| Species: | Fringed Larder Beetle (Dermestes frischii)| This Photo: | 🔍S1, Front Leg🔎 | Thank you Goro (Saber_Animal) for identifying and Aron Bellersheim (ColeoManiac) for helping with the id of this species for us General Species Information: Found on Ellura (in the Murray Mallee, SA) and elsewhere ~9mm long. The larvae of these are used in forensic pathology. We didn't get a detailed shot of the end of the elytra so weren't able to differentiate between D. maculatus and D. frischii. We asked Aron if he could provide some diagnostics for these, he kindly replied "Dermestes habitus: First, it differs in shape with its long-oval body outline and its slightly rounded cross-section. The body below takes up half of the hight and is not flat and fully enclosed sideways by the elytra. For identifying beetles it is always useful to have a good look at the antennae. In Dermestes there is a 4-segmented bulb with the first segment often very short and wide. If you would be using a dichotomous identification key Trogositidae and Dermestidae would be differenciated by something like if the front coxae are protruding higher than a mesosternal spur." When asked how they differentiated between D. maculatus & D. frischii, Goro said "The 'Abdomen, profile' photo is more than enough. The stripes and markings, the two ocellates and their position... etc. The only thing that may confuse a little is the ventral mark of the last segment, which, being more worn, may confuse a little with the maculatus shape."
