... According to Thandar (1992), his material from southern Africa described as M. parva differed from the descriptions of those given by some other authors [notably Théel (1886a) and Fisher (1907)] in that there is no marked difference in size between the ventro-lateral tube feet and those from elsewhere on the body. However, the body wall ossicles are similar to those illustrated by the above authors. ...
... According to Théel's (1886a) description the smaller tables are commoner, whereas Fisher (1907) stated that the latter are found only in the tube feet. In the southern African material, Thandar (1992) reported that both types occur in the body wall and only the smaller ones in the tube feet. The spire is also higher in the local material. ...
Suricata 9: A taxonomic monograph of the sea cucumbers of southern Africa (Echinodermata: Holothuroidea)
A.S. Thandar (2022)
The southern African marine region, which lies in the transitional zone between the Atlantic and Indo-Pacific biomes, has a very rich biodiversity with elements from the two major oceanic regions. This taxonomic monograph, long awaited by local enthusiasts, marine biologists and holothuroid specialists worldwide, focuses on the southern African Holothuroidea. It is based on the author’s approximately 55 years of research on the taxonomy of sea cucumbers with specific emphasis on the southern African fauna.
The monograph includes a brief account of the materials used; fixation, preservation and other techniques; an illustrated account of gross morphological features of mostly the shallow-water holothuroids; an illustrated glossary of the microscopic ossicles; some zoogeographical considerations; an updated checklist that summarises the composition, biodiversity and faunistic components of all southern African holothuroids; a dichotomous key to orders, families, genera and species; and the systematic account of all recorded species. All seven currently recognised orders are represented, distributed over 26 families, 76 genera and 171 nominal and 10 indeterminate species. These include a couple of new records for the southern African region. South Africa has 152 nominal species.
Each species account has a selected synonymy indicating the most pertinent synonyms, a brief diagnosis, the type locality, habitat notes, distribution data, concise remarks, a figure of the most important diagnostic characters and a distribution map. A comprehensive index and a full list of references that are cited or used in the text are also provided.

Collections of holothuroid echinoderms received from the Natal and South African Museums, the Universities of Cape
Town and Witwatersrand and that present in the former University of Durban-Westville, contain several new species and
many others that are new to the fauna of southern Africa, south of the tropic of Capricorn. A paper describing and/or
recording several dendrochirotids and a dactylochirotid, from a portion of these materials originating from the east coast
of southern Africa, has already been published. The current paper describes and/or reports on several new species and
records of aspidochirotid, molpadid and apodid holothuroids, also from the east coast, extending from Inhaca Island, off
the coast of Maputo (Mozambique), to the Port St. Johns-East London area (South Africa), the subtropical zoogeographic
province. A few other species have been included if they represent juvenile material, or considered extensions of ranges
(bathymetric or otherwise) of previously known species, or confirmation of a species previously recorded from a single
locality in the region under consideration, or for the provision of taxonomic data that was excluded for some previous
published records. Of the 30 species treated, four are new to science and seven are new records for the southern African
region. The new species are Holothuria (Lessonothuria) tuberculata, H. (Theelothuria) duoturriforma, H.(T.) longicosta
and H. (T.) pseudonotablis, whereas the new records include Stichopus cf. monotuberculatus (Quoy & Gaimard), Actinopyga
bannwarthi Panning, A. lecanora (Jaeger), Bohadschia marmorata (Jaeger), H. (Vaneyothuria) integra Koehler
& Vaney, Molpadia triforia (Cherbonnier) and Protankyra autopista (Marenzeller).
... Thandar' s revision was never published in its entirety but numerous papers resulted from this revision as well as from his and his co-workers' later works. The taxonomic ones of these mostly revise several families pertinent to southern Africa, south of the Tropic of Capricorn, describe new taxa or new records, or report on deep-sea collections (see Thandar 1977, 1985, 1986, 1987a& b, 1989a, b & c, Thandar & Rowe 1989, Thandar 1990, 1991, 1992, 1994, 1996, 1998, Rajpal & Thandar 1998, 1999, Thandar 1999, Thandar 2001, Thandar & Moodley 2003, Samyn & Thandar 2003, Massin et al. 2004, Thandar 2005. These additions still await a monographic treatment, which can only be completed once several unidentified collections, currently in the hands of the author, have been studied and recorded. ...
Numerous unidentified specimens of Holothuroidea received from the Natal and South African Museums or present in the collections of the former University of Durban-Westville, contain several new species and many that are new to the fauna of South Africa. This paper includes descriptions of new species or new records of several dendrochirotid holothuroids and a dactylochirotid from off the east coast of South Africa, extending from Kosi Bay in the north to the Port St Johns-East London area, in the Eastern Cape Province, the latter region represents the transition zone between the southern African subtropical and warm-temperate zoogeographical provinces. A few other species have been added if they represent juvenile material, or considered extensions of ranges (bathymetric or otherwise) of previously known species, or confirmation of a species previously recorded from a single locality in the region under consideration. Of the 16 species here treated, four are new to science, seven new to the fauna of South Africa, whereas the rest are either extension of ranges or additional records. The four new species are Psolidium multipes, P. acorbula, Ekkentropelma groovia and Psolidothuria yasmeena. The following six species are additions to the fauna of South Africa: Thyone avenusta Cherbonnier, 1970; T. comata Cherbonnier, 1988; Selenkiella paradoxa Cherbonnier, 1970; Ohshimella ocula (Cherbonnier, 1988); Plesiocolochirus tessellarus (Cherbonnier, 1970) and Staurothyone rosacea (Semper, 1869). Pseudocolochirus dispar (Lampert, 1889) is new to the fauna of southern Africa, recorded for the first time from Mozambique. The remaining species include Stolus pseudoalbescens Thandar, 2005; Sclerothyone velligera (Ludwig & Heding, 1935); Ohshimella ehrenbergii (Selenka, 1868); Pawsonellus africanus Thandar, 1986 and Trachasina crucifera (Semper, 1869).
