The Most Rarest, Ancient Ants and The Quest to Rediscover Them

Australia is home to a wide range of ant species. One that might spring to mind is the Bulldog/Jack jumper ant, genus myrmecia.

(M. gulosa, "Hoppy Joe!")

As you can see, these ants have quite big eyes. This is because bulldog ants are very dependant on vision, something most other ant species have replaced with pheromonal (scent) trails.

But we aren't here to talk about them. We're here to discuss their cooler, shady cousin,

the Dinosaur ant (Nothomyrmecia macrops).

They might look all cute, but they are much more than that.

These ants are possibly the rarest and most primitive of all ant species, and this shows in their behaviour.

Like the Bulldog ant, these ants rely only on their vision as apposed to pheromones. Colonies only range from 50-100 individuals, when most ant species have colonies in the thousands. Furthermore, queens only lay one generation of eggs every year!

Because of this small size, workers can not effectively compete with other species such as Camponotus and Iridomyrmex. Thus, these ants are exclusively nocturnal so they don't have to hunt alongside the diurnal ant species.

Infact, the Dinosaur and Bulldog ant are so similar that the Dinosaur ants genus name, 'Nothomyrmecia', means 'False Bulldog ant'. The species name, 'macrops', means 'big eyes'.

--------------------------------------------------

This species was first discovered in the form of two worker specimens by Amy Ena Crocker and colleagues, supposedly inland from Israelite Bay in Western Australia.

Due to its primitive appearance and unique body shapes, scientists were eager to find more specimens. Many expeditions were set out to locate this ant over the next three decades, all of which failed. One of the more notable expeditions was lead by the late, the great entomologist E. O. Wilson (who literally invented sociobiology!!!)

However, on October 22, 1977, entomologist Robert W. Taylor and colleagues would rediscover a lone worker in Poochera, South Australia. I'll let nullarbor.net take it away:

"Spurred on by rumours that an American scientist was coming to search for the lost ant, Dr. Taylor apparently mounted one last ditch attempt to beat the Americans to the punch. By an incredible stroke of good luck - if it could be called that - Dr Taylor and his group were driving to Western Australia when their vehicle struck mechanical problems at Poochera. As we all know, even the best laid plans can go astray, and Dr. Taylor's expedition was forced to make an unscheduled stop, and camp for the night at Poochera.

"Later that evening Dr. Taylor conducted an impromptu insect survey in the mallee scrub adjacent to camp. There's no doubt the last thing on Dr. Taylor's mind was Nothomyrmecia - after all, the last and only recorded sighting was made 46 years earlier, and even that was fully 1300 kilometres away to the west. Poochera was definitely the last place where Dr. Taylor expected to find Nothomyrmecia - but there it was, one solitary Nothomyrmecia worker ant crawling on a eucalyptus tree trunk.

"The sight was truly astonishing. Dr. Taylor then rushed back to his colleagues and in true Australian style he announced to the world, "The bloody bastard's here! I've got the Notho-bloody- myrmecia!"

I'd like to imagine that's true.

Poochera, which features Nothomyrmecia abundantly in the streets, is perhaps the only town I know of that survives exclusively off of ant tourism.

See you soon.

 ABSTRACT This paper formally names a new species of viper from Croatia, Europe as Pelias cathrynmatteoae sp. nov.. This range-restricted taxon has been known as distinct for some years. It is most closely related to Pelias ursinii Bonaparte, 1835, a species placed by most publishing authors in the genus Vipera Laurenti, 1769, or alternatively the nominate taxon best known as Vipera ursinii rakosiensis Mehely, 1893, herein treated as a full species, that being the next most closely related species. The putative taxa Vipera ursinii macrops Mehely, 1911 and Vipera ursinii moldavica Nilson, Andren and Joger, 1993 are treated herein as subspecies of Vipera rakosiensis based on their limited divergence from that taxon, but all are also included herein in the genus Pelias Merrem 1820. P. cathrynmatteoae sp. nov. as formally named herein has also at times been confused with putative P. ursinii macrops Mehely, 1911. P. cathrynmatteoae sp. nov. (type locality Velebit, Croatia) is split into two subspecies with P. cathrynmatteoae kapelaensis subsp. nov. occurring in the Kapela Range (part of the northern Dinaric Alps). A subspecies of P. ursinii from far south-eastern France, east of the Durance River is also formally named for the fi rst time as P. ursinii alpesdehautensis subsp. nov.. It is a distinctly different subspecies to the previously named P. ursinii wettsteini Knoepffl er and Sochurek, 1955, with a type locality of den Montagne de Lure, Bases Alpes, south-east France and occurring west of the Durance River. The southern population of P. graeca (Nilson and Andren, 1988) is formally named as the subspecies P. graeca vardousiaensis subsp. nov.. With limited distributions, combined with a strong interest in vipers among herpetologists, it would make sense for viable captive populations of the relevant taxa to be established to protect against unforseen calamity or event that may exterminate those in the wild.

I read somewhere that rain frogs are mostly muscle, is this true? Extremely curious about their anatomy so I'm wondering if you have any insight as to why/how they are so round!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Yes, you are correct, Rain Frogs are actually not altogether that fat... they're just shaped like that. They actually do have quite a lot of muscle mass for their size.

Having a round, compact body seems to allow for better, more efficient, burrowing.

You see, that "fat", round body again and again in different groups of burrowing frogs, like many of the Microhylidae and the Spadefoots. This group of frogs does seem to be the ultimate in roundness though!

For a more technical explanation of how they're structured, check out Mark Scherz's recent post about the subject...

Desert Rain Frog (Breviceps macrops), family Brevicipitidae, South Africa

A few herpetologists are now including rain frogs (and their close relatives) in the family Hemisotidae, as the subfamily Brevicipitinae. I am not, though the 2 families are now considered to be very closely related.

Which frog is Most Round?

No question, members of the genus Breviceps. They are basically balls of pure muscle. Which species is more challenging. Contenders include

Breviceps mossambicus

B. gibbosus

B. fuscus

and

B. verrucosus

All extremely round.

Note 1: I do not include some of the other Breviceps here, like B. macrops, because they have more distinct heads and larger eyes that break up the roundness.

Note 2: I am defining roundness here as being as near to spherical as possible, not just a circle. If we were going just circular/disclike, there would be many other possible contenders, and Glyphoglossus molossus would be a very possible winner.
