Etymology.
Noun in apposition taken from
type
locality.
Diagnosis.
The male palp of
A. janauari
sp. nov.
is similar to that of
A. bochica
,
A. guatavita
,
A. pae
,
A. quimbaya
,
A. zipa
and
A. bifidus
sp. nov.
, with only two short dPED (no vPED; Fig, 18C). Among these,
A. janauari
sp. nov.
(
Fig. 18
D) seems closer to
A. guatavita
(see
Galvis 2017
: fig. 5C) and
A. bifidus
sp. nov.
(
Fig. 21
D) by having similar RTA and RvTA (see note below). However, the projection on the basal portion of the embolus is absent in
A. janauari
sp. nov.
(
Fig. 18
C), rounded in
A. guatavita
(see
Galvis 2017
: fig. 5A) and bifid in
A. bifidus
sp. nov.
(
Fig. 21
C).
Note.
The structure in
A. janauari
sp. nov.
and
A. bifidus
sp. nov.
named herein as the RTA was referred in
A. guatavita
by
Galvis (2017)
as DTS—dorsal tibial spur. On the other hand, Galvis’s RTA in
A. guatavita
is possibly homologous to the structure referred herein as RvTA. Nonetheless, the homology among these structures is yet to be determined.
