Subfamily:
Phaneropterinae
Tribe:
Amblycoryphini
Synonym:
Amblycorypha bartrami
Comments:
One of seventeen species in this genus that occur in North America (Cigliano et al., accessed 2024-09-25; Forrest et al., 2023). Seven species have been recorded in North Carolina.
Species Status:
Belongs to the Rotundifolia Species Group described by Walker et al. (2003), also Group II of Rehn and Hebard (1914).

Comments:
Green, with only the stridulatory field of the males marked with brown. Species of this group are distinguished by the songs of the males.
Structural Features:
Members of the Rotundifolia Species Group are characterized by the shallow humeral sinus of the pronotum; transverse metastermal lobes; and less strongly arcuate posterior margin of the pronotum.
Singing Behavior:
According to Forrest et al. (2023), syllables are almost always produced in doublets with syllable rates within doublets of about 11.6 per sec at 25°C and rates of 4.0 per sec between doublets at 25°C. 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.

Habitats and Life History
Habitats:
Xeric sandhills woodlands and scrub (Forrest et al., 2023).
Diet:
Observation Methods:

State Protection:
This species currently has no formal protection in North Carolina, although permits are needed to collect it on state parks or game lands.
Comments:
This recently described species is believed to be found only north of the Pee Dee River, with all records coming from North Carolina. It appears to be associated with xeric pine-oak scrub habitats, although one record comes from Anson County in the Piedmont, where the habitat is unknown. Only a few records currently exist.
