Greetings,

I am a Systematic Entomologist that specializes in the ecological interactions and evolutionary trends of Hemiptera: Tingidae. Follow me for beautiful bugs and exciting stories—an alumnus of #UND and #NDSU. Currently a free agent!

Happy #TingidTuesday, I'm currently at the AMNH Southwest Research Station looking for tingids! This week, I have Teleonemia consors Drake. This species was described from Bonita Arizona and can be found in several sky islands of the American southwest. The host plant is unknown. However, I just collected a nice series of adults and one 5th instar nymph from Garrya wrightii Torr. Wrights silk tassel #Garryaceae.

Happy #TingidTuesday everyone! Sorry for the long lapse in posts! Here is Ambycysta championi (Drake). This species is the type of Ambycysta that was first described from #Brazil and has yet to be reported elsewhere. This specimen from
TAMU Entomology.

How about another #TingidTuesday! Here is Dicysta vitrea Champion, the type species of the genus. This species was described from Panama. Later reported from Brazil, Paraguay, and Peru. Hosts plants included several different species of vining #Bignoniaceae. This specimen was collected near Chapada dos Guimarães, #Brazil by Herbert H. Smith. Specimen from CMNH. #Tingidae #bugs
Welcome to another #TingidTueday, Here is Nyctotingis cf. osborni Drake, the type species for the genus. Described from one specimen from Chapada, #Brazil. Subsequently reported from Ecuador & Peru. The only known host record is #Bamboo. Specimen from Monte L. Bean Collection at BYU. #Tingidae #bugs.
Happy #TingidTuesday everyone! Here is Baeotingis ogloblini Drake and Poor, the type species of the genus. Which was described from Argentina and reported from Brazil in 2014. Specimen from the Drake Collection at USNMNH Entomology.
The Vianaidinae have long perplexed entomologists and the earliest known species was actually described as a Lygaeid. These pink to red-brown bugs are only found in the neotropical region of the world and have been collected in caves, soil, leaf litter, and ant nests. Marcus Guidoti and colleagues recently studied this group phylogenetically, revised this subfamily, and described several new genera and species.

For #TingidTuesday I have Annomatocoris zeteki Drake & Froeschner. This species is a member of the obscure and rarely encountered subfamily Vianaidinae. Their biology is poorly understood but they have been documented as #myrmecophiles. Specimen from USNMNH Entomology.

Here, here for #TingidTuesday! Meet Corycera panamensis Drake & Poor. This species was described from #Panama and later collected in #CostaRica. The only known host records are #banana or Musa sp. This species is native to the neotropical region, but #Musaceae is not. Therefore, C. panamensis may also use the Neotropical species of the Zingiberales. Specimen from
@OSUCatOSU.
Happy #TingidTuesday, I’ve been busy with job applications, manuscript reviews, and much-needed family time. Here is Dyspharsa uniseriata Cazorla & Knudson 2021 which was described from Trujillo and Merida states, Venezuela. 📷 from Cazorla & Knudson 2021. #Tingidae #Bugs The only congener, D. meyersi (Drake), was described from the Trinidad mountains in Cuba, not the island of Trinidad as listed by Drake and Ruhoff (1965). I can provide an English translation of the original description.
For #TingidTuesday I have Agramma atricapillum (Spinola). This species is found in Southern Europe, North Africa, parts of the Middle East, #Ukraine, & surrounding countries of the Black & Caspian Seas. This species feeds on monocots like Juncus, Typha, & Scirpus. This specimen was collected by Horsák & Kment in 🇨🇿 and is from the National Museum of the Czech Republic, Praha. #Tingdae
