184C9759FFABFFD982F9FB78A7A96C91.taxon	diagnosis	DIAGNOSIS: The male of O. truncata sp. n. can be distinguished from its congeners by the thick and sinuous retrolateral palpal tibial apophysis (Figs 1, 4, 7, 9 - 10, 12), by the dorsal tibial apophysis gradually tapering then abruptly becoming a threadlike filament at its half length (Figs 2 - 4, 11), and by the sigmoid membranous conductor (Fig. 1). The female can be recognized by the elongated V-shaped copulatory ducts (Figs 5 - 6, 13) connected to posteriorly located spermathecae (Figs 6, 13). RELATIONSHIP: Males of this new species resemble those of O. onoi Deeleman- Reinhold, 2001 (RMNH, examined) in having a large, apical conductor and a curved embolus, but differ in having a palpal tibial apophysis of different shape. Females closely resemble those of O. armatissima Thorell, 1897 (MSNG, examined) in having elongated, V-shaped copulatory ducts, but in O. armatissima the epigynal region is Otacilia truncata sp. n., male holotype (1 - 4), female paratype (5 - 6).

184C9759FFAFFFDC82F9FA82A7B26DA0.taxon	diagnosis	DIAGNOSIS: Otacilia bifurcata sp. n. can be easily distinguished from its congeners by the triangular basal spike on the embolus of the male palp (Figs 18 - 20), and by retrolateral and dorsal tibial apophyses being subequal in size (Figs 20 - 22). RELATIONSHIP: Males of this new species resemble those of O. zebra Deeleman- Reinhold, 2001 (RMNH, examined) in having two large tibial apophyses on the male palp, but in O. zebra the retrolateral tibial apophysis is significantly smaller. Both species also differ by their body color pattern.	en	Dankittipakul, Pakawin, Singtripop, Tippawan (2014): New species and new records of the spider genus Otacilia Thorell, 1897 (Araneae, Corinnidae) from Southeast Asia.

184C9759FFA3FFD182F9F9CBA6246DA7.taxon	discussion	REMARKS: Deeleman-Reinhold (2001: 419) provided a description and illustrations of the female paratype. The female of this species is recognized by the absence of anterior membranous bursae, by the thick-walled copulatory ducts, and by the specific shape of the spermathecae (Fig. 33). We present here another unique character found only in the female of this species: a digitiform appendage situated on the anterior surface of each spermatheca (Figs 28, 33 - 34).	en	Dankittipakul, Pakawin, Singtripop, Tippawan (2014): New species and new records of the spider genus Otacilia Thorell, 1897 (Araneae, Corinnidae) from Southeast Asia.

184C9759FFA0FFD082E6F9FCA07D6B00.taxon	discussion	REMARKS: Otacilia kao is a pale species with extremely elongated and slender legs. There is a modest variation between the male holotype and the newly collected spiders examined and treated in the present study. The apex of the retrolateral tibial apophysis is slightly different from that of the male holotype (Figs 35, 37). The new male’s palpal configuration closely resembles that of O. sinifera and O. kao in having a simple, curved embolus and a minute conductor (Figs 35 - 36), but O. sinifera can be distinguished by the apex of the retrolateral tibial apophysis being hook-shaped, in addition to its conspicuous opisthosomal pattern. The shape of the retrolateral tibial apophysis in all three species seems to be somewhat similar, so it is difficult to make a conclusion about the taxonomic value of this character. They can be considered as a rather compact group of closely related species. It is possible that O. kao is a species with strong variability within the species and within its populations. However, the variation found in the new males is well within the known limits of the species and is not sufficient to warrant the status of a new taxon.	en	Dankittipakul, Pakawin, Singtripop, Tippawan (2014): New species and new records of the spider genus Otacilia Thorell, 1897 (Araneae, Corinnidae) from Southeast Asia.
