Symplegma brakenhielmi: Monniot C. 1983 View in CoL and synonymy; Monniot C. & F. 1997; Monniot F. 2016b; Rocha & Costa 2005. Stations: AM 34; AR 136 (MNHN S1 SYM 92)

The thin encrusting colonies are grey with a transparent tunic. The anatomy is that described by Van Name (1945), Monniot C. (1983), Monniot C. & F. (1997). The branchial structure is characteristic; there are 4 longitudinal vessels on each side but 2 vessels on the left side do not reach the base of the branchial sac but join the dorsal lamina ( Fig. 10A View FIGURE 10 ). There are usually 9–11 rows of stigmata, sometimes 9 as in Fig. 10A View FIGURE 10 . The testis vesicles are lobed and this peculiarity represents the main difference with S. viride View in CoL living the same habitat. The distinction between both species is not clear in the literature. A discussion concerning the Caribbean Symplegma View in CoL species was given by Monniot C. (1983) and also by Monniot C. & F. (1997) with a new record of S. brakenhielmi View in CoL from the Arabian Gulf. The general geographic distribution according to several authors’ citations cannot be ascertained.
