Rudiloria ‘n. sp. Chagrin’ Means and Marek 2017

Material examined: ♂ holotype ( VTEC MTX 0185) from Ohio, Cuyahoga County, Cleveland Metroparks, South Chagrin Reservation, Henry Church Rock Loop Trail, near falls and swimming hole (41.41598°N, - 81.4145°W), 12 June 2010, ex on top dead leaves in maple forest (Coll: P. E. Marek). Material examined listed in Supp Table 2 [online only].

Diagnosis: Adult males of Rudiloria charityae n. sp. are distinct from other apheloriine species based on the following combination of characters: Gonopods. Gonopodal acropodite smoothly oval-shaped ( Fig. 12A )—not circular as in Apheloria species. Acropodite (when viewed posteriorly) narrow, onethird width of tibia on leg pair 9. Acropodite gradually tapered to acuminate apex–curved one-dimensionally to apex, not twisted cephalically as in Apheloria species. Acropodite shaft smooth without cingulum (midlength transverse groove) as in Brachoria ; without teeth, swellings, joints, or projections as in other Rudiloria species. Prefemur with a nubbin-like prefemoral process, one-tenth length of acropodite ( Fig. 12C ), not long and scythe-like as in Rudiloria kleinpeteri , Rudiloria trimaculata . Color. Tergites with 3 spots: 1 orange metatergal spot, 2 yellow paranotal spots ( Fig. 5Q ). Collum with yellow spot anteriorly, gradually fading into orange metatergal spot.

Description: Supp Table 3 (online only). Based on Holotype (♂) MTX0185.

Measurements (mm): BL = 34.0, CW = 6.1, IW = 4.1, ISW = 1.2, B11W = 7.2, B11H = 4.5.

Variation: No significant variation from the holotype was observed.

Ecology: Individuals of Rudiloria charityae n. sp. have been collected in deciduous broadleaved forests of maple and beech.

Distribution: Rudiloria charityae n. sp. is known from Cuyahoga and Geauga counties in the Erie Drift Plain Region, and Monroe County in the Western Allegheny Plateau Region of eastern Ohio.

Etymology: The holotype specimen was collected on the wedding day of PEM during a family hike to his childhood swimming hole in the Chagrin River, Cuyahoga County, Ohio. The species is named for his wife Charity Hall.
