Pratylenchus smoliki Powers, Todd, Harris, Higgins, MacGuidwin, Mullin, Ozbayrak, Powers & Sakai, 2021

Morphology and Anatomy:

Characterized by:

Males relatively abundant; sexually reproducing
Two lip annuli,
Females with a round functional spermatheca and a conoid to subcylindrical tail with a non-crenate, smooth terminus.
En face patterns (per SEM) rectangular to trapezoidal subdorsal and subventral lips adjoining oral disc, but with a clear demarcation between the oral disc and the subdorsal and subventral sectors. The patterns are comparable to those in P. pseudocoffeae, P. scribneri, P. hexincisus, and P. alleni.

Life Cycle:

Assumed to be sexually reproducing based on the presence of males and of sperm in the spermatheca.
