Colouration and structure as in generic description. In some specimens veins marked with brown. Forewing 2.4x as long as wide. Some individuals with hind wings well-developed.
Male genitalia
. Pygofer dorsal margin declivous and concave, posterior margin almost truncate, not bilobed. Subgenital plate held vertically, in lateral view broadened posteriorly with rounded apex and with basal transverse suture. Style with anterior part shorter than posterior part, with apex of apophysis broad. Connective with stem as long as arms and with narrow apex. Aedeagus with well-developed dorsal apodeme, aedeagal shaft dorsally curved near base and then strongly anteriorly recurved with two triangular projections, one on dorsal surface near base and another much larger on ventral surface subapically, gonopore apical, shaft apex widened with lateral angles produced and horn-like, held in tubular anterior projection of segment X. Sternite of segment X produced into short posterior and much longer anterior projections.
Female genitalia
. Sternite VII more narrowly V-shaped compared to other species (
Fig. 4D
). Valvula II as in
D. robustus
(
Fig. 5L
).

Etymology
. The species name refers to the area of distribution of the species as presently known, i.e., South
India
.
Remarks
. This species occurs in two forms, one with hind wings well developed (macropterous) and another with hind wings absent (brachypterous). These forms differ morphologically as indicated in the genus description as far as the structure of the forewings and the thorax are concerned.
D. sudindicus
closely resembles the sympatric
D. robustus
but differs in being more slender and longer in addition to the characters of the male genitalia. This species is unique among the known species of
Daimachus
in having triangular projections on both dorsal and ventral surfaces of the aedeagal shaft.
