Remarks. Holmberg (1876) proposed Lycosa (Tarantula) maesta for the first time based only on the 16 mm total length of the specimen he examined. Though superficial, this species description was sufficient to make the species description a valid nomenclatural act (see ICZN 1999: art. 6). Holmberg (1881) transfers this species to Tarentula and redescribed it based on a set of approximately 200 specimens collected by Lynch Arribálzaga at the surroundings of Buenos Aires, Argentina. He also clarified (in Holmberg, 1881) that the specimen used to propose Lycosa moesta was pinned, although no type was assigned. This is corroborated by the statement made by Levi (1964): “…Holmberg’s species, mostly from the Buenos Aires vicinity, there exist no types ”. Simon (1885) placed Lycosa moesta within an arbitrary Alopecosa group, which was posteriorly transferred to the genus Alopecosa by Petrunkevitch (1911). After examining Argentinian, Peruvian, Brazilian, and Uruguayan specimens we concluded that are conspecific with the specimens described by Holmberg (1881) but does not fit the Alopecosa diagnosis (see Lugetti & Tongiorgi 1969; Dondale & Redner 1979).

Diagnosis: Males of Tropicosa moesta can be recognized by the short terminal apophysis, which is curved at the base and tapered at the tip ( Figs 18b , 19e ), not abruptly tapered as in Tropicosa thorelli nor straight as in T. baguala . Females of T. moesta can be differentiated by the length of the transverse septum almost equal to the width of the widest part of the median septum ( Figs 16a, d ).

Description. Male (MCTP 35786). Color in ethanol ( Fig. 20a‒f ): carapace brown, covered by short white bristles; narrow uniform longitudinal median yellow band same color as the submarginal bands ( Fig. 20a ). Chelicerae brown, as the carapace. Opisthosoma dark olive with a cardiac mark inside a broad yellow band ( Fig. 20a ). Venter yellow with a black, uniform, spotted band ( Fig. 20e ). Femora I−II brown with ventral and lateral iridescence; femora III−IV paler, with annulations. Ventral scopulae on tarsi legs I−II, thinner than in tarsi legs III−IV.

Palp tibiae cylindrical, slightly wider apically. Cymbium piriform. Distal file on tibia facing a scrapper on the proximal part of the cymbium ( Fig. 19i ). Cymbium with a bunch of apical macrosetae ( Fig. 19b ). Tegulum striated, with a curved sperm duct ( Figs 19e, 19g ). Median apophysis laminar and curved ( Figs 18d , 19e ), triangular, transversal, with ventral process triangular and pointed ( Figs 18b, g , 19h ); terminal apophysis laminar, hyaline, curved and parallel to subterminal apophysis, which is membranous ( Fig. 18b ). Palea rounded partially sclerotized ( Fig. 19f ). Embolus arising from the retrolateral margin of palea, with conspicuous pars pendula ( Fig. 19b ).
