Roewer, 1959: 187
;
type
species:
Evippomma squamulatum
(
Simon, 1898
)
.
Diagnosis
This is the only known genus of
Lycosidae
in which the body (mainly, the cephalothorax) is densely covered in scale-like, leaf-shaped setae (
Figs 1D
,
14B
).
Description
Small- to medium-sized wolf spiders. Tibia I with 4–5 pairs of ventral spines (apart from apical pair). Body covered in scale-like, leaf-shaped setae. These setae are reflective and give live specimens a pearly shine (
Figs 1–2
). Coloration of preserved specimens is brown or yellow. Cephalic region elevated. Ocular area with long macrosetae. Genitalia relatively uniform across genus. Embolus large but not conspicuous. Embolic base in meso-apical position. Tegular apophysis hook-shaped (
Figs 6E
,
7E
,
8E
). Median septum of epigyne widened posteriorly. Atria narrow (
Figs 10E
,
13B
). Spermathecae large and sperm ducts twisted (
Figs 11E
,
13D
). Anterior row of eyes procurved, narrower than PME. ALE smaller than AME.
Natural history
The species inhabit deserts, grasslands and savannas.
Evippomma rechenbergi
is known to construct silk-lined burrows in sand (
Bayer, Foelix & Alderweireldt 2017
), as we recorded for
E. simoni
as well (
Fig. 2D
).
Distribution
Found across Africa, with a new record from
Israel
(but see the section on Composition).
Relationships
Evippomma
is traditionally considered to be related to
Evippa
(Alderweireldt 1992)
. Our molecular phylogeny supports this placement (see Phylogenetic relationships of
Evippinae
based on COI and NADH).
Composition
Seven species are included:
Evippomma albomarginatum
Alderweireldt, 1992
;
E. evippiforme
(
Caporiacco, 1935
)
;
E. evippinum
(
Simon, 1897
)
;
E. plumipes
(Lessert, 1936)
;
E. rechenbergi
Bayer
et al.
, 2017
;
E. simoni
Alderweireldt, 1992
; and
E. squamulatum
(
Simon, 1898
)
. Two representatives of the genus (
E. evippiforme
and
E. evippinum
) that were described from
India
are not considered here as belonging to
Evippomma
, as they have three pairs of ventral spines on tibia I (
Caporiacco 1935
), whereas
Evippomma
is defined as having 4–5 pairs. They might form a separate genus. Moreover,
E. evippiforme
appears to have genitalia uncharacteristic of the other known
Evippomma
species.
