1F530A59D979FFF0FC02FB77FE6AFB3A.taxon	description	Adult habitus. General color dark brown without distinctive head pattern. Wings brown, legs pale brown. General appearance typical of genus. Male. Forewing length 6 - 6.5 mm (N = 10). Epiproct sclerite mushroom shaped; median sclerite on tergum 9 large, covering most of field. Anterior margin of tergum 8 bearing a low, triangular lobe; posterior margin of lobe typically rounded (Figs. 1, 6). Outer lobes of paraprocts shorter than inner lobes, broad in basal third (Fig. 2), but narrowed in remainder and curved forward in apical third to form a blunt hook (Figs. 8 - 10). Inner paraproct lobes (specilla) somewhat cylindrical in anterior aspect (Fig. 1), widest basally and tapered to a bluntly rounded knob (ca. 38 µm wide) (Figs. 1, 7); from lateral aspect (Fig. 9) the inner lobes are straight along their dorsal (anterior) margins and smoothly curved along their ventral margins to a bluntly rounded apex. Outer subapical margins of inner paraproct lobes bear a cluster (3 - 6) of low rounded tubercles (ca. 4.5 - 6 µm long), and caudoventral margins bearing a series (2 - 5) of slightly smaller, additional tubercles beginning near the apex and continuing along caudoventral keel (Figs. 7 - 11). Vesicle on sternum 9 small and triangular (Fig. 2). Female. Forewing length 7 - 7.5 mm (N = 5). Subgenital plate projects over base of sternum 9 (Fig. 3). Posterior margin of plate bearing a median notch, slightly expanded mediolaterally; lobes truncate and conspicuously hairy. Spermathecal sclerite dark brown, semicircular in dorsal aspect with long, slender ventrolateral blade-like structures (Figs. 4 - 5). Larva. Pre-emergent body length 6 - 7 mm (N = 4). General color pale brown with obscure pattern on head; occiput with faint, irregularly elongate mottled areas and ocellar area often with a slightly darker median T-shaped line (Fig. 41). Pronotum bearing 4 - 6 mixed length setae at anterolateral corners and 1 - 2 finer setae at posterolateral corners (Fig. 41); mesonotum with a few short anterolateral setae, wingpads bare. Apical abdominal segments with posterolateral fringe row well developed and consisting of close-set, short thick setae (Fig. 42); intercalary setae short, thick and restricted to posterior half of each tergum, sterna typically bare except for a single long seta on sternum 9. Paraprocts with heavy fringe of short, thick marginal setae. Cerci with ca. 20 segments; posterior margins of basal segments with apical fringe composed of short setae which become progressively longer through ca. segment 14, longer setae more numerous laterally; setal fringe on apical cercal segments consisting of a few, often only one, seta (Figs. 43 - 44).	en	Harrison, Audrey B., Stark, Bill P.

