Diagnosis.

Trogloneta yunnanense can be distinguished from those Trogloneta species with a pointed abdominal tubercle ( T. cantareira , T. cariacica , and T. mourai in Brescovit and Lopardo 2008: figs 1 A–C, 2A, B, and 2J; and T. speciosum in Figure 2A, B, F, G and T. yuensis in Figure 6A, B, E, F) by the globular abdomen (Figure 9 A–F). It differs from T. canariensis and T. madeirensis (see Wunderlich 1987: figs 375-380, 382-387) by the long embolus, huge cymbial process, a recurved scape, and the unique broad epigynal plate (Figure 10A, B, 11A, B). It differs from the type species T. granulum (see Lopardo and Hormiga 2015: figs 66 A–E, 67A, 128F, 131E) and T. paradoxa (see Gertsch 1960: figs 12, 15, 16) by a well-developed, spoon-shaped cymbial process and a protruded, pentagonal epigynal plate (Figs 10A, C, D, 11A, B). It differs from T. uncata in Figure 5 A–D by the long embolus with a straight, tapering distal end (Figure 10B vs. 5A, C) and a huge cymbial process (Figure 10A vs. 5A, D).

Taxonomic justification.

The type material of Pholcomma yunnanense has been examined as well as its related literatures in this study, the habitus features, the body size, the shape of protruded epigyne with an inflexed space, the broad epigynal plate, the configura tion of vulva with a pair of far apart, globular spermathecae depicted in the type and original illustrations ( Song and Zhu 1994: figs 4 A–C) leave little doubt that the identification is correct. The original illustrations of epigyne and vulva of Pholcomma yunnanense by Song and Zhu (1994) are rather simple and show some differences in comparison with those of Trogloneta denticocleari (Lin & Li, 2008: fig. 17A, D–E), but we have examined the type of Pholcomma yunnanense and the plentiful specimens of Trogloneta denticocleari . Therefore, we consider these subtle differences as being intraspecific variation. To further confirm our judgments using DNA barcoding, a survey at the type locality was specially conducted in August 2018. Unfortunately, the habitat of type locality had become so dry that no samples were obtained. Nevertheless, there are valid reasons to think they are synonyms and T. yunnanense (Song & Zhu, 1994), comb. n. is proposed and transferred from the genus Pholcomma of Theridiidae , as well as T. denticocleari proposed as a new synonym.
