Coelindroma tuberculata sp. nov.

Figs 12–22 , 24, 27

Diagnosis. Head, in frontal view, with two small black spots on the upper sides of the frons; in lateral view, with evident preapical tubercle on crown ( Figs. 13–14 ); pygofer, in lateral view, trapezoidal-shaped ( Fig. 16 ); subgenital plates, in ventral view, not fused at apical fifth, with pair of macrosetae ( Fig. 17 ); style, in lateral view, with apical third abruptly upturned, preapical lobe well developed, and apex strongly curved ventrally ( Fig. 19 ); aedeagus with pair of short apical convergent processes ( Fig. 21 ).

Measurements (mm). Male holotype: total length 6.25; crown median length 0.94; transocular width 1.15; interocular width 0.61; frons basal width 0.58; frons length 1.06; pronotum median length 0.62; width between humeri 1.42; mesonotum median length 0.97; mesonotum maximum width 1.07; forewing length 4.69; forewing maximum width.

General color. Body pale-yellow with orange maculae ( Figs 24–27 ). Crown pale-yellow, with large black median macula on anterior half extending to the upper sides of the frons, posterior half and two lateral longitudinal bands extending to antennal ledge, orange; frons, in frontal view, with orange V-shaped maculae; antennal flagellum light-brown ( Figs 12–14 ). Pronotum pale-yellow; median longitudinal broad band, extending from anterior to posterior margin, emarginated laterally, two smaller longitudinal bands placed on anterior half of lateral margins, orange. Mesonotum with pair of large subtriangular maculae on basal half, and apex, orange ( Fig. 12 ). Forewings hyaline with inner margin of apical third dark-brown ( Fig. 15 ). Hindwings pale-yellow hyaline with yellow venation. Legs pale-yellow ( Fig. 27 ).

Description. Head, in lateral view, with evident preapical tubercle on crown ( Fig. 14 ). Male pygofer, in lateral view, trapezoidal-shaped; apex rounded; ventral margin produced ventrally with apex acute and sclerotized (= ventral hook in Kramer, 1967) ( Fig. 16 ). Subgenital plates, in ventral view, abruptly constricted at apical half; fused except at apical fifth; with pair of macrosetae ( Fig. 17 ); in lateral view, as long as the pygofer; curved and strongly concave dorsally; with dorsal margin abruptly descending towards apex; without dorsal preapical tooth ( Fig. 18 ). Styles not attaining posteriorly apex of connective; in lateral view, slender, with apical third abruptly upturned; preapical lobe distinct; apex sclerotized, strongly curved ventrally, with some preapical setae ( Fig. 19 ). Connective, in dorsal view, Y-shaped; about two-thirds the length of styles; articulated to the basis of the aedeagus ( Fig. 20 ). Aedeagus, in lateral and dorsal view, slender and elongate, with apical third curved anterodorsally; slightly enlarged preapically ( Fig. 22 ); in posterior view, with pair of short apical processes with apices acute and convergent ( Fig. 21 ); preatrium shorter than the shaft, dorsal apodeme reduced ( Fig. 22 ). Anal tube without processes ( Fig. 16 ). Female unknown.

Geographical distribution. Brazil (Amazonas).

Specimens examined. Male holotype (INPA), with following labels: “ BRASIL, Amazonas, Ipixuna, Rio\ Gregório, Com. Lago Grande\ 07°10’11.7’’S – 71°49’10.3’’W \ 23.v.2011, 01:00–04:00h; Arm. Luminosa baixa\ J.A. Rafael, J. T. Câmara, R. F.\ Silva, A. Somavilla, C.\ Gonçalves & A. Agudelo leg.; Holótipo\ Coelindroma tuberculata \ Gonçalves, Marques-Costa & Ale-Rocha\ 2011 ”.

Holotype condition. Thorax ventrally glued to triangle by right side; antennae, forewings, hindwings, and legs in perfect state; abdomen dissected.

Etymology. The species name refers to the tubercle on the crown.

Comments. Coelindroma tuberculata sp. nov. resembles C. fungosa ( Figs 25, 28 ) by the trapezoidal-shape of pygofer; styles with evident preapical lobe; and elongate aedeagus. However, the color pattern ( Figs 24, 27 ), presence of distinct preapical tubercle on the crown, and short apical processes on the aedeagus allow C. tuberculata to be easily distinguished from C. fungosa .
