Scaphobaeocera
Csiki, 1909
Comments:
Currently, 94 species of
Scaphobaeocera
are recognized as valid, most of them occurring in tropical and subtropical Asia. The range of the genus is, however, extended northwardly to Far East
Russia
, and to Queensland and Subsaharian Africa in the south.
Scaphobaeocera kraepelini
(
Pic, 1933
)
from Java is the sole so far mentioned Indonesian species, and for practical reasons redescribed below. Most members of this genus possess elytra with distinct parasutural striae, unknown in other scaphidiines, any many have elytra, eventually also other parts of the body, iridescent, a character state rather unusual in other genera of the subfamily.
