My population of Schizomida (parthenogenic tailless whipscorpions) are so happy in their box of dirt. As always, tending a box of dirt is such a good decision and I recommend it.

This extinct schizomid from Dominican amber is one of the few extinct species described in this order as of yet. The only described specimen is extremely well preserved, to the point it was easily determined it was a female. Size : around 5mm of body length Time period : Early-Middle Miocene Paleoart speculativometer : Almost a carbon copy The animal drawn is a schizomid, an eyeless arachnid walking on 6 legs and using its first legs as antennae

While not my best shot, arguably one of my coolest finds from the tropics, what is very likely the first identifiable live photo of Surazomus selva! A schizomid found along the atlantic slope of Costa Rica in lowland rainforest, as the name suggests described from La Selva Biological Station

Subterranean - Troglofauna

Troglofauna are creatures that live in caves and small spaces underground.

They tend to crawl or jump around instead of fly because they have no eyes or wings. Typically they have reduced or no eyes and navigate the dark with other means. 🎨 🐡

Story time: one time I found a new species unknown to science during #InverteFest in Dec 2021.

This thing that looks like a weird, long spider is called a schizomid, also known as spricket (short for spider cricket). Schizomids are obscure, understudied arachnids most people have never heard of.

You know the drill, let's first talk about this species naming history, morphology, distribution and life cycle of this schizomid.

Hubbardia pentapeltis is one of the first schizomid species to have received a scientific name. It was given by Orator Fuller Cook Jr., an American entomologist, in 1899, 46 years before the name Schizomida was coined. This species has also received other names through decades of research, having been housed sometimes under the genera Trithyreus or Schizomus. However, due to zoological naming rules, Hubbardia remained the preferred genus to name this animal. Hubbardia pentapeltis is a 1-ish cm long arachnid, and as one of the first schizomids to have received a name, is often used as a classic template of the schizomid body plan. The animal is eyeless, with elongated antennae-like first legs, 6 walking legs and an opisthosoma ending with a short flagellum, looking almost like a miniature eyeless vinegaroon. The similarities stop here however, the flagellum of schizomid being rather short, pedipals opening in an up-and-down move (while vinegaroons open their pedipalps to their side) and the prosoma’s carapace is divided into 3 sub-parts, all these features being observable on H. pentapeltis. This species is also a good example of how sexual dimorphism works among schizomids, males having a kinda triangular broad, fused and enlarged flagellum (not looking so much like a flagellum in this case tho) whome females preserve a more simple flagellum. Hubbardia pentapeltis is endemic to California, the first described specimen coming precisely from Montenery County in the Los Padres National Forest, at the South of Los Angeles. Observations related to this species can be a bit scarced (and no particular distinction between males & females can be noted), but most of the available data highlight a decrease in activity during Northern Summer.

Now that March Mammal Madness has branched out to every critter & some plants, in the 2024 edition there was Draculoides bramstokeri & it was very cool learning about a Schizomid! I agree more people should know about them.

Antillostenochrus pseudoannulatus is one of the schizomid species named from Dominican amber, a fossil resin coming from mines mostly in the North of the Dominican Republic, one of the two states with Haiti making up Hispaniola island (the 2° largest island of the Caribbeans after Cuba). This species was first assigned to another genus and named Mayazomus pseudoannulatus in 2010, even tho this identification was already questioned by the ones who gave it. It was renamed 1 year later in 2011 as Antillostenochrus pseudoannulatus, the genus Antillostenochrus making more sense both according to morphology & biogeography. his schizomid lived 20 to 15 million years ago, during the first half of the Miocene when a climate optimum made the climate even warmer & wetter than today’s Hispaniola. A. pseudoannulatus lived on the ground of tropical forests where numerous trees grew, including a legume amber tree named Hymenaea protera, which resin turned into the the Dominican amber. The slide also comprise a map of north america 15 million years ago (no ice cap but apart that it looks roughly similar to today) with a pictue of a tropical forest in Hispaniola today, & a paleoart of Hymenaea protera, looking like a fin tree with numerous branches ending with foliage looking like small bushes Antillostenochrus pseudoannulatus is a 5 mm long arachnid exhibiting the classic schizomid body plan. The animal is eyeless, with elongated antennae-like first legs, 6 walking legs and an opisthosoma ending with a short flagellum, looking almost like a miniature eyeless vinegaroon. The similarities stops here however, the flagellum of schizomid being rather short, pedipals open in an up-and-down move (while vinegaroons open their pedipalps to their side) and the prosoma’s carapace is divided into 3 sub-parts, all these features being observable on A. pseudoannulatus. The highly detailed preservation, thanks to the amber contenant, allowed scientists to observe the specimen from every angle just like a living specimen. Minute details, such as the precise form of the pedipalps, are useful to compare this species with modern ones, and the specimen was preserved well enough to be confirmed as a female individual.

The Chief Artificer bristled at the admiration that filled the Savant’s voice as he examined the Schizomid drone. These were beasts, dammit! Not to be admired like a well-crafted suit of protective armor!

I think people (including myself) fail to realise just how diverse arthropods are! I was recently humbled when attempting to ID a Schizomid - a distant cousin of an arachnid group I’m very familiar with - and was presented with the beautiful and thoroughly incomprehensible word ‘propeltidium’.

This species is among the several fossil species showing how much geogrphy shaped schizomid's evolution, and as always, the usual paleoart autofeedback (it's the first paleoart of this species!) and refs!

Thank you for reading & I’ll see you on the next #Cheliceratime!

Schizomids are close relatives of vinegaroons, to the point they both were considered to belong in a single order a century ago. A. pseudoannulatus is a member of the family Hubbardiidae, the most prolific family of schizomid, housing species both in the Americas and in Asia. American species form a grade in which Antillostenochrus pseudoannulatus takes part, said grade from which emerged Asian species. Like several other arachnid orders, the phylogeny of schizomids shows a clear split between old & new world species and seem to have been heavily impacted by Pangea break up. The slide also comprise a phylogenetic tree showing the american Hubardiidae forming a large grade from which the asian species descended. The schizomids of dominican amber Antillostenochrus pseudoannulatus is far from being the only schizomid known in Dominican amber. In fact, with Rowlandius velteni and several undescribed specimens, it seems that this order was already thriving at similar levels as today in the Carribeans. A. pseudoannulatus & R. velteni also provide evidence that 2 of the most widespread carribean schizomid genera were already well diversified 15 million years ago. This suggests, like it’s the case with extinct & extant amblypygids from the Hispaniola island, that the current Carribean arachofauna is potentially the direct offspring of the arachnids that lived here several million years before. Is this paleoart accurate ? To my knowledge it’s the first paleoart of this species, so I tried my best thanks to the detailed description of the species! Colors were chosen both by taking modern Antillostenochrus species as reference & by looking at the sclerotinisation levels of the fossil. Since no eyes are known & that visual refs for the chelicerae weren’t always clear, I choosed to place the first legs and pedipalps like that to hide these areas. This part (second & third legs bases) is taken from general Antillostenochrus morphology. REFERENCES · de Armas L.F. & Teruel R., 2011.
