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 st 4 absent; dorsal shield slightly shortened posteriorly, with two pairs of J-setae on opisthonotal surface (J 1 and J 3); soft integument with two pairs of small suboval platelets close to posterior margin of dorsal shield.................................................................................... Dermanyssus americanus Ewing, 1923  

- Metasternal setae st 4 present; dorsal shield not reduced in length, with at least three pairs of J-setae on opisthonotal surface (J 1, J 3 and J 4 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 (J 2 present), and with at least nine pairs of setae on podonotal surface (z 6 present).................................................................................. 4

- Dorsal shield with three pairs of J setae on opisthonotal surface (J 2 absent), and with eight pairs of setae on podonotal surface (z 6 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 (j 1 and s 1 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 (j 1 and s 1 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 j 3 present; anterior end of peritremes reaching mid-level of coxae II; sternal setae st 1 shorter than setae st 2 and st 3 ............................................................. Ornithonyssus pipistrelli Oudemans, 1903  

- Dorsal shield setae j 3 absent; anterior end of peritremes reaching posterior margin of coxae I; sternal setae st 1 at least subequal

to setae st 2 and st 3 .................................................................................... 8 8. Dorsal shield behind J 3 with three pairs of setae (Z 4, Z 5 and Jx).... Ornithonyssus sylviarum ( Canestrini & Fanzago, 1877)  

- Dorsal shield behind J 3 with four pairs of setae (Z 4, Z 5, S 5 and Jx)............................................ 9

9. J setae relatively longer, J 1 with tip reaching the following setae J 2; opisthogastric soft integument densely setose.................................................................................. Ornithonyssus bacoti (Hirst, 1913)  

- J setae relatively shorter, J 1 with tip reaching between J 1 and J 2; opisthogastric soft integument sparsely setose.................................................................................. Ornithonyssus bursa ( Berlese, 1888)
