DERIVATIO NOMINIS.
Dedicated to the German Rutelinae specialist Johann W. Machatschke, who first recognized this taxon as distinct.
DISTRIBUTION.
Known from the Republic of Congo.
BIOLOGY.
The species was collected in the month of November (original description).
NOMENCLATURAL REMARKS.
The species Popillia congoana Machatschke, 1975 was described based on specimens from Republic of Congo and is currently treated as a valid species. However, Popillia congoana Machatschke, 1975 is a junior homonym of Popillia congoana Kolbe, 1894 described from the Democratic Republic of Congo. The rejected primary junior homonym has no known available and potentially valid synonyms and is replaced by the new substitute name Popillia johanni following ICZN (1999).
The two species belong to different species groups. Popillia congoana Machatschke, 1975 belongs to the interpunctata species group as defined by (Machatschke, 1957) and characterized by: costae not convex, pygidium with a transverse band of squamous decumbent setae and parameres short of different sizes, the right paramere more sinuous outwardly (drawing of aedeagus (fig. 10A), is taken from original publication (Machatschke, 1975) is close to Popillia interpunctata Erichson, 1842; Popillia congoana Kolbe, 1894 (Fig. 10B, C) was not listed by Machatschke (1957). However, the species belongs to the femoralis species group, which he characterized by strongly convex costae, pygidium with two separated small tufts of decumbent squamous setae and the apex of parameres elongated, apex of median lobe always visible dorsally; it is close to P. smaragdina Kraatz, 1892.

REMARKS.
After the examination of the female holotype of Adoretus divergens Benderitter, 1928 it is deemed conspecific with Adoretus calvusoides Limbourg, 2019. Therefore, the latter species becomes a new junior subjective synonym.

Description and synonymy in Van Name 1945 Station: AM 0 1 (MNHN S1 BOT.A 39)
This shallow water species has a worldwide distribution in tropical waters (Sheets et al 2016) and has been often recorded in the West Indies region. Van Name (1945) wrote a complete description of the anatomical characters and figures were made by Monniot C. (1983) for Guadeloupe specimens. The Martinique samples were collected on sea grass in Fort de France Bay.

E. tincta is easily recognizable with its red zooids included in a thin sheet of common tunic. The body wall is thin with inconspicuous musculature (Fig. 3). This species was previously collected from the Caribbean islands, Brazil and Florida (Van Name 1945; Van der Sloot 1969; Monniot C. 1983; Paiva et al 2015 and bibliography). It has also been cited from the Indian Ocean.

A colony of 12 zooids was settled on Halimeda algae. The individuals are distant from each other and only linked by stolons (Fig.4A). The bodies are upright and the siphons apical. The tunic is incrusted with sand. The body wall is light brown in formalin. Eighty tentacles were counted in one of the zooids. The dorsal tubercle is button like. The brown branchial sac (Fig.4B) has 3 folds on the right side and only 2 on the left side. All zooids are immature. The gut forms a single open loop loosely attached to the body wall. Seven folds can be seen on the visible side of the stomach which has a comma-like caecum. The anus has 2 lobes. There are 4 to 6 endocarps on the right side of the body wall and 3 on the left side.
Without gonads the species identification remains doubtful; it is based on a comparison with specimens collected in Bermuda (Monniot C. 1972) and in Guadeloupe (Monniot C. & F. 1984). They have the same colony shape, gut, branchial sac and endocarps in the zooids. Other specimens of S. sabulosa are present in the MNHN collection recorded from Florida in 1999 and from Brazil during the “Calypso” campaign in 1961.

