Type species: Hiemalidactylus eileenae sp. nov.

Etymology: The genus is named after the coloration of its face; a contrasting dark and light pattern, looking like the specimen just came in from a wintery, snowy walk (from Latin “hiemalis” meaning “wintery”).

Diagnosis: Distinct facial coloration consisting of highly contrasting darker and lighter areas, including the compound eye. Protibia with three long dactyls. Metafemur inflated along entire length, but comparably slender for a Tridactylidae (length/width ratio 3.4). Metatibia with few small denticles. Subapical and apical spurs approximately of equal length. Metatarsus pointed apically, without denticular process, hairs, or spines. Cerci two-segmented, basal segment longer than distal segment and tapering consistently with no clear constriction between segments. Both segments with sparse long setae. Paraproct elongated and prominent, narrow triangular and reaching almost length of basal cercus segment. Paraproct without paraproctal processes. Subgenital plate not elongated (not visible).
