Legs. Subcoxa I of males with one row of 4 modificated mac finely ciliate, females with 4 regular chaetae, both with 2 psp; subcoxa II with an anterior row of 9 chaetae, posterior row of 4 chaetae, 1 anterior chaeta and 4 psp; subcoxa III with one row of 7 chaetae and 2 posterior psp ( Figs 19 A ‒C ) . Trochanteral organ with about 30 spine-like chaetae ( Fig. 19D ). Unguis with median and apical teeth the same length, basal teeth smaller. Unguiculus with all lamellae acuminate and smooth, no tooth; ratio unguis: unguiculus = 1: 0.57 ( Fig. 19F ) . Tibiotarsus III distally with inner smooth chaeta 1.38 larger than unguiculus; outer tenent hair capitate, discretely ciliate, and 0.64 smaller than unguis.

Leg I of males ( Fig. 19E ). Femur I with one inner row of 9 spine-like mac finely ciliate and apically rounded, 1 mac finely ciliate and apically acuminate and 1 proximal normal ciliate chaeta. Tibiotarsus I armed with three inner rows with 18 proximal short or elongated baster-shaped chaetae finely ciliate, followed by 4 thicker finely ciliate

chaetae.

Furcula ( Fig. 19G ). Manubrium ventrally with formula 1, 2, 2, 2 (smaller)/4 (subapical), 18 (apical) ciliate chaetae; manubrial plate unclear.

Remarks. In the original description S. mantis was not compared with most species from the Western Palearctic region with similar chaetotaxy. Seira mantis is most similar to S. uwei Barra, 2010 by head mac M 4i, S4 and Pa4 absent, basomedian labial field with chaeta R smaller, Th II with 4 medio-central mac (m1‒ 1i, m2‒ 2i) and 5 mac in PmC group, Th III‒Abd IV with 14, 6, 4, 1 and 12 central mac, respectively; and anterior legs of males with spine-like chaetae (see Tabs 1‒2). However, S. mantis differs from this species by Th II with 6 mac in PmA group (up to 8 in S. uwei ), Abd IV with 14 lateral mac (13 in S. uwei ), Ant IV annulated (normal in S. uwei ), unguiculus without basal tooth (present in S. uwei ), and manubrium ventrally with 18 apical chaetae (16 in S. uwei ). Seira mantis differs also from this species by male legs I with 15 baster-shaped chaetae on tibiotarsus, while S. uwei has 20 spine-like chaetae. Other comparisons among species are presented in Tables 1 and 2.
