Types of M. vietsi in CNM. Taxonomic placement Mamersopsides appears to be most closely related to Mamersides, on the basis of the similar shape of the chelicerae and several other features (, chaetotaxi and shape of palp; suture leading anteriorly from in- sertions of rV-L; insertions of IV-L without condyles; C4 forming a long medial suture with each other). Nymphs and larv^ae of both species are unknown. Genus: Af^mmö^iw Nordenskiöld, 1905 [3 spp.] Typus generis (): Mamersopsis thoracica Nordenskiöld, 1905. Location of : unknown. No material examined for this srudy Definition (adults) Characters of the v^nisitsiellinae as defined above and: • VS complete and DS divided into a latger poste- romedian plate and sevetal anterior and lateral platelets as given in Fig. 63. Species included Mamersopsis thoracica'HoidcnskioXdi, 1905 is based on 4 specimens from the White Nile (backwaters north of Kaka and among water plants north of Gebel). Mamersopsis thoracica and Mamersopsis circumclusa Viets, 1994 were both described from Africa, while the single female of Mamersopsis vi)'idis Viets, 1935 was reported from wet rice fields in Sumatra (Indo- nesia). Inventor)^ (adults) DS/VS. See definition. Eye-region. Anterior eye-lenses in anterolateral edges of ventral shield. Posterior eye-lenses fused to the sepa- rate small platelets forming the anterolateral edges of the dorsal shield. Äd'. A well-developed ridge leads straight anteriorly from the insertions of IV-L.
