“…Most of the Mexican species were described or recorded from the end of the 19 th century to the first half of the 20 th century (Banks 1898;Pickard-Cambridge 1902;Gertsch & Davis 1937, 1946 and later, only two publications by Millidge (1983Millidge ( , 1987 added another important number of species. Since then, only five species have been added to the Mexican Linyphiidae fauna (Ibarra-Núñez et al 2011;Prentice & Redak 2013;Gómez-Rodríguez et al 2014;Jiménez et al 2018;Campuzano Granados et al 2019). The discovery of a new genus recorded here suggests that the knowledge of the Mexican linyphiids is deficient in general, and particularly from habitats barely explored like the montane cloud forests.…”

A new genus and species of spider (Araneae, Linyphiidae, Erigoninae) from a tropical montane cloud forest of Mexico is described from both male and female specimens, Xim trenzado gen. et sp. nov. A phylogenetic parsimony analysis situates Xim gen. nov. as a distinct genus among the distal Erigoninae. Xim gen. nov. is sister to a clade including Ceratinopsis, Tutaibo and Sphecozone, but differs from those genera by having a high cymbium, large paracymbium, short straight embolus, male cheliceral stridulatory striae widely and evenly spaced, both sexes with a post-ocular lobe, male with two series of prolateral macrosetae on femur I, and the female by having strongly oblong, u-shaped spermathecae.

We provide information of eight new records of spiders from Central and Southern Mexico. The new records are Stemmops bicolor O. Pickard-Cambridge, Stemmops lina and Wirada mexicana Campuzano & Ibarra-Núñez from Hidalgo, Stemmops cambridgei Levi, Mazax pax Reiskind and Mazax ajax Reiskind from Campeche, Ariamnes mexicanus (Exline & Levi) from Chiapas and Homalometa nigritarsis Simon from Quintana Roo

“…While the flora of the region has been well documented (Riemann & Exequiel, 2007;Wiggins, 1980), only a tiny fraction of terrestrial arthropods containing ecologically crucial taxa have been thoroughly studied (Clark & Sankey, 1999;Due & Polis, 1986). For spiders, to date, there are about 414 described species for the whole Baja California peninsula (Jiménez et al, 2018), a number certainly due to increase with further studies (Hernández-Salgado et al, 2022). Furthermore, a trackanalysis found that the Baja California peninsula hosts 3 of 9 generalized tracks for Mexico based on agelenid spiders (Maya-Morales et al, 2018).…”

Genetic diversity and population histories of two species of Phidippus (Araneae: Salticidae) from northwestern Mexico

2023

The northwestern Mexican Baja California state is an ecologically unique area being the only part of the country with a Mediterranean ecosystem and a high species diversity and endemism for many groups. Studies on the biodiversity of the region are scarce, especially regarding ecologically important groups such as terrestrial arthropods. Even scarcer are studies on another important aspect of diversity, namely genetic diversity. Due to the paucity of information, the genetic diversity and population histories of the 2 most abundant species of Phidippus (Araneae: Salticidae) of the region are presented, based on nuclear and mitochondrial DNA data. Phidippus johnsoni, the more widespread of the 2, belonged to 1 large, panmictic population in Baja California, while P. phoenix was divided into 2 populations. Both species have high genetic diversity and estimated large population sizes, which increased during the last 150,000 years for P. johnsoni, and the last 30,000 years, after the Last Glacial Maximum for P. phoenix. This study, therefore, reinforces the importance of this area, not only for its species diversity but also for the genetic diversity found within the populations, which reflects ecological stability during the Pleistocene, allowing for the accumulation of genetic diversity through time.
