The male of the species has a pale clay-yellow head, underside, and legs.[4] The back of its abdomen, pronotum disc, occiput (X), and a transverse bar in the middle of its face are a brownish-yellow.[4] Tegmina are fully developed, and are slightly wider than the pronotum.[4] It has long, thin cerci.[4] While the species is the smallest of the pale brown species of the genus Parcoblatta, its abdomen is modified like Parcoblatta lata, the largest of the genus.[4]
Fred A. Lawson wrote in 1967 that the female is fully winged and capable of flight, a trait he stated was unique among the Parcoblatta species in the United States,[5] while a 2003 study involving P. caudelli caught in North Carolina characterized the female as flightless.[6]

| Pronotum length | 2.9–3.4 mm (0.11–0.13 in) | 3.2–3.6 mm (0.13–0.14 in) |
| Pronotum width | 3.9–4.7 mm (0.15–0.19 in) | 4.1 mm (0.16 in) |
| Tegmina length | 11.8–16.0 mm (0.46–0.63 in) | 11.4–11.8 mm (0.45–0.46 in) |
| Tegmina width | 3.9–5.2 mm (0.15–0.20 in) | 3.8–4.0 mm (0.15–0.16 in) |
Distribution
editThe distribution of the species is the United States, in Arkansas, the District of Columbia, Indiana, Mississippi, North Carolina, Texas, and Virginia.[3] The species is considered adventive, but not established, in Ontario, Canada.[7]
Habitat
editThe species is common in forested areas,[6] and one researcher collected specimens from an old sawdust pile, at a former sawmill on the University of Tennessee Farm.[5]
