  Testing the Limits of Morphology: A Comprehensive Morphometric Study of the Sister Lineages Lasiocyano Galleti-Lima, Hamilton, Borges and Guadanucci, 2023 and Lasiodora C. L. Koch, 1850 (Theraphosidae, Mygalomorphae) ABSTRACT Morphological conservatism and homoplasy pose significant challenges for the systematics of mygalomorph spiders, limiting the number of reliable morphological characters available for species identification, particularly in Theraphosidae. Closely related taxa frequently display high phenotypic similarity, which limits the resolution of morphology-based approaches. In this study, we conducted the most extensive morphometric analysis to date within Theraphosidae, with the objective of explicitly testing how much morphological information is retained within the  Lasiocyano sazimai  and  Lasiodora  lineage. We applied a morphometric framework combining linear morphometry and geometric morphometry, including multivariate statistics, discrimina...

New data on the spider fauna of Iran (Arachnida: Araneae), Part XI.

Abstract
New faunistic and taxonomic data are provided for 18 families of Iranian spiders. Four species, Cryptodrassus liyanicus Zamani & Marusik, sp. n. (♀, Bushehr Province; Gnaphosidae), Mesiotelus khorasanicus Zamani & Marusik, sp. n. (♂♀, Razavi Khorasan Province; Liocranidae), Nurscia minuscula Zamani & Marusik, sp. n. (♀, West Azerbaijan Province; Titanoecidae) and Talanites farsensis Zamani & Marusik, sp. n. (♀, Fars Province; Gnaphosidae), are described as new to science. Clubiona liachviana Mcheidze, 1997 stat. reval. (Clubionidae) is removed from the synonymy with C. alpicola Kulczyński, 1882 and is reported from Armenia, Azerbaijan, Iran and Turkmenistan for the first time; additionally, its previously unknown male is described. The genus Kishidaia Yaginuma, 1960 (Gnaphosidae) and a total of 10 species are recorded in Iran for the first time, and new provincial records are provided for 20 species. Two specimens from Iraq are also reported. Considering the results of this paper, the number of species of spiders known from Iran is increased to 980 species in 329 genera.
