本文综述了单雌蛛和雌单雌蛛生殖器的基型蜘蛛呼吸系统的形态学。表皮呼吸结构的同源性进行了讨论，根据证据从腹部肌肉和个体发育。编码了10个形态学特征（13个转换），主要来自肺（或气管）后段，并增加了7个非呼吸特征。新的数据与先前发表的分析相结合，产生了44个终端的82个字符的数据矩阵。通过基底蜘蛛和单蕊蜘蛛的系统发育来追踪气管系统的进化，并提供了新的突触形态。第三腹内突的延长是蜘蛛目的一种突触形态。真正的中央气管是Entelegyelae的一种突触形态（与Austrochilinae汇合），气管气孔的极端后移和狭窄也是如此。Tetrablemmidae、Pholomidae、Diguetidae和Plectreuridae因缺乏气管而联合;这些焦油与Scytodidae、Sicariidae和Drymusidae因第三内突融合而联合。
The morphology of the respiratory system of basal araneomorph spiders, the Haplogynae and of Entelegynae with female haplogyne genitalia, is reviewed. The homology of cuticular respiratory structures is discussed in light of evidence from abdominal muscles and ontogeny. Ten morphological characters (13 transformations) were coded, mainly from the posterior pulmonary (or tracheal) segment, and other 7 non-respiratory characters here added. The new data were combined with those of a previously published analysis, resulting in a data matrix of 82 characters scored for 44 terminals. The evolution of the tracheal system is traced through the phylogeny of basal spiders and the Haplogynae, and new synapomorphies are provided. Elongate 3rd abdominal entapophyses are a synapomorphy of Araneomorphae. True median tracheae are a synapomorphy of Entelegynae (convergently with Austrochilinae), as is the extreme posterior displacement and narrowing of the tracheal spiracle. Tetrablemmidae, Pholcidae, Diguetidae and Plectreuridae are united by the absence of tracheae; and these tars are united with Scytodidae, Sicariidae and Drymusidae by the fusion of 3rd entapophyses.
