Mazarredia (Rosacris) fuscipes ( Stål, 1877) comb. nov.

Tettix fuscipes: Stål 1877 ; Mazarredia fuscipes: Hancock 1907 ; Kirby 1910; Bruner 1915; Metamazarredia fuscipes: Günther 1939 ; Blackith 1992; Skejo 2016.

Type material: female holotype deposited in the Naturhistoriska Riksmuseet ( NHRS), Stockholm, Sweden

Type locality: Philippines

Justification of synonymy. The holotype and both recorded specimens of Rosacris antennata syn. nov. are nymphs ( Skejo 2016). All available specimens exhibit typical nymphal morphology, i.e. they lack antegenicular teeth, their pronota are short with compresso-elevated median carinae, and they are wingless ( Skejo et al. 2018). This excludes some important diagnostic characters, but there is still enough evidence to suggest that those individuals represent nymphs of M. (R.) fuscipes comb. nov.

The general colouration of the legs, the position of the bifurcation of the frontal costa, deep fossulae, and the width of the vertex undoubtedly place the nymphs in the subgenus Rosacris stat. nov.. The shape of the vertex in dorsal view (strongly triangular) and the shape of the anterior margin of the vertex (slightly narrowed anteriorly, blunt), along with the shape of the eyes (distinctly narrowed in the dorsal part in frontal view) and the prozonal carinae of the pronotum distinctly curving inwards dorsally fit exactly with M. (R.) fuscipes comb. nov. Additionally, a specimen of M. (R.) fuscipes comb. nov. is known from Mount Isarog, the type locality of R. antennata syn. nov. ( Skejo 2016; Cigliano et al. 2022).

A summary of this species’ nomenclature and photographs of the nymph hitherto assigned to R. antennata syn. nov. can be seen in Fig. 1 .
