description: Genus <i>Allomicythus</i> nov. Ij'Pe <i>species. Allomicythus kamurai</i> sp. nov., by monotypy. <i>Diagnosis.</i> Belonging to the genus group of <i>Echemus</i> Simon, 1878, (= Echeminae) performed by Murphy (2007), the new genus seems to be close to the genera <i>Micythus</i> Thorell, 1897, and <i>Echemus</i> Simon, 1878, known from Southeast Asia, but is separated from these and defined as an independent genus with the following character combination: the anterior eye row procurved, AME and ALE close to each other, posterior eye row strongly procurved, ALE and PLE also closely standing, PME oval and not much modified: the posterior margin of cheliceral fang furrow toothless and without a keel or a sclerotized ridge; labium marginated widely; the anterior lateral spinneret furnished with a large pyriform spigot and some long cylindlical spigots, the median spinneret with five large spigots dorsally; epigynum with a pair oflateral furrow, spermathecae separated in two parts connected by a short tube. <i>Etymology.</i> The generic name is formed by a combination of a Greek prefix allo- meaning 'different from' and the name of the existent genus <i>Micythus</i> derived from Greek proper noun Mikythos. <i>Remark.</i> The arrangement of eyes of this new genus resembles those of some Australian and American genera as <i>Australoechemus</i> and <i>Zimiromus.</i> In the condition of spigots on spinnerets, the new genus allies to those of the African genus <i>Xerophaeus.</i> However, the genus in all should be related to the Asian genera above mentioned. <i>Micythus</i> species from Sabah, Borneo, illustrated in Murphy (2007), especially resembles the type species of the new genus, and may be actually a member of the new genus. According to the illustration of male palp of that undescribed species, some difference in details could be recognized between the Sabah species and the type species of the genus in question, <i>Micythus pictus</i> Thorell, 1897, from Rangoon, Myanmar, which was redescribed by Deeleman­ Reinhold (2001). Although the male of the type <i>species</i> of <i>Allomicythus</i> is unknown, it could be fairly separated from all the known genera by its unique structure of female genitalia. Because gnaphosid spiders of Indochina Region are totally unknown, this record may awake future interest.
