Diagnosis
Diagnosis: Dorsal shield bearing marginally pilose setae and ornamented with oval pits. Genital shield of female long and linguliform. Sternal setae St1-St3 long, St4 short, ventral setae v2, v6, v7, v8 and ad long. Position of ventral setae unique within subgenus Circobaloghia.
Description
Description of female: Length of idiosoma 260, width 220 (n=2). Shape circular, posterior margin rounded, color reddish brown. Dorsal side of idiosoma (Fig. 23): Marginal and dorsal shields completely fused, surface with small oval pits (Fig. 24). Dorsal setae long (about 31-39) and marginally pilose (Fig. 24). Ventral side of idiosoma (Fig. 25): Sternal shield with some oval pits in anterior area. All sternal setae smooth, needle-like, St1, St2 and St3 long (about 22-25), St4 short (about 7-8). St1 situated close to anterior margin of sternal shield, St2 at level of anterior margins of coxae II, St3 at level of posterior margins of coxae III, St4 close to St3. Ventral setae smooth, long (about 22-29) and needlelike. V2 placed close to basal edges of genital shield, V7 and V8 close to posterior end of pedofossae IV. V6 situated between V7 and V2, setae ad at level of anal opening and between anal opening and V7. One pair of lyrifissures situated close to anal opening. Ventral shield without sculptural pattern. Stigmata situated between coxae II and III. Prestigmatid part of peritremes hookshaped, poststigmatid part short. Genital shield long and linguliform, surface with pits, its apical margin rounded. Tritosternum narrow at base, tritosternal laciniae divided into four branches. Pedofossae deep, their surface smooth, separated furrows for tarsi IV present.
Gnathosoma (Fig. 26): Corniculi horn-like, internal malae as long as corniculi and smooth. Hypostomal setae as follows: h1 long (about 33-35), smooth and needlelike; h2 and h3 needle-like and shorter (about 16-21); h4 short and marginally serrate (about 14-15 μm). Palpal setae needle-like and smooth, except for a bifurcated seta on ventral side of palpal trochanter. Apical part of epistome weakly pilose. Fixed digit of chelicera long, apically rounded and bearing a lateral pit-like sensory organ. Movable digit shorter, both digit without tooth. Internal sclerotized node present (Fig. 28). Legs (Figs 29-32): First leg without ambulacral claws; all setae on legs smooth and needle-like. Description of male: Length of idiosoma 370-410, width 340-370 (n=5). Dorsal side of idiosoma: Ornamentation and chaetotaxy of dorsal shield as in female. Ventral side of idiosoma (Fig. 33): Four pairs of sternal setae situated anterior to and one pair posterior to genital shield, these setae smooth, needle-like and long (22-25 long). St1 situated near anterior margin of sternal shield, St2 at level of posterior margin of coxae II, St3 at level of central area of coxae III, St4 at level of anterior margin of coxae IV, St5 near posterior margin of genital shield. One pair of lyrifissures situated near St5 on sternal shield. Surface of sternal shield with numerous oval pits anterior and posterior to genital shield. Surface of ventral shield, and shape and size of ventral setae as in female. Genital shield egg-like and situated between coxae IV.
Larva and nymphs unknown.
