Duplominona veracruzensis Curini-Galletti n. sp.

( Fig. 7 View FIGURE 7 )

Holotype. Gulf of Panama, Playa Venado (Veracruz, Panama)(Lat. 8°53’27.07”N; Lon. 79°35’44.16”W), intertidal in silty coarse sand, December 2011: whole mount USNM 1622598 View Materials ) GoogleMaps

Etymology. The specific epithet is coined on the locality of finding.

Description. A minute Duplominona species, about 1.5 mm long. With dot-like rhabdoids, more evident cephalically; clusters of long rhabdoids are present caudally. Caudal tip simple, pointed. Pharynx about midbody ( Fig 1 A View FIGURE 1 ).

Male genital system. With 6 testes in one row. With an ovoid copulatory organ, 50 μm long. Spiny cirrus 35 μm long, provided with about 25 rows of spines. Proximal spines crowded, densely packed, very small, 1.5–2 μm long. Halfway the length of the cirrus, spines change their morphology, and become larger and slenderer, up to 6–7 μm long, less densely packed, and bluntly triangular in shape ( Fig 7 View FIGURE 7 C–F).

Accessory organ 45 μm across, provided with a stylet 13 μm long. It opens to the outside with its own pore, very close to the female pore.

Female genital system. Ovaria and vitellaria as in previous species. With a large pre-penial bursa, with a long vaginal duct, in front of the copulatory organ ( Fig 7 B View FIGURE 7 ). The female duct continues posteriorly to the bursa and opens just behind the prostatoid organ pore through the female pore.

Diagnosis. Species of Duplominona with about 25 rows of triangular spines, 1.5–7 μm long, increasing in size distally. Distal spines bluntly triangular.