Station: AR 367 (MNHN S1 POL.A 58)
The zooids 1cm long are upright above a basal sheet and tightly linked together by their lateral side (Fig. 6B). The tunic is thin transparent and entirely covered with sand and mud, without epibionts. The siphons are not protruding and have 4 lobes, the oral one apical and the atrial more dorsal. Each siphon has an internal velum spotted with crystalline inclusions. This structure is the same as in P. anguinea. The oral tentacles are in 2 orders of size. The prepharyngeal band in a single rod is distant from the tentacle ring and draws a wide V (Fig. 6A). The prepharyngeal area has no papillae. The dorsal tubercle is button like and opens anteriorly in a C. The body wall is marbled (Fig. 6A) and thin with a weak network of muscular fibres. There are no endocarps. The branchial tissue is thin (Fig. 6A). The dorsal lamina is long and low with a smooth edge. There are 4 branchial folds on each side (Fig.6A). The formula of one zooid on the right side is:
E-6 (10) 5 (14) 5 (14) 4 (12) 1-DL
As in the Mediterranean specimens there is always a single longitudinal vessel between the dorsal lamina and the first branchial fold of the right side (Fig. 6A). This is the principal and constant difference with Polyandrocarpa anguinea which has several vessels in this place instead of one. The stigmata are crossed by parastigmatic vessels. The digestive tract occupies a small part of the left body side (Fig. 6A). The stomach is olive shaped with longitudinal folds and without caecum; the intestine is isodiametric, the primary loop is widely open and the rectum is long. The anus has 8 to 12 lobes. The gut is loosely attached to the body wall by a few trabeculae. The gonads were not fully mature. In one specimen 9 polycarps are on the right side and 7 on the left not arranged in lines (Fig. 6A). Each polycarp is elongated, the ovary on the internal side and several testis vesicles external in a double line. The polycaps hang between the branchial sac and the body wall attached by trabeculae.
All characters of the Martinique specimens are the same as those described from the Mediterranean Sea. The distribution of this species is presently limited to these two regions. A discussion about the different species of Polyandrocarpa was given in Monniot F. (2016a).

The zooids are basally included into a common tunic or only linked by stolons (Fig. 9C). In formalin the tunic is grey naked and resistant. Zooids have different sizes; the largest is 4mm long. The siphons are close together with their aperture in a cross. The body wall is thin with a network of thin muscular fibres. There is an oral velum at the top of about 30 oral tentacles in two orders of size. The prepharyngeal double band is not curved dorsally. The dorsal tubercle in button opens in a hole. The branchial sac (Fig. 9B) has the same structure as in specimens described from the Mediterranean Sea (Brunetti & Mastrototaro 1994; Monniot F. 2016a). There are 4 branchial folds, the most ventral smaller. The most dorsal fold on the right side moves apart from the dorsal lamina posteriorly. There are some parastigmatic vessels. A branchial formula is:
E-(3) 1 (6) 1 (6) 1 (7) 1- DL -(6) 1 (7) 1 (7) 1 (4) - E
The stomach is short with a curved caecum (Fig. 9A). There is a single round endocarp inside the primary gut loop. Mature gonads were found only in the largest zooid, with 7 polycarps on the right side and 4 on the left side. In each polycarp there are 2 lines of testes against the body wall. Most of the specimens are not fully mature and buds are present on the stolons (Fig. 9C).
Globally distributed (Brunetti & Mastrototaro 1994; Lambert and Lambert 2003; Monniot F. 2016a) P. zorritensis is present in the Gulf of Mexico, Florida, southern California, Hawaii, Galapagos, Brazil, Mediterranean Sea, Japan and numerous other locations.

The thin encrusting colonies are grey with a transparent tunic. The anatomy is that described by Van Name (1945), Monniot C. (1983), Monniot C. & F. (1997). The branchial structure is characteristic; there are 4 longitudinal vessels on each side but 2 vessels on the left side do not reach the base of the branchial sac but join the dorsal lamina (Fig. 10A). There are usually 9–11 rows of stigmata, sometimes 9 as in Fig. 10A. The testis vesicles are lobed and this peculiarity represents the main difference with S. viride living the same habitat. The distinction between both species is not clear in the literature. A discussion concerning the Caribbean Symplegma species was given by Monniot C. (1983) and also by Monniot C. & F. (1997) with a new record of S. brakenhielmi from the Arabian Gulf. The general geographic distribution according to several authors’ citations cannot be ascertained.

The zooids are coalescent in thin sheets. No colour remains in formalin but there is an obvious design of a network of blood vessels. The zooids are easily removed from the tunic as only attached by the apical oral siphon and atrial siphon in the middle of the dorsal side. The anatomy is described in Monniot C. (1972) and is the same here. In Martinique also the colonies have separate sexes. They are immature (Fig. 10B) or with large ovaries and incubated tadpoles and no testis lobes were found. Separated sexes and brancial vessels differentiate S. rubra from S. brakenhielmi. In S. rubra the first longitudinal vessel on the left side extends to the oesophagus aperture when in S. brakenhiemi it joins the dorsal lamina at mid length (Fig.10A).
S. rubra is recorded from the Caribbean area down to Brazil (Rocha & Costa 2005) but also in the Indian Ocean (Monniot F & C. 1997, Tanzania; Monniot F. 2012, Madagascar).

