Etymology. The name refers to the similarity in colouration pattern to M. marginicollis ; suffix -oides (grec.): similar as.
Description
Total length. 3.70–5.10 mm (mean 4.38 mm; n = 6).
Head. Very finely punctuated, blackish and shiny, as labrum and mandible. Antenna long and slender, extending to the middle of the elytra, blackish, only three basal antennomeres yellowish ( Figs 52b View Fig , 53A View Fig ). Third antennomere longer than second; ratio length of second to third antennomere 0.67–0.75 (mean 0.69); ratio length of third to fourth antennomere 0.38–0.43 (mean 0.41; Fig. 53B View Fig ).
Thorax. Pronotum very finely punctuated, broad, en- tirely yellowish. Pronotal width 1.20–1.55 mm (mean 1.37 mm), ratio length to width 0.58–0.63 (mean 0.60). Scutellum, meso- and metathorax black. Elytron yellowish with completely black margins ( Fig. 52b View Fig ), or only most parts of the suture, base, and part of margins beyond humerus black ( Fig. 53A View Fig ). Elytral length 2.90–3.95 mm (mean 3.48 mm), maximal width of both elytra together 2.00– 2.70 mm (mean 2.38 mm), ratio of maximal width of both elytra together to length of elytron 0.68–0.70 (mean 0.69). Legs entirely yellowish.
Abdomen. Yellowish, darker in the middle of abdomen.
Male genitalia. Median lobe long and strongly narrowed in the apical quarter ( Fig. 53C View Fig ), tectum short, broad at base. Median spiculae fine short bristles, later- al spiculae flattened, v-shaped, ventral spiculae weakly sclerotised as group of small spines ( Figs 53 View Fig Ca, Cb).
Female genitalia. Spermatheca with small spherical nodulus, long and curved median part and cornu ( Fig. 53D View Fig ). Dorsal pair of bursa sclerites with strong spines, ventral part more elongated, with serrate margins ( Fig. 53E View Fig ).
Diagnosis. Colouration pattern very similar to M. marginicollis , but M. marginicolloides sp. nov. is on average larger (total length 3.70–5.10 mm; M. marginicollis 3.25–4.00 mm), and elytra are a bit slenderer (ratio of maximal width of both elytra together to length of elytron 0.68–0.70; M. marginicollis 0.71–0.74). Other characters to differentiate these species are the yellow-brownish head and vertex with short central black stripe in M. marginicollis , while head in M. marginicolloides sp. nov. is completely black. The genitalic characters are very different and allow a clear differentiation of both species in any doubtful cases ( Figs 34C, D View Fig , 53C–E View Fig ).
Distribution. Known from Peninsular Malaysia and
Borneo ( Sarawak, Kalimantan, Brunei) ( Fig. 54 View Fig ).
