Krisna veni
sp. nov.
Figs 97–100
Ochraceous with reddish brown tinge. Eyes chocolate brown.
Male abdominal terga 1–4 and sterna 2 and 3 with well developed apodemes.
Male genitalia
: Pygophore with ventral process arcuate, with elongate oblique furrow in middle section, expansion less prominent dorsal margin with dilation showing a cavity (
Fig. 100
) surface with ridges. Apopysis style of
type
1. Aedeagus with short preatrium, having almost straight ventral margin; aedeagal shaft in lateral aspect with rather straight dorsal margin, distal 0.25 upturned, narrower with transverse rugae, in caudal aspect basal half of shaft broader than apical region with a constriction in middle.
Measurements
: Male
10.5 mm
long,
2.4–2.5 mm
wide across eyes,
2.9–3.2 mm
wide across hind margin of pronotum.

Male
Krisna veni
sp. nov.
97. Aedeagus, lateral view; 98. Same, Caudal view. 99. Ventral pygophore process. 100. Pore on the ventral pygophore process near apex.
Remarks
:
K. veni
can be readily recognized by its dorsal margin of aedeagal shaft being almost straight in basal 0.75; the ventral margin of the preatrium is also straight. The shape of the ventral pygophore process of the
paratype
male is slightly different, being much wider basally and more pointed distally; however, the aedeagus is similar except that the apical 0.25 region is slightly narrower than in the
holotype
.
The species
K. bakeri
,
K. delta
and
K. veni
form a very close-knit group of species of
Krisna
considering the shape of the aedeagus and ventral pygophore process. However, they differ in the detailed structure of the aedeagus.
