Type material. Holotype ♂ ( IEBR), Lam Dong Province, Lac Duong, Langbian Moutain , hand net, 2-3.vi.2002 ; Paratypes: 2 ♀♀ ( IEBR), the same data as for the holotype ; 1♀ ( NSMT), Mt. Lang Biang, nr. Da Lat , Lam Dong Pr. [ S-VI- ETNAM], 3.vi.2002, S. Nomura leg.
Description of the holotype (male). General: Body length 14.5 mm; width 6.3 mm, widest at humeral umbone, gradually narrowed backward. Body brown. Surface with fulvous, brown, light yellow and black setae, and yellow tomentous maculae. Head: Dorsal surface with dense, setiferous punctures; setae fulvous, long. Clypeus with weak brown metalic reflections; anterior margin slightly notched, and slightly raised; clypeolateral ridge not distinct; sides with yellow maculae ( Fig. 2e View FIGURE 2 ). Frons with a morderately raised longitudinal ridge. Maxillary palpus and labial palpus dark brown to light brown. Antenna brown, antennal club long, approximately 2.1 times length of antennomeres 2–7 combined; inner side of antennomere 8 with short, dense, fulvous satae. Ventral surface clad with long, yellowish setae ( Fig. 3a View FIGURE 3 ). Pronotum: Widest at base, basomedian area depressed. Lateral margin curved; posterior margin distinctly protruded. Surface clad with long, yellow, and black setae except for basolateral area; median area with a longitudinal yellow tomentous maculae ( Fig. 2g View FIGURE 2 ). Scutellum: Black, surface clad with long, white yellow setae; median area with a longitudinal yellow tomentous maculae gradually narrow at apex. Elytron: With posthumeral macula, lateral macula, small median macula, and distal macula ( Figs. 1a View FIGURE 1 , 2c View FIGURE 2 , 3c View FIGURE 3 ); median macula small and divided into two small parts ( Fig. 3c View FIGURE 3 ). Surface densely clad with setae; setae on maculae and disc long and light yellow; setae black behind humeral umbone and on lateral and distal declivity; setae dark brown on juxtascutellar area; setae fulvous along lateral margins; humeral umbone glabrous ( Fig. 1a View FIGURE 1 ). Mesepimeron: Dark brown, clad with yellowish setae, and yellow tomentous maculae. Metepisternum and metepimeron: dark brown, clad with yellowish setae. Sternum: Preprosternum dark brown, almost glabrous. Mesosternum black, clad with long, sparse, light yellow setae. Mesometasternal process short, glabrous, brown, apex rounded; mesometasternal suture depressed, almost without setae. Metasternum dark brown, with long, sparse, yellow setae; middle portion glabrous ( Fig. 3e View FIGURE 3 ). Pygidium: Brown; with a yellow macula. Sides clad moderate setae, dense, fulvous and dark brown; macula clad light yellow setae ( Fig. 2c View FIGURE 2 ). Abdomen: Without median groove; median portion almost glabrous, with only some short, yellow setae. Six abdominal sternites visible; sternites II–V clad with yellow setae; setae on sternite II long, dense; setae on sternites III–V short, sparse, but shorter on sides; sternite VII with sparse, long, fulvous setae on sides. Sternites II–VI with a distinct, yellow macula close to posterior margin on each side; surface densely clad with fulvous, dark brown, and yellow setae in dorsal and lateral portion ( Fig. 1b View FIGURE 1 ). Legs: Slender, simple. Metacoxa dark brown; almost glabrous. Femora and tibia reddish-brown; clad with long, light yellow setae. Protibia without tiny teeth ( Fig. 3f View FIGURE 3 ); spine near the middle of outer margin of mesotibia sharp, but absent in metatibia ( Fig. 3g View FIGURE 3 ); metatibia with a row of sparse, light yellow setae along inner margin; dorsal tooth of metatibia longer than basitarsus of metatarsus; outer tooth absent. Tarsi dark brown; basitarsus of metatarsus with a cluster of sparse, long setae. Genitalia: Parameres moderate broad and long; apex transverse. Interparameral split narow, gradually constricted to ¾ lenght of parameres; base with membrane, distinctly divided in medial ( Fig. 2a,b View FIGURE 2 ).
Female ( Figs 1c,d View FIGURE 1 ; 2d,f,h View FIGURE 2 ; 3b View FIGURE 3 ). Langer than the male; body length 15.3–16.0 mm; width 6.8–7.0 mm. Body color darker. Surface of head with more dense, setiferous punctures; with long, sparse fulvous and yellowish setae; midline of frons convex, glabrous. Pronotum with a longitudinal yellow tomentous maculae, but smaller and shorter than the male ( Fig. 2h View FIGURE 2 ). Clypeus, scutellum, mesepimeron, sternites II–VI, and pygidium without yellow tomentous maculae ( Fig. 2f,h View FIGURE 2 ). Posthumeral macula, lateral macula, and median macula on elytron smaller than male ( Fig 1c,d View FIGURE 1 ; 3d View FIGURE 3 ). Antennal club shorter than the male, nearly 1.5 times length of antennomeres 2–7 combined ( Fig. 3b View FIGURE 3 ).
Differential diagnosis. Male of Macronotops flavomedius new species is similar to M. vuilleti and M. dianensis , and their differences are summarized in the Table 1.
Etymology. The new species is named after its yellow macula on the middle of pronotum ( Fig. 2g View FIGURE 2 ).
Distribution. Vietnam (Lam Dong Province). Macronotops flavomedius new species is the southern-most species of the genus Macronotops .
