Spiders of the genus Micaria are ground‐living mimics of ants. Species delineation in these
spiders is challenging, mainly because of exceptional high levels of intraspecific variation …

Until recently, Loxosceles rufescens was the only species known from a geographic range
including Northern Africa, Mediterranean Europe and the Middle East. Rich Loxosceles …

Species delimitation is fundamental for biological studies, yet precise delimitation is not an
easy task, and every involved approach has an inherent failure rate. Integrative taxonomy, a …

Generally, sexual repertoire within a species is conserved, but frequencies of occurrence of
sexual behavioral acts often vary, and wide geographic distributions may favor these …

This study summarizes the taxonomic treatment of the camel spider genus Chanbria Muma,
1951. Taking an integrative taxonomic approach incorporating phylogenomic …

Sexually deceptive Chiloglottis orchids lure their male thynnine wasp pollinators to the
flower by emitting semiochemicals that mimic the specific sex pheromone of the wasp …

Filistatidae is one of the most phylogenetically enigmatic spider groups, and the genus
Kukulcania Lehtinen includes the commonest representatives of the family. Its type species …

Understanding what drives the existing phenotypic variability has been a major topic of
interest for biologists for generations. However, the study of the phenotype may not be …

Abstract Theory predicts that costly secondary sexual traits will evolve heightened condition
dependence, and many studies have reported strong condition dependence of signal and …

The dung beetles Amidorus obscurus and A. immaturus are nearly indistinguishable, being
characterized by a marked constancy in external morphological traits and little sexual …
