Figure 4 in Tarantobelus Jeffdanielsi N. Sp. (Panagrolaimomorpha; Panagrolaimidae), A Nematode Parasite Of Tarantulas
Figure 4 shows the evolutionary relationships of 61 different nematodes as inferred from 18S rDNA sequences. Tarantobelus jeffdanielsi and T. arachnicida belong to the family Panagrolaimidae, Infraorder Panagrolaimomorpha (De Ley and Blaxter, 2002, 2004) with the closest relative being the vinegar eel, Turbatrix aceti AF202165.2. Furthermore, its position is corroborated by its placement in the 28S tree as a sister clade to (Medibullinae þ Tricephalobinae þ Panagrolaiminae þ Turbatricinae; Fig. 5) and confirming that it does not belong in the subfamily Brevibuccinae. Family Brevibuccidae Paramonov 1956 was considered a taxon of uncertain position (incertae sedis, De Ley and Blaxter, 2002). The 18S and 28S rDNA phylogenetic trees are not completely congruent, as the 28S rDNA tree shows Halicephalobus gingivalis and Panagrellus sp. as the closest relatives, whereas the 18S rDNA tree indicates that Turbatrix aceti is the closest relative.
