目的 无前螨亚科WalchiinaeEwing ,1946与甲逦螨亚科GahrliepiinaeWomersley ,195 2两者孰为符合动物命名法规的优先名 ,争论自 195 2年起经有半个世纪。无前螨亚科的建立是以无前螨属WalchiaEwing ,193 1为模式属在先 ,以后甲逦螨亚科的建立是以甲逦螨属GahrliepiaOudemans ,1912为模式属 ,将无前螨属置于其亚属。现两属均为有效属。作者 ( 1999)对于该两亚科赋予各自新的特征 ,并提升无前螨亚科为科级阶元 ,无前螨科Walchiidae (Ewing ,1946)Wen ,1999。无前螨科的特征为SIF =4B/4Bs/5B/6B N/B 3 /2 2 ( 1) 1( 0 ) 1( 0 ) 0 .0 0 0 0 ,螨体小至大型 ,IP =3 2 0～ 12 2 0。盾板小至大型 ,在背面向后伸展 ,五角形后端尖锐或呈舌形。不具前中毛 (AM或vi)和前中突 (A或N =0 ) ,盾板基本毛式为AL和PL各一对 ,常有附加毛PPLs 2～ 40支不等 ,少数还有间毛 (IM ) 1～ 2对。感器 (Sn或sci)全为短棒杆形。足节式fSP =7.6.6恒定。盾板AM的退化、足节的增多、体触觉毛的减少是沙螨 (恙螨 )的衍征 ,意味无前螨科比沙螨科 (恙螨科 )Trombiculi dae (Ewing ,192 9)和列螨科Leeuwenhoekiidae (Womersley ,1944 )进化 ,三科综合为沙螨总科Trombiculoidea (Ewing ,192 9)necWelbourn ,1991sensuWen ,1999,可使脊椎动物
WalchiinaeEwing, 1946 and Gahrliepiinae Womersley, 195 2, both of which are prioritized names consistent with animal naming conventions, argue for half a century since 1952. The absence of prehistoric subfamily Subfamily was based on WalchiaEwing, 193 1 as the model belongs to the first, after the establishment of subfamily Jia Jia mites is a genus Galliptera genus GahrliepiaOudemans, 1912 as a genus, the genus without mites In its subgenus. Now two are valid genus. The author (1999) Walchiidae (Ewing, 1946) Wen, 1999 for the new sub-families of the two sub-families and the promotion of their non-mite subfamilies to the order of the first order. Anopheriidae is characterized by SIF = 4B / 4Bs / 5B / 6B N / B 3/2 2 (1) 1 (0) 1 (0) 0. 0 0 0 0, mites small to large, IP = 3 2 0 ~ 12 2 0. Shield plate small to large, stretching back in the back, pentagonal sharp or tongue-shaped back. Without AM (or AM) and AM (A or N = 0), the basic hair style of the shield is a pair of AL and PL, and there are usually 2 to 40 PPLs with additional hairs. Hair (IM) 1 ~ 2 pairs. Sensor (Sn or sci) are all short rod bar shape. Foot Festival fSP = 7.6.6 constant. Degradation of shield plates, increased number of foot joints, and reduction of somatosensory hairs are derivatives of the sand mite (Chigger mite), meaning Trombiculi dae (Ewing, 192 9) and Columns The mite Division Leeuwenhoekiidae (Womersley, 1944) evolution, three synthesis of sand mites Trombiculoidea (Ewing, 192 9) necWelbourn, 1991SensuWen, 1999, vertebrates
