Acumontia echinata Pocock, 1903 

( Figs. 2View FIGURE 2 A –B, 13)

Acumontia rostrata  (part, ♀ only): Pocock 1902: 407, fig. 82 B.

Acumontia echinata Pocock 1903: 441  ; Staręga 1992: 280.

Triacumontia echinata: Roewer 1915: 124  , fig. 33; Roewer 1923: 613; Lawrence 1959: 44.

Type data. 3 holotype, (originally reported as Ƥ syntype of A. rostrata  ), ( BMNH, examined), from MADAGASCAR, [FIANARANTSOA], Ambohimitombo.

Notes. Pocock (1902) firstly mistook this species for females of A. rostrata  and even illustrated one specimen as a female of that species. Later, Pocock (1903) interpreted the “females” as males and females of an undescribed species, which he then described as A. echinata  . Roewer (1915; 1923) simply repeated Pocock’s figures, not having seen any material, and included this species in Triacumontia  .

Diagnosis. Differs from A. pococki  and A. rostrata  by the tubercles of anterior margin of carapace much smaller than cheliceral sockets. Differs from A. hispida  , A. horrida  , A. nigra  , A. roeweri  , A. soerenseni  , A. spinifrons  and A. venator  by having the apophysis of ocularium unbranched. Differs from A. cowani  by the size of spines of areas II –III comparable to the armature of ocularium (and not much smaller). Differs from A. majori  and A. roberti  by spines of areas II –III subequal (from area III not much longer and stouter than of area II), and widely separated at the base. Differs from A. armata  , A. capitata  , A. flavispina  , A. hystrix  , A. majori  , A. remyi  , A. succinea  sp. nov., A. venator  by the presence of two tubercles on dorsum of the trochanter of pedipalps. Differs from A. alluaudi  , A. capitata  , A. cowani  , A. flavispina  , A. hispida  , A. horrida  , A. hystrix  , A. longipes  , A. milloti  , A. remyi  and A. succinea  sp. nov. by the shape of the two ventro-basal apophyses of the femur of pedipalps blunt instead of spiniform. Differs from A. alluaudi  , A. flavispina  , A. hispida  , A. horrida  and A. succinea  sp. nov. by having five tarsomeres in tarsus I of male.
