Description:
Small species,
2.6-3.2 mm
(abdomen extended). Habitus as in
Fig. 38
. In external morphology highly similar to
S. fortespinosus
, but distinguished as follows:
Coloration on average paler: forebody yellowish, elytra of same colour as head and pronotum; paratergites and apex of abdomen reddish to reddish brown. Puncturation of head on average slightly sparser, especially in median dorsal area. Elytra on average slightly shorter and more slender, approximately 0.70 times as long as pronotum (
Fig. 39
).
: sternite VII not distinctly modified (
Fig. 40
); sternite VIII unmodified, except for posterior incision (
Fig. 41
); aedeagus shaped as in
Figs 42-47
, internal sac with series of six stout, long, and distinctly sclerotised spines (
Fig. 47
).
Etymology:
The name (Lat., adj.) refers to the presence of six stout spines in the internal sac of the aedeagus.
Comparative notes:
Based on the male sexual characters, especially the morphology of the aedeagus (shape of apex of ventral process, shape of spines in internal sac),
S. sexspinosus
is the adelphotaxon of
S.
fortespinosus
. Both species are reliably distinguished only by the male primary sexual characters, particularly the shape of the apex of the ventral process (see
Figs 30- 34
,
42-45
), as well as the number and colour of the spines in the internal sac (darker in
S. fortespinosus
than in
S. sexspinosus
).
Figs 38-47:
Sunius sexspinosus
sp. n.
: habitus (
38
); forebody (
39
); sternite VII (
40
); sternite VIII (
41
); aedeagus in lateral and in ventral view (
42-44
); ventral process of aedeagus in ventral view (
45
); apical internal structure of aedeagus in ventral view (
46
); spines in internal sac of aedeagus in lateral view (
47
). Scale bars: 38: 1.0 mm; 39: 0.5 mm; 40-41: 0.2 mm; 42-47: 0.1 mm.
Distribution and bionomics:
The
type locality is situated some
15 km
to the northeast of
Muğla
(
Map 1
).
The
type
specimens were found under stones and sifted from grass roots between limestone gravel on a pasture with shrubs, very close to a field, at an altitude of about
1200 m
(
Fig. 48
)
