The duration of the embryonic period was 14 days at room temperature. Diagnosis. Dorsal plate elongated (L/W ratio 1.65–1.75), setae Oe shorter than Hi, He, Sci and Sce; excretory pore plate much longer than wide; setae Ai relatively long and reaching posterior margin of excretory pore plate; basal segments of chelicerae nearly as long as wide; P-5 with two very long setae; II—Leg-4 with a single greatly thickened seta. Description. Idiosoma flat, dorsal plate in unengorged larvae covering almost the whole dorsum (Fig. 1), with slightly convex lateral margins, its anterior margin straight or slightly convex, posterior margin rounded, with short and punctuate scale-like patterns.
