. Colour: dorsal and
ventral surface black, lustrous; head, antennae, anterior margin of
pronotum and forelegs with metallic, coppery reflections. Each
elytron with a single large yellow spot or subfascia located approxi-
mately 2/3 distad from base, each subfascia extending from lateral
margins to approximately interval 3. Shape and sculpture: head
slightly impressed between eyes and antennal insertions; with
slightly impunctate area between eyes; anterior clypeal margin con-

notum widest at posterior angles, posterior angles acute; with broad medial depression extending from proximity of scutellum nearly to anterior margin; with 4 large shallow lateral impressions, 2 either side of disc; lateral margins setose, setae silver, adpressed; deeply and coarsely punctate; width of punctures greater than that of intervening spaces; intervening spaces slightly granulose - lustrous. Scutellum deeply impressed, granulose. Scutellum deeply impressed, granulose. Elytra coarsely and deeply punctate-rugose; intervening spaces granulose; basal margin rugulose; interval 3 subcostate to approximately 2/ 3 distad, remainder carinate to apex; smooth, slightly punctate in basal 1/2; interval 5 slightly raised – subcostate in basal 1/3; often coarsely punctaterugose; lateral margins serrate in apical 1/2; apices with a small but distinct lateral spine. Ventral surface, including legs, densely setose, prosternum, mesosternum, metasternum, and pronotal hypomeron more so; last abdominal segment rounded apically.

. Size: 9.5 – 13.2
x
3
– 4.1 mm. Large females generally lack metallic reflections, and possess a small, impunctate, area or keel situated between the eyes. A single small female in the
paratype
series possesses metallic coloration similar to the
holotype
and lacks the frontal keel or impunctate area. Last abdominal segment in females as in
holotype
male.

Etymology
. The specific epithet is chosen to reflect the perceived ‘nearness’ to
N. costatus
(Carter, 1912)
.

.
Nascioides subcostatus
differs from all other known Australian species by its distinct black body coloration and single yellow subfascia on each elytron.
