Today my magnificent octopus magnum opus, a 126-page monograph on the genus Rhombophryne—Madagascar's diamond frogs, was published open access in the journal Vertebrate Zoology. In it, my colleagues and I have described seven new diamond frog species and provided detailed revised accounts of each of the now 27 species in the genus, compiling practically everything that is known about these curious and obscure frogs!
Allow me to introduce the new characters:
This piece of lint precious child is Rhombophryne maraorao, a little burrowing species from the northeast of Madagascar. It is very similar ecologically to R. coudreaui, a long-known species from further south. The name maraorao means ‘rough to the touch’ in Malagasy, referring to the rough skin of this species. They do a weird thing where they straighten all of their limbs and go stiff in self defence. Think pumpkin toadlet post-launch mid-air stiffness, but… in the hand?
This beautiful creature is Rhombophryne mavokely, a little leaflitter-dwelling species from the northeast of Madagascar. The name mavokely is the Malagasy word for ‘pink’ but literally translates as ‘small yellow’ (mavo = yellow, kely = small). I LOVE this bizarre etymology, and also this species is small and sometimes pink and sometimes yellowish, so the name seemed extremely apt. This species was the first Rhombophryne I ever saw alive—I caught the first ever specimen immediately underneath my hammock on Marojejy in 2016!
This shiny boy is Rhombophryne sonaliae, a rather well known species from eastern Madagascar that has previously been called R. alluaudi—until we showed in 2019 that the correct use of that name was for a Plethodontohyla alluaudi from southern Madagascar! We dedicated this species to Sonali Garg, in recognition of her fantastic work especially on Asian frogs.
This forbidden truffle is Rhombophryne anatiala, a very poorly known species very closely related to R. sonaliae but found further north and differing subtly. The name anatiala means ‘in the forest’ in Malagasy, referring to the forest habitat of these frogs.
This bumpy beanbag with his go-faster chevron is Rhombophryne kotrobaratra, an interesting species from northeastern Madagascar with rather unusual anatomy, especially its quite long and strong hindlimbs. The name kotrobaratra means ‘thunder and lightning’ in Malagasy, and refers to the inclement weather that seems to bring these frogs out (true for all Rhombophryne, really) .
This coffee bean is Rhombophryne quentini, an orange-thighed species from high-elevation forests in northern Madagascar that resembles R. ellae. Back in 2020 I named R. ellae after my partner, Ella, and I thus took particularly great pleasure in naming this new, closely related species after our four-and-a-half year-old son, Quentin. A little family of frogs. :3
This little pebble is Rhombophryne kilonjy, a small, poorly known and obscure species related to R. ellae and R. quentini but found in lowland forest close to the coast in northwestern Madagascar. The name kilonjy means ‘pebble’ in Malagasy because, well, just look at it.
Even way back in my tumblr posts from 2013 and 2014 I think you would find mentions of the work I had begun on this monograph. I had no notion that it would take more than twelve years to complete. But I cannot express my joy at finally being able to share these charming, round frogs with the world. I hope you approve of the names!
If you want to read a bit more about these frogs, you can do so on my website. I have even posted a couple short videos about them on TikTok and Instagram (which also will show you how to pronounce the names!). Basically, you can find me most places on the internet, and wherever you find me, you can be sure to find frogs and lizards and snakes and a good deal of enthusiasm.
