Description
Summary:Genus Unionicola Haldeman, 1842 Unionicola (Pentatax) figuralis (Koch, 1836) (Figs 1–11) Material examined. Larvae (n = 8) were reared from single female collected in D’yakonovskoe Lake, Ust’- Kamchatsky District, Kamchatka Province, 8 August 1983. 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. All four pairs of setae on the dorsal plate thin and approximately equal in length. ... : Published as part of Tuzovskij, Petr V., 2012, Larval morphology of Unionicola figuralis (Koch, 1836), Neumania imitata Koenike, 1908, and N. spinipes (Müller, 1776) (Acari: Hydrachnidia: Unionicolidae), pp. 43-56 in Zootaxa 3506 on pages 44-47, DOI: 10.5281/zenodo.282494 ...
