Serranillus dunavani (Jeannel) , new combination.

Anillinus dunavani Jeannel (1963 a:76) . Type –male, glued on triangle and labeled / Rocky Bottom , Pickens Co., S.C., 25 Aug 1932, D.Dunavan Col. / Sassafras Mtn. 3,500 ft / in leaf mold/ TYPE / TYPE No 69542 USNM / Anillinus dunavani n.sp. (Jeannel’s handwriting) R. Jeannel det. 19 / deposited USNM.

Holotype examined. Specimen is in good condition, not damaged or dissected. This species belongs, without doubt, in Serranillus because the male holotype has three denticles on the apex of the sternum VII. But the specimen illustrated under this name by Jeannel (1963 a) and Barr (1995) is a member of Anillinus . Obviously, Jeannel had a mixture of species among the type material, and after dissecting and illustrating the Anillinus species , he erroneously labeled a specimen of a different genus and species as the holotype that was deposited in the USNM. Thus, one of the most illustrated Anillinus species has, until now, remained undescribed. That species is described herein as A. loweae Sokolov and Carlton.

This species represents the second described species of Serranillus . From the typespecies, S. jeanneli Barr , it may be distinguished by its small size ( ABL – 1.83 mm versus 2.5 to 3.2 mm, according to the description of S. jeanneli Barr ) ( Barr 1995).
