Seeversiella similis Gusarov , sp. n. ( Figs. 161­174 ) FIGURES 161­164 . Abdominal segment 8 of Seeversiella similis Gusarov , sp. n. (161­162, holotype; 163­164, paratype from La Tigra, Honduras). 161 – male tergum 8; 162 – male sternum 8; 163 – female tergum 8; 164 – female sternum 8. Scale bar 0.2 mm. Type material. Holotype ,, HONDURAS : Francisco Morazán: 21.3 km N Teguicigalpa, La Tigra, 2100 m , 14°12'N 86°06'W , forest litter (R.S.Anderson), 7.vi.1994 ( KSEM ). Paratypes : HONDURAS : Francisco Morazán: 4, same data as the holotype ; 2, ditto but 15.viii.1994 ; 2, 4, ditto but 22.2 km N Teguicigalpa, 2030 m , 15.viii.1994 (all ­ KSEM ). Diagnosis. Seeversiella similis can be distinguished from other species of Seeversiella by having brown body; temples 1.4­1.8 times as long as eyes; glossy pronotum with weak isodiametric microsculpture; elytra as long or slightly shorter than pronotum (elytral length to pronotal length ratio 1.0­0.9); reduced wings; tergum 8 with four pairs of macrosetae; the distinct shape of aedeagus ( Figs. 165­173 ) and spermatheca ( Fig. 174 ). FIGURES 165­168 . Aedeagus of Seeversiella similis Gusarov , sp. n. (holotype). 165 – median lobe, parameral view; 166 – apex of median lobe, parameral view; 167 – median lobe, lateral view; 168 – apex of median lobe, lateral view. Scale bar 0.2 mm (165, 167), 0.1 mm (166, 168). Seeversiella similis differs from closely related S. badia in that apex of median lobe in lateral view lacks clear emargination on parameral side ( Figs. 167­168 ; 156­157). Seeversiella similis can be distinguished from S. globicollis and the other similar species (3, 5­8, 10) with long elytra and weak pronotal microsculpture by the combination of the following characters: distal sclerites of internal sac poorly sclerotized, not dentiform or hook­shaped and have small spicules ( Fig. 173 ); apex of median lobe in lateral view widened subapically and not emarginate on parameral side ( Figs. 167­168 ); spermatheca S­shaped with umbilicus facing laterally ( Fig. 174 ). Description. Length 2.3­2.8 mm , pronotal width 0.48­0.54 mm . Body brown to dark brown with lighter elytra, legs brown to yellowish brown. In all character states S. similis is very similar to S. globicollis , but differs in the shape of the aedeagus and spermatheca as described in the diagnosis. In males posterior angles of tergum 3 projecting as spines, up to 1 time as long as tergum 3 (measured medially), tergum 7 with medial carina along midline, the carina up to 2/3 as long as tergum length. Aedeagus as in Figs. 165­173 . Spermatheca as in Fig. 174 . FIGURES 169­174 . Genitalia of Seeversiella similis Gusarov , sp. n. (171, 173, holotype; 169­170, 172, 174, paratypes from La Tigra, Honduras). 169 – everted internal sac, parameral view; 170 – medial lamellae, parameral view; 171 – apex of left paramere; 172 – everted internal sac, lateral view; 173 – details of internal sac retracted into median lobe, lateral view; 174 – spermatheca. Scale bar 0.2 mm (169, 172­173), 0.1 mm (170­171, 174). CP – copulatory piece; LD – lateral diverticulum of internal sac. Distribution. Known from Honduras ( Fig. 387 ). Natural History. Seeversiella similis was collected in forest litter at altitude of 2000­ 2100 m .
