Longior zayasi Coy, García & Alvarez, 1993 incertae sedis

General.

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.
