Redefinition of Oulenziella Fan and Zhang, 2015

Due to the recent research ( Barbosa & Moraes 2021 ; Fan et al. 2021; this work), a redefinition of the genus Oulenziella is presented below.

FEMALE. Ocelli strongly bulging, positioned on lateral margins of prodorsal shield in a position slightly posterior to vi ; setae sce from nearly 3× to more than 8× as long as sci ; supracoxal setae scx slender and scarcely barbed; hysterosomal setae e 1 1.0 –10.0× as long as e 2 ; h 2 from nearly 4.0× to more than 12× as long as h 1 ; each tarsus (excluding pretarsus) more than 4× as long as its basal width. Genu I with solenidion σ″ 3.0–9.5× as long as σ′ ; σ on genu III small, usually not extending beyond anterior rim of segment; seta d on tarsi III and IV positioned at level of apical 1/8 to 1/6 of segment. Chaetotaxy and solenidiotaxy of legs I–IV: trochanter 1, 1, 1, 0; femora 1, 1, 0, 0; genua 2 + 2σ, 2 + 1σ, 1σ, 0; tibiae 2 + 1φ, 2 + 1φ, 1 + 1φ, 1 + 1φ; tarsi I with 4 long setae (wa, ra, la and d), 2 small apical setae (f and e) + 1 subterminal ventral spine (s) + 4 terminal ventral spines (u, p, v and q) + ω 1 + ω 2 + ω 3 + 1ε; tarsus II similar

to tarsus I but without ω 2, ω 3 and ε; tarsus III with 3 long seta w (, r and d), 2 small apical setae

(f and e) + 1 subterminal ventral spine (s) + 4 terminal ventral spines (u, p, v and q); tarsus IV with 3 long seta (w, r and d) + 1 subterminal ventral spine (s) + 2 terminal ventral spines (u, p,

v and q).

MALE. Similar to female but genital opening with an aedeagus situated between coxae IV; sclerite anterior to genital opening contiguous with medial part of apodemes IV; ventral setae 3a absent; genital setae tiny, about as long as basal alveolus; tarsi I and II (excluding pretarsi) less than 3× as long as their basal width, their apicoventral portion modified into suckers; subterminal ventral spine (s) of tarsi I–II indiscernible; terminal ventral spines p and q of tarsi

I and II blunt.

Oulenziinae currently comprises five genera. A key to genera of the subfamily (adult females) is presented as follows (Modified from Fan et al. 2015).
