03C5878AFFABFFE76171FF7AFD8CF97D.taxon	discussion	REMARKS Chicoreus (Triplex) kantori n. sp. can be separated immediately from all other Triplex species by having three narrow, very weakly frondose spines, extending from P 1, P 3 and P 5 on the axial varices, by the small weakly adapically curved spine extending from MP and by the strongly abaxially bent siphonal canal. Chicoreus (T.) crosnieri Houart, 1985 (Fig. 4 D-E) is comparatively larger with broader and higher intervariceal axial nodes, more strongly frondose and more numerous variceal spines, usually extending from P 1, P 3, P 5 and P 6, P 2 and P 4 being very narrow and only in very few specimens extending as very short, narrow variceal spines, otherwise spineless. The siphonal canal is straighter and bears a relatively long spine, extending from MP and a shorter one from ABP, both strongly bent abapically. Chicoreus (T.) zululandensis Houart, 1989 (Fig. 4 F) differs in having a relatively larger and more rounded protoconch and also in having more numerous variceal spines and a straighter siphonal canal with weakly curved, abapically bent spines: ADP, MP, ABP. Chicoreus (T.) boucheti Houart, 1983, C. (T.) paucifrondosus Houart, 1988 and C. (T.) subpalmatus Houart, 1988 from New Caledonia also have a strongly abaxially bent siphonal canal as observed in C. (T.) kantori n. sp. rather than the straight canal of other Triplex species, but they differ by many other shell characters and do not need to be compared further here.	en	Houart, Roland, Héros, Virginie (2013): Description of new Muricidae (Mollusca: Gastropoda) collected during the ATIMO VATAE expedition to Madagascar “ Deep South ”.

Zoosystema 35 (4): 503-523, DOI: 10.5252/z2013n4a5, URL: http://dx.doi.org/10.5252/z2013n4a5
03C5878AFFAFFFE562A3FAEEFFA5FAB9.taxon	discussion	REMARKS Naquetia and Chicomurex Arakawa, 1964 are two muricine genera with closely similar shell morphology, with an average height of 40 - 120 mm in Naquetia and 30 - 85 mm in Chicomurex. The protoconch is paucispiral, consisting of 1.5 - 2 whorls, or conical of sinusigera type, with 3 - 3.5 glossy whorls, usually with a narrow keel abapically. Each teleoconch whorl bears three rounded, squamous varices from the second or third whorl, with short, broadly open spines connected by squamous webbing. The radula is similar in the two genera, consisting of crowded rows of teeth with a rachidian bearing a large, broad, triangular central cusp (Houart 1992: figs 116 - 128) and Figure 8 A, B. The type species of Chicomurex, C. laciniatus (Sowerby, 1841) differs from the type species of Naquetia in having a broader and more globose shell, a comparatively lower spire and a proportionally larger and broader aperture. Within these two genera, all species consistently exhibit this distinction. The two genera are also distinct in a molecular phylogenetic analysis (Barco et al. 2010). The new species described here is included in Naquetia in spite of the slightly broader shell relative to its length compared to other Naquetia species and the relatively low spire. However, it differs from Chicomurex in having a short, broad, squamous siphonal canal, relatively shorter variceal spines and a more strongly triangular outline, which are typical characters of Naquetia.	en	Houart, Roland, Héros, Virginie (2013): Description of new Muricidae (Mollusca: Gastropoda) collected during the ATIMO VATAE expedition to Madagascar “ Deep South ”.

03C5878AFFAFFFEA6297FF9DFDFFFA58.taxon	discussion	REMARKS Three species of Naquetia are recorded from Madagascar or nearby areas: N. barclayi (Reeve, 1845), N. cumingii (A. Adams, 1853) and N. vokesae (Houart, 1986). Naquetia barclayi is very different and does not need to be compared here.	en	Houart, Roland, Héros, Virginie (2013): Description of new Muricidae (Mollusca: Gastropoda) collected during the ATIMO VATAE expedition to Madagascar “ Deep South ”.

