03FB2778FF827A5FFF1DF9D4FBDD0FD8.taxon	description	Genus characterized by having tubular stoma with poorly developed valvular apparatus, pharynx with swollen metacorpus, female reproductive system didelphic-amphidelphic, female tail conoid-elongate, male tail leptoderan with anteriorly open bursa with reduced velum having spaced bursal papillae, appearing one genital papillae very anterior to bursa (1 + 3 / 2 + 2 + 2), and spicules with rounded manubrium, very narrow calamus and fusiform lamina. This morphology agrees perfectly with the members of the genus Haematozoon Leisering, 1865, which was restored by Sudhaus (2011), especially with H. subulatum (Leisering, 1865) Sudhaus, 2011 described by Osche (1952) as Rhabditis (Telorhabditis) inermiformis Osche, 1952, its junior synonym.	en	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.

03FB2778FF827A5FFF1DF9D4FBDD0FD8.taxon	description	The authors that propose the creation of the Loffienema genera did not compare their species with the members of the genus Haematozoon, which agrees perfectly, having identical stoma, spicules, bursa and genital papillae arrangement, its main diagnostic characters. These authors drawn spicules with heart-like manubrium but this character is no visible in the light microscopy pictures provided by them, being clearly rounded (Fig. 2 H in Shah et al., 2018), Thus, Loffienema is proposed as a junior synonym of Haematozoon. The only species described, L. dhanoriensis Shah, Allie, Vaid & Handoo, 2018, is very similar to Haematozoon subulatum Leisering, 1865 described as Rhabditis inermiformis by Osche (1952) and as Rhabditoides zocchi by Marinari-Palmisano (1967), both their junior synonyms. However, its body size is smaller (784 – 841 µm in females and 773 – 792 µm in males vs 1500 – 2000 µm in type females and 1200 – 1500 µm in type males of Haematozoon subulatum, 1196 – 2000 µm in females and 1265 - 1530 µm in males of R. inermiformis, and 937 – 1234 µm in females and 819 – 1089 µm in males of R. zochii), shorter and wider stomatal tube (3.6 longer than wide vs 6.6 times in R. inermiformis and 8.5 times in R. zochii, unfortunately, this character was not illustrated in detail in the type population), and shorter spicules (46 – 47 µm vs 60 – 69 µm in R. inermiformis and 55 – 61 µm in R. zochii). On the other hand, with respect to the second species of the genus, Haematozoon giardi (Maupas, 1915) Sudhaus, 2011, L. dhanoriensis also maintains smaller morphometry (1344 – 2030 µm in females, 1000 – 1573 µm in males, stomatal tube 8.8 times longer than wide, and spicules 52 – 57 µm). Although, L. dhanoriensis could be synonymized with some of these species, its smaller size makes it slightly different. Thus, the species is transferred to the genus Haematozoon as H. dhanoriense (Shah, Allie, Vaid & Handoo, 2018) n. comb.	en	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.

03FB2778FF837A5DFF1DF98FFC280C34.taxon	description	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. * Measurement from drawings. ** Measurements from other measurements. Unknown measurement. – Character absent. 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.

03FB2778FF877A5BFF1DFF3EFBE00E8C.taxon	diagnosis	This genus is characterized by having lip region very narrow, amphids very posterior, stoma tubular, long, having long denticles at metastegostom, pharynx with swollen, ovoid metacorpus, female reproductive system didelphicamphidelphic, tail in both sexes filiform, bursa absent and spicules with rounded and ventrally bent manubrium. This morphology agrees with the species of the genus Stomachorhabditis Andrássy, 1970 with which it is indistinguishable.	en	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.

03FB2778FF877A5BFF1DFF3EFBE00E8C.taxon	discussion	The authors that proposed the creation of the genus Stegorhabditis distinguished the specimens of this genus in having " six lips, evenly cuticularized stoma, presence of glottoid apparatus, a pair of setose denticles on each plate of stegostom, absence of stomach like folding in intestine, and in shape of spicules and gubernaculum ". However, these characters appear in the species of the genus Stomachorhabdis. Thus, e. g., the presence of six lips and the absence of stomach-like folding appear clearly in S. fastidiosa described by Massey (1971), setose denticles (incorrectly described as " a pair on each plate " because only one denticle is visible on each valve of the glottoid apparatus) are present at the stoma of all species of the genus, while the morphology of spicules and gubernaculum are identical in S. vietnamicus described by Andrássy (1970) and S. neotropica described by Andrássy (2001). On the other hand, the presence of a glottoid apparatus in S. abursata was wrongly drawn being this structure clearly absent in the light microscopy pictures provided by the authors. According to this, Stegorhabditis is proposed as a junior synonym of Stomachorhabditis. The only species described in Stegorhabditis, S. abursata Shah, Hussain, Vaid & Ahmad, 2015 a, is very similar to other species belong to the genus Stomachorhabditis, distinguished from them by having lip region poorly differentiated from the adjacent part of body.
