New insights into the identity of Discolaimium dubium Das, Khan and Loof, 1969 (Dorylaimida) as derived from its morphological and molecular characterization, with the proposal of its transference to Aporcella Andrássy, 2002

. Molecular analyses of LSU rDNA sequences of three Iranian specimens of D. dubium sheds some light on the identity of this species. Their evolutionary relationships, as observed in the tree provided in Figure 4, reveal that these sequences form part of a highly supported (98%) large clade including several taxa, all of them having in common the absence of pars refringens vaginae, so confirming previous findings (Álvarez-Ortega and Peña-Santiago, 2016; Álvarez-Ortega et al., 2013; Imran et al., 2019

transferred to a small drop of TE buffer (10 mM Tris-Cl, 0.5 mM EDTA; pH 9.0, QIAGEN Inc., Valencia, CA) individually on separate clean slides, and each specimen was squashed using a clean slide cover glass. The suspension was collected by adding 50 μl TE buffer. Each sample was regarded as an independent DNA sample, and stored at −20°C until used as polymerase chain reaction (PCR) template. Primers used for the PCR amplification of the D2–D3 expansion domains of the LSU rDNA were forward D2A (5

stomatal opening formed from four flaps; greatly expanded labial disc; and eight-sectored annule-like column supporting the labial disc. Thirteen nematodes from various hosts were sequenced for 28S LSU rDNA and compared with other millipede-inhabiting nematodes. Stauratostoma shelleyi is the sister group to the few Thelastoma spp. that have been molecularly characterized using the D2–D3 expansion segments of the 28S LSU rDNA.

These results confirmed longitudinal amphidial aperture type on lateral sides of the lip region in genus Discotylenchus, as noted by Siddiqi while erecting the genus with D. discretus as the type species. Molecular phylogenetic analyses using partial small subunit (SSU) and large subunit (LSU) rDNA sequences revealed the affinity of the genus Discopersicus n. gen. with members of the subfamily Boleodorinae, as supported by morphological characters (mainly, the oblique

The following primers were used for amplification and sequencing: SSU F04 (GCTTGTCTCAAAGATTAAGCC) and SSU R26 (CATTCTTGGCAAATGCTTTCG) (Blaxter et al., 1998) for SSU rDNA; and D2A (5´-ACAAGTACCGTGAGGGAAAGTTG-3´) and D3B (5´-TCGGAAGGAACCAGCTACTA-3´) (Subbotin et al., 2006) for D2-D3 LSU rDNA. Four microliters of PCR products were loaded on a 1% agarose gel (40 mMTris, 40 mM boric acid, and 1 mM EDTA) to check the quality of the amplified DNA.
