ABSTRACT. The paper presents descriptions or (our new species of gall mites from Tamil Nadu. They are: Abacarus asiaticae, sp. nov; AClilops befontcae, sp. nov; Erfop/Jycs antiJotalae. sp. nov; and ErlophFes l'r/J""aglrlens/s, sp. nov.

Four new species of eriophyids were collected and studied from Vriddha­chalam area during the course of survey in Tamil Nadu. They are described here. The type-slides have been deposited in the Depar.tment of Agricultural Entomology collections, Tamil Nadu Agricultural University, Coimbatore (TNAU).

2. Aculops bctonicae, sp. nov. (Fig. 2)

Remarks: White in colour, on the lower side of leaves, in sunken' spots at feeding sites, causing light specking on leaf surface.

3. Eriophyes antidotalae, ,sp. nov. (Fig. 3)

This species resembles Eriophyes saccharini (Wang, 1964) and E. zealus Kci· fer, 1978 in its shield pattern bu~ can be differentiated from them by the 5-rayed feather claw, number of scorings on the female genital coverflap and the shape of the female ge,nital cover flap and spermathecal glands, apart from the measurements of the various structures.

Fe?nale : 220-230 I-' long; 4S I-' thick; rostrum 18 I-' long evenly down 9urved, antapIcal seta S p.

Remarks: Mites found under the leaf sheath, cause witches broom in the shoot due to shortening of internodes and growth or. axillary buds.

4. Eriopbycs nlddhagiricnsis, sp. nov. (Fig. 4)

This species resembles Eriophyes llcril (Chanilabasavanna, 1966) and E. rlchensl Keifer, 1971 by its clear shield area and. coxal area but can be differ­entiated from them by the 8·rayed feather claw and the ribbed genital coverflap. Moreoyer, this species is a gall former. In this species two distinct types are found from the same host, the first type forming pin-head sized gaUs on the leaflets while the second type which is distinctly larger int size, forms flower galls on the inflorescence axis the size of which vary from O.S cm to I.S cm in diameter. I renee the descriptions and measurements of both types are given below.

Female: From pin-head sized galls on leaflets; 140·1S0 I' long: SO " thick; worm-like; rostrum IS ,.,. torig, uniformly downcurved, antapical seta 4 I-' long: shield 28 I' wide; 24 " long; shield area clear; sides of shield with few lines in the anterior. cnd; dorsal tubercles at rear shield margin; 18 I' apart; dorsal seta 20 ,.,. long, pointing backward and outward; fore leg 26 I' long; tibia 6 " long; tibial seta ~ I-' long at basal!/l, tarsus S I-' long; claw 7 I-' long, tapering and curved; feather claw g·rayed; hind leg 2S I' long: tibia S I' tong; tarsus 5 " long; claw 7,,, long; abdomen with 5S-58 uniformly microtuberculatc rings; tclosomal tergites smooth without microtuberculation; telosomal sternites with micro­striations; lateral seta 20 I-' long on ring 9; first ventral seta 60 II. long on ring 18;
