Huffmanela mexicana Moravec et Fajer-Avila, 2000

(Fig. 6)

Material examined. Syntypes, eggs from a fragment of swimbladder of Sphoeroides annulatus Jenyns (Tetraodontidae) . Original registration number in Helminthological Collection of the Institute of Parasitology, Ceské Budéjovice: N-759; material deposited in the collection of MNHN, registration number JNA40.

Because the published measurements of H. mexicana eggs (Moravec & Fajer-Avila, 2000) were close to that of H. balista, the original material was requested for comparative observation. Eggs, measured with the same microscope and methods as for other species mentioned here, were 57.3 ± 2.7 (48–63) × 29.7 ± 2.2 (27– 37) (n = 83). These measurements were different from that of the original description (63–69 × 30–33 including plugs). In addition, it was observed that a few thin filaments were present on the surface of most eggs (Figure 6A); this was not reported in the original description but perhaps can be attributed to the use of differential interference microscopy in the present study.
