Herman's Catalogue of Staphylinidae



I received my copy of Lee Herman's catalogue in early 2002, while still a graduate student at the University of Kansas. I was actually too shy to write Lee and ask for a copy so Michael Engel did it for me. I remember thinking that there was no reason Lee would send me - a still unknown entity with just one publication -  a copy, but of course I was wrong.

I think it has been by far the most influential publication in my career. Yes, nothing is perfect, and like any paper it has some errors and omission (Aleocharinae, Paederinae...) but I would have been so lost without this, especially early in my life as a graduate student. I still open the volume that contains the Xanthopygina (the one specially bound in the picture) at least once every week. I think it is fair to say that my productivity would have been significantly impacted (in a negative way) if Lee has not published this work.

The amount of work required to produce something as massive as this is almost beyond comprehension and this is why other catalogues spend so much time in the [unpublished database] stage.

Then again...

I think I am fairly good in self motivating myself to push through projects to completion. Instead of describing two new genera in a simple Zootaxa-style paper, how about we produce a phylogenetic analysis of Xanthiopygina and add all known genera, including these two new taxa? Sure, it will take a year more or so, but it will keep the engine running.

The thrill is gone


One of the biggest challenges for me is to push through a work to publication, when I have figured everything out. Last week I was on Twitter telling the world about how awesome it feels when you finally figure out something -- a unique characteristic that unites a group a three undescribed taxa into a genus.



But then the thrill is gone. I have figured out that this is a new genus. I know that there are three new species. Now I have to show this to the rest of the world. But by this point there is nothing (or almost nothing) new to be discovered. I just have to spend endless hours taking photos, drawing and writing descriptions to persuade my peer community that these are indeed new taxa. But there is very little personal satisfaction in the process and this can slow down the process a bit.

Two new genera and at least five new species. 


When I was starting out as a graduate student, I was trying to maximize the number of papers I could get and sometimes published papers as"least publishable unit". Now I think I am at the opposite spectrum. Last week I submitted a paper where I was reviewing two genera (Dysanellus and Torobus). And for my next paper I seriously consider putting together a description of two NEW genera together.

Figuring things out

Recently I published an new paper describing the genus Phanolinopsis and describing four new species. While writing a paper like that is pretty straight forward once you have figured things out, it usually takes a lot of time to figure things out.

Many many years ago I was visiting a natural history museum examining their collection of Xanthopygina beetles. Among the materials was a specimen of Phanolinopsis erythros.

Phanolinopsis erythros Chatzimanolis
I was puzzled. At that time, I was working on the revision of Nordus and Philothalpus and had finished the revision of Elmas. Let just say that my understanding of Xanthopygina was limited. I asked a Very Important Rove beetle systematist at the museum there what they thought of the specimen and they looked at it and said: "Yes, I have examined it, I could not figure it out, I doubt you will".

Well, they were right in a sense, it took me 11 years to figure it out. I guess what I am trying to say is that figuring out things in taxonomy sometimes takes a very long time. So while writing a taxonomic paper is 'easy', deciding what goes in that paper may take a lifetime. I have been lucky to be able to work with Xanthopygina for ~17 years now, so I had the time to "figure things out". But I am afraid, the way we do science nowadays does not usually allow for having that much time of working uninterrupted* on a project or taxonomic group.

On an unrelated note, on the same paper I named a new species after my daughter.

Phanolinopsis norahae Chatzimanolis
* Over the years,  I have worked on other things other than Xanthopygina, from phylogeography to fossils, but I have never stopped looking at these beetles.

The end of Staphylinidae sensu stricto?

I recently submitted a book chapter on fossil rove beetles where I had the following footnote:

" One could argue that we have overextended the meaning of “Staphylinidae” since the family is not very well defined and the subfamilies themselves can probably be elevated to the family status."

The editors kindly asked me to remove it from the book chapter because they did not want to open Pandora's box (their expression, not mine).

So instead, I am just going to put it here, on this blog.

Over the last several years more and more ex-families (eg Scydmaeninae) are getting sucked into Staphylinidae and one could argue that Silphidae should be added soon. Have we reached the point where we need to evaluate what Staphylinidae really is and perhaps elevate "Staphylinidae" to a superfamily? Unfortunately, for some people this is a numbers game ("the largest family of animals") and I do not see this happening any time soon.

Xenopygus species

Back in November I published a paper in Zootaxa with new species and synonymies for Xenopygus Bernhauer. There are a lot of stories that can be told about this paper and if you are skilled in reading between the lines you can probably guess some by reading the paper itself.

Xenopygus davidi Chatzimanolis
But I want to tell one of the stories here. This is the story of how sometimes we are unable to deal with the backlog of specimens (perhaps data in general) until something happens. For many years I had two new species of Xenopygus awaiting description in my Xanthopygina cabinet. This is not unusual. By a quick count, I probably have ~100 new undescribed species of rove beetles trapped in the cabinet in front of my desk. But taxonomists do not spit out species description despite being urged to do so many times because we want to put these new species into context. That context is typically a revision of a genus, a phylogenetic analysis or fauna checklist.

But back to Xenopygus. I was sitting on these two new species because properly revising the genus meant dealing with thousands of specimens of one of the most common xanthopygine rove beetles, Xenopygus analis. It also meant changing the generic concept of Dysanellus (one of the described species there belonged in Xenopygus). And it also meant dealing with some bad taxonomic decisions made in the 70s-80s.

Xenopygus pycnos Chatzimanolis

So I was waiting until, I do not know, I was ready to deal with them. The Xenopygus manuscript was probably no. 7 in my "in preparation" manuscripts. Well, that changed when Caron et al (2016) published a paper revising Xenopygus. I was not aware of that paper until it came out in Zootaxa. Which was unfortunate, because I would have told Caron et al. about all the problems mentioned above. Caron et al. published two new species that ended up being synonyms of taxa that had been described before. To their defense, it was almost impossible to figure this out unless they had seen photos (or examined) of every single species in Xanthopygina. But on the plus side, they dealt with the revisionary aspects of X. analis and that allow me quickly to publish the two new species and regrettably to synonymize the species they described as new.  

I guess the story here is that we all need motivation in our lives. Sometimes motivation to finish that manuscript comes from places we do not expect.

It’s not a plant!

It started as a joke. For a couple of years it was the number 1 item in my to do list  on the lab whiteboard: “Revision of Smilax”. My botany colleagues would come in and start asking me if I got tired of rove beetles (never!) and wanted to switch to plant systematics. You see, Smilax L. is a cosmopolitan plant genus. My typical response was “It’s not a plant!”

So here it is: Smilax deineinephyto sp. n. described in the recently published revision of Smilax (pdf here), the myrmecophilous rove beetle genus. The epithet translates in Greek “It’s not a plant”.



Sometimes we go collect in a rainforest and come back with many new species, species that we knew in the field that were new. Or, we visit a natural history museum and look through their unsorted specimens and we immediately know that there is a new species there. Well, this is not one of these stories. The funny (or annoying, disturbing, same old -  depending on who you ask) story is that the species I described as new in this paper had actually been illustrated before.

From Scheerpeltz 1936.

Scheerpeltz in his 1936 paper, compared the species of Smilax pilosa with Smilax cyanea (then in Cordylaspis). Unfortunately, it seems that he did not study the type specimens for these taxa because what he identified as Smilax pilosa was (mostly) Smilax lynchi (Bruch). Also the type species for Smilax cyanea is conspecific with Smilax pilosa, and does not match what he illustrated as Smilax cyanea above. And thus, here is a new species, hidden in a collection for several decades, masqueraded as a previously described species.
