Diagnosis
Diagnosis.Leptusa (Dysleptusa) gimmeli differs from L. (D.) carolinensis by its smaller body length, shape of the spermatheca (Fig. 7 l), short elytra (apparently as long as wide, Fig. 1 f), and absence of hind wings. This species differs from L. (D.) smetanaiella by its shorter body length, color, subquadrate antennomere 4 (Fig. 7 a), and short elytra (apparently as long as wide, Fig. 1 f). Leptusa (D.) gimmeli has a median lobe shaped similar to that of L. (D.) carolinensis and L. (D.) smetanaiella, but it can be distinguished from those species by the shape of the bulbus: the anterior parts of the median lobe (Fig. 7 k).
Description
Description. Length 1.9 – 2.3 mm. Body brown, glossy; head and abdominal tergites V – VI blackish brown; antennomeres 1– 3, 11, mouthparts, legs, and abdominal tergite VIII yellowish brown (Fig. 1 f). Head pubescent and with microsculpture. Antennomeres 1 – 3 elongate, 4 subquadrate, 5 – 10 transverse (Fig. 7 a). Carina on each side of ventral surface of head incomplete, fading before attaining gular suture. Mouthparts. Labrum transverse, bearing 3 pairs of short setae, and 7 pairs of long setae, a-seta, b-seta, and pores (Fig. 7 b). Labium bearing two distal setae in a longitudinal row in median area; a pair of setal pores, 2 pairs of real pores and several pseudopores present in lateral area (Fig. 7 c). Labial palpi bearing 12 setae (a – h, α – δ) (Fig. 7 d). Mentum trapezoidal, bearing 4 pairs of main setae (b, u, v, w) and many pores (Fig. 7 e). Thorax. Pronotum wider than head, approximately 1.44 times wider than long, pubescent and with microsculpture. Mesoventrite with distinct reticulate microsculpture. Elytra as wide as pronotum, approximately 1.2 times longer than wide, approximately 1.06 times longer than pronotum, latero-posterior margin emarginate, and setigerous punctures present. Hind wings absent. Abdomen. Abdomen wider than elytra, widest at abdominal tergites V – VI. Abdominal tergite VI approximately 1.88 times wider than long. Male abdominal tergites VII – VIII with single median elongate tubercle (Fig. 7 f); tergite VIII bearing 4 pairs of main setae, and many additional short setae and pores; posterior margin with several tubercles, and shallowly emarginate (Fig. 7 f). Male abdominal sternite VII with many pores in anterior one-third; sternite VIII with posterior margin weakly produced, bearing 7 pairs of main setae, and many additional short setae and pores (Fig. 7 g). Female abdominal tergite VIII with posterior margin shallowly emarginate, bearing 4 pairs of main setae, and many additional short setae and pores (Fig. 7 h). Female abdominal sternite VIII with posterior margin rounded, bearing 6 pairs of main setae, and many additional short setae and pores (Fig. 7 i).

Distribution.USA: Tennessee. Locations where L. (D.) gimmeli has been collected in GSMNP as in Map 1.
Etymology
Etymology. This species is named in honor of Matthew L. Gimmel (Louisiana State University, Baton Rouge), collector of all but one specimen in the type series. Habitat. This species is known only from Albright Grove, an area of old growth forest in GSMNP and is represented by more specimens than any other species in the park. Over 100 specimens were collected from sifted leaf litter from both the spring and fall. Despite an extensive survey only a single specimen was collected from CWD in Albright Grove (emergent from decay class II).
