Anillinus kovariki Sokolov and Carlton , new species

( Fig. 28 , Map fig. 39)

Holotype ( FSCA). Male labeled / Florida, Jefferson Co., Monticello , 3.5 mi NW, 2.5 mi W Rt-259 on West Lake rd. (Mays Pond), 18–27-1-1999, P.Skelley & P.Kovarik, Geomys burrow pitfall / HOLOTYPE, Anillinus kovariki Sokolov and Carlton , des. 2003/.

Paratypes. None.

Specific Epithet. This species is named for Peter Kovarik (Columbus, OH) in honor of his contributions to Coleoptera systematics and his research on the faunas of pocket gopher burrows.

Description. Large-sized species (ABL ¼ 2.66 mm). Habitus markedly convex, ovoid (WE/ ABL 0.37), head relatively narrow (WH/WPm 0.67), pronotum extremely wide (WPm/WE 0.87). Color of body brunneorufous, appendages testaceous. Dorsal microsculpture effaced on pronotal disc and mostly effaced on head, where it covers only vertex.

Pronotum markedly convex, markedly transverse (WPm/LP 1.37), with margins rectilinear and moderately constricted posteriad (WPm/WPp 1.26). Anterior angles evident, slightly prominent. Posterior angles slightly obtuse (1088). Width between posterior angles much greater than between anterior angles (WPa/WPp 0.90).

Elytra moderately convex, moderately depressed along suture, of normal length (LE/ABL 0.57), with traces of 4–5 interneurs. Humeri moderately prominent, slightly rounded. Vestiture of elytra relatively short (less than one-fourth length of discal setae).

Males with metafemora modified; bearing a small sharp denticulate projection along posterior margin in apical third.

Females unknown.

Median lobe ( Fig. 28 ) large, evenly arcuate, with enlarged rounded apex bent in dorsoventral aspect. Apex with a small incision at the right side. Both sides of apical ostium modified to form walls, the larger bearing several setae and a narrow appendix, united at apex. Thus, apex of median lobe bears a small incision at the right side and in dorsal view the apex has an asymmetrical ‘‘left palm’’ contour with long ‘‘thumb.’’ Internal sac with copulatory pieces of dorsal and ventral sclerites. Dorsal sclerites small, arcuate, in form of a blade-like structure. Ventral sclerite formed from a small angulate plate. Spines of internal sac absent.

Distribution. Known from the type locality in Jefferson Co., Florida ( Fig. 39).

Habitat. The holotype was collected in a pocket gopher burrow. Peter Kovarik and Paul Skelley have collected extensively from this habitat in Florida but have taken only one specimen of this species. Probably the species is subterranean in areas where pocket gophers occur and was accidentally collected in the burrow trap .

Differential Diagnosis. Anillinus kovariki is a single member of ovoid species without microsculpture on the pronotum and mostly effaced microsculpture on the head ( Table 2, group VII of litter species). The large size of the beetle, large median lobe, and enlarged lateral walls of the aedeagal apex set this species apart from all other members of the genus for which males are known.

This species is allopatric with respect to other described species of Anillinus . From its geographically closest congeners it differs by its large size, and by its transverse and smooth pronotum, in addition to features mentioned in the key. From A. dohrni , described from Florida without precise locality information, it differs by its larger size ( A. dohrni : length— 1.50 mm, width— 0.50 mm; A. kovariki : length— 2.66 mm, width— 0.98 mm).
