Genus Seira Lubbock, 1870 View in CoL

The following characters are shared by both new Seira species and are not repeated in the descriptions:

Scales heavily ciliate, oval or elongated and apically rounded, rarely pointed or irregular, present on Ant I to proximal half of Ant III, head, thorax, abdomen, legs (except empodia), anterior collophore, dorsal and ventral manubrium and dens ventrally ( Figs 1–2 View FIGURE 1 View FIGURE 2 , 3F View FIGURE 3 , 5F–G View FIGURE 5 , 6 View FIGURE 6 , 7E View FIGURE 7 , 10E–F View FIGURE 10 ). Mac heavily ciliate, apically strongly or weakly foot shaped or acuminate. Mic smooth and apically ramificate or simple. Bothriotricha with accessory chaetae ciliated and lanced-shaped ( Fig. 1 View FIGURE 1 ).

Head. Antennae shorter than the trunk length ( Figs 2 View FIGURE 2 , 6 View FIGURE 6 ). Ant IV not annulated, with an apical bulb apically bilobed.Ant I with 3 proximal sens-like smooth chaetae ( Figs 3B View FIGURE 3 , 7B View FIGURE 7 ). Eyes 8+8, G and H smaller, with 5 interocular chaetae (q, s, p, r, t); 2 pairs of bothriotricha (1 subantennal and 1 post-ocellar) present ( Figs 3E View FIGURE 3 , 7E View FIGURE 7 ). Four pointed labral papillae (inner and outer) present ( Figs 3C View FIGURE 3 , 7C View FIGURE 7 ); labral formula with 4 (a1–2), 5 (m0–2), 5 (p0–2) smooth chaetae, a1 not thicker than the others, p0–1 larger than the others ( Fig. 3C View FIGURE 3 ); four prelabral (pl1–2) ciliate chaetae ( Figs 3C View FIGURE 3 , 7D View FIGURE 7 ). Maxillary palp with smooth t.a. and b.c.; sublobal plate with 3 inner subequal appendages and 1 distal minute appendix, all smooth and acuminate. Labial palp with five main papillae (A–E) plus one hypostomal papilla (H), with 0, 5, 0, 4,4, 2 guard appendages, respectively; labial papilla E l.p. pointed and surpassing the papilla apex ( Fig. 3D View FIGURE 3 ). Labium with 5 proximal smooth chaetae ( Fig. 3F View FIGURE 3 ). Basolateral and basomedian labial fields with chaetae a1–5 smooth (a2 larger than the others), M1–2, E, L1–2 ciliated, r reduced to a small smooth spine ( Fig. 3F View FIGURE 3 ).

Thorax and abdomen. Th II not strongly projected over the head, mesothoracic hood absent ( Figs 2 View FIGURE 2 , 6 View FIGURE 6 ); Abd II–IV bothriotrichal formula as 2 (a5, m2), 3 (a5, m2, m5), 3 (T2, T4, D3); Th II–Abd V with ms and sens formula as 1,0|1, 0,1, 0,0 and 1, 1| 0,2, 2,+,3, respectively ( Figs 4 View FIGURE 4 , 8 View FIGURE 8 ).

Legs. Tibiotarsus I–III outer side distally with 1 tenent hair finely ciliate and apically capitate; inner side of tibiotarsus III with 1 distal smooth chaeta ( Fig. 5E View FIGURE 5 ). Pretarsus I–III with one minute smooth chaeta on both sides ( Fig. 5E View FIGURE 5 ). Unguis outer side with a pair of developed lateral teeth (as in Lepidocyrtinus Börner, 1903 ) and one unpaired proximal tooth flattened; inner side with 4 teeth, 2 paired basal (b.t.) and 2 unpaired distally (m.t. and a.t.). Unguiculi with 4 lamellae (ai, ae, pi, pe) ( Fig. 5E View FIGURE 5 ).

Genital plate. Female with two pairs (superior and inferior) of small smooth chaetae, without other modifications. Male’s plate circinate, with 3 unequal eugenital chaetae and about 15 (1 unpaired superior) circumgenital chaetae, all smooth ( Fig. 10H View FIGURE 10 ).

Mucro falcate (distal tooth), without the basal spine; proximal tooth reduced and enveloped by the dens cuticle.
