F13387D2FF92C105FBC3FD5AFC44363C.taxon	description	Description BODY. Shape oval. Length 2.6 cm. Smooth dorsal surface. Background pigmentation ivory white, darker along the middle dorsal region of the body. Amber dots and thin brushstroke-like lines garnish the dorsal surface. A thin, dark stripe, sometimes interrupted, extends along the central dorsal line (Fig. 2 A). Two delicate marginal folds, separate and pointed, could be interpreted as pseudotentacles. Tentacular eyes scarce and widely dispersed over the tentacles. Cerebral eyes anterior drop-shaped and crossed by the central midline. Marginal eyes only at the anterior part (Fig. 2 B). Ruffled pharynx, in the middle of the body with a central oral pore. Ventral sucker at the posterior part of the body. Male and female genital pore lead in a common genital atrium (Fig. 2 D – E) that opens in the posterior body region after the pharynx (Fig. 2 C). MALE REPRODUCTIVE SYSTEM. Male copulatory organ backwards oriented, with a muscular penis papilla, very muscular seminal vesicle (Fig. 2 C, E) and without a prostatic vesicle, instead a simple glandular epithelium leads into the penis papilla (Fig. 2 D – E). Seminal vesicle rounded, frontal oriented and with thick muscular walls, opening into the ejaculatory duct. Short ejaculatory duct opens into the penis papillae. The male atrium is small and thin, connected to the common atrium. FEMALE REPRODUCTIVE SYSTEM (Fig. 2 C, E). The vagina runs from the common genital atrium and continues dorsally into a narrowed duct that widens into a chamber, the cement pouch. The vagina continues dorsally, then curves posteriorly and ventrally and ends with the entry of the oviducts.	en	Cuadrado, Daniel, Rodríguez, Jorge, Moro, Leopoldo, Grande, Cristina, Noreña, Carolina (2021): Polycladida (Platyhelminthes, Rhabditophora) from Cape Verde and related regions of Macaronesia.

F13387D2FF92C105FBC3FD5AFC44363C.taxon	discussion	Remarks Marcusia alba sp. nov. belongs to the genus Marcusia due to the presence of cerebral, frontal and marginal eyes, male copulatory organ enclosed in a muscular bulb, the absence of prostatic vesicle and the common male and female atrium genital, as well as the common gonopore. The genus Marcusia contained only one species, Marcusia ernesti Hyman, 1953, known from the coast of the Gulf of California (Hyman 1953). Marcusia ernesti and M. alba sp. nov. can be easily distinguished by their coloration patterns. Marcusia ernesti is black or grey with darker splotches and dotted with white spots, only visible in preserved individuals after Hyman (1953), M. alba sp. nov. is ivory white with brownish dots and stripes. The penis papilla is spherical in M. alba and elongated in M. ernesti, with the male atrium being tube-like and longer in the Californian species. Another difference lies in the eyes’ presence and distribution. Marcusia ernesti presents marginal, frontal and cerebral eyes as well as two characteristic eye clusters with diagnostic value (Hyman 1953). Marcusia alba sp. nov., on the other hand, has cerebral, marginal and tentacular eyes, but not frontal eyes or eye clusters. The differences listed are enough to consider M. ernesti and M. alba sp. nov. as two different species of the same genus. Furthermore, the molecular analyses show the genus Marcusia (represented in this case by Marcusia alba sp. nov.) as a genus closely related to Pericelis Laidlaw, 1902 within the family Anonymidae Lang, 1884, but as a clearly independent genus.	en	Cuadrado, Daniel, Rodríguez, Jorge, Moro, Leopoldo, Grande, Cristina, Noreña, Carolina (2021): Polycladida (Platyhelminthes, Rhabditophora) from Cape Verde and related regions of Macaronesia.

