Lyssomanes romani

sp. n.

Lyssomanes romani  sp. n. ( Figs. 1–4)

Type: Holotype ♂ ( SMNH), Brazil: Amazonas, Rio Negro, Umarituba, 26 April 1924, A. Roman  .

Etymology: This species is named in honour of the famous Swedish collector and explorer of South America, Mr Abraham Roman, who collected the holotype.

Diagnosis: The new species is fairly close to Lyssomanes antillanus Peckham, Peckham & Wheeler, 1889  , L. portoricensis Petrunkevitch, 1933  , L. unicolor (Taczanowski, 1872)  and L. michae Brignoli, 1984  (see Galiano, 1962: pl. III, figs. 8–9 and pl. VI, figs. 1–3; Galiano, 1980: pl. III, figs. 23–24; Brignoli, 1984: figs. 4, 7), but can be easily distinguished from them by the elongated and almost touching embolus and median apophysis (clearly separated in the above species), as well as by the ribbon-shaped conductor (fan-shaped in the above species) (see Figs. 1–4).

Distribution: The type locality only.

Description: Male (holotype): Carapace 2.88 long, 1.98 wide, 1.18 high at PLE. Ocular area 1.35 long. Eye interdistances: AME-AME 1.28, ALE-ALE 1.21, PME-PME 0.83, PLE-PLE 1.90. Diameter of AME 0.63. Abdomen 4.25 long, 1.10 wide. Cheliceral length 1.10. Clypeal height 0.18. Length of leg segments: I 4.00+1.08+4.25+4.68+0.88; II 4.05+1.00+3.98 +4.40+ 0.83; III 4.33+0.98+4.18+5.18+0.85; IV 4.60 +0.85+ 4.25+6.03+1.03. Leg spination: I: Fm d 1-0-1-1, pr and rt 0-1-1; Pt d 1ap; Tb d 1-0-0-1, rt 0-0-1, v 2-2 -2-2; Mt pr and rt 1-0-0, v 2-2 -2ap. II: Fm d 0-1-1-1, pr and rt 0-0-1-1; Pt d 1ap; Tb d 1-0-0-1, pr and rt 1-1, v 2 -0-2-2; Mt pr and rt 1-0-0, v 2-2 - 2. III: Fm d 0-1-1-1, pr and rt 0-0-1-1; Pt d 1ap: Tb d 1-0-0-1, pr 1-1-1, rt 1-0-1; Mt d 2-0-0, v 2-2 -0. IV: Fm d 0-1-1-2, pr 0-1-0; Pt 1ap; Tb d 1-0-0-1, pr 1-1-1, rt 0-1-1; Mt d 2-0, pr and rt 1-1. Coloration (the specimen is rather faded): Carapace yellow, with black around eyes of second, third and fourth rows. Eye field lighter (bright yellow). Sternum yellowish. Maxillae, labium and chelicerae brownish yellow. Abdomen yellow-brown, each side with a wide longitudinal yellow band. Book-lung covers and spinnerets yellow, tinged with brown. All legs and palpi yellow, but femora I and II ventrally with wide longitudinal brown stripes; tibia I also slightly brownish in middle part of segment. Palpal structure as in Figs. 1–4.
