All metasomal segments longer than wide in both sexes. Telson elongate, with aculeus markedly shorter than vesicle. Pectinal teeth number

males. Setation formula of tarsomere II of legs: 6-7/5: 7-8/6: 7-8/6: 8/6.
DESCRIPTION. The adults are 84 (female) and 88–110.7 (male) long. The habitus is shown in
Figs. 1–6
. For position and distribution of trichobothria of pedipalps see

); ventral trichobothria on patella number 14–16. Chelal trichobothrium
Dt
is located on the fixed finger, considerably distal of the fixed finger juncture. Trichobothria
ib–it
are positioned on the distal one-third of the fixed finger. Spacing of chelal trichobothria
V

and
V

is more than three times the distance than that found between
V

and
V

. The mesosoma is matte in the male and glossy in the female; the male has more elongate telson and markedly longer metasomal segments (
Tab. 1
). The fingers of pedipalps are almost straight, without exhibiting any sexual dimorphism (
Figs. 14 and 17
).

Coloration
(
Figs. 1–6
). The base color is uniformly yellow to yellowish brown. The pedipalp fingers and anterior margin of carapace are black. The chelicerae are pale yellow with reddish denticles.
Pedipalps
(
Figs. 13–29
). The elongated pedipalps are sparsely hirsute and finely granulated. The femur bears four granulate carinae; the ventroexternal carina is incomplete. The patella bears five coarsely granular carinae. The chela bears four to six carinae, of which median internal and dorsal carina may be weak and incomplete. The dentate margin of the movable finger is armed with two parallel rows of denticles extending the entire length of the finger, including external and internal granules that appear to indicate six or seven subrows. The dentate margin of the fixed finger is armed with one or two parallel rows of denticles with external and internal granules that appear to indicate five or six subrows.

Metasoma and telson
(
Figs. 1–6
,
30–31
). The metasoma and telson are sparsely hirsute and smooth to very finely granulated. The metasomal segments I–IV bear a total of 7 finely granulate carinae composed of spiniform granules, only a single ventromedian carina is present. The fifth segment bears five carinae, lateral carinae are replaced by an irregular row of minute granules. The telson is strongly elongate, with the aculeus shorter than the vesicle.
Carapace and mesosoma
(
Figs. 7–10
). The carapace longer than wide lacks carinae but has a deep sagittal furrow with a forked, V-shaped furrow on each side in the posterior part. The anteromedial margin of the carapace is strongly concave. Present are a pair of median eyes and three lateral eyes. The carapace and mesosoma are densely covered by different
types
of granules, minute to strong. The sternum is quite elongate, more than 1.5 times longer than wide. The anterior portion of the sternum is as wide or wider than its posterior aspect. Tergites I–II lack carinae, whereas tergites III–VI bear a sagittal carina. Tergite VII bear five incomplete carinae. Sternites III–VI lack carinae and are finely punctate, whereas sternite VII bears two smooth carinae. The pectinal tooth count is
9 in
the female and
13–15 in
the males. The pectinal marginal tips extend the proximal four-fifths of the third sternite in females and one-third the length of the fourth sternite in the male. The pectines have three marginal lamellae and six (female) to ten (male) middle lamellae. The marginal lamellae bear several white (female) or reddish setae (male), the middle lamellae and each fulcrum bear one to three these setae. The genital operculum is oval in male and pentagonal in female.

Chelicerae
(
Figs. 11–12
). The chelicerae dentition is as follows: the movable finger’s dorsal edge has one large subdistal (
sd
) denticle, its ventral edge is smooth lacking ventral accessory (
va
) denticles. The dorsal distal denticle (
dd
) is approximately the same size as its ventral counterpart (
vd
). The fixed finger’s median (
m
) and basal (
b
) denticles form a bicuspid. Ventral accessory (
va
) denticles are lacking on the fixed finger’s ventral surface.

Legs
(
Figs. 32–35
). All legs are finely granulated on dorsal surfaces. The tarsomeres are hirsute with setae and macrosetae including ventral microsetae. All legs are without laterodistal lobes and a prolateral pedal spur is present, the retrolateral spur being absent. Tarsomere I on legs I–III has 5-7/5-7 spiniform setae. Spiniform formula of tarsomere II = 6-7/5: 7-8/6: 7-8/6: 8/6.
