The right excretory plate is 165–218 µm (183±25) long and 90–130 µm (115±30) wide whereas the left excretory plate is 106–130 µm (120±10) long and 70–100 µm (85±13) wide.</p><p>ALIMENTARY SYSTEM: Mouth surrounded by a large muscular sphincter 100–140 µm (126±29) long by 220–257 µm (230±27) wide; pharynx 200–230 µm (226±56) long by 420–465 µm (447±55) wide (Fig. 4A); intestine saccular, without septations (Figs 2C–D, 3A).</p><p>GLANDS: Bunches of rhabditogenic glands are present in the lateral sides of the body encompassing from the pharynx to the middle level of the adhesive disc. Haswell’s cells in front of the eyespots and the brain (Figs 2C–D, 4B).</p><p>FEMALE REPRODUCTIVE SYSTEM: Gonopore mid-ventral, in the posterior third of the body (Fig. 3A); surrounded by a muscular sphincter. Ovary unpaired, small and lying adjacent to the vesicula resorbens; vesicula resorbens is elliptical and indenting towards the intestinal sac; vagina large and muscular, connects to the spacious genital atrium (Figs 3B, 5A). Eggs yellow, without peduncle, deposited over the host carapace and on the chelipeds, 500–550 long (527±21), 220–310 µm wide (258± 38), slightly reniform, polar filament extremely short (Fig. 5D–E).</p><p>MALE REPRODUCTIVE SYSTEM: Two pairs of testes are present; anterior pair round and lateral to intestine sac; posterior pair always lateral and posterior to intestine, oblique, elliptical; bigger than anterior testes (Figs 2D, 3A). Right anterior testis 123–236 µm (196±51) long, 102–139 µm (122±15) wide; right posterior testis 321–399 µm (348±37) long, 156–240 µm (193±36) wide; left anterior testis 162–226 µm (195±26) long, 109–126 µm (118±7) wide; left posterior testis 312–379 µm (340±31) long, 176–227 µm (195±23) wide. Vasa deferentia wide swollen, uniting separately to a large, pyriform, thick-walled, seminal vesicle. Ejaculatory sac present, with narrowed neck. Prostate bulb not well defined, as a continuation of the cirrus base (Figs. 3B, 5A). Cirrus almost straight (Fig. 5A–B), 182 µm long; 128 µm shaft length; 48 µm wide at proximal end; 15 µm wide at distal end. Introvert 54 µm long, swollen and provided with numerous spines. The reversible spined introvert has an evident unspined distal region (Fig. 5C). The ratio between total length of cirrus and maximum width of shaft’s proximal end 3.79; ratio between total length of cirrus andtotallengthofintrovert 3.37.Introvertspines very small, in approximately 30–40 parallel rows arranged slightly diagonal to the long axis of the introvert (Fig. 5C).</p></div>	https://treatment.plazi.org/id/9A7587F6FFE7F13DFD760575C4ADF988	Public Domain	No known copyright restrictions apply.
