Scientific researcher, focused on various aspects of biodiversity for Neotropical insects and arachnids.

@plazi_species - How should users report processing errors - in this study the species is given authorship of 1914, yet it was described in 2008 by two authors who are both very much alive! https://t.co/y6fJxjbuln

@AlyxG @LizyLowe Why add the alarmist word 'horrific'? The aracnophobe of the referenced ABC article does not get quoted there as saying that, so where is it from? You added it? Cmon, it needlessly vilifies spiders, again.

Quality bird thread.

[Stuart Longhorn @StuartLonghorn]

@ThomasShahan Great shots yet again. You’ll get yourself in trouble with some Araneidae focus arachnologists by including the Photo of a Trichonephila under this family.

Some great photos again by Thomas Shahan

Some more araneid diversity from Oklahoma: a pointy Acanthepeira, a cute Mastophora phrynosoma bolas spider, a contrasty Micrathena gracilis, and a handsomely patterned Verrucosa arenata

[Stuart Longhorn @StuartLonghorn]

@FabioAleRomero @ArminReindl It was Erginulus subserialis, a species widespread on pacific lowlands of Central America from Chiapas Mexico to Guanacaste Costa Rica. You had the right family. Most species are really poorly known, and many undescribed ones, but this one is especially widespread.

@Arachno_Cosas @andrade_5540 Es Cupiennius salei, sin dudas. Saludos

[Stuart Longhorn @StuartLonghorn]

@ThomasShahan Awesome observation. For the record, the spider was Olios simoni, currently known from just one female specimen from Guatemala in the 1880s. I’ve seen a fair few photos from Belize, so not rare, but the male is undescribed and ecology etc is completely unknown.

Outraged but not surprised that my employer (I'm a grad student), the American Museum of Natural History, is hosting a $30,000-a-plate Gala in honor of the fascist and genocidal Brazilian president Jair Bolsonaro, a man who is forcing Indigenous peoples off their land...

@AMNH Your option is to put dignity and respect for science and biodiversity in front of money that you’d gain from an event that honours a grubby politician.

I think my Red-knee tarantula is trying to tell us something for Valentine's day? I expect it is love for the Commission for Environmental Cooperation’s ground-breaking work to help end illegal trade of North American tarantulas! https://t.co/IFHGglJ5zb

[Stuart Longhorn @StuartLonghorn]

Each year, thousands of tarantulas are traded to meet the demand in the live pet market. As a result, many are being depleted from the wild.

Today is a sad day for #conservation science and for all the other fields which rely on museums, as the National Museum of Brazil in #RiodeJaneiro is destroyed by fire and with it its unique collections. Our thoughts go to our colleagues #MuseuNacional

@NateTWN @weathernetwork But none of Guatemalan scorpions are dangerous. Please get museum to contact Ronny Trujillo (see above), so do a proper study of identity.

@realDonaldTrump and when a dictator equates his own will is that of the country - HUGE trouble!

[Stuart Longhorn @StuartLonghorn]

@Bombus_lucorum Not in this case, these have a dome like proturberance in the middle of its head, and people only guess at function.

#bestcarcass. Syntype specimen of Costa Rican horned tarantula Sphaerobothria hoffmanni Karsch, 1879. Doesn't look a day over 135 years old!

[Stuart Longhorn @StuartLonghorn]

@realDonaldTrump Terrible response. At an appropriate time (end of THEIR show), they courteously shared their voices a moment longer. Listen