F13387D2FF90C11BFB69FC24FB17372B.taxon	description	Description BODY. Shape elongated. Length 0.5 cm. Smooth dorsal surface; background pigmentation ivory white, darker along the middle dorsal region of the body between the cerebral eyes and the posterior end of the body. In the posterior middle end it shows a large conspicuous black spot. Small black dots on the entire dorsal surface (Fig. 3 E). Two marginal tentacles, separate. Tentacular eyes scarce and widely dispersed between the tentacles. Cerebral eyes arrow-shaped located by the central midline (Fig. 3 F). Bell-shaped pharynx located in the first body half. Ventral sucker in the middle of the body. Male and female genital pores well separated and located after the pharynx (Fig. 3 G – H). MALE REPRODUCTIVE SYSTEM. Male copulatory organ oriented forward. The muscular prominent penis papilla houses a conical, elongated stylet of pseudosclerotized nature. The rounded and well developed prostatic vesicle joins transversally with the sperm duct and lies over the penis papilla (Fig. 3 H). Muscular seminal vesicle oval, dorsally located and caudo-frontally oriented. The vasa deferentia join at the ventro-caudal region of the vesicle and the sperm duct open ventro-frontally. Seminal and prostatic vesicles open together into the proximal region of the developed penis papillae. The male atrium surrounded the penis papillae and opens near the posterior end of the pharynx. FEMALE REPRODUCTIVE SYSTEM. Atrium elongated and highly ciliated, continues dorsally into the long but not ciliated vagina externa. The vagina externa narrows into a non-ciliated small cavity that continues in the vagina interna. It presents a widened epithelium and ends with the entry of the oviducts (Fig. 3 H). Cement and shell glands lie around the female atrium, vagina externa and distal region of the vagina interna, but opens into the small cavity (pouch) between both vaginas.	en	Cuadrado, Daniel, Rodríguez, Jorge, Moro, Leopoldo, Grande, Cristina, Noreña, Carolina (2021): Polycladida (Platyhelminthes, Rhabditophora) from Cape Verde and related regions of Macaronesia.

F13387D2FF90C11BFB69FC24FB17372B.taxon	discussion	Remarks Prostheceraeus crisostomum sp. nov. belongs to the genus Prostheceraeus due to the presence of cerebral, frontal and marginal eyes, true anterior tentacles, bell-shaped pharynx, the male copulatory system with prostatic vesicle, penis armed whit stylet and the presence of multiple uterine vesicles. The genus Prostheceraeus comprises 10 species, mainly characterized by coloration pattern, with colorful pigmentations and dorsal longitudinal lines of different widths, as in P. fuscolineatus Dixit, Raghunathan & Chandra, 2017, P. roseus, P. pseudolimax Lang, 1884, P. giesbrechtii, P. vittatus (Montagu, 1815) and P. zebra (Hyman, 1955) or with fine, transversal lines as in P. crozieri (Hyman, 1939). Three other species of Prostheceraeus show a color pattern free of lines or bands: P. albocinctus Lang, 1883, P. moseleyi and P. rubropunctatus Lang, 1884. These three species, together with P. crisostomum sp. nov., have a dotted pattern, but the background colors are different in the four species: caramel brown background with white or whitish spots and white marginal line in P. albocinctus, blue-gray or cream background with black dots and yellow marginal band in P. moseleyi and finally P. rubropunctatus with a pink to reddish background color, white dots and without marginal band. The base coloration of P. crisostomum is similar to P. albocinctus, but much clearer and almost ivory; the dorsal points are black like in P. moseleyi and lacks a marginal line or band similar to P. rubropunctatus. All these differences delimit P. crisostomum sp. nov. as a new species of the genus Prostheceraeus.	en	Cuadrado, Daniel, Rodríguez, Jorge, Moro, Leopoldo, Grande, Cristina, Noreña, Carolina (2021): Polycladida (Platyhelminthes, Rhabditophora) from Cape Verde and related regions of Macaronesia.

F13387D2FF8EC118FB57FD48FBF1317A.taxon	description	Description BODY. Shape oval. Length 2.3 cm. Smooth dorsal surface. Background color dark to velvety brown with white dots and spots that draw a longitudinal line along the body axis. One thin bright yellow external line and another internal and black line surround the entire body margin. The yellow one is interrupted at the pseudotentacles level (Fig. 3 E – F). Marginal body edges lined with transversal whitish elongated drops (Fig. 3 F). Ventral coloration dark grey to black. Ventral sucker in the middle of the body (Fig. 3 G). Pseudotentacles constitute two simple folds that present each of them a small cluster of tentacular eyes in their margin. Round cluster of cerebral eyes present and surrounded by a spot of white pigment. Pharynx ruffled, butterfly-shaped and located at the anterior third of the body. Oral pore, female and male gonopore close to each other and located at the anterior end (Fig. 3 G). Male and female genital pores located after the pharynx in the anterior half of the body (Fig. 3 H – I). MALE REPRODUCTIVE SYSTEM. Male genital pore between the posterior lobes of the ruffled pharynx. Male copulatory organ dorso-ventrally orientated consists in a prostatic vesicle and a very muscular seminal vesicle, as well as a penis papilla armed with a stylet (Fig. 3 H – I). Vasa deferentia open separately into the seminal vesicle. Seminal vesicle rounded, frontally oriented and lined with a thick muscular wall. Prostatic vesicle rounded, muscular and smaller than the seminal vesicle. Sperm duct muscular and long, extends frontally to join the prostatic duct inside the proximal end of the conical stylet. The short ejaculatory duct appears surrounded by the stylet cone and the penis sheath. The male atrium is wide and tetra-folding (fork-like) as characteristic of the genus (Fig. 3 I). FEMALE REPRODUCTIVE SYSTEM. With a short muscular vagina, backwards oriented and surrounded by cement glands.	en	Cuadrado, Daniel, Rodríguez, Jorge, Moro, Leopoldo, Grande, Cristina, Noreña, Carolina (2021): Polycladida (Platyhelminthes, Rhabditophora) from Cape Verde and related regions of Macaronesia.

