( Figs. 3 and 4B )

Diagnosis

The new species can be recognized and separated from its congeners by the presence of one very conspicuous white spot (outlined in gold) on the first bifurcation of CuA of each tegmen, and by the lateral carinae of pronotum outlined in light and dark yellow.

Description

Holotype female ( Figs. 3 and 4B ).

Head ( Fig. 3B ): vertex and occiput green, with one yellow line from behind the eyes towards pronotum; fastigium bilobate, lobes barely distinct; carinae of fastigium of the vertex without exceeding its length; frons light green with light yellow stains, trapezoidal; frons triangular, with one large lemon green ocellus; clypeus light yellow, labrum white; gena yellowish, with one pale yellow strip from eye to base of occiput.

Thorax: pronotal disc green ( Fig. 3C ); lateral carinae outlined in light yellow, with a slender dark yellow border ( Fig. 3C ); anterior margin of carinae concave, posterior margin convex; prozone with a sulcus extending to lateral lobes; lateral lobes green, higher than long ( Fig. 3B ); lateral suture not reaching half of the height of pronotal lobe; coxal spine prominent; tegmina ( Fig. 3A and 4B ) pointed at apex, yellowish green, with one oval white spot outlined in golden on the first CuA bifurcation ( Fig. 3D ); MP vein starting before the middle of tegmina, with one ramification before the middle of tegmina, and ending before tegmina apex; first branch of CuA vein diverging in the white spot, second branch near the first closed cell of MP and CuA; one closed cell between CuA and MP; two closed cells between branches of Rs; one closed cell between the main branch of MP and MA; nine branches leaving R in direction to subcostal border; CuP vein yellow, dentate in proximal region; right tegmen with just one stridulatory vein, with 10 teeth ( Fig. 3E ); mesosternum triangular, mesosternal lobes triangular and long, without reaching distal area ( Fig. 3F ); metasternum triangular, with large and rounded lobes ( Fig. 3F ).

Abdomen: overall coloration aquamarine; subgenital plate triangular, with an apex bifid that forms two square processes, originating from a large keel that begins on plate base; ovipositor green at base, becoming brown towards apex, higher than long, upcurved in ca. 90º ( Fig. 3G ); dorsal valves dilated at the base; ventral valves slender at the base, becoming larger after the curvature; teeth light brown, beginning at the apical third of the dorsal valves and at the fifth part of ventral valves; basal plate almost triangular.

Etymology

In the Tupi mythology, Jaci is the moon and also the mother of fruits and vegetables (see Lima and Moreira, 2005). The name refers to the remarkable white spot found in each tegmen that resembles the full moon. Noun in apposition.

Remarks

Phylloptera jaci sp. nov. is closely related to Phylloptera picta , and the main differences between them are the following: the strips behind the eyes, that are black inP. picta and yellow in the new species; the lateral carinae that are outlined in different colours, dark yellow/ yellow in P. jaci sp. nov. and black/ yellow in P. picta ; the single spot on the bifurcation of CuA, black in P. picta and white in P. jaci sp. nov.; the number of closed cells between the branches of MP also varies, two in the new species and four in Phylloptera picta ; the number of closed cells between the main branch of MP and MA also varies, one in Phylloptera jaci sp. nov. and three in Phylloptera picta ; even regarding venation of tegmina, nine branches depart from R in the new species and fifteen in Phylloptera picta ; finally, the colour of the apex of the femur that differs from body coloration in Phyllotera picta and not in the new species. The decision of comparing the tegmina of the holotype female of P. jaci sp. nov. and of the lectotype male of P. picta is supported by the observation that the tegmina of males and females of the same species in other Phyllopterini are quite similar (Fianco, pers. obs.), which is confirmed when the tegmina of the lectotype and paralectotype of P. picta are compared.
