Two new Metacephalus DeLong & Martinson, 1973 species (Hemiptera: Cicadellidae: Portanini) from Brazil and proposed synonymy with Paraportanus Carvalho & Cavichioli, 2009 Author Souza, Stephanie Pereira De Author Takiya, Daniela Maeda Author Felix, Márcio text Zootaxa 2017 4281 1 176 185 journal article 28749 10.11646/zootaxa.4281.1.16 feabbf19-bfad-4221-926e-bff60860abb6 1175-5326 816047 A4810522-0262-495F-921F-9616AFFB9D77 Metacephalus albocrux ( Figure 1 ) Metacephalus albocrux DeLong & Martinson, 1973 : 225 , Figs. 1 –6 ( sp. nov. ). Diagnosis . Crown ( Fig. 1 ) with distinct white cross-shaped marking on black background on anterior half. Pronotum ( Fig. 1 ) with distinct paired subparallel longitudinal orange stripes. Pygofer lobes (Fig. 5) with apical processes with acute ventral point. Aedeagus (Figs. 9, 10) with shaft with broad preapical dorsal process and pair of elongate apical processes directed ventrally. Measurements (mm) . Males: body length, 5.3–5.5; crown length, 0.4–0.5; transocular width, 1.2–1.3; interocular width, 0.5–0.9; maximum pronotum width, 1.3–1.4; forewing length, 4.4–4.6. Females unknown. Remarks . Metacephalus albocrux shares a very similar aedeagus structure with M. facetus comb. nov. and M. longispinus comb. nov. , all having a very long preatrium and well developed dorsal apodeme, a broad preapical dorsal process on the shaft, and paired apical spiniform elongate processes directed ventrally. Additionally, their styles are bifid, with the mesal ramus longer than the lateral one and curved outward, a very common feature in Metacephalus species, e.g. , also present in M. jenniferae comb. nov.