F13387D2FF8EC118FB57FD48FBF1317A.taxon	discussion	Remarks The genus Pseudoceros comprises approximately 89 species with similar copulatory organs, but bright and unique coloration patterns. However, within these patterns some taxa share evident similarities. Pseudoceros rawlinsonae var. galaxy shares with P. bicolor Verril, 1902, P. mororum and P. rawlinsonae Bolaños, Quiroga & Litvaitis, 2007 the brown background and one whitish, broad marginal band, but in P. bicolor the marginal band is wide with inner waves (Litvaitis et al. 2010: fig. 4 a – i); P. rawlinsonae shows, in addition to the wide band, a thin orange line (Litvaitis et al. 2010: fig. 4 j – p); in P. mororum the whitish band is interrupted and drop-shaped and additionally, two orange marginal stripes border the entire body (Cuadrado et al. 2017: fig. 6 a – b); finally, the Cape Verdean species shows, together with the drop-shaped white band, two black and orange thin lines (Fig. 3 E – F). Although the four previously mentioned species can be clearly differentiated due to their coloration, this is not the case in the molecular analysis (Fig. 8). In both the Bayesian and Maximum Likelihood analyses, individuals from Cape Verde appear closely related to P. rawlinsonae, so much so that the separation of both populations (the Cape Verdean population and the Caribbean population) is only possible at the level of variety, not of species. Therefore, we determined the individuals from Cape Verde as a variety within the species P. rawlinsonae. Nonetheless, we want to emphasize that the decision to maintain this population (organisms) as a ‘ variety’ of the species P. rawlinsonae is the sole and exclusive responsibility of the authors. We are aware that ‘ variety’ is not a taxonomic category (according to ICZN) and that therefore it will remain a non-existent species until molecular analyses allow us to consider it as such.	en	Cuadrado, Daniel, Rodríguez, Jorge, Moro, Leopoldo, Grande, Cristina, Noreña, Carolina (2021): Polycladida (Platyhelminthes, Rhabditophora) from Cape Verde and related regions of Macaronesia.

Female apparatus with vagina bulbosa and Lang´s vesicle. Parviplana comprises 3 species, P. hymani Faubel, 1983, P. jeronimoi Pérez-García, Noreña & Cervera, 2018 and P. lynca (Du Bois-Reymond Marcus, 1958). Parviplana lynca can be easy and clearly distinguished from the other two species by the presence of nuchal tentacles, exclusive of this species. Parviplana hymani can be distinguished from P. sodade sp. nov., by the vas deferens which opens together into the seminal vesicle, and the prostate vesicle not included into de penis bulb. Parviplana sodade sp. nov. possesses more similarities with P. jeronimoi. Both species share the penis sheath and more than 25 cerebral eyes, but clear differences separate them. Parviplana jeronimoi has a fleshy appearance and amber pigmentation. The size is also noticeable different, P. jeronimoi can reach lengths of 20 mm, while P. sodade in full mature state does not reach 8 mm. Parviplana jeronimoi also presents vasa deferentia joined in a single vas deferens, a small female atrium and a corrugated surface between the two genital pores, characteristics not present in P. sodade.	en	Cuadrado, Daniel, Rodríguez, Jorge, Moro, Leopoldo, Grande, Cristina, Noreña, Carolina (2021): Polycladida (Platyhelminthes, Rhabditophora) from Cape Verde and related regions of Macaronesia.

