Remarks

• Systematics: Slide-mounted adult female with: enlarged setae curved, conical, sides slightly concave, apices slightly rounded, marginal setae slightly larger than other setae on dorsum, particularly on abdomen, abundant over surface; claw digitals expanded; microtubular ducts elongate, with 1 sclerotized area (Miller & González, 1975). The adult females of M. navarinoensis are very similar to those of M. chilensis and M. rhadinothrix. Miller and González (1975) separate the adult females of M. navarinoensis from those of M. rhadinothrix by 1, 19-31 dorsal setae on abdominal segment V on M. navarinoensis (9-14 on M. rhadinothrix); 2, setae on dorsomedial areas of head and thorax noticeably smaller than those on abdominal margin on M. navarinoensis (setae on dorsomedial areas of head and thorax c. same size as those along abdominal margin on M. rhadinothrix); 3, 7-segmented antennae on M. navarinoensis (6-segmented in M. rhadinothrix); 4, tibia:tarsus ratio 0.9-1.1 for M. navarinoensis (0.7-0.8 for M. rhadinothrix), and 5, anal lobes smaller, broader and less protuberant on M. navarinoensis than on M. rhadinothrix. The presence of translucent pores on the hind tibiae of M. navarinoensis can be used to distinguish the adult females from those of M. rhadinothrix where they are absent. (Hardy, et al., 2008)
• Structure: Sac of female is tawny and felted. Adult female is oval (Hoy, 1962a).
• General Remarks: Detailed descriptions and illustrations by Hoy (1962a) and Miller & González (1975).
