Tromikosoma koehleri Mortensen 1903
No full textTromikosoma koehleri Mortensen, 1903 Reports for the Azores: Tromikosoma cf. koehleri Mortensen, 1903 — $ Mironov 2008: 4, tab. 1; Tromikosoma koehleri Mortensen, 1903 — Mironov 2014: 122. Type locality: Davis Strait. See: Mortensen (1935: 167–168, fig. 100, pl. 5). Occurrence: North Atlantic, from the Davis Strait (Mortensen 1903) south to the Charlie-Gibbs Fracture Zone and north of the Azores (Mironov 2008). Depth: 2,517–3,527 m (AZO: 2,954–2,968 m; Mironov 2008). Habitat: probably a bottom-feeder living on soft sediments. Remarks: Tromikosoma koehleri was only known from its type locality. More recently, Mironov (2008) reported this species among the material collected by G.O. Sars (MAR–ECO expedition) in the Charles-Gibbs Fracture Zone. The same author listed material likely to belong to this rare species collected at stations located in the northern waters of the Azores (G.O. Sars, MAR–ECO cruise, sta 40/367: 42°55”N, 30°20”W, 2,954 –2,968 m). Later, however, Mironov (2014) placed the MAR-ECO ’ station from the Azores in the geographical distribution of this species. Mironov also added that this species is very closely related to T. uranus also known from the Atlantic (see below). Both species are known from very little material, and may prove to be identical.Published as part of Madeira, Patrícia, Kroh, Andreas, Cordeiro, Ricardo, De, António M., Martins, Frias & Ávila, Sérgio P., 2019, The Echinoderm Fauna of the Azores (NE Atlantic Ocean), pp. 1-231 in Zootaxa 4639 (1) on page 121, DOI: 10.11646/zootaxa.4639.1, http://zenodo.org/record/334216
Stereocidaris ingolfiana ? Mortensen 1903
No full textStereocidaris ingolfiana ? Mortensen, 1903 Reports for the Azores: Stereocidaris ingolfiana Mortensen, 1903 —? $ Pérès 1992: 254, 258. Type locality: Denmark Strait. See: Mortensen (1903: 38–41, pl. 6, figs. 1–5, pl. 8, figs. 4, 10–11, 16, 19–21, 23, 26, 28, 30, 36, pl. 11, figs. 12, 16–17, 23, 28, 30, 32–33; 1928: 267–268, pl. 27, figs. 1–3, pl. 70, fig. 6). Occurrence: North Atlantic, from the Denmark Strait south to the Caribbean in the west and to Cape Verde in the east (Mortensen 1928). Depth: 300– 1,745 m (Mortensen 1928);? AZO: 2,050 –3,300 m (Pérès 1992). Habitat: soft sediments (Koehler 1909). Larval stage: lecithotrophic (Emlet 1995). Remarks: Pérès (1992) claimed to have observed Stereocidaris ingolfiana during a dive made by the bathyscaphe Archimède north of S„o Miguel Island (2,050 m depth) and east of Santa Maria Island (3,150 –3,300 m depth). No specimen was collected and the identification seems to have rested solely on the long size of the spines of the observed animals. Pérès observations could represent an intermediary record between the east and West Atlantic populations, though S. ingolfiana known depth range is slightly shallower than the depth reported by this author. In the other hand, Cidaris cidaris is the only cidaroid confirmed species to occur in the archipelago with abundant documented material (see above). At macroscopic level these two species are almost identical, and in many instances the diagnose rests on the observation of pedicellaria (see Mortensen 1927a, 1928). Thus, until material belonging to S. ingolfiana is documented in the archipelago, Pérès observation must be placed as a dubious record (see also remarks under Histocidaris purpurata).Published as part of Madeira, Patrícia, Kroh, Andreas, Cordeiro, Ricardo, De, António M., Martins, Frias & Ávila, Sérgio P., 2019, The Echinoderm Fauna of the Azores (NE Atlantic Ocean), pp. 1-231 in Zootaxa 4639 (1) on page 98, DOI: 10.11646/zootaxa.4639.1, http://zenodo.org/record/334216

