“…It superficially resembles H. pusilla (Ritchie, 1910) (see Galea & Ferry 2015 for taxonomical considerations) through the shape of its internodes and hydrothecae. However, Ritchie's species is comparatively smaller (Galea 2010: table 3) and the perisarc of its hydrothecae is smooth throughout.…”

Two new genera and nine new species of hydroids are described based on deep-water material collected from off New Caledonia during various expeditions of the French Tropical Deep-Sea Benthos program. Caledoniana gen. nov., provisionally included in the family Sertulariidae Lamouroux, 1812, presently comprises three new species, viz. C. alata sp. nov., C. decussata sp. nov., and C. microgona sp. nov., while an additional group of three new species, is accommodated in the new sertulariid genus Solenoscyphus gen. nov.: S. candelabrum sp. nov., S. decidualis sp. nov., and S. striatus sp. nov. Furthermore, three new species of Hincksella Billard, 1918 (family Syntheciidae Marktanner-Turneretscher, 1890) are described, namely H. cornuta sp. nov., H. neocaledonica sp. nov., and H. similis sp. nov.

“…Sertularella areyi is a small but striking species, with barrel-shaped hydrothecae encircled by two prominent circular (not spiral) flanges (Vervoort & Watson 2003). Its gonothecae resemble Chinese lanterns, with about 7-10 transverse flanges (Vervoort 1993;Hirohito 1995;Galea 2016). Detailed accounts of this hydroid, based on colonies from the western Pacific Ocean, have been provided by Vervoort (1993) and Vervoort & Watson (2003).…”

“…Allman's type of S. diaphana was from Queensland, Australia. With the species now known to be widespread across the Indo-Pacific (Billard 1925b;Millard 1975;Gibbons & Ryland 1989;Vervoort 1993;Hirohito 1995;Vervoort & Watson 2003;Schuchert 2003;Di Camillo et al 2008;Galea 2016), its occurrence in Hawaii was to be expected. This hydroid has also been reported frequently in warm parts of the Atlantic as well (Calder 2019).…”

“…Tonga Islands (Kingdom of Tonga) (Stechow 1919 Remarks. The hydroid of Bicaularia tongensis (Stechow, 1919) is distinctive in having two opercular flaps, each one pleated along its median line, together with branches and gonothecae (when present) that arise from within the cavities of hydrothecae borne on the hydrocaulus (Galea 2010(Galea , 2016Song et al 2019). Uncertainty has existed in the past over generic affinities of this diminutive species, and it has been variously assigned to Sertularia Lin-naeus, 1758, Sertularella Gray, 1848, and Symplectoscyphus Marktanner-Turneretscher, 1890.…”

Some leptothecate hydroids (Cnidaria, Hydrozoa) from Hawaii, mostly from inshore and nearshore waters

This report is based on a small collection of hydroids from the Hawaiian Islands, in the central Pacific Ocean. Most of the examined material was obtained by staff of the Bernice Pauahi Bishop Museum, Honolulu, during surveys for nonindigenous marine species in shallow, sheltered, inshore or nearshore waters, and especially in harbours, bays, and lagoons. In all, 34 species of leptothecate hydroids, assigned to 14 families and 20 genera, were identified and are discussed. One of them, based on a single infertile colony with a damaged hydrotheca, was identified provisionally only to the rank of suborder. Given the limited geographic and bathymetric focus of the surveys, only four of the species, Clytia thornelyi, Halecium sibogae, Macrorhynchia balei, and M. hawaiensis, were collected at depths greater than 25 m. Seven species, Cirrholovenia tetranema Kramp, 1959, Orthopyxis crenata (Hartlaub, 1901), Clytia elongata Marktanner-Turneretscher, 1890, C. paulensis (Vanhöffen, 1910), Tridentata maldivensis (Borradaile, 1905), Monotheca flexuosa (Bale, 1894), and a hydroid identified only as Eirenida (undetermined), are recorded from Hawaii for the first time. Three others, Lytocarpia nigra (Nutting, 1905) Macrorhynchia balei (Nutting, 1905), and M. hawaiensis (Nutting, 1905), have their type localities in Hawaii, with the last of these being known to date only from the Hawaiian archipelago. Most of the species are well-known from shallow water areas across the tropical and subtropical Indo-Pacific region, and over half of them have been reported as well from warm waters in the Atlantic Ocean. Their existence in the remote islands of Hawaii is attributed to long-range dispersal by both natural and human-mediated means, including shipping.

“…To the north, Ralpharia multitentaculata (Fraser, 1938a) is known from the coast of Baja California, Mexico ). Across the Isthmus of Panama, Ralpharia gorgoniae Petersen, 1990 occurs on the Atlantic coast of Panama (Calder & Kirkendale 2005) and is widely distributed elsewhere in the Caribbean region (e.g., Galea 2013, Galea & Ferry 2015. Representatives of the genus occur essentially worldwide in warm seas.…”

An account is given of the names of families, genera, and species of hydroids established by C.M. Fraser of Canada, excluding those from Allan Hancock Pacific Expeditions and the Allan Hancock Caribbean Sea Expedition. The names of four families, 11 genera, and 101 species are attributed to him in this work, complementing those of another two genera and 164 species described by Fraser in various Allan Hancock publications. Information is provided on type localities of his new species, on locations and kinds of type material in existence, where known, and on the current taxonomic status of families, genera, and species described by him in works reviewed herein. Two replacement names (Thuiaria geniculata Fraser, 1918a and Salacia fraseri Calder, 1991) exist for Thuiaria distans Fraser, 1914a (not Thuiaria distans Allman, 1877). The widely overlooked senior synonym, T. geniculata, is recognized as the valid name of the species. Diphasia alta nom. nov. is proposed as a new replacement name for the permanently invalid junior primary homonym Diphasia robusta Fraser, 1943a (not D. attenuata robusta Billard, 1924). In addition, Cryptolaria crassa nom. nov. is proposed as a new replacement name for the junior secondary homonym Cryptolaria rigida (Fraser, 1948) [not C. rigida (Fraser, 1940a)]. Lectotypes have been designated for 47 of the species to establish objective standards for application of their names. Corymorpha adventitia Fraser, 1941b, from the Pacific coast of Panama, is assigned to Ralpharia Watson, 1980, as R. adventitia. No type specimens are known to exist for seven of the species considered, including one holotype (of Hebella eximia Fraser, 1944a) missing from its bottle. Particular attention has been paid to dating and chronology of the 51 publications of Fraser covered in this work. Earlier bibliographic errors are corrected, most notably establishing that the book Distribution and relationship in American hydroids was published in early 1947 rather than 1946 as per the title page.
