Paramaka lucimarae Salles & Domínguez sp. nov.

( Figures 4A–F )

Paramaka sp. Marulanda-Lopez et al., 2020: 8.

Diagnosis. Male imago: 1) abdominal color pattern uniformly tinged with orangish-brown; 2) posteromedial projection of styliger plate short and not curved; 3) telopenis base located at apical 2/3 of penis lobe; 4) telopenis well developed and sclerotized, crossing medially, apex slightly expanded.

Description of male imago (in alcohol). Lengths: body, 5.4–5.5 mm; fore wings: 6.1–6.4 mm; hind wings: 1.0 mm.

Head ( Figs. 4A–B ): orangish-brown, upper portions of eyes orange-brown, lower portions blackish. Eyes meeting on meson of head. Ocelli white surrounded with black. Antennae: scape brown, pedicel white and flagelum broken-off and lost.

Thorax ( Figs. 4A–B ): pronotum brown with lateral and submedial blackish line; mesonotum brown with lighter sutures, area between posteroscutellar protuberances and mesoscutellum washed with white. Metanotum brown. Pleurae yellowish washed with purplish-grey. Mesosternum yellowish-brown with carina darker. Membranous areas between pro- and mesosternum, and metasternum translucent brown. Wings: membrane of fore and hind wings hyaline, slightly tinged with brown at bases. Fore wing with longitudinal veins yellowish-brown, cross veins whitish. Fork of MA asymmetrical and fork of MP slightly asymmetrical (MP2 connected directly to MP1); crossvein above MA slanted; vein ICu 1 connected to CuA basally by a cross vein, vein ICu 2 basally free or attached at base to ICu 1 by crossvein. Legs: coxae and trochanters brown, femora, tibiae and tarsi yellowish-brown, claws lighter than tarsi.

Abdomen ( Figs. 4A, C ): terga brown, tergum I heavily washed with grey, terga VII–X heavily washed with orange; terga II–X with greyish medial stripe; sterna I–VI translucent brown, sterna VII–IX orangish-brown ( Figs 4A, C ). Genitalia ( Fig. 4D ): styliger plate yellowish-brown; penes white, telopenis brown; forceps white. Styliger plate with poorly developed triangular projection medially. Telopenis arising close to the apex of the penes lobe, relatively short; apex of penes lobe truncate. Caudal filaments broken-off and lost.

Description of female subimago (in alcohol). Lengths: body, 6.9 mm; fore wings: 7.3 mm; hind wings: 1.2 mm. Similar to male imago, except for: yellowish general coloration ( Fig. 4F ); area between ocelli washed with orange; area between compound eyes and pronotum washed with grey ( Fig. 4E ); anteronotal transverse impression, anterolateral scutal costa and posterior margin of scutellum tinged with brown.

Female imago and nymph: unknown.

Etymology. We are honored in naming this species after our friend and colleague Lucimar G. Dias, mayfly specialist and collector of the species. The specific epithet “lucimarae ” is in the genitive case, singular.

Distribution. COLOMBIA: Meta and Putumayo.

Comments. The male imago of Paramaka lucimarae sp. nov. can be readily distinguished from the other species of the genus, except for P. pearljam , by its overall orangish-brown uniform coloration. Both species, however, can be distinguished from each other based on the size of the posteromedial projection of the styliger plate, which is very short in the new species, whereas in P. pearljam it is long and ventrally curved at the apex. Concerning the overall morphology of the male genitalia, the new species is more similar to P. convexa and P. incognita . The main characteristic that distinguishes it in Paramaka lucimarae sp. nov. is the length of the distal part of the penis lobe, which is much shorter when compared to these two species.
