摘要
记述伪足瘿螨亚科的1新属:新分位瘿螨属Neodisellagen.nov.,及3新种:菝葜新分位瘿螨Neodisellasmilacaceaesp.nov.,楝叶吴茱萸分位瘿螨Disellameliifoliaesp.nov.,须花藤分位瘿螨Disellalaurifoliussp.nov.。
The present paper deals with a new genus and three new species of Nothopodinae from south China. All measurements are given in p.m. These species were collected from Jinzhong mountain, Longlin County, Guangxi Zhuangzu Autonomous Region. The type specimens are deposited in the Agricultural College, Guangxi University.
Neodisella, gen. nov.
Boby fusiform, anterior lobe present. Dorsal tuber set ahead of rear shield margin, setae directed upward and backward. Coxae with a sternal line; coxae area with granules, first setiferous coxal tubercle absent; tibial setae absent, claw ending as knob; empodium simple. Female genitalia coverflap with granules. 2nd ventral setae（e） absent, with accessory seta.
Type species： Neodisella smilacaceae sp. nov.
Remarks： This new genus is near Disella Newkirk et Keifer（1975）, but can be distinguished from the latter by： 2nd ventral setae（e） absent.

Dorsal shield 37.0 long, 70.0 wide, anterior lobe present; median line incomplete, present only on posterior 314 part of shield, admedian and submedian lines complete, forming network by transverse lines. Dorsal tubercles and setae present. Coxae with granules, first coxal setae absent. Leg Ⅰ 19.5 long, tibial setae absent, claw ending as knob; empodium simple, 4-rayed. LegⅡ 19.0 long. Dorsum with median ridges. Dorsal annuli and ventral annuli with elongate microtubercles. Lateral setae, 1st ventral setae （d） and 3rd ventral setae （f） present, 2nd ventral setae （e） absent. Female genitalia coverflap with granules.
Holotype：♀, Paratypes： 7♀♀3♂♂, Longlin County, Guangxi Zhuangzu Autonomous Region, 01-Ⅻ-2004, collected by WEI Sui-gai, WANG Guo-quan and LI De-wei.
Host： Smilax sp, （Smilacaceae）. Vagrant.
2. Disella meliifoliae, sp. nov. （Figs. 7～11）
Female： Boby fusiform, cream colored, length 140.0～191.0, width 64.0～71.0, thickness 62.5. Rostrum 21.0 long, pointing downwards. Dorsal shield 40.0 long, 65.0 wide, anterior lobe present; median and admedian lines complete, forming 2 line cabins with 3 transverse lines, submedian lines incomplete, front of shield with 2 arc lines and sides of shield with short lines. Dorsal tubercles and setae present. Anterior coxae with granules, first coxal setae absent. Leg Ⅰ 19.5 long, tibia fused with tarsus, claw ending as knob; empodium simple, 3-rayed. Leg Ⅱ20.0 long, tibia fused with tarsus. Thanosome with short middorsal ridges and lateral groove. Annuli subequal dorso-ventrally, both with round microtubercles. Lateral setae and 3 pairs of ventral setae present, Female genitalia coverflap smooth.
This new species resembles Disella octcella Huang 2001, but can be distinguished from the latter by： ront of shield with 2 arc lines; empodium 3-rayed; female genitalia coverflap smooth; anterior coxae with granules and without accessory seta.
Holotype：♀, Paratypes： 14 ♀♀, Longlin County, Guangxi Zhuangzu Autonomous Region, 01-Ⅻ-2004, collected by WEI Sui-gai, WANG Guo-quan and LI De-wei.
Host： Evodia meliifolia Benth （Rutaceae）. Vagrant.
3. Disella laurifolius, sp. nov. （Figs. 12～16）
Female： Boby fusiform, cream colored, length 147.5～210.0, width 59.0～70.0, thickness 56.0～66.0. Rostrum 20.0 long, pointing downwards. Dorsal shield 42.5 long, 66.0 wide, anterior lobe present; median, admedian and submedian lines complete, forming network with transverse lines. Dorsal tubercles and setae present. Anterior coxae with granules, first coxal setae absent. Leg Ⅰ 21.0 long, tibia fused with tarsus, claw ending as knob; empodium simple, 4-rayed.Leg Ⅱ 22.0 long, tibia fused with tarsus.Annuli subequal dorso-ventrally, dorsal annuli smooth, ventral annuli with elongate microtubercles. Lateral setae and 3 pairs of ventral setae present Base of female genitalia coverflap with granules, about 33 longitudinal ribs at apex.
This new species resembles Disella ilicis Keifer 1965, but can be distinguished from the latter by： submedian lines complete; empodium 4-rayed; anterior coxae with granules and without accessory seta.
Holotype： ♀, Paratypes： 7♀♀ , Longlin County, Guangxi Zhuangzu Autonomous Region, 01-Ⅻ-2004, collected by WEI Sui-gai, WANG Guo-quan and LI De-wei.
Host： Genianthus laurifolius （Roxb） Hook. f （Asclepiadaceae）. Vagrant.
