摘要
从采自新疆博乐县阿拉山口(海拔290 m)室内灰仓鼠伏龙芝亚种 Cricetulus migratorius caesius耳壳内的一批纤恙螨标本鉴定中发现中国新记录亚属——爱柯纤恙螨亚属 Ericotrombidium中的一个新种,定名为博乐纤恙螨 Leptotrombidium (E.) bolei sp.nov.,它与美丽纤恙螨L.(E.)pulchrum(Sosnina,1950)及索氏纤恙螨L.(E.)sokolovi Kudryshova,1984比较近似,但本新种IP及盾板量度除 AM外均较大,PW-SB≥PL,可与前者区别;IP较小,平均787,幅度763—821,DS较少,排列规则:2+8.6.6.4.2=28,可与后者区别。
A new species of Leptatrombidium collected from Xinjiang is described as the follows:Leptctrobidium (Ericotrombidium) bold sp. nov. body orange in colour when aliving and oval shape when engorged. SIF = 7Bs-B-3-2111-0000. fp= B.B.NBB. Scutum trapezoidal, with two kinds of punctae. Sensilla filliform, with 20-24 branches on the distal 2/3 and some very small barbs near its base. SB somewhat before PL. PL>AL>AM. PW-SB≥PL. Eyes 2/2. fDS: 2 + 8.8.6.6.4.2 = 28, fVS = 31, NDV = 60. Leg Ⅰ = 270, Leg Ⅱ = 240, Leg Ⅲ = 277, Ip = 787. T1=64-69, T2=53-62, T3 = 75-80.The new species is closely similar to L. (E.) pulchrum (Sosnina, 1950) and L. (E.) so-kolovi Kudryshova, 1984. But separable from the former by the IP and standard measurements of scutum, and distinguished from the latter by having smaller IP and the regularity of the arrangment of DS. Holotype and 9 paratypes collected off Cricetulus migrants caesius on July 24, 1977, from Bole County (44.9°N, 82.0°E), Xinjiang.All the type specimens are deposited in the Military Medical Research Institute. Xinjiang PLA, China.
