Key to world species of
Holostaspis
(females)
1. Dorsal shield setae
J5
and
Z5
similar in length; anterolateral angles of anal shield slightly extended, with pointed margins (
Figs 33
,
57
); epistome with well-rounded apex.................................................................. 2
- Dorsal shield setae
J5
shorter than
Z5
(
Z5
= 1.5–
3 x
J5
); anterolateral angles of anal shield normal, with curved margins (
Figs 2
,
44
); epistome with tapered apex........................................................................ 3
2. Podonotal and opisthonotal setae similar in length, vertical setae (
j1
) and setae of dorsal hexagon (
j5
,
z5
,
j6
) similar in length; with two unpaired accessory setae between
J1
and
J3
(
Fig. 33
).....................
Holostaspis isotricha
Kolenati, 1858
- Opisthonotal setae 2–3 times as long as podonotal setae, vertical setae (
j1
) 1.5 times as long as setae of dorsal hexagon (
j5
,
z5
,
j6
); with one unpaired accessory seta between
J3
and
J4
(
Fig. 57
).................
Holostaspis oophila
(
Wasmann, 1897
)
3. Vertical (
j1
) and clunal setae (
Z5
) conspicuous, thicker than other dorsal shield setae:
j1
longer than other anteromedial setae (
j2–j6
),

Holostaspis montana
(Berlese, 1904)
- Vertical (
j1
) and clunal setae (
Z5
) not as conspicuous:
j1
never longer than other anteromedial setae (
j2–j6
), and
Z5
similar in size to
S5
............................................................................................ 4
4. Poststigmatic section of peritrematal shield notably extended beyond coxa IV, almost reaching anterior margin of metapodal platelet; epigynal shield tapered posteriorly, cuneiform; clunal setae (
Z5
) relatively short (
Z5
<
J4
)............................................................................
Holostaspis iranica
(
Babaeian & Nemati, 2014
)
comb. nov.
- Poststigmatic section of peritrematal shield normal, not extending beyond coxa IV; epigynal shield regularly curved posteriorly, rounded; clunal setae (
Z5
) relatively long (
Z5
>
J4
)....................................................... 5
5. Peritremes shorter, with anterior ends reaching middle of coxa II; no unpaired accessory setae between
J1–J5
; metapodal platelets conspicuously elongate and narrow.............................

comb. nov.
[? =
Holostaspis acuminata
(Berlese, 1903)

- Peritremes longer, with anterior ends reaching middle of coxa I; at least one unpaired accessory seta between
J1–J5
; metapodal platelets short and wide, suboval......................................................................... 6
6. Dorsal shield not completely covering dorsal idiosoma, exposing strips of lateral and posterior soft integument (
Fig. 19
); anal shield (
AS
) wider than long, markedly distant from epigynal shield (ES) (
AS
– ES = 1.5–
2 x
AS
length) (
Fig. 21
); two posterolateral setae (
pl1
,
pl2
) on tibia III and genu III–IV, five ventral setae on femur I (
Figs 26–29
).......................................................................................
Holostaspis flexuosa
(
Michael, 1891
)
comb. nov.
- Dorsal shield completely covering dorsal idiosoma; anal shield longer than wide, close to epigynal shield (AS– ES <0.5 x
AS
length); one posterolateral seta (
pl1
) on tibia III and genu III–IV, four ventral setae on femur I........................ 7
7. Dorsal setae shorter:
J5
