Abstract
The study of material collected during routine monitoring surveys dealing with oil
extraction and aquaculture in waters off Myanmar (North Andaman Sea) and in the
Gulf of Thailand, respectively, allowed us to analyse the taxonomy and diversity of the
polychaete genus Terebellides (Annelida). Three species were found, namely Terebellides
cf. woolawa, Terebellides hutchingsae spec. nov. (a new species fully described and
illustrated), and Terebellides sp. (likely a new species, but with only one available
specimen). The new species is characterised by the combination of some branchial
(number, fusion and relative length of lobes and papillation of lamellae), and thoracic
(lateral lobes and relative length of notopodia) characters and is compared with all
species described or reported in the SW Indo-Pacific area, as well as with those sharing
similar morphological characteristics all around the world. The taxonomic relevance
of the relative length of branchial lobes and different types of ciliature in branchial
lamellae for species discrimination in the genus is discussed. A key to all Terebellides
species described in SE Indo-Pacific waters is presented.
