Abstract

Key to species of Eriococcus discussed here from South America 1. Cruciform pores absent; dorsal setae extremely sparse, almost absent from abdominal segments V–VIII.. ............................................................................................................................................... E.rhadinothrix - Cruciform pores present; dorsal setae reasonably abundant, with some spinose setae present on at least abdominal segments V and VI......................................................................................................................2 2. Venter with abundant long hair-like setae, each up to 130 µm long ........................ E. longisetosus sp. nov. - Venter with shorter scattered hair-like setae, each up to 90 µm long..........................................................3 3. Dorsal spinose setae forming a distinct longitudinal median band...................... E. christopherus sp. nov. - Dorsal spinose setae not forming a distinct longitudinal median band.......................................................4 4. Dorsal spinose setae frequent, with more than 20 on each posterior 2 abdominal segment; with a band of about 20 cruciform pores present on each side between anterior and posterior spiracles.............................. ....................................................................................................................................... E. maximus sp. nov. - Dorsal spinose setae less frequent, with less than 15 on each posterior 2 abdominal segment; cruciform pore band absent on each side between anterior and posterior spiracles.....................................................5 5. Some microtubular ducts forming groups submedially on dorsum, each group surrounded by macrotubular ducts; anal lobes sclerotised ................................................................................ E. paranaensis sp. nov. - Micro- and macrotubular ducts randomly distributed on dorsum; anal lobes membranous or only lightly sclerotised.....................................................................................................................................................6 6. Posterior coxae with few (10–12) large coxal pores; disc pores each with a narrow sclerotised border; anal lobes membranous .............................................................................................E.. venezuelaensis sp. nov. - Posterior coxae with many (20–38) small coxal pores; disc pores each with a broad sclerotised border; anal lobes generally lightly sclerotised ..........................................................................................
