I was looking on the internet to find out what teledont, mesodnot, amphidont etc meant in coleoptra. What the search result found was this very useful information from our dear friend thanos. It's such a shame that he got so agressive in his conversations. He really knew what he was on about.....
All these are Greek names. 'Prioni'* means 'saw' and 'donti' means 'tooth', so a 'prionodont' male Lucanid has many small teeth across the inner edge of its mandibles.
'Telos' means 'end',so a 'telodont' has well-developed teeth at the edge(and/or close to the edge/end) of its mandibles(and can have also -for example in Prosopocoilus or in Odontolabis- 1 more,smaller pair of teeth close to the base of mandibles) . 'Meso' means 'in the middle', so a 'mesodont' has a well-developed pair of teeth in about the middle of the inner edge/side of its mandibles(e.g. mesodonts of Prosopocoilus),and can have an additional pair of(smaller)teeth close to the base of mandibles(e.g. mesodonts of Odontolabis). 'Amphi' means 'both'...,and so on
.'Amphiodont' Lucanids are the smallest males of a species,and have many very small pairs of teeth across the whole inner edge of mandibles(like a saw). Now,,an 'amphiodont' male Lucanid,of course can be characterised also as 'prionodont'. In 'mesamphiodont' there is a pair of teeth in the middle of the inner edge of the mandibles,which is longer/bigger than all the rest small teeth pairs.
Many Lucanids,for example many Odontolabis species(or also Prosopocoilus),have different male forms and,according to the size,they have different shape of mandibles. The largest males are 'telodonts', the medium ones 'mesodonts',and the smallest 'amphiodonts'. 'Telodonts' have the longest and more impressive mandibles in each species,'mesodonts' shorter ones,while 'amphiodonts' the shortest ones(but wide).
Our member Benjamin (poisonarrow) has a nice example on his site,of Odontolabis sommeri pahangensis,where are shown 3 different males(telodont,mesodont,amphiodont).You can check it here:

Another example that comes on my mind is Prosopocoilus fabricei takakuwai.I have a small 'amphiodont' male in my collection from exchange.The big 80+ 'telodont' males are impressive and quite expensive.
And many other examples of Lucanids.
Also,the terms 'amphiodont','telodont' etc are valid in some Prioninae Cerambycids like the ones in the genuses Acanthophorus or Anthracocentrus..For example the biggest 'telodont' males of Acanthophorus serraticornis from India(+90-95mm) or of Anthracocentrus rugiceps from Pakistan(+80mm) have some well-developed pairs of teeth from the middle and close to the end of mandibles,while the smallest 'amphiodont' ones have many tiny pairs of teeth across the whole inner side of mandibles(the mandibles of the females are of the 'amphiodonte' form).

* PS : The Prioninae Cerambycids are named after the 'saw',too,cause the antennae of many species(Prionus etc) are toothed from the one side,like a saw.
