在经过充分研究的欧洲收割者动物群中，Trogulus Latreille 属表现出意想不到的高度神秘多样性。该物种统一的形态阻碍了对其系统学和分类学的专门形态学方法，初步分子研究估计该物种的数量比目前已知的数量多三倍。目前的研究重点是 Trogulus 内一个明确定义的物种组，结合了分子（~1700bp 28S rRNA 和细胞色素 b 基因）、分布、形态测量和形态学数据。使用贝叶斯推理、最大简约性和最大似然性重建关系，随后使用该信息来评估系统可用性的形态特征并识别导致物种形成事件的生物地理过程。 Trogulus coriziformis 物种组已被定义和诊断，包括八个物种。重新定义了三个物种：T. coriziformis C. L. Koch, 1839，指定了新型；T. Aquaticus Simon, 1879 和 T. cristatus Simon, 1879，指定了选型。四个新物种被描述为：T. balearicus, sp.。十一月来自巴利阿里群岛，T. huberi，sp。十一月来自葡萄牙南部，T. prietoi，sp。十一月来自西班牙安达卢西亚和 T.pyrenaicus，sp。十一月来自比利牛斯山脉中部。 Trogulus lusitanicus Giltay, 1931 被用作统称，可能是指目前难以区分的物种组合。 Trogulus salfii De Lerma, 1948 被提议作为 T. coriziformis 的同义词。在 Trogulus 中，分子遗传数据支持 Trogulus coriziformis 物种组的单系和基础位置。该物种在外部形态（大小、触须乳头状、腿部隆起、身体乳头状结构、形态测量数据）、28S 和细胞色素 b 自体变体以及较小程度上的雄性生殖器形态方面存在差异。该物种群仅限于地中海西部地区，其物种具有异域分布。它们目前的分布与中新世和上新世的地质过程相对应，表明这组生物可能对进一步的生物地理学研究具有相当大的价值。
Within the well researched European fauna of harvestmen, the genus Trogulus Latreille exhibits unexpectedly high cryptic diversity. The species’ uniform morphology hinders an exclusively morphological approach to their systematics and taxonomy, and a preliminary molecular study estimated the number of species to be three times higher than currently known. The current study focuses on a clearly defined species-group within Trogulus, combining molecular (~1700 bp 28S rRNA and the cytochrome b gene), distributional, morphometric and morphological data. Relationships are reconstructed using Bayesian inference, maximum parsimony and maximum likelihood and this information is subsequently used to evaluate morphological characters for systematic usability and to identify biogeographical processes leading to speciation events. The Trogulus coriziformis species-group is defined and diagnosed and includes eight species. Three species are redefined: T. coriziformis C. L. Koch, 1839, for which a neotype is designated, and T. aquaticus Simon, 1879 and T. cristatus Simon, 1879 for which lectotypes are designated. Four species are described as new: T. balearicus, sp. nov. from the Balearic Islands, T. huberi, sp. nov. from southern Portugal, T. prietoi, sp. nov. from Andalusia, Spain, and T. pyrenaicus, sp. nov. from the central Pyrenees. Trogulus lusitanicus Giltay, 1931 is used as collective name and probably refers to a composite of species presently difficult to tell apart. Trogulus salfii De Lerma, 1948 is proposed as a synonym for T. coriziformis. Within Trogulus, the molecular genetic data support monophyly and basal placement of the Trogulus coriziformis species-group. The species to differ in external morphology (size, papillation of palps, apophyses of legs, pattern of body papillation, morphometric data), 28S and cytochrome b autapomorphies and to a lesser degree by male genital morphology. The species-group is confined to the western Mediterranean area and its species are allopatrically distributed. Their present distribution corresponds to geological processes in the Miocene and Pliocene indicating that this group of organisms may be of considerable value for further biogeographic studies.
