  DNA barcoding of scorpions from Kosovo, with the first record of Alpiscorpius dinaricus (Di Caporiacco) (Scorpiones: Euscorpiidae) ABSTRACT This study presents DNA barcoding data for Alpiscorpius dinaricus (Di Caporiacco) and Euscorpius hadzii Caporiacco. Barcode sequences were compared with publicly available reference data to support species identification, together with the evaluation of diagnostic morphological characters. Alpiscorpius dinaricus is recorded from Kosovo for the first time, representing a new national record and contributing to the knowledge of euscorpiid diversity in the region. Diagnostic illustrations of A. dinaricus are provided to facilitate reliable identification and to support future faunistic, taxonomic, and biogeographic studies. Euscorpius hadzii , previously known only from Prizren district, is now reported also from Bjeshkët e Nemuna Mountains (Western Kosovo).

Spider diversity (Arachnida: Araneae) in two different coffee management systems and surrounding tropical forest during two contrasting seasons in Oaxaca, Mexico

ABSTRACT

This study focuses on species richness, abundance, diversity, and seasonal variation of spiders in two coffee plantations with different crop management and a portion of tropical forest in two municipalities of  La  Costa region of  Oaxaca,  Mexico,  using manual collection,  foliage beating   and pitfall traps.   We collected   2,210   spiders belonging to  35  families,  100  genera  and  146  species.  The inventory includes  51  new species records for Oaxaca. Completeness values for two estimators indicate that the level of representation of inventories range from 68.25% to 78.44%, and the proportion of singletons range from 33.72% to  38.14%.  Spider abundance in the rainy season was significantly lower than during the dry season.  Spider abundance in the  Tropical  Forest was significantly lower than Monoculture site with the foliage beating method. Polyculture was the site with the lowest spider abundance with the pitfall traps. Rarefaction curves did not show significant differences in species richness between the sites and seasons. Hutcheson t-test showed that spider diversity was significantly lower in Monoculture than Tropical Forest during the rainy season. This study contributes to the knowledge of the arachnofauna of Mexico and particularly of the state of Oaxaca.
