Notes.
Pocock (1902)
mentioned the
type
series of this (sub)species as consisting in “an adult and two subadult females”. Later,
Pocock (1903: 441)
stated that “the specimens described as
A. rostrata
subsp.
Cowani
[sic.] are males and females of a form which must be regarded as a valid species.”
Roewer (1915
;
1923
) limited himself to repeat this information without seeing the
types
. He also included it in the newly created genus
Triacumontia
, later sunken by
Staręga (1992)
into
Acumontia
.
Lawrence (1959)
reported additional material from Toamasina. This species has never been illustrated.

A. hispida
,
A. horrida

A. longipes
,
A. milloti
,
A. nigra

A. armata
,
A. capitata
,
A. flavispina
,
A. hystrix
,
A. majori
,
A. remyi

A. armata
,
A. echinata
,
A. majori
,
A. nigra
,
A. roberti
,
A. roeweri
,
A. rostrata
,
A. soerenseni
,
A. spinifrons
and
A. venator
by the two ventro-basal apophyses of femur of pedipalps spiniform, not blunt. Differs from
A. alluaudi
,
A. flavispina
,
A. hispida
,
