Type
locality.
Barway
(near Chota Nagpur),
India
.
Diagnosis.
Femora brown with apical sixth or seventh dark brown; tibia brown; apical two thirds of Ant 1 black; elytral outer angles slightly dentate; aedeagus with apical lamella short, round at apex (
Fig. 99
).
Description.
Length
9.2–10.5 mm
, width
2.6–3.1 mm
. Black with green luster, mixed with some copper luster, apical third of Ant 1 black, basal two thirds of Ant 1, Ant 2–11 brown; mandibles and palpi brown; tibia and apical sixth or seventh of femora dark brown, basal two-thirds of femora brown. Head with vertex slightly convex, densely punctate; Ant 1/Ant 3

3.54 (3.31–3.69); labrum with medial lobe slightly protruded anteriorly; genae short, distinctly tumid; eyes large, 2.7 times as long as genae. Pronotum densely punctate, PL/PW

1.21 (1.16–1.27), widest slightly before middle; apical angles round; lateral margins slightly widened from apical angles to widest point, strongly narrowed behind, then sinuate to basal angles; basal angles obtuse, pointed laterally; lateral furrow indistinct; basal foveae shallow; middle line fine. Elytra short and wide, EL/EW

1.76 (1.69–1.85), EW/PW

2.35 (2.28–2.50); intervals nearly flat, densely punctate; outer angles slightly dentate. Protarsomere 3 slightly asymmetrical in male; tarsal claws with 5–6 long pectinations, length of individual pectination subequal to width of claw base (
Fig. 61
). Aedeagus with apical lamella thin, very short, apex round (
Figs. 99–100
).
Distribution.
Barway and
Bombay
in
India
.
Etymology.
This species is named for its discovery, which was unexpected.
Remarks.
Members of this species are very similar to those of
D. geniculatus
(Klug)
. In fact, we had not distinguished this species from
D. geniculatus
(Klug)
until the specimens were dissected for genitalia comparison. Males can be distinguished from those of
D. geniculatus
(Klug)
by the short and round lamella of the aedeagus. Moreover, femora of both sexes of this new species are brown with dark brown apex, whereas the femora of most
D. geniculatus
(Klug)
specimens, including those of the
holotype
, are typically yellow with a black apex. Some specimens of
D. geniculatus
(Klug)
do possess brown femora (
e.g.
, from
Vietnam
and Sumatra), but the apex is still black, not dark brown.
