Ceuthophilus guttulosus thomasi Hubbell, 1936 - A Camel Cricket


No image for this species.
Taxonomy
Family: Rhaphidophoridae Subfamily: Ceuthophilinae Tribe: CeuthophiliniSynonym: Ceuthophilus thomasi
Comments: One of 62 species in this genus that occur in North America north of Mexico (Cigliano et al., 2018); seven have been recorded in North Carolina
Species Status: Considered a full species prior to Eades' (1962) revision of this species group. Based on evidence that thomasi intergrades with guttulosus in areas of contact, Eades treated thomasi as a subspecies.

Comments: Most of the specimens of guttulosus obtained in the Mountains were determined by Eades (1962) to represent angulosus, including a number that Hubbell (1936) had previously considered to represent thomasi. The few remaining records for thomasi represent specimens apparently not reviewed by Eades and it is not clear if, in fact, thomasi actually occurs in North Carolina. None of the North Carolina specimens inspected by Eades (1964) were identified as thomasi, including several specimens collected in Haywood County. However, he does not mention having inspected any specimens from Watauga County. Given that the range of angulosus extends across the range of mountain counties in North Carolina, it seems unlikely that a second subspecies would be sympatric.
