(Described as Mesocriconema kirjanovae from Castillo and Vovlas, 1992):
Females in glycerine (n = 15):  Measurements in Table 1.  Body ventally arcuate, tapering toward both extremities, especially posterior end.  Body annules retrorse, posterior edges smooth, sometimes with very fine crenation.  Anastomoses very rare.  Lip region not set off; four small submedian lobes present equally spaced around labial disc.  Oral opening I-shaped.  Second head annule wider than first, 20.6+ 0.26 (20-22), 16.0+ 0.47 (14-18), respectively.  Stylet moderately robust; knobs forwardly directed, 11.5+ 0.50 (11-12) wide.  Excretory pore about 100 form anterior end (Rex = 22 [21-23]); at level of esophagus base or anterior.  Spermatheca broadly oval to almost round, filled with spherical sperms.  Vulva open; anterior lip slightly protruding as small flap, ending with two thorn-like projections.  Vagina slightly curved, VL>VB.  Tail conical, uniformly decreasing to single or bilobed terminus.  Anal opening distinct, pit-like, usually located two, rarely three annules posterior to vulvar opening.
Fourth-stage juvenile female:  Similar to the adult female in all morphological characteristics, the only exception being the posterior edges of  body annules, which are characterized by distinct crenate posterior margins.
Male: not found.
Habitat and locality:  Specimens were collected around roots of Erica sp. at Capileira, Sierra Nevada, Granada, southeastern Spain.
