Brachoria camptera Means, Hennen, Marek , New Species

Vernacular Name: ‘The City Lake Mimic Millipede’ Figs. 5L,M and 9 .

Material examined: Type specimens. ♂ holotype ( VTEC MPE01398), 6 ♂ paratypes ( VTEC MPE01323, 1325 , 1399 ; VMNH MPE01403, 1410 , 1416 ), and 2 ♀ paratypes ( VTEC MPE01405, 1413 ) from Tennessee, Putnam County, Cookeville, City Lake Natural Area , along trail out of parking lot (36.13143°N, - 85.4439°W, Elev. 303 m), 21 May 2016, ex beech, maple, deciduous woods, tuliptree, oak, umbrella magnolia, hickory, moist litter on hillsides, understory of poison ivy, honeysuckle, mayapple (Coll: J. C. Means, D. A. Hennen). Material examined listed in Suppl Table 2 (online only) .

Diagnosis: Adult males of Brachoria camptera n. sp. are distinct from other apheloriine species based on the following combination of characters: Gonopods. Gonopodal acropodite D-shaped ( Fig. 9A )—not circular as in Apheloria or oval as in Rudiloria species ( Fig. 12 ). Acropodite (when viewed posteriorly) narrow, onethird width of tibia on leg pair 9. Acropodite gradually tapered to acuminate apex, not with a blunt apex as in B. hubrichti . Acropodite distal to anterior bend slightly curved cephalically. Acropodite shaft with cingulum (midlength transverse groove). Prefemur with curved sickle-shaped prefemoral process ( Fig. 9B ). Color. Tergites black with 2 orange ( Fig. 5L ), or red ( Fig. 5M ), paranotal spots, not with purple/purple-gray metatergal stripes as in B. hubrichti and B. initialis .

Description: Supp Table 3 (online only). Based on Holotype (♂) MPE01398.

Measurements (mm): BL = 39.0, CW = 7.6, IW = 5.0, ISW = 1.5, B11W = 10.0, B11H = 5.2.

Variation: Individuals of Brachoria camptera n. sp. are known to exhibit two color morphs, 1) two-spotted red ( Fig. 5M ) and 2) two-spotted yellow-orange with a faint light blue caudal stripe ( Fig. 5L ).

Ecology: Individuals of Brachoria camptera n. sp. were collected in a mesic deciduous forest with dominant tree species of oak, maple, beech, and tuliptree.

Distribution: Known only from the type locality.

Etymology: This species is named for the shape of its acropodite, specifically the angular nature of its anterior bend. The specific name is a noun in apposition derived from the Greek kampter, ‘bend, angle’.
