The species name corolla is a Latin noun meaning “ flower crown ”, referring to the radially arranged prostatoid organs around the male atrium that look like a flower.	en	Liu, Hai-Long, He, Bing-Bing, Wang, An-Tai, Li, Shuang-Fei, Zhang, Yu (2026): An integrative description of a new interstitial species of Boninia (Platyhelminthes, Polycladida) from the South China Sea.

0A66519D3A9E521D978DB5CAB7B76E7B.taxon	description	Description. The worm is flat and slender, translucent milky-white, and with tapering posterior end (Fig. 1 A). Anesthetized specimens are 14 – 26 mm long and 0.8 – 1.2 mm wide. A pair of fine, flexible tentacles (approximately 0.5 mm long) is present on either side of head (Fig. 1 B). The tentacular eyes are absent. A pair of cerebral eyespots is symmetrically located at the anterior margin of the brain, with the two eyespots in each pair lying closely together (Fig. 1 B). Marginal eyespots, 28 – 48 in number, are evenly distributed along the base of the tentacles, extending to the posterior margin of the brain (Fig. 1 B). The intestine is highly branched and darkened by gut contents. A ruffled pharynx is 7 – 11 mm long and is located at or slightly posterior to the center of the body (Fig. 1 A). The mouth opens slightly anterior to the center of the pharynx. The male pore lies approximately 1 mm behind the posterior end of the pharynx (Fig. 1 D). The female pore opens 1.5 – 2.0 mm posterior to the male pore (Figs 1 D, 2 F). An adhesive organ is located at the posterior end of body on ventral side. The male copulatory apparatus is comprised of a seminal vesicle, an interpolated prostatoid, a penis papilla, and 9 – 15 prostatoid organs. A pair of sperm ducts extends along each side of the midline, curves at the posterior region of the pharynx, and enters the seminal vesicle separately (Fig. 1 D). The seminal vesicle is somewhat ovoid (Fig. 2 A, F), with both ends elongated, and the distal end opening into the prostatic vesicle (Fig. 2 A, F). The seminal vesicle is lined with a flat, ciliated epithelium and surrounded by a layer of very strong circular muscle fibers, especially near the distal part; a few longitudinal muscle layers lie external to the circular fibers (Fig. 2 A, F). The prostatic vesicle is nearly heart-shaped (50 μm in its long axis, 25 μm in its short axis), lined with high epithelium, and connects to penis papilla (Fig. 2 A, F). The penis papilla is unarmed and projects into the male atrium (Fig. 2 A, F). The inner wall of the male atrium is ciliated. The individual ducts of 9 – 15 prostatoid organs are radially arranged into a single girdle around the male atrium (Figs 1 C, 2 C) and open into inner area of the male atrium (Fig. 2 A, F). Each pyriform prostatoid organ bears a sclerotized stylet (approximately 60 μm in length) (Figs 1 C, 2 D). Extracapsular glands produce glandular secretion into each prostatoid organ (Fig. 2 C, D, F). The ovaries are dorsally arranged in two rows, one on each side of the body, extending from behind the brain to almost the posterior end of the body. A pair of uterine canals, posterior to the male copulatory organ, are connected through short lateral branches to multiple uterine vesicles (approximately 10 – 17 in number on each side) (Fig. 1 D, E). Each uterine canal widens distally to form a large posterior dilation filled with eggs (Fig. 1 D, E). The uterine canals connect to the vagina immediately anterior to the entrance of Lang’s vesicle (Figs 1 D, 2 B, E, F). The Lang’s vesicle is elongated (240 μm in its long axis; 150 μm in its short axis) and is lined with ciliated epithelium (Fig. 2 B, E). The ciliated vagina extends anteriorly for a short distance, then turns ventrally to dilate and form a shell chamber, which is surrounded by numerous cement glands (Fig. 2 B, E). The vagina continues its course to open externally through the female genital pore.	en	Liu, Hai-Long, He, Bing-Bing, Wang, An-Tai, Li, Shuang-Fei, Zhang, Yu (2026): An integrative description of a new interstitial species of Boninia (Platyhelminthes, Polycladida) from the South China Sea.
