Diagnosis.

Adult males of Nannaria breweri sp. nov. are distinct from other Nannaria and the nearby N. scutellaria Causey, 1942, based on the following combination of characters: Gonopods. Acropodite curving medially throughout, not sinuous, only curving slightly medially as in N. tennesseensis and not straight, with 90° medial bend at apex as in N. scutellaria . Distal zone with large, lobed lateral flange (Fig. 52A, red arrow), not with small, triangular lateral flange as in N. tennesseensis, or medial flange as in N. scutellaria . Tip directed medially, not cephalically as in N. tennesseensis . Telopodite basal zone height <1/2 length of acropodite, not> 1/2 as in N. tennesseensis or ca. 1/4 length as in N. scutellaria . Prefemur with medially curving prefemoral process, not straight as in N. tennesseensis . Prefemoral tip bent dorsally (Fig. 52B). Prefemoral spine fused to prefemoral process throughout length, forming ridge along base of prefemoral process (Fig. 52C, red triangle). Color. Tergites with orange paranotal spots (Fig. 53). Brown background. Collum smooth with orange margin.

Measurements.

♂ holotype (VTEC, MPE02191): BL = 29.9, CW = 4.8, IW = 2.3, ISW = 0.9, B11W = 5.4, B11H = 3.6; ♀ paratype (VTEC, MPE02203): BL = 35.9, CW = 4.5, IW = 2.5, ISW = 1.0, B11W = 5.8, B11H = 4.4.

Variation.

No known variation.

Distribution.

Known from a linear area from southern West Virginia to northeastern Tennessee (Tennessee: Grainger and Hamblen counties; West Virginia: Mercer County; Virginia: Russell and Tazewell counties, Suppl. material 7; Fig. 126). Distribution area: 635 km2; status: MRE.

Ecology.

Individuals of N. breweri sp. nov. have been collected from mesic, broadleaved forests composed of pawpaw, maple, spicebush, oak, and elm, often under deciduous leaf litter and/or beneath 1-2 cm dark soil.

Etymology.

This species is named for its co-collector and West Virginian, Dr. Michael Brewer (Suppl. material 7). The specific name is a genitive noun derived as a patronym.
