Abolafia, Joaquín, 2023, A proposal to synonymize Loffienema with Haematozoon, Quercorhabditis with Diploscapteroides, and Stegorhabditis with Stomachorhabditis (Nematoda Rhabditida, Rhabditomorpha), including keys to species identification, Zootaxa 5258 (2), pp. 231-238 : 232-234

Quercorhabditis Shah, Hussain & Vaid, 2013

This taxon is characterized by having nematodes with lip region wider than the adjacent part of body, stoma with well develop, refringent and anteriorly curved cheilorhabdia, pharynx with swollen metacorpus and isthmus as long as procorpus, female reproductive system didelphic, female tail conoid or cupola-shaped, male tail leptoderan with reduced, anteriorly open, bursa having ten pairs of bursal papillae (genital papillae and phasmids, 3/4+2+ph). These morphological characters agree with those of the genus Diploscapteroides Rahm, 1928 .

The authors that proposed the creation of the genera Quercorhabditis compare their species with specimens of the genus Diploscapteroides and distinguished it from that in having "labial region set off by constriction and wider than adjoining body, heavily sclerotized cheilostom, absence of a ridge-like tooth in the gymnostom, spicules with a free dorsal arm, a somewhat boat-shaped gubernaculum and in having ten pairs of bursal papillae" characters appearing in species as D. coroniger Altherr, 1938 and D. dacchensis Timm, 1959 . According to this, Quercorhabditis is proposed as a junior synonym of Diploscapteroides .

The only species of Quercorhabditis , Q. rajouriensis Shah, Hussain & Vaid, 2013 , is similar to other species of the genus Diploscapteroides with widened lip region but distinguished from them by having longer female rectum and male with robust filiform part of tail. According to this, Q. rajouriensis is transferred to the genus Diploscapteroides as D. rajouriensis ( Shah, Hussain & Vaid, 2013) n. comb.
