ABSTRACT
Three new species of the Asian genus Taeniodera Burmeister are described and illustrated: T. celebensis (North Sulawesi), T. inermis (Sabah) and T. bandahara (North Sumatra).
INTRODUCTION
T h e following descriptions of three new cetoniine beetles have resulted f r o m a partial revision of the material of this group kept i n the L e i d e n m u s e u m . T h e three new species belong to the genus Taeniodera Burmeister. T h e majority of its species are flower-frequenting inhabitants of O r i e n t a l rainforest regions. T h e first new species described below constitutes the second record of the genus for Sulawesi. T h e second novelty, from B o r n e o , may have been overlooked by other workers, because it nearly perfectly duplicates a k n o w n species. T h e third novelty was collected d u r i n g m y 1972 expedition to M t B a n d a h a r a i n N o r t h S u m a t r a . Taeniodera has recently been treated by M i k š i ć(1976), who mentioned ca. 50 species. H i s keys are artificial, a n d p e n d i n g a phylogenetically oriented reclassification of the T a e n i o d e r i n i m y statements o n the affinities of the new species can only be provisional. DESCRIPTIONS
Taeniodera celebensis sp. nov. (figs. 17) H o l o t y p e (male). — A p p r o x i m a t e length 18, w i d t h 7.5, height 5 m m . D e r m black, partly velutinous, largely covered w i t h dense, symmetrically patterned ochreous to l i g h t b r o w n t o m e n t u m . Pilosity yellowish, very abundant, but i n conspicuous. H a b i t u s like other Taeniodera species.

Identification. — Taeniodera celebensis stands isolated w i t h i n the genus. It is i m mediately recognizable by the combination of a reflexed clypeal m a r g i n , steep elytral lateral declivities, the overall colour pattern, the long h i n d tibial setae, and the shape of the parameres. H i t h e r t o only one Taeniodera species has been recorded from Sulawesi, Τ. nigrithorax Mikšić, w h i c h has, inter a l i a , very dif ferent colours; the thorax a n d the p y g i d i u m of that species are entirely black.

SPECIES O F T A E N I O D E R A
Identification. — T h i s species is characterized, inter alia, by its lightcoloured, loosely marmorate dorsal tomentous pattern on an opaque black substrate; by the distinctly 3-dentate fore tibiae; by the distinct external p r o t r u sions on the middle and h i n d tibiae; by the slight mesometasternal protrusion; by the abdomen being distinctly visible from above; by its parameres; and by its size. I n these characters T. bandahara differs from the superficially similar T. cervina (Wallace). T h e colour pattern is somewhat similar to T. inermis (described above) and T. marmorata (Wallace), but these species are very different i n other characters, i n c l u d i n g the parameral shape. M a t e r i a l examined. — H o l o t y p e male from N o r t h S u m a t r a : M t B a n d a h a r a : B i v o u a c T h r e e , 3°45 ' N-97°45 ' E , ca. 1810 m , 25.vii.1972, J . K r i k k e n , no. 25, in undisturbed montane multistratal evergreen forest.
