Description:
Body length
3.2-3.8 mm
. Habitus as in
Fig. 101
. External morphology as in
N
..
configens
(
Fig. 102
), distinguished only by the male sexual characters:
: posterior margin of sternite VII very indistinctly concave in the middle, near this concavity with cluster of approximately 20 short modified setae, on either side of this cluster with longer setae directed diagonally medio-caudad (
Fig. 103
); sternite VIII anteriorly with narrow carina posteriorly extending into a long, acute, and apically distinctly bifid process, posterior excision broad and deep, its depth approximately 1/4 the length of sternite (
Figs 104-106
); aedeagus with ventral process of similar morphology as in
N
..
configens
, but more slender apically (
Figs 107-108
).
Etymology:
The species is dedicated to Aleš Smetana, Ottawa, who contributed a considerable proportion of the material treated in the present study and who collected the
type
material of this species.
Figs 101-108:
Neosclerus smetanaismetanai
sp. n.
: habitus (
101
); forebody (
102
); male sternite VII (
103
); male sternite VIII in ventral view (
104
); male sternite VIII in lateral view (
105
); process of male sternite VIII (
106
); aedeagus in lateral view (
107
); apical portion of aedeagus in ventral view (
108
). Scale bars: 101: 1.0 mm; 102: 0.5 mm; 103-108: 0.2 mm.
Comparative notes:
Based on the synapomorphically derived morphology of the male sternites VII-VIII and of the aedeagus, as well as on the similar external morphology, this species is undoubtedly closely allied to
N
..
hlavacihlavaci
and
N
..
configens
, from which it is best distinguished by the deeper posterior excision and the shape of the anterior carina of the male sternite VIII, as well as by the shape of the apex of the ventral process of the aedeagus.
Distribution and bionomics:
The
type locality is situated in
Yilan province
, northeastern
Taiwan
.
The
specimens were sifted from leaf litter and other debris among rhododendron and from moss in a coniferous forest (mainly
Chamaecyparis
)) with the forest floor full of decaying wood covered with lush moss at altitudes of approximately 1900 and
1950 m
in July (SMETANASMETANA pers. comm.)
