对近6年（2007-2012年）在《系统与应用螨学》和《动物分类学》两种期刊上报道的螨类新种的类型定位进行了调查，以发现螨类新种的热点。在642篇论文中，包含新种的论文占71%，2007年为148种，2008年为207种，2009年为234种，2010年为208种，2011年为333种，2012年为249种。2007-2012年，系统与应用动物学（Systematic & Applied Acarology）发表的新种约占《Zoological Record》收录新种总数的3%，而动物分类学（Zootaxa）发表的新种约占35%。1379个新种分布不均匀，分布在150个螨科；前15科占总种数的55%，150科中有86科1-3种。最顶端的科是角虫科，仅角虫科就占所有新种的近15%。在地理上，新种来自92个国家，这些国家之间的分布极不均匀。排名前10位的国家占所有新种的62%，而排名第一的中国仅占总数的18%。每个国家的平均新物种数量为15个，超过平均水平的国家不超过五分之一，40%的国家每个国家只有1-3个新物种。各大洲物种数量最多的国家分别是亚洲的中国（248种）、大洋洲的澳大利亚（166种）、南美洲的巴西（76种）、非洲的肯尼亚（51种）、北美的美国（51种）和欧洲的俄罗斯（42种）。南美洲、东南亚和非洲生物多样性丰富的国家急需加大发现和描述新物种的力度。
The type localities of new mite species described in two journals (Systematic & Applied Acarology and Zootaxa) during the last six years (2007–2012) were surveyed to detect hotspots of new mite species discovery. Among the 642 papers examined, 71% of them contain new species, with 148 new species in 2007, 207 in 2008, 234 in 2009, 208 in 2010, 333 in 2011 and 249 in 2012. Systematic & Applied Acarology published about 3% of the total new species indexed by Zoological Record during 2007–2012, whereas Zootaxa published about 35% of the total. The 1379 new species are distributed unevenly among 150 mite families; the top 15 families accounted for 55% of all the species, and 86 of the 150 families have 1–3 species each. The top family is the Eriophyidae, which alone accounted for nearly 15% of the total new species. Geographically, the new species were described from 92 countries and their distribution among these countries is highly uneven. The top 10 countries accounted for 62% of all the new species and the top country, China, alone accounted for 18% of the total. The average number of new species per country is 15 and no more than a fifth of the countries are above the average, and 40% of the countries have only 1–3 new species each. The top country for each continent is China (248 species) for Asia, Australia (166 species) for Oceania, Brazil (76 species) for South America, Kenya (51 species) for Africa, USA (51 species) for North America and Russia (42 species) for Europe. Increased efforts in discovering and describing new species are much needed for biodiversity-rich countries in South America, Southeast Asia and Africa.
