Description:
Body length 3.0-
3.6 mm
. Habitus as in
Fig. 80
. Coloration: head and abdomen blackish; pronotum and elytra dark-brown to blackish-brown, usually at least slightly paler than head and abdomen; anterior margin of elytra and scutellum reddish; posterior elytral margin and pronotal margins usually narrowly reddish-brown; legs and antennae yellowish to reddish-yellow.
Head across eyes 1.20-1.25 times as wide as long; postocular region moderately short, approximately as long as width of antennomere I (
Fig. 81
); punctation coarse and dense, sparser in posterior median area; interstices with very shallow to pronounced microsculpture (always clearly visible in posterior dorsal portion of head); antenna 1.0-
1.1 mm
long. Mouthparts as in
Figs 82-84
.
Pronotum approximately as wide as long and 0.80-0.85 times as wide as head (
Fig. 81
); punctation coarse and dense; midline impunctate; interstices without microsculpture and glossy.
Figs 80-91:
Neosclerus hlavacihlavaci
sp. n.
: habitus (
80
); forebody (
81
); mandible (
82
); labrum (
83
); maxilla (
84
); male sternite VII (
85
); male sternite VIII in ventral view (
86
); male sternite VIII in lateral view (
87
); process of male sternite VIII (
88
); aedeagus in lateral and in ventral view (
89-90
); female tergite VIII (
91
). Scale bars: 80: 1.0 mm; 81: 0.5 mm; 85-87, 89-91: 0.2 mm; 82-84, 88: 0.1 mm.
Elytra short, approximately 0.7 times as long and approximately as wide as pronotum; humeral angles weakly pronounced (
Fig. 81
); punctation dense and rather fine, surface only with subdued shine. Hind wings reduced.
Abdomen 1.05-1.15 times as wide as elytra; punctation fine and dense; interstices with very shallow microsculpture; posterior margin of tergite VII without palisade fringe.
: posterior margin of sternite VII weakly concave in the middle, near this concavity with cluster of approximately 15 short modified setae, on either side of this cluster with longer setae directed diagonally medio-caudad (
Fig. 85
); sternite VIII with almost V-shaped posterior excision, its depth approximately 1/5 the length of sternite, in anterior half with median carina, this carina extended into spinose process posteriorly (
Figs 86-87
), apex of spinose process with few setae (
Fig. 88
); aedeagus of distinctive morphology, ventral process subapically with pronounced tooth in lateral view (
Figs 89-90
).
: sternite VIII posteriorly obtusely angled in the middle (
Fig. 91
).
Etymology:
The species is dedicated to my friend and colleague Peter Hlaváč, Košice, who collected the
type
series, also in gratitude for the generous gift of the
NeoclerusNeoclerus
material he collected in
China
.
Comparative notes:
This species is best distinguished from other micropterous congeners by the morphology of the aedeagus. It is readily separated from the sympatric and syntopic
N
..
glaberglaber
additionally by the presence of microsculpture on the head, the less coarse and dense punctation of the head, the distinctly shorter and anteriorly more distinctly reddish elytra, the absence of a palisade fringe at the posterior margin of the abdominal tergite VII, as well as by the shape and chaetotaxy of the male sternites VII and VIII.
Distribution and bionomics:
The known distribution is confined to three localities in
Fujian province
, southeastern
China
, where the
type
specimens were collected at altitudes of
900-1300 m
. In two localities,
N
..
hlavaci
was collected together with
N
..
glaber
.
