Abstract
Data on five known species of the genus Coslenchus are provided. Morphological and morphometric data are given for all studied species. Three of the recovered species were also characterized by molecular phylogenetic data. The species C. leiocephalus was studied for the first time since its original description. Males of the species, C. franklinae and C. oligogyrus were described for the first time and the species C. oligogyrus was reported from Iran for the first time. In molecular phylogenetic studies based on partial sequences of 28S rDNA D2/D3 fragments, all species formed a clade with high Bayesian posterior probability in Bayesian inference, indicating the monophyly of the genus. The clade of Coslenchus spp. formed a highly supported monophyletic group, a sister clade to two species of the genus Aglenchus.
Highlights
Data on five known species of the genus Coslenchus are provided
The morphometric data and morphological characters of the recovered population of this species from Divan Dashi region are in full agreement with those given for the original population (Siddiqi, 1978), the Iranian population studied by Karegar and Geraert (1996) and the data given by Geraert (2008)
It is characterized by having cuticle with 14 longitudinal ridges and four incisures in lateral field, slightly offset head with three or four annuli, large vulval flaps, absence of postvulval uterine sac (PUS) and a filiform tail
Summary
Data on five known species of the genus Coslenchus are provided. Morphological and morphometric data are given for all studied species. Siddiqi (1978) erected the genus Coslenchus and transferred Tylenchus costatus de Man, 1921 to it as the type species. According to molecular phylogenetic studies on species of the genus using D2/D3 domain of 28S rRNA gene, the genus Coslenchus has close phylogenetic affinities with genus Aglenchus Andrassy, 1954 (Subbotin et al, 2006; Palomares-Rius et al, 2009; Atighi et al, 2012), a morphologically close genus. The present paper illustrates some Coslenchus spp. recovered from the region
