Coy et al. (1993) described Longior zayasi, from El Salón, Sierra del Rosario, eastern Pinar del Río Province, Cuba. Althought the females morphology is consistent with the generic definition, examination of the male specimens showed features that disagree with the diagnosis of the male of Longior longicollis, the type species of the genus. These features are:

First cephalic annule notably long, surpassing the stoma length, inflated, forming a truncated cone-like structure. According with Travassos and Kloss (1958), Longior longicollis has a cephalic dilatation hardly conspicuous.

Posterior end finished in a sharply pointed tail, instead of the ventral expansion of the tail cuticle in Longior longicollis that forms a bursa-like structure, referred by the authors as a “ventral valve”.

These discrepancies support the possibility that the males attributed to Longior zayasi are misplaced in this genus. So far, we can not assign these males to a genus, although is possible that they belong to some species of Artigasia Christie, 1934 or Hystrignathus Leidy, 1850 where the females show a long and dilated first cephalic annule. New collections from the locality are needed to clarify the status of Longior zayasi by comparing males with the females in the same host. Meanwhile we consider this species as an incertae sedis.

Coy et al. (1993) established a male specimen as holotype of Longior zayasi. According to the Article 73.1 of the International Code of Zoological Nomenclature “A holotype is the single specimen upon which a new nominal species-group taxon is based in the original publication…”. As a new name becomes necessary for the females described as conspecific with Longior zayasi, below we re-describe and rename such females, including the description of sympatric males that present the diagnostic features of Longior and we consider as conspecific with those females.

Female. Body long and relatively slender. Cervical cuticle without spines. Subcuticular longitudinal striae present. Lateral alae well developed, arising from about two body widths posterior to the basal bulb up to the level of the anus. Head rounded, set-off from body by a single, deep groove, bearing eight prominent, paired papillae. First cephalic annule slightly inflated, about 2 to 2.5 head-lengths long. Stoma long, slender, about 3.5 first cephalic annule lengths long, surrounded by an esophageal collar. Oesophagus consisting of a very elongated, subcylindrical, muscular procorpus less set-off from the isthmus. Basal bulb sub-spherical, valve plate well developed. Intestine simple, sub-rectilinear, its fore region slightly inflated. Rectum short, anus not prominent. Nerve ring encircling procorpus at about 20% of its length. Excretory pore located at about a body width posterior to basal bulb. Vulva a median transverse slit, near midbody, lips not prominent. Vagina muscular, strongly developed, forwardly directed. Genital tract monodelphic-prodelphic. Ovary reflected at about two body widths posterior to bulb, distal flexure about two body widths long. Eggs ovoid, with eight, rough, very prominent, longitudinal ridges not reaching the poles. Oocytes in a single row. Tail conical, subulate, ending in a fine tip.

Male. Body comparatively stout, shorter than female. Posterior region of body ventrally curved. Cervical cuticle unarmed, visibly annulated up to a little distance before the nerve ring. Sub-cuticular longitudinal striae present. Head set off from body by a single groove and bearing eight small, paired papillae. First cephalic annule not conspicuous. Stoma long, surrounded by an esophageal collar. Oesophagus slightly sub-fusiform, diminishing its diameter toward its second half until equaling the diameter of the isthmus. Basal bulb rounded, valve plate developed. Nerve ring encircling procorpus at about 35% of its length. Excretory pore situated at little more than a body-width posterior to basal bulb. Testis single, full of spermatids, commencing at about 1.5 body-widths posterior to bulb. Spicule absent. A large, median, mammiform precloacal papillae situated at a little less than a body width before the posterior end. A pair of dorso-lateral precloacal papillae located at about 0.5 body-widths before the tail tip. Dorsal cuticle of posterior end thickened from level of the latter pair of papillae to the tail tip. There is a cuticular bursa-like structure in the tail end, almost reaching the level of the tail tip.

Longior longior sp. n. differs from Longior longicollis, from Brazil, by having females with the body larger (3.500–4.525 vs. 2.98–3.64) and the tail comparatively longer (c = 6.72–8.54 vs. 9.03–9.33). The vulva is slightly displaced forward in the present species (V% = 50.00–58.01 vs. 57.72–61.81). The tail of the male of Longior longior sp. n. is comparatively shorter (c = 43.33–51.27: 30.66–32.83), and has the tip unreflexed. In Longior longior the nerve ring is displaced to the first half of the procorpus in both sexes, instead of Longior longicollis sp. n. where this structure is situated in the midpoint of the procorpus.

