The body measures ~3.2 mm in length (up to 9.0 mm when engorged) and 1.8 mm in width
The elongate scutum (1.25 times as long as wide) has a bluntly rounded posterior margin and punctations similar to the male's
The capitulum resembles the male's but has a basis twice as wide as long with diverging lateral margins, slightly shorter and blunter cornua, small, widely spaced, elongately oval porose areas, and a slightly broader hypostome with a 6/6, 6.5/6.5, or 7/7 dental formula
Ventrally, the highly distinctive tongue-like genital operculum is bordered laterally by labia
The legs feature widely triangular coxal spurs that are shorter than the male's, with spur III extending to or slightly beyond the basal margin, and spurs II, IV, and I progressively increasing in length in that order.

Larva
The body measures ~0.78 mm in length and 0.38 mm in width
The scutum is 1.25 times as wide as long
The capitulum has a basis slightly over twice as wide as long with cornua reduced to small, rounded marginal bulges, palpi resembling the nymph's (bearing specific dorsal/ventral setal counts on segments II and III), and a hypostome essentially like the nymph's
The legs feature short, widely rounded coxal spurs that extend slightly beyond the margin, gradually decreasing in length from coxa I to III.

Male
The body measures ~3.0 mm in length and 1.6 mm in width
The glossy scutum (~1.5 times as long as wide, widest just anterior to the spiracular plate projection) is laterally bordered by a narrow integument strip, featuring 11 festoons, short, deep, sub-parallel cervical grooves, short, shallow lateral grooves enclosing the first festoon, and rare, widely scattered, shallow, obscure punctations
The capitulum has a basis dorsally ~1.3 times as wide as long with short, widely triangular cornua (~1/3 the base length), compact palpi lacking basolateral salience, and a hypostome (as long as the palpi) with a 6/6 dental formula of ~15 narrowly elongate, closely spaced denticles per file
The robust legs possess 12–20 long setae per coxa and prominent, elongately triangular, sharply pointed coxal spurs
Spurs II and III are sub-equal, spur I is slightly longer than II and III, and spur IV is almost twice as long as II and III.

Nymph
The body measures ~1.1 mm in length and 0.5 mm in width
The scutum (slightly longer than wide) has gradually rounded margins, ovate spiracular plates, ~12 seta-bearing punctations, and cervical grooves that converge anteriorly before diverging and becoming shallower posteriorly past the mid-length
The capitulum features a basis twice as wide as long with short, widely triangular, pointed cornua, widely salient leachi-type palpi, and a hypostome with a 2/2 dental formula of ~7 large denticles per file
The legs possess short, widely triangular coxal spurs that gradually increase in length from coxa IV to I.