1F530A59D979FFF0FC02FB77FE6AFB3A.taxon	diagnosis	Diagnosis. This species is a member of the L. ferruginea subgroup and is difficult to distinguish from L. ferruginea proper using dissecting microscopes, but the two species may be resolved with compound microscopy (400 X) or scanning electron microscopy. Because the lectotype (and two paralectotypes, Kimmins 1970) from Nova Scotia (British Museum of Natural History) of L. ferruginea are females designated by Ricker (1938), we sought male specimens of the L. ferruginea complex from Nova Scotia (the type locality) and other Canadian and New England localities to assist in resolving the identity of L. ferruginea (Walker 1852) and its synonym, L. decepta Claassen (1923) described from the Ithaca, New York area. R. W. Baumann, B. C. Kondratieff and J. I. Earle graciously provided specimens from Nova Scotia, Newfoundland, New York, New Jersey, Pennsylvania and Tennessee which we examined with SEM. Several images (Figs. 18 - 23), provided for comparison, indicate the paraprocts for L. ferruginea are similar in shape to those of L. colemanorum but the apical armature in the former species consists of 1 - 3 apicolateral, small spurs; typically these spurs are slightly longer and hooked laterad (as shown in Fig. 8 of Harper & Harper 2003) rather than consisting of low rounded tubercles of the type found in L. colemanorum. Nova Scotia specimens, presumed to be typical for the species, show 2 or 3 hooked apical spurs as in Figs. 18 - 19, and specimens from two New York localities (Figs. 21 - 22) are also similar in this respect. Some specimens from the northeast may also bear one or more caudoventral tubercles but the grouping, position and shape of the major spurs appears to be distinctive. Images are also provided for specimens of L. ferruginea found at Mississippi (Figs. 15 - 17) and Tennessee sites. These southern specimens, and those from Washington Parish, Louisiana, typically have only one major dorsoapical spur and often a smaller, distal spur or tubercle. The larva (Figs. 41 - 44) is identified as L. ferruginea using Harper & Hynes (1971) but in the few specimens available, the new species has almost no setae on the basolateral margins of the mesonotum whereas L. ferruginea is shown with a small setal cluster in this position by Harper & Hynes (1971). In addition, L. ferruginea has at least one seta shown in profile on several ventral abdominal segments and in L. colemanorum specimens these are absent, except for sternum 9. Larvae of the new species are also quite similar to those of L. szczytkoi, but that species also has several basolateral setae on the mesonotum and a single ventral seta on sterna 8 and 9 (DeWalt & Stark 1996).	en	Harrison, Audrey B., Stark, Bill P.

Collections of the new species are from seven different springs (8 total sites) in Yalobusha and Calhoun counties, Mississippi, all located on private property. These springs drain into tributaries of the Skuna River or the Yalobusha River above Grenada Reservoir. The Yalobusha and Skuna are tributaries of the Yazoo River system of northwestern Mississippi.

1F530A59D97FFFFDFEB8FB77FEA9FD4B.taxon	diagnosis	Diagnosis. This species is a member of the Leuctra rickeri subgroup of the L. ferruginea species complex which includes L. alabama, L. paleo, L. rickeri James and L. szczytkoi. Within this group only L. hicksi has broad inner paraproct lobes in caudal and anterior aspect which narrow abruptly in the apical third (Figs. 25, 32). Comparative images of the paraprocts and tergal lobes of specimens presumed to be L. alabama (Cold Spring, Madison Co., Alabama) and L. rickeri (Burden Creek, Pope Co., Illinois) are presented in Figs. 35 - 40. The paraprocts of these are virtually identical suggesting only one of these species is valid. Additional images are also provided for specimens of L. paleo from a site near the type locality in Columbia Co., Arkansas (Figs. 45 - 50), and for L. szczytkoi specimens collected at the type locality of Schoolhouse Springs, Jackson Parish, Louisiana (Figs. 51 - 56). These images indicate the latter two species are also very similar, and probably synonymous, but they are clearly distinct from L. hicksi and other populations of the L. rickeri subgroup known from east of the Mississippi River. The spines on the inner lobes of the paraprocts of L. szczytkoi and L. paleo (range 48 - 55 µm) are ca. 2.5 - 3 times as long as those on paraprocts of L. hicksi and other eastern members of the subgroup (range 18 - 22 µm). In addition, in lateral aspect the eastern species have the inner lobes much narrower basally and broader and more rounded near the tips, and in caudal aspect the western species have an eroded appearance below the apical orifice (Figs. 47 - 48, 54), whereas the caudal surfaces of the eastern species are relatively smooth (Figs. 37, 40).	en	Harrison, Audrey B., Stark, Bill P.

1F530A59D977FFF8FEA6FF68FE2BFBCD.taxon	discussion	Comments. Although the holotype is from Kentucky, most of the paratype series of this species are from sites in the Shawnee National Forest near the Burden Creek location of our specimens. The Logan Branch, Kentucky site is in a county adjacent to Menifee Co., where the holotype was collected. As discussed above for L. alabama, the holotype and topotype specimens need to be carefully studied to evaluate the status of this species. Additional material is needed to allow examination of Mississippi specimens with SEM.	en	Harrison, Audrey B., Stark, Bill P.
