Buccal cone with 6 papular peribuccal lobes visible only under SEM and only when the buccal cone is fully extended (Fig. 3 A – D). When observed laterally, the buccal tube appears to have two bends: the first, more pronounced, at the beginning of the anterior portion of the buccal tube, in correspondence with the area bearing the ventral lamina; the second, less pronounced, approximately halfway along the tube (Fig. 4 A). A very short, protruding ventral strengthening lamina (similar to a large, well protruding crest) is present. The lamina has a modest notch approximately one-third along its length: the first third is nearly straight, with a smooth margin, the central portion (from 1 / 3 rd to 2 / 3 rd of the lamina length) has a convex, more thickened, and slightly serrated (more visible in bigger specimens) margin; the final portion of the posterior segment appears straight and smooth (see Fig. 4 A, D). Three macroplacoids (length sequence 2 &lt;3 &lt;1), with the first being very long and rod-shaped (more than twice the length of the second), showing a slight median incision; the second macroplacoid has granular shape; the third macroplacoid is elongated and nearly twice the length of the second (Fig. 4 E).</p><p>Pseudobiotus morphotype of the Isohypsibius - type claws (Gąsiorek et al. 2019 b), resembling those found in the genus Thulinius and Pseudobiotus, i. e., claws elongated, with a clear hump on the primary branch (Fig. 5) and with relatively elongated secondary branches br&gt; 70 % (Gąsiorek et al. 2019 b). Lunulae or pseudolunulae absent, but claw bases in all legs with internal septa clearly visible under LM (see Fig. 5 C), giving the impression of a “ duck’s foot ” shape; this particular structure showed to be more visible in specimens mounted in Hoyer’s than in specimens mounted in Polyvinyl Lactophenol, probably due to a stronger clearing effect of the former mounting medium.</p><p>Thulyphoribius gen. nov. differential diagnosis.</p><p>The new genus is morphologically and molecularly (Fig. 1) well separated from all other extant genera of Isohypsibioidea, and in particular it is distinct from known members of the family Doryphoribiidae, with which the new genus shares the most morphological characters (primary and secondary branches of claws of similar size and presence of a ventral lamina in the buccal apparatus in some genera; Gąsiorek et al. 2019 b).</p><p>Among Doryphoribiidae, based on the presence of a rigid buccal tube, three macroplacoids and no microplacoid in the pharynx and a cuticle devoid of dorsal gibbosities, Thulyphoribius gen. nov. can be compared to Doryphoribius Pilato, 1969 (species in the zappalai group sensu Michalczyk and Kaczmarek 2010), Thulinius Bertolani, 2003, Pseudobiotus (only some species have 3 + 0 placoids configuration) and Grevenius Gąsiorek, Stec, Morek &amp; Michalczyk, 2019 (belonging to asper group sensu Massa et al. 2024). Characters differentiating Thulyphoribius gen. nov. from the above-mentioned genera / groups are presented in Table 1.</p><p>In particular, Thulyphoribius gen. nov. can be considered particularly similar to Doryphoribius (for the presence of a ventral lamina in the buccal apparatus) and Thulinius (by the shape of the placoids, claw structure and shape and presence of cuticular bars on legs). Therefore, we compare it below with these two genera.</p><p>The new genus differs from Doryphoribius by: The ventral lamina which has a peculiar shape, being very short and thick (pt 35–45 in the new genus vs pt&gt; 50 in Doryphoribius, except for D. smokiensis which, however, possesses only two macroplacoids), resulting in a buccal tube morphology with a sharply curved proximal section (Figs 4 A, 6 B).</p><p>First and third macroplacoid have a bar-like shape, while the second has a granular shape, whereas in Doryphoribius (in species exhibiting three macroplacoids), all macroplacoids are granular (or almost granular) in shape.</p><p>Claws of the Pseudobiotus - type in the new genus according to Gąsiorek et al. (2019 b): “ with secondary and primary branches similar in height (br typically&gt; 70 %), elongated basal tracts, and typically prominent humps on primary branches of internal and anterior claws ”, while in Doryphoribius, claws are of Isohypsibius - type in (i. e. “ without the hump on the primary branch and with a considerable difference in primary and secondary branch height (br ≤ 70 %) ” according to (Gąsiorek et al. 2019 b)).</p><p>Claw bases provided with internal septa in the new genus while in Doryphoribius the septa in claw bases are absent.</p><p>A long cuticular bar under both internal and external bases of claws I – III is present, while cuticular bars on legs are absent in Doryphoribius .</p><p>The new genus differs from Thulinius by: The peribuccal cone surrounded externally to the buccal ring by 6 papular peribuccal lobes in the new genus, while ordinary peribuccal lobes are present in Thulinius .</p><p>Apophyses of the stylet muscle insertion (AISM) represented only by a single, large, ventral apophysis (i. e., the ventral lamina) in the new genus, whereas both ventral and dorsal crests are present, smaller and similar in shape, in Thulinius .</p><p>Claw bases provided with internal septa in the new genus whereas in Thulinius the septa in claw bases are absent.</p></div>	https://treatment.plazi.org/id/9A29DAAEEC315C889DC8F8B99290810C	Public Domain	No known copyright restrictions apply.

