Logunov, Dmitri V., 2000, A new species of Lyssomanes Hentz, 1845 from Brazil (Araneae: Salticidae), Bull. Br. arachnol. Soc. 11, pp. 343-344 : 8

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.

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.
