Fig. 1 in Pectinaria nusalautensis (Pectinariidae, Annelida): a new polychaete species from Maluku, Indonesia

Fig. 1. Distributional map of Indonesian pectinariids. Dark grey and white areas indicate Indonesian islands and nearby regions. Pectinaria nusalautensis, new species, and (?)P. brevispinis were collected from the same island. The record of A. capensis is doubtful due to such a long distance between South Africa and Sunda Strait that may restrict the distribution of the species. Pectinaria brevispinis was originally described from the Philippines and was later recorded to occur in Indonesia by Caullery (1944), but this record cannot be verified.

Fig. 1 in Why many Indonesian marine species remain undescribed: a case study using polychaete species discovery

Fig. 1. The cumulative number of Indonesian polychaete species described (the black solid line), projected to the end of the 21st century with a 95% probability. The upper and lower red dashed lines, as well as the red solid line, are the projected species discovery trends assuming great, little, and medium taxonomic efforts, respectively, being made to shift the pre-existing trend.
