On Brazilian Austrotinodes Schmid, 1955 (Insecta, Trichoptera, Ecnomidae): new species, new distributional records and an updated checklist Leandro Lourenço Dumas Wagner Rafael M. de Souza European Journal of Taxonomy 2017 2017-03-13 297 1 40 Leandro Lourenço Dumas & Wagner Rafael M. de Souza, 2017 Leandro Lourenço Dumas & Wagner Rafael M. de Souza 2017 [582,908,1516,1543] Insecta Ecnomidae Austrotinodes Animalia Trichoptera 7 8 Arthropoda species berthalutzae sp. nov.   Figs 3, 14    Diagnosis The new species resembles  A. adamsae Flint, 1996and  A. contubernalis Flint & Denning, 1989in having an elongate lateral process of the phallus with a single spine on the dorsal branch and two on the ventral branch, the first median and the second apical. The phallic guide, in lateral view, is also similar in all three species, but shorter in  A. contubernalis.The intermediate appendages can easily distinguish this species from  A. adamsaeand  A. contubernalis, both of which have four spines on the appendage, whereas  A. berthalutzae sp. nov.bears only three. Additionally, in  A. berthalutzae sp. nov.all spines are apically positioned, while in  A. adamsaeand  A. contubernalisone stout spine is positioned at apical third and midlength, respectively. The new species is also similar to  A. amazonensisin the shape of segment IX and in having a straight phallic guide; additionally, the inferior appendages of both these species are short and subrectangular in lateral view. However, in  A. amazonensisthe posterior margin of inferior appendages possesses a wide V-shaped incision in ventral view, whereas in  A. berthalutzae sp. nov.the mesal emargination is shallow.    Etymology The specific name is a tribute to Bertha Maria Júlia Lutz, Adolfo Lutz’s daughter, who was born in São Pauloin São Paulostate in 1894 and died in 1976. She became the second Brazilian woman to join the public services in Brazil, serving for four decades as a teacher and a researcher at the Museu Nacional. Bertha Lutz was internationally recognized for her valuable contribution to zoological research, specifically on Brazilian amphibians. Furthermore, she became a tireless defender of women’s rights in Brazil, making an important contribution to the fight for women’s suffrage in the 1930s.    Material examined     Holotype  BRAZIL: ♂, Mato Grosso do Sul,  Bonito, Hotel Cabana, Rio Formosinho, 21º10′16″ S, 56º26′47″ W,  277 m,  8–13 Sep. 2013, A.P.M. Santosand D.M. Takiyaleg. ( DZRJ).     Paratypes  BRAZIL: 3 ♂♂, same data as holotype( DZRJ).    Description ADULT. Length of forewing 3.04–3.26 mm(n = 4). In alcohol, general color brown, with golden brown sclerites; antennae stramineous, dorsum of head golden brown, with pale yellow and dark brown setae; thorax golden brown dorsally, light yellow ventrally; legs yellow, legs segments with brown setae; wings pale brown, forewing with fine pale brown setae dorsally. WINGS. Forewing with R1 forked apically, forks II–V present; hind wing with forks II, III and V, discoidal cell absent. MALE GENITALIA. Segment IX deeply divided, sternum elongate; in lateral view enlarged subapically, ventral margin slightly convex; in ventral view, about 2 times as long as wide, narrow at base, enlarging apically, apical margin slightly convex. Phallic guide darkly sclerotized, elevated over inferior appendages; in lateral view, almost straight, forked at the slightly broad base, apex subacute, reaching apex of inferior appendage. Inferior appendages fused mesally, attached apicomesally on sternum IX; in lateral view short, subrectangular; in ventral view less wide than sternum IX, posterior margin slightly convex and crenulated, with shallow mesal emargination, without lateral lobes. Tergum X divided into pair of semimembranous subtriangular lobes, bearing slender dorsal setae along inner margin and a long seta at apex; in lateral view, subrectangular. Preanal appendages long, surface setose, margin crenulated, parallel-sided, apex rounded. Intermediate appendages almost ⅔ length of preanal appendage; in lateral view, enlarging apically, slightly curved dorsomesally, apex enlarged, asymmetric; left appendage with bilobed apex, bearing three spine-like setae directed posterad, one in dorsal lobe and two in ventral lobe; right appendage with irregular distal margin, with three spine-like setae (asymmetry also occurs in paratypes). Phallus with sclerotized phallobase and membranous apicodorsal region; lateral process elongate, bifid; dorsal branch short, directed posterodorsoapically, with an elongate apical spine; ventral branch long, wide, rounded apically, with three spines, one near base, one positioned almost at median region, and one at apex; basomesal process elongate, narrow, darkly sclerotized, with pointed apex.    Distribution Brazil (MS). 1638541549 2013-09-08 2013-09-13 2013-09-08 DZRJ A.
