Orthorapha (Lepyronoxia) oculata sp. nov.

Etymology. oculata (adjective), from the Latin for “having eyes.”

Diagnosis. Tegmen with large, round ivory spot near base of costa ( Fig. 35 H); thecal tip diamond-shaped ( Fig. 11 B).

Description. Tan to sordid greenish with face and costal margins of tegmina dark brown to black, with round ivory spot near base of costa larger than yellow to ivory spots on midlength and near apex of costa and another on apex of central discal cell ( Fig. 35 H); pale lines on crown (as in O. decorata ) weakly marked; irregular pale spots also on sides of pronotum; veins on tegminal tips pale. Head well produced, as long as median length of pronotum; frons inflated, rounded in dorsal aspect, receding in profile; crown declivous; frons scarcely lower than clypellus at maximum expansion; head as wide as pronotum; lateral margins of pronotum much shorter than eye; tegmina densely covered with small pits, twice as long as broad, with veins weakly carinate; hind wings as in Orthorapha concinna ( Fig. 2 D) but with apical cell shorter, crossvein r-m situated more distad as in O. obliqua ( Fig. 2 C). Theca shaft sinuate in lateral aspect, in caudal aspect strongly broadened and with angular processes at midlength, tip spatulate, membranous, with broad gonopore ( Fig. 11 A–B). Length: male 6.0– 6.9 mm, female 7.4 mm. Width across head or pronotum: male 2.4 mm, female 2.7 mm.

Type. Holotype male: BRAZIL: São Paulo: Boraceia, 16–18 Nov. 1970 (J. & M. Sedlacek), in BPBM. Paratypes: 5 males, 1 female, same data; 3 males and 1 female in BPBM; 2 males No. 23949 in CNCI.

Orthorapha (Lepyronoxia) quadrimaculata (Lallemand) , comb.nov.

Lepyronia quadrimaculata Lallemand, 1938: 349 .

Balsana quadrimaculata: Metcalf & Wade 1962: 192 .

Diagnosis. Resembling O. oculata ( Fig. 35 H), but with large costal pale spot irregular in shape, broad wing tips without pale preapical spots, and theca with digitate tip contrasting strongly with lamellate shaft ( Fig. 16 A).

Description. Blackish brown, boldly marked with large ivory spot near base of costa, and smaller yellow to ivory spots forming W-shaped figure on apex of head (as in O. frontalis ), paler brown to ivory on trochanters and leg joints, sometimes tan to greenish brown on a variable amount of dorsum, at most with entire dorsum pale except for outer halves of tegmina, at other times with pale triangular area more or less fused with two sock-shaped areas (as in O. decorata ); lines on crown (as in O. decorata ) and irregular spots on sides of and fore margin of pronotum and near tip of tegmen along with a few pale vein tips. Head well produced but shorter than median length of pronotum; frons well inflated, rounded in dorsal aspect, receding in profile; crown weakly declivous; frons above clypellus at maximum expansion; head slightly narrower than pronotum; lateral margins of pronotum much shorter than eye; tegmina densely covered with small pits, 1.7 × as long as broad, with veins weakly raised, carinate only at tips; hind wings as in Orthorapha concinna ( Fig. 2 D). Style widened near midlength, then abruptly narrowed, digitate with small spine on outer margin just before tip. Theca shaft very wide at midlength in lateral aspect, strongly tapered to digitate process above gonopore. Length: male 4.6–4.8 mm, female 5.3–5.5 mm. Width across pronotum: male 1.8 mm, female 2.0 mm.

Type. Holotype male: BRAZIL: Rio [de Janeiro]—Rezende, Feb. 1924 (F.X. Williams); not examined. Paratypes: 1 male, 1 female, same data; in BMNH. Four additional males from the same series (probably not type material) labeled “Clastophora [sic] sp. Det. B. Uvarov 1937" in BPBM.

Additional Material. BRAZIL: 2 males, 2 females from: Minas Gerais —Delfim Moreira 1100m [ASL], Feb. 1972 (F.M. Oliviera) BM 1972–541; 1 female, [Rio de Janeiro]—Itatiaya (Lahtivirta); 1 female, [ Brazil or Uruguay?]—Constancia, Jan. 1857 (H. Clark); in BMNH.
