“…nov. with pits, and all other species without pits. This was already stated by Deeleman-Reinhold (1987). She also suggested a geographical separation of these groups, which can no longer be supported, since X. baehrae sp.…”

“…Xyphinus hystrix remained the only known species until 1987, when C.L. Deeleman-Reinhold added six new species to the genus, collected from the Malay Peninsula and Borneo (Deeleman-Reinhold 1987). Her revision of the genus with excellent descriptions and illustrations for the type species and the six new species led to a redefinition of the genus.…”

The goblin spider genus Xyphinus Simon 1893 presents several peculiar characters, such as spines and spikes on carapace and abdomen in different sizes and shapes, strongly modified male palps with distinct apophyses and female epigastric modifications with sclerotized scapi, which can be short or long or even contorted. The genus is restricted to the Old World tropics, except for one species collected also in Australia; as revised here, the group currently comprises 20 species, 10 are newly described: X. holgeri sp. nov., X. deelemanae sp. nov., X. acutus sp. nov., X. sabal sp. nov., X. krabi sp. nov., X. infaustus sp. nov., X. rogerfedereri sp. nov., X. pachara sp. nov., X. baehrae sp. nov., and X. distortus sp. nov. Pseudotriaeris Brignoli 1974 is placed as junior synonym of Xyphinus.

“…The specimens from China have not been compared with the type specimens, and may belong to one or more different species. The generic characters, such as the male palps with complicated apophyses and the male endites with a backwards folded ridge, are very similar to those of the genus Xyphinus Simon, 1893 (see Deeleman-Reinhold 1987 ). We suspect that this genus can be synonymized with Xyphinus .…”

A survey of oonopid spiders in Taiwan with descriptions of three new species

The oonopid spiders of Taiwan are surveyed. Seven genera and 13 species are recognized, including 3 new species: Ischnothyreus kentingensis sp. n., Xyphinus hwangi sp. n. and Xestaspis shoushanensis sp. n. Seven species are newly recorded from this region: Brignolia parumpunctata (Simon, 1893), Opopaea apicalis s (Simon, 1893), Opopaea cornuta Yin & Wang, 1984, Opopaea deserticola Simon, 1891, Orchestina sinensis Xu, 1987, Pseudotriaeris karschi (Bösenberg & Strand, 1906) and Xestaspis loricata (L. Koch, 1873).

“…The unusual genitalia of Molotra, which clearly appear to be derived, suggest a relation among species with similar modifications: a broadly lobed embolar region in the male and a reduced receptaculum in the female. One possibility is Xyphinus Simon, where the male palp does have broad terminal lobes (see figures in Deeleman-Reinhold, 1987) and the female genitalia have recently been shown to lack a receptaculum (Burger, 2010b). However, unpublished images of the Xyphinus palp (made available by Y. Kranz-Baltensperger) show many differences from Molotra, such as a larger number and more complex arrangement of the terminal lobes and an enlarged tibia and patella with prolateral tubercles.…”

The Malagasy Goblin Spiders of the New GenusMolotra(Araneae: Oonopidae)

A new oonopid genus endemic to Madagascar, Molotra, is proposed and its six included species are newly described and illustrated: M. molotra, the type species, M. ninae, M. katarinae, M. suzannae, M. tsingy, and M. milloti. Molotra is defined on the basis of its unusual genitalia. The male has the palpal bulb terminating in broad, liplike lobes, unlike any previously described in Oonopidae. The female is equally unusual in lacking an apparent receptaculum, although the genitalia otherwise resemble those of silhouettelloid genera. The species of Molotra form three distinct groups based on somatic and genitalic characters. The M. molotra group includes four large, strongly spined species. The remaining two are morphologically distinct and known only from males. M. tsingy is a small species with unusual palpi that are complex, contorted, and with a resting position along the sternocoxal boundary, instead of an anterior sternal cavity. M. milloti is a very bristly species that differs somatically from other Molotra but has genitalia similar to the M. molotra group. Molotra is known only from Madagascar where the three species groups are strongly disjunct. The M. molotra group occurs in higher elevation forests (1000-1300 m) in northeastern Madagascar, M. tsingy is from low elevation karst (150 m) of the southwest, whereas M. milloti is from a coastal locality in the northwest.
