description: 16. Seeversiella brevipennis Gusarov, sp. n. (Figs. 222­234)
Type material. Holotype,, PANAMA: Chiriquí: 5.9 km N Cerro Punta, Par. Nac. Volcán Barú, 8°52'N [the latitude on the label (8°22'0"N) is incorrect] 82°34'0"W, 2150 m, alder forest litter (R.Anderson), 14.vi.1995 (KSEM).
Paratypes: PANAMA: Chiriquí: ,, same data as the holotype (KSEM).
Diagnosis. Seeversiella brevipennis can be distinguished from other species of Seeversiella by having brown or reddish brown body with yellowish brown elytra, abdominal segments 3­4, legs and mouthparts; large eyes (temple length to eye length ratio 1.6­2.0); glossy pronotum with weak isodiametric microsculpture and asperate punctation; elytra as long as pronotum; wings partially reduced; tergum 8 with three pairs of macrosetae; the distinct shape of aedeagus (Figs. 226­233) and spermatheca (Fig. 234).
Seeversiella brevipennis differs from S. scabricollis in having glossy pronotum with asperate punctation; elytra as long as pronotum; apex of median lobe in parameral view constricted basally (Figs. 226­227; 194­196).
Seeversiella brevipennis differs from S. furcativentris in having glossy pronotum with asperate punctation; elytra as long as pronotum; larger median lobe with longer apex (Figs. 226­229; 212­215).
Seeversiella brevipennis differs from S. brunnea in having glossy pronotum with asperate punctation; elytra as long as pronotum; straight apex of median lobe (in lateral view) (Figs. 228­229; 241­242).
Description. Length 2.6­3.0 mm. Body brown or reddish brown, elytra, abdominal segments 3 and 4, legs and mouthparts yellowish brown.
Head surface glossy, with fine isodiametric microsculpture, fine and slightly asperate punctation, distance between punctures equals 2­3 times their diameter. Temple length to eye length ratio 1.6­2.0. Antennal article 2 as long as 3, articles 4­10 transverse (ratio 1.3­ 1.6).
Pronotum slightly transverse, 1.2 times as wide as head, width 0.53­0.56 mm, length 0.47­0.5 mm, width to length ratio 1.1, surface glossy, with fine and weak isodiametric microsculpture; punctation fine and asperate, distance between punctures equal to 1­1.5 times their diameter. Elytra wider and as long (measured from humeral angle) as pronotum (pronotal length to elytral length ratio 1.0), 1.4 times wider than long, glossy, with fine and weak isodiametric microsculpture; with fine and asperate punctation, distance between punctures equal to 1­2 times their diameter. Wings partially reduced.
Abdominal terga glossy, with fine microsculpture consisting of transverse meshes, with fine punctation, distance between punctures equals 3­6 times their diameter on terga 3­5 and 4­7 times on tergum 7. Apical margin of tergum 7 with white palisade fringe. Tergum 8 with three pairs of macrosetae (Figs. 222, 224).
In males posterior angles of tergum 3 projecting as spines up to 2 times as long as tergum 3 (measured medially); tergum 7 in front of posterior margin with medial tubercle; posterior margin of male tergum 8 with emargination delimited by short projections (Fig. 222).
Aedeagus as in Figs. 226­233. Apex of paramere broad, proximal seta approximately as long as the other three setae (Fig. 233).
Spermatheca as in Fig. 234.
Distribution. Known from Cerro Punta, Panama (Fig. 388). In this locality S. brevipennis is sympatric S. scabricollis.
Natural History. Seeversiella brevipennis was collected in forest litter at altitude of 2150 m.
