aAbbreviations are defined in the study by Jairajpuri and Ahmad (1992).
bd = anterior to the guide ring/body width at the lip region (Brown et al., 1994).
cd’ = body width at the guide ring/body width at the lip region (Brown et al., 1994).

Phylogenetic relationships of Longidorus leptocephalus Hooper, 1961 within the genus Longidorus. Bayesian 50% majority rule consensus tree as inferred from D2 and D3 expansion domains of 28S rDNA sequence alignment under the general time-reversible model of sequence evolution with correction for invariable sites and a gamma-shaped distribution (GTR + I + G). Posterior probabilities more than 0.70 are given for appropriate clades. Newly obtained sequences in this study are shown in bold. Scale bar = expected changes per site. PP. posterior probabilities.
