Stina, da je to tako kako ti zamisljas, L brojevi i sp. ne bi ni postojali. Neko bi pogledao usta ribe i rekao koja je vrsta. Tako bas neide.
Ako zelis da proucavas Loricariidae onda kreni da bunaris po net-u mada bi najbolje bilo da vidis da li nesto ima u biblioteci. Vidi sa nekima ko studira biologiju, mora da ima nesto i u vezi toga.
Za pocetak kreni od vrha a to znaci od Loricariidae. Dakle trazi po net-u Loricariidae gosline 1945 , Loricariidae gosline 1947 i to ce da te uputi dalje. Odmah da ti kazem da mnogi tekstovi o tome se ne objavljuju javno na net-u nego se placaju.
Evo ti malo od toga da razmisljas u dobrom pravcu. Dole je taj KEY za Loricariidae od Goslin-a.

3b. Platelets in interopercular region fused, usually bearing hooks and articulating with opercle in such a way that raising of outer opercular border forces interopercular area outward and forward.........................................Ancistrinae
4a. Lower transverse portion of pectoral girdle exposed as a bony bridge across front of chest; caudal peduncle compressed or rounded.. Hypoptopomatinae

covered with small platelets; caudal peduncle strongly depressed.. Loricariinae
5a. Anal rays 1,4; supracleithral plate bordered posteroventrally by the exposed cleithrum; cheeks never with bristles; predorsal plate V-shaped, closely appressed to the dorsal spine, with the prongs of the V extending anteroven-trally; normally three rather symmetrical azygous scutes between supraoccipital and predorsal plate................................................Hypostominae (part)
5b. Anal rays usually 1,5 to 1,6 (possibly 1,4 in Corymbophanes andersoni); supracleithral (supratemporal) plate bordered posteroventrally at least in part by a naked area or by a few to several small platelets.......................................6
6a. Lateral scutes 27-32; predorsal plate minute or absent, never closely attached to the dorsal spine; four or more scutes, exclusive of the predorsal scute, on the midline between supraoccipital and dorsal origin......................................7
6b. Lateral scutes 22-26; cleithrum extending backward over base of pectoral spine.........................Hypostominae (part)
7a. Tooth row of lower jaw not followed by one or more distinct series of enlarged papillae; abdomen without an isolated, regularly six-sided shield of platelets............................. Hypostominae(part)
7b. Tooth row of lower jaw followed by one to several series of distinct, enlarged papillae; abdomen with a rather regular six-sided shield of small, prickly platelets, bordered on all sides by a naked area...................... Neoplecostominae

E sada da bi video da je djavo odneo salu, oblast koja tebe zanima je jos komplikovanija. Loricariidae ima svoju potfamiliju Ancistriae u kojoj se nalaze ti rodovi koje tebe zanimaju. Mislim da znas koliko je to velika potfamilija.
Evo i za njih da ti dam kljuceve pa se onda ti igraj do mile volje u odredjivanju vrsta ali prvo treba da odredis genus (rod) pa tek onda spices (vrstu).
