DIAGNOSIS:
Hadruroides leopardus
appears to be most closely related to
H. graceae
and
H. udvardyi
.
Hadruroides leopardus
may be distinguished from
H. graceae
by means of the macrosetal count of metasomal segment V.
Hadruroides leopardus
possesses 12–18 ventral setae and 3–5 lateral setae, whereas
H. graceae
possesses 7–8 ventral setae and 6–8 lateral setae. The hemispermatophore is similar in the two species, but the lamina is less inclined in
H. leopardus
. Both species may be further separated by means of the dimensions of the pedipalp chela: in
H. graceae
, the length:width ratio of the chela is 5.00–5.41 (♂) and 4.46– 5.12 (
♀
), whereas in
H. leopardus
the ratio is 3.93–4.54 (♂) and 4.23–4.64 (
♀
). The ventral surface of metasomal segment IV, which is densely granular in
H. graceae
(
fig. 15C
) and smooth in
H. leopardus
, provides another diagnostic difference between these species. The lateral surface of metasomal segment V is also more granular in
H. graceae
(
figs. 15A
, 16A) than in
H. leopardus
.
Hadruroides leopardus
may be separated from
H. udvardyi
by means of the granulation of the telson and the carination of sternite VII, metasoma, and pedipalps.
Hadruroides udvardyi
is in general more granular than
H. leopardus
.
The VSM carinae comprise small granules on sternite VII and metasomal segment I in
H. udvardyi
, but are obsolete (sternite VII) or absent (segment I) in
H. leopardus
. The DL carinae of segment V are complete and granular in
H. leopardus
, but granular in the anterior half of the segment only in
H. udvardyi
. The vesicle is smooth in both sexes of
H. udvardyi
, but granular in female
H. leopardus
. The pedipalp patella DI carina is smooth or comprises small, scattered granules in
H. leopardus
, but complete and granular in
H. udvardyi
. Additionally, the pigmentation pattern of the carapace, tergites, and metasoma is more pronounced, especially on metasomal segment V and telson, in
H. udvardyi
.
DISTRIBUTION:
Hadruroides leopardus
was described from Puerto Eten in the coastal desert of
Lambayeque
Department, northern
Peru
(fig. 1). We confirm the presence of this species at Eten and additional localities around Chiclayo up to an elevation of
498 m
(fig. 3A). The known locality records of this species occur in the equatorial dry forest ecoregion (
Brack, 1986
), located between the Pacific Ocean and the western slopes of the Andes at elevations below
1300–1500 m
, in southern
Ecuador
and the
Cajamarca
,
Lambayeque
,
Piura
, and
Tumbes
departments of northern
Peru
. Records of
H. leopardus
from
Loja
in
Ecuador
(
Maury, 1975
) are probably referable to
H. udvardyi
(
Lourenço, 1995
)
. Records of
H. leopardus vittatus
from Baños del Inca in Cajamarca (
Pocock, 1900
) are probably the result of mislabelling by P.O. Simons, who also mistakenly labelled ‘‘Baños’’ as a locality for
H. charcasus
, a species that occurs only on the western slopes of the Andes. The specimens of
H. leopardus vittatus
and
H. charcasus
were probably collected along the road from Eten to Baños. Based on data from our fieldwork in Cajamarca,
H. carinatus
is the only
Hadruroides
species
occurring at Baños del Inca.
ECOLOGY: The vegetation in the area inhabited by
H. leopardus
is characterized by shrubs, cacti, and scattered trees, e.g.,
Bursera graveolens
(Kunth) Triana and Planch. (Burseraceae)
,
Capparis
sp. (Brassicaceae)
,
Ceiba insignis
(Kunth) Gibbs and Semir (Malvaceae
)
,
Loxopterigium huasango
Spruce ex Engl. (
Anacardiaceae
),
Prosopis pallida
(Humboldt and Bonpland ex Willdenow) Kunth (Fabaceae)
.
Hadruroides leopardus
is sympatric with
H. charcasus
.
