description: Rosalydia inpa gen. et sp. nov.
Figs 3–4, 16–25
Diagnosis. Pygofer, in lateral view (Fig. 18), with ventral margin widely excavated with apical rounded lobe, dorsoapical margin expanded dorsoposteriorly and curved ventrally at apex, inner caudal process (Figs 18–19) adjacent to posterior margin and surpassing the ventral margin, apical portion of process with several rugosity; subgenital plates, in ventral view (Fig. 21), subtriangular, broad in basal half and distinctly narrowed in apical half, apical two-thirds of inner margin with about 30 teeth approximately regular in size; aedeagus (Figs 24–25) with shaft compressed on apical third, subapical processes very short, spine-like.
Measurements (mm). Male holotype: total length 7.6.
Coloration. Body yellow (Figs 3–4), green in life. Crown (Fig. 3) with four orange stripes, three longitudinal and one transverse forming E-shaped macula, longitudinal strips extending to mesonotum. Face (Fig. 16) with frons orange. Forewing (Fig. 17) semi-hyaline, anal margin and adjacent portion dark yellow.
External morphology. External morphological characters as in generic description.
Male terminalia. Pygofer, in lateral view (Fig. 18), subtrapezoidal, longer than high; ventral margin widely excavated, apical portion, slightly expanded, forming rounded lobe; dorsoapical margin expanded dorsoposteriorly, curved ventrally at apex; few short setae scattered dorsoapically; inner caudal process adjacent to posterior margin and surpassing ventral margin, in posterior view (Fig. 19), process approximately straight and expanded basally, apex rugose. Subgenital plates, in lateral view (Fig. 20) approximately 6.5 times longer than maximum height; not tapered towards apex; in ventral view (Fig. 21), each plate subtriangular, broad in basal half and distinctly narrowed in apical half; apical two-thirds of inner margin with about 30 teeth approximately regular in size; apex subacute. Connective (Fig. 22) approximately two-thirds length of style. Aedeagus, in lateral view (Fig. 24), tubular on basal two-thirds and flattened dorsoventrally on apical third; in caudal view (Fig. 25), shaft compressed on apical third; subapical processes very short; apex rounded. Anal tube (Fig. 18) with tergite X four times longer than wide.
Female terminalia. Female unknown.
Material examined. Holotype ♂: “ Brasil, AM, Ipixuna, Rio \ Gregório, Com. Lago grande\ 07°10’11.7”S – 70°49’10.3”W \ 17-22.v.2011, Arm. Luminosa, R.\ Andreazze & D.M. Takiya leg” (INPA).
Etymology. Species named in honor of the Instituto Nacional de Pesquisas da Amazônia (INPA), a major contributor to the study of tropical biology with important contributions to studies of insect biodiversity over the past several decades, which has greatly contributed to the training in entomology provided to the authors of this paper.
Remarks. Rosalydia inpa gen. et sp. nov. resembles R. alvarengai gen. et sp. nov. by the long length of caudal process of pygofer (Figs 8, 18); subgenital plates with all teeth of inner margin approximately the same size (Figs 11, 21); and aedeagus unexpanded on basal third (Figs 14, 24). Also, R. inpa gen. et sp. nov. resembles R. xavieri gen. et sp. nov. by pygofer with dorsoapical margin expanded dorsoposteriorly and curved ventrally at apex (Figs 18, 28). However, R. inpa gen. et sp. nov. is mainly distinguished from other species by ventral margin of pygofer widely excavated with apical rounded lobe (Fig. 18).
