Key to the species of Dendroseius (deutonymph and female)

1 Most of dorsal setae of prodorsum and opisthonotum short and equal in length, I4 1/3 distance I4 to I5, Z4 1/2 distance Z4 to Z5, only shoulder setae r5 and caudal setae Z5 longer, female 270–290 µm long ................. D. reticulatus (Sheals, 1956) (Palaearctic)

­ Most of dorsal setae of opisthonotum longer than setae of prodorsum, I4 = 1/2 to 3/4 dis­

tance I4 to I5, Z4 reaches the base of Z5 ......................................................................... 2 2 Only the dorsal setae of the posterior half of opisthonotum longer than the other dorsal setae, I4 about 2x I1, Z5 = 3x I5, prongs of tectum distally serrated ............................... 3

­ All dorsal setae of opisthonotum longer than the other dorsal setae, I4 and I1 about the same length, Z5 = 2x I5, prongs of tectum distally pointed and smooth....................... 4

3 Caudal setae Z5 2x the length of i4, I5 half the length of i4, I1 about 1/3 distance I1 to I2, digitus fixus of chelicerae only with 3 distal teeth, deutonymph 255–295 µm long ...... .............................................. D. congoensis Wiśniewski et Hirschmann, 1992 (Africa)
