8D23230D2121E1338A5EF998FE66FAFC.taxon	description	Description. Animals 0.8 - 0.9 mm long (Fig. 1 A, B). General morphology as in Hu et al. (2019). Central two quarters of its body completely dark-blue because of dorsal subepidermal pigment granules, anterior and posteri- or quarter with brown-yellow parenchymatous pigment granules (Fig. 1 B, C), particularly around paired ovaries (o, Fig. 1 B, C). Cone-shaped proboscis about 140 μm long (p, Fig. 1 B). Two black eyes situated posterior to proboscis (e, Fig. 1 B). Pharynx about 120 μm in diam. and at 30 - 40 % of body length (ph, Fig. 1 B). Vitellaria poorly visible, stretching from pharynx to posterior end of animals (vi, Fig. 1 B). One of the specimens carries a 200 μm-long fertilized egg (eg, Fig. 1 B). Male system consists of paired testes, situated midbody beside and behind pharynx (t, Fig. 1 B), paired seminal vesicles (sv, Fig. 1 B), and prostate stylet type III lo- cated inside male atrium (st, Fig. 1 B). Stylet is about 43 μm long and has a complex morphology. Proximal base (“ skirt ” in Karling & Schockaert, 1977) is asymmetri- cally bowtie-shaped and carries two pairs of overlapping plates. Two plates of each pair differ in size and shape and are attached to each other along full length of fortified axis (“ tongue ” in Karling & Schockaert, 1977) arising from base. Largest plate of first pair (p 1, Fig. 1 D) is more or less triangular with smooth straight edge on one side, smooth rounded corner (“ blade ” in Karling & Schockaert, 1977), and one fringed edge on the other side. Much smaller plate of first pair (p 2, Fig. 1 E) has one more pronounced serrated edge over short distance followed by protruding rounded corner (“ blade ”). Largest plate of second pair (p 3, Fig. 1 F) is similar to p 1, but somewhat smaller and without rounded corner. Smallest plate of second pair (p 4, Fig. 1 G) also has one more pronounced serrated edge, but over longer length than p 2 and lacking protruding rounded corner.	en	Kim, Kimi, Van Steenkiste, Niels W.
