Diagnosis.
General body color brown to orange brown; posterior margin of pronotum orange; pronotum with small slight pruinose areas posteriorly. Humeral angles spinose. Forewing brownish, with a narrow basal whitish macula starting from humeral angle and ending adjacent to posterior margin of pronotum; centrally with small pruinose areas between cells; at apex another pale yellow macula on central region, with slightly whitish areas surrounding it (
Fig. 19
B). Legs without spines. Male proctiger with a small median elevation. Paramere narrow at base, with rounded apex (
Fig. 20
E).

Discussion.
This species is easily identified for being the only of the genus with spinose humeral angles (
Fig. 20
B). Another
Veliinae
with similar shape is
Stridulivelia alia
(
Drake, 1957
)
, which possesses stridulatory devices on hind femur, absent in
P. spinifera
. The species of the genus
Steinovelia
Polhemus & Polhemus, 1993
generally also bear well-developed humeri, similar to obtuse spines; however they have lateral tubercles on metasternum, absent in
Paravelia
. A wide variation was observed on the degree of development of the humeral spines of
P. spinifera
, with some specimens presenting spines much smaller than those illustrated by
Polhemus & Polhemus (1984a)
.