Microcyphus ceylanicus Mortensen 1942
No full textMicrocyphus ceylanicus Mortensen, 1942 Figure 2 Material studied. WUSL /ER/87 (dry, denuded) from Hiriketiya; WUSL /ER/234 (wet, with spines) from Hiriketiya; WUSL /ER/235 (dry, denuded) from Dickwella. Literature records for Sri Lanka. Mortensen (1942, 1943a), Price & Rowe (1996), Fernando (2006), Jayakody (2012). Distribution in Sri Lanka. Southern coast of Sri Lanka. Recorded depth range in Sri Lanka. 1–5 m (previous records). Habitat. Coral reefs (Price & Rowe 1996). Observed occurrence in this study. Southern coast (Hiriketiya and Dickwella), on shore. Both of these collection sites were dominated by seagrass beds at shallow depths. Remarks. Here, for the first time, we provide photographs of test surface details on this rarely seen temnopleurid (Fig. 2). Its test has never been figured in detail, and Mortensen (1943a) included only a photograph in lateral view, plus drawings of the apical system, ambulacral compounding, and some pedicellariae. M. ceylanicus is restricted to Sri Lanka and the Andaman Islands, and can be distinguished from other Sri Lankan regular echinoids by its light olive-green test. The test has naked interambulacral areas, each of which has a dark zigzag line along the medial sutures (Fig. 2). The spines are banded with red, brown, and white. This species is characterized by its sharply delimited naked areas in both the interambulacra and ambulacra (Mortensen 1942). Döderlein (1888) misidentified this species as M. maculatus, an error that was rectified by Mortensen (1943a). The type specimen, collected from Sri Lanka, is housed at the Zoologische Staatssammlung München (The Bavarian State Collection of Zoology, Munich).Published as part of Arachchige, Gayashan M., Jayakody, Sevvandi, Mooi, Rich & Kroh, Andreas, 2019, An annotated species list of regular echinoids from Sri Lanka with notes on some rarely seen temnopleurids, pp. 35-57 in Zootaxa 4571 (1) on page 42, DOI: 10.11646/zootaxa.4571.1.3, http://zenodo.org/record/260594

H.L. Clark (1918) suggested this specimen might represent a juvenile stage of <i>Ophiactis abyssicola</i>, a cosmopolitan deep-water species. Mortensen (1920, 1927) believed this specimen was actually <i>O. nidarosiensis</i>. Unfortunately, the specimen collected by <i>Princesse Alice</i> was lost (Mortensen 1920), and until new material is retrieved, the presence of either species in the archipelago should be considered as doubtful.</p>Published as part of <i>Madeira, Patrícia, Kroh, Andreas, Cordeiro, Ricardo, De, António M., Martins, Frias & Ávila, Sérgio P., 2019, The Echinoderm Fauna of the Azores (NE Atlantic Ocean), pp. 1-231 in Zootaxa 4639 (1)</i> on page 25, DOI: 10.11646/zootaxa.4639.1, <a href="http://zenodo.org/record/3342161">http://zenodo.org/record/3342161</a>
Luidia ciliaris Mortensen 1927

Type locality: Sicily, Mediterranean Sea. See: A.M. Clark (1982a); A.M. Clark & Downey (1992). Occurrence: Mediterranean Sea and Northeast Atlantic; from Scandinavia, the Faeroe Channel (Sneli 1999) south to Morocco (Mortensen 1925) and? Cape Verde (A.M. Clark (1982a), including the Azores, Madeira (D̂derlein 1920) and Canaries (Madsen 1950). Depth: 1–650(?805) m (A.M. Clark 1982a, Gage et al. 1983), typically from 25 to 200 m (Madsen 1950); AZO:?littoral. Habitat: hard to soft sediments, often found partly buried in gravel (Picton 1993). Larval stage: planktotrophic (Mortensen 1921). Remarks: the first record of Luidia ciliaris in