“…Within the P. ( Pterygodermatites ) subgenus, males present three characters that are useful to discriminate between species: the number of cuticular projection pairs (combs and spines), the number of midventral fans, and the size of spicules [ 13 , 19 , 32 ]. Considering the species of the subgenus P. ( Pterygodermatites ) for which information on males is available, there are differences in the male of P. ( P. ) plagiostoma in the characters spicules size, number of fans, and number of cuticular projection pairs (see Table 1 ).…”

“…Concerning females, the most discriminant characters between species are the prevulvar and total number of cuticular projection pairs, the body level where the transition from combs to spines occurs, and the position of the vulva in relation to the esophagus–intestine junction [ 13 , 19 , 32 ]. In fact, the differentiation of cuticular projections (from combs to spines) occurs at the level of the vulva in P. ( P. ) plagiostoma whereas it occurs at a posterior level in P. ( P. ) aethechini [ 17 ].…”

A redescription of the rictulariid nematode Pterygodermatites (Pterygodermatites) plagiostoma Wedl, 1861, is made by means of light and scanning electron microscopy, including the first data on male specimens. The morphologic study was based on specimens recovered from two Algerian hedgehogs (Atelerix algirus) from Tenerife and Gran Canaria islands (Canary Archipelago, Spain). The main characteristics of P. (P.) plagiostoma males are the presence of 49–53 pairs of cuticular projections, the presence of one or two midventral precloacal fans (generally one), and the size of two unequal spicules, measuring 98–123 µm (right spicule) and 185–236 µm (left spicule). The cloacal papillae are arranged according to the Ascaridida type. They include two precloacal pairs, an unpaired precloacal papilla, one pair lateral to the cloaca, six postcloacal pairs, and a pair of phasmids near the tail tip. Females are mainly characterized by the presence of 71–77 pairs of cuticular projections, with 43–46 pairs of prevulvar combs, by the differentiation from combs to spines at the level of or slightly posterior to the vulva and by the position of the vulva, located posteriorly to the esophagus–intestine junction. Clear differences were found between P. (P.) plagiostoma and related species of the subgenus P. (Pterygodermatites).

“…In some species, infective larvae do not arrest their development in the intermediate host but continue growing and reach an advanced state of sexual development. Pseudorictularia was created to accommodate the species initially described as Rictularia disparilis Irwin- Smith, 1922 and placed into the Physalopterinae (Dollfus & Desportes 1944). However, specific hosts are often needed for the maturation of worms (cf.…”
