Remarks.
Tambila majuscula
was described from a single specimen (referred to in Distant’s description as the ‘unique carded specimen’) with the following data: ‘South
India
; Chikkaballapura (T.V. Campbell)’.
T. gravelyi
was described from an unknown number of specimens (syntypic) with the following data: ‘
Bombay
Pres., Sutara Distr.: Yenna Valley, Medha (F.H. Gravely)’.
T. majuscula
resembles
T. greeni
in male genitalia characters but differs in having a stouter style apophysis and the basal plate like process broadly conically rounded (compared to more angular in
T. greeni
. The apical apophysis of the style is more slender in the specimens from Thekkady compared, for example to the
type
of
T. gravelyi
from Yenna Valley, Satara. Colouration is also variable sometimes with dark brown markings on the head and the pronotum forming well defined patches. The mesonotum may or may not be pale or yellow and in some specimens the mesonotum has the same colour as the rest of the thorax. Some specimens have been collected from Jack fruit tree (
Artocarrpus
heterophyllus
) and sandal tree (
Santalum album
).
