The setae on the holoventral shield are shorter than the setae on the ventral and the lateral membranes. The metapodal shields are almost circular. The peritreme reaches to the middle of coxa II. A small peritrematal shield is present, it is rather distant from the parapodal shield which is much smaller than in the female. The legs are rather short, coxa III bears a blunt spur, coxae I and II bear sharp spines, coxa IV has a small seta. Tarsus IV (96 [i long, excluding pulvillus) bears 2 blunt short spurs distally and a similar spur on the row preceding Figs. 68-69. Laelaps pachypus C. L. Koch, female. Fig. 68, dorsum.

It has been found, however, that the female of L. jettmari differs in the following points from L. ekstremi: (a) Setae ri are posterior to setae ii ; (6) the sternal shield is much longer, it is 160 /t long ; (c) the first sternal setae are short and do not reach the hind margin of the sternal shield ; (d) the genito-ventral shield is broad and has no narrow neck. I consider therefore that the validity of Laelaps ekstremi Zachvatkin, 1948, should be 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 British Museum (Natural History).
