Mouthparts well developed, maxillary palpus
and labial palpus
covered with light brown scales.
The Drosophila maxillary palpus
is a highly derived sensory appendage.
Colour: Head orange, except for black palpus
and swollen part of frontal vitta; notum and upper pleuron brick-red; foreleg black, except tarsus; tarsomeres 1-3 white, distal tarsomeres dark; mid femur black with orange apex, mid femur orange at base and apex; abdomen black, except for extreme base and white fasciae across pleuron on segments 2 and 3 (Fig.

in prolateral view (A, G), left palpus
in ventral view (B, H), left palpus
in retrolateral view (C, I), habitus dorsal (D, J), habitus ventral (E, K) and habitus lateral (F, L).
Mouthparts: labellum triangular in frontal view, with microsetae; palpus
Labrum long-attenuate with two pairs of ventral setae; labella hemispherical, each with some lateral setae and two pairs of short setae; palpus
with four segments: 1st segment shortest, globose as long as wide, 2nd-4th segments cylindrical, 2nd segment widest, 1.5 as long as wide; 3rd segment 3 times as long as wide, 4th segment longest, 3.5 times as long as wide, all with widely scattered setae and scales.
The members of the tribe Bulaeini were also differentiated from the other tribes of the subfamily Coccinellinae by having clypeus with broad anterolateral emerginations; gena never extending on to eye; mandible large with bifid apex; maxillary palpus
with terminal segment with dosrsal margin strongly produced anteriorly weakly securiform; pronotum convex anteriorly never excavated anterolaterally.
with slight apical dilation, no more than twice the palpal base width (Fig.
