Hirstionyssus (H.) keenani Strandtmann and Yunker, 1966. Fig. 6-13. A detailed description of the female will not be given here because the original description by. Strandtmann and Yunker (1966) is adequate. However, a representative specimen from the Venezuela collection has been illustrated. Strandtmann and Yunker (1966) found no males in the Panama material and, although they illus- trated parts of a deutonymph, no description was given. Thus, descriptions and illustrations of the male and the deutonymph are given below. No significant differences were noted between the Venezuela specimens and paratypes from Pana- ma. Measurements of a female H. keenani from Venezuela are given for comparison with other closely related species described Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Brigham Young University.
