Tapinauchenius violaceus L7
Wondering male or female?
I would guess at male but you need a moult to be 100% venting isn't accurate.
I’m learning. Do my observations match yours? I see a straighter line but not the dot/triangle in the middle. Still, I’m leaning male because of the straighter line. Is that your take?
 
I can also see a hollow just above the furrow (slit) in-between the book lungs, it's like a dipped in arch but yes the furrow is also very straight females tend to have a bulge above the furrow and a furrow it's self is smile shaped. @NMTs @vicareux @The Spider House what do yous think ? But I am pretty sure that your t looks male. As I said moult to be sure though.

I agree with male. The furrow is mostly flat, and there does seem to be an upside down horseshoe-shaped patch of darker setae above, as well - which could be the epiandrous fusillae. Or, it could be a female that is so young it just hasn't developed yet and we're all wrong! Lol. OP - please update when you get a molt.
