Sudhausia floridensis n. sp. (Nematoda: Diplogastridae) isolated from Onthophagus tuberculifrons (Coleoptera: Scarabaeidae) from Florida, USA Academic Article uri icon

abstract

  • Sudhausia floridensis n. sp., a phoretic associate of a dung beetle, Onthophagus tuberculifrons, is described based on its typological characters and molecular profiles of part of the small subunit ribosomal RNA (rRNA) gene, D2-D3 expansion segments of the large subunit of rRNA gene, as well as part of the mitochondrial cytochrome oxidase subunit I (mtCOI) gene. Adult beetles collected from the cattle unit at the University of Florida, Gainesville, FL, USA were dissected and placed on a water agar plate to allow nematode propagation. The new species was isolated from a culture plate several weeks later, and subcultured to establish a laboratory strain. Sudhausia floridensis n. sp. is typologically very similar to S. aristotokia, but could be distinguished from it by the shape of the tail tip of the male, and presence vs absence of a terminal notch in the bursal velum. Molecularly, S. floridensis n. sp. is close to S. crassa, regardless of its morphological similarity to S. aristotokia, but it is distinguished from its African congeners S. aristotokia and S. crassa by 28 and 12 bp differences in SSU, respectively.
