Abstract: Notodoma fungorum Lewis, 1884 (Figure 1) (Korean name: Ju-hwang-gin-da-ri-pung-deng-i-boot-i) Notodoma fungorum Lewis, 1884: 136. Notodoma formosanum Bickhardt, 1912: 126. Notodoma orientale Lewis, 1903: 425. Notodoma saturum Lewis, 1902: 267. Redescription. Body (Figs. 1A–D) 2.7–4.8 mm long and 2.3–4.3 mm wide; globose, strongly convex; mostly reddish brown with yellow maculae on elytral base; surface strongly glossy. Head (Fig. 1E) covered with irregular-sized punctures, fairly larger at posterior part, average distance between punctures about two times greater than its diameter, rather sparser and finer marginally; frontal stria well-impressed, parallel-sided, broadly interrupted anteriorly; epistome almost hexagonal, straight at apex; labrum arcuate. Pronotum wide, convex, almost inverted pentagonal, weakly bi-emarginate at anterior margin, protruded medio-posterad at base; marginal pronotal stria complete; surface evenly covered with fine punctures, average distance between punctures about two times greater than its diameter, rather larger and coarser laterally; with broad and weak depression behind anterior angle along lateral margin. Scutellum small, triangular. Elytra (Fig. 1I) convex; surface wholly and evenly covered with microscopic punctures, finer and sparser than those of pronotum; epipleural marginal stria complete and crenulate; elytral marginal stria complete and crenulate, with an additional crenulated stria with row of punctures at middle just above elytral marginal stria; outer subhumeral stria present from basal one-third, extending along apical margin of elytron and united with the end of sutural stria; dorsal striae 1, 2, 4 complete; dorsal stria 3 present rudimentary, weakly impressed on basal one-third, mostly obsolete; dorsal stria 5 absent; sutural stria complete, basal end almost united with the basal end of stria 4, narrowly interrupted, apical end united with apical end of outer subhumeral stria. Propygidium broad, strongly convex; surface evenly punctate, gradually larger and sparser posterad. Pygidium (Fig. 1F) covered with slightly finer and sparser punctures than propygidium, gradually finer and denser posterad. Prosternum (Fig. 1G) wide, broadly rounded at anterior margin; marginal stria complete; surface mostly covered with regular-sized punctures; prosternal keel broad, with a pair of distinct and parallel striae on each side, deeply emarginated at apex. Mesoventrite (Fig. 1H) distinctly bisinuate at anterior margin; surface sparsely covered with fine punctures; mesoventral marginal stria complete, crenulate; secondary marginal stria shortly present between mesoventral marginal stria and antero-lateral angles of mesoventrite, broadly interrupted at middle; meso-metaventral suture complete, distinctly crenulate. Metaventrite (Fig. 1H) broad, trapezoidal; surface covered with irregular-sized punctures, fairly larger laterally; intercoxal disc of metaventrite with a pair of oblique striae, extending from each anterior angle of metacoxae, converging at basal three-fifths of median longitudinal suture; lateral disc covered with large and coarse punctures, gradually larger outwardly. Abdomen composed with five visible ventrites; intercoxal disc of abdominal ventrite 1 punctate as metaventrite, larger and sparser laterally, with a pair of complete and crenulate striae on each side; ventrites 2–5 barely visible, each apical margin closely overlapped. Legs slender; protibia (Fig. 1J) with 11 small denticles on outer margin, with a deep and straight tarsal groove. Male genitalia shown as Figures 1K–P; ratio in length of paramere to basal piece of aedeagus about 0.4. Female genitalia shown as Figures 1Q–S. Material examined.

Lloyd on dying tree (SNU); 2 females, Republic of Korea,. Jamgok-ri, Geunnam-myeon, Cheorwon-gun, Gangwon-province, 01–18.VI.2024, Seung et al. leg., collected by FIT (SNU). Distribution. China, Japan, Korea (Peninsula, Jeju Is.), Myanmar, Taiwan, Vietnam. Remarks. This species has wide distributional range through East and Southeast Asia. Most of them were observed on fungi, such as Laetiporus sulphureus (Bull.) Murrill., Trametes versicolor (L.) Lloyd, and white thick fungal mycelium, where other dipteran and coleopteran species present. They usually occurred between late May to early July in Korea.
