Abstract
- Ektaphelenchoides caspiensis n. sp. is described and illustrated based on morphological, morphometric and molecular characters. The new species is characterised by its continuous lip region, obscure lateral field, females with body length of 499-572 µm, 9-10 µm long stylet, excretory pore posterior to base of metacorpus at 62-72 µm from anterior body end, short post-uterine sac ca 0.5 times corresponding body diam. or 4-9 µm long, and posterior body end (i.e., including 'tail') very long and filiform. Males are common and have 7-8 µm long spicules, five copulatory papillae and a long (109-140 µm) conoid tail with very long filiform terminus. Based on morphological and molecular characters, it comes close to five known species of the genus, namely: E. attenuata, E. fuchsi, E. kelardashtensis, E. musae and E. ruehmi. It differs from the closest species, E. kelardashtensis, by the shorter female stylet (9-10 vs 13-16 µm), more anterior vulva (V = 51.7-58.1 vs 61.5-68.0), more posterior excretory pore (62-72 vs 55-66 µm from anterior end), very long posterior body (i.e., including 'tail') in female, and male tail shape (conoid with very long filiform terminus vs conoid, sharply pointed). Comparisons with other close species of the genus are also discussed. Molecular analyses were performed using 732 bp of the partial ribosomal RNA large subunit gene (D2-D3 of LSU) using Bayesian inference (BI) and maximum likelihood (ML) methods and showed that the new species formed a clade with one species of the genus (E. fuchsi) and Devibursaphelenchus lini.
