Habitus. Probably faded, yellow except a faint brownish ocellar spot and an ochre flagellum. WL 10.3 mm.
Male. Unknown.
Female ( Fig. 305 View FIGURES 305–308 ). As for the complex, a shallow rounded notch in the sclerotised caudal edge of S8.
Egg ( Fig. 306–308 View FIGURES 305–308 ). Elongate oval, on average 357*213µm (n=4),>20 typical specimens without collar and>20 dextrogyrous striae ( Figs. 306–307 View FIGURES 305–308 ). Operculum with a few cells on its small conical top. Egg striae with broad bare costae and narrow sulci which have 1 row of micropunctures along each side. Micropyles are minute holes in the sulci next to which the rows of micropunctures are interrupted.
DNA ( Figs. 491–492 View FIGURE 491 View FIGURE 492 , 496 View FIGURE 496 ). Only the female holotype from Guinea was sequenced with the genome skimming approach, resulting in only 3,102bp of mitochondrial, protein-coding genes. It is poorly supported (43.9/90/0) as sister to N. orthonema n. sp. (see N. orthonema n. sp. above). Together, they are maximally supported (100/100/100) as sister to N. spironema n. sp..
Notes. Several specimens with eggs with a collar ( Fig. 308 View FIGURES 305–308 ) are with doubts assigned to N. filamentosa n. sp.: collar and anchor cavity seem to be variable and we notice no other differences. Striation of eggs differs from N. orthonema n. sp. and N.spironema n. sp. and is the same as in members of the N. excisa and N. sjostedti operational complex.
Etymology. An adjective derived from Latin filamentum, a thread, an allusion to the structure of the anchor, with threads instead of a solid stem.
