Hormonotus modestus
(Duméril, Bibron & Duméril, 1854)
MATERIAL EXAMINED. —
2 specimens
(
ZMB
11241, “
Togo
” without precise locality;
MNHN 2006.2197
,
Sodo Zion
)
.
MORPHOLOGY. — TL
502 mm
and
665 mm
; 15 MSR smooth and oblique, vertebral row enlarged; 228-245 Ven; 86 Sc, paired; anal single; 9 supralabials; 9 infralabials; 1 preocular; 3 postoculars; temporal scale formula 1 + 2.
DISTRIBUTION. — This burrowing species occurs in the forested area of
Togo
. Previously,
Matschie (1893)
,
Sternfeld (1909: 13)
and
Chippaux (2006)
had already recorded its occurrence in the country. Specimens mentioned by
Sternfeld (1908b
,
1909: 13
) were collected at Bismarkburg, now Adele.

MORPHOLOGY. — TL from
310 to 935 mm
; 28-31 MSR, smooth; 202-248 Ven, smooth; 44-68 Sc; anal single; 8-9 supralabials; 8-10 infralabials; 1 preocular; 2 postoculars; temporal scale formula 1 + 2 + 3.
DISTRIBUTION. — This species is very common and present in all ecological regions of the country. It occurs in all ecosystems: savannahs, forest, in urbanized areas, and so on. Additional specimens were collected in Aledjo, Fazao and Huilehui. The species had been recorded from
Togo
by
Matschie (1893)
,
Sternfeld (1908b
,
1909: 11
), from Missahohe, Kete (Kete-Kratchi currently in
Ghana
),
Hulselmans & Verheyen (1970)
, Hulselmans
et al.
(1970), and
Roman (1984)
. Publications of
Trape & Mané (2004
,
2006b
) and
Chippaux (2006)
mentioned the presence of this species throughout Western and Central Africa. However,
Chirio & Ineich (2006)
stated that this nominal taxon is a complex of two species which is in need of a taxonomical revision.
CONSERVATION STATUS. — According to reports of the CITES Division of the DFC
Togo
,
30 specimens
were exported from
Togo
in 2005.
REMARKS
The genus is currently under revision by the senior author of this paper; the results will be presented elsewhere. Nevertheless, in
Togo
and West Africa, the characters of both
Lamprophis fuliginosus
and
Lamprophis lineatus
are quite constant. Both species can be easily separated by the condition of the contact between the upper part of the preocular and the frontal. In all (57) examined specimens of
L. fuliginosus
from throughout West Africa, the preocular is in broad contact with the frontal, whereas these scales are separated in all (12) examined specimens of
L. lineatus
. On the basis of new characters, it appears that there are more than one species under the name
L. lineatus
, especially in Central Africa.
