Morphological variablility in the chigger mite species Neotrombicula sympatrica (Acariformes: Trombiculidae) from Kyrgyzstan

Aberrations (quantitative chaetotactic deviations, i.e. decreasing or increasing of setae numbers and variations in arrangement of setae) and anomalies (qualitative chaetotactic deviations, for example, partial reduction of scutum, shortening of a seta more than 1.5-2 times, merging of setae) were recorded for 13 taxonomically important morphological structures in the chigger mite species Neotrombicula sympatrica Stekolnikov, 2001. 3308 specimens were studied as a total. 17.2% of them had various morphological deviations. The most common types of aberrations were observed in the number and positions of genualae I (94 specimens), AM seta (79 spec.) and sternal setae (77 spec.). The aberrations of sternal and coxal setae were usually interrelated: the sternal seta was "transferred" from the sternal area onto the coxa, or the other way round take place. The specimens having aberrations of sternal setae were twice as numerous as the specimens with aberrations of coxal setae (77 against 35). The specimens with aberrations of dorsal setae and mastitarsala were very rare (2 spec. each). Among anomalies, the presence of nude galeal seta (91 spec.) and scutal anomalies (66 spec.) were prevalent. The most frequently one form of deviation only was observed in one specimen of N. sympatrica. Nevertheless, the specimens simultaneously having several aberrations or anomalies were also found. 17 types of such combinations were observed, that counts 20.6% of all specimens with deviations. Symmetric deviations, namely the presence of two nude galeal setae (31 spec.), presence of 2 genualae on both legs I (4 spec.), presence of 2 AM (2 spec.) and symmetric reduction of scutal angles (1 spec.), sometimes cause troubles in diagnostics. The quarter of variance in N. sympatrica and in the species N. monticola Schluger et Davydov, 1967 formerly studied by the author turned out as almost identical. The specimens with deviations counted 14.5% of all studied specimens in the latter species. However, the structures of variance in these species is different. In N. monticola, the aberrations of humeral setae were dominant (71.6%) (Kharadov, Chirov, 2001), while in N. sympatrica, the aberrations of other structures were prevalent: genualae I (24.8%), AM (20.9%) and sternal setae (20.4%).     

A New Species of Chigger Mite (Acari: Trombiculidae) from Rodents in Southwest China

This paper describes a new species of chigger mite (Acari: Trombiculidae), Gahrliepia cangshanensis n. sp., from rodents in southwest China. The specimens were collected from Yunnan red-backed voles, Eothenomys miletus (Thomas, 1914), and a Chinese white-bellied rat, Niviventer confucianus (Milne-Edwards, 1871) in Yunnan Province. The new species is unique mainly in its number of dorsal setae (n=21), and it has the following features: fT (formula of palpotarsus)=4B (B=branched), fp (formula of palpal seta)=B/N/N/N/B (N=naked), a broad tongue-shaped scutum with an almost straight posterior margin, and 17 PPLs (posterior posterolateral seta) with a length of 36-43 µm. This chigger mite may also infect other rodent hosts and may be distributed in other localities.

A revision of chiggers in the vulgaris group (Trombiculidae: Neotrombicula)

A revision of chigger mites species, being closely related to Neotrombicula vulgaris (Schluger, 1955), is given. 2 new species are described: N. aideriensis sp. n. from Western Kopetdagh and N. macrovulgaris sp. n. from Western Caucasus. N. aideriensis sp. n. differs from all other species of the vulgaris group by presence of single barb on the lateral seta of palpal tibia in most specimens. This species differs also from N. vulgaris by lesser width of scutum, shorter setae of scutum and idiosoma and by longer legs. N. macrovulgaris sp. n. differs from all other species of the vulgaris group by longer legs, more numerous idiosomal setae and by larger scutum. N. vulgaris is recorded for the first time in Bulgaria, Turkmenistan (western Kopet-Dag) and Krasnodar Territory, N. baschkirica Kudryashova, 1998--in Chuvashia, Kirov Province, Komi Republic and Tyumen' Province, N. kharadovi Kudryashova, 1998--in Russia (Altai Territory) and in Karaganda Province (Kazakhstan). The latter species is reported from several new hosts. Variation of morphometric parameters in the vulgaris group are investigated by the methods of multivariate analysis, the pattern of correlations between them is shown. A complex of diagnostic features in the group is revised. Discriminant functions produced by the computer program DIADIS (A. L. Lobanov, ZI RAS) allows to determine confidently representatives of the vulgaris group. Ecogeographical component of intraspecific variability and character variance at the specific level is revealed in vulgaris group. N. macrovulgaris characterized by the largest scutum, numerous setae and long legs was found in the most rigorous, cold and damp climate (alpine zone of western Caucasus). On the other hand, N. kharadovi, which have the most fine scutum and shortest setae, inhabits rather dry and warm Middle Asia and neighbouring territories. The sample of N. vulgaris collected in the steppe part of Stavropol' Territory differed from the material collected in mountain forests of Western Caucasus by low values of the most part of measurements. N. kharadovi samples from plains of Middle Asia differed from samples of this species collected in western Pamirs, central Kazakhstan and Altay Territory by more fine scutum and shorter setae.

