Diagnosis. Helicopsyche( F.) dinoprata sp. nov.is unlike any other species in the subgenus Feropsychein having broad, elongate inferior appendages pointed apically, each with its basomesal lobe short, forming a small protuberance with a single spine-like seta at its apex. Helicopsyche( F.) piroa Ross 1944, H.( F.) vergelana Ross 1956, and H.( F.) tapadas Denning 1966also have elongate inferior appendages, however they are obtuse apically, and the basomesal lobes are well-developed. Furthermore, the setation of tergum X is also distinctive for the new species.
Description. Adult. Similar to H. ( F.) bendego sp. nov.except as follows: Each foreleg anterior apical tibial spur about 2xlonger than posterior spur. Male forewing length: 4.4–4.9 mm(n = 10; holotypemale = 4.8 mm). Abdominal sternum VI ventral process moderately long, shorter than segment VI, tubular along its length, oriented posteroventrad, nearly straight in lateral view, with microtrichiae along length, apex rounded, with lamellae apicoventrally ( Figs. 3F, 3G). Male genitalia. Segment IX short ventrally; in lateral view with anteromesal margin well-developed, anterodorsal margin elongated, slightly sinuous, and anteroventral margin concave; lateral apodeme well-developed, located midlaterally on segment ( Fig. 3A); in dorsal view saddle-like, with anterior margin strongly concave ( Fig. 3B); in ventral view with anterior margin straight, anterolateral lobes projecting anterad, posterior margin convex, with mesal portion slightly projected ( Fig. 3C). Segment X, in lateral view, elongate, with dorsal and ventral margins subparallel, ventral margin abruptly tapering near apex, apex rounded ( Fig. 3A); in dorsal view not surpassing apices of inferior appendages, mesodorsal borders inverted Y-shaped, bearing 2 medially linear rows of 7–8 stout setae along length and a cluster of 6-8 stout setae apically, apex rounded, with slightly mesal notch ( Fig. 3B). Superior appendages originate dorsolaterally, setose, rounded in lateral view, nearly club-like in dorsal view ( Figs. 3A, 3B). Basal plate of inferior appendages finger-like in lateral view, not surpassing anteroventral margin of segment IX ( Fig. 3A), large and rounded at base in ventral view ( Fig. 3C); primary branches of inferior appendages each broad, strongly elongate, covered by long, stout setae; in lateral view narrow at base, strongly widening towards midlength, and then tapering apically, apex acute, dorsal margin strongly undulated ( Fig. 3A); in dorsal and ventral views curved mesad, tapering apically, with apex subacute, turned mesad ( Fig. 3B, 3C); basomesal lobe of each inferior appendage short, not visible in lateral view; in ventral view, slightly protruding from primary branch, bearing single spine-like seta ( Fig. 3C). Phallus tubular, strongly down-curved along its length; phallobase narrow, elongate, with apicoventral margin elongate, sclerotized, rounded apically; endotheca membranous lobe partially covering endophallus; phallotremal sclerite small, C-shaped ( Figs. 3D, 3E).

Distribution. Brazil( Rio de Janeiro).
Etymology. This species is named for Maxakalissaurus topai Kellner et al. 2006, an aeolosaurid dinosaur affectionally known as “Dinoprata”. Maxakalissaurus topaiis the biggest dinosaur described in Brazil, measuring about 13 meters and nine tons, and lived about 80 million years ago.
