THE SUBTERRANEAN ASELLIDS OF MARYLAND: DESCRIPTION OF CAECIDOTEA NORDENI, NEW SPECIES, AND NEW RECORDS OF C. HOLSINGERI AND C. FRANZI (CRUSTACEA: MALACOSTRACA: ISOPODA)
JOURNAL OF CAVE AND KARST STUDIES(2010)
摘要
Five species of subterranean asellid are known from Maryland: Caecidotea pricei, C. franzi, C. holsingeri, C. mausi and C. vandeli. Caecidotea nordeni, n. sp. is a subterranean species described from Washington Co., Maryland and assigned to the hobbsi Group. A new locality for C. franzi in Kentucky is presented. This species was previously known from two caves in Maryland and Pennsylvania. The newly discovered population represents a range extension of over 400 km. The male pleopod 2 morphology of specimens from a Maryland population of the subterranean asellid C. holsingeri is compared with populations from three caves in West Virginia. The range of C holsingeri extends from eastern West Virginia and adjacent Virginia to Garrett Co., Maryland.
