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.
