Type material. Holotype, male: BRAZIL, Bahia, [Elísio Medrado], Serra da Jibóia, Sede GAMBA [Environmentalist Group of Bahia] [12° 51' S; 39 28' W], (ligth trap), 10.v.2017, Silva-Neto, Mendes & Moura cols. (MZFS), specimen dissected, mounted on micro-slide.
Etymology. The specific epithet, from Latin maculosus, spotted, refers to the marks on hypandrium.
Diagnosis. Head without cornicula; eyes separated by 2.0 facet diameters; scape without internal protuberance; interocular suture inverted V-shaped; hypandrium with microtrichia arranged in circular groups; aedeagus symmetrical, bifid, digitiform with a medial external lobe; two pairs of parameres, external pair fused medially forming a U-shaped plate; internal pair well sclerotized, lanceolate.
Description. Male holotype. Head without corniculum. Vertex dorsally expanded. Eyes separated by 2.0 facet diameters; eye bridge with four facet rows; interocular suture inverted V-shaped; frons with hair patch not divided at center, extending dorsally and reaching the interocular suture (Fig. 1A). Scape subspherical, approximately the same length as pedicel, without internal protuberances. Antenna incomplete; first three flagellomeres fusiform, each one with pair of filiform ascoids (Fig. 1B). Relative palpomere proportion: 1.0:1.1:1.2:2.0 (Fig. 1C). Wing (Fig. 1D). 2.5 times longer than wide; wing membrane brownish, with costal cell darker; lighter spots between veins R 5 /M 1 to CuA; Sc not reaching C; sc-r absent; radial fork distal to medial fork; R 4 ending at wing tip; CuA not reaching wing margin. Male terminalia: hypandrium plate-like, subtriangular with microtrichia arranged in circular groups (Figs. 1E, 1F); length of gonocoxite 0.3 times the length of gonostylus; gonostyli narrow, basally inflated, bare, except in the base with patch of alveoli; aedeagus symmetrical, bifid, distally digitiform; two pairs of parameres, external pair fused forming a U-shaped plate; internal pair ending at the same place of aedeagus, well sclerotized, lanciform, ending in pointed apex; ejaculatory apodeme dorsoventrally flattened (Fig. 1E); epandrium 2.5 times wider than long, with two foramina and two distal patches of alveoli (Fig. 1G); cercus digitiform, 1.2 the length of epandrium; left cercus with 12 tenacula (Fig. 1F) and right cercus with 11 tenacula; hypoproct and epiproct subtriangular with apical micropilosity (Fig. 1G).
Female: Unknown
Remarks. Males of five species of Lepidiella have a head without cornicula: the Brazilian species L. flabellata Bravo & Santos, 2011, L. maculata sp. nov., L. olgae Bravo & Araújo, 2013 and L. spinosa Bravo, 2005, and one Costa Rican species, L. hansoni (Quate, 1996). The males of these five species can be recognized using the male identification key proposed below.
