Buetschlinema Sudhaus, 2011

syn. nov. Chylorhabditis Kanzaki, Hamaguchi & Takeuchi-Kaneko, 2021 :

C. epuraeae Kanzaki, Hamaguchi & Takeuchi-Kaneko, 2021

It is obvious that C. epuraeae belongs to the same clade as Buetschlinema ( Kanzaki et al. 2021a) , The main difference is the pattern of genital papillae that point to the dorsal side of the bursa velum. This can change by shift of the anlagen of these papillae ( Sudhaus & Fitch 2001). Even if C. epuraeae could be shown (which is not the case) to be the first branch and thus sister taxon to a group with all the other Buetschlinema species, this would not be a good argument to erect a new genus taxon in this place.

Type species: Rhabditis buetschlii de Man, 1876

Five valid species were listed in the catalogue 2011. Here a new one is added.

• B. epuraeae ( Kanzaki, Hamaguchi & Takeuchi-Kaneko, 2021) comb. n. – Uji River, Yawata, Kyoto, Japan; from the beetle Epuraea (Haptoncus) ocularis from sap on the trunk of a Chinese elm ( Ulmus parvifolia ). – Special characters: arrangement of GPs 4 adcloacal and 1+1+3 postcloacal, GP5 and GP8 to the dorsal surface of bursal velum, spicules long and separated into two sections of equal length by a constriction.
