M I T E S OF T H E GENUS A M B L Y S E I U S (ACARINA : PHYTOSEI IDAE) F R O M

INDIA W I T H D E S C R I P T I O N S OF E I G H T NEW SPECIES

S.K. GUPTA

Zoological Survey o f India, 34-Chittaranjan Avenue,

Calcutta-12, India

The genus Amblyseius, as emplied in the broad sense of Chant (1965), is so far

represented from India by 37 species. Besides these, another 8 new species are being described here. In order to make this paper more useful, a key for the identification

of all the species known f rom India is given. The species which have not been seen by

the author are marked with astericks (*) and in those cases characters in the key are

given f rom literature. Most of the references on Indian Amblyseius are given in Prasad

(1974). Here, under each species, only the original reference and others not given in Prasad are cited. Pritchard and Baker (1962) has been followed for setal nomenclature.

The material dealt with in the present paper was collected by the author. All the types are deposited in the National Collection of the Zoological Survey of India, Calcutta.

1975 Gupta : Mites af the Genus Amblysetus 31

Male--Unknown.

Collection Data--Holotype : Female, Maldah, West Bengal, on Mangifera indica, 3 April 1968, found associated with mango bud mite (Aceria mangiferae Sayed).

Remarks--This species is close to Amblyseius mutual Denmark but differs in the presence of only one pair of metapodal plates, in absence of posterolateral projection of sternal shield, in leg chaetotaxy and in structure of spermatheca. This species also differs from A. lula Pritchard and Baker, an other close species, in the chaetotaxy of dorsal shield.

Measurements of setae--verticals: 27 ~; dorsocentrals: I-II 13 tz each, III-IV 26 Iz each; clunals: 6 ~; prolaterals: 1 31 ~, II 27 f~, I l l 36 EJ-, IV50 ~t; postlaterals: I 19 l.~, II 27 ~z, III 18 fz, IV 27 ~, V 56 ~ (serrate). Sternal shield concave mediolaterally, metasternal plates with setae. Genital shield (Fig. 7) almost as wide as the maximum width of the ventrianal shield. Ventrianal shield 99 ~ long, 72 ~ wide. VL 1 26 ~ long. Spermatheca as in figure 8. Chelicera (Fig. 9) with 2 teeth on the fixed digit and none on the movable digit. Leg chaetotaxy : genu II 6/0, genu III 5/1, genu IV 5/1, tibia II 4/2,

tibia III 4/2, tibia IV 4/2. Macrosetae on leg IV (Fig. 10) : genu 49 ~, tibia 36 ~ and basitarsus 70 ,a. Peritremal shield as in figure 11, peritreme extends anteriorly upto prolateral I.

Male Chaetotaxy of dorasal shield same as in female. Spermatophoral process as illustrated (Fig. 12).

Collection Data--Holotype: Female, Botanical Garden, Howrah, West Bengal, on Alstonia scholaris, 7 October 1967. Paratypes: 1 F, 1 M, data same as for holotype ; 2 F, Hooghly, on an unidentified plant, 15 October 1967.

Remarks--The new species is close to A. hibisci (Chant) but can be separated by narrower preanal region of ventrianal shield, in relative lenghts of postlateral setae III and IV and in structure of spermatheca. This new species is further differentiated from A. delhiensis (Narayanan and Kaur), another close species, by the differences in relative lengths of postlateral setae I and II, in presence of t metasternal plates, in shape of spermatheca and spermatophoral process.

their bases. Sternal shield and metasternal plates as in figure 46. Genital shield as broad as the maximum width of ventrianal shield. Ventrianal shield 110 ~ long, 85 ~ widei VL1 31 ~ long. Primary metapodal plate 16 Ix long, accessory plate 6 ~ long. Fixed digit of chelicera (Fig. 47) multidentate, with pilus dentilis, movable digit dentate. Leg chaetotaxy: genu II 5/1, genu III 5/I, genu IV 5/1 ; leg IV macrosetae (Fig. 48) on genu 45 ~, tibia 31 ~, basitarsus 49 ~; genu I 22 ~., genu II 22 !x, genu III 31 ~..

Male Not Known.

Collection DatamHolotype : Female, Naihati (24 Pgs. Dist.), West Bengal, on Syzygium cumini, 27 March 1967.

Remarks---This specis is related to A. asiaticus (Evans), A. oguroi Ehara, A.japonicus (Ehara) and A. daturae n. sp. But can be easily distinguished by difference in relative lengths of dorsal setae and by shape of ventrianal shield. It can be further separated from A. caribbeanus De Leon by macrosetae of leg IV and by shape of ventrianal shield. This species also differs from A. officinaria n. sp. in relative lengths of postlateral seta V.

ACKNOWLEDGE MENTS

The author is grateful to the Director, Zoological Survey of India, Calcutta for extending the laboratory facilities and to Dr. D.N. Raychaudhuri, Reader in Zoology, Cal- cutta University for many valuable suggestions.

ABSTRACT

Eight new species of Amblyseius, viz. Amblyseius aeeriae, A. coeeineae, A. daturae, A. otfieinaria, A. polyantheae, A. pruni and A. syzygii are described and illustrated in this paper. Besides, other Amblyseius spp. known from India earlier are discussed. A key is also provided for all Indian species.
