Diagnosis "Carapace elongate-oblong in lateral outline; dorsal margin broadly and smoothly arched, with obscurely indicated posterodorsal angle; greatest height located at midlength; anterior margin narrowly and evenly rounded; ventral indentation deep and somewhat angulate; pos teroventral margin not upswung posteriorly; posterior margin broadly and obliquely rounded, forming some what truncate angle of about 72°; zone of concrescence fairly wide; patch pattern consisting of three variable spots. Male fifth limbs very asymmetrical, with tiny pegs and long dorsal seta; distal hook robust and recurved at 66° in right limb, reduced almost to nothing and curved at 151° in left limb. Female fifth limb slender with fairly long claws. Dorsodistal claw of sixth limb about two-thirds as long as mediodistal claw. Recurved seta of seventh limb rather short, reaching only to middle of podomere II, lined with very fine hairs decreasing in size distally. Furcae rather short, straight, rapidly tapering, with small proxi mal setae. Hemipenis oblong with rounded outlines, with short lobate anterodorsal lamellar flap; copulatory rod fairly short, irregularly bent. Zenker's organ with very small terminal bulb; vas deferens arranged in three loose loops, almost as long as Zenker's organ. (Maddocks, 1990: 112, 113)

Etymology "For the island of Bermuda." (Maddocks, 1990: 112) [details]

Remark Mn. bermudae is much smaller and more elongate than most other species. It is somewhat similar in shape to Mn. horiuli, which also occurs in Bermuda, but is smaller and more elongate, with a more angulate, truncate posterior and dorsal outline and deeper ventral indentation; it also has less tapering male fifth limbs and a slightly less elongate hcmipenis with a lobate rather than triangular anterodorsal lamellar flap. sp. 44, and Mn. succinea are proportionally higher and less equilateral, with more highly arched dorsal margins and more tapering posterior angles. Mn. succinea also has more sinuate, more tapering male fifth limbs. Mn. vargata is similar in size and in its angulate anterior and posterior outlines but is more highly arched dorsally, with a more or less distinct dorsal angle but no posterodorsal angle.