the Azores can be trace back to D̂derlein’s (1920) review of the genus, which included a specimen collected in the archipelago from the Simroth collection, though the later author never included any material belonging to this species or genus in his 1888’s report. More recently, Wirtz (2009) reported an animal of Luidia ciliaris in a large tide-pool at Faial Island (not collected). The latter author claimed that a picture could be found in Wirtz & Debelius (2003), however, the photographed specimen in the 2003 work is from Madeira. The absence of documented specimens in the archipelago in over 80 years places the presence of this species in the Azores in a somewhat precarious position and thus, should be dealt with caution.Published as part of Madeira, Patrícia, Kroh, Andreas, Cordeiro, Ricardo, De, António M., Martins, Frias & Ávila, Sérgio P., 2019, The Echinoderm Fauna of the Azores (NE Atlantic Ocean), pp. 1-231 in Zootaxa 4639 (1) on page 80, DOI: 10.11646/zootaxa.4639.1, http://zenodo.org/record/334216
Fibulariella angulipora Mortensen 1948
No full textFibulariella angulipora Mortensen, 1948 Figures 34, 35 1948d Fibularia (Fibulariella) angulipora Mortensen: p. 6. 1948b Fibularia (Fibulariella) angulipora Mortensen. —Mortensen: p. 224–225; pl. 46: figs. 1–4, 12–14. Material studied. Ten denuded tests: WUSL/EI/132, EI/133, EI/144, EI/145, EI/146, EI/147, EI/148, EI/149, EI/ 150, and EI/151, from Etalai, Kalpitiya, Sri Lanka. Description. Shape and size —Test oval, rounded or pointed at both ends, small size, 3.39–7.14 mm TL, longer than broad, width 65–71% TL, height 43–53% TL; greatest height usually anterior to apical system; oral side convex; raised, rounded margin; aboral surface sloping slightly downward towards posterior end. Apical system —Subcentral, 41–51% TL from anterior margin; four small, circular gonopores, multiple small hydropores, not in groove, scattered over anterior portion of madreporic plate. Ambulacra —Petaloid area longer than half of TL, 66–71% TL; petaloid area width 40–46% TL; petals short, with 3–5 pore pairs in posterior paired petals, 3–4 pore pairs in anterior paired petals, 4–5 pore pairs in petal III; pores in posterior petals markedly triangular. Peristome —Medium-sized, 15–19% TL; usually rounded, width 13–17% TL; lies slightly anterior of centre, 40–47% TL from anterior margin. Periproct —Small, 8–9% TL; oval in outline, slightly elongate; situated closer to peristome than posterior edge, 17–23% TL from posterior margin. Geographic range. Indo-West Pacific, from Andaman Sea (Putchakarn & Sonchaeng 2004) to Gulf of Siam and the Molucca Sea (Mortensen 1948b). Bathymetric range. 15 m (Mortensen 1948b). Observed occurrence in Sri Lanka. The current study found only denuded tests of F. angulipora on the shore of Etalai, Kalpitiya, in north-western coasts of Sri Lanka (Fig. 35). Remarks. According to (Mortensen 1948b: 225), this species differs from the two other Fibulariella species, F. acuta and F. oblonga, by the large, triangular pores in the petals. F. angulipora is recorded here for the first time from Sri Lanka. This supports Mortensen's (1948b: 225) suggestion that the specimen mentioned as Fibularia volva by H. L Clark (1915) was in reality Fibulariella angulipora, not Fibularia volva.Published as part of Arachchige, Gayashan M., Jayakody, Sevvandi, Mooi, Rich & Kroh, Andreas, 2019, Taxonomy and distribution of irregular echinoids (Echinoidea: Irregularia) from Sri Lanka, pp. 1-100 in Zootaxa 4541 (1) on pages 41-44, DOI: 10.11646/zootaxa.4541.1.1, http://zenodo.org/record/261746
