Alobates pensylvanicus
false mealworm beetle
Alobates pensylvanicus, commonly known as the false mealworm beetle, is a species of darkling beetle in the family Tenebrionidae. It is native to North America and has been documented as a host for parasitic mite larvae, specifically Neotrombidium beeri, which occupy the subelytral space of adult beetles. The species is part of the diverse tenebrionid fauna associated with decaying organic matter and forest floor habitats.
Erginulus
Erginulus is a genus of harvestmen in the family Cosmetidae, described by Roewer in 1912 with the type species Erginus serratipes. The genus comprises 29 described species distributed primarily in eastern Mexico and northern Central America, with a few outlying records. Species are medium to large-sized cosmetid harvestmen, with Erginulus clavotibialis in Belize reaching 6–7.5 mm adult body length. Males exhibit sexual dimorphism with two distinct morphotypes (α and β males), characterized by enlarged chelicerae and armed leg IV with protuberances or spines; females have smaller chelicerae and unarmed legs.
Geotrupidae
Earth-boring beetles, Earth-boring dung beetles, Dor beetles
Geotrupidae is a family of beetles in the order Coleoptera, commonly called earth-boring dung beetles or dor beetles. Adults excavate burrows in soil to lay eggs, typically provisioning nests with leaf litter (often moldy) rather than dung, though some species are coprophagous. The family contains over 600 species in about 30 genera across two subfamilies: Geotrupinae and Taurocerastinae. Formerly classified as a subfamily of Scarabaeidae, Geotrupidae was elevated to family status based on phylogenetic evidence. Some species communicate via stridulation, and burrows can exceed 2 meters in depth.
Mycetina
handsome fungus beetles
Mycetina is a genus of handsome fungus beetles in the family Endomychidae, established by Mulsant in 1846. The genus comprises approximately 11 described species distributed across the Northern Hemisphere, with records from Europe, North America, and the Eastern Palearctic. Members are associated with fungal habitats and serve as hosts for phoretic mites.
Syntomus
Syntomus is a genus of ground beetles in the family Carabidae, subfamily Lebiinae. The genus contains at least 50 described species distributed across the Palearctic region and North America. Members are small to minute beetles, with at least one species (Syntomus lateralis) documented as a host for parasitic mites in the family Podapolipidae.
