[Banshee05]

The Heterophrynus species from Colombia got a name, Heterphrynus javieri Seiter & Gredler, 2020.
The paper will appear soon. See here...

Sexing Phrynichidae: note the red hairs around the genital operculum in females

Euphrynichus bacillifer female

Euphrynichus bacillier male

I have done a collage of genital operculum from three species, if it can help!

@JordanC Thank you. That's fantastic!

nice shots. Much better than mine. As I did it just on request I thought to post it here as well. Sexing is always an issue, and with Phrynichidae and some others pretty easy in all stages.

Thanks!

More shots, spermatophores this time.

Very cool! Haven't seen a lot of pictures of these, and certainly no good ones and nothing organized by species.

 

[Banshee05]

the Catageus spermatophore look like C. longispina. If it is from Malaysia I would bet on it, as I got the same. You clearly see all the differences in the shape and form. I am currently working on a revision of that. Pretty exciting.

Spermatophore of Phrynus longipes

 

[Banshee05]

you make awesome shoots!
the sp look emtpy, even if from the poterior view.

 

[JordanC]

Thank you!

And thanks for the info, how do you tell it looks empty? Because it's translucent? Few hours after i took the picture there was no more spermatophore, only the basis of it.

 

[Banshee05]

because longipes SP does have large lateral horns, facing anteriorly, so tha direction where the female first approach the SP. So this seems to be the side we cannot see on your pictures,if the horns do not protrude prominent, at the least the female handeled the SP somehow, also the sperm mass itsef (spermatozoa) are more in the middle section of the head, most of the time looking quite "dark" white.

 

[JordanC]

Ok i see about the horns, it must be quite similar to Phrynus marginemaculatus.

A recent video i took of Phrynus marginemaculatus by the way, where we can see the spermatophore.
