Adult males of Nannaria tennesseensis   are distinct from other Nannaria   and the nearby species N. scutellaria   , based on the following combination of characters: Gonopods. Gonopodal acropodite sinuous, curving slightly medially, not curving medially as in N. breweri   sp. nov. and not straight with 90° medial bend at apex as in N. scutellaria   . Distal zone heavily reduced, with small triangular lateral flange (Fig. 59B View Figure 59 , red arrow)-without large lobed lateral flange as in N. breweri   sp. nov., or medial flange as in N. scutellaria   . Acropodite tip directed cephalically, not medially as in N. breweri   sp. nov. or N. scutellaria   . Telopodite basal zone long, > 1/2 length of acropodite, not < 1/2 as in N. breweri   sp. nov. or ca. 1/4 length as in N. scutellaria   . Prefemur with straight prefemoral process, not medially curving as in N. breweri   sp. nov. Prefemoral spine fused to prefemoral process throughout length (Fig. 59A View Figure 59 , red triangle). Color. Tergites with sherbet orange paranotal spots (Fig. 60 View Figure 60 ). Brown background. Dorsum of collum smooth with orange and white caudal margin.


♂ (VTEC, MPE01245): BL = 29.2, CW = 3.2, IW = 1.8, ISW = 0.7, B11W = 4.2, B11H = 2.5; ♀ (VTEC, MPE01291): BL = 34.8, CW = 3.9. IW = 2.5, ISW = 1.2, B11W = 4.7. B11H = 3.5.


No known variation.


Known from eastern Tennessee in the vicinities of Jefferson City and the Great Smoky Mountains National Park (Tennessee: Blount, Jefferson, and Sevier counties; Suppl. material 7; Fig. 126 View Figure 126 ). Distribution area: 1,440 km2; status: SRE.


Individuals of N. tennesseensis   have been collected from a variety of habitats, including mesic mixed hemlock and hardwood forests primarily composed of oak, maple, tuliptree, hemlock, and rhododendron, and semi-xeric hardwood forests composed of oak and maple. In the former habitats, specimens were often found under leaf litter and/or under 1-2 cm of dark, loose soil; in the latter habitats, specimens were found walking on top of hard packed soil, under thin oak leaf litter.


Bollman (1888) gave no etymology for the name tennesseensis, but it is reasonable to assume that the specific name refers to the state in which it is found.

Type locality.

United States, Tennessee, Jefferson County, Mossy Creek.


In the original publication Bollman (1888: 340) inspected two lots of specimens, Nos. 203 & 388. No. 203 contained just one specimen, a female syntype, while No. 388 consisted of five specimens, two males and three females. Bollman (1888: 340) notes that he deposited two of the lot No. 388 specimens at the USNM (now NMNH) though he does not mention the sex of these specimens. Bollman (1888: 340) mentioned two “types”, one from each of the lots. The type from lot No. 388 was deposited in Bollman’s private collection, and its current whereabouts are unknown. Both lots were collected by C. Branner on unspecified dates.
