Additional material examined (n=2). U.S.A.: Tennessee: Blount Co.: Ψ, GSMNP, middle Prong Tr at 3944389 259358, 2200`, Berlese, 17 June 2006, C. Ware, C. Shapico, J. Hudson (LSAM); Sevier Co.: Ψ (slide mounted), GSMNP, Porters Creek N35°40.790’ W83°23.855’, SP2 Litter 3 of 3, 5 October 2006, M Gimmel (GSMNP).
Redescription of female. Length 2.6 – 2.8 mm. Head and pronotum blackish brown; elytra and abdomen brown, abdominal tergites III – V somewhat brighter; mouthparts, legs, and antennomeres 1 – 3, 11 yellowish brown (Fig. 1 c). Head somewhat glossy, pubescent, with microsculpture. Antennomeres 1 – 3 elongate, 4 longer than wide, 4 subquadrate, 6 – 7 subquadrate, and 8 – 10 transverse (Fig. 4 a). Carina on each side of ventral surface of head complete, attaining gular suture.
Mouthparts. Labrum transverse, bearing 3 pairs of short setae, and 7 pairs of long setae, a-seta, b-seta, and many pores (Fig. 4 b). Labium with two distal setae in a longitudinal row, and several pores in median area; a pair of setal pores, 2 pairs of real pores and several pseudopores present in lateral area (Fig. 4 c). Labial palpi bearing 12 setae (a – h, α – δ), γ-seta close to f-seta (Fig. 4 d). Mentum trapezoidal, bearing 4 pairs of main setae (b, u, v, w), a pair of additional setae, and many pores (Fig. 4 e).
Thorax. Pronotum wider than head, and approximately 1.23 times wider than long; somewhat glossy, with microsculpture. Mesoventrite with distinct reticulate microsculpture. Metaventrite with setigerous punctures. Elytra as wide as pronotum, approximately 1.55 times longer than wide, and approximately 1.2 times longer than pronotum; latero-posterior margin emarginate, somewhat glossy, and pubescent; setigerous punctures present. Hind wings present.
Abdomen. Abdomen glossy, wider than elytra, widest at abdominal tergites V – VI. Female abdominal tergites VI approximately 1.62 times wider than long; tergite VIII with posterior margin shallowly emarginate, bearing 4 pairs of main setae, and many additional short setae and pores (Fig. 4 f). Female abdominal sternite VIII bearing 5 pairs of main setae, and many additional short setae and pores (Fig. 4 g).
Genitalia. Spermatheca as in Fig. 4 h.
Male. Unknown.
Type locality. North Carolina (GSMNP).
Distribution. USA: North Carolina, Tennessee. Locations where L. (A.) smokyiensis has been collected in GSMNP as in Map 1.
Habitat. Both specimens examined were collected from forest habitat by sifting leaf litter in mid to late summer.
Comments. Pace (1989) mentioned that this species does not have hind wings, but our specimens have fully developed hind wings. We presume that the hind wings of the holotype may be damaged because wingless Leptusa species usually have short and compact elytra, such as L. (D.) gimmeli, described below.
