Brasineura hpba Reategui, Pereira, Rafael & Silva-Neto 2026, sp. nov.

Brasineura hpba Reategui, Pereira, Rafael & Silva-Neto sp. nov. urn:lsid:zoobank.org:act: 91149DE4-9BB4-4E72-8FD2-E7C7B09B4DEC Figs 1–2, 7 Diagnosis This species is similar to B. spinosa and B. renaissance Reategui, Pereira, Rafael & Silva-Neto sp. nov. in the general structure of the phallobase. It is close to B. renaissance in the external parameres that are not forked distally but differs from it at the phallobase which bears numerous small spines, which are heavily sclerotized and arranged in a concave band embedded within a membranous matrix. Three pairs of endophallic sclerites are present: antero-lateral pair long and slender; antero-mesal pair is M-shaped, with stout anterior arms that contact medially, forming inwardly curved projections, and a posterior portion that is sinuous and gently inward curved; posterior pair stout, distally curved outwards, blunt ended, close to the external parameres. Etymology The specific epithet is treated as a noun in apposition and refers to an invariable letter combination corresponding to the acronym of the Hospital Português da Bahia (HPBA), an emblematic healthcare institution in the state of Bahia, Brazil. The name honors the essential medical care provided to AMSN and his family members.

Description Male COLORATION. Body pale yellow with brown and pale brown areas as indicated below. Compound eyes black, ocelli hyaline, with ochre centripetal crescents (Fig. 1A–B); head pattern (Fig. 1B). Legs with coxae, trochanters and femora creamy white, tibiae and tarsomeres pale yellow. Fore-hindwings hyaline (Fig. 1C–F). MORPHOLOGY. Compound eyes without interommatidial setae (Fig. 1B). Outer cusp of lacinial tip broad, with six denticles and markedly sclerotized (Fig. 1G); labial palps almost triangular (Fig. 1H); mandibles asymmetrical, elongate and with outer margin angled (Fig. 1J–K). Forewing pterostigma elongate, constricted proximally, widest in middle. Areola postica tall, broadly triangular, with apex rounded. Rs almost straight, R 2+3 and R 4+5 slightly sinuous. M stem slightly concave proximally, then almost straight. Right forewing M of five branches, with M5 three branched, resulting in M 5a1, M 5a2 and M 5b (Fig. 1E). Left forewing M of six branches (Figs 1F, 2A–E; see also variation of paratype below). Right hindwing Rs-M joined, M of two branches (Fig. 1C). Left hindwing M of three branches (Fig. 1D). Paraprocts (Fig. 1M) stout, broad, elongate, distally curved outward, sensory fields with 33 thichobothria on basal rosettes, setae as illustrated (Fig. 1M). Epiproct (Fig. 1M) anteriorly convex, sides converging to round posterior border. Hypandrium with posterior projection with slightly accentuated apex, straight median anterior region, gently dark spot in center of structure (Fig. 1I). Phallosome (Fig. 1L) with side struts proximally fused, external parameres distally not forked, with sharp, heavily sclerotized projection on inner side. Phallobase with numerous small spines heavily sclerotized forming concave band in membranous matrix; three pairs of endophallic sclerites are present: antero-lateral long pair slender; antero-mesal pair M-shaped, with stout anterior arms that contact medially, forming inwardly curved projections, and posterior portion sinuous and gently inward curved; posterior pair stout, distally curved outwards, blunt ended, close to external parameres.

Variations in the forewing veins The following text describes the five distinct variations of forewing veins identified in male specimens of B. hpba Reategui, Pereira, Rafael & Silva-Neto sp. nov. Type 1. Forewing M with five branches, M 5 branched resulting in M 5a and M 5b (Fig. 2A). Type 2. Forewing M with six primary branches and without secondary branches (Fig. 2B) Type 3. Forewing M with six branches, M 6 branched resulting in M 6a and M 6b (Fig. 2C). Type 4. Forewing M with five branches, M 4 and M 5 branched resulting in M 4a and M 4b, and M 5a and M 5b, respectively (Fig. 2D). Type 5. Forewing M with seven primary branches and without secondary branches (Fig. 2E).
