First record of the mite genus Neharpyrhyncuhus (Acari: Harpirhynchidae) in the Russian fauna

The mites of genus Neharpyrhynchus Fain, 1972 (Acari: Harpirhynchidae) are recorded from Rissia for first time. Two species, N. hippolae sp. n. from Hippolais icterina (Passeriformes: Sylviidae) and N. plumaris (Fritsch) from Fringilla coelebs (Passeroformes: Fringillidae) from N. W. Russia was found. N. hippolae sp. n., female holotype (all measurements in mkm, abbreviations--see Fain e.a., 1999): L 517, W 382, LS 179, WS 325, PA 27, thicker than PI 49 and PE 24, pts smooth, vi, ve [symbol: see text] sci are subequal, about 94, l5 247; propodosomal shield not divided; anterior region of pronotum with rounded verrucosites; venter without scales; legs I-II with 2 free segments and strongly developed lobes at their bases; legs III-IV with one segment, bears 4 and 5 setae respectively (in paratypes number of these setae is variable, 4-5). Male: L 227-254, W 210-219, LS 129-134, WS 170-183, pts are smooth, ve 78-87, sci 83-90, sce 89-95, h 90-110; penis 49-56 long; legs III with 2 free segments, basal segment bears seta, apical segment with 5-6 setae; legs IV with one free segment, it bears 4-5 setae. The new species is closely related to N. pilirostris (Berlese et Trouessart, 1889) and distinguished by characters as follows. N. hippolae sp. n. (female): the setae PI about 2 times are longer than PA and PE; the apical segment of legs III-IV bears 4-5 setae. N. pilirostris: setae PA, PI [symbol: see text] PE are subequal; the apical segment of legs III-IV bears 4 setae only. N. plumaris differs from closely related species N. novoplumaris Moss e.a., 1968 by characters as follows. In female of N. plumaris, the setae PA are subequal to PE and 1.6-1.8 times shorter than PI. In N. novoplumaris, the setae PA shorter than PI and PE.     

A description of the female and larva of the relic species Ixodes ghilarovi (Ixodidae)

Ixodes (Exopalpiger) ghilarovi was found in 4 separated localities of the Great Caucasus at a height of 1000 to 2200 m above sea level. Female differs from palaearctic I. (Exopalpiger) trianguliceps in 4-4 pairs of setae of the anal valve, shape of scutum, longer setae of alloscutum, more round peritreme, correlation between the length of peritreme longitudinal diameter and the length of longitudinal diameter of the anal ring, presence of auricles and shape of palps. Larva differs from I. trianguliceps in longer setae of alloscutum, longer ventrolateral tooth of 1st palpal joint and longer medial tooth of coxae I.     

New Quill Mites of the Family Syringophilidae (Acari: Cheyletoidea)

Five new species and two new genera belonging to the family Syringophilidae (Acari: Cheyletoidea) are described from birds that died in the Antwerp Zoo during their quarantine: Charadriaulobia vanelli n. g., n. sp. from Vanellus chilensis (Charadriiformes: Charadriidae) in Brazil; Fritschisyringophilus lonchurae n. g., n. sp. from Lonchura punctulata (Passeriformes: Estrildidae) in India; Mironovia coturnae n. sp. from Coturnix coturnix (Galliformes: Phasianidae) in Europe; Syringophiloidus daberti n. sp. from Passerina ciris (Passeriformes: Emberizidae) in Mexico; and S. serini n. sp. from Serinus mozambicus (Passeriformes: Fringillidae) in Central Africa. Charadriaulobia n. g. differs from the closely related Aulobia Kethley, 1970, in both sexes, by the divergent epimeres I; in females, by the absence of protuberances on the hypostomal apex and by the situation of the bases of setae l4 distinctly anterior the bases of setae d4. Fritschisyringophilus n. g. differs from the closely related Syringophiloidus Kethley, 1972, in both sexes, by the presence of setae vs ' on legs II, the absence of setae dT on legs III and IV; in females, by the presence of median hypostomal protuberances and by short setae l1, l2 and l3. The relationships between the Syringophilidae and their hosts are briefly discussed. A list of all known syringophilid genera and their distribution on bird families is provided.
