Aguapanela
Perafán & Cifuentes
gen. nov.
Type
species:
Aguapanela arvi
Perafán, Cifuentes & Estrada
sp. nov.
Etymology.
Aguapanela
is a noun taken in apposition and refers to a non-alcoholic drink, traditionally from the northern Andes of South
America
, mostly popular in
Colombia
.
Aguapanela
literally means "panela water" that refers to a sweet tea-type drink made from evaporated sugarcane pulp.
Diagnosis.
Aguapanela
gen. nov.
differs from other theraphosid genera by the combined presence of plumose stridulatory setae on the coxae, trochanters and femora of legs I and II (
Figs 1–12
), and
types
III and IV urticating setae and also by the reduced number of labial cuspules (
Fig. 15
), the scopula is wide and divided only on tarsal IV, and scopula are absent on metatarsus IV. Males differ from those of other
Theraphosinae
by lacking a tibial apophysis on leg I (
Figs 21–22
) and having a palpal bulb with the subtegulum less extended than usual in
Theraphosinae
, an elongated curved embolus, ventrally concave, with two prolateral keels (PI and PS) very flat and developed on the dorsal edge (
Figs 17–20, 24–25
). PI sub-apically truncated (
Fig. 27
). Females differ from those of other
Theraphosinae
by having spermathecae with two digitiform elongated and granulated seminal receptacles, distally wide and rounded, attached to a semicircular wide membranous base (
Fig. 16
).

Affinities.
(See
Table 1

Pérez-Miles
et al.
(1996)
,
Perafán (2010)
and
Bertani & Guadanucci (2013)
,
types
I and IV urticating setae are synapomorphies for two distinct groups within the subfamily, with some reversions/homoplasies. The presence of
type
IV urticating setae on
Aguapanela
gen. nov.
indicates a relationship with the basal group of
Theraphosinae
(
Pérez-Miles
et al.
1996
;
Perafán 2010
), which is composed by

The male palpal bulb of
Aguapanela
gen. nov.
is similar to that in one of the internal clades of the basal group of
Theraphosinae
proposed by
Perafán (2010)
, including
Bumba
,
Phrixotrichus
and
Euathlus
; untwisted embolus with a curvature forming a ventral concavity and prolateral keels developed on the dorsal edge of the embolus.
Aguapanela
gen. nov.
could be placed within this clade. In contrast, the other internal clade, along with
Agnostopelma
and
Munduruku
, has an embolus straight or with a hard or soft twist on its axis, which generates a dorsal concavity and prolateral keels developed on prolateral side and ventral edge.

Another distinctive character shared with some genera of the basal group of
Theraphosinae
is the reduced number of labial cuspules, present in
Agnostopelma
,
Bumba
,
Magulla
,
Melloleitaoina
,
Phrixotrichus
,
Tmesiphantes
and some
Euathlus
species.
The absence of a male tibial apophysis, underdeveloped prolateral keels and the general morphology of the spermathecae, with two divergent digitiform receptacles, is reminiscent of
Agnostopelma
. However, it differs by the presence of scopula on tarsus IV (absent in
Agnostopelma
), stridulatory setae on legs I and II, the general morphology of the male palpal bulb, female with normal tarsal (very short in
Agnostopelma
), and spermathecae with seminal receptacles attached to a semicircular wide membranous base.
