Two new species, Neotrombicula
jordana n. sp., and Hirsutiella
billabeta n. sp. are described from mice Apodemus
sylvaticus (L.) collected in Navarra Province. Three species
of chigger mites are recorded for the first time on the Iberic
Peninsula: Neotrombicula vulgaris (Schluger, 1955),
Brunehaldia bulgarica
(Vercammen-Grandjean & Kolebinova, 1966), and Cheladonta
pannonica (Kepka, 1956). Data on distribution and morphology
of other 6 species are presented: Neotrombicula autumnalis
(Shaw, 1790), N. japonica (Tanaka, Kaiwa, Teramura
& Kagaya, 1930), N. hispanica Kepka, 1960, Hirsutiella
zachvatkini (Schluger, 1948), Leptotrombidium
europaeum (Daniel & Brelich, 1959), and Schoutedenichia
krampitzi (Willmann, 1955).
Neotrombicula jordana n.
sp. is similar to Neotrombicula solida
Schluger & Davidov, 1967 and N. texana
Schluger, 1962, and differs from the both species in having 3 genualae
I versus 2, nude galeala and dorsal palpal tibial seta versus branched,
smaller scutum (AW=55—63, PW=70—80, SB=20—25, and SD=45—50 versus
AW=74—89, PW=95—109, SB=31—44, and SD=58—69), and shorter legs
(Ip=861—990 versus 1033—1294). N. jordana also
differs from N. texana in having 8 setae in the
first row of D versus 6 and presence of mastitarsala III
Hirsutiella billabeta
n. sp. is similar to Hirsutiella zachvatkini
(Schluger, 1948), and differs from this species in having much more
numerous idiosomal setae (NDV = 226—259 versus 145—180), somewhat
lesser scutum (PW = 84 versus 88, ASB = 38—41 versus 41—48, SD = 53—59
versus 57—66), longer AM (53—83 versus 47—60), and lesser m-t (0.236
versus 0.271). H. billabeta resembles H.
alpina Stekolnikov, 2000 by large NDV, but differs in having
smaller scutum (PW = 81—88 versus 95—108, SD = 53—59 versus 64—69),
shorter legs (Ip = 926—1015 versus 1183—1341, TaIII = 98—105 versus
113—133), and lesser m-t (0.236 versus 0.271).
