Joruma abernardesi


Joruma abernardesi  sp.nov.

( Figs 1View FIGURE 1, 3–21View FIGURES 3 – 10View FIGURES 11 – 17View FIGURES 18 – 21)

Length 3.7–3.9 mm. General color green ( Fig. 1View FIGURE 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. 3View FIGURES 3 – 10) 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. 4View FIGURES 3 – 10) brown, translucent, veins brown, shiny, except vein MP2 transparent.

Male genitalia. Subgenital plate ( Fig. 5View FIGURES 3 – 10) 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. 6View FIGURES 3 – 10) 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. 7View FIGURES 3 – 10) 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. 8View FIGURES 3 – 10). Aedeagus ( Figs 9–10View FIGURES 3 – 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 12–13View FIGURES 11 – 17) produced in two median lobes with rounded apices, formed by median cleft with small tooth on each side. Pygofer ( Fig. 11View FIGURES 11 – 17) elongated, posterior margin rounded; ovipositor exceeding far beyond apical margin of pygofer; valvulae long and narrow. Valvula I ( Figs 14View FIGURES 11 – 17, 18View FIGURES 18 – 21) 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 15–16View FIGURES 11 – 17, 19–20View FIGURES 18 – 21) 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 17View FIGURES 11 – 17, 21View FIGURES 18 – 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  .
