In the trapdoor spider genus Euoplos Rainbow & Pulleine (tribe Euoplini), it was discovered recently that two divergent lineages occur in sympatry in eastern Australia. This challenged the monogeneric classification of the tribe and, in combination with inadequate taxonomic descriptions of some species, precluded comprehensive taxonomic revision. To resolve these issues, we conducted a total‐evidence cladistic analysis on a largely undescribed continental fauna—the first such analysis on a group of Australian Mygalomorphae. We combined multilocus molecular data and/or morphological and behavioural data from all known species from eastern Australia (described and undescribed), plus a subset of Western Australian species, to produce a phylogeny for the tribe. We mapped morphological/behavioural characters onto this to identify clade‐specific diagnostic characters, and applied these data to a generic reclassification of the tribe. We recovered two sympatric lineages in the Euoplini (the “wafer‐door” and “plug‐door/palisade” lineages), and revealed the phylogenetic position of all known eastern Australian species within these. Character mapping revealed morphological and behavioural (burrow architecture) features that allow diagnosis of the lineages and clades within them. We erect a new genus, Cryptoforis gen.n., to represent the wafer‐door lineage, describe the type species, Cryptoforis hughesae sp.n., and transfer two species from Euoplos to Cryptoforis: C. tasmanica (Hickman, 1928) and C. victoriensis (Main, 1995). This study resolves phylogenetic structure within the Euoplini, and characterizes clades within the tribe to facilitate future taxonomic revisions. It also demonstrates that, whereas male morphology is more informative, female morphological characters relating to genitalia and the scopulation/spination of the anterior legs display phylogenetic signal in the Euoplini, highlighting the subtle nature of informative female characters in mygalomorph spiders.

未描述的动物群的全证据分析：解析澳大利亚金活板门蜘蛛的进化和分类（Idiopidae：Arbanitinae：Euoplini）

在活板门蜘蛛属 Euoplos Rainbow & Pulleine (tribe Euoplini) 中，最近发现在澳大利亚东部有两个不同的谱系。这对部落的单属分类提出了挑战，并且与某些物种的分类描述不充分相结合，排除了全面的分类修订。为了解决这些问题，我们对一个基本上未被描述的大陆动物群进行了全证据分类分析——这是对一组澳大利亚 Mygalomorphae 的首次此类分析。我们结合了来自澳大利亚东部所有已知物种（已描述和未描述）的多位点分子数据和/或形态学和行为数据，以及西澳大利亚物种的一个子集，以产生该部落的系统发育。我们将形态学/行为特征映射到此以识别进化枝特异性诊断特征，并将这些数据应用于部落的通用重新分类。我们在 Euoplini 中恢复了两个同域谱系（“wafer-door”和“plug-door/palisade”谱系），并揭示了所有已知的澳大利亚东部物种在其中的系统发育位置。字符映射揭示了允许诊断其中的谱系和进化枝的形态和行为（洞穴架构）特征。我们建立了一个新属 Cryptoforis gen.n. 来代表晶片门谱系，描述了类型物种 Cryptoforis hughesae sp.n.，并将两个物种从 Euoplos 转移到 Cryptoforis：C. tasmanica (Hickman, 1928) 和C. victoriensis（主要，1995 年）。这项研究解决了 Euoplini 内的系统发育结构，并描述部落内的进化枝，以促进未来的分类修订。它还表明，虽然雄性形态学信息量更大，但与生殖器和前腿的内窥镜/脊柱有关的雌性形态学特征在 Euoplini 中显示出系统发育信号，突出了 mygalomorph 蜘蛛中信息丰富的雌性特征的微妙性质。