... Fortunately, the nearby bathyal fauna of the eastern and southern shores of South Africa are better prospected. H.L. Clark (1923), Ludwig & Heding (1935), Cherbonnier (1952) and more recently A.M. Clark (1977), Solis-Marin (2005) and Thandar (1992;2006;2007;2007;2009) provided records. This paper provides detailed descriptions of the holothuroids we recognize as new to science and gives annotated taxonomic accounts of the other species sampled by the Miriky. ...
The 2009 expedition with the research vessel Miriky sampled the sublittoral and bathyal waters of the northern Mozambique Channel. This exploration campaign resulted in a small, but very diverse collection of holothuroids comprising 174 specimens representing 31 species, 18 genera, 10 families and 5 orders. Of these species, many were hitherto unknown for Madagascar or even for the Indian Ocean, and six, Bathyplotes aymeric sp. nov., Holothuria (Cystipus) yann sp. nov., Holothuria (Stauropora) bo sp. nov., Holothuria (Metriatyla) alex sp. nov., Holothuria (Theelothuria) cyrielle sp.nov., Molpadia thandari sp. nov., are new to science. Molpadia lenticulum (Cherbonnier & Féral, 1981) is a new combination. This contribution provides an illustrated and annotated overview of the poorly known, highly biodiverse, sublittoral and bathyal sea cucumber fauna of the northern Mozambique Channel. Our findings demonstrate how ignorant we are about the poorly explored habitats of our planet and therefore stress the urgent need for more explorations to such regions.

Holothurians are among the most species-rich taxa in the megabenthos on the northern Mid-Atlantic Ridge at depths of 2200–3700 m. Extensive new collections of 32 holothurian species were made in 2007–2010 in the Charlie Gibbs Fracture Zone area as part of the ECOMAR project. New material includes samples taken using a trawl and the ROV Isis. Samples and in situ observations from the ROV were of particular value because the morphological details of a number of holothurian species could be clarified. Many of these species are gelatinous and fragile and were damaged in trawls. Three species of elasipodid holothurians are described as new to science. An annotated check-list of all species of deep-sea holothurians collected in the Charlie Gibbs Fracture Zone area is provided. The checklist includes synonyms, distribution data and morphological descriptions as well as photographs taken in situ and in vivo. Ecological remarks are given for some species.
Fifteen species of deep-sea holothuroids were recorded from the South Java Deep-Sea (SJADES) Biodiversity Expedition 2018 from depths between 100-1,700 m. Of these, the following five species are new records for Indonesian waters: Zygothuria oxysclera (R. Perrier, 1899); Bathyplotes natans (M. Sars, 1868); Paelopatides gelatinosus (Walsh, 1891); Benthothuria funebris R. Perrier, 1898; and Pelagothuria natatrix Ludwig, 1893. Most of the 15 species were only observed from a single station, but several were found at two or more stations. The following five elasipodid sea cucumbers are described in detail here:
A miscellaneous collection of mostly small holothuroids, comprising some 140 specimens, received from the Iziko South African Museum (SAM), are here recorded and/or briefly described. Of these, one jar contained a badly mutilated holothuroid which was unidentifiable and hence not included here. The remaining material comprises 18 nominal species and an indeterminate elasipodid, perhaps representing a species of Benthodytes. Of the 18 nominal species, four are new to science, one of which has already been described as Trachythyone flaccida Thandar, 2013. Another, although represented by a single mature specimen from deep-water off the Transkei coast (Eastern Cape Province), is so different from its congeners that it is also described as a new species, Stereoderma mohammedi n. sp. Two other specimens, although juvenile, are so extraordinary in their composition of ossicles, that they are also taken to represent another new species, ?Temparena trouspetita n. sp. The collection also includes a single specimen of Synallactes, which together with a specimen misidentified as S. viridilimus by Thandar (2008), is also described as a new species, S. quatrami n. sp. The remaining species proved to be either new records for the southern African region or already well-known southern African forms whose distribution ranges have now changed.
You can find a list of species composition of thyroidtentaculate sea cucumbers of Aspidochirotida order in the Far-Eastern seas of Russia. Every species is accompanied by modern name, synonymy, information about dis-tribution in the Bering, Okotsk, Japan seas, at south-east Kamchatka and Kuril Islands. Part of the species is illu-strated with original pics of external structure. New location for Pseudostichopuspapillatus in the area of Kuril Islands at the depths of 182-186 meters is stated. Before in the Far East seas it was recorded only at south-east Kamchatka, near c. Shipunsky at the depths of 4100–4200 meters.
