Homotypic assortative mating is consistent across temporal scales in the spider Mecynogea lemniscata (Araneidae) Abstract Identifying patterns of size-assortative mating (SAM) indicates the direction of genetic changes in a population. A reliable method for estimating it in a population is to measure mate assortments within and between breeding seasons¸ as well as describing size variation of males and females between temporal scales to avoid Simpson’s paradox. We assessed sexual size dimorphism, the effects of ontogeny, size differences within each sex, the consistency of SAM within and between seasons, and male mate choice in the spider  Mecynogea lemniscata . We collected mating pairs in a  Eucalyptus  plantation across two breeding seasons and in four periods of the second season. We measured body mass and carapace width of spiders. Males matured earlier than females and guarded subadult partners. Although adults were larger and heavier than subadults, ontogeny did no...

Five new species of the spider genus Heteropoda Latreille, 1804 (Araneae: Sparassidae) from China


Abstract

Five new species of Heteropoda (Araneae, Sparassidae, Heteropodinae) are described from China: H. bawanglingensis sp. nov. (female; Hainan), H. dulongensis sp. nov. (male, female; Yunnan), H. hainanensis sp. nov. (male, female; Hainan), H. longa sp. nov. (female; Guizhou), and H. vaginalis sp. nov. (female; Yunnan). We provide descriptions and illustrations for each species as well as a distribution map in the current paper.
