On this #tenebtuesday — a favorite teneb (& favorite photo of a heap of 'em), Neomida bicornis (Fabricius, 1777) [Diaperinae: Diaperini]? Their pronotal coloration is variable, from shining metallic green in some beetles to red in others, & the males have two tiny horns!

And this #TenebTuesday an answer (at last!)—this is the rarely collected Prateus fusculus LeConte, 1862, a member of the subfamily Lagriinae & type genus of the recently-established tribe Prateini (Aalbu et al. 2023)

A mystery teneb for this #TenebTuesday — specimen collected by Charles Dury in Cincinnati &, until last month, was only identified as "'Tenebrionidae unknown' teste [George Henry] Horn" — any guesses?

But this is going to be yet another area where the taxonomists who did all the work to set up the species and the traits to identify them don't get paid. Even as many are retiring or losing their jobs, the resources get diverted away from expertise to the tech sector instead.

And for #TenebTuesday here’s Strongylium crenatum Mäklin, 1867—this species is widespread in the southeastern US, but can separated from the other co-occurring Strongylium by its iridescent green coloration, punctate elytral striae, & indistinct, crenate pronotal margins

For #WeevilWednesday — a 106-year-old specimen of an anthribid, Toxonotus fascicularis (Schönherr 1833), described by its collector, Willis Blatchley, as "a prettily marked medium sized anthribid frequent on the dead branches" of saffron plum, Sideroxylon celastrinum.

Doyen & Lawrence (1979) note “Edrotes [Pimeliinae: Edrotini] (North America) & Epiphysa [Pimeliinae: Adesmiini] (southern Africa) are strikingly similar in external appearance [but] major differences in endoskeletal features, mouthparts & genitalia refute a close relationship" #TenebrionidTricky

Back from an end-of-semester-hiatus here's Epiphysa ciliata Bates, 1872 (Pimeliinae: Adesmiini) for this #TenebTuesday —1 of 9 distinctively globose spp found across arid southern Africa. They are “crepuscular to nocturnal,” retreating to “rocky crevices or mammal burrows” in the day (Penrith 1978)

This specimen has been in @purdueentcoll.bsky.social for nearly 130 years — but has only two minute labels reading "Marquette, Michigan" & "H.G.H." [Henry Guernsey Hubbard] — Hubbard collected extensively in the Lake Superior region in 1876 (Mallis 1971), making this specimens over 149 years old!

Back from an unintended break — for this #TenebTuesday here's very typical (looking) #tenebrionid — Bouchardandrus concolor (LeConte, 1866), only species in the genus & only known to from the Great Lakes region of Canada (MB ON QC) & US (MI MN OH WI) (Steiner 2016, Bousquet et al. 2018)

This specimen was collected by W.S. Blatchley —his brief label says “R.P.P. Fla. ... 3-25-24”—but in an unpublished manuscript, “Winter & Spring Insects of Royal Palm Park,” he included more details (under the synonym N. viridimicans)—beetles were “beaten from dead limbs” #PERCBugs #TenebTuesday

A composite image showing a pinned beetle specimen, its labels, and a manuscript excerpt. The labels read "2661, R.P. Park Fla, W.S.B. Col, 3-25-24, 7547, Helops viridimicans, Horn" and the manuscript excerpt reads "463 (12449) Nautes viridimicans Horn—One, December 14, beaten from dead limbs near west edge of hammock; another in March from the same place. Known only from Florida and new to my collection."
