Description

Female (holotype)

BODY. Length 1.38 mm (paratype 1.40 mm); uniformly amber color (possibly faded). Dorsum narrow, elongated (almost twice as long as wide) ( Fig. 18A ); anterior margin of prosoma with shallow notch; anterolateral margins short, sinuate; posterior margin of opisthosoma rounded. Ozophores slightly longer than wide at their bases, laterally orientated (type 1). Integument densely granulated with oval to slightly elongated first rank granules ( Fig. 19A–C ).

CHELICERAE ( Fig. 20D ). Stocky; basal article 0.53 mm long; second article 0.51 mm long; smooth with slightly sparsely granulated ventral process of basal article; on fiXed finger 7, on movable finger 6 tightly spaced teeth.

PEDIPALPS ( Fig. 20E ). Of normal proportions, 0.93 mm long without coxa and apotele; trochanter as long as patella; tarsus as long as tibia; apotele elongated.

VENTRAL PROSOMAL COMPLEX ( Fig. 18C ). Coxal lobes II are twice as wide anteriorly as at poisterior end. Coxal lobes III short, three times as wide as long.

LEGS. Metatarsi elongated. Basitarsi I with ornamented astragalus occupying less than half of their length. Telotarsus I L/W ratio: 3; telotarsus II L/W ratio: 2.5 ( Fig. 20A–B ). Sensory structure – “subapical process” present on telotarsi I–II, large, thick, not tapering toward distal portion; almost laid flat on surface of telotarsi. Telotarsus IV relatively short, slightly longer than basitarsus ( Fig. 20C ). Claws II with two short denticles; claws IV with a short denticle; claws III with a row of 4 prolateral and 2 short retrolateral dentlices; two basal retrolateral denticles very short, distal two elongated. Measurements of legs (without coxae and claws, in mm): I 1.47; II 1.17; III 0.98; IV 1.22.

OVIPOSITOR. Apical lobes short ( Fig. 12B ) two times as long as terminal article. Terminal article as long as wide at its base. Receptacle orifices located subterminally on apical lobes. Receptacles of saccate form. Terminal setae slightly longer than apical lobes. Subterminal mediodistal setae half as long as terminal ones.

Male

Unknown.