Cytology of various antennal setae in a troglobitic Mysidacea (Crustacea)

Summary The various antennal setae can be differentiated from each other by the number and the type of their dendrites and by the cuticular structure of their external parts; these features correspond to functional differences. Moreover, the work revealed differences in relation to the corresponding setae of a marine Mysidacea previously studied by Guse (1978). Various hypotheses linking the ultrastructural differences to those that characterize the environments in which these two species live can be put forward.Abbreviations A1, A3 simple setae A1, A3 - An antenna - B1, B2 setulate setae B1, B2 - Bi bifid seta - bp bending plane - c1, c2, c3 type 1, 2, or 3 cilia (outer dendritic segments) - cu cuticle - d1, d2, d3 type 1, 2, or 3 dendrites (inner dendritic segments) - ec enveloping cell - g Golgi apparatus - h helically arranged cuticle - md microtubule doublet - n nucleus - p apical pore - r ciliary root - s setules - sc scolopale - scc scolopale cell - Si sickle-shaped seta - sm small seta - st stopper - t extracellular matter tube

New species and sympatric relations of the chigger mite species group Talmiensis (Trombiculidae, Neotrombicula)

A revision of chigger mites species being closely related to Neotrombicula talmiensis (Schluger, 1955) has been performed. 2 new species are described: N. pontica sp. n. from Krasnodar Territory (Western Caucasus) and N. sympatrica sp. n. from Krasnodar Territory, Daghestan, Tuva, Armenia, Kirghizia and Turkey (Rize Province). N. pontica sp. n. is closely related to N. carpathica Schluger et Vysotzkaya, 1970 and differs from this species by the larger number of idiosomal setae (NDV = = 75-99 against 63-77), shorter legs (Ip = 782-847 against 844-920, TaIII = 67-74 against 70-80), lesser m-t (0.180 against 0.192), slightly lesser scutum and slightly longer setae. N. sympatrica sp. n. is closely related to N. carpathica and differs from this species by the longer scutal and idiosomal setae (PL = 67-78 against 57-69, H = 65-75 against 57-68, Dmin = 43-52 against 39-48, Dmax = 61-70 against 54-64), longer legs (Ip = 892-973 against 844-920, TaIII = = 77-86 against 70-80) and lesser m-t (0.168 against 0.192). N. carpathica is reported for the first time from Northern Caucasus (Karachai-Cherkess Republic, Kabardino-Balkaria, North Ossetia); N. talmiensis is reported for the first time from Khakasia. Data on joint occurrence of 3 species are reported. The 3 types of sympatric pairs of the species have been found in the Western Caucasus: 1) N. pontica sp. n. and N. sympatrica sp. n., 2) N. sympatrica sp. n., and N. carpathica, 3) N. pontica sp. n., and N. carpathica. Differences between species in that localities, where the joint occurrence was recorded, have been analysed. Sympatric relations between N. sympatrica sp. n. and N. carpathica are characterized by increased value of some general diagnostic characters of these species, such as the length of idiosomal setae and length of legs. Different characters play main distinguishing role in different sympatric localities. Besides that, some local features appear in certain species of sympatric pairs (narrow scutum in 3 samples of N. carpathica, numerous idiosomal setae in 1 sample of N. sympatrica), that differs the populations of the sympatric pair, and also discriminates such aberrant group from other material of the same species. Functions produced by the method of discriminant analysis are proposed for the purpose of diagnostics in talmiensis group. Tests for assumptions of discriminant analysis, such as normality and homogeneity of variances, has been performed beforehand. Verifications of the functions on test samples demonstrated the good quality of its working. Key to species using discriminant functions has been constructed.