V. leg .</p><p>Material examined.</p><p>58 animals, and 11 cysts mounted on microscope slides in Hoyer’s medium; 12 animals mounted on microscope slides in Polyvinyl Lactophenol mounting medium (PVLF); 12 hatchlings mounted on microscope slides in PVLF, 4 exuviae on microscope slides in PVL. 7 animals prepared for SEM. 2 individuals used for DNA sequencing, 1 individual used for WGA and mitogenome sequencing.</p><p>Type depositories.</p><p>Holotype with 5 paratypes (slide CT. 6087 in Hoyer’s); 31 paratypes (slides: CT. 6088–6095 in Hoyer’s); 20 paratypes (slides CT. 6093–6099 in PVL); 7 animals mounted for SEM analysis (Stub No. UNICT- 39) deposited at the University of Catania, Via Santa Sofia 102, Catania, Italy. 7 paratypes (slides: MT.008.01 – 02 in PVL), 32 paratypes (MT.008.03 –08 in Hoyer’s) deposited at the Institute of Systematics and Evolution of Animals (Polish Academy of Sciences), Sławkowska 17, Kraków, Poland</p><p>Animals.</p><p>Body size up to approximately 500 µm (Table 2), with hatchlings ranging from about 120 to 180 µm (Table 3). Hatchlings exhibit the same morphological characters as adults (Fig. 6), although morphometric values differ slightly, the pt values being higher in adults for some measurement of placoids and claws (Tables 2, 3). Before mounting, the animals appeared whitish / transparent and became transparent after mounting in PVLF or Hoyer’s medium. Eyes are present (Fig. 4 A), and the entire cuticle appears finely dotted under SEM (Fig. 3 E). The buccal ring appears divided under PCM (Fig. 4 B), giving the impression of the presence of papular lamellae, but under SEM it appears smooth (Fig. 3 A – D). Five – six papular peribuccal lobes are present (in correspondence to peribuccal lobes), visible only under SEM and only when the buccal cone is fully extended (Fig. 3 A, C).</p><p>The oral cavity armature (OCA) is visible only in SEM and consists of two bands: the first band (probably homologous to the second band of teeth of the Macrobiotoidea) comprises small, rounded teeth (gradually decreasing in density toward the second band of teeth) (Fig. 3 B), second band composed by a single line of small round teeth, slightly bigger than those of the first band (Fig. 3 C, D). Buccal tube with two bends: the first, more pronounced, at the beginning of the anterior portion of the buccal tube, in correspondence with the area bearing the ventral lamina; the second, less pronounced, approximately halfway along the tube (Fig. 4 A). Ventral lamina present (Fig. 4 A, D), with characters described for the genus.</p><p>Typically-shaped stylet furcae (according to Pilato and Binda (2010 b)), each possessing a pair of condyles (symmetrical with respect to the medial axis of the furca) located between the stylet base and the two swellings at the base of the furca (Fig. 4 C).</p><p>Three macroplacoids (length sequence: 2 &lt;3 &lt;1) are present: the first is very long and rod-shaped (more than twice the length of the second), with a slight median constriction; the second, located almost adherent to the first macroplacoid, is granular; and the third is rod-shaped and nearly twice the length of the second (Fig. 4 E).</p><p>Claws are large and slender, similar to those of Thulinius, with humps on the primary branches of the internal claws (Fig. 4 E) and with Br ratio higher in internal claws (mean external / posterior claws = 68.2 %; mean internal / anterior claws = 73.2 %; mean general = 70.1 %. For detailed information see File S 1). Accessory points appear absent under PCM analysis; however, SEM reveals their presence adjacent to either side of the primary branch in all claws (Fig. 5 B, E, G). This overlap with the main branch prevents their observation under light microscopy. Only occasionally, they appear elevated above the primary branch on claws IV under PCM.</p><p>The claw bases on all claws appear internally septate (Fig. 5 C); such septa are internal structures and thus invisible under SEM (Fig. 5 B, G, E).</p><p>Lunulae and pseudolunulae are absent; a long, thin and smooth cuticular bar is present under the claw bases of claws I – III (visible under both SEM and PCM, as observed in Fig. 5 A – E), well-spaced from the claws and not originating from the internal claw (e. g., similar to the cuticular bar observed in the genus Thulinius).</p><p>Moreover, a wrinkled button-like cuticular fold is present above the claws of the I – III pair of legs (Fig. 7 B – D) this structure is well visible under SEM and only sometimes slightly visible with PCM.</p><p>Cysts.</p><p>The animals form cysts that are dark in colour, ranging from dark green to nearly black (Fig. 8). The legs are barely visible under PCM within the external cuticle. The surface of the cyst is covered with numerous folds and wrinkles, which trap a significant amount of sediment (Fig. 8).</p><p>Eggs.</p><p>Laid in the exuvia, with smooth chorion. Whitish / transparent in colour, round in shape and in number of 4–8 per exuvia.</p><p>Additional observations.</p><p>Both sexes (see File S 6 for males stained with orcein) are reported for this species, with no evident secondary sexual dimorphism. Multiple instances of a behaviour in which a single female is surrounded by 2– 5 males that anchor themselves to her body using their mouth have been observed.</p><p>DNA.</p><p>The following DNA sequences are associated with the type population of the new species: 18 S: PV 016871 –2. — 28 S: PV 016873 –4. — COI: PV 017087 –8. — ITS 2: PV 019027 –8. — Mitogenome: PV 030524. — Genomic reads: Bioproject PRJNA 1215272.</p></div>	https://treatment.plazi.org/id/829F0FE6A46E50EF81AEFB5FE3734089	Public Domain	No known copyright restrictions apply.
