Cleptoria ‘n. sp. Hagoods’ Means and Marek 2017

Material examined: Type specimens. ♂ holotype ( VTEC MPE00291), 1 ♂ paratype ( VMNH SPC000389), and 2 ♀ paratypes ( VTEC SPC000390, 394). Holotype from South Carolina, Barnwell County, Toby Creek, near Hagoods Mill, SC-64 (33.2119°N, - 81.3201°W, Elev: 46 m), 23 November 2003, (Coll: D. Beamer). Paratypes from South Carolina, Barnwell County, Hagoods Mill, SC-64, 351 rd m W jct w/ Lebanon Rd., nr Toby Ck (33.21206°N, - 81.3198°W, Elev: 46 m), 17 October 2004, beneath leaf litter ( Quercus, Acer ) (Coll: P. Marek, D. Beamer, M. Beamer). Material examined listed in Supp Table 2 (online only).

Diagnosis: Adult males of Sigmoria beameri n. sp. are distinct from other apheloriine species based on the following combination of characters: Gonopods. Gonopodal acropodite broad, curving dorsomedially at an almost 90° angle at anterior bend ( Fig. 13A ). Basal zone lacking spines or tubercles, prefemoral process absent. Medial flange thick, laminate. Acropodite peak broad, flattened, distally with a wide, laminate lateral flange which is distinctly constricted at its base, setting it off from its ventrally-directed tip, separating it from other species with a birdhead-like acropodal apex (= Cleptoria ) Sigmoria abbotti (Hoffman, 1967) , Sigmoria bipraesidens (Hoffman, 1967) , Sigmoria macra (Chamberlin, 1939) , Sigmoria rileyi (Bollman, 1889) , Sigmoria robusta Shelley, 1986 , Sigmoria shelfordi (Loomis, 1944) , and Sigmoria arcuata (Shelley, 1981) . Acropodite without a cingulum, as in Brachoria and Appalachioria . Color. Tergites with light-red paranotal spots ( Fig. 5R ). Dark brown background. Collum with light red anterior and lateral margins.

Description: Supp Table 3 (online only). Based on Holotype (♂) MPE00291.

Measurements (mm): BL = 47.0, CW = 6.9, IW = 4.5, ISW = 1.5, B11W = 9.4, B11H = 5.8.

Variation: No significant variation from the holotype was observed.

Ecology: Sigmoria beameri n. sp. was collected from the riparian area around Toby Creek and was found under oak and maple leaves.

Distribution: Only known from the type locality, a small wooded area around Toby Creek, located in the Coastal Plain region of South Carolina.

Etymology: This species is named for its discoverer, Dr. David Beamer of Nash Community College. The specific name is a genitive noun derived as a patronym.
