( Figure 3A–I View Figure 3 )

Description

Length

Male holotype, 5.5 mm.

Head and thorax

General ground colour pale brown. Crown ( Figure 3A View Figure 3 ) shorter medially, widened next to inner margin of eyes; with pair of slender foveae equally distant between median area and eyes, each one with adjacent dark brown macula; with brown stripe on median portion extending to superior area of face. Face ( Figure 3B View Figure 3 ) with area adjacent to ocelli with pair of dark brown maculae. Frons with several irregular dark brown maculae forming pair of lateral rows; lateral portions dark brown. Clypeus dark brown on lower portion. Pronotum ( Figure 3A View Figure 3 ) anterior portion with pair of dark brown maculae located on slender depressions, lateral portions with pair of triangular dark brown marks and posterior margin with dark brown median line almost reaching anterior margin of pronotum. Mesoscutum with laterobasal triangular maculae and pair of small rounded marks at central portion; mesoscutellum with pair of brown maculae at laterobasal portions.

Genitalia

Pygofer ( Figure 3C View Figure 3 ), in lateral view, L-shaped; ventral L projection elongate and with truncate apex, directed dorsally. Subgenital plates ( Figure 3D View Figure 3 ), in ventral view, totally fused to each other, except for most apical area; proximal margin round, outer margins almost straight up to strong constriction on apical third, apical portion with pair of fused round lobes with scattered long setae. Styles ( Figure 3E View Figure 3 ), in dorsal view, slender; fork absent; shaft with elongate lateral process on outer margin for attachment of subgenital plates and well-developed projection on inner margin for articulation with connective; subapical area with few setae; apex truncate and heavily sclerotized. Connective ( Figure 3F View Figure 3 ) well developed and heavily sclerotized; Y-shaped in dorsal view, not fused with aedeagal base. Aedeagus ( Figure 3G View Figure 3 ) simple, symmetrical; with basal area larger on median region; shaft ( Figure 3G, H View Figure 3 ) strongly curved dorsally, forming right angle with basal area, bearing several scale-like projections; subapical portion with few spiniform processes; apex similar to a bird’s beak with ventral margin serrated. Anal tube, in lateral view, with segment X well developed, globose, bearing pair of large hook-shaped processes ( Figure 3I View Figure 3 ) directed ventrally.

Etymology

The new species is described in honour of Geert Goemans (Department of Ecology and Evolutionary Biology, University of Connecticut, Storrs, CT, USA), who has published fine contributions on the Neotropical Fulgoridae .

Type material

Holotype, male: Brazil, Pará State.“Brasil/PA – Obidos \ III/1958 \ Zirpen col.” ( MZSP).

Remarks

Euragallia goemansi sp. nov. is included in the magnicauda complex. The species from this group that share similar processes on the segment X with the new species are E. magnicauda and E. attenuata . Among the species included in the magnicauda complex, E. magnificentia , E. puntarenensis and E. magnicauda have, respectively, the pygofer, subgenital plates and aedeagus most similar to that of E. goemansi . Although E. nervata is positioned in another complex, the drawing of its aedeagus provided by Linnavuori and DeLong (1979a) is very similar to that of E. goemansi . Nevertheless, the original drawing by Oman (1934) does not show the similarities observed between the two species. The new species can be separated from these and others of the genus by the following features: (1) pygofer ( Figure 3C View Figure 3 ), in lateral view, L-shaped; (2) subgenital plates ( Figure 3D View Figure 3 ), in ventral view, with apex round, similar to a pair of circles almost fused; (3) shaft of aedeagus ( Figure 3G, H View Figure 3 ) bearing several scale-like projections; subapical portion with few spiniform processes; (4) apex of aedeagus ( Figure 3G View Figure 3 ), in lateral view, similar to a bird’s beak with ventral margin serrated; (5) segment X with pair of large hook-shaped processes ( Figure 3I View Figure 3 ), directed ventrally.
