Ctenus
spec.
, male from Mt Victoria, Myanmar, palp (44 prolateral; 45 ventral; 46 retrolateral; 47 embolus tip, ventral).
FIGURES 48–50
Ctenus
spec.
, female from Mt Victoria, Myanmar, copulatory organ (48 epigyne, ventral; 49 epigyne, posterior; 50 vulva, dorsal). I + II—two chambers of spermathecae, chamber II functionally between chamber I and fertilisation duct.
Note.
This male exhibited a different distal tip of RTA than the typical
C. natmataung
spec. nov.
(
Figs 45–46
). A malformation seems to be unlikely since both palps show the same shape of the RTA tip. Other palpal structures (
Figs 44–47
) or copulatory organs of the female (
Figs 48–50
) collected with the male as well as colouration of both sexes (
Figs 22–25
) are absolutely congruent with those character states in
C. natmataung
spec. nov.
So far, it cannot be decided whether these specimens (especially the male) are conspecific with
C. natmataung
spec. nov.
and the RTA tip represents a strong intraspecific variation or whether it belongs to a different species. Body length: male 9.9, female 15.3.