F13387D2FF8CC11FFB2BFAA4FC1E374D.taxon	discussion	Remarks Euplana claridade sp. nov. belongs to the genus Euplana due to the absence of tentacles, prostatic vesicle and Lang´s vesicle, and presence of a true seminal vesicle and elongated coiling ejaculatory duct. The genus Euplana encompasses 3 species, E. carolinensis Hyman, 1940, E. gracilis Girard, 1853 and E. hymanae Marcus, 1947. The three species can be differentiated through the eyes number and disposition of them. E. gracilis and E. carolinensis present four cluster of eyes, two cerebral and two tentacular; E. hymanae and E. claridade sp. nov. only show two groups of cerebral eyes. Within the reproductive system another differences can have founded, E. gracilis and E. hymanae present a small, short male atrium and a backwards oriented vagina externa, while E. carolinensis and E. claridade sp. nov. share a long tubular male atriumand a forward directed vagina externa. Both species differ mainly in the male copulatory organ. The ejaculatory duct in E. carolinensis is wide and straight and by E. claridade sp. nov. is narrow and sinuous. Furthermore, the penis papilla is very short in E. carolinensis, while in E. claridade sp. nov. it is longer in comparison. On the other hand, the seminal vesicle is practically non-existent in E. claridade sp. nov., represented by the confluence of the two vasa deferentia, while in E. carolinensis it is a well-developed seminal vesicle, surrounded by circular muscles and in which the vas deferens empties proximally.	en	Cuadrado, Daniel, Rodríguez, Jorge, Moro, Leopoldo, Grande, Cristina, Noreña, Carolina (2021): Polycladida (Platyhelminthes, Rhabditophora) from Cape Verde and related regions of Macaronesia.

F13387D2FF8AC11CFBC2FC8BFB33364E.taxon	discussion	Remarks Stylochus salis sp. nov. belongs to the genus Stylochus due to the presence of gonopores separate and arranged in the second body half. With large and much ruffled pharynx. Tentacular, cerebral, marginal, and often frontal eye-spots present. Male copulatory apparatus with seminal vesicle and papillate penis. Lang’s vesicle lacking (after Faubel 1983). Stylochus salis sp. nov. clearly differs from other known species of Stylochus Ehrenberg, 1831 by its peculiar cream pigmentation bordered with the internal orange outline and the white / creamy outer band. The color of the eastern Atlantic known species (S. alexandrinus, S. castaneus Palombi, 1939, S. neapolitanus, S. plessissii Lang, 1884, and S. suesensis Ehrenberg, 1831) varies between brown, light brown, reddish or beige and spotted as in S. neapolitanus. None of them present a continuous (or discontinuous) marginal line. The most conspicuous anatomical feature is the location of the oral pore, very close to the gonopore, clearly different from the central position of the oral pore in this genus. The peculiar location of the oral and genital pores distinguishes S. salis sp. nov. from the remaining species. Such a close location of the pores could only be found in the genus Latocestus Plehn, 1896 (Latocestidae, Stylochoidea).	en	Cuadrado, Daniel, Rodríguez, Jorge, Moro, Leopoldo, Grande, Cristina, Noreña, Carolina (2021): Polycladida (Platyhelminthes, Rhabditophora) from Cape Verde and related regions of Macaronesia.

Cerebral and tentacular eyes, scattered between the small tentacles (Fig. 5 F). Ruffled pharynx, well developed, extending along ⅔ of the body. Male and female genital pores located in the posterior half of the body, together, but clearly separated. MALE REPRODUCTIVE SYSTEM. Male copulatory system backwards oriented, with a small penis papilla. Prostatic vesicle surrounded by muscular layers and lined with fingered granular lining, most probably polyglandular (Fig. 5 G – H). Seminal vesicle divided into two sections. A muscular and elongated proximal section, and a more rounded distal section provided with a thin wall. Both regions separated by muscle narrowing (Fig. 5 H). The distal section leads to the seminal duct that opens into the prostatic duct and forms a short ejaculatory duct. The two vasa deferentia dilated to form spermatic vesicles, open into the proximal section. Male atrium small, englobing a short penis papilla (Fig. 4 H). FEMALE REPRODUCTIVE SYSTEM. Apparatus simple and backwards oriented. Comprises an elongated tube without clear differentiation between external and internal vagina and ends in a small widening, without Lang’s vesicle.	en	Cuadrado, Daniel, Rodríguez, Jorge, Moro, Leopoldo, Grande, Cristina, Noreña, Carolina (2021): Polycladida (Platyhelminthes, Rhabditophora) from Cape Verde and related regions of Macaronesia.

