There are no additional previously reported localities. Diagnosis. Medium to large typical members of the valentinei group (ABL = 1.63–1.98 mm), with distinctive male and female genitalia, described below. Redescription of male genitalia. The median lobe (Figs 30 K, 31 A – O) has a narrow ventral margin and a small, rounded apex. In some individuals, there are several short setae present on the ventral margin. The flagellum is large and heavily sclerotized, rotated dorsally so that in right lateral aspect it is viewed through its base, falsely appearing to be evenly curved basally and straight beyond sinuation (Figs 30 K, 31 A, D, G, J, M). In dorsolateral aspect, the flagellum appears as illustrated in Sokolov et al. (2004), with a large basal piece and a long bisinuate shape that slightly surpasses the ostium (Fig. 31 E, H, K, N). Several small blunt sclerites are present in the internal sac, as well as a small field of acute spines. Right paramere small and narrow, with four long apical setae that vary in their placement (Fig. 30 L, M). The left paramere is narrowly conchoid and asetose (Fig. 30 J). Description of female genitalia. Spermatheca long, deeply bisinuate, gradually enlarged distally (Fig. 21 D). Spermathecal duct apparently absent. Bursa without sclerotization. Variation noted. In specimens from the vicinity of Sassafras Mountain in northern Pickens Co, SC, the flagellum of the internal sac of the aedeagus has a longer and broader basal curve and shorter apical curve (Fig. 31 D – F). In specimens from southern localities in Pickens Co., SC, the internal sac of the median lobe lacks the blunt teeth present in other populations, the apical sclerite is saddle-shaped and lacks sharp projections, and the flagellum appears quite different from other populations in right lateral aspect (Fig. 31 M) and dorsal aspect (Fig. 31 N), because it is rotated differently within the median lobe in repose. Similarly, the spermatheca is the same size, but is oriented in a C-shape rather than an S. Further studies might support splitting A. murrayae into two or more species, but our sampling is too limited to support such an action. Distribution. This species is widely distributed, from Macon Co., NC east to Henderson Co., NC, north to the type locality in GSMNP and Round Knob in Buncombe Co. (Fig. 29). The population at the South Carolina Botanical Garden is the southernmost known locality. Sympatry. Specimens of A. murrayae have been collected in association with A. mica and A. micamicus at Waldrop Stone Falls, SC; with A. merritti at Indian Camp Creek, SC; with A. cherokee and A. sp. “ South Carolina, Coon Branch ” at Coon Branch, SC; with A. merritti and A. langdoni - group sp. near Wayah Bald, NC; and the paratype series from Jackson Co., NC is a mixture of A. murrayae and A. loweae (see Notes below). Serranillus dunavani co-occurs with A. murrayae at most of the known localities. Natural history. A mating pair was observed on the underside of a rock on 14 March 2020 at Ashmore Heritage Preserve in Greenville Co., SC. Specimens have been collected from sifted leaf litter, under embedded rocks, and using modified buried pitfall traps. Notes. Three of the male paratypes of A. murrayae in the NCSU collection are actually members of A. loweae, and have been labeled as such.
