Diagnosis.
Larva. Palptarsus with five-branched setae and solenidion (ω) ( Figure 2 View Figure 2 (a,b)); odontus tetrafurcate ( Figure 2 View Figure 2 (a)); cheliceral blade with tricuspid cap and the dorsal side with row of teeth ( Figure 2 View Figure 2 (a)); eyes present, 2/2 ( Figure 3 View Figure 3 ); tracheae and stigma absent; prodorsal sclerite with nasus ( Figures 3 View Figure 3 , 10 View Figure 10 (a)); pair of flagelliform trichobothria (si) ( Figure 3 View Figure 3 ); se setae on prodorsal sclerite ( Figures 3 View Figure 3 , 10 View Figure 10 (a)); Fe legs I–III each entire ( Figure 5 View Figure 5 ); Cx I bisetose ( Figure 5 View Figure 5 (a)); Cx II and III each unisetose ( Figure 5 View Figure 5 (b,c)); pretarsus legs I–III each with claws and claw-like empodium without onychotriches ( Figure 5 View Figure 5 ); Ge I with two solenidia (σ) ( Figure 5 View Figure 5 (a)); Ge II with one solenidion (σ) ( Figure 5 View Figure 5 (b)); Ge III without solenidia ( Figure 5 View Figure 5 (c)); Ta I and II each with subterminal eupathidium (ζ) ( Figure 5 View Figure 5 (a,b)). Deutonymph and adult are unknown.
Etymology. The new genus is named in honour of the epic poem ‘Caramuru’ that exalts Brazilian lands, combined with the word ‘acarus’, which means ‘mite’ in Latin. Gender masculine.
Differential diagnosis. Caramuruacarus Bassini-Silva and Jacinavicius gen. nov. is similar to Akodonacarus Goff and Webb, 1989 , Hannemania Oudemans, 1911 , Leeuwenhoekia Oudemans, 1911 , Mastalacarus Goff and Lukoschus, 1983 , Morelacarus VercammenGrandjean, 1973 and Xenodontacarus Loomis and Goff, 1973 in having five-branched setae on the palptarsus. The new genus differs from Akodonacarus , Hannemania , Leeuwenhoekia , Morelacarus and Xenodontacarus by having only one side of the cheliceral blade with a row of teeth ( Figure 1 View Figure 1 (a)), and four-pronged odontus ( Figure 2 View Figure 2 (a)), while the other genera mentioned above differ by having dorsal and ventral rows of teeth and two or three prongs on the odontus. Furthermore, Caramuruacarus Bassini-Silva and Jacinavicius gen. nov. differs from Akodonacarus by the absence of dorsal eupathidium on Ta I and σ on Ge III – Figure 5 View Figure 5 (a,b) (vs present); from Hannemania by having two σ on Ge I – Figure 5 View Figure 5 (a) (vs multiples) and absence of σ on Ge III – Figure 5 View Figure 5 (c) (vs multiples); from Leeuwenhoekia by the absence of the ζ on the palptarsus – Figure 2 View Figure 2 (b) (vs present); from Mastalacarus by having two σ on Ge I – Figure 5 View Figure 5 (a) (vs one σ), and the absence of σ on Ge III – Figure 5 View Figure 5 (c) (vs present); from Morelacarus by having two σ on Ge I – Figure 5 View Figure 5 (a) (vs one σ), and the presence of σ on Ge II – Figure 5 View Figure 5 (b) (vs absent); and from Xenodontacarus by having the σ on Ge II – Figure 4 View Figure 4 (b) (vs absent) and claws and claw-like empodium without onychotriches – Figure 5 View Figure 5 (vs with onychotriches).
