Kaloplocamus acutus Baba, 1955

( Figure 25 A–B )

Material examined. Three specimens. MB28-004683, ZM, 13 Jun. 2013, 8m, 20mm; MB28-0 0 4741, ZA51, 26 Sep. 2013, 10m, 8mm; 1665, NN, 19 Oct. 2016, 12m, 4mm.

Habitats. Subtropical rocky reefs and tropical coral reefs.

Occurrences. Zavora and Nuarro.

Geographic distribution. Western Indian Ocean. Madagascar (Gosliner et al. 2008) and Mozambique.

Remarks. No clear differences can be seen between the specimens from Mozambique and the original description of K. acutus ( Baba 1955) . Nevertheless, the colour varied slightly between specimens. Valdés & Gosliner (2008) reviewed specimens of K. acutus from the Pacific Ocean and in the same year suggested in their field guide that the photographic record of a specimen from Madagascar is likely to represent a different undescribed species (Gosliner et al. 2008). One of the specimens ( Fig. 25B ) found in Mozambique bears the same colour pattern than the specimen from Madagascar and differs from Baba’s description in colouration details. In order to be certain that they are the same species, molecular and anatomical analyses comparing both morphotypes are necessary.