The network of tunic blood vessels is visible through the thin tunic. The description is the same as for S. brakenhielmi except for the gonads. Here the 2 testis vesicles on each side of the ovary are in a simple ovoid lobe as figured in Monniot C. (1983) for specimens from Guadeloupe. Descriptions of specimens from different locations in the literature do not allow to ascertain a geographic distribution outside the Caribbean area.

The body is ovoid in a soft tunic more or less covered with epibionts and sediment. The body wall is transparent with a thin muscular network and some stronger fibres issued from the siphons (Fig. 11A). Both siphons have a large velum (Fig. 11A). The oral tentacles are thin and numerous in 3 sizes. The dorsal tubercle opens in a C with horns sometimes rolled. There are no papillae on the prepharyngeal area. The dorsal lamina with a plain edge becomes higher posteriorly. There are 4 high branchial folds on each side (Fig. 11B). One formula is:
E -3 (13) 3 (5) 3 (13) 3 (12) 2 - DL- 2 (9) 3 (12) 3 (15) 3 (12) 3 - E
There are parastigmatic vessels. The alimentary canal is attached to the body wall by trabeculae. The stomach is pear shaped with oblique folds and a caecum. The intestine in a closed loop contains a round endocarp (Fig.11A); there are no endocarps on the body wall. The anus has 8 lobes. The gonads are numerous on each side with a characteristic shape (Fig. 11A). The round polycarps are distributed along transverse lines (Fig. 11A). Each contains a central ovary partially encircled by testis vesicles. The sperm ducts converge to the polycarp centre and unite in a short tube protruding in the atrial cavity. A circle of thread-like tentacles lies at the base of the atrial velum.
First described from the eastern Atlantic by Michaelsen (1914), P. arnoldi was found again in this region from Cabo Verde (MNHN collection). It has been recorded several times in the Western Atlantic (Van der Sloot 1969; Monniot C. 1983; Rocha et al 2012) but was also found in the Indian Ocean (Monniot C. 2002)

The ascidians were fixed by their ventral or posterior side. The tunic has irregular superficial swellings and occasionally wears epibionts and sediment. The oral siphon is apical and the atrial at 1/3 of the body length; they are not protruding. In life a red line at the rim of the siphons disappears in formalin. The body wall is thin with a network of thin muscular fibres. The tentacles are numerous in 3 orders of size. The dorsal tubercle is variable in shape either S or U opening anteriorly. There are 4 branchial folds on each side (Fig.12 A’, 12B’) with the longitudinal vessels more spaced on their ventral side. The formula of a specimen 3cm large is:
R E- 2 (8) 3 (12) 3 (12) 3 (12) 2 - DL - 2 (7) 2 (10) 2 (12) 2 (10) 2- E L
The stomach is very long with well marked folds and without caecum (Fig.12A, B). The narrow primary intestinal loop contains a large foliated endocarp (Fig.12A,B), but no other endocarps exist on the internal side of the body wall. The anus has a plain or undulated rim. The gut is loosely attached to the body wall by strips of tissue. The polycarps are very numerous (Fig. 12A,B), 80 of them on the right side and 40 on the left were counted in a specimen 3cm in size. In shape of ampullae they are loosely attached to the body wall at proximal end. There is a ring of thin threads along the edge of the atrial velum.
All characters correspond to the detailed description given by Van der Sloot (1969) for P. cartilaginea whose distribution seems limited to the southern part of the Mexico Gulf from Panama (Collin et al 2005 without description), Colombia (type locality), Curaçao (Goodbody 1984) and Guadeloupe (Monniot C. 1983).

All specimens have a thick wrinkled tunic with abundant epibionts. The siphon apertures are hardly visible from outside. The body wall is easily extracted from the tunic; it is white opaque and thick with a pink ring at the siphon edge. Internally the siphons have a wide red velum. Some thread like papillae are found on the oral velum, but numerous pointed papillae cover the atrial velum (Fig.13B). The dorsal tubercle is particularly thick and protruding opening in a S (Fig.13A). The branchial sac has 4 folds on each side (Fig. 14) and transverse vessels in several orders of size, some very thick. The dermato-branchial bridges are also opaque and thick. There are no parastigmatic vessels. One branchial formula on the right side is:
Right E - 3 (19) 5 (20) 4 (24) 4 (25) 5 - DL left
The digestive tract occupies ½ of the left body side and is attached to the body wall (Fig.13C). The stomach wall is thick and opaque; it has no caecum. The primary loop is short, closed and contains a foliated endocarp. The rectum ends in a minutely lobed anus. The gonads are numerous, included into the body wall and slightly projecting at its surface (Fig. 13C). The polycarps are elongated, of irregular outline, often associated in a common envelope looking as ramified; they occupy the whole internal side of the body (Fig. 13C). Numerous endocarps are scattered between the polycarps.
This description is similar to that given by Van der Sloot (1969) and by Van Name (1945) for Polycarpa circumarata which is a junior synonym.

