Etymology.
The new species is named after the chocolate ‘Mon Cheri’. Used as a noun in apposition.
Diagnosis.
Mallinella moncheri
sp. nov.
s
hare features such as triangular lateral border of the epigyne, V-shaped epigynal plate with the members of the annulipes-group. Within the annulipes-group, males of
M. moncheri
sp. nov.
are most similar to the males of
M. dhanahami
sp. nov.
as both share digitiform RTA, and black colour bands on either side of the carapace of both male and female but can be separated from it by slender, unbranched embolus (bifurcated embolus in
M. dhanahami
sp. nov.
) and diagonally aligned emobolic base (aligned longitudinally in
M. dhanahami
sp. nov.
) (
Figs 1G
,
8A
;
3G
,
8C
). Females are also most similar to the females of
M. dhanahami
sp. nov.
as both share V-shaped epigynal plate but can be separated from it by deeper anterior depression of the epigyne and triangular lateral borders of the epigyne (digitiform lateral borders in
M. dhanahami
sp. nov.
). (
