Diagnosis.
This species is similar to
L. subdianicus
sp. nov.
(
Figs 17 a–d
) in general appearance and the genital organs: but differs in: the embolus being longer; the RTA short stick-shaped versus long spatulate in
L. subdianicus
; cymbium with modification absent in
L. subdianicus
; atrium almost as long as wide versus much wider than long in
L. subdianicus
; the copulatory ducts with fold absent in
L. subdianicus
. This species is also similar to
L. silvanus
Ono, 1980
and
L. coronatus
(Grube, 1861)
in slender embolus, but can be separated from those species by: the RTA digitform (spatulate in
L. silvanus
), the copulatory ducts twist in 1 circle (about 2–3 circles in
L. silvanus
); the cymbium wider than in
L. coronatus
, VTA apically curved prolaterally (curved retrolaterally in
L. coronatus
).
Description. Male

Dorsal shield of prosoma yellow, with sparse long setae, and with a pair of brown bilateral markings. Eye sizes and interdistances: AME 0.13, ALE 0.20, PME 0.06, PLE 0.15, AME

Legs I, II brown; III, IV yellow. Leg measurements: I: 7.60 (2.00, 3.00, 1.60, 1.00); II: 7.90 (2.20, 3.00, 1.60, 1.10); III: 4.60 (1.50, 1.60, 0.90, 0.60); IV: 5.10 (1.60, 1.80, 1.00, 0.70), formula: 2, 1, 4, 3.

-
shaped light black mark posteriorly.
Palp
(

,
i
). VTA strongly sclerotized, apically curved, RTA with a basal projection, distal parts of RTA stick

shaped. The embolus slender and curved anticlockwise, large helix
