Description. Heteroglymma echinatum Heller , lectotype, male. ( Fig. 24a View FIGURE 24 ). Length. Pronotum plus elytron 5.00 mm. Integument black, largely covered with appressed, greyish-white scales partly abraded. Head with transverse angulate furrow separating rostral base, leading ventrad in front of eye; vertex with radial furrows laterally distinct. Eyes conically protruding. Rostrum 1.14 X longer than wide, sides subparallel; apical declivity with sunk-in scales, with sparse erect setae; dorsum simple. Pronotum 1.14 X longer than wide; with coarse punctures, with greyish-white scales partly abraded; with interspersed suberect claviform scales. Elytra 1.23 X as long as wide; densely covered with greyish-white scales; intervals with interspersed erect light brown scales, longer than interval´s width; interval 6 with small tubercle adorned with few erect dark brown scales. Genitalia. Penis ( Fig. 24b View FIGURE 24 ) with sides of body subparallel to rounded apex. Apodeme 2.00 X as long as body of penis. Transfer apparatus curved. Intraspecific variation. Length. Pronotum plus elytron 4.50–5.80 mm. Female ( Fig. 24d View FIGURE 24 ) with elytra more roundish. Female terminalia. Fig. 24e View FIGURE 24 .

Notes. The species names N. echinatus (Heller) and N. bipusulosus (Heller) can be considered synonyms with greatest confidence. The type localities, Swela and Sapit, are located in the same area of East Lombok; in fact, the type specimens may come from the same patch of forest as their cox1 sequences differ in only one single position.
