Sex Role–Dependent Behavioral and Architectural Divergence in a Jumping Spider

  Sex Role–Dependent Behavioral and Architectural Divergence in a Jumping Spider ABSTRACT Sex differences in behavior and functional traits are often attributed to differences in mating effort intensity, but the role of sex-specific parental demands remains poorly understood. Using the jumping spider Toxeus maxillosus —where males engage in mate searching and courtship without providing parental care, while females provide extended maternal care from egg attendance to offspring maturity (around 3 months)—we conducted an exploratory investigation into whether these distinct selective pressures led to divergence in spatial behaviors and nest architecture. Results revealed that males and females showed equivalent accuracy, latency, and learning-related performance in both a route-planning test under water stress and a color-pattern associative memory task. In contrast, during nest-construction assays, females built complex, multi-entrance structures that closely matched the container'...

Systematics of the Western Ghats endemic tarantula subfamily Thrigmopoeinae with the description of a new genus and four new species

Abstract
The Western Ghats are a biodiversity hotspot known for its high degree of endemism. The tarantula subfamily Thrigmopoeinae, with two genera and seven species, is endemic to the Western Ghats. A taxonomic account of the Western Ghats endemic tarantula subfamily Thrigmopoeinae is presented. The study is based on a re-examination of existing museum material and a fresh collection from across the Western Ghats. Rediagnosis of the genera Haploclastus Simon, 1892 and Thrigmopoeus Pocock, 1899, is presented with a description of a new genus and four new species. The genus Cilantica gen. nov. is proposed to accommodate Cilantica phsycadelicus comb. nov. and Cilantica kayi comb. nov., and a new species from the southern Western Ghats. Thrigmopoeinae, being endemic to the Western Ghats, a biodiversity hotspot, is a vital flagship for invertebrate conservation.
