Abstract

Integumental pore signatures supplemented by routine morphological characters were studied in the females of five species of Thermocyclops Kiefer, 1927. Both techniques reveal structures with potential significance to taxonomy. Examples of these include a protruding spine of the sixth antennular segment, and a big opening near the genital pore. Bilaterally symmetrical, species-specific pore groups are found on the cephalosome, metasome and urosome, while conserved pores exist on the rostrum, on well-defined zones of the cephalosome, metasome, urosome and on the furcal rami. Exceptionally, asymmetry in these pore patterns may occur.
