Abstract

Ogma panamensis n. sp. is reported as a new species.  This species is characterized by submedian lobes and two annuli at the lip region. The first lip annulus is smooth and distinctly wider than the second annulus, which has a fringe of short scales. Body annuli bear a continuous fringe of long and digitate scales with smooth ends. The tail is elongated sharply conoid with a pointed terminus and two to four digitate scales in last slender and longer annuli. Known species of Criconematidae identified in this study were: Ogma fimbriatum, O. hungaricum, O. serratum, Hemicycliophora californica, H. micoletzkyi, H. nucleata, H. sheri, Hemicriconemoides californianus, Gracilacus acicula, and Paratylenchus vandenbrandei. These species were identified from the permanent nematode slide collection of R. T. Robbins and were submitted to the USDA Nematode Collection in Beltsville, Maryland, USA and other institutions, as taxonomic references.
