“…The close relationship of Telotylenchus with Tylenchorhynchus was pointed out by Siddiqi (1960). Telotylenchus shares most morphological characters with Tylenchorhynchus and differs from this genus only in having the dorsal pharyngeal gland extending over the intestine and in having a different en face view and structure of the gubernaculum (Siddiqi, 2000).…”

Stunt nematodes are characterized by phenotypic plasticity, with overlapping morphology and morphometry leading to potential misidentification. Consequently, the application of integrative taxonomic approaches is useful to species delimitation based on a combination of different perspectives, e.g. morphology and DNA sequences. We conducted nematode surveys in cultivated and natural environments in Spain and the USA, from which we identified 18 known species of the family Telotylenchidae and two new taxa within the studied samples. These species were morphologically, morphometrically, and molecularly characterized. The results of light and scanning electron microscopic observations, and molecular and phylogenetic analysis also allowed two new species to be distinguished, described herein as Bitylenchus hispaniensis sp. nov. and Tylenchorhynchus mediterraneus sp. nov. The phylogenetic analysis was carried out using molecular data from nuclear ribosomal DNA genes [D2–D3 expansion segments of the large ribosomal subunit (28S), internal transcribed spacer (ITS), and partial small ribosomal subunit (18S)]. We also provide here a test of alternative hypotheses that confirms the monophyly of both Tylenchorhynchus and Bitylenchus sensu Siddiqi's classification but does not support Fortuner & Luc's conceptual view of Tylenchorhynchus as a large genus. Ancestral state reconstructions of several diagnostic morphological characters using a maximum parsimony approach showed congruence in morphological and molecular evolution for stylet knob inclination and tail tip annulation. Our analysis emphasizes some of the problems related to the taxonomy and phylogeny of nematodes of Telotylenchinae. © 2014 The Linnean Society of London

“…Stunt nematodes are among the most investigated plantparasitic nematode groups. There are several classifications for different genera using various morphological characters and authors' views (Allen, 1955;Siddiqi, 1960Siddiqi, , 1979Siddiqi, , 2000Ryss, 1993;Decraemer and Hunt, 2006). Results based on sequences of the 28S rDNA also showed that genera such as Amplimerlinius, Merlinius, Geocenamus, Hexadorus (subsequently synonymized with Geocenamus), Nagelus, and Scutylenchus were included with Pratylenchoides in Merliniidae (Subbotin et al, 2006).…”

“…The family Dolichodoridae Chitwood in Chitwood & Chitwood, 1950 includes eight subfamilies, 24 genera and over 400 species worldwide (Decraemer & Hunt, 2006;Geraert, 2011;Sturhan, 2012). So far, several species of the genera Amplimerlinius Siddiqi, 1976, Geocenamus Thorne & Malek, 1968, Merlinius Siddiqi, 1970, Nagelus Thorne & Malek, 1968, Paramerlinius Sturhan, 2012and Scutylenchus Jairajpuri, 1971 of the subfamily Merliniinae Siddiqi, 1971, Neodolichorhynchus Jairajpuri & Hunt, 1984, Paratrophurus Arias, 1970, Quinisulcius Siddiqi, 1971, Trichotylenchus Whitehead, 1960, Trophurus Loof, 1956and Tylenchorhynchus Cobb, 1913 of the subfamily Telotylenchinae Siddiqi, 1960, andPratylenchoides Winslow, 1958 of the subfamily Pratylenchoidinae Sturhan, 2012 have been reported from Iran.…”

The list of plant parasitic nematodes of the family Dolichodoridae, known from Iran, is updated. 81 species belonging to 13 genera and three subfamilies are included in the list. Data for 29 species are added, of which seven species viz. Neodolichorhynchus phaseoli, Pratylenchoides crenicauda, P. erzurumensis, P. utahensis, Scutylenchus paniculoides, Trophurus impar and Tylenchorhynchus variannus are new records for the Iranian nematofauna. The list of species, further information on their morphometrics, references, referring to full or partial descriptions, associated plants, geographical distribution and some taxonomic remarks are provided. More detailed studies on some doubtful populations are proposed. The information on the taxonomic position of species in different classification schemes, as well as, the tendency of the species to certain climatic condition or ecological niche are provided. Challenges on the reliable identification of this group of nematodes in Iran are discussed and finally, suggestions were proposed for future studies.
