Dipoena ericae
new species
: (6–8) Male: (6) palp, ventral, (7) body, dorsal, (8) body, lateral. (9) Epigynum: ventral (E, embolus; T, tegulum). Scale bars: 0.25 mm.
Diagnosis.
The male of
Dipoena ericae
new species
resembles that of
D. cordiformis
Keyserling, 1886
(see Levi, 1963: 175, fig. 244) in the embolus filiform (
Fig. 6
) with pointed apex, but differs by the embolus shorter, with a less prominent distal end and in the trajectory of the sperm duct in the tegulum (
Fig. 6
). The female of
Dipoena ericae
is close to
D. cordiformis
(see Levi, 1963: 175, figs. 245-247), but differs from it in the colour pattern and shape of the abdomen and epigynum in ventral view by having an anterior, sclerotized area on the epigynum (
Fig. 9
).
