Type material.

Holotype labeled: "AL: 0.5 mi S Highland Lake Blount Co. Oct. 22, 2009 T.N. King / Blind Carabid HL - 10.22.09 Rock 1000' [handwritten] / Holotype Clivina alabama Bousquet CNC No. 24034." The holotype is in the Canadian National Collection of Insects, Ottawa, Ontario. Paratype (1 specimen) labeled: "AL: 0.5 mi S Highland Lake Blount Co. April 2009 T.N. King / Paratype Clivina alabama Bousquet." The specimen is deposited in R. Michael Brattain Collection (Lafayette, Indiana).

Etymology.

The specific epithet is a Latinized singular noun in apposition, nominative case, based on the name of the Alabama, a native American tribe who lived in southeastern United States.

Description.

With the character states of the subgenus Antroforceps as described by Ball (2001: 138-144) and the followings: Color. Body uniformly rufous, with antennae, palpi and most of legs paler. Microsculpture. Frons and clypeus without microsculpture. Pronotum without microsculpture except for small area near the posteriolateral dentiform projections. Elytra without microsculpture. Proepisternum with coarse, isodiametric meshes, sculpticells convex. Visible abdominal sternites 1-6 with coarse isodiametric meshes except medially on sternites 2-4, sculpticells convex. Head. Clypeus with anterior margin slightly concave medially, without dentiform projections laterally. Frontocly- peal suture very shallow. Frons without median fovea. Eye absent. Antennomeres 6-10 submoniliform. Mentum tooth proportionally small, apex more or less rounded, not reaching apex of lobe. Thorax. Pronotum slightly transverse (see Table 1); lateral edges shallowly crenulate; anterior angles acutely protruding; median longitudinal impression narrow along posterior half, widened along anterior half; posteriolateral dentiform projections blunt, basal projection as large as apical projection. Elytra. Lateral edges minutely crenulate on basal fourth; interval 4 convex in basal fourth; interval 5 rather flat; interval 6 and 7 carinate through most of length; interval 3 with five setigerous punctures.

SBL = 3.63-3.69 mm.

Habitat.

The two specimens were collected under rocks on a hillside in a mixed Pine/hardwood area above a stream following heavy rains (R. Michael Brattain, personal communication 2011).

Geographical distribution.

This species is currently known only from Blount County in north-central Alabama.

Remarks.

This species is structurally most similar to Clivina sasajii , which is known from nine specimens collected in Latimer County, eastern Oklahoma. The two paratypes of Clivina sasajii studied differ from those of Clivina alabama in having small eyes, the pronotum clearly elongate (see Table 1) and the elytra proportionally narrower (see Table 1), the anterior angles of the pronotum less projected, the posteriolateral dentiform projections more acute, with the basal projection smaller than the apical one, the microsculpture near the posteriolateral dentiform projections more expanded, the lateral edges of the elytra indistinctly crenulate on basal fourth, the interval 4 not convex, and the interval 6 carinate only on anterior fourth. The genitalia of the two specimens of Clivina alabama have not been extracted to preserve their integrity.

In Ball’s (2001: 144-145) key to the species of subgenus Antroforceps , Clivina alabama will key out to couplet 2. The following modification should be made to incorporate the new species:
