridae.
