Characterization of<i>Nothacrobeles lanceolatus</i>Abolafia &amp; Peña-Santiago, 2003 (Rhabditida, Cephalobidae), a typical species of coastal dunes from Spain

Abstract The nematode Nothacrobeles lanceolatus was described in arid soils from Cabo de Gata-Níjar Natural Park, province of Almería (Spain). Since then this species has not been found again. In study, new data on the distribution and morphological, morphometrical molecular characteristics (based 18S 28S ribosomal DNA) N . is provided. This characterized by having a tessellated cuticle, with its inner layer bearing two rows cuticular punctations per annulus, lips quadrangular eight pinnae, labial probolae bifurcate divergent prongs surrounded pharynx corpus 2.5–4.0 times isthmus length, post-vulval uterine sac 1.4–2.2 corresponding body diameter, female male tails conical, conical mucro acute terminus. phylogenetic position related genus discussed. Additionally, bacteria ( Pasteuria ) fungi Catenaria , Nematocida feeding are showed including light microscopy scanning electron illustrations.
