... the ocular quadrangle is wider than long. Oecobius species differ from Paroecobius by the eyes with approximately the same size, and only the anterior lateral eyes and the posterior median eyes opalescent. The anterior median eyes and the posterior lateral eyes are dark with a black ring on cuticular base (Lamoral 1981;Chamberlin & Ivie 1935: fig. ...

... Female genitalia were cleared in 10% KOH for 24 hours prior to examination. Terminology for the genitalia follows Coddington (1990) and Magalhães & Santos (2018), with introduction of two new terms (AP and LP) and use of the established term conductor (widely used in other spider families) to refer to the membranous area of the palp.

We describe a new species of Oecobius Lucas, 1846 from the Thar Desert ecoregion in India, based on both sexes: Oecobius thar sp. nov.. We also provide photographs of the new species in vivo and the general habitat of its type locality.
... Oecobius Lucas, 1846 is the most diverse genus with 90 species (World Spider Catalog 2023). Some species have broad distribution and are synanthropic (Shear & Benoit 1974, Santos & Gonzaga 2003, 2008, Magalhães & Santos 2018. In Mexico, there are 14 known species of Oecobius (Gertsch & Davis 1937, 1942, Shear 1970, Jiménez & Llinas 2005, Gómez-Moreno et al. 2023, of which O. concinnus Simon, 1893, O. maculatus Simon, 1870, O. navus Blackwall, 1859, and O. putus O.

The oecobiid spider Oecobius juangarcia Shear, 1970 was described more than
fifty years ago based on specimens of both sexes collected from Oaxaca, Mexico.
Since the vulva was neither described nor illustrated in the original description, we
redescribe and illustrate O. juangarcia based on specimens from Chiapas, Mexico.
Furthermore, we provide the first SEM images of the copulatory organs of both
sexes. Additionally, we report new distributional records of O. concinnus Simon,
1893 and O. maculatus Simon, 1870, based on specimens from Chiapas and Coahuila, respectively.
With 90 described species, the genus Oecobius Lucas, 1846 is the largest genus of the family Oecobiidae Blackwall, 1862, five of which are known from China. Since Oceobius przewalskyi was described by Hu & Li in 1987, no males of this species have ever been reported.
The male of Oceobius przewalskyi is described for the first time, based on the specimens collected in Tibet Autonomous Region. Morphological description and illustrations are given.
