Classification 叩頭蟲科(Elateridae)
|
|
Diagnosis
Length 3.3-3.5 cm in male, 3.5-3.7 cm in female; dorsum
of prothorax metallic green or greenish blue, with two
lateral orange bands; ventral view of prothorax dark metallic
blue, with two lateral bands; elytra usually metallic
green or somewhat metallic yellowish green; ventral view
of abdomen dark metallic green, with two broad red lateral
bands. |
|
Distribution
According to Suzuki, this species (or species complex)
is only restricted to Taiwan. |
|
Habitat and Ecology
This species complex inhabits in the primary forests from
low to medium elevation. The adults are day-flying and
seldom attracted by light. The ecology of this species
complex in Taiwan has never been surveyed. For further
ecological information about this genus see Ohira &
Fukaishi (1999). |
|
Threats and Conservation Status
Status This species complex is not very rare in the wild
and has many related species ranging throughout the surrounding
areas of Taiwan (Li & Yang, 1997). However, due to
their brilliant colouration, this species may be threatened
by over-collecting and deforestation. |

Remarks
According to Suzuki (1999), the so-called "Campsosternus
gemma" from Taiwan are in fact composed of two
resembling species, which are distinct from the true
Campsosternus gemma Candeze (朱肩麗叩甲)(Figs. 197-199)
from northern China by subtle morphological differences.
In his study, Campsosternus gemma watanabei Miwa
(Figs. 200-201; see also Chang, 1999) was upgraded to
species status--Campsosternus watanabei Miwa
(渡邊青叩頭蟲、渡邊虹彩叩頭蟲). In addition, he stated that an undescribed
species (Fig. 202) has been identified as Campsosternus
gemma in various literature (e.g. Kishii, 1995; Wang,
1993: 90-91; Lien, 1999: 129; Chang, 2000). Before his
forthcoming study is formally published, we suggest to
treat this species as a species in broad sense without
changing its status in the protected species list. |
