Pseudotremia loomisi, n. sp.

Figs. 1–7

Types: Male holotype, male and female paratypes from Clark’s Cave, Bath Co., VIRGINIA, collected 21 May 1997 by David Hubbard.

Diagnosis: The apical and subapical spines of the MAP are both missing and there are no colpocoxite processes, while the ninth legpair telopodite appears two-segmented; a unique combination of characters.

Etymology: The species epithet honors the late H. F. Loomis, who, in a series of papers some 70 to 80 years ago, described many cave millipeds from the Appalachians, including species of Pseudotremia . Suggested vernacular name: Loomis’s Rough-backed Millipede.

Description: Male holotype about 27 mm long, 2.3 mm wide, third antennal segment 1.45 mm long. Ocelli 19 on each side, well-formed, contiguous, darkly pigmented (fig. 1). Segmental shoulders prominent; midbody metazonites with 3–5 longitudinal rugae medial to shoulders, middorsally smooth; 12–13 strong lateral striations (figs. 2, 3). Color purplish gray-brown, mottled darker anteriorly.

Gonopods (figs. 4–6) robust, angiocoxites deeply divided on each side by U-shaped sinus; MAPs relatively narrow in lateral view, lacking apical and subapical spines; LAPs long, distally divided with dorsal branch much smaller, lateral branches curve inward and cross in midline. Colpoxites deeply divided but not conspicuously mitten-shaped. Colpocoxite processes absent. Ninth legs (fig. 7) with distal segment shorter than basal, basal segment (coxoprefemur) distally swollen, proximal knobs small.

Female similar to male.

Notes: This species is evidently a troglophile. The specimens are depigmented from long preservation.
