The species was previously (Steinmann 1986) only reported for Venezuela, but on iNaturalist are observations rom Colombia:

Pygidicrana notigera (only known by female for Brazil and Colombia) has no protruding wings, but in general, the coloration of P. quinquenodosa (only known by male from Venezuela), P. trinodosa (only known by male from Venezuela, see holotype here: https://www.flickr.com/photos/116167668@...157667071340967) and P. notigera is very similar - many specimens from Colombia are on iNat, I believe it's maybe either just two species, a complex of several very similar species or all 3 species are valid, but it's probably too easy to believe in the current state of science as it is.

The differentiation by concealed or absent wings seems to be unlikely, as many species can be apterous, brachypterous or fully winged, variation in forceps shape, pygidium shape, elytrae/hind wings and even the male genitalia are very common, as can be the coloration. Without DNA barcodes it's probably impossible to reveal the Pygidicrana-complex of Colombia and Venezuela.

On iNaturalist I will continue to try to ID by elytral length, wings and dark markings if it's possible, as long as no further research suggest taxon changes - in this case it's easy to merge species on iNat, a separation would be work by hand, but Pygidicrana has not that much observations.

further note: There are specimens, that don't fit any description provided by Steinmann (1986), see:
https://www.inaturalist.org/observations/154460311

And to complicate things even more, here is an observation with an elytral anomaly:

In Ecuador there's a specimen, that's even different from the other three species, either more variation or more species:

As can be seen in the attached image, all 3 species (=Arten) are found in the same region - a further hint for either one variable species or a species complex. The western and eastern mountain range don't seem to be much different in the composition of phenotypes.
