description: Key to genera and species of Dermanyssidae and Macronyssidae associated with birds occurring in Slovakia (females)
1. Chelicerae fine and conspicuously elongated, stylet-like, almost subequal in length to legs I; cheliceral digits minute, hardly discernible............................................ Dermanyssus Dugès, 1834 .......................... 2
- Chelicerae at least moderately thick, much shorter than legs I; cheliceral digits well developed, prominent.............. 6
2. Metasternal setae st4 absent; dorsal shield slightly shortened posteriorly, with two pairs of J-setae on opisthonotal surface (J1 and J3); soft integument with two pairs of small suboval platelets close to posterior margin of dorsal shield.................................................................................... Dermanyssus americanus Ewing, 1923
- Metasternal setae st4 present; dorsal shield not reduced in length, with at least three pairs of J-setae on opisthonotal surface (J1, J3 and J4 always present); soft integument never with small scutal elements close to posterior margin of dorsal shield.... 3
3. Dorsal shield with four pairs of J setae on opisthonotal surface (J2 present), and with at least nine pairs of setae on podonotal surface (z6 present).................................................................................. 4
- Dorsal shield with three pairs of J setae on opisthonotal surface (J2 absent), and with eight pairs of setae on podonotal surface (z6 absent or placed on soft integument).................................................................. 5
4. Anterior end of peritremes reaching mid-level of coxae II; dorsal shield with eleven pairs of opisthonotal setae (j1 and s1 present); genu IV with one posterolateral seta.................................... Dermanyssus gallinae (De Geer, 1778)
- Peritremes strongly reduced in length and with anterior end reaching to mid-level of coxae III; dorsal shield with nine pairs of opisthonotal setae (j1 and s1 off the shield); genu IV with two posterolateral setae...................................................................................................... Dermanyssus chelidonis Oudemans, 1939
5. Tibia I, genu I and femur II with two ventral setae; trochanter I without dorsal seta; femur II with one anterolateral seta; humeral platelets fused to or adjacent to anterolateral margins of dorsal shield; idiosomal setae placed on soft caudal integument longer, more robust................................................ Dermanyssus carpathicus Zeman, 1979
- Tibia I, genu I and femur II with three ventral setae; trochanter I with one dorsal seta; femur II with two anterolateral setae; humeral platelets well distant from anterolateral margins of dorsal shield; idiosomal setae placed on soft caudal integument shorter, relatively thin................................................. Dermanyssus hirundinis (Hermann, 1804)
6. Dorsal shield divided, with subequal podonotal and opisthonotal portions.......................................................................... Pellonyssus Clark & Yunker, 1956 ...... Pellonyssus reedi Zumpt & Patterson, 1952
- Dorsal shield undivided, entire.............................................. Ornithonyssus Sambon, 1928 ..... 7
7. Dorsal shield setae j3 present; anterior end of peritremes reaching mid-level of coxae II; sternal setae st1 shorter than setae st2 and st3............................................................. Ornithonyssus pipistrelli Oudemans, 1903
- Dorsal shield setae j3 absent; anterior end of peritremes reaching posterior margin of coxae I; sternal setae st1 at least subequal to setae st2 and st3.................................................................................... 8
8. Dorsal shield behind J3 with three pairs of setae (Z4, Z5 and Jx).... Ornithonyssus sylviarum (Canestrini & Fanzago, 1877)
- Dorsal shield behind J3 with four pairs of setae (Z4, Z5, S5 and Jx)............................................ 9
9. J setae relatively longer, J1 with tip reaching the following setae J2; opisthogastric soft integument densely setose.................................................................................. Ornithonyssus bacoti (Hirst, 1913)
- J setae relatively shorter, J1 with tip reaching between J1 and J2; opisthogastric soft integument sparsely setose.................................................................................. Ornithonyssus bursa (Berlese, 1888)
