Diagnosis
. Habitus is similar to that of
L. ixobolus
and
L. sericatus
, but females of
L. jalimovi
differ by having a typical heart-shaped epigyne (
Fig. 26
). Unlike
L. ixobolus
and
L. sericatus
, the male palp of
L. jalimovi
has a tapered terminal apophysis and unique small spur on the internal side of the flat shield of embolus and a long process at the base of subterminal apophysis 1 (
Figs 11, 12
). Male palp can also be confused with those of
L. cornutus
and
L. folium
, but it differs by presence of processes at the subterminal apophysis 1.
Description
. Carapace brown with dark pattern. Chelicerae and sternum brown.
Dorsum of abdomen with dark brown
folium
and indistinct white cross (
Figs 1
A, C). Legs yellow, dark annulated with spotted femur.
Male. Total length 6.5–8.5. Carapace 3.2–4.1 long, 2.8–3.8 wide. Length of the first patella + tibia 5.8–7.8. Tibia II not modified, only slightly shorter and thicker than tibia 1 (
Fig. 8
A). Palp as in
Figs 9
A, 10A, 11, 12; bulbus with a long tapered terminal apophysis; subterminal apophysis 1 with a long, lunate process in basal part; subterminal apophysis 2 rounded; embolic tip covered by a flat shield bearing small transparent spur on the internal side; median apophysis with a thinner and longer top part in comparison to shorter, flat and square lower one; conductor trapezoid, as high as wide.
Female. Total length 7.8–11.2. Carapace 3.0–4.6 long, 3.0–3.8 wide. Length of the first patella + tibia 4.7–6.9. Epigyne as in
Fig. 26
; well sclerotised; heart shaped; folded by lateral lamellae; basal lamellae strongly reduced; scapus shortly S-shaped at the base. Copulatory openings near base of scapus, covered by folded margin of lateral lamellae.

Male embolic division of
Larinioides jalimovi
. Letters indicate columns; numbers indicate rows. 11—before maceration; 12—after maceration in NaOH solution; A, B—prolateral view; C, D—retrolateral view. TA = terminal apophysis; STA = subterminal apophysis; EM = embolus.
Distribution
. From the midway along the Amur River to Khabarovsk and south to
South Korea
and possibly to Zhejiang in
China
(
Fig. 33
).
Comments
.
Holotype
female from the Khabarovsk Province, Khabarovsk Pedagogical Institute Biological Station (
June to July 1970
, Yalymova) from Bakhvalov’s private collection seems to be lost.
