Etymology. The specific epithet honors Janet Ciegler, avocational coleopterist, author, and regular volunteer in the effort to document the beetle fauna of Great Smoky Mountains National Park.

Description. Small to medium-sized for genus (ABL range 1.48–1.76mm, mean 1.65± 0.081 mm, n=20). Habitus ( Fig. 1 View FIGURES 1 – 2 ) markedly convex, ovoid (WE/ABL 0.39±0.011), head normally proportioned for genus (WH/ WPm 0.72±0.022), pronotum narrow compared to elytra (WPm/WE 0.77±0.014). Body color dark, from dark brunneous to brunneorufous, appendages much lighter, testaceous. Microsculpture distinct across dorsal surface of head and pronotum.

Pronotum moderately convex and transverse (WPm/LP 1.23±0.037), with margins rectilinear and moderately constricted posteriad (WPm/WPp 1.28±0.042). Anterior angles evident, slightly prominent. Posterior angles slightly obtuse (105–110°). Width between posterior angles greater than between anterior angles (WPa/ WPp 0.96±0.029).

Elytra markedly convex, slightly depressed along suture, of normal length for genus (LE/ABL 0.59±0.022), with traces of 1–2 interneurs. Humeri ( Fig. 3 View FIGURES 3 – 6 ) moderately prominent, in outline nearly at right angle with longitudinal axis of body, dorsally moderately rounded, gradually enlarged to middle. Margins subparallel, slightly divergent in basal half, evenly rounded to apex, maximal width of elytra behind midpoint, approximately at 0.55–0.60 length. Elytra without subapical sinuation. Vestiture of elytra short (less than onefourth length of discal setae).

Prothoracic leg of males with strongly dilated tarsomere 1 (as in Fig. 7 View FIGURES 7 – 10 ) and strongly swollen (as in Fig.11 View FIGURES 11 – 14 ) profemur. Metafemora unmodified.

Median lobe ( Fig. 15 View FIGURES 15 – 18 a) evenly arcuate, with strongly enlarged, rounded apex and enlarged ventral margin with numerous poriferous canals. Canals absent on walls of median lobe itself. Dorsal copulatory sclerites semicircular, forming one large and one small curve. Base of copulatory sclerites slightly angulate, lacking distinctive sclerotized prolongations. Ventral sclerite and the spines of internal sac absent.

Left paramere ( Fig. 15 View FIGURES 15 – 18 b) slightly enlarged with four setae, apical longest. Right paramere ( Fig. 15 View FIGURES 15 – 18 c) markedly enlarged and robust, with four equal setae.

Spermatheca ( Fig. 19 View FIGURES 19 – 22 ) weakly sclerotized, shaped like a question mark, represented mostly by long and well-developed cornu with apical one-half sinuate. Distal part of cornu comparatively long, more than 1.5 times longer than its width. Ramus reduced and undifferentiated, nodulus short. Spermathecal duct more or less straight, without obvious coils.

Stylomers and sternum IX as in Fig. 23 View FIGURES 23 – 26 .

Distribution. Known from central and north-eastern parts of the Blount County, Tennessee, and adjacent parts of Swain County, North Carolina, within GSMNP.

Habitat. Beetles were collected in litter of different types of forests: xeric oak-pine, mesic oak, cove, and northern hardwood forests from low to middle elevations of the Smoky Mountains (500–1500m).

Differential diagnosis. Anillinus cieglerae is a member of a group of ovoid species with extensively developed microsculpture on foreparts of the body. It is the largest species of the langdoni – group. It is similar to A. langdoni in general outline, but the pronotum is proportionately less transverse. In comparison with A. pusillus the species has more oval elytra with maximal width further apically. Also, the proportion of the pronotum is different. The pronotum of Anillinus cieglerae appears more massive in comparison with the head. But these features are subtle, and more reliable identifications can be made by examination of males.

Males of A. cieglerae can be distinguished from all other langdoni – group species by the following combination of characters: strongly swollen profemora, form of tarsomere 1 of protarsi, short left paramere, form of the median lobe and form of copulatory pieces. Females of the species externally are practically indistinguishable from the other species, though examination of the spermatheca may help to separate the species from others.

Anillinus cieglerae occurs sympatrically with at least five species of Anillinus from different species groups and one species of Serranillus . In addition to the characters mentioned above to separate this species from other members of the langdoni -group, it can be distinguished from other Anillinus and Serranillus by the totally microsculptured foreparts of the body and by the smaller size.
