Adults. Dorsum with AD, PD, pair of OC, four to five pairs of distinct gland pores and three to six pairs of short idiosomatic setae, pair of ds-6 on anal cone. AE, PE and GP present, may be fused to a ventral shield. PE with two to three long setae. In female genital and anal plate separated; in male plates generally fused. Genital acetabula external, all on GP, either along lateral margins or in posterior part of GP. Females with three to ten pairs of pgs, males with a larger number, arranged either close to or scatteredly around GO. Female genital sclerites with zero to five pairs of sgs, males with three pairs. Palps four-segmented, attached dorsally, P-2 with two either equal or differently sized dorsal setae (or a single (?) apical seta), P-3 with large ventral spine; P-4 basally with three setae, apically with spine and setae. Rostrum conical or elongate; apical pair of maxillary setae in about middle of rostrum, basal pair near rostral basis. Genua I and II shorter than these legs' telofemora and tibiae. Tibiae ventrally with smooth and slender or coarsely bipectinate and wide setae. Solenidion on tarsus I and II in dorsolateral position. Tarsi I to IV with 4, 4, 4, 3 dorsal and 1, 0, 0, 0 ventral setae. Arrangement and size of tines on claw I different from those on claws of following tarsi, tines of claws I rarely more delicate, often much larger than tines of the other claws. Central sclerite without distinct median claw.
Juveniles. Protonymph with one to three pairs of gac; pgs and sgs absent. Second nymphal stage with pairs of gac, pgs, sgs numbering 2–8, 2–6, 0–2, respectively.
Remarks. The subfamily includes the freshwater genera Hamohalacarus , Himejacarus , Limnohalacarus , Soldanellonyx , and Stygohalacarus but excludes Parasoldanellonyx . In this genus the solenidion on tarsus II is in a dorsomedial position.
