Abstract

Thailand is today the richest country for the genus Troglopedetes Joseph, 1872, with 17 species described from the country. In this study three troglomorphic new species are described from caves in the western region. They are T. spectabilissp. nov. and T. rungsimaesp. nov. from Kanchanaburi province and T. takensissp. nov., from Tak province. The three new species share elongated antennae and have the same number of central mac on Th. III and Abd. IV. However, they differ from one another by the combination of: presence of eyes, antennal length, claw morphology, central head macrochaetotaxy and internal row of dental spines. Troglopedetes spectabilissp. nov. is remarkably different from its congeners by its extreme long appendages, especially the antennae (ratio antenna: head = 5.5). In the second part of the paper the arrangment of antennal chaetotaxy and the diversity of its phaneres is analyzed in the three new species, homologized and compared with those of two other species described from Thailand (T. meridionalis and T. kae). A total of 22 types of chaetae have now been recognized among the species. A new type of S-chaetae for the genus was discovered in this study. There are 5 types of ordinary chaetae, 15 types of S-chaetae, the subapical organite of Ant. IV and scales. A total of 1,107 to 2,183 antennal chaetae on each side were observed, which includes 308–485 S-chaetae, 687–1,402 ordinary chaetae, 72–295 scales and a subapical organite.

文章题目泰国穴居穴居人猿三新种(弹尾目，巨蜥科，穴居人猿科)，并附泰国种检索表

1872年，泰国是目前Trogloopetes属植物最丰富的国家，该国有17种。在本研究中，从西部地区的洞穴中描述了三个穴居形态的新种。它们是壮观T.spectabilisp。nov.和T.rungsimaes。11月，来自Kanchanaburi省和T.takensissp。11月，来自德省。这三个新物种共用细长的触角，在Th.III和Abd上有相同数量的中央mac。IV、然而，它们的不同之处在于：眼睛的存在、触角的长度、爪的形态、中央头部大血管畸形和内排牙棘。眼镜蜈蚣。nov.与同类有着显著的不同，它有着超长的附肢，尤其是触角（触角：头=5.5）。本文第二部分分析了这三个新种的触角毛状体的排列及其显象的多样性，并与泰国的另外两个新种（T.meridionalis和T.kae）进行了同源性比较。目前，该物种共有22种毛科植物。在本研究中发现了一个属于该属的一个新的S-毛科。蚂蚁的近尖有机物，普通毛瓣有5种，S毛瓣有15种。IV和量表。每侧共观察到1107至2183个触角毛，其中包括308–485个S-毛，687–1402个普通毛，72–295个鳞片和一个近尖有机物。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
