Something of a mopping-up exercise here, comprising three groups of mammals which we are yet to look at in this series of photographic guides and which are all somewhat close kin.

It seems reasonably clear that these groups belong within a larger monophyletic clade - termed the Euarchontoglires - along with two other groups which have already been dealt with elsewhere; however, the precise interrelationships between the various lineages within the Euarchontoglires are still rather less clear. Certain aspects of the overall taxonomy seem reasonably sound; the lagomorphs (Lagomorpha) belong within a clade termed "Glires" alongside the Rodentia, whilst the colugos (Dermoptera) belong within a clade termed "Euarchonta" alongside the Primates. However, there are multiple competing theories about the placement of the treeshrews (Scandentia).

The traditional view - and the one which, for the sake of parsimony, we will follow here - is that the Scandentia also belongs within the Euarchonta, in a position basal to the primates and colugos. However, genetic and morphological studies have proposed a number of alternate hypotheses:

  • Tree shrews represent a sister group to the colugos, forming a clade within Euarchonta distinct from the Primates.
  • Tree shrews belong not in the Euarchonta, but within the Glires in a position basal to the rodent/lagomorph clade.
  • Tree shrews are basal to all members of the Euarchontoglires, and arose prior to the split between Euarchonta and Glires.
Given the fact that it seems clear that they are morphologically similar to the common ancestor of the Euarchontoglires, and doubtless arose early within the history of this clade, regardless of where they belong taxonomically it may well be impossible to conclusively determine the correct state of affairs.

What are you using as your source for subspecies distributions? According to (e.g.) Menon's Indian Mammals and Srinivasulu's South Asian Mammals, only the nominate is found in India (e.g. at Ladakh where the photo was taken). O. m. wollastoni is from about Nepal eastwards.

HBW, which cites the following ranges (transcribed verbatim)

O. m. macrotis - Kunlun Mts in Xinjiang, Tibet {=Xizang) , and Qinghai, W China
O. m. chinensis - NW Hengguan Mts in SE Xizang, W Sichuan and NW Yunnan, SW China
O. m. sacana - Tian Shan and Pamir-Alay Mts from SE Kazakhstan to Tajikistan
O. m. wollastoni - Karakoram and Ladakh ranges and Greater Himalayas E of 81° E

That's interesting. I wonder if they have transposed something.

The type locality for O. macrotis is given by Wilson and Reeder as being at 31EN, 87EE in Tibet, which places it just above western Nepal and just east of Ladakh (i.e. directly within HMW's range for wollastoni and well south of their range for macrotis). The type locality for wollastoni seems to be the Mt Everest area, which is well to the east of there (above eastern Nepal).

In other sources sacana may be merged with macrotis (so in that case macrotis would cover the whole western part of the range (in Central Asia)).

It seems like HMW has just extended wollastoni well westwards, leaving sacana / macrotis only in Central Asia / northern Tibet, but in the process have put the range directly through the type locality of macrotis itself which cannot be accurate.

Another option, of course, is the Omani/Humes/Desert Owl situation where the population generally assigned to the type subspecies turns out to be a different ssp to the type specimen, and the population the type specimen applied to turns out to be synonymous with a subsequently-described taxon.

Not sure if there's any easy way of discovering whether a neotype has been assigned however, which would be how to check said theory.

Did anyone ever figure out what the exact situation with Bronx's pikas was? They only ever had 1.1 from Minnesota (same source as Berlin's colony) and prior to that were imported from Mongolia (which wouldn't make them the nominate subspecies), however they had two very different looking individuals.

The individual photographed above I believe was the male, which I remember @Chlidonias noted did not look much like a Daurian Pika. Something to do with the ears I seem to recall? The female on the other hand looked more normal and much more in line with the animals kept at Berlin.

Below are the four available photos of the male:
Daurian Pika - ZooChat
Daurian pika (?) - ZooChat
Daurian pika (Ochotona dauurica) - ZooChat
Daurian pika (Ochotona dauurica) - ZooChat

Don't know if you're gonna use photos of stuffed animals in this thread but if you do then a photo of the Altai pica - Ochontona alpina is already in our Gallery ( Germany - others ) :
