Scale bars = 0.050 mm except for A (0.100 mm) and F (0.025 mm).
Nota: Prosome 5-segmented; no carapace-like extension present on maxilliped-bearing somite so 1st pedigerous somite completely exposed. Nauplus eye absent. Rostrum small posteroventrally directed, not fused to labrum. Urosome 5-segmented; 1st somite bearing P5, 2nd with paired genital openings either side of ventral midline; 3rd fused to 2nd but line of fusion marked by a complete suture. caudal rami about twice as long as wide, armed with a long inner seta on distal margin, 1 short distal seta, 1 lateral seta and 1 dorsal seta. A1 27-segmented. P5 comprising a large basal segment armed with an outer distal seta, and on oval terminal segment bearing an apical seta.

Rem.:

anchialine cave.Speleophria (Boxshall & Iliffe, 1986). In the latter case the genital openings are usually situated near the middle of the genital complex,n as their original position is at the posterior margin of the genital somite. The position of the genital openings of cavernicola, at the posterior margin of the 2nd urosome somite, suggests that it is a copepodid V stage. In this case the telson (last division of the urosome) will prpbably subdivide at the final moult to give 6-segmented urosome in the adult female. However, the ovary and a single oviduct visible on the right side of the body, the well-developed state of the female reproduvctive system suggest that the specimen should be regarded as a mature adult.
