Abstract

Franco-Navarro, F. and I. Cid del Prado-Vera. 2006. Characterization of a Mexican population of Hoplotylus feminas'Jacob, 1960 associated with Quercus crassipes Humb. & Bonpl. Nematropica 36:173-180. A population of Hoplotylus from Mexico State, Mexico, was identified as Hoplotylus feminas'Jacob, 1960 based on similarities in morphological characters with those of this species, including: the female head pattern, the consistent lack of a functional spermatheca, the areolated lateral field with four incisures, the undifferentiated postvulval uterine branch, and the size and shape of the female and male tails. The female head pattern of this Mexican population showed fused submedian lip sectors lacking the pronounced notch on their outer margins unlike those reported for this genus, which have a deep distinct notch. Although most of the females had empty spermathecae, like those of other H. femina populations, a specimen with a full spermatheca was observed. This is the first report of a species of Hoplotylus from Mexico.
