Differential diagnosis

Onitisphilemon is smaller in size than O. singhalensis and resembles the latter in the presence of a broad deep longitudinal groove on the metasternum anteriorly and the scarcely punctured pygidium. It differs from the latter in the clypeal sculptures and the absence of a tooth on the profemur of males. In O. singhalensis the basal pronotal foveae are rounded and closer than in O. philemon (compare Fig. 15D, F View Fig ) and the pronotum is with a smooth longitudinal median line which extends to the front margin, while the median line is absent in O. philemon (compare Fig. 14D, F View Fig ).

Remarks

In the original description of this species, collection data of the type material are not provided. The Historical Fabricius collections, earlier kept at ZMUC and recently transferred to ZMUK, has three specimens with a simple label ‘ Philemon ’ that matches the original description, which were designated as syntypes of Onitisphilemon. One of these specimens with code ZMUK Fabricius 003706 is now designated as lectotype and two other specimens’ ZMUK Fabricius 003707 and ZMUK Fabricius 003708, are designated as paralectotypes.

Description

MEASUREMENTS (in mm). TL=14–19, BW= 7.5–10.5.

Male

Green, coppery or bronzy black, moderately shining, oval; clypeus ( Fig. 9D View Fig ) parabolic with a feeble emargination in the middle, fine elongate granules giving it a rugulose appearance; frontal carina interrupted in the middle, a curved clypeal carina anteriorly and a conical tubercle behind, genae rather smooth; pronotum ( Fig. 14D View Fig ) fairly strongly, closely but unevenly punctured without well marked median line, front angles not very sharp, hind angles obsolete; elytra moderately strongly striate, intervals finely and sparsely punctured; pygidium and metasternal shield feebly and sparsely punctured; sides of metasternum densely granulate and hairy. Clypeus with smooth minute granules giving it a rugose appearance; front tibia curved at the anterior tip, mid-femur with a sharp tooth near the end of lower edge, mid-tibia ( Fig. 16D View Fig 16 ) slender at base abruptly dilated near the middle, hind trochanter slightly toothed beneath.

AEDEAGUS (in mm) ( Fig. 8E–H View Fig ). LP=1.5, Lp =1.5; BP= 1, BpB= 0.5, BpT=0.25. Phallobase slightly longer than parameres. Parameres almost straight above, curved below and at the tip, with a curved opening on the ventral side near the base. The margin of this opening where the parameres meet is broader in the middle.

Female

Clypeus closely rugose; protibia broad, narrow with four strong teeth and an articulated spur.
