Etymology
. The species name is a noun in apposition; a diminutive dedicated to the
type
locality Reserva de la Biosfera “El Cielo”.
Diagnosis.
Live specimens with metallic green luster (
Figs 5–6
).
A. cielito
resembles to
A. faunus
sp. nov.
in the number of lateral abdominal spots, first pair white and second darker (
Figs 6
,
38
), but differs from that species in the male genitalia. The male palp of
A. cielito
is similar to
A. grisae
sp. nov.
and
A. chiapanecus
sp. nov.
, but differs from this species because the embolus in
A. cielito
is less curved than in
A. chiapanecus
and does not have the prolateral keel present in
A. grisae
; the bulb and TL are similar to
A. chiapanecus
, bulb is oval and TL is rectangular without crests (
Figs 62, 63
). Females are recognizable by the epigyne with CD straight (
Fig 8
0–81).

Variation.
Males (n

Natural history.
Specimens were found during the day in a cloud forest, wandering on shrubs and lower leaves of oak trees at
1,065 m
elevation (
Fig. 18
). Mating dance of a male was observed: male stood in front of a female, raised his first pair of legs and moved from side to side, while simultaneously moving the abdomen up and down. Other movements of mating dance of
Anicius
were recorded by
Maddison (1996)
.
Distribution.
Known only from the
type
locality (
Fig. 17
).
