COMMENTS. This species was based on a specimen for which Simon did not determine the sex. I have not been able to examine the
type
; however, I have studied a male from the Hamburg museum (
Figs. 1–2
).
Alloscorpiops lindstroemii
(
Thorell, 1889
)
is based on one specimen collected by Leonardo Fea in
Myanmar
(Plapoo, Mt. Mooleyit). Its total length is
68 mm
(
Thorell, 1889: 578
). The position and distribution of trichobothria on the chela and patella of pedipalps have not been published. Ventral trichobothria on the patella number 15 (
Pocock, 1900: 66
), and pectinal teeth number 8 (
Thorell, 1889: 578
).
Scorpiops lugubris
, based on a
24 mm
long juvenile from the same locality (
Thorell, 1889: 583
), was regarded by
Pocock (1900: 74)
as a junior synonym of
A. lindstroemii
.
Kraepelin (1913: 161–162)
doubted the validity of
A. lindstroemii
and thought that it could be a synonym of
A. anthracinus
. He believed the
type
of
A. lindstroemii
to be a female of
A. anthracinus
and their different numbers of pectinal teeth to be only due to sexual dimorphism. I agree with this opinion.

ETYMOLOGY. Named after a book,
Citadelle
, by Antoine de Saint-Exupéry (1948).
DIAGNOSIS. Total length
37–54 mm
. Base color uniformly greenish black to black, legs can be pigmented and telson is yellow with a reddish sting. Pectinal teeth number
10–11 in
males and
8–9 in
females. Patella of pedipalp with 29–34 external (5
eb
, 2–3
esb
, 3
em
, 12– 17
est
, 5–6
et
) and 19–21 ventral trichobothria. Chela of pedipalp bears 11–13 ventral trichobothria. Sexual dimorphism minor, adult males have relatively larger pectines (
Figs. 16 and 17
); there is no difference in length and width of metasomal (
Figs. 18 and 19
) and pedipalp segments, and fingers of pedipalps are almost stright in both sexes (
Figs. 5 and 8
).
DESCRIPTION: Total length
37–54 mm
. The base color is uniformly greenish black to black, legs can be pigmented, sternites are lighter, and the telson is yellow with a reddish sting. Chelicerae are reddish brown and reticulate. For habitus see
Figs. 3–4 and 6–7
. Sexual dimorphism minor.
MESOSOMA AND CARAPACE: The mesosoma is granulated, with one median carina, and the seventh sternite bears four carinae. The entire carapace is granulated, without carinae. The anterior margin of the carapace is markedly depressed in the middle. The carapace bears three lateral eyes of which two are normal and one is reduced. Pectinal teeth number
10–11 in
males and
8–9 in
females.
METASOMA AND TELSON (
Figs. 18 and 19
): The metasoma is finely granulated, with sparse, relatively large granules. The first segment bears 10 carinae, the second to fourth segments bear eight carinae, and the fifth segment bears seven carinae. The dorsolateral carinae of the third and fourth segments posteriorly terminate in a pronounced tooth. The telson is elongate, without granules.

PEDIPALPS: For position and distribution of trichobothria on the patella of pedipalps see
Figs. 9–15
. External trichobothria on the patella number 29–34 (5
eb
, 2–3
esb
, 3
em
, 12–17
est
, 5–6
et
) (
Fig. 13
), and ventral trichobothria on the patella number 19–21 (
Fig. 14
). The chela bears11–13 ventral trichobothria (
Figs. 11
and
15
). The femur and patella are granulated. The femur has five granulose carinae, and the patella has five carinae with pronounced internal twin tubercles. The manus dorsally bears fine rounded granules, which in the central part form a longitudinal carina. The external surface of the chela is densely covered by minute granules. The movable fingers bear straight double rows of granules. The pedipalp fingers are almost straight in both sexes.

AFFINITIES: The described features distinguish
Alloscorpiops citadelle
sp. n.
from
A. anthracinus
. The main difference is in the trichobothrial pattern. Higher number and different positions have also ventral trichobothria on the chela (
Fig. 11
) and patella (
Fig. 14
), but most important is the number of external trichobothria on the patella (
Fig. 13
) of which
A. citadelle
sp. n.
has 29–34 (5
eb
, 2– 3
esb
, 3

, 12–17

, 5–6
et
), whereas
A. anthracinus
has only 23–24 (5
