Elanelajordi sp. nov.
( Figs. 2a View FIGURE , 3 View FIGURE )
Etymology:
This species is named in honor to Dr. Jordi Ribes for hiscontributiontotheknowledgeof theheteropterous Hemiptera of Palaearctic Region. An invariable noun in apposition.
Type material:
HOLOTYPE: ♂, Brazil, Amazonas, Rio Negro , between Ilha Jacari & Airao, 11.x.1971, H. & P. Maas ( RMNH).
PARATYPES: 3 ♂♂ and 4 ♀♀, same data (2 ♂♂, 3 ♀♀ deposited at RMNH; 1 ♂, 1 ♀ deposited at Departamento de Zoologia, Universidade Federal do Rio Grande do Sul, Porto Alegre, Brazil) .
Description:
Color ( Fig. 2a View FIGURE ). Stramineous, with black punctuations irregularly distributed. Head, with punctures forming a «C» laterad of each eye; punctures on the base of head and along the juga; margins of juga outlined by black. Pronotum densely punctured; punctures forming transverse lines on the posterior two thirds; cicatrices lined by punctures. Scutellum uniformly covered by punctures, except for the basal disc, black. Corium uniformly covered by punctures, except for a central callus. Connexivum finely outlined by black. Legs weakly punctured; margins of tibia outlined by black. Ventral abdominal surface densely punctured, completely dark in males and slightly stramineous toward the center, in females.
Head strongly declivent. Jugal apices curved toward clypeus, not surpassing it; margins of juga strongly concave before eyes. Posterior end of each buccula rounded, first rostral segment surpassing the bucculae in 1/3 of its length. First antennal segment stout.
Pronotum trapezoidal; anterolateral margins straight; humeral angles rounded; posterior margin slightly convex, nearly straight. Scutellum apex rounded; shorter than corium. Corium apex rounded, reaching the posteriorfourthof the 6 thconnexivalsegment. Femora unarmed.
Metasternum produced, flat and bifurcate posteriorly, becoming obtusely carinate anteriorly; mesosternum obtusely carinate. Ostiole elliptical, directed posteriorly; peritreme in shape of a spout, extending one half of distance from the lateral margin of metapleuron. Posteriorangleof eachconnexivumacute. Male genitalia ( Figs. 3 View FIGURE a-f). Pygophore ovoid, posterolateral angles slightly developed; lateral thirds of dorsal rim excavated, median third slightly projected posteriorly, margin sinuous ( Fig. 3a View FIGURE ). Inner wall of genitalcuptogetherwithinferiorfoldof ventralrim projected posterolaterad forming a single semi-collar structure embracing the segment X, notched at middle ( Fig. 3b View FIGURE ). Inferior fold of ventral rim of pygophore forming a deep excavation, sinuous at middle. Parameres almost scythe-likein dorsal view, touchingeach other at middle line and covering the base of segment X ( Fig. 3a View FIGURE ). Parameres in lateral view with a median projection bearing hairs ( Fig. 3c View FIGURE ). Surface of segment X concave, apical margin with a deep U-shaped notch ( Fig. 3a View FIGURE ). Phallus very similar to E. hevera exceptlengthof vesicalonger, surpassing phallothecaapertureinalmosthalf thephallotheca length. Conjuntiva also absent ( Figs. 3 View FIGURE d-f).
Femalegenitalia ( Figs. 3 View FIGURE g-h). Apicalmarginof segment VII weakly concave, almost straight at gonocoxites 8. Spiracles present on laterotergites 8 ( Fig. 3g View FIGURE ). Posterior margins of laterotergites 8 with a short projection ( Fig. 3g View FIGURE ). Posteriormarginsof gonocoxites 8 slightly sinuate, sutural angles rounded, divergent somewhat projected covering the middle of gonocoxites 9; sutural margins parallel ( Fig. 3g View FIGURE ). Laterotergites 9 not lanceolate, apical margins triangular, clearly surpassing the band uniting ventrally the laterotergites 8 ( Fig. 3g View FIGURE ). Posteriormarginof gonocoxites 9 slightlyconcave ( Figs. 3 View FIGURE g-h). Ectodermical genital ducts very similar to E. hevera but the capsula seminalis is oblong, lacking a digitiform process ( Fig. 3h View FIGURE ). Ductusreceptaculi after vesicular area very long, clearly surpassing the middle of this area ( Fig. 3h View FIGURE ). Vesicular area more sclerotized at base ( Fig. 3h View FIGURE ). Chitinellipsen present as in E. hevera inspiteof thementioninGrazia (1989) thatthechitinellipsenwereabsent. Thickeningof vaginalintima conical, directed ventrally (in E. hevera is directed anteriorly) ( Fig. 3h View FIGURE ).

Differential diagnosis:
Elanela jordi sp. nov. differs from the other two species of the genus by being darker in color. Males are easily distinguished by the ventral abdominal surface uniformly colored, apicalmarginof segment XU-shaped andshapeof theparamereswhicharescythe-likein dorsal view. Females have the gonocoxites 8 covering gonocoxites 9, posterior margins sinuous; laterotergites 9 clearly surpassing the band uniting dorsally the laterotergites 8.
