Diagnosis. This species has two distinct structures by which it differs from the other species of the genus, the lateral sutures of segment IX and the very sclerotized inferior appendage having a basomesal lobe ( Fig. 9D ). Two species have lateral divisions of the pleura of the segment IX similar to those of Marilia puri sp. nov.: M. mathisi Bueno-Soria & Rojas Ascencio 2004 and M. manicorei Camargos, Pes & Hamada 2020 . However, segment X of M. mathisi is longer than the pre-anal appendage, wider in lateral view and with a subapicoventral projection, and its inferior appendage has a poorly pronounced basomesal region. The basomesal region of the inferior appendage of M. manicorei also forms a projection as in Marilia puri sp. nov., but segment X is completely different: in M. manicorei segment X is longer than the preanal appendage and with a deep notch forming arrow-like apical lobes, while in Marili a puri sp. nov. segment X is slightly shorter than the preanal appendage and its apex has a very shallow notch and roundish apex ( Fig. 9C ).

Description. Adult male. Forewing 7.2 mm (holotype). Body and forewings dark brown in alcohol ( Fig. 8A ). Head: Eyes large, touching each other at vertex for most of their length ( Fig. 8B ). Antenna long, about two times length of body, with narrow annuli; scapes wide, brown. Maxillary palp well developed, 5-articulated, heavily covered with setae. Labial palp 3-articulated, covered with setae. Vertexal mediantennal wart single, compact, small, round; vertexal lateroantennal wart compact, small, oblong; occiptal warts elongate, narrow, posterior warts elongate, narrow. Thorax: Pronotum narrowly transverse, with transversely elongate setal wart. Mesonotum wide, with small diffuse setal wart and posterior depression area; mesoscutellum almost circular, with anterior margin slightly acute, without setal warts ( Fig. 8B ). Tibial spur formula 2-4-4. Forewing forks I, II and V present; hind wing forks I and II present. ( Fig. 9A ). Abdomen: Preterminalic segments I–VIII simple, without differentiated structures.

Male genitalia ( Figs 9B–9F ): Segment IX, in lateral view ( Fig. 9B ), with anterior margin substraight and posterior margin slightly projected at mid-height; mid-lateral sutures separating each side of segment IX into 7 parts ( Fig. 9B ): ventral part narrow, 4 lateral parts (dorsoposterior part small, round; mesoposterior small, subtriangular; ventroposterior large, subtriangular; anterior part narrow and tall), and 2 dorsal parts (anterior part large, posterior part small); in dorsal view ( Fig. 9C ), anterior part wide, trapezoidal, delimitated from posterior part by curved suture, posterior part narrow, posterior margin slightly protruding, round; in ventral view ( Fig. 9D ), sutures separating segment IX into 4 parts (anterior part transverse across segment IX width; posterior parts with middle part pentagonal and lateral parts elliptical). Preanal appendage, in lateral view ( Fig. 9B ), slightly longer than segment X, slender, with apex blunt; in dorsal view ( Fig. 9C ), claviform with base narrower than apex, setose. Segment X, in lateral view ( Fig. 9B ), with apex truncate; in dorsal view ( Fig. 9C ), subquadrate, wider at base, narrower at middle, slightly enlarged subapically, apex with shallow mesal notch. Inferior appendage bi-articulated: in lateral view ( Fig. 9B ), coxopodite cylindrical with base wider than apex; in ventral view ( Fig. 9D ), with basomesal lobe; harpago short with small conical spines apically ( Figs 9B, 9D ). Phallus, in lateral view ( Fig. 9E ), tubular slightly curved near base, straight in ventral view ( Fig. 9F ); endotheca membranous; phallotremal sclerite hook-shaped in lateral view ( Fig. 9E ).

Etymology. The specific epithet “puri” is the name of the indigenous people who lived along the states of Southeastern Region of Brazil, throughout the Paraiba do Sul basin. In Espírito Santo State, they were distributed in the central and southern regions of the state. The name is used here as a noun in apposition with unvarying gender.

Distribution. Brazil (Espírito Santo).
