Carapace.
Red to dark reddish brown, longer than wide, ovoid with thoracic area broader than the cephalic. Chelicerae yellow with gray tinge,

Abdomen.
Oblongate, black with white median and lateral spots,posterior end with or without a pair of small humps.
Paratype
male has a white cross median band and
paratype
females with a median white longitudinal band aborted before posterior humps and white lateral bands, in cases of lateral bands interrupted, four white spots on each side present. Posterior end of female abdomen blunt and subtruncate in some

females.
Palpal organ with a long, slender and strongly curved tip of median apophysis; paracymbium oblique and rounded at tip; palpal scale indistinct; femur has three (
1-2

patella
with two very long dorsal spines subequal in length.
FEMALE.
Similar to male except for more robust body size and simple spination in tibia I. Posterior end of abdomen usually blunt and subtruncate with humps visible viewed posterolaterally. Eye diameter (mm): PME (

Diagnostic Features
. This new species closely resembles
Hyposinga sanguinea
(C.Koch,
1845
)
but differs from the latter in the following features, namely, (
1
) possessing long and slender median apophysis strongly curved to partly sinuate at tip, (
2
) different markings on the abdomen, (
3
) obliquely rounded tip of paracymbium, (
4
) absence of palpal scales, (
5
) spination and length of spines in tibia I, and (
6
) epigynum with a pair of converging oblongate spermathecae.
