ABSTRACT
A new genus, Bannana, is established for two new species that resemble those of the Dysderoides complex. Two new species are described, Bannanacrassispina sp. n. and Bannanaparvula sp. n. Morphological descriptions and illustrations of both new species are given.

Bannanaparvula sp. n. A, B Male bulb, prolateral and retrolateral views C Distal part of male bulb, dorsal view D, E Female genital area, ventral and dorsal views. Abbreviations: apo = apodeme; dkn = dark brown knobs; esp = ear-shaped protrusion; ffp = filiform, curved projection; nb = narrow branch; pr = posterior receptacle; sls = stick-like sclerite. Scales bar: A, B, C, E = 0.05 mm; D = 0.1 mm.

Figure 6: Bannanaparvula sp. n. A, B Male bulb, prolateral and retrolateral views C Distal part of male bulb, dorsal view D, E Female genital area, ventral and dorsal views. Abbreviations: apo = apodeme; dkn = dark brown knobs; esp = ear-shaped protrusion; ffp = filiform, curved projection; nb = narrow branch; pr = posterior receptacle; sls = stick-like sclerite. Scales bar: A, B, C, E = 0.05 mm; D = 0.1 mm.

Mentions: The new genus is similar to Dysderoides but can be distinguished from the latter by the following combination of characters: 1) lacking macrosetae on legs III and IV; 2) having reticulate cuticle on the sternum and the sides of the carapace (Figs 1F, 3D, 4C, 5D), which is smooth in Dysderoides; 3) with radial furrows between coxae I–II, II–III, III–IV on the sternum, which is absent in Dysderoides; 4) females have large dorsal scutum (Figs 3A, B, 5E, F), which is absent or less than half of dorsum in Dysderoides. The new genus can be easily distinguished from Trilacuna and Himalayana by the reduced eyes (Figs 1F, 3D, 4C, 5D) and the reticulate cuticle on the sides of the carapace. Both Trilacuna and Himalayana have normal eyes and usually granulated or sometimes smooth on the sides of the carapace (Eichenberger 2011; Grismado et al. 2014; Tong and Li 2007, 2013). The new genus also can be distinguished from Trilacuna by the short postepigastric scutum in females (Figs 3G, 5G) and by having a furrow connecting the posterior tracheal spiracles in males (Figs 1G, 4F); can be distinguished from Himalayana by the absence of the acute projection in the prolateral dorsal part of the male bulb (see Grismado et al. 2014: fig. 62D–H) and the straight, stick-like sclerite in female genital area (Figs 2I, 6E).
