Alopecosa
Fox Spiders
Alopecosa is a genus of wolf spiders (Lycosidae) comprising approximately 160 species. These ground-dwelling spiders are predominantly Eurasian in distribution, with some species extending into North Africa and North America. Most species reach up to 2 cm in body length. Females construct burrows for egg deposition and guard their egg sacs until hatching. The genus has been subject to taxonomic revision, with species historically grouped into sibling species complexes based on morphology, though courtship behavior and molecular techniques have proven more reliable for species delimitation.
Pseudomyrmecinae
big-eyed tree ants, big-eyed ants
Pseudomyrmecinae is a subfamily of slender, hyperoptic arboreal ants comprising three genera: Pseudomyrmex (~200 species, Neotropical), Tetraponera (~100 species, Palaeotropical), and Myrcidris (two species, South America). The subfamily originated in the Palaeotropics during the Cretaceous and later dispersed to South America, where it underwent significant diversification. At least twelve independent origins of obligate mutualisms with domatia-bearing plants have occurred within this group, making it the most diverse plant-occupying ant lineage worldwide.
