Emended diagnosis:
The following character combination is diagnostic for
H. papalotl
. Male palpal bulb with slender embolus, longer than tegulum,
SA
ends at embolus retrolateral face (
Fig. 21A, C
); VG deep (
Fig. 21D
). The posterior curvature of
SA
occurs at the base of the embolus and forms an angle of 90° (
Fig. 21C
). Embolus strongly curved retrolaterally on distal third (
Fig. 21A, B
). Metatarsus I curved (
Fig. 20I
). Ocular tubercle slightly reduced and PME slightly reduced; periocular pigmentation only strongly marked on anterior eye row (
Figs 20D
,
22A
). Urticating setae arranged in one dorsomedian patch, brown in colour, with anterior and posterior margins notched medially, with rounded edges (butterflyshaped) (
Figs 20C
,
22B
). Spermathecae receptacles are straight or nearly so; receptacles can vary from short and wide to large and thin (
Fig. 21C, D
).
Hemirrhagus papalotl
differs from most
Hemirrhagus
species
by the posterior curvature of
SA
, which forms an angle of 90°. It differs from
H. gertschi
and
H. valdezi
sp. nov.
by the urticating setae being arranged in one dorsomedian, butterfly-shaped patch.

Palp: embolus slender, longer than tegulum.
SA
ends at embolus retrolateral face. The posterior curvature of
SA
occurs at the base of the embolus and forms an angle of 90°. VG deep (
Fig. 21A–D
).
Urticating setae:
type
VI
arranged in one dorsomedian patch, brown in colour, with anterior and posterior margins notched medially, with rounded edges (butterfly-shaped). The margins are clearly defined (
Fig. 20C
).
Colour pattern: in ethanol the colour is brown, with the carapace, legs, and palps darker. In live specimens the general colour is very dark brown, with femora and carapace darker than rest of the body (
Fig. 1G
).
Distribution and natural history:
Known only from Gruta de Aguacachil/Zacatecolotla in
Guerrero
,
México
(
Fig. 48
). The species lives only inside the cave; specimens were collected on walls at a depth of
20 m
from the entrance (
Fig. 1H
). Females laid fixed hammock egg-sacs in the cave wall; these were fixed between two protuberances on the wall (
Fig. 1I
). The females with egg-sacs were found close together, each protecting their egg sac. One of the egg-sacs contained
63 eggs
.
