Holotype description.

Head and thorax (color). Ground color of anterior dorsum black. Crown ( Figs 2, 3 ) with three large orange spots: one on median portion and another laterally, adjacent to each compound eye. Face ( Fig. 3 ) mostly black with red ocelli; frons ( Fig. 3 ) with pair of yellow maculae on antennal ledges; genae and maxillary plates with pair of large yellowish-brown maculae. Mesonotum ( Fig. 2 ) with pair of tiny yellow marks adjacent to scutoscutellar suture. Forewings ( Fig. 1 ) dark brown with six large scarlet maculae as follows: two mostly on basal half of clavus (connected to each other and transcomissural); one mostly on apical portion of clavus (transcomissural); one on corium opposite claval apex; larger one more basally extending from near costal margin to brachial cell; transverse one on distal half of costal margin extending for approximately half corium width; distal wing margin pale brown. Fore legs with brown area on coxa, trochanter and basal portion of femur, tarsal claws brown, remaining portions mostly yellow; middle legs mostly yellow or reddish-yellow with tarsal claws brown; hind legs mostly brownish-yellow with tibia reddish-yellow, tarsal claws brown.

Male genitalia. Pygofer ( Fig. 7 ), in lateral view, with posterior margin broadly rounded. Subgenital plates ( Fig. 9 ), in ventral view, with basal half subrectangular, distal half triangular, apex narrowly rounded; plates fused to each other along basal half; in lateral view ( Fig. 7 ), extending posteriorly well beyond pygofer apex; surface with many small setae, dorsoapical surface with more developed setae. Styles ( Fig. 10 ), in dorsal view, slender; fork obsolete, slightly directed inward, apex obtuse; style shaft ( Fig. 10 ) with anterior area curved, broadening up to median portion, then narrowing gradually toward apex. Connective simple, in anterior view forming transverse bar, not fused to aedeagal base. Aedeagus ( Fig. 11 ) symmetrical; shaft, in lateral view, long and sinuous, directed dorsally and then anteriorly on basal portion, then strongly curved posterodorsally, remaining area gradually curved ventrally and then directed posteriorly; distal half with pair of small ventral triangular projections followed by concavity; gonopore located dorsally ( Fig. 12 ); apical portion ( Fig. 12 ), in dorsal view, with concavity and acute apex. Membrane IX–X with pair of conspicuous, well sclerotized processes ( Figs 7, 8 ) with apex rounded, broad, directed posteriorly, bearing scattered setae. Anal tube ( Fig. 7 ), in lateral view, with segment X well developed, curved ventrally, with pair of lobes on ventral portion bearing many small setae; anal style with few setae.

Female paratypes (color). Abdominal sternites VI and VII ( Fig. 13 ), in ventral view, brownish-red, pruinose; pygofer ( Fig. 13 ), in ventral view, mostly brown; gonoplacs brown; remaining abdominal venter mostly red (sternite V pruinose). Other color pattern features similar to those of holotype.

Female genitalia (based on one paratype). Abdominal sternite V with small setae concentrated on posterior margin; sternites VI and VII located more internally; sternite VI reduced, projected anteriorly, posterior margin deeply emarginated with small median projection, surface covered by small setae; sternite VII well developed, posterior margin broader and emarginated, surface with pair of longitudinal bands of small setae, with median fovea between bands; laterotergites VI and VII with area on inner portion (lobulate in laterotergite VII) 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 half of shaft; ventroapical region with scale-like processes; dorsoapical and ventroapical margins pseudodentate; apex acute. Second valvulae ( Fig. 45 ), in lateral view, slightly curved dorsally 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). The facial maculae may be dark brown instead of yellow. The forewing maculae may vary in size, shape and color (scarlet or orange).

Etymology. The new species is described in honor of Prof. Dr. Carlos José Einicker Lamas (Museu de Zoologia, Universidade de São Paulo), who has kindly made available for study specimens under his care.
