Apomastus
Apomastus is a genus of mygalomorph spiders in the family Euctenizidae, endemic to southern California and described in 2002. The genus contains only two species, A. kristenae and A. schlingeri, both restricted to the Los Angeles Basin and surrounding hills. Females of both species are morphologically indistinguishable, requiring molecular or male morphological analysis for identification. The genus occupies habitat highly vulnerable to urban development.
Comaldessus stygius
Comal Springs Diving Beetle
Comaldessus stygius is a small diving beetle in the family Dytiscidae, described from Comal Springs in Texas. It belongs to a genus of minute beetles adapted to spring and groundwater habitats. The species is known from very few records and is considered rare.
Lycaena dospassosi
maritime copper, saltmarsh copper
Lycaena dospassosi is a small copper butterfly endemic to eastern Canada, restricted to coastal saltmarsh habitats where its larval foodplant Argentina egedei grows. First described in 1940 by James McDunnough, it was originally treated as a subspecies of L. dorcas but is now recognized as a valid species. The butterfly has a wingspan of 25–31 mm and flies from late July to mid-August. Adults nectar on sea lavender (Limonium carolinianum).
Melanoplus indicifer
spinecercus short-wing grasshopper, east coast scrub grasshopper
Melanoplus indicifer is a species of spur-throated grasshopper endemic to a restricted range in Florida. It inhabits scrub habitats on the Atlantic Coastal Ridge in Palm Beach County. The species is characterized by short wings, a trait reflected in one of its common names. Its limited distribution makes it vulnerable to habitat loss from development and fire suppression.
