MD-81... Basic strech of the DC-9 into the DC-9-80 or MD-80
MD-82... Basicaly an MD-81 with uprated engines for better perfromance/range
MD-83... Pretty much n MD-82 with even more powerful engines and some extra fuel capacity
MD-87... the socalled "short" version of the MD-80, featuring a shrink of the fuse for thinner routes
MD-88... n MD-80 with better engines, new flt deck, modified cabin and more range
MD-90... a slight strech of the MD-80 featuring a completly new set of engines

Let me clarify a few things. The MD-88 was a program offered for Delta to install a new glass flight deck on its MD-82s. The program was only offered for MD-82s.
It's simply an MD-82 flight deck upgrade.
The MD-90 featured many new improvements. In addition to being stretched and being powered by new, quieter, more powerful, more fuel efficient IAE V2500s, it included the same glass cockpit of the MD-88. The plane was also made with some newer, lighter composite materials. It also had larger fuel capacity for increased range. MD offered the MD-90ER, but as far as I know, no airline ever ordered any.

Probably there is a visua difference between the different MD 80 series.
With the MD 87 production the rear "cone" of the fuselage was sobstituited by a "knife cone". This improvement was made on all the Md 80 production since them.

Several of the MD-80s had the "beaver tail" you are referring to. I've seen many names for it, but "beaver tail" is the only one I've seen from MDD/Boeing. In any event, after 1986, airlines had the option of adding the beaver tail to all but the MD-81. At NJ, our MD-83 and MD-87s all had this feature. All of our MD-82s had the conical tail. However, I've seen AA MD-82s with the "beaver tail" as well.
Outwardly, it is nearly impossible to tell the difference between an MD-81, -82, -83, or -88. The MD-90 is longer, has larger engines, and IIRC it has the high-top tail seen on the MD-87 and 717.
I would also like to clarify for anyone out there with the misconception that the 717 was simply a short MD-90. That is not the case. The 717 went back to the original DC-9-30 and -40 series and completely rebuilt them with the most advanced technology marketably available. The 717 is a completely new aircraft compared to the MD-80 or MD-90.

After MDD introduced glass cockpits on the MD88, many airlines wanted them and had their MD82s and MD83s upgraded to them or delivered from the factory with them. The AA MD82s and MD83s I've been able to see up front had glass cockpits.
