Diagnosis.
Maxillary palpomere IV aciculate (
Fig. 37
). Antennomeres III and IV elongate; VII to X asymmetrical. Mandible unidentate (
Fig. 36
); mola with brush. Galea narrow (longer than wide); brush apical and paniculate (
Fig. 37
). Surface of mentum setose (
Fig. 39
). Anterior margin of pronotum with a bead (
Fig. 1
). Hypomeron without fovea. Prothoracic corbiculum present (
Fig. 78
). Mesocoxal lines present on metaventrite (
Fig. 1
). Metendosternum with stem present. Secondary lines of mesoventrite absent. Abdominal ventrite I without metacoxal bead. Profemoral ctenidium present (
Fig. 79
). Mesotibia with 2 ventral spines. Metacoxae separated. Empodium unisetose.
Comments.
The shape of the ovipositors is useful for both the definition of taxa and as an indication of relationships. Two
types
of spermatheca are found in examined Japanese species: a single one in the
Baeocera curtula
,
B. abnormalis
, and
B. frater
groups, and in
Baeoceroxidium micros
(
Figs. 58, 59
), two in the
Baeocera monstrosa
and
B. satana
groups (
Figs. 60, 61
).
A patch of spines is present on the inner surface of elytra (
Fig. 82
), and is assumed to be associated with wing folding (Nomura 1997).