P. spongiabilis is a common ascidian of the Caribbean Sea and specimens from Madibenthos agree with the precise description given by Van der Sloot (1969) so only the main specific characters are given below. The specimen size varies from 1cm to 8cm. The tunic is thick but soft either covered with epibionts or sand and shells. The body wall is brownish in formalin with a dense musculature but the polycarps remain slightly visible from outside. The oral tentacles are numerous in 3 orders of size with brown pigment. There is a large oral velum (Fig. 15A,B) and a cloacal velum with an undulated edge wearing thread like papillae as figured in Van der Sloot (1969 fig. 63) and Monniot C. (1983 fig. 9B). The dorsal tubercle with more or less curved horns is located in a wide V of the prepharyngeal area devoid of papillae. The branchial sac is characteristic of the species (Fig. 15 A’, B’). There are 4 folds on each side, though in large individuals two or more longitudinal vessels just to the right of the dorsal lamina join posteriorly to make a partial 5th branchial fold (Fig. 15 A’, B’). The alimentary canal forms a closed loop situated posteriorly on the left body side. There is a small curved stomacal caecum (Fig; 15A). The anus has more or less low lobes. The primary gut loop contains one large foliated endocarp and two smaller ones (Fig. 15). The polycarps are oval and partly included into the body wall (Fig. 15A,B); sometimes they occupy the whole surface of the internal body wall. There are no endocarps at all on the body wall except those inside the gut loop. The geographic distribution of P. spongiabilis is restricted to the Caribbean Sea, Florida (Van Name 1945), Bermuda (Monniot C. 1972), Brazil (Rocha et al 2012).

A small sized and rather stout species with five-lobed head and a pair of ocellar granules. Hypostomium weakly developed. Adhesive tubes short, stocky and thick, ending in a notch. Anterior sensory bristles apparently absent, posterior sensory bristles anchored by double keeled scales. Dorsal scales are rhomboidal with rounded edges and increase in size towards the posterior end. Ventral interciliary field with a pair of spined terminal scales and 9–10 columns of keels; scales apparently not developed. Ventral ciliation in two longitudinal bands not merging on the head, however a short longitudinal band of ciliary rows is present behind the mouth. Pharynx slightly swollen at both ends. The Swedish specimen was in parthenogenetic phase and agrees well with literature data.
Previously recorded from Germany (Schwank 1990), Italy (Balsamo 1990), Poland (Kisielewski 1998), Russia (Tretjakova 1991) and Brazil (Kisielewski 1991).

The specimen of Aspidiophorus cf. oculifer agrees well with the description of A. oculifer above and data from the literature. However, the Swedish specimen disagrees with the description of A. oculifer in that it lacks a pair of ocellar granules. The lack of ocellar granules alone does not justify describing A. cf. oculifer as a new species. Ocellar granules have been reported to be either present or absent in different populations of the same species (e. g. Heterolepidoderma ocellatum) (Schwank 1990; Fregni et al. 1998).

A rather slim and elongated species with rounded to weakly three-lobed head. Cephalion well developed. One pair of cephalic ciliary tufts with one cilium considerably longer than the others. Two pairs of dorsal sensory bristles. The dorsal scales are longitudinal elliptical and keeled. The posteriormost scales are keeled but not pedunculated and larger than the others. Ventral interciliary field with a pair of large suboval keeled terminal scales and approximately 10 columns of keeled scales; their borders could not be seen. Ventral ciliation in two longitudinal bands that are further divided on the head, but not merging. Pharynx widens towards the pharyngeal intestinal junction. The Swedish specimens, all in parthenogentic phase with large eggs, fall within the ranges of literature data but are in general larger than most previously recorded specimens. The anteriormost part of the intestine has a granulated appearance, also recorded in Polish specimens (Kisielewski 1986).

