A new scleractinian coral species, Pachyseris inattesa
sp. n., is described from the Red Sea. Despite a superficial resemblance with some species in the agariciid genus Leptoseris with which it has been previously confused, P. inattesa
sp. n. has micro-morphological characters typical of the genus Pachyseris.
This genus, once part of the Agariciidae, is comprised of five extant
species and is widely distributed throughout the tropical Indo-Pacific.
It is currently incertae sedis as a result of recent molecular
analysis and appears to be closely related to the Euphylliidae. A
molecular phylogenetic reconstruction including P. inattesa
sp. n., the genus type species P. rugosa, and P. speciosa,
all present in the Red Sea, was performed using the mitochondrial
intergenic spacer between COI and 16S-rRNA. The results confirm that P. inattesa
sp. n. is a monophyletic lineage closely related to the other Pachyseris species examined.
