Mironov, Sergey V., Hernandes, Fabio A. & Pedroso, Luiz Gustavo A., 2015, New feather mites of the genera Aniacarus and Aniibius (Acariformes: Pterolichidae) from two cuckoo species (Cuculiformes: Cuculidae) in Brazil, Zootaxa 3937 (1), pp. 103-126 : 107

Key to species of Aniacarus (Males and females)

1. Prodorsal shield not extending posterior to the level of scapular setae se and si or slightly extending beyond that level between bases of setae si ( Figs. 1 A, 2A). In males, setae ps1 filiform or with filiform apices................................ 2

- Prodorsal shield well developed posterior to the level of scapular setae, postero-lateral angles well expressed ( Figs. 4 A, 5A). In males, setae ps1 of various shapes (spiculiform, lanceolate, or foliform) but without filiform apex...................... 3

2. Prodorsal shield not extending posterior to the level of scapular setae se and si. In males, genital apparatus short and not extending beyond the level of epimerites IIIa, setae e2 filiform, setae f2 and ps2 subequal in length. In females, epigynum as wide as distance between setae 4b............................................ A. mexicanus Gaud and Atyeo, 1990

- Median part of prodorsal shield slightly extending beyond the level of scapular setae between bases of setae si ( Figs. 1 A, 2A). In males, genital apparatus distinctly extending beyond the level of epimerites IIIa; setae e2 narrowly lanceolate, setae ps2 twice as long as setae f2. In females, width of epigynum less than distance between setae 4b................. A. ani sp. n.

3. Setae si and c2 spiculiform. In males, dorsal side of chelicerae with curved row of spines directed backward ( Fig. 12 E), genu I with dorsal longitudinal crest with fine indentations, femur I with two large dorsal spines, setae ps1 dilated, sickle-shaped. In females, hysteronotal gland openings gl situated anterior to setae e2; hysteronotal shield uniformly punctuated, without weakly sclerotized and ornamented area ( Fig. 11 A).................................................. A. coronatus sp. n.

- Setae si and c2 short filiform. In males, chelicerae not modified, without spines, legs I without any crests or spines, setae ps1 straight, narrowly lanceolate or spiculiform. In females, hysteronotal gland openings gl situated at or posterior to level of setae e2; posterior part of hysteronotal shield with weakly sclerotized area having striated ornamentation................... 4

4. In males, setae f2 and ps1 narrowly lanceolate (about 5 µm wide), lateral margins of opisthosoma posterior to setae e2 with small concavities, corolla of adanal suckers with indentations ( Fig. 7 A). In females, setae e1 spiculiform, width of hysteronotal shield 185–210, poorly sclerotized area of hysteronotal shield roughly H-shaped ( Fig. 8 A)............... A. robustus sp. n.

- In males, setae f2 and ps1 spiculiform, lateral margins of opisthosoma posterior to setae e2 without any concavities, corolla of adanal suckers smooth ( Fig. 4 A). In females, setae e1 short filiform, width of hysteronotal shield 155–165, poorly sclerotized area of hysteronotal shield roughly ovate ( Fig. 5 A).............................................. A. simplex sp. n.
