  Thwaitesia margaritifera O. Pickard-Cambridge, 1881: A New State Record of Mirror Cob Web Spider Species (Araneae: Theridiidae) in Chhattisgarh, India Abstract This study documents the first recorded occurrence of the mirror cobweb spider Thwaitesia margaritifera O. Pickard-Cambridge, 1881 in Chhattisgarh, India, and the first record of the genus Thwaitesia in the state. Two adult female specimens were collected by hand from the foliage of a Shorea robusta tree in a forested area of Gariaband District on 27 March 2026. Live specimens were photographed, preserved in 70% ethanol, and examined using a stereo zoom microscope. Identification was based on the morphology of the carapace, abdomen, eyes, legs, spinnerets, and female genital structures, followed by comparison with published taxonomic descriptions. The specimens were characterised by a small, pale greenish-yellow cephalothorax with a dark median stripe, a large laterally compressed abdomen bearing irregular reflective scale...

FIRST RECORD OF LATRODECTUS CORALLINUS (ABALOS, 1980) (ARANEAE: THERIDIIDAE) IN PANAMA

Abstract

Latrodectus corallinus (Abalos, 1980) is identified in two provinces of Panama, where black widow spiders were previously reported under different species names. These observations provide the first confirmed evidence of L. corallinus in Central America, thereby substantially extending its known distribution range. Primera cita de Latrodectus corallinus (Abalos, 1980) (Araneae: Theridiidae) en Panama Resumen. Latrodectus corallinus (Abalos, 1980) ha sido identificado en dos provincias de Panamá, donde previamente se habían reportado arañas viuda negra bajo diferentes nombres de especies.
