Morphological characterization of Hemicycliophora typica and H. labiata from Venezuela

Abstract

A population of Hemicycliophora typica and one of H. labiata were detected in soil samples collected from the rhizosphere of Bermudagrass (Cynodon sp.) of a golf course in Caracas, Miranda State, and in the rhizosphere of Pythecolobium sp. in Humocaro, Lara State, respectively, Venezuela. Descriptions, measurements and micro-photographs are given of females and fourth stage juveniles of H. typica and also drawings and photographs of females, males and juveniles of H. labiata. The morphometrics of the Venezuelan population of H. labiata are similar to those reported from different places of South Africa, Australia and Sri Lanka. The morphometrics of the Venezuelan population of H. typica are similar to those reported from South Africa, but the stylet is shorter than that of populations from The Netherlands, Poland and Uganda.
