Diagnosis.
Very similar to
M. japonica
sp. nov.
, but differing from it as follows: antenna with first flagellomere rather long, approximately 4.5 times as long as pedicel; gena approximately 0.2 of eye height; fore tibia with 2 posterior setae; male abdominal sternite 5 elongated, rectangular, distinctly longer than wide; male cercus slightly slenderer than that of
M
.
japonica
in lateral view.
Distribution.
Indonesia
(
Sumatra
),
Malaysia
(Borneo).
Host(s).
Unknown.
Remarks.
Tachi & Shima (2010)
included this species, as “
Medinodexia
sp.”, in their molecular phylogeny, and it was classified in
Blondeliini
. It is very similar to
M
.
japonica
sp. nov.
in the male and female postabdominal characters, but the male sternite 5 differs distinctly from that of
M
.
japonica
in the long anterior part. This is the first record of this species from Borneo,
Malaysia
. No hosts have so far been recorded for this species. A detailed description was given by
Shima (1997)
.
