Guides
Leptogenys
Razorjaw Ants
Leptogenys is the most diverse genus in the ant subfamily Ponerinae, with over 260 described species distributed throughout tropical and subtropical regions worldwide. The genus exhibits remarkable morphological and behavioral diversity, ranging from large-eyed epigaeic species that forage above ground to small-eyed cryptobiotic species inhabiting soil and leaf litter. Many species possess distinctive falcate, bowed mandibles and specialize on isopod prey. Most species have ergatoid (worker-like) queens rather than typical winged queens.
Myrmecina
Mite-eating Ants
Myrmecina is a genus of ants in the subfamily Myrmicinae containing approximately 51-53 species. The genus has a broad geographic distribution spanning North America, Europe, northern Africa, India, Korea, Japan, and Australia. Species exhibit diverse reproductive strategies, including both winged gynomorphs and wingless intermorphs, with some populations demonstrating polygynous reproduction by ergatoid (worker-like) queens. The common name 'Mite-eating Ants' suggests a specialized dietary niche, though this has not been extensively documented.
