FC5087EAFFAEFFF3FF6435C015E57811.taxon	discussion	Remarks. Cooper (1981) described Thecidellina minuta from Samper Bank, south-east of Madagascar mainly on the basis of its small size, as the name implies. Hoffmann and Lüter (2010) included this species in their new genus Minutella for small thecidellinids with a pseudodeltidium (renamed rugideltidium by Logan and Baker 2013). The latter feature was not described by Cooper but its presence in the type specimens was confirmed by Hoffmann and Lüter (2010). These authors described M. tristani and M. bruntoni from the Caribbean and also recognized an Indo-Pacific group (or clade) consisting of M. minuta from Samper Bank, T. minuta from New Caledonia (Bitner 2009, 2010), and M. cf. minuta from Okinawa, Fiji, and Lizard Island (Australia). To this list can be added Minutella cf. minuta from Sulawesi, Indonesia (Simon and Hoffmann 2013) and the Red Sea occurrences described here, as well as additional discoveries of this form from Palau and Saipan (our unpublished observations). This revised Indo-Pacific group is shown in Fig. 3 as localities M 1 – 9 and represents varieties of M. minuta with only minor differences insufficient to separate them as distinct species. The Red Sea specimens thus become the westernmost occurrence of a postulated Minutella minuta species complex stretching from the Red Sea to the central Pacific. According to Hoffmann and Lüter (2010, p. 158, pl. 3) one of the main distinguishing characters separating the 2 groups is the nature of the dorsal valve median septum which is narrow and straight in the Indo-Pacific group, but broad and heavily tapering posteriorly in the Caribbean group. However, Red Sea specimens demonstrate that this feature can be quite variable (compare figures 2 F, I, and L) and should be used with caution. Another difference is the presence in M. bruntoni and M. tristani of prominent median adductor muscle scars below the brachial bridge which are not seen in M. minuta. Although there are 28 specimens of M. minuta from Red Sea sediments they are all devoid of soft parts. The living sites have not been found, although it is presumed that they are from cryptic habitats in nearby reefal environments (Zuschin and Mayrhofer 2009), perhaps similar to those for Minutella bruntoni from Grand Cayman which, with Thecidellina barretti (Davidson) and Argyrotheca woodwardiana (Davidson), is common in low-light areas of reef caves (Logan 1983 a). The Red Sea specimens often show abrasion or damage to the shell, suggesting post-mortem transportation from their living sites. The species has only been found at 2 localities (SM 9 B and GZ 93 / 8) but its small size may have caused it to be overlooked elsewhere.	en	Logan, Alan, Bitner, Maria Aleksandra (2013): New records of Recent Brachiopoda from the Red Sea with a description of a new species.

FC5087EAFFA9FFF1FF6437E014667909.taxon	description	Description. Shell small for genus, length of ventral valve rarely exceeding 4 mm, width about 3.5 mm, shell usually longer than wide, endopunctate, anterior commissure rectimarginate, fibrous secondary shell restricted to cardinal process, teeth and tubercles. Ventral valve cemented to substrate by small protegulum. Interarea flat (planodeltidium of Logan and Baker 2013), finely striated with parallel growth lines, hinge teeth prominent, triangular, hemispondylium fused to valve floor, no supporting septum, prongs apically pointed, medially fused, but not usually intact. Dorsal valve smaller than ventral valve, usually elongate; cardinal process bilobate, additional median lobe only weakly developed; dental sockets on either side of cardinal process; calcitic pole attached to bridge and cardinal process, massive with flat sides in adults; median septum variable in width, arched in juveniles, diverging anteriorly, flat or slightly crested posteriorly, changing to concave anteriorly; brachial cavities deep, floored by occasional tubercles, usually found uncovered but sometimes with delicate canopy where preserved, rows of heavy ridges radiating towards the centre or bouffant-like aggregations of shell; peripheral rim with tubercles.	en	Logan, Alan, Bitner, Maria Aleksandra (2013): New records of Recent Brachiopoda from the Red Sea with a description of a new species.

FC5087EAFFA9FFF1FF6437E014667909.taxon	discussion	Remarks. Lüter and Sieben (2005, p. 188) have outlined the history of this species, culminating in the subsequent loss from the National Museum of Natural History in Washington of the sole specimen, the holotype, described by Dall. Fortunately, 12 of the original topotypes collected by Andrews in 1909 are in the Natural History Museum in London and 6 in the Humboldt University Museum in Berlin and in addition there is topotypic material in Berlin collected from Flying Fish Cove by a Western Australian Museum expedition to Christmas Island. One of these is figured here (Fig. 4 F). Details of the characteristic patterns of shell aggregations in the brachial cavities of the dorsal valve are shown in Figs. 4 C, F and I. The Red Sea specimens are smaller than those from Christmas Island and the median lobe of the cardinal process is less well-developed but in other features it corresponds closely to the eastern Indian Ocean species. The species is slightly more common than Minutella minuta in the collections from the Red Sea and has been found at more localities, mostly in the Sudan (Table 1). A single juvenile (Fig. 4 J – L) from Dahab, Gulf of Aqaba, Egypt was collected by Zuschin beneath a colony of the coral Acropora at 10 m depth.

Material. 42 specimens (28 bivalved specimens, 8 ventral valves and 6 dorsal valves), mostly from localities in the Sanganeb reef areas and Suakin Archipelago off the Sudanese coast, and in the Gulf of Aqaba, Egypt (see Table 1).

FC5087EAFFABFFFCFF64367214977A20.taxon	discussion	Remarks. This species is the commonest brachiopod in the Red Sea. It is characterized by its thin shell, small size (length of ventral valve rarely exceeding 2 mm: see also comments on the holotype measurements in Bitner et al. 2008) and numerous, gently rounded ribs. The investigated specimens are consistent with the specimens of this species recorded by Logan et al. (2008) from the Red Sea. The specimens of A. jacksoni described from the Persian Gulf (Bitner et al. 2008) differ slightly from those studied here in having more marked ribs. In outline and ornamentation the specimens from the Red Sea are similar to A. cuneata (Risso) from the Mediterranean Sea, however, they lack a pink-red wash between the costae, characteristic for A. cuneata.

FC5087EAFFABFFFCFF64367214977A20.taxon	discussion	Remarks. The material described here consists of separate valves. By its ornamentation this species is easily distinguishable from other Argyrotheca species of the Red Sea. In ornamentation it resembles A. grandicostata Logan, 1983 from the Canary Islands but it differs in having a much longer hinge line (Logan 1983 b). In their very broad hinge margin the studied specimens are close to A. angulata Zezina, 1987 from the Mozambique Channel but they can be easily distinguished from the latter species by their heavy ribbed ornamentation while A. angulata is sculptured by four feeble ridges (Zezina 1987).	en	Logan, Alan, Bitner, Maria Aleksandra (2013): New records of Recent Brachiopoda from the Red Sea with a description of a new species.
