Cartwrightia cartwrighti

Cartwrightia cartwrighti is a species of scarab found in South America. Oscar L. Cartwright named the species in 1967 after his brother. C. cartwrighti has been recorded in pastures and forests. It has also been found in cow dung.

Taxonomic history and etymology

The American entomologist Oscar L. Cartwright wrote the species description for C. cartwrighti in 1967. He placed it in the genus Cartwrightia which the Mexican entomologist Federico Islas Salas had named after him nine years earlier. Cartwright used three specimens to write his description: a male holotype and two female paratypes.[a] All three specimens were collected with a blacklight insect trap in early January 1960.[1]

Cartwright named this species after his brother Raymond Kenneth Cartwright. He was not an entomologist but accompanied Cartwright on several of his collecting expeditions.[1] Cartwright's colleague at the National Museum of Natural History Paul J. Spangler wrote Cartwright named this species "with tongue and cheek and the usual twinkle in his eye" and that this name led him to be "subjected to considerable kidding".[2] Elsie Herbold Froeschner's illustration of C. cartwrighti which accompanied Cartwright's original description was used as a logo for the invitation to Cartwright's retirement party; there he was gifted a set of stationery which was decorated with the same image.[2]


C. cartwrighti are found in tropical South America.[3] Its type locality, where the holotype and paratypes were collected, is the Saavedra Experiment Station, 60 mi (97 km) north of Santa Cruz de la Sierra in eastern Bolivia. This is at the edge of the Amazon basin near the Gran Chaco.[1]

C. cartwrighti has been subsequently found in the Bolivian town of San Ramón, Santa Cruz,[4] in Mata dos Godoy State Park (pt) in the state of Paraná in southern Brazil,[5] and in Presidencia de la Plaza, Chaco Province in northern Argentina.[6] The studies in Presidencia de la Plaza and San Ramón found C. cartwrighti only in forests but not in nearby pastures,[4][6] while the study in Paraná found specimens only in pastures but not in nearby forests.[5]


The male is 3.0 mm (0.12 in) long and 1.25 mm (0.049 in) wide; the female is 3.5 mm (0.14 in) long and 1.4 mm (0.055 in) wide. Its anterior pronotal ridges are narrow and sharply carinate. It has smooth black intervals on its elytra, but it otherwise has a grayish-brown clay-like covering, including on its underside.[1]


C. cartwrighti is a dung beetle and has been collected in cattle dung.[4]
