Chromagallia lanceolata Gonçalves, Mejdalani View in CoL et Costa sp. nov.

( Figs 23–29 View FIGURES 23 – 29. C , 47 View FIGURES 41 – 48 )

Length. Male holotype, 5.5mm; male paratypes, 5.2–5.6mm; female paratypes, 5.5–5.6mm.

Holotype description.

Head and thorax (color). Ground color of anterior dorsum mostly black. Crown with three large orange spots: one on median portion and another laterally, adjacent to each compound eye. Face mostly black with red ocelli; frons with pair of yellowish-brown maculae on antennal ledges; genae and maxillary plates with pair of yellowish-brown maculae. Posterior margin of pronotum narrowly marked with brown. Mesonotum with pair of tiny yellow marks adjacent to scutoscutellar suture; scutellum brown laterally. Forewings with basal 3/4 mostly red-orange; with sinuous, oblique and transcomissural dark brown stripe originating on basal portion of corium, crossing claval sulcus and attaining inner claval margin (where it is broader); median portion of corium with irregular, sinuous dark brown stripe extending from costal margin to claval sulcus (running adjacent to posterior portion of claval sulcus); distal 1/4 of wing mostly dark brown with pale brown area adjacent to posterior margin. Fore legs with brown maculae on coxa, trochanter, and basal portion of femur, tarsal claws brown, remaining portions mostly yellow; middle and hind legs mostly reddish-yellow with tarsal claws dark brown.

Male genitalia. Pygofer ( Fig. 23 View FIGURES 23 – 29. C ), in lateral view, short with posterior margin slightly convex; posteroventral margin with process directed inward, bearing few setae; process, in caudal view, subtriangular. Subgenital plates ( Fig. 24 View FIGURES 23 – 29. C ), in ventral view, fused to each other up to middle portion; basal margin and median basal portion weekly sclerotized; apical portion distinctly broadened; surface with scattered setae; in lateral view ( Fig. 23 View FIGURES 23 – 29. C ), plates extending posteriorly well beyond pygofer apex; median portion of lateral margins projected dorsally. Styles ( Fig. 25 View FIGURES 23 – 29. C ), in dorsal view, slender, fork well developed, curved inwards. Connective simple, in anterior view forming transverse bar, not fused with aedeagal base. Aedeagus ( Fig. 26 View FIGURES 23 – 29. C ) symmetrical; shaft, in lateral view, very long, directed dorsally and then anteriorly on basal portion, then strongly curved posterodorsally, remaining area gradually curved ventrally and then directed posteriorly; first curved portion distinctly lobed; apex ( Fig. 27 View FIGURES 23 – 29. C ), in dorsal view, lance-shaped. Membrane IX–X with pair of conspicuous, well sclerotized processes expanded apically and bearing setae ( Fig. 28 View FIGURES 23 – 29. C ). Anal tube ( Fig. 23 View FIGURES 23 – 29. C ), in lateral view, with segment X well developed, projected ventrally, with pair of lobes on ventral portion bearing many small setae; anal style with few setae.

Female paratypes (color). Abdomen ( Fig. 29 View FIGURES 23 – 29. C ), in ventral view, with distal portion mostly brown; remaining area red. Other color pattern features similar to those of the holotype.

Female genitalia (based on one paratype). Abdominal sternite V with small setae concentrated on posterior half; surface of sternite VI covered by small setae; sternite VII located more internally, well developed, posterior margin with deep broad emargination, surface covered by small setae; laterotergites VII with lobulate area on inner portion bearing small setae. Base of ovipositor exposed. First valvulae, in lateral view, dorsally curved from base; ventral interlocking device distinct, located on basiventral portion of shaft; dorsolateral surface with reticulate sculptured area formed by oblique rows of scale-like processes on distal 2/ 3 of shaft; ventroapical region with scale-like processes; dorsoapical and ventroapical margins pseudodentate; apex acute. Second valvulae ( Fig. 47 View FIGURES 41 – 48 ), in lateral view, slightly dorsally curved from base, with broadest point on apical third; with dorsal hyaline area on median portion; inconspicuous dorsal prominence present; teeth mostly subtriangular, not bearing denticles, positioned on distal half of dorsal margin (just behind dorsal hyaline area); shaft apex subacute. Gonoplacs, in lateral view, with proximal half broadening abruptly toward median portion; apex narrowly rounded; surface with tiny spiniform processes and setae on apical portion and extending anteriorly along ventral margin.

Intraspecific variation (based on all male and female paratypes). Ocelli vary from pale yellow to red; facial maculae may vary in size and tonality. Forewing maculae may vary in size, shape and color (from redorange to scarlet).

Etymology. The species epithet, lanceolata , refers to the lance-shaped aedeagal apex, which is diagnostic of the new species.
