Pronoides brunneus
Schenkel, 1936
.
Diagnosis.
Pronoides
can be recognized by the following characters: carapace about 1.2 times longer than its width; female, juvenile and adult, abdomen with a pair of obvious anterior humps dorsally (
Figs. 1
,
10
); epigynal plate with a depression on each lateral side (
Figs. 2
,
11
); male femora I with more than six prolateral macrosetae (
Figs. 6
,
16
); palpal embolus strongly curved and L-shaped in prolateral view (
Figs. 9
,
13
).
Pronoides
is similar to
Pronous
Keyserling,
1881
in the arrangement of eyes, but can be distinguished from the latter by the following characters: the PMEs are far from the PLEs, while the PMEs are near to PLEs in
Pronous
(
Schenkel 1936
,
Levi 1995
); the fourth legs are shorter than the first legs, while the fourth legs are longer than the first legs in
Pronous
(
Levi 1995
)
; epigynum with scape, while a scape is absent from the epigynum of
Pronous
(
Levi 1995
)
.
Pronoides
is similar to
Cnodalia
Thorell,
1890
in body shape, but can be distinguished from the latter by the following characters: abdomen longer than wide, while abdomen wider than long in
Cnodalia
; epigynal scape longer than that of
Cnodalia
; male femora I with more than six prolateral macrosetae, while with two or three prolateral macrosetae in
Cnodalia
.
Description.
Carapace yellow brown, pear-shaped, longer than wide. Cephalic region raised. Both eye rows recurved, posterior eye row wider than anterior one. MOA trapezoidal, wider than long, narrower in front than in back; PMEs largest. Clypeal height is larger than AME diameter. Labium wider than long. Sternum shield-shaped, longer than wide. Legs strong, with a few macrosetae. Leg formula: 1243. Abdomen longer than wide, with a pair of anterior humps dorsally in females. Epigynal scape short and ligulate. Spermathecae one pair, large and spherical.
Male smaller, abdominal dorsum lacking a pair of anterior humps. Palpal patella with two long macrosetae; conductor membranous, median apophysis large, with a distal hook.
Composition.
The genus
Pronoides
comprises two species,
P. brunneus
Schenkel, 1936
and
P. sutaiensis
n. sp.
, both distributed in the eastern Palaearctic.
Pronoides ampliabdominis
Song, Zhang & Zhu, 2006
was described based on a single female
holotype
collected from Fanjing Mountains,
Guizhou Province
,
China
. To date, no male has been found. After reexamining the female
holotype
(deposited in MHBU,
Hebei Province
), we found its abdomen wider than long, a short epigynal scape with lateral rim, and in particular, legs I and II with extremely long prolateral tarsal claws. All of these characters conform to the diagnosis of
Cnodalia
, not
Pronoides
. We therefore transfer this species to
Cnodalia
, and form a new combination,
Cnodalia ampliabdominis
(
Song, Zhang & Zhu, 2006
)
new comb.
