Tragidion - Tragidion densiventre

I believe...

...this is the male of Tragidion densiventre, based on the light red-brown head, pronotum, scape and legs, the elytra narrowed to the apex, the costae somewhat curved inward to the suture, and the narrow black basal band on the elytra. This species occurs in lower desert habitats, while T. deceptum occurs at higher montane elevations, although the two species can co-occur (even feeding on the same shrubs) in zones of contact.

Immature specimen

of T. peninsulare californicum Linsley, 1940 (probably).
Type (female) at:http://plant.cdfa.ca.gov/byciddb/details.asp?id=6704
I have some doubts about the taxonomic status of these "subspecies"...

Tragidion annulatum

It looks to me to be a typical male specimen with the annulate antennae and the fulvus coloration. The female is the more typical red-orange color. Male T. peninsulare are the same color as the females.

Which the difference?

The annulatum type (http://plant.cdfa.ca.gov/byciddb/details.asp?id=6680) has the antennomeres
VI darkened at the apical half,
VII-XI black

while the peninsulare type (http://plant.cdfa.ca.gov/byciddb/details.asp?id=6702) has the antennomeres
VI darkened at apex,
VII darkened at the apical half,
VIII-XI black

The antennae of this specimen seem more similar to those of the latter species.
I have no keys at the present, but according to which characters you have decided this species is annulatum?

… Francesco Vitali, 7 December, 2007 - 2:00am

I agree

I wanted to have it sorted into annulatum, but some editor must have overwritten!

Please unlink.

Linked images are supposed to be for the same exact SPECIMEN, not species. This series is further confused by the two different localities. Don't worry, I won't tell anyone else:-)

The others are the same specimen

from the group shot of the couples.
