Appalachioria n. sp. ‘Foster Falls’ Means and Marek 2017

Material examined: Type specimens. ♂ holotype ( VTEC SPC000296), 1 ♂ paratype ( VMNH SPC000297), and 2 ♀ paratypes ( VTEC SPC000294, 295) from Virginia, Wythe County, N slope Fosters Falls Mountain, cove near road (36.89021°N, - 80.8376°W, Elev. 657 m), 29 May 2004, tulip, oak, maple, rhododendron, moist cove (Coll: P. E. Marek). Material examined listed in Supp Table 2 (online only).

Diagnosis: Adult males of Appalachioria sierwaldae n. sp. are distinct from other apheloriine species based on the following combination of characters: Gonopods. Gonopodal acropodite strongly curving ventromedially and with a strong distal cingulum, separating it from Apheloria and Rudiloria ( Fig. 7 ). Prefemoral process short and stout. Post-cingulum area expanded, wider than pre-cingulum area. Distal zone strongly curved medially into a long, uncinate, thin tip. Color. Tergites with yellow paranotal spots and yellow metatergal spots ( Fig. 5I ), but sometimes with orange metatergal spots ( Fig. 5H ). Black background. Collum with yellow lateral and anterior spots, sometimes with yellow or orange posterior spots, or lacking a posterior spot.

Description: Supp Table 3 (online only). Based on Holotype (♂) SPC000296.

Measurements (mm): BL = 40.0, CW = 7.0, IW = 4.7, ISW = 1.4, B11W = 9.4, B11H = 5.4.

Variation: No significant variation from the holotype was observed.

Ecology: Individuals of Appalachioria sierwaldae n. sp. were found in an Appalachian cove forest that included tulip, oak, maple, and rhododendron.

Distribution: Only known from the type locality on Fosters Falls Mountain in eastern Wythe County, Virginia.

Etymology: This species is named for Dr. Petra Sierwald of the Field Museum of Natural History. The specific name is a genitive noun derived as a matronym.
