Size measurements (mm). -

Holotype: PrnL: 5.9, PrnW: 4.45, TegL: 27.8, TegW: 10.0, HwEx: 3.9, FemL: 27.2, TibL: 28.8mm (Fig. 17). Allotype: PrnL: 7.0, PrnW: 46, TegL: 28.0, TegW: 9.6, HwEx: 2.2, FemL: 29.9, TibL: 31.0, OviL: 11.0mm.

Etymology. -

This species is named for its geographic location, with populations north of the Pee Dee River, which isolates it from populations of A. carolina .

Common name. -

Pee Dee round-winged katydid.

Differential diagnosis. -

Amblycorypha peedee is best distinguished from other species in the Amblycorypha rotundifolia complex by calling song. Syllables are almost always produced in doublets with syllable rates within doublets of about 11.6s-1 at 25°C (Fig. 8) and rates of 4.0s-1 at 25°C between doublets. The sustained portion of calling songs of A. peedee has about 17 syllables with 2-3 syllables in each of the series preceding the sustained portion (Fig. 7).

Description. -

Individuals are typically green with characteristics of the Amblycorypha rotundifolia complex of Amblycorypha (Walker et al. 2003). The male’s calling song consists of a single syllable type that are produced in several (4-12) bouts of a 2-3 syllables preceding a sustained series of about 17 syllables (Figs 5, 7) that occur in pairs (doublets) (Fig. 5D). During the sustained portion of the song, at 25°C the syllable rate between doublets is about 4.0s-1 and is about 11.6s-1 within the doublet. The function of syllable rate within a doublet in response to changes in temperature is rate=0.583(temp)-2.92 (Fig. 8). Female size measurements for the single individual that was collected are PrnL: 7.05; PrnW: 4.58; TegL: 28.0; TegW: 9.63; FemL: 29.9; TibL: 31.0; OviL: 11.0. Males’ measurements (x -̄ ± SE in mm, N) are on average PrnL: 5.84 ± 0.04, 9; PrnW: 4.32 ± 0.06, 9; TegL: 28.2 ± 0.21, 9; TegW: 9.32 ± 0.18, 9; FemL: 27.3 ± 0.38, 6; TibL: 28.7 ± 0.44, 6 (Table 2).
