Venter
. Humeral shields in ventrolateral position, bearing setae
c
2, with small spinules, more slender than dorsal body setae, patterns on humeral shields similar to those of dorsal shields. Coxisternal shields completely fused, reticulate, except central region of posterior coxisternal shield. Coxisternal shields bearing three pairs of setae (
1a
,
3a
, and
4a
). Three pairs of setae (
ag
1-3) on aggenital shield. Anogenital covers bearing three pairs of pseudanal setae (
ps
1-3).
Legs
. Leg I 200 (180–210), leg II 175 (170–185), leg III 150 (143–155), leg IV 190 (175–198). Chaetotaxy of leg segments as follows: coxae 2–2–2–2, trochanters 1–1–2–1, femora 6–4–3–2, genua 4(κ)–4(κ)–1–1, tibiae 7(ϕ,ϕρ)–6(ϕρ)–6(ϕρ)–6(ϕρ), tarsi 14(ω)–10(ω)–8(ω)–7. Genua I and II with solenidion κ.
Gnathosoma
.
Chelicera 43 (35–40), palp 85 (80–90). Subcapitulum with two pairs of adoral setae (
ro

m
and
n
) proximally.
Male
and other immature stages.
Unknown.
Etymology.
The specific name
indiscretus
means undivided in Latin, referring to the metapodosomal and opisthosomal shields being incompletely divided.

Remarks.
This new species resembles
Ledermuelleriopsis plumosus
Willmann, 1951
and
L. ayyildizi
Doġan,
2004
in general appearance. It can be easily distinguished from these species by the metapodosomal and opisthosomal shields being incompletely separated. This species is also similar to
L. bisetalis
Doġan,
2004
in that the metapodosomal and opisthosomal shields are incompletely separated, but in the new species the dorsal body setae are homeomorphic whereas they are heteromorphic in
L. bisetalis
and the ventral surfaces in these two species have dissimilar patterns.
In
L. bisetalis
and
L. indiscretus
sp. nov.
, the hysterosomal shield is incompletely divided. We consider them intermediate species between the genera
Ledermuelleriopsis
and
Eustigmaeus
, and currently regard them better placed in
Ledermuelleriopsis
.

Remarks.
This species is known only from
Turkey
and can be easily distinguished from others by having heteromorphic dorsal body setae, the differing dorsal and ventral patterns, and the metapodosomal and opisthosomal shields being incompletely separated. Our specimens identified as
Ledermuelleriopsis bisetalis
exhibit all the characters of the
type
specimens.

Remarks.
This species is known only from

and is similar to

Willmann,
1951
in general appearance, but in this species humeral setae
c

Ledermuelleriopsis ayyildizi
in all respects except the ventral surface is faintly reticulated in some specimens.
