Acumontia roberti Pocock, 1903 

( Figs. 4View FIGURE 4 A –B, 13, 14)

Acumontia majori Pocock 1902 a: 407  , figs. 83 A –A 2 (part, ♀ only).

Acumontia Roberti  [sic.]: Pocock 1903: 443.

Acumontia roberti: Roewer 1915 b: 121  ; Roewer 1923: 612; Lawrence 1959: 61; Staręga 1992: 281.

Type data. Ƥ holotype (originally a syntype of A. majori  ), BMNH, from MADAGASCAR, [FIANARANTSOA], Ambohimitombo.

Records. MADAGASCAR, [ANTANANARIVO], Mt Ankaratra, Manjakatompo forest, 2000 m; [FIANARANTSOA], Ambohimitombo; Nosiarivo; Farafangana, Karianga ( Lawrence 1959).

Notes. Pocock (1902) initially mistook a female of this species by a male and included it as a syntype of A. majori  . Later, Pocock (1903) realized it was a female of an yet undescribed species, calling it A. roberti  . Roewer only cited the species without seeing any material of it. Lawrence cited both males and females, but limited himself to note variation on tarsal count of females and did not comment about males. This species has never been illustrated before.

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. armata  , A. echinata  and A. pococki  by the spines of area III contiguous at base. 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. Very similar to A. majori  , differing by having the trochanter of pedipalp dorsally armed with two spines, and by the tubercles on each corner of the anterior margin of carapace.
