Family Staphylinidae

            Subfamily Oxyporinae

 Oxyporus (s. str.) kiteleyi Campbell

Description and Taxonomy

Length 7-9.5.6mm. The genus belongs to the monotypic subfamily Oxyporinae, a distinctive group of Staphylinidae that are easily recognizable by large, robust bodies, long, sickle-shaped prognathous mandibles, and extremely large, crescent-shaped terminal segments of the labial palpi (Campbell 1969).  The genus is almost worldwide in distribution and contains two subgenera, Oxyporus s. str. and Pseudoxyporus, with three and eight species, respectively, in eastern North America. The subgenus Oxyporus s. str. can be recognized by strongly compressed broad antennomeres with wide broad glabrous, shining medial areas (Campbell 1969). The species key was provided by Campbell (1979). This species and O. major can be distinguished from two other GSMNP species of the subgenus having black body and yellow markings on elytra (O. femoralis, and O. vittatus) by the black femora and tibia. Oxyporus kiteleyi and  O. major differ by the shape and color of the elytral vittae; diagonal and bright yellow in the former and longitudinal and ivory in the latter (Campbell 1978).

Life History

All Oxyporus species are mycophagous on various fleshy fungi, both as adult and larval stages. These fungi belong to three orders within the class Hymenomycetes: Agaricales (gilled mushrooms), Boletales (bolete mushrooms) and Polyporales (polypore mushrooms) (Hanley & Goodrich 1995). Females may construct and protect special chambers where the eggs hatch (Newton et al. 2000). This species is reported to feed on a few genera of fungi, primarily on Suillus spp. (Campbell 1978; Hanley & Goodrich 1995). The specimens from GSMNP were collected from unidentified fleshy fungi from late June to mid July at 980-1320 m elevation. 

Distribution

Poorly known since the species has been described relatively recently and still rare in collections (Campbell 1969). In addition to GSMNP localities, it has been reported from Quebec, Massachusetts and Georgia.

Conservation Concerns

Not under threat.
