在2003年至2012年对老挝的多次考察中，以及2014年对缅甸的一次考察中，在洞穴内外收集了巢蛛科蜘蛛。这是第一次在老挝遇到这个家庭。所有的标本都属于Nesticella Lehtinen & Saintanto，1980。本文描述了4个新种：Nesticella beccus n. sp.（雄性，雌性;老挝：Bolikhamsay Province，琅勃拉邦省，Huaphan Province，坎穆安省，泰国：夜丰颂府省），Nesticella laotica n.（男，女;老挝：万象省，华潘省，琅勃拉邦省，博利坎赛省），Nesticella foelixi n. sp.（male; LAOS：Bolikhamsay Province）和Nesticella michaliki n.（male，female; Myanmar：Chin State）.本文首次描述了柳氏隐翅虫Nesticella yui Wunderlich & Song，1995的雄虫，也是老挝的首次记录。结果从第一个显微计算机断层扫描分析的女性交配器官为这一属。这一分析证明，雌性Nesticella显示出一个复杂的功能receptaculum，这是非常复杂的属内。一种特殊类型的腿刚毛（吸管刚毛）在男性的存在下，建议作为家庭巢的诊断。
During various expeditions to Laos between 2003 and 2012 and one expedition to Myanmar in 2014, spiders of the family Nesticidae were collected inside and outside of caves. This was the first time this family was encountered in Laos. All specimens belong to the genus Nesticella Lehtinen & Saaristo, 1980. Four species have been recognized as being new to science, which are described in this paper: Nesticella beccus n. sp. (male, female; LAOS: Bolikhamsay Province, Luang Prabang Province, Huaphan Province, Khammouan Province, THAILAND: Mae Hong Son Province), Nesticella laotica n. sp. (male, female; LAOS: Vientiane Province, Huaphan Province, Luang Prabang Province, Bolikhamsay Province), Nesticella foelixi n. sp. (male; LAOS: Bolikhamsay Province) and Nesticella michaliki n. sp. (male, female; MYANMAR: Chin State). The male of Nesticella yui Wunderlich & Song, 1995 is described for the first time and it is the first record for Laos. Results from a first micro-computed tomography analysis of a female copulatory organ for this genus are provided. This analysis proves that female Nesticella exhibit a complex functional receptaculum, which is highly complex within the genus. The presence of a special type of leg setae (pipette setae) in males is proposed as diagnostic for the family Nesticidae.
