It’s a great day for all the wrasse fans out there, as yet another beautiful species of Pseudojuloides has been made known to science. This diverse group now numbers thirteen species in total and has been growing by leaps and bounds in the past few years with the description of P. edwardi in [...]
The cerasinus Group This group exemplifies the difficulties inherent to delimiting “species” of reef fishes. Currently, five are officially recognized, with several more distinctive populations in need of further study. There is very little overlap in their respective biogeographic [...]
The mesostigma Group: Black-spot (mesostigma) & Lightning Pencil Wrasses (P. zeus) Two poorly studied and seldom encountered species are known in this group, both of which make rare appearances in the aquarium trade. P. mesostigma is the more well known of the two, with [...]
The severnsi Group: Royal (severnsi), African (edwardi), & Mauritian (erythrops) Pencil Wrasses The three described species in this group share a number of easily observable characters: 1) A black “hood” covering the anterodorsal portions of the body. 2) A pair of [...]
The elongatus Group: African (argyreogaster), Japanese (cf elongatus), Western (cf elongatus) & Eastern Australian (elongatus) Seaweed Wrasses The four known variants in this group occupy widely separated parts of the globe and are unique amongst Pseudojuloides for preferring [...]
