Adult males of N. fowleri are distinct from other Nannaria and the sympatric N. shenandoa , based on the following combination of characters: Gonopods. Gonopodal acropodite gradually curving medially before apex, not straight as in N. shenandoa . Distal zone short, bent medially forming 130° angle with acropodite (Fig. 15 View Figure 15 ). Telopodite with basal zone > 1/4 length of prefemoral process. Tip and distal zone simple, rectangular, blunt, < 1/8 length of acropodite, not large, curving with flange as in N. shenandoa . Prefemoral process arising from base of prefemoral spine, paralleling medial curve of acropodite (Fig. 15A View Figure 15 ), not directed laterally and crossing acropodite when viewed medially as in N. shenandoa or arising from top of prefemoral spine as in N. tasskelsoae sp. nov. Prefemur with stout, tooth-like prefemoral spine (Fig. 15C View Figure 15 , red triangle). Color. Tergites with orange paranotal spots (Fig. 16 View Figure 16 ). Dark brown background. Dorsum of collum smooth with orange margin. Chamberlin (1947) described the holotype as having yellow paranota, but his description was from a preserved specimen which had likely lost its color due to its preservation in alcohol.
♂ (VTEC, MPE03017): BL = 25.1, CW = 3.7, IW = 2.3, ISW = 0.8, B11W = 4.6, B11H = 2.9; ♀ (VTEC, MPE03098): BL = 28.8, CW = 3.7, IW = 2.3, ISW = 0.8, B11W = 4.4, B11H = 3.1.
A male taken from Cumberland, Maryland ( NCSM NAN0463), has a slight acropodite medial swelling, which has not been observed in other individuals of N. fowleri .
Nannaria fowleri has a larger distribution than most Nannaria minor species group Nannaria , perhaps due to post-glacial northward expansion from the eastern Appalachians (Virginia, West Virginia) north into Maryland, Pennsylvania and New York (Virginia: Bath and Highland counties; West Virginia: Pendleton and Pocahontas counties; Maryland: Allegany County; Pennsylvania: Centre, Clinton, Franklin, McKean, and Potter counties; New York: Cattaraugus and Monroe counties; Suppl. material 7; Fig. 127 View Figure 127 ). Distribution area: 43,054 km2; status: WRE.
Individuals of N. fowleri have been collected from mesic hardwood forests composed of maple, hemlock, and scattered pine, often buried 1-2 cm under dark, sandy soil.
Chamberlin (1947) gave no etymology for the name fowleri but it is reasonable to assume that the name refers to one of the collectors of the holotype, H. W. Fowler.
United States, Maryland, Garrett County, Jennings.
In the original description, Chamberlin (1947: 29) examined and designated the holotype male (ANSP Type no. 9951) collected in July 1907 by W. Stone and H. W. Fowler.
