Anillinus longiceps Jeannel View in CoL

(Map fig. 40)

Anillinus longiceps Jeannel, 1963 b:149 View in CoL . Holotype male glued on rectangular card and labeled /‘red rectangular card’/Monteagle Tenn., 17 March 1931, Crystal Cave, Col. J.M.Valentine/ Anillinus fortis Horn View in CoL ? Barber det./ TYPE/ TYPE No 69547 USNM/ Anillinus longiceps View in CoL type R.Jeannel det., 19 /. Deposited USNM.

Holotype examined. Specimen is damaged, without head or contents of abdomen

(dissected but without genitalia), other parts of body in good condition.

Description. Large-sized for genus (sum of LP and LE, 1.91 mm). Color of body brunneorufous, appendages testaceous. Pronotum with distinct microsculpture across disc.

Pronotum moderately convex, transverse (WPm/LP, 1.28), with margins slightly constricted posteriad (WPm/WPp, 1.21) and slightly sinuate before posterior angles. Anterior angles evident, slightly prominent. Posterior angles nearly rectangular. Width between posterior angles slightly greater than between anterior angles (WPa/WPp, 0.94). Crenulation at posterior angles less developed then in other species of the genus with denticles at each margin with rounded tips.

Elytra oval, apical one-third convergent toward apex, moderately convex, moderately depressed along the suture, relatively long (WE/LE, 0.61), with traces of at least 5 interneurs. Humeri prominent, slightly rounded. Vestiture of elytra short.

Male metafemora apparently simple, but basal one-half concealed by mounting glue.

Genitalia not examined (missing).

Distribution. Known only from the type locality in Marion County, Tennessee ( Fig. 40).

Habitat. A true troglobite according to the label.

Differential Diagnosis. Anillinus longiceps is a troglobitic species with distinct microsculpture on the forebody, judging from the pronotum. The obtuse serrulations at the base of the lateral margins of the pronotum are unique. Additional specimens and aedeagal examination are required for further diagnosis, but its large size sets it apart from most species. Presumably, the species is restricted to a single cave system, making it unlikely to be confused with other endogean species.
