Polana (Declivella) maculosa  sp. nov.

( Figs 10–18 View Figure , 44, 45 View Figure )

Diagnosis. Male pygofer ( Fig. 13 View Figure ) with dorsoapical, rounded sclerotized small process; style ( Figs 15, 16 View Figure ) broad medially and with ventral margin serrate; aedeagal shaft ( Figs 17, 18 View Figure ) with two pairs of long and narrow lateral processes, one apical and one preapical.

Description (male holotype). Length 10.9 mm. Head ( Fig. 44 View Figure ), in dorsal view, short, just slightly produced anteriorly; slightly narrower than pronotum; transocular width about five-sixths of humeral width of pronotum. Crown ( Fig. 44 View Figure ) with median length approximately one-third of interocular width; anterior and posterior margins approximately parallel; surface slightly depressed on outer side of ocelli; texture with numerous punctures and transverse superficial striations; coronal suture indistinct. Ocellus large; equidistant between anterior and posterior margins of crown; closer to adjacent compound eye than to midline. Transition between crown and face ( Fig. 45 View Figure ) indistinct and rounded. Face ( Fig. 10 View Figure ) wider than high. Frontogenal suture not extending upwards beyond antennal ledge. Antennal ledge, in frontal view, approximately transverse; extending inwardly beyond frontogenal suture. Frons ( Fig. 10 View Figure ) slightly swollen; texture with transversal superficial striations; lateral margin separated from eye by distance slightly larger than maximum width of clypeus. Epistomal suture distinct, complete. Clypeus ( Fig. 10 View Figure ) higher than wide, expanded apically.

Pronotum, in dorsal view ( Fig. 44 View Figure ), with lateral margins convergent anteriorly; posterior margin approximately straight; disk transversely striated and covered by numerous dark punctures; in lateral view ( Fig. 45 View Figure ), strongly declivous anteriorly. Forewing ( Fig. 11 View Figure ) subhyaline; venation distinct, not reticulated; apex rounded; appendix very narrow, extending only to second apical cell. Forefemur with AD, AM, and PD rows reduced and poorly defined, AD1, AM1, and PD1 indistinct; AV row restricted to basal half, formed by eight or nine setae, increasing in length towards apex, slightly spaced apart, seta AV1 indistinct; IC row formed by slightly arched comb of fine setae beginning at distal half of femur; PV row formed by three basal setae and one apical seta. Hind leg with femoral setal formula 2:2:1; tibial AD row with long spiniform setae with prominent bases, without intercalary microsetae; first tarsomere with two parallel rows of setae on ventral surface, pecten with seven platellae medially; apex of second tarsomere with four apical platellae.

Coloration. Mottled with brown ( Figs 44, 45 View Figure ). Crown ( Fig. 44 View Figure ) with dark brown to black median line, extending from anterior to posterior margin, faint medially; with black macula posterior to each ocellus. Frons ( Fig. 10 View Figure ) with nine pairs of aligned black markings over muscle impressions. Lorum ( Fig. 10 View Figure ) with large brown marking adjacent to clypeus. Pronotum ( Fig. 44 View Figure ) mottled with dark brown on anterior half; disk with numerous dark brown punctures. Mesonotum ( Fig. 44 View Figure ) with basolateral angles dark brown; with pair of elongate, oblique brown marks anterior to scutellar suture. Forewing ( Fig. 11 View Figure ) covered by numerous brown maculae throughout surface. Legs ( Fig. 45 View Figure ) mostly pale brown with yellow areas and scattered dark brown maculae; tarsi dark brown.

Male terminalia. Sternite VIII ( Fig. 12 View Figure ) wider than long, median length approximately three-fourths of maximum width; posterolateral corners broadly rounded; posterior margin slightly excavated medially. Pygofer ( Fig. 13 View Figure ) approximately as long as high; dorsal margin with small, preapical sclerotized bulbiform process; apex broadly rounded and slightly sclerotized; macrosetae distributed on median portion of apical half. Subgenital plate, in lateral view ( Fig. 13 View Figure ), as long as pygofer; in ventral view ( Fig. 14 View Figure ), ligulate, 3.1 times longer than wide; apex subacute; ventral surface with one median macroseta. Connective ( Fig. 15 View Figure ) somewhat U-shaped, stem absent; total length about one-seventh of style length; dorsal surface with two parallel longitudinal keels. Style ( Figs 15, 16 View Figure ) with outer lobe developed and rounded; in lateral view ( Fig. 16 View Figure ), blade strongly expanded medially and slightly curved dorsally; ventral margin serrated, except base and apex; apex digitiform and strongly sclerotized. Aedeagus ( Figs 17, 18 View Figure ) with preatrium very short; dorsal apodeme developed and expanded laterally; atrium elongated and bearing pair of narrow, elongated, fragile processes, directed posterodorsally; shaft tubular and directed dorsally; with two pairs of elongate lateral processes, directed ventrally, apical pair slightly more robust than preapical pair.

Female unknown.

Etymology. The name of the new species alludes to the mottled aspect of the forewings ( Figs 11 View Figure , 44, 45 View Figure ).

Material examined. Male holotype: “ Brasil, Roraima, Caracarai\ Serra da Mocidade,\ 600m., 1°36’N \ 61°54’W, bandeja amarela\ + septo, 15–26.i.2016;\ F.F.Xavier F°; R. Boldrini\ & P. Barroso”; “DNA voucher\ Entomologia DZRJ \ ENTAbout ENT 3816” ( INPAAbout INPA).

Remarks. Polana (Declivella) maculosa  sp. nov. is similar to P. (D.) danesa  in appearance and color ( Figs 46, 47 View Figure ). However, P. danesa  differs in having the forewing with a lower density of maculae per cell, the style with a thinner blade that is strongly bent dorsally, and the aedeagus with stem expanded apically and bearing three pairs of processes.
