Head yellow; vertex and frontal tubercles can vary from brown (somewhat
darker than the rest of head) to black. Pronotum, pro- and mesosternum yellow.
Scutellum yellow to black. Metasternum black with yellow posterior and lateral
margins in pale specimens, or black in dark specimens. Abdomen dark brown to
black. The first 3 antennomeres yellow, the rest black. Legs yellow, tarsi and
apical parts of tibiae often infuscate. Elytra metallic dark green or blue.
Labrum transverse, covered by several pale setae, anterior margin sinuate.
Anterior part of head semiopaque, covered by microsculpture and by several long
pale hairs, vertex dull, coarsely and densely punctured. Interantennal space with
small deep groove. Frontal tubercles small, subtriangular, slightly elevated above
vertex, semiopaque, covered by microsculpture. Vertex densely covered with
short pale hairs. Antennae slender, 0.65-0.85 times as long as the body, length
ratio of antennomeres 1 to 11: 13:6:12:16:16:16:17:14:12:11:12.
Pronotum transverse, 1.80-2.00 times as broad as long, widest at the first
third, narrowed anteriad and posteriad, semiopaque, densely covered with coarse
punctures and short pale hairs. Surface with feebly depressed median line, laterally
with 2 large deep depressions. Anterior margin slightly sinuate, lateral
margins rounded, posterior margin almost straight. All margins thinly bordered.
Anterior angles widely rounded, posterior angles obtusely angulate, rounded.
Scutellum small, subtriangular, with rounded apex, covered by small dense
punctures and short pale hairs, semiopaque.
Elytra almost parallel, slightly widened backwards, semiopaque. Humeral
calli well developed. Elytral surface very densely covered with small confused
punctures and short pale hairs. Epipleura distinct, gradually narrowed to apex.
Macropterous.
Ventral surface lustrous, finely punctured and covered by pale hairs.
Basimetatarsomere 1.4 times as long as two following metatarsomeres combined.
Body length 4.10-6.10 mm (holotype 4.30 mm).
The shape of aedeagus as in Fig. 20.
Sexual dimorphism: Male: Antennomeres 1 to 5 with very long pale hairs, last
visible sternite with very large semicircular incision, claws bifid. Female:
Antennomeres 1 to 5 with moderately long pale hairs, last visible sternite complete,
claws appendiculate.
DISTRIBUTION
India and Pakistan.
DIAGNOSIS
A. bertiae n. sp. is variable in colour. Pale specimens (including holotype)
have yellow scutellum and yellow head with brown vertex, dark specimens
(populations from Goa, Bombay and Nagpore) have vertex and scutellum black.
Except the colour difference I am unable to find any other morphological character
(including the structure of aedeagus) to distinguish these two colour forms.
