Phonorhynchopsis capillaris Diez, Sanjuan, Reygel & Artois View in CoL sp. n.

( Fig. 1 View FIGURE 1 D–F, 2G–H)

Material and distribution in Cuba. Observations on two live specimens, whole mounted afterwards, one of them designated holotype (FMNH http://id.luomus.fi/KV.602), the other one reference material (HU VIII.3.02), from El Masío (type locality) (June 30, 2016), intertidal, in very fine sand, upper 10 cm of the sediment, area with strong wave action, salinity 33 ‰.

Etymology. The epithet capillaris refers to the general morphology of the accessory stylet, which is as thin as a hair (Lat. capillum = hair).

Diagnosis. Species of Phonorhynchopsis with a prostate stylet type IV slightly bent in the middle, 57–60 µm long, 8–10 µm wide proximally and 5 µm subdistally, distal end rounded. Accessory stylet type IV slender, 284– 300 µm long, five times longer than the prostate stylet, proximally 10 µm wide, with the same width in the rest of the length (2 µm). Distally ending in a sharp tip, claw shaped.

Description. Animals 0.9–1.2 mm long measured on the whole mounts. Body translucent; proboscis small, about 10% of the body length; a pair of pigmented eyes behind the proboscis. Pharynx in the middle of the body.

Male copulatory structures organized as in P. haegheni . Prostate stylet type IV ( Fig. 1D View FIGURE 1 , 2H View FIGURE 2 ) slightly curved in the middle, 57–60 µm long, 8–10 µm wide proximally, 5 µm subdistally in both specimens, distally rounded. Accessory stylet type IV ( Fig. 1 View FIGURE 1 E–F, 2G) slender and slightly undulating, 284–300 µm long, 10 µm wide proximally, 2 µm wide in the middle and further distally. Sharp distal tip, claw shaped and preceded by a small dilatation in both specimens ( Fig. 1F View FIGURE 1 ). Accessory gland type IV oval shaped and larger than the prostate gland, proximally connected with small extracapsular glands. Paired testes located behind the pharynx. Bursa bipartite. Paired vitellaria extending from the pharynx to the caudal end of the body.

Discussion. See the Discussion after the description of P. sublinguatus sp. n.
