Etymology
: The specific epithet (Latin, adjective: small) alludes to the relatively small body size, one of the characters distinguishing this species from the sympatric
S. galiberti
.
Description
: Body length 3.0–
3.8 mm
; length of forebody
1.5–1.7 mm
. External characters (
Fig. 23
) similar to those of
S. marratus
.
♂
: sternite VII without distinct modifications; sternite VIII (
Fig. 24
) weakly oblong, posterior excision moderately large, approximately 0.15 times as deep as length of sternite; aedeagus (
Figs 25–26
) of distinctive morphology,
0.57 mm
long; ventral process slender; internal sac with dark membranous structure, but without pair of sclerotized spines.
Comparative notes
:
Sunius migrus
differs from all other species of the
S. manasluensis
group by the shape of the male sternite VIII and above all by the distinctive morphology of the aedeagus (shapes of ventral process and of internal structures). It is additionally distinguished from the sympatric
S. galiberti
by the smaller and more slender body (
S. galiberti
: length of forebody
1.8–1.9 mm
).
Distribution and natural history
: The
type
locality is situated on Phulchoki, a mountain near Kathmandu in Central
Nepal
. The altitudes range from
2500 to 2600 m
.
