Etymology
: The specific epithet (Latin, adjective: black) alludes to the nearly completely black coloration of the whole body.
Description
: Body length 7.0–
8.5 mm
; length of forebody
3.3–3.6 mm
. Coloration: body completely black, except for the reddish to dark-brown tarsi, the reddish apical maxillary palpomere, and sometimes the dark reddish-brown antennomere XI.
Elytra with punctation not subject to sexual dimorphism, dense, but near scutellum not extremely dense (similar to the condition in female
Z. pindarae
). Abdominal segment VII on whole surface with sparse non-setiferous micropunctation. Other external characters (
Figs 260–262
) as in
Z. pindarae
.
♂: shapes and chaetotaxy of tergite and sternite VIII as in
Z. pindarae
; median lobe of aedeagus 0.9–1.0 mm long and shaped as in
Figs 263–264
; paramere (
Fig. 265
)
1.3 mm
long, much longer than median lobe, and with rather long and slender apical lobe.
♀: tergite and sternite VIII as in
Z. pindarae
.
Comparative notes
:
Zyras morulus
is readily distinguished from the highly similar and evidently closely related
Z. pindarae
particularly by black tibiae, different punctation of the male elytra and of the abdominal tergite VII, by a basally much broader ventral process of the aedeagus (ventral view), and (both absolutely and relatively) distinctly longer parameres with a longer and more slender apical lobe of the paramere.
Distribution and natural history
: The
type
specimens were collected in four localities in the
Dhaulagiri
and Annapurna ranges (
Map 4
). The species appears to be confined to high-altitude habitats; the elevations range from approximately 3300 to above
4100 m
. One specimen collected in June is slightly teneral.