03C5878AFFAFFFEA6297FF9DFDFFFA58.taxon	description	Naquetia cumingii is less squamous, reaching a larger size relative to the number of teleoconch whorls and chiefly differs in having a very different, smaller protoconch, consisting of 2 - 2.15 whorls with a strongly keeled first whorl. Naquetia vokesae (Fig. 4 K-M) differs in having a relatively narrower shell with a higher spire (height / width ratio 2.1 - 2.3 vs 1.9 - 2.0 in N. manwaii n. sp.), a protoconch only a third of the size, the penultimate and last teleoconch whorls with three or four narrow intervariceal, axial ridges vs two or rarely three elongate, broad knobs in N. manwaii n. sp., and in having a narrower aperture. Due to the similar-looking shells, two species of Chicomurex are here also compared: C. turschi (Houart, 1981) and C. rosadoi Houart, 1999, from Zululand (South Africa) and Mozambique, respectively. The record of C. turschi from Madagascar in Houart (1992: 123, fig. 433) has not been confirmed by additional material. The specimens illustrated by Merle et al. (2011: pl. 78, figs 13 a, b, 14) as C. turschi from southern Madagascar are most probably specimens of N. vokesae. Chicomurex turschi (Fig. 4 N, O) differs from N. manwaii n. sp. in having a taller, more slender spire with narrower teleoconch whorls, a comparatively smaller aperture, a more slender, longer siphonal canal and a smaller protoconch, less than half the size of N. manwaii n. sp. Chicomurex rosadoi, described from southern Mozambique, has a broader, more globose protoconch, probably denoting intracapsular larval development, broader spire whorls, a broader, globose last whorl, and a narrower siphonal canal.	en	Houart, Roland, Héros, Virginie (2013): Description of new Muricidae (Mollusca: Gastropoda) collected during the ATIMO VATAE expedition to Madagascar “ Deep South ”.

03C5878AFFA3FFEF62A7FE19FC15FC35.taxon	description	Favartia (F.) brevicula (Fig. 5 M, N), a species occurring throughout the Indo-West Pacific, differs in having a comparatively larger, broader shell with more strongly shouldered teleoconch whorls, a less sloping shoulder ramp, higher varices and a more rounded aperture. Favartia (F.) confusa (Fig. 6 A) from Queensland, Australia, differs in having a comparatively larger shell with more squamous varices, a less sloping shoulder ramp, relatively narrower spiral primary cords and a longer siphonal canal with the variceal wings almost extending to its tip. Favartia (F.) eastorum (Fig. 5 L) was described from Peak Island, Western Australia, and has not more recorded since. It resembles the new species but is distinctive in having a slightly higher and narrower shell with a less sloping shoulder ramp, a comparatively narrower aperture, a broader siphonal canal and slightly higher and narrower varices. The holotype is not the best specimen but it has been chosen as the name-bearing type because it is associated with a molecular sequence.	en	Houart, Roland, Héros, Virginie (2013): Description of new Muricidae (Mollusca: Gastropoda) collected during the ATIMO VATAE expedition to Madagascar “ Deep South ”.

03C5878AFFA5FFED62D8FE58FAA8FC92.taxon	discussion	REMARKS Three Pygmaepterys species are known from the studied area or nearby localities: F. (P.) alfredensis (Bartsch, 1915), the type species, from Port Alfred, South Africa, F. (P.) isabelae Houart & Rosado, 2008 from Madagascar and Mozambique and F. (P.) maraisi (Vokes, 1978) from northernTranskei, South Africa. None of these species has a shell with three axial varices on the penultimate and last teleoconch whorls and they do not need to be compared here. F. (P.) alfredensis and F. (P.) isabelae have five narrow varices while F. (P.) maraisi has six to eight varices on the last teleoconch whorl.	en	Houart, Roland, Héros, Virginie (2013): Description of new Muricidae (Mollusca: Gastropoda) collected during the ATIMO VATAE expedition to Madagascar “ Deep South ”.

03C5878AFFA5FFED62D8FE58FAA8FC92.taxon	description	The Pygmaepterys species with three varices on the last teleoconch whorl are F. (P.) cracentis (Houart, 1996) from Indonesia, F. (P.) dondani (Kosuge, 1984) from the Philippines and F. (P.) menoui (Houart, 1990) from New Caledonia. Favartia (P.) dondani is a very different, larger species and does not need to be compared here. Favartia (Pygmaepterys) cracentis (Fig. 6 F) has a much narrower shell with more numerous axial varices on spire whorls: first and second whorl with seven ribs, third with six, penultimate with four or five and only the last whorl has three varices. The primary and secondary spiral cords are also more numerous than in F. (P.) fournierae n. sp. and more regularly shaped with primary and secondary cords of almost similar size, with a total of 11 or 12 cords on the last teleoconch whorl. Favartia (Pygmaepterys) menoui (Fig. 6 G, H) is the most similar species, but it differs in having three varices only from the fourth teleoconch whorl instead of the second or third in F. (P.) fournierae n. sp., in having a different spiral sculpture morphology with broadly spaced P 1 and P 2 with an additional s 1 between them, followed by a broad P 3 and narrower P 4, then s 4, P 5, P 6, MP and ADP, and in having a comparatively smaller and narrower aperture. The spiral cord morphology in F. (P.) fournierae n. sp., particularly the higher and broader second spiral cord (P 2) as well as the axial, flattened growth lamellae or scales are reminiscent of Pterynotus concavopterus Kosuge, 1980 from the Philippines, a species that was doubtfully included in Timbellus de Gregorio, 1885 by Merle et al. (2011). The similarities between P. concavopterus and F. (P.) fournierae n. sp. and other Pygmaepterys species are intriguing. The shell morphology of P. concavopterus is certainly more similar to muricopsine species than to any Pterynotus Swainson, 1833 or Timbellus species. Molecular analyses and study of the radula are needed to confirm the probable new classification of this species, till now only known from the Philippines.	en	Houart, Roland, Héros, Virginie (2013): Description of new Muricidae (Mollusca: Gastropoda) collected during the ATIMO VATAE expedition to Madagascar “ Deep South ”.

