Bimichaelia logani Uusitalo, 2025, sp. nov.

Bimichaelia logani sp. nov. (Figs. 25A–E, 26A–D) Description. Dorsum (n= 2 females, Fig. 25A, B). Length ca. 550 µm; dorsal setae with 5–6 clear cilia each and surrounded by 5–6 roundish loops of reticular primary pattern, caudal setae with elongated main cilium; prodorsum clearly reticulated, cilia of setae in, sce and vi along an elongated centre, anterior pair of sensilla ve densely ciliated, setae exp with long main cilium (like caudal setae), hard integument with large lamellae in rows or loops. Venter (Fig. 25D, E). Genital valves each with 14 genital setae; 5–6 anal setae per valve. Gnathosoma (Fig. 25C). Apical palpal solenidion supported by one eupathidion; palpal joints complete; 3 pairs of subcapitular setae. Legs (Fig. 26A–D). Solenidial formula for tarsi, tibiae, genua and femora on legs I, II, III and IV, respectively: 3B-2B-0-0, 1B-1B-1B-1B, 1C-1C-1C-1C, 1C-1B-0-0; famulus I laterodistal abaxially. Type material. Holotype female and 1 paratype female as Bimichaelia from Maple duff, Green Canyon, Cache Co., Utah, USA, 5 April 1972, G.F. Knowlton. Deposited at the Acarology Laboratory, Ohio State University, collection number AL701, holotype on slide NA32. Differential diagnosis. This species can be differentiated from other species of Bimichaelia by having sensilla ve ciliated all along while other species have the sensilla ve simple and only basally barbed, e.g. Bimichaelia pallida (Ewing) from Oregon (Fig. 23A). Bimichaelia logani also has more than 3 visible cilia on dorsal setae, and the single ceratiform solenidion on genu I. Remark. B. logani was coded as ‘ bim ’ in Uusitalo (2010). Etymology. The species name refers to the city of Logan, Utah, which is close to the type locality.
