Morphological Keys

Stage/Sex Morphological Keys
Female
  • The mean body length is 2.79 - 3.56 mm and breadth is 1.69 - 2.23 mm, with long, narrow legs featuring sub-equal coxal spurs
  • The smooth, glossy, flat scutum shares the male's small, deep, sub-anterior cervical pits, obsolete cervical grooves, narrow lateral grooves extending to coxa III enclosing the first festoon, bulging lateral surface, 11 festoons, and shallow, small-to-medium punctations concentrated chiefly posteriorly and anterolaterally
  • The capitulum features a basis dorsally 2.5 - 2.8 times as broad as long with straight external margins, short, broadly triangular cornua (1/4 to 1/3 the base length), and small to moderately large oval or sub-oval porose areas
  • The compact palpi have 3 - 4 dorsointernal and ventrointernal setae each, and the posteriorly narrow hypostome (shorter than the palpi) has a 5/5 dental formula with 6 - 9 denticles per file.

Larva
  • The mean length is approximately 0.8 mm and breadth is 0.5 mm
  • The scutum is about 13 times as broad as long, featuring few, inconspicuous punctations and genital grooves shaped as arcs reaching to the scutal mid-length
  • The capitulum features a basis dorsally ~2 times as broad as long with straight external margins and broadly triangular cornua (~1/5 the base length), alongside broadly posteriorly salient palpi (combined breadth ~1.45 times the basis breadth) and a hypostome slightly longer than the palpi with a 2/2 dental formula of 5–7 denticles per file.

Male
  • The overall body measures 2.33–3.08 mm in length and 1.49 - 2.00 mm in width, featuring long, narrow legs with sub-equal coxal spurs and ovate spiracular plates (1.5 - 1.8 times as long as broad)
  • The smooth, glossy, flat scutum (1.26–1.31 times as long as broad) possesses 11 festoons, small, deep, sub-circular, sub-anterior cervical pits with obsolete cervical grooves, narrow distinct lateral grooves extending to coxa III to enclose the first festoon, a bulging surface lateral to the grooves, and shallow, small-to-medium punctations concentrated posteriorly and anterolaterally
  • The capitulum features a basis dorsally ~1.9 times as broad as long with straight external margins and broadly triangular, bluntly pointed cornua (~1/4 the base length)
  • The compact palpi have 5 dorsal and 3–4 ventral setae, and the posteriorly narrow hypostome (shorter than the palpi) features 5 - 6 dense rows of small hooklets and a 5/5 dental formula of 6 - 9 denticles per file.

Nymph
  • The overall body measures 1.21 -1.54 mm in length and 0.71 - 0.82 mm in width, with moderately long, narrow legs and sub-circular spiracular plates
  • The scutum is 1.1 -1.2 times as broad as long, featuring few, inconspicuous punctations and cervical grooves that converge from sub-anterior pits before diverging posteriorly beyond the scutal mid-length
  • The capitulum features a basis dorsally ~1.6 - 1.8 times as broad as long with straight external margins and elongately triangular, sharply pointed cornua (~2/3 the base length), along with broadly posteriorly salient palpi (combined breadth 1.5 times the basis breadth) and a hypostome (as long as or longer than the palpi) with a 2/2 dental formula of 7 - 8 denticles per file.