A large sized species with five-lobed head. Hypostomium well developed as a transverse cuticular bar. The dorsal scales are rhomboidal in shape. Three pairs of simple straight spines are present dorsally at the base of each furcal branch. In the Swedish specimen the middle spine is the shortest, which is in contrast to Roszczak (1969) and Schwank (1990) but in accordance with Kisielewski (1986). Moreover, the number of dorsal scale columns is approximately 28, which is in contrast to Schwank (1990) who states that there are 12–15 dorsal columns. This may be explained by the extremely compressed state under which the Swedish specimen was recorded. However, the total number of columns (including ventrolateral) are 45 and in accordance with Polish specimens found by Kisielewski (1986). The posterior trunk region is covered by apparently non-pedunculated keeled scales. In the caudal bifurcation some of these scales can be seen to carry short spines, perhaps corresponding to the bristles reported by Kisielewski (1986). Ventral interciliary area covered by alternating rows of keels. Ventral ciliation in two longitudinal bands; whether they merge on the head could not be seen. Pharynx, with cuticular reinforcements (Figure 4 B), widens towards the pharyngeal intestinal junction.

A small sized species with weakly five-lobed head. Two pairs of sensory bristles; anterior pair anchored by papillae and posterior pair by double keeled scales. Dorsal scales are rhomboidal in shape with weakly rounded edges. Two pairs of characteristic simple spines are present in the posterior trunk region. Each spine of the longer anterior pair is 10–12 µm in length and anchored by a scale with keels on either side of the spine base. The shorter posterior pair reaches 5–6 µm in length and is anchored by smaller scales just at the base of the furca. Interciliary field with approximately 8 columns of keels which can be followed up at least halfway the length of the pharynx. Paired ventral terminal keeled scales that widens toward the distal end. Ventral ciliation in two longitudinal bands not merging on the head. Pharynx, broad with large terminal swellings, posterior swelling larger than anterior.

A relatively small sized species, with five-lobed head and a pair of ocellar granules. Sporadic absence of ocellar granules have been reported in some populations (Schwank 1990; Fregni et al. 1998). Two pairs of sensory bristles present, each of the posterior pair anchored by a double-keeled scale. Dorsal body surface covered by elongated elliptical keeled scales, smaller in size in head and neck regions. Interciliary area naked except for a pair of keeled terminal scales and 1–2 transverse rows of 3–4 keeled scales. Pharynx with small swellings at both ends.
Two of the Swedish specimens were in post-parthenogenetic phase with X-organ and sperm present (Figure 9 A). Another peculiarity is that several specimens had more or less well developed short ventrolateral spines. In one specimen, the area between the edges of the posterior lateral parts of the scale appeared to be depressed giving the appearance of a tri-lobed scale. The keels were not modified in this part but instead gave the impression of a short spine. Whether the keel was actually in contact with the depressed area could not be determined.
This species is widely distributed in Europe (see e. g. Greuter 1917; Mola 1932; Remane 1935 –36; Valkanov 1937; Rudescu 1967; Martin 1981; Schwank 1990; Kisielewski 1998) and is also reported from Canada (Schwank 1990), United States (Schwank 1990), Japan (Saito 1937) and Brazil (Kisielewski 1991).

Material. 8 specimens. TL, 242–309 µm; FL, 30–35 µm; PhL, 50–62 µm; MD, 9–12 µm; DC, 10–12 DR, 35– 36 VC, 6–8.
Long and slender species, with hammer-shaped, three- to five-lobed head, with large cephalion. Dorsal scales are elliptical to heart-shaped and partially overlapping. Three pairs of long rigid bifid spines and a single median bifid spine, all in posterior dorsal trunk region overshooting the furcal branches, are characteristic of the species. The other dorsal spines are simple or, especially in the posterior trunk region, have less well developed denticles. Interciliary area is covered by oval keeled scales carrying short simple spines, except for the terminal end which is covered by a couple of larger scales with longer spines. The Swedish specimens fall well within the ranges presented in the literature.
This species is widely distributed in Europe (see e. g. Grünspan 1908; Greuter 1917; Rudescu 1967; Martin 1981; Schwank 1990; Balsamo & Tongiorgi 1995; Kisielewski 1998) and is also reported from Japan (Sudzuki 1971), Korea (Lee & Chang 2000), Canada (Schwank 1990), Argentina (Grosso 1976) and Brazil (Kisielewski 1991).
