Hemiloricaria
Hello
What are the key typical characteristics of the genus Hemiloricaria ?
Where can I find an updated genera identification key to sort out the Loricarinae ?
Thanks for the ones who will take some time to answer this (difficult ?) question.

Hi,
You can find the description of these genera here:
Isbrücker, I. J. H. et al. 2002
Diagnose vierzehn neuer Gattungen der Familie Loricariidae Rafinesque, 1815 (Teleostei, Ostariophysi)
DATZ-Sonderheft Harnischwelse 2, Ulmer Verlag 72 S
The Genus Rineloricaria is split there into the genera Rineloricaria, Hemiloricaria, Leliella and Fonchiichthys. Unfortunatly the descriptions are very short and imo vague and i doubt they will survive a revision of the genus Rineloricaria.

No . The Welsatlas was finished long before the description of the genera Hemiloricaria, Leliella and Fonchiichthys.I am almost certain that the information your after can be found in the new book 'WELS ATLAS 1' by Hans-Georg Evers & Ingo Seidel

I don't have the time right now to translate it, i'll do it later if noone else does, ok? ;)What are the key typical characteristics of the genus Hemiloricaria ?
There isn't one afaik.Where can I find an updated genera identification key to sort out the Loricarinae ?

Took a little longer, i had to finish a report, sorry:
The translation may sound a little odd, i tried to stay as close to the text as possible and my english is far from perfect:
"Hemiloricaria Bleeker, 1862.
Rediagnosis (Isbrücker): Hemiloricaria is distiguished by Rineloricaria; thereof the genus is distinguished as follows.
Hemiloricaira: pubescent males with hypertrophied Odontodes (as described and pictured for Rineloricaria lanceolata by Isbrücker 1973: 68-87, figure 3 and 4), firstly located between interorbital and predorsal region (thin, long and nearly straight)and secondly between the suborbital and the opercular region (closely bundled, long and very thin, slightly convoluted Odontodes and a line of less numerous, convoluted, spike-like Odontodes, that are four time shorter than the other Odontodes in that area) and thirdly are located on the pectorals (numerous upright, convoluted backwards, spike-like Odontodes)
All species are slim with the abdomen comletly covered by plates and usually with a filament like extension of the upper and lower not branched caudal ray.
***a species list follows***
Pubescent Rineloricaria males have hypertrophied Odontodes to be found firstly on the suborbital- and opercular-region (closely bundled, long and very thin, slightly convoluted Odontodes) and secondly on the pectoral (numerous quite small, upright, convoluted backwards and spike-like Odontodes).
A revision of the genus Rineloricaria appears very urgently required to me. The Abdomen of most (***Rineloricaria***) species is not completely covered with plates and the not branched rays of the caudal don't have any filament-like extensions."
So the differences between Rineloricaria and Hemiloricaria according to Isbrücker et al are:
1. Different Odontode pattern in adult males as described.
2. No filamentous extensions of the caudal fin spines in Rineloricaria vs. extensions in Hemiloricaria.
3. Abdomen in most Rineloricaria species not completely covered by plates vs. completely covered in Hemiloricaria.
The genera Leliella and Fonchiichthys belong in this group too, but i have to grab some sleep before i translate that .
