Head and 1 st pediger segment fused, but the line of fusion can be clearly seen in the stained specimen, 4th and 5th fused. Posterior thoracic margin emarginate in the dorso-lateral region and rounded posteriorly. Anal segment with a tuft of hairs on the ventral aspect. A1 over-reaches the caudal rami by about the last three segments. A1 24-segmented (segments 8-9 fused, 24-25 separate).

In Mxp the proportional lengths of the two basal segments as 46 to 65.; the rounded prominence at the distal end of the 1st basal segment bears very fine spinules, from this lobe arise 3 setae and a forwardly-directed nipple-like prominence, which bears a very small blunt process. P4 bears a row of 13 fine needle-like spines on the 1st basal segment.

 Issued from : J.C. von Vaupel Klein in Crustaceana, Supplt 9, Studies on Copepoda, III, 1984. [p.72, Fig.11, g]. Chirundinella magna. Structure of Mx1, terminal configuration of setae plus the 'blunt tooth (= tubular pore) on the endite of basis (Ba2) (plumosity and/or spinules on setae, as well as hairs on lobe, omitted, right appendage in anterior view). Showing the usual Euchirella complement of, from anterior to posterior: short proximal seta (p), long central seta (c), blunt tooth (dotted outline) and shortest, distal seta (d). Contrary to E. curticauda (see Fig.11, a), a full euchirellinid complement, arranged as in Euchirella but though seta (d) and (4) are smaller sized relative to (p) and (c), the conditions are essentially the same as in Chirundina streetsii (Fig.11 f ) in Chirundinella magna .