Crossing of axial ribs and primary spiral cords giving rise to broad, moderately high nodes. Crossing of axial growth lamellae with secondary cords and threads giving a reticulate appearance to the shell. Aperture moderately large, ovate. Columellar lip narrow, with two elongate, weak, oblique folds centrally, rim completely adherent, broadly expanded abapically. Occasionally with weak parietal tooth at adapical extremity. Anal notch deep, narrow. Outer lip weakly erect, thin, with weak or very weak, elongate denticles within: D 1 split, D 2 split, D 3, D 4, D 5 (Fig. 6 N). Denticles increasing in strength up to D 4; D 5 very shallow, almost indistinguishable. Siphonal canal very short, broad, straight, broadly open.

03C5878AFFA7FFF06175FC3CFA20FC15.taxon	discussion	REMARKS The new species described here is included in Semiricinula because of the similar radular and operculum morphologies but also because of identical shell morphologies, especially the squamous shell structure, the typical, deep anal notch, and the two narrow columellar folds. The radula of S. turbinoides is illustrated (Fig. 8 F) to show the similarities between the two species. Semiricinula bozzettii n. sp. differs from S. turbinoides (Fig. 7 E) in having a lighter, more delicate shell with more numerous axial ribs, nine or ten on penultimate and last whorls vs seven in S. turbinoides, much narrower primary spiral cords, split apertural denticles and chiefly, in having a very different protoconch of 1.75 rounded whorls (Fig. 7 K, L) vs 2.5 - 3 whorls with a duplicate narrow keel on the last whorl in S. turbinoides. The protoconch also lacks a sinusigeral notch (Fig. 7 M). The status of Thais tricolorata Bozzetti, 2010 will be discussed in an upcoming paper in progress. However, S. bozzettii n. sp. differs from T. tricolorata in the same ways that it differs from S. turbinoides. Semiricinula bozzettii n. sp. can also be compared with S. muricoides (Blainville, 1832) (Fig. 7 C, D), which has not been recorded from Madagascar and which also has a paucispiral protoconch of 1.75 to 2 rounded whorls. However, S. bozzettii n. sp. differs from S. muricoides in having a smaller, more delicate shell with much narrower primary spiral cords, a narrower anal notch, split apertural denticles and more numerous axial ribs. Because of its reticulate shell morphology, Semiricinula bozzettii n. sp. could also be considered as a Phycothais Tan, 2003 species. Phycothais was originally described by Tan (2003: 956) to include two intertidal Australian species: P. reticulata (Quoy & Gaimard, 1832), which occurs from New South Wales to Western Australia, including Tasmania, and P. botanica (Hedley, 1918), known from Queensland to Tasmania. The shells are small, less than 20 mm in length with a paucispiral protoconch and a typical rapanine radula. A third species of Phycothais, P. texturata (E. A. Smith, 1904) was recently recorded by Houart et al. (2011). The shells also have a typical reticulate or cancellate sculpture due to the numerous axial growth lamellae, more obvious between than on the spiral cords. Semiricinula bozzettii n. sp. is similar to P. reticulata (Fig. 7 B) but differs in having a slightly narrower shell with a relatively higher spire, a different, narrower and deeper anal notch, a more obvious parietal tooth, and a folded columella, which is smooth in P. reticulata. It differs also from P. botanica (Fig. 7 A) in having a higher spire, a slightly less shouldered shell, a different, narrower and deeper anal notch, a folded columellar lip and also in having somewhat narrower primary spiral cords. Finally, Semiricinula bozzettii n. sp. differs in shell characters from P. texturata in the same way that it differs from P. reticulata but also in having secondary and tertiary cords of similar strength in P. texturata vs of different strength in S. bozzettii n. sp. The holotype is not the best specimen, but it has been chosen as the name-bearing type because it is associated with a molecular sequence	en	Houart, Roland, Héros, Virginie (2013): Description of new Muricidae (Mollusca: Gastropoda) collected during the ATIMO VATAE expedition to Madagascar “ Deep South ”.
