Indonemoura mengla, Li & Yang & Li, 2025

Indonemoura mengla sp. nov.

( Fig. 1 View FIGURE 1 )

Adult habitus ( Fig. 1a View FIGURE 1 ). General color brown to dark brown. Head dark brown, antennae uniformly black, palpi lighter; compound eyes brown. Femora generally yellow but distally dark brown; tibiae slightly darker, tarsi brown; wings brown with dark veins.

Male ( Figs. 1b–g View FIGURE 1 ). Forewing length 6.7 mm, hindwing length 5.6 mm (n=2). Tergum IX ( Figs. 1b–c View FIGURE 1 ) lightly sclerotized except more darkly medially, lacking spines or long hairs along posterior margin. Sternum IX basally with claviform vesicle, apical half slightly enlarged ( Figs. 1d–e View FIGURE 1 ); hypoproct subrectangular at basal half, slightly incised medially, distal half gradually tapering and tubular ( Figs. 1f–g View FIGURE 1 ). Tergum X mostly sclerotized, with anteromedial portion membranous posterior to a triangular anterior sclerite ( Fig. 1c View FIGURE 1 ). Cercus slightly sclerotized, nearly cylindrical, length ca. 2.5x width. Epiproct ( Figs. 1b–c View FIGURE 1 ) long and recurved, lateral sides nearly parallel-sided for most length, with a weak lateroapical extension and an mesoapical interruption of sclerotization. Dorsal sclerite with narrow, lateral sclerites delimiting a large, membranous dorsal area ( Figs. 1b–e View FIGURE 1 ); ventral sclerite strongly sclerotized, basal half nearly parallel-sided and widened toward apex in lateral aspect, subapically forming a small, rounded ventral ridge ( Figs. 1d–e View FIGURE 1 ). Paraproct with three lobes; inner lobe long and narrowly triangular with apex projecting near the base of epiproct ( Figs. 1f–g View FIGURE 1 ); median lobe basally fused with inner lobe but apical half forming a sclerotized isolated prong similar to inner lobe in shape and size; outer lobe darkly sclerotized, generally adjacent to median lobe; its apical prong curved dorsally and inward, distally obtuse and much longer than inner and median lobes ( Figs. 1d–g View FIGURE 1 ).

Female. Unknown.

Type material. Holotype: male ( CAU), China: Yunnan Province, Xishuangbanna, Mengla County, Yaoqu , Nangua River , 795 m, 21.7246°N, 101.5453°E, 2011.V.1, light trap, leg. Yan Li. GoogleMaps Paratype: 1 male ( HIST), same data as holotype GoogleMaps .

Etymology. The name refers to Mengla County where the types were collected.

Distribution. Presently known only from the type locality, Mengla County of southern Yunnan Province.

Remarks. There are no species occurring in China that is morphologically similar to I. mengla sp. nov., except I. curvispina Li, Wu & Yang, 2017 , in sharing a similar femoral pattern, but their terminal characters differs dramatically (see their figs. 1–5, 11). Indonemora mengla sp. nov. is most similar to I. malickyi Sivec & Stark, 2010 , a species described from Thailand in sharing a similar lateral aspect of epiproct. However, the new species can be easily separated from I. malickyi by the median lobe of the paraproct being shorter than outer lobe and bearing a triangular apex. For I. malickyi , the median paraproct lobe is much longer than the outer lobe and slightly bifurcate (fig. 41 in Sivec & Stark 2010).
