Abstract
Three new species of Normanellidae are described from the Texas coast, Gulf of Mexico. Normanella texana sp. nov. has limited areolated patterns on the cephalothorax, short P5 exopod and endopod, short caudal ramus and short caudal seta VI-V. Normanella brevispina sp. nov. is characterized by its relatively long caudal rami, and areolated rostrum. Normanella chanhoi sp. nov. has well-developed areolated patterns on the cephalothorax, six-segmented antennule and a smooth apical margin of the rostrum. N. texana belongs to the bolini -lineage, and N. brevispina to the minuta -lineage. Normanella chanhoi establishes a new lineage of its own.
