The scutum (length and width sub-equal) has mildly convex anterior lateral margins, a broadly rounded posterior margin, shallow, straight, parallel cervical grooves reaching the mid-length, and large, moderately deep punctations that are closely spaced on the anterior lateral fields
The capitulum basis is slightly over twice as wide as long with widely triangular cornua and small, deep, ovate porose areas separated by twice their diameter
The palpi feature sub-equal segments II and III, and the hypostome resembles the male's but with more basal denticles
The leg coxal spurs mirror the male's, except the spur on coxa IV is smaller than III, and spurs II and III are sub-equal in length and width.

Larva
The body measures ~0.6 x 0.4 mm
The scutum is 1.5 times as wide as long, bearing two pairs of setae and three pairs of sensilli
The capitulum basis resembles the nymph's (with cornua only apparent in mounted specimens), featuring palpi with a straight dorsal inner margin and equal contiguous margins between segments II and III, alongside a hypostome with a 2/2 dental formula of 5 denticles per file
The legs possess a very small, triangular inner spur on the basal margin of coxa I, and indefinite ridge-like spurs on coxae II and III.

Male
The body measures ~2.0 x 1.1 mm
The pyriform scutum (~1.7 x 1.2 mm) features 11 distinct festoons, deep lateral grooves extending to coxa III (enclosing the first 1–2 festoons), short, straight or slightly concave cervical grooves, and fairly numerous, noncontiguous scattered punctations
Ventrally, a large genital operculum is located between coxae II
The capitulum has a basis dorsally ~1.4 times as wide as long with narrowly pointed cornua (~1/4 the base length), triangular palpi, and a moderately stout hypostome with a 4/4 dental formula of 7–9 denticles per file
The legs possess large, widely triangular spurs on all coxae
The spur on coxa I is narrower than II, while spurs III and IV are slightly shorter than II.

Nymph
The body measures ~1.0 x 0.65 mm
The scutum is slightly broader than long, featuring cervical grooves similar to the female and four setae in each scapular area (with two anteriorly in the central field)
The capitulum has a basis ~twice as wide as long with moderately wide, tapered cornua, palpi resembling the female's (but with a greater width-to-length ratio) with a ventral spur on segment III, and an apically coronated hypostome with a 2/2 dental formula of ~7 denticles per file
The coxal spurs resemble the female's, though the spur on coxa IV is smaller and directed medially.
