New species of Helicopsyche von Siebold 1856 (Trichoptera: Helicopsychidae) from Brazil, including the redescription of Helicopsyche (Feropsyche) planorboides Machado 1957 Dumas, Leandro Lourenço Nessimian, Jorge Luiz Zootaxa 2019 2019-06-19 4619 2 231 250 Dumas & Nessimian, 2019 Dumas & Nessimian 2019 [151,604,1906,1933] Insecta Helicopsychidae Helicopsyche Animalia Trichoptera 5 236 Arthropoda species dinoprata sp. nov. Feropsyche  ( Figures 3A–3G)  urn:lsid:zoobank.org:act: 78355E46-538E-44A3-92B7-DB36015CE5F4   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).     Holotypemale:  BRAZIL: Rio de Janeiro: Santa Maria Madalena, Parque Estadual do Desengano, Morumbeca dos Marreiros, afluente do Ribeirão Macapá, 21°52’39.0” S, 41°54’55.3” W,  21.x.2016, 1110 m, LL Dumas, JL Nessimian& JF Barbosaleg.

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. It was found in the city of Prata, Minas Gerais, Brazil, in 1998. A reconstructed  Maxakalisaurus topaiskeleton was on display at the Museu Nacional, being one of the main attractions of the public exhibition. 2268317461 2016-10-21 DZRJ Morumbeca dos Marreiros & LL Dumas & JL Nessimian & JF Barbosa Brazil Santa Maria Madalena -21.8775 Ribeirao Macapa 1 -41.915363 Parque Estadual do Desengano 6 237 1 Rio de Janeiro holotype 2268317482 [199,1214,1302,1330] 2016-10-21 DZRJ Morumbeca dos Marreiros & LL Dumas & JL Nessimian & JF Barbosa Brazil Santa Maria Madalena -21.8775 Ribeirao Macapa 1 -41.915363 Parque Estadual do Desengano 6 237 3 2 1 Rio de Janeiro paratype 2268317447 2016-10-21 MZSP Morumbeca dos Marreiros & LL Dumas & JL Nessimian & JF Barbosa Brazil Santa Maria Madalena -21.8775 Ribeirao Macapa 1 -41.915363 Parque Estadual do Desengano 6 237 2 1 1 Rio de Janeiro paratype 2268317463 2016-10-22 DZRJ LL Dumas, JL & Nessimian & JF Barbosa Brazil Santa Maria Madalena Morumbeca -41.91528 Parque Estadual do Desengano 6 237 5 3 2 Rio de Janeiro paratype 2268317458 2016-10-21 DZRJ LL Dumas, JL & Nessimian & JF Barbosa Brazil Sao Fidelis -21.875305 Morumbeca 1 -41.915028 Parque Estadual do Desengano 6 237 7 2 5 Rio de Janeiro paratype 2268317457 DZRJ JR Mermudes Brazil Itatiaia 2012822 -22.455278 Trilha 1 -44.61222 Parque Nacional do Itatiaia 6 237 4 2 2 Rio de Janeiro paratype 2268317450 2012-01-26 DZRJ Sampaio & Oliveira Brazil Itatiaia -22.330473 Rio Preto 1 -44.615414 Maromba 6 237 1 1 Rio de Janeiro paratype 2268317453 LS, DZRJ Barbosa Brazil Mangaratiba 2016400 -22.89939 Sahy 1 -43.98761 Parque Estadual do Cunhambebe 6 237 16 7 9 Rio de Janeiro paratype 2268317455 2012-08-18 PM, DZRJ Souto Brazil Paraty -23.041777 Rio Taquari 1 -44.69589 Sertao do Taquari 6 237 2 1 1 Rio de Janeiro paratype 2268317480 2018-08-23 DZRJ LL Dumas & JL Nessimian Brazil Cachoeiras de Macacu -22.42086 Reserva Ecologica de Guapiacu 1 -42.738945 Guapiacu 6 237 2 2 Rio de Janeiro paratype
