The shield-shaped scutum (widest at the apical fourth) features anterior punctations similar to the male and cervical grooves consisting of small, deep, sub-marginal anterior pits transitioning into shallow, parallel grooves reaching the scutal mid-length
The capitulum has a slightly wider basis than the male and discrete, small, widely spaced, sub-circular porose areas, while the palpi and hypostome remain essentially the same
Ventrally, the distinctive genital operculum is triangular with a truncate apex and a shallow, depressed sub-circular central area
The legs feature coxal spurs similar to the male, except the spur on coxa IV is shorter.

Larva
The total body length is ~0.7 mm and breadth 0.5 mm
The scutum is ~1.5 times as broad as long, featuring rounded scapulae, an anterior emargination and margin similar to the nymph, and a margin that is concave from the mid-length and posteriorly narrow and bluntly rounded
The capitulum basis is essentially like the nymph's but features a more convex posteroventral ridge and lacks adjacent setae, while the palpi are similar to the nymph's except for slightly narrower posterior margins on segment II
The hypostome resembles the nymph's but has ~6 denticles per file
The long legs feature a broadly triangular spur on coxa I extending almost to the anterior margin of segment II, and broadly rounded ridges serving as spurs on coxae II and III.

Male
The mean body length is ~3.2 mm and width 2.1 mm
The scutum is laterally bordered with indistinct lateral grooves (short, shallow depressions extending from the anterior festoon to coxa II or III), short, deep, sub-parallel cervical grooves, moderately numerous, shallow, discrete, irregularly distributed punctations, and 11 festoons
The capitulum features a basis dorsally ~1.6 times as wide as long with widely triangular, bluntly pointed cornua (~1/4 the base length), compact palpi lacking basolateral salience, and a hypostome (as long as the palpi) with a 5/5 dental formula of 10–12 denticles per file (the anterior and posterior 2–3 are smallest)
The legs possess prominent coxal spurs: coxa I has a narrowly elongate, bluntly pointed, peg-like spur overlapping the apical margin of coxa II
Coxae II and III have sub-equal, short, widely triangular median spurs that do not overlap the following coxa
And coxa IV has a shorter triangular spur near the inner margin.

Nymph
The overall body measures ~1.5 mm in length and 0.8 mm in breadth
The scutum is ~1.3 times as broad as long with few, obscure punctations and narrow, linear, parallel cervical grooves reaching the mid-length
The capitulum features a basis dorsally twice as broad as long with straight margins and broadly triangular cornua (~1/2 the base length), broadly campanulate palpi (combined breadth ~1.38 times the basis breadth), and a hypostome longer than the palpi (~2.3 times as long as broad) with a 2/2 dental formula of 7–8 denticles per file (1–2 extra denticles may be inserted anteriorly and posteriorly)
The long legs have a triangular spur on coxa I reaching the anterior margin of coxa II, and broadly triangular spurs on coxae II to IV that extend well beyond the posterior margin and successively decrease in size.
