Diagnosis.
Promere (
Fig. 9
) triangular, with no apical serrated lobe, medial surface of promere coarse. Anterior process of opisthomere (
Fig. 10
) rudimentary, shorter than posterior process, the latter better developed than in the other two subspecies. This peculiar shape of opisthomere visible from every direction (
Figs. 11–13
).
Vulvae similar to, but a bit thinner than those of
M. p. kochi
females (see there).
Remarks.
Due to the small sample size (
5 specimens
altogether, but only
1 male
and
2 females
with body segments) body size parameters can not be suggested. In our case, body length and height seemed to be the smallest among the subspecies: the single male was 23.8 mm long (proposed range for males:
21–28 mm
(Verhoeff 1907))
, 1.7 mm high, with (44+2+T) segments, in the developmental stadium X; females were 29.9–30.1 mm long, 2.5–2.7 mm high, with (44+0+T)–(46+1+T) segments and in the developmental stadium XI. Differences in vulva structure of this subspecies may not be significant; this needs further investigations, involving more female specimens.
