  A new species of the mygalomorph spider genus Euagrus Ausserer (Araneae: Euagridae) from central Mexico and new records of E. gus Coyle from Tlaxcala Abstract  A new species of the spider genus Euagrus Ausserer, 1875 from temperate pine-oak forests in the states of Tlaxcala and Hidalgo, Mexico is described: E. pulque sp. nov. The description of the new species is based on male and female adult specimens. Additionally, Euagrus gus Coyle, 1988 is recorded for the very first time in the state of Tlaxcala. These species have sympatric distributions in La Malinche National Park, Tlaxcala. With this description, the diversity of the genus increases to 23 species, with Mexico harboring the highest diversity with 17 described species.  Valdez-Mondragón, A., Salinas-Velasco, H.

Integrative taxonomy describes a new species of the genus Dicranolasma Sørensen (Opiliones: Dicranolasmatidae) from Turkey

ABSTRACT

A new species, Dicranolasma gumushanensis sp. n., is described from the Gümüşhane Province of the northeastern region of Turkey, based on morphological and genetic evidence. The newly described species differs from similar species within the genus, particularly due to morphological characteristics such as the structure of the chelicerae and genitalia, and its molecular characteristics. A detailed description and diagnostic characteristics of the new species are provided, in addition to images of its body in dorsal view, chelicerae, pedipalps and genitalia. The nuclear (28S rRNA) and mitochondrial (COI) gene regions of the species were sequenced, revealing its phylogenetic relationships within the genus Dicranolasma.
