A1 3-segmented and extends to the genital somite, the 1st segment is as long as the next 2 combined.
A2 biramous. Coxa unarmed, basis with 1 inner setae. Endopodite 2-segmented, longer than exopodite; exopodite 8-segmented.
Md biramous, masticatory blade of gnathobase carries 8 teeth, with 1 lateral tooth large and separate from the others. Basis with 3 inner setae. Endopodite 1-segmented, armed with 6 setae; exopodite 4-segmented, with 2, 1, 1, and 2 setae.
