Redescription

Larva (N = 20) – Dorsal surface of idiosoma with 25–39 barbed and pointed setae (fD), scutum pentagonal, uniformly punctate and longer than wide; lateral parts of anterior border slightly concave, median part convex; anteromedian border of scutum convex; scutum with two pairs of sensilla and three pairs of normal setae (scutalae). Scutalae (AL, ML and PL) barbed and pointed. Posterior sensilla (PSens) longer than anterior sensilla (ASens) (1.15–1.43 ×), ASens and PSens with short barbs in distal 1/3. One eye on each side of idiosoma, 30 in diameter ( Fig. 1 ).

Gnathosoma with one pair of smooth and parsnip-shaped galealae (cs) and two pairs of hypostomalae (as, bs); as smooth and bs barbed, bs> as (at least 2.5–3.6 ×) ( Fig. 3 ). Palpfemur and palpgenu each with one barbed seta. Palptibia with three barbed setae. Palptarsus with five setae, one solenidion and one eupathidium. Palpal setal formula: 0-B-B-BBB 2 -BBBNNωζ. Cheliceral basis punctate. Cheliceral blade with a subterminal tooth (like most of Charletonia species). Supracoxal seta peg-like (ep) 4–5 long ( Fig. 3 ). Measurements are given in Table 1 .

Ventral surface of idiosoma with 19–29 barbed and pointed setae behind coxae III (fV). Sternalae 1a (between coxae I), 2a (between coxae II) and 3a (two setae between coxae II and III) barbed and pointed ( Fig. 2 ); NDV = 37 + 26 = 63 (holotype). Coxa I with one seta (1b); coxae II and III, each with two setae (2b 1, 2b 2; 3b 1, 3b 2). All coxalae barbed and pointed. Seta lb distinctly longer than setae 2b and 3b ( Fig. 2 ). Coxae I with a peg-like supracoxal seta (eI) 4 long.

Leg segmentation formula: 7–7–7. Leg setal formula: Leg I: Ta – 1ω, 1ε, 2ζ, 1 z, 29n (specimens c, L 29/ R 28 ; k, L 28/ R 28 and q, L 28); Ti – 2φ, 1κ, 1 z, 18n; Ge – 1σ, 1κ, 12n (specimen b, L 12/ R 13 ); TFe – 5n, BFe – 4n; Tr – 1n.
