Nothocriconemella

Nothocriconemella Ebsary, 1981 (ref. ID; 5958 original paper)

ref. ID; 5958

Diagnosis

Female body 0.27-0.59 mm. Annules 59-134 averaging more than 70, generally retrorse, 4-6 µm thick, smooth. Head annules usually two with the first annule narrower than the second and slightly separated. Head annules may be distinctly narrower than adjacent body annules or of almost equal width. Lip region elevated, round. Pseudolips present. Stylet 50-132 µm, (flexible in species with long stylets). Vulva closed, lips conical. Tail 9-21 annules, conical pointed or conical rounded. VL/VB=1.6(0.9-3). (ref. ID; 5958)
  • Juveniles (male and female fourth stage): Annules with 11-21 rows of generally smooth scales (finely spined in N. orientalis). Stylet present. (ref. ID; 5958)
  • Male: Lateral incisures three or four, bursa small or absent. (ref. ID; 5958)

    Differential diagnosis

    Species of Nothocriconemella n. gen. differ from those of Nothocriconema by having the first head annule narrower and not strongly separated from the second (first head annule wider than second and strongly separated in Nothocriconema), retrorse body annules 4-6 µm thick (rounded annules 8-12 µm thick in Nothocriconema) and by the generally smooth-scaled juveniles (juveniles with obvious spine-tipped scales in Nothocriconema). Nothcriconemella psammophila is apparently a transitional species between Nothocriconema and Nothocriconemella. Characters which point to Nothocriconemella are the 5 µm thick, 85-97 body annules and the smooth juvenile scales. Nothocriconema characters include the first head annule which is wider and moderately separated from the second rounded body annule. However, based on annule number, annule thickness, and juvenile scale characteristics this species is more appropriately placed in Nothocriconemella. (ref. ID; 5958)

    New synonyms

    Nothocriconema arcanum is synonymized with Nothocriconemella pacifica and Nothocriconema mukovum with Nothocriconemella mutabilis. The proposed synonyms cannot be distinguished by annule number, stylet length, excretory pore position, or vulval head and tail features. Their retention as valid species is therefore not justified.
