Lindquist, Evert E. & Moraza, María L., 2009, Anystipalpus, Antennoseius and Vitzthumia: a taxonomic and nomenclatural conundrum of genera (Acari: Mesostigmata: Dermanyssina), with description of four species of Anystipalpus, Zootaxa 2243, pp. 1-39 : 11

Key to genus-group taxa of Anystipalpus and Antennoseius

1. Palpus slender, elongated, about half as long as leg I; palptibia two to three times as long as palptarsus ( Fig. 37 ); sternal shield lacking lyrifissures iv1, iv3, and sometimes iv2 ( Fig. 7 ); tibia IV with nine setae (pl -2 absent).............. ...................................................................................................................................................... Anystipalpus Berlese

- Palpus of normal length, at most one-third as long as leg I, with palptibia less than two times as long as palptarsus ( Fig. 53 ); sternal shield lyrifissures iv1-iv3 present; tibia IV with ten setae (pl -2 present)... Antennoseius Berlese ...... ...................................................................................................................................................................................... 2

2. Legs I with pretarsus and a pair of small to well-developed claws ............................. Antennoseius (Vitzthumia) Thor

- Legs I lacking pretarsus and claws ...................................................................... Antennoseius (Antennoseius) Berlese
