“…Although Isaac (1975) reported the distribution of the species C. longispinosum and C. rigidum to be worldwide, some authors consider that these are actually species-complexes, and that the strict forms have a more limited distributional range (Grygier 1994b, Suárez-Morales 2006. Dias and Bonecker (2007b) discussed the problem of the taxonomic complexes formed by the species C. cf.…”

During a series of zooplankton surveys carried out during 1984, off the south coast of the state of Rio Grande do Norte, Brazil, several species of monstrilloids were present in the samples. A total of 50 individuals of monstrilloid copepods were collected. These belong to four species (Monstrilla brasiliensis Suárez-Morales & Dias, Cymbasoma cf. longispinosum, Cymbasoma cf. rigidum, and Cymbasoma gracilis Gurney). The taxonomic complexes formed by the species C. cf. longispinosum and C. cf. rigidum in Brazilian waters are discussed. The lengths of the specimens are provided in order to contribute to studies and revisions of the specimens belonging to these species-complexes. The species Monstrilla brasiliensis is recorded for the first time in the Rio Grande do Norte coastal region, thus expanding its geographical range in the Brazilian northeastern coast. The results presented herein increase to four the number of species of Monstrilloida known from off Rio Grande do Norte state.

“…Since these syntypes originated from several localities, the type locality encompasses all of the places of origin (Article 73.2.3 of the Code). The specimen examined by Suárez-Morales (2006) may well be one of them. If this could be demonstrated more clearly, e.g.…”

This work seeks to expose and clear up nomenclatural irregularities involving copepods of the order Monstrilloida, family Monstrillidae. The diagnostic text related to Monstrilla minuta Isaac, 1974 and four nominal species of Thaumaleus Krøyer, 1849 (now Cymbasoma Thompson, 1888) proposed by Isaac in 1974 is sufficient for all names to be available from their original description except for Thaumaleus similirostratus, which was proposed conditionally in 1974 and was first made available by Isaac in 1975; “similirostris” as used by Grygier in 1995 is an incorrect subsequent spelling. Four other specific names proposed in 1975 by Isaac, but disclaimed by him as nomina nuda (an action permitted retroactively by the Fourth Edition of the International Code of Zoological Nomenclature) have never been made available. By quoting the necessary information from Isaac’s doctoral dissertation, two of them are validated herein under the names Thaumaleus frondipes Isaac in Grygier & Suárez-Morales, sp. nov., and Strilloma scotti Isaac in Grygier & Suárez-Morales, sp. nov., and are immediately reassigned as new combinations to Cymbasoma and Monstrilla Dana, 1849, respectively. A fifth such name, Thaumaleus tumorifrons, has already been made available under the authorship of Suárez-Morales, 1999, but its females are excluded from the type series; the spelling of the specific name of the new species recently proposed for those females, Cymbasoma mediterranea Suárez-Morales, Goruppi, Olazabal & Tirelli, 2017, is emended to mediterraneum to match the gender of the genus. For Cymbasoma bowmani Suárez-Morales & Gasca, 1998, the “Form B” female mentioned in the original description is excluded from the type series. The authorship and date of availability of Haemocera (currently Cymbasoma) morii depends on which language version of Article 13.1.1 of the Code is followed; a ruling by the International Commission on Zoological Nomenclature under Article 87 of the Code is necessary to resolve the matter. The composition of the type series of Cymbasoma bullatum (Scott, 1909) in terms of both number and sex has become unclear; its type locality is restricted herein to the vicinity of Obi Island in the Moluccas. Despite a published statement to the contrary, the syntype series of Cymbasoma germanicum (Timm, 1893) included specimens from other localities than just Helgoland. The type series of Cymbasoma guerrerense Suárez-Morales & Morales-Ramírez, 2009 consists only of the holotype, which was mistakenly reported under the wrong registration number. The supposed invalidity of Monstrilla capitellicola Hartman, 1961 is discussed. Monstrilla javensis Isaac, 1974, nomen nudum, has remained unavailable owing to lack of adherence to Article 16.1 of the Code by later authors; the specific name is made available herein, under Suárez-Morales’ authorship, in the combination Cymbasoma javense sp. nov. The taxonomic (and eventual nomenclatural) question of the status of M. mariaeugeniae Suárez-Morales & Islas-Landeros, 1993 vis à vis M. wandelii Stephensen, 1913, i.e. as a separate species or a subspecies of the latter, remains unsettled. Cymbasoma lenticula Suárez-Morales & McKinnon, 2014 and Monstrillopsis boonwurrungorum Suárez-Morales & McKinnon, 2014 are fixed herein as the correct original spellings of those two specific names. Resolution of the problem posed by assignment of the specific name reticulata to supposedly non-conspecific males and females in the genus Monstrillopsis Sars, 1921 requires the designation of a neotype by the International Commission on Zoological Nomenclature.

“…Although the genuine identity of Cymbasoma rigidum Thomson, 1888, which is likely to be a species complex with different morphotypes (see Suárez-Morales, 2006), has not been clearly conformed, C. striifrons n. sp. apparently differs from C. rigidum s.l.…”

A new monstrilloid species belonging to the genus Cymbasoma is described as a preliminary result from nocturnal surveys using a light trap on the east and south coasts of South Korea. Monstrilloid copepods are first recorded in South Korea. Cymbasoma striifrons n. sp. resembles C. striatum (Isaac, 1974) and C. tumorifrons Isaac, 1975 in sharing the character combination of transverse striations on forehead, somewhat small body (generally slightly less or longer than 1 mm), single lobed leg 5 bearing a short medial seta in female, and smooth lateral margin of anal somite without notch and wrinkles. However, C. striifrons n. sp. differs from C. striatum by relatively short and swollen cephalothorax, and rather strongly wrinkled genital somite. Cymbasoma striifrons n. sp. is also distinguished from C. tumorifrons in lacking a rounded protuberance on anterior margin of ventral surface and by relatively short cephalothorax and the number of ventral nipple-like processes on cephalothorax. Herein the new species is described and illustrated, with some comments on the morphological comparison with its allied species
