Material examined. Holotype. MNHN-IK-2000-25, Egypt, Red Sea, 1837, coll. M. Botta.
Description. The holotype is an encrusting colony with a maximin cross-section of 42 x 35 mm ( Fig. 2B View FIGURE 2 ). Its lobes are densely placed, featuring a rounded smooth outline, and occasionally a shallow groove is found on their surface.
The sclerome of the polyps comprises platelets, 0.04–0.07 mm long ( Fig. 5A View FIGURE 5 ). They feature a lateral narrowing, and their surface microstructure has a tuberculate texture in association with a cristate-like one. The sclerites of the surface layer of the lobes are poorly developed dumbbells, 0.06–0.07 mm long, commonly featuring rounded tubercles or some blunt-ended conical ones at both ends ( Fig. 5B View FIGURE 5 ). The interior of the lobes has dumbbells, 0.06– 0.09 mm long, ornamented mainly with a combination of blunt-ended conical and rounded tubercles, and with some pointed conical ones ( Fig. 5C View FIGURE 5 ). Their waist is 0.02–0.03 mm wide and 0.01–0.02 mm long. No sclerites were found on the surface layer of the colony base. The dumbbells from the interior of the base are 0.07–0.10 mm long and are ornamented with pointed conical tubercles and less commonly with blunt-ended conical ones ( Fig. 6 View FIGURE 6 ). The waist of these dumbbells is 0.02–0.04 mm wide and 0.01–0.02 mm long.
Color. The ethanol preserved holotype MNHN-IK-2000-25 is beige-cream.
Remarks. The initial species assignment of L. bottai by Tixier-Durivault (1943a: 439) did not depict the morphological characters of the holotype. Subsequently, a morphological description was presented in the revision of the genus ( Tixier-Durivault 1948: 40-45, Figs. 25–30 View FIGURE 25 View FIGURE 26 View FIGURE 27 View FIGURE 28 View FIGURE 29 View FIGURE 30 ). That description presented one colony ( Fig. 25 View FIGURE 25 ), but the current study found two colonies at the MNHN ( Table 1). The morphological examination of the colony (MNHN- IK-2000-25) and its sclerites corresponded to the amended description, except for a lack of sclerites on the surface layer of the base, noted here but not mentioned by Tixier-Durivault (1948). Such lack of sclerites on the surface layer of the colony base and the morphological features of the polyp sclerites, in particular their composite surface architecture, are considered to be a diagnostic of C. bottai . It should be noted that the current study found such lack of sclerites on the surface layer of the colony base in several other Red Sea Cladiella types ( Table 2). The legend to Fig. 30 View FIGURE 30 in Tixier-Durivault (1948) does not differentiate between the sclerites of the lobe surface and those of the polyps, although both were depicted and the differences between these two sclerite groups are mentioned in the text. A similar error appears in the description of several other species in that revision. The exact location of the type locality in the Red Sea is not indicated.
Alcyonium sphaerophorum var. australiensis Thorpe, 1928 from Western Australia was considered by Tixier-Durivault (1948: 40) to be a synonym of C. bottai . This suggestion requires further examination of the relevant material. Similarly, the record of C. bottai from Taiwan ( Benayahu et al. 2012: 1534) remains to be validated.