Longior longior sp. n. differs from Longior similis by lacking wide and marked annule in the cervical cuticle of females. Its body is longer (total length = 3.500–4.525 vs. 2.675–3.075) and the first cephalic annule is more inflated. The ovary is reflexed at about two body widths beyond the excretory pore, more posterior than Longior similis where it is reflexed at little less than a body width beyond the excretory pore. Males of the new species differ from Longior similis by having the cervical cuticle markedly annulated instead of Longior similis that presents the cervical cuticle smooth.

Longior longior sp. n. is distinguished from Longior alius García & Coy, 1994 (from Cuba) by having the isthmus shorter and not bent, instead of the isthmus very long and bent of the latter species. From Longior semialata Hunt, 1981, from Saint Lucia, West Indies, differs by the lateral alae that commence before the level of the vulva, the body longer (total length = 3.500–4.525 vs. 2.26–2.63) and the oesophagus comparatively shorter (b = 4.49–5.45 vs. 3.30–3.70). The lateral alae of Longior semialata start at about the middle of the distance between the vulva and the anus.

Longior longior sp. n. can be differentiated from Longior elieri García, Ventosa & Morffe, 2009 (from Cuba) by having an inflated first cephalic annule and by lacking of wide annule in the cervical region. Longior elieri has a not inflated first cephalic annule and the first third of the cervical cuticle widely annulated.

Named after the Latin longior: the largest, being this species the largest in the genus.

All the records of females of Longior longior sp. n. were formerly referred as Longior zayasi and measures of most of them have been published. In order to compare the meristic features between localities a chart with such variables is offered (Table 1).

♂ voucher; Cuba, La Habana Province, Jaruco, Escaleras de Jaruco; in Passalus interstitialis; 16.III.2008; E. Fonseca, J. Morffe, F. Alvarez coll.; CZACC 11.4630.

Male (n = 1) a = 15.66, b = 4.15, c = 54.80, total length = 1.370, maximum body width = 0.088, stoma length = 0.045, procorpus length = 0.260, isthmus length = 0.028, diameter of basal bulb = 0.040, total length of oesophagus = 0.330, nerve ring to anterior end = 0.145, excretory pore to anterior end = 0.500, cloaca to posterior end = 0.025, distance from the mammiform papillae to the posterior end = 0.153, distance from the dorso-lateral papillae to the posterior end = 0.068.

Male body comparatively slender, shorter than female. Cuticle thin, finely annulated. Sub-cuticular longitudinal striae present. Head short, rounded, set-off from body by a single groove, papillae not observed. First cephalic annule not differentiated. Stoma as in the female. Oesophagus with its second half slender than first, hardly set-off from the isthmus. Basal bulb rounded, valve plate developed. Intestine simple, slender, its fore region dilated. Anus inconspicuous. Nerve ring encircling procorpus at about 40% of its length. Excretory pore located at about 1.5 body widths posterior to basal bulb. Testis single, full of spermatids, commencing just behind excretory pore, its second third slightly inflated. Spicule absent. A large, mid-ventral, precloacal, mammiform papilla situated at about 1.5 body widths before the tail tip. A pair of dorso-lateral, precloacal papillae at little less than a body width before the tail tip. Dorsal cuticle of the posterior end thickened from the level of the pair of papillae to almost the tail tip. Ventral cuticle expanded, forming a bursa-like structure with the distal end terminating before the tail tip. Tail short, conical, ending in a rounded tip. Posterior end slightly reflexed toward dorsal region.

The male of Longior similis resembles Longior longicollis mainly by the form of the tail endbut differs by having the nerve ring displaced to the first half of the procorpus, at about the 40% of its length (in Longior longicollis the nerve ring is at the middle of procorpus). The procorpus of Longior longicollis is cylindrical in all its extension, while in Longior similis it is slightly wider in its first half. The tail is also comparatively shorter in the Cuban species (c = 54.8: 30.66–32.83).

From Longior longior sp. n., the other species where the male is known differs by having the cervical cuticle without visible annule and the tail tip reflexed toward the back. Longior longior sp. n. has the cervical cuticle annulated up to about the first third of the procorpus and the tail tip unreflexed. Also, Longior similis has a comparatively shorter oesophagus (b =4.15 vs. 3.13–3.63).
