03C187B8FFEEFFEFFF072E631BB001CD.taxon	discussion	Remarks. Recently, muricids have been typically classified into 12 subfamilies (e. g.: Houart 2018; Merle et al. 2022), integrating information from molecular phylogenetics (Barco et al. 2010, 2012) and anatomical and shell characters. However, the most recent molecular phylogenetic analysis (Russini et al. 2023), provided strong evidence to restrict the concept of the subfamily Muricinae s. s. to the clade including the type genus (Murex) and related taxa (Bolinus, Chicomurex, Chicoreus, Haustellum, Hexaplex, Muricanthus, Naquetia, Phyllonotus, Siratus, Vokesimurex), thus excluding from the subfamily the genera Timbellus, Flexopteron, Ponderia, and Pterynotus as in part already suggested by Barco et al. (2010) and Merle et al. (2011).

03C187B8FFEAFFF5FF072B2618730081.taxon	discussion	Remarks. Similar to the case of Chicoreus brunneus, none of the type specimens examined for C. microphyllus and its synonyms has a preserved protoconch. For the sake of stability and in accordance with previous authors (Radwin & D'Attilio, 1976; Houart, 1992; Merle et al. 2011), we restrict the concept of Chicoreus microphyllus to the lineage with paucispiral protoconch, and keep the two synonyms Chicoreus poirieri Jousseaume, 1881 and Murex jousseaumei Poirier, 1883, within the same concept.	en	Houart, Roland, Russini, Valeria, Fassio, Giulia, Oliverio, Marco (2025): Developmental types and a new cryptic species of Chicoreus (Gastropoda: Muricidae) from Papua New Guinea.

03C187B8FFF4FFF7FF072C571E5106ED.taxon	discussion	Remarks. Chicoreus phyrtos sp. nov. is morphologically indistinguishable from C. microphyllus (Fig. 5 A, F – R) except in having a 2.50 – 2.75 whorls conical protoconch with a sinusigeral notch, indicating a planktotrophic larval phase vs C. microphyllus with 1.75 – 2.5 rounded protoconch whorls indicating a lecithotrophic larval development. A shell with broken or strongly eroded protoconch cannot be correctly identified using any other morphological character of the shell. The protoconch of Chicoreus phyrtos sp. nov. is similar to that of C. torrefactus (G. B. Sowerby II, 1841) (Fig. 5 C) once considered a synonym of C. microphyllus (e. g. Radwin & D'Attilio 1976: 39). However, C. torrefactus is clearly different molecularly, and differs morphologically from both C. phyrtos sp. nov. and C. microphyllus in having a broader last teleoconch whorl, a columellar lip with a usually smooth or smoother outer edge and a characteristic notch at abapical extremity of that lip (Fig. 5 B), a feature already noted by Houart (1984: 57, text fig. 4) to separate C. torrefactus from C. dovi Houart, 1984. Both C. phyrtos and C. microphyllus lack this distinctive notch (Fig. 5 A).	en	Houart, Roland, Russini, Valeria, Fassio, Giulia, Oliverio, Marco (2025): Developmental types and a new cryptic species of Chicoreus (Gastropoda: Muricidae) from Papua New Guinea.
