Coelho, Luci Boa Nova, Da-Silva, Elidiomar Ribeiro & Ferreira, Paulo Sérgio Fiuza, 2016, Two new species of genus Joruma McAtee (Hemiptera: Cicadellidae: Typhlocybinae) from Viçosa, Minas Gerais State, Brazil, Zootaxa 4162 (2), pp. 304-312 : 305-308

Joruma abernardesi sp.nov.

( Figs 1 , 3–21 )

Length 3.7–3.9 mm. General color green ( Fig. 1 ). Head with anterior margin moderately pronounced; crown ochraceus with medial rounded brown spot on anterior margin and oval brown spot obliquely located on each side of median line; ocelli black surrounded by narrow brown area; eyes brown; face slightly rounded, somewhat longer than wider, pale yellow in inferior half and brown in superior half. Pronotum ochraceus with extensive olive band connecting posterolateral angles, near ochraceus posterior margin; length of pronotum approximately 1.5 times length of crown; maximum width of pronotum equal or so the length of head. Scutellum green with ochraceus margins, apex yellow. Legs pale yellow.

Forewings ( Fig. 3 ) olive, costal cell brown, apex of apical region and apical cells translucent brown; veins yellow, except for R, brown; narrow yellow-white irregular band limiting apical area, dark brown, of brachial cell; Hind wings ( Fig. 4 ) brown, translucent, veins brown, shiny, except vein MP2 transparent.

Male genitalia. Subgenital plate ( Fig. 5 ) long with tapered apical third, slightly curved in dorsal region, with many external folds, apex rounded; three macrosetae near outer margin and two small and robust setae in median area of apical third. Pygofer ( Fig. 6 ) triangular with posterodorsal area pronounced without distinct posterior margin, with small and delicate setae sparsely distributed in dorsal and posterior areas; anal hook robust, well developed, with two divergent terminals branches; posterior branch sharp with apex acute, bent to posterior region and exceeding margin of pygofer; anterior branch more robust, with longitudinal folds, apex thick, striate, reaching ventral margin of pygofer. Stylus ( Fig. 7 ) slender, apical region curved and apex acute; posterior arm with small denticles on preapical external curvature and long seta on inner curvature. Connective Y shaped, but apparently H shaped, middle part of stem inconspicuously membranous, side arms and main branch nearly same size ( Fig. 8 ). Aedeagus ( Figs 9–10 ) with preatrium short, dorsal apodeme H shaped with window like space in middle, longer and divergent upper arms; stem laterally compressed, ventral side with pair of narrow median lamellae extending from base to apex of stem; gonopore ventroapical, broad.

Female genitalia. Sternite VII ( Figs 12–13 ) produced in two median lobes with rounded apices, formed by median cleft with small tooth on each side. Pygofer ( Fig. 11 ) elongated, posterior margin rounded; ovipositor exceeding far beyond apical margin of pygofer; valvulae long and narrow. Valvula I ( Figs 14 , 18 ) curved upwards, apex acute; dorsal margin of apical 1/4 finely strigate, with tiny roundish teeth; ventral apical margin with tiny teeth, and acute teeth on ventral fold forming smooth crenulations. Valvulae II ( Figs 15–16 , 19–20 ) slightly sinuous, downturned apically; ventral margin strigate, more so on left blade; right valvula II with dorsal margin serrate, teeth slightly elevated anteriorly and truncated posteriorly, each tooth formed by roundish denticles; left valvula II slightly serrated, with roundish denticles. Valvula III ( Figs 17 , 21 ) with apex narrow and roundish, tiny setae on apical area mixed with higher and sparse ones; sets having 1 to 4 micro setae in central surface.

Holotype. 1 ♂, Mata do Paraíso , Viçosa , Minas Geais, Brasil, 05/iii/1987, P.S.F. Ferreira [ DZRJ]. Paratypes: same place and collector , 1 ♂ (23/ix/1986), 1 ♀ (22/iii/1988), 1 ♂ (11/v/1988) [DZRJ]; 1 ♀ (22/iv/1987), 1 ♂ (12/ vi/1986), 1 ♀ (13/iv/1988) [UFVB].

Etymology. The name is given in honor to Artur da Silva Bernardes (1875–1955), president of Brazil between 1922 and 1926, who protected the country's natural resources. Along with P.H. Rohlfs, he founded the "Escola Superior de Agricultura e Veterinária" (College of Agriculture and Veterinary), which later became the "Universidade Federal de Viçosa " (Federal University of Viçosa ).

Comments. The general color of Joruma abernardesi sp.nov. resembles the pattern described for J. ascripta , but It can be easily distinguished by the apex of vein CuA confluent with the apical region of M3+4. J. proxima , a species related to J. ascripta by McAtee (1926), has apex of forewing vein CuA similar to that of Joruma abernardesi sp.nov., but differs in color pattern. The anal hook of J. abernardesi sp.nov., robust with apex divided into two branches resembles that of J. phrolfsi sp.nov., but differs by the divergent branches and the general morphology. The anal hook and stylus with curved apex can distinguish J. abernardesi sp.nov. from any other species of genus Joruma .
