  Two New Lynx Spider Species of Hamadruas and Oxyopes and the First Record of Hamadruas Thorell, 1887 (Araneae: Oxyopidae) from Wai, Maharashtra, India Abstract The present study reports two oxyopid spider species from Wai, Satara District, Maharashtra, India, based on morphological examination of specimens collected from the Kisan Veer Mahavidyalaya campus. The specimens were collected using hand-collection and sweep-net methods, preserved in 70% ethanol, and examined under a stereotrinocular microscope. Diagnostic structures, including the female epigyne and male palp, were studied after dissection, and distribution maps were prepared using QGIS. Hamadruas kvmensis sp. nov. is characterised by distinct dark elongated spermathecal lobes, a rounded central region forming the median fertilisation duct, curved copulatory ducts, and a male palp with an elongated curved cymbium, large bulb, prominent tegulum, slender embolus, conductor, tibial apophysis and sensory setae. Oxyopes wai...

Resurrection of Grammostola australis (Araneae: Theraphosidae) after seven decades: integrating molecular data, morphology, and distribution

Abstract

The name Grammostola australis Gerschman et Schiapelli, 1948, syn. resurr. is herein resurrected from synonymy with G. inermis Mello-Leitão, 1941, based on morphological and molecular evidence. The holotypes of both species are redescribed, and the female of G. australis is described for the first time. Diagnoses of these species are also provided. Phylogenetic analyses recovered G. inermis as a distinct lineage from G. australis, suggesting that both species are more closely related to Brazilian and Uruguayan species of the genus Grammostola Simon, 1892, than to other Argentinean species. Similarly, Chilean species appear distinct from other Grammostola species, indicating that the Andes act as a geographical barrier.
