| abstract | In this paper 8 new species of the genus Tenuipalpus are described. All type specimens are deposited in the Institute of Zoology, Academia Sinica.
Tenuipalpus clematidos, sp. nor. (figs. 1-3)
This species resembles T. dimensus Chaudhri (1971) in the number of dorsocentrals and ventral setae, but differs from the latter in having only 5 pairs of dorsolaterals and in the pattern of dorsal integument.
Holotype ♀, allotype ♂, paratypes 20♀♀ 4♂♂, VIII. 31. 1972, Beijing (Dongyuan), on Clematis neracleifolia,; other series of paratypes 23♀♀ 5♂♂, IX. 23. 1977, Beijing (Mt. Badaling), on Clematis brevicaudata.
Tenuipalpus lineosetus, sp. nov. (figs. 4-6)
It is related to T. dimensus Chaudhri (1971), but differs from the latter by: 1. dorsal setae slender, not lanceolate; 2. dorsal integument striae linear, not reticulated; 3. genu of legs I and II each with 3 setae.
Holotype ♀ and paratypes 6♀♀, IV. 18. 1960, Xinjiang (Qiemo, 38° N, 85° E), on poplar.
Tenuipalpus obvelatus, sp. nov. (figs. 7-9)
Very similar to T. carolinensis Baker (1945), but distinguished from the latter by the following characters: 1. rostral shield with lateral sides flattened; 2. dorsal integument striae reticulated incompletely in the middle of hysterosoma; 3. the second dorsolateral hysterosomals rather broad.
Holotype ♀, paratypes 13♀♀ and 8 nymphs, VIII. 30. 1977, Beijing (Mt. Badaling), on Cyperaceae.
Tenuipalpus spatulatus, sp. nov. (figs. 10-12)
It resembles T. carolinensis Baker (1945) in the second dorsolateral hysterosomals being shorter than other ones and in the number of ventral setae on metapodosoma, but its dorsolateral hysterosomals spoon-like and smooth, except the first, second and fifth ones, besides the pattern of dorsal integument striae obviously different.
Holotype ♀ and paratype ♀, IV. 13. 1974, Guangdong (Hainan Island), on Compositae.
Tenuipalpus aurantiacus, sp. nov. (figs. 13-15)
This species is distinguished from T. carolinensis Baker (1945) by the pattern of dorsal integument striae. Holotype ♀, allotype ♂, paratypes 2♀♀ 1♂ and 4 nymphs, VI. 9. 1972, Beijing (Yuanming Park), on Viola philippica.
Tenuipalpus platycaryae, sp. nov. (figs. 16-18)
It is allied to T. burserae De Leon (1957) and T. sanblasensis De Leon (1957), but this species bears a prominent ridge-like tubercle along anterior margin of propodosoma and its hysterosoma differentiated to form an expansion anterior to coxa III.
Holotype ♀, paratypes 6♀♀, V. 24. 1971, Zhejiang (Hangzhou), on Platycarya strobilacea.
Tenuipalpus qingchengensis, sp. nov. (figs. 19-21)
It is very similar to T. orilloi Rimando (1962), but can be separated from the latter by the following characters: 1. dorsolateral hysterosomals narrow, almost clavate; 2. longitudinal striae indistinct on lateral sides of opisthosoma; 3. the first and second propodosomals rather short and tiny.
Holotype ♀ and paratypes 13♀♀, V. 18. 1979, Sichuan (Mt. Qingcheng, 31°N, 103°B), on Viburnum brachybotryum.
Tenuipalpus filicicola, sp. nov. (figs. 22-25)
Closely related to T. hainanensis Wang (1980), but distinguished from the latter by, in nymph, the dorsocentrals of metapodosoma circular and snbequal in length, and in female, the propodosoma trapezoid, with its anterolateral margin angulate, and the dorsocentrals broadly lanceolate.
Holotype ♀, paratypes 20♀♀ and 5 nymphs, VI. 6. 1979, Sichuan (Mt. Emei), on Cyclosorus sp.. |
