Placoscopana Gonçalves, Marques-Costa & Ale-Rocha, 2012

( Figs 4A–L ; 5G, H )

Placoscopana Gonçalves, Marques-Costa & Ale-Rocha 2012: 483 (description).

Type-species: Placoscopana nigrilinea Gonçalves, Marques-Costa & Ale-Rocha, 2012 , by original designation.

Diagnosis. Crown ( Figs 4A ; 5G, H ) short, median length distinctly less than interocular width; surface slightly concave; anterior margin rounded; lateral margins, adjacent to the eyes, sinuous, elevated, and carinate; coronal suture distinct, evident on basal two-thirds. Ocellus ( Figs 4B, C ) positioned on anterior margin of head. Frontogenal suture ( Fig. 4B ) reaching ocelli. Antennal ledge ( Fig. 4B ) developed, oblique, and carinate. Gena ( Fig. 4B ) not fully covering episternum. Crown-face transition ( Figs 4C ; 5H ) acutely rounded, with a transverse carina. Pronotum ( Fig. 4A ; 5G ) with posterior margin sharply excavated. Forewing ( Figs 4D ; 5G, H ) with three anteapical and four apical cells, all approximately rectangular, base of second apical cell proximal to base of third cell, base of fourth cell proximal to bases of second and third cells; venation obscure, except apically. Hind wing with veins R 4+5 and M 1+2 preapically convergent, fused at apex, forming single vein. Male pygofer ( Fig. 4E, F ) shorter than subgenital plates, dorsal margin sloped posteroventrad; bearing ventrocaudal process. Anal tube ( Fig. 4E, F ) without process. Subgenital plates ( Fig. 4E, G, H ) fused at basal portion only; relatively long, slender and constricted near midlength in ventral view; apex with dorsal tooth. Connective ( Fig. 4I ) Y-shaped, stem longer than arms. Style ( Fig. 4I, J ) with small sclerotized tooth beneath apical hook. Aedeagus ( Fig. 4K, L ) with dorsal apodeme longer than preatrium; base of shaft with a rounded ventral protuberance; shaft long, curved dorsad; gonopore apical.

Distribution. Brazil [new record]: Amazonas, Roraima; Ecuador: Orellana.

Remarks. Gonçalves et al. (2012) noted the similarity between the external morphology of Placoscopana and Coronalidia Marques-Costa & Cavichioli, 2007 . However, a phylogenetic analysis of Neocoelidiinae based on morphological and molecular data (Gonçalves et al. unpublished) recovered Placoscopana in a well-supported clade with Biza Walker, 1858 , Megacoelidia Kramer & Linnavuori, 1959 , and Aglenita Spinola, 1850 . According to this analysis, these genera share the following characteristics: 1) crown short, median length shorter than interocular width; 2) crown surface concave, except in Aglenita ; 3) head with crown-face transition with complete and well-developed carina; 4) head with lateral margins carinate; 5) ocellus positioned on anterior margin of crown; 6) forewing with elongated apical cells; 7) metatibia, with posterodorsal row bearing 3–4 smaller intercalary setae, except in Megacoelidia ; 8) subgenital plates fused at basal portion only; and 9) aedeagus with shaft curved anterad.