F13387D2FF88C112FB26FECBFCA3346C.taxon	discussion	Remarks The new species belongs to the genus Distylochus due to the presence of few scattered marginal, tentacular and cerebral eyes. Gonopores together and are located near the posterior end. Male apparatus with a short papilla and unarmed. Seminal vesicle configured in two regions, following the “ doublevesicle-system ” after Faubel (1983) and female apparatus simple, without Lang’s vesicle. There are currently only three known species for the genus Distylochus: D. pusillus (Bock, 1913) recorded for Hong Kong, D. martae (Marcus, 1947) in Brazil and D. isifer (Du Bois-Reymond, 1955) also from Brazil. These species were described on fixed specimens, therefore the colors are unknown, but apparently and after the original descriptions, they have pale pigmentation that contrast sharply with the orange-vermilion colors of the new species. The most conspicuous difference of the new species is the disposition of female and male gonopore. In Distylochus fundae sp. nov. the gonopores are clearly separated, while in the Brazilian species are common and in the Chinese species are very close together.	en	Cuadrado, Daniel, Rodríguez, Jorge, Moro, Leopoldo, Grande, Cristina, Noreña, Carolina (2021): Polycladida (Platyhelminthes, Rhabditophora) from Cape Verde and related regions of Macaronesia.

F13387D2FF80C12AFB72FD05FBA7307D.taxon	description	Molecular analysis The main purpose of the 28 S analysis was to confirm the determinations made from the morphological study and verify the relationships among similar species. The recovered topology by both trees, Bayesian Inference (BI) as well as Maximum Likelihood (ML) strongly supports the monophyly of the suborders Acotylea and Cotylea (Fig. 8; Acotylea: BPP (Bayesian posterior probabilities) = 1 and BS (Bootstrap values of ML analysis) = 73, Cotylea: BPP = 0.98, BS = 100). Within Acotylea, the monophyly of Leptoplanoidea (BPP = 1, BS = 97) and Stylochoidea (BPP = 1, BS = 73) is well supported. Callioplana marginata Stimpson, 1857 considered within the superfamily Stylochoidea appears isolated with the highest support (BS = 100). As a sister group of Leptoplanoidea, there is a clade of species: Ilyella gigas (Schmarda 1859), Discocelis tigrina (Blanchard, 1847), Adenoplana evelinae Marcus, 1950, Amemiyaia pacifica Kato, 1944 and Phaenocelis medvedica Marcus, 1952 showing low support and not clearly grouped (Fig. 8). The main group of Leptoplanoidea encloses the family Leptoplanidae, with the genera Leptoplana Ehrenberg, 1831 and Armatoplana Faubel, 1983, and the family Notoplanidae Marcus & Marcus, 1966 with the genera Notoplana Laidlaw, 1903 and Notocomplana Faubel, 1983. Pseudostylochus Yeri & Kaburaki, 1918 and Koinostylochus Faubel, 1983 appear together and belong to the family Pseudostylochidae Faubel, 1983. Within Stylochoidea, four main clades are recovered: family Stylochidae with the genera Stylochus, Imogine Girard, 1853 and Paraplanocera Laidlaw, 1903 (see the Discussion); family Latocestidae Laidlaw, 1903 with Leptostylochus Bock, 1925 and Latocestus; family Hoploplanidae StummerTraunfels, 1933 with Hoploplana Laidlaw, 1902 and finally family Planoceridae with Paraplanocera Laidlaw, 1903 and Planocera. Callioplana marginata can be considered a sister group of Stylochoidea. Within the suborder Cotylea, the families Cestoplanidae Lang, 1884, Pericelidae Laidlaw, 1902 and Anonymidae represented by the genera Cestoplana Lang, 1884 (BPP = 1, BS 100), Pericelis (BPP = 1, BS 100) and Anonymus (BPP = 1, BS 100), respectively are presented as isolated groups. While Boninia Bock, 1923, Chromyella Correa, 1958 and Theama Marcus, 1949 form a well-supported group (BPP = 1, BS = 100), although currently belonging to separate families and not specifically related to each other. After Anonymidae, we find a well-supported branch (BPP = 0.9, BS = 95) that encompasses the families Prosthiostomidae Lang, 1884, Euryleptidae and Pseudocerotidae. This branch is, in turn, divided into two main branches (both supported by maximum values: BPP = 1, BS = 100) where Prosthiostomidae is separated from Euryleptidae and Pseudocerotidae, families with a clear relation.	en	Cuadrado, Daniel, Rodríguez, Jorge, Moro, Leopoldo, Grande, Cristina, Noreña, Carolina (2021): Polycladida (Platyhelminthes, Rhabditophora) from Cape Verde and related regions of Macaronesia.
