Type material. Lectotype of A. globicollis (here designated): CANADA: Ontario:, “Nepigon 0 6.6.18 Ont[ario]. Dr. A.Fenyes”, “248”, “95.” (in red ink), “ globicollis Brh. Cotypus ” (yellow label) ( FMNH); paralectotype: CANADA: Ontario:, “Nepigon 0 6.6.18 Ont[ario]. Dr. A.Fenyes”, “249”, “ globicollis Brh. Typus ” (yellow label) ( FMNH).

Diagnosis. Seeversiella globicollis can be distinguished from other species of Seeversiella by having dark brown body; temples 0.8­2.5 times as long as eyes; glossy pronotum with weak microsculpture; elytra longer than pronotum; wings fully developed, 4 times as long as elytra; tergum 8 with four pairs of macrosetae; the distinct shape of aedeagus ( Figs. 24­31, 33­36 ), especially the hook­shaped distal sclerites of internal sac ( Figs. 31, 35 ); and the shape of spermatheca ( Fig. 32 ).

CP – copulatory piece; DS – distal sclerite of internal sac; LD – lateral diverticulum of internal sac; ML – medial lamellae.

Seeversiella globicollis differs from closely related S. texana in having darker body colour; less distinct microsculpture of head and pronotum; elytra longer than pronotum; fully developed wings, 4 times as long as elytra; straight apex of median lobe (in lateral view) ( Figs. 26­27 ; 43­44); longer copulatory piece of internal sac ( Figs. 29, 34 ; 46, 49­ 50) and spermatheca without umbilicus ( Fig. 32 ).

Seeversiella globicollis differs from the other similar species of Seeversiella (3, 5­8, 10­12) with long elytra and weak pronotal microsculpture in having strongly sclerotized hook­shaped distal sclerites of internal sac and L­shaped spermatheca without umbilicus.

Description. Length 2.4­3.3 mm. Body dark brown, sometimes with lighter elytra and mouthparts.

Head surface glossy, partially with weak isodiametric microsculpture, with fine and weak punctation, distance between punctures equals 2­3 times their diameter. Temples 0.8­2.5 times as long as eyes. Antennal article 2 longer than article 3, article 4 slightly transverse, 5­10 transverse or strongly transverse (ratio 1.5­2.0) ( Fig. 9 ).

Pronotum slightly transverse, 1.2 times as wide as head, width 0.44­0.54 mm, length 0.40­0.47 mm, width to length ratio 1.1, surface glossy, with weak and poorly visible (at 70x) isodiametric microsculpture; punctation as on head. Elytra wider and longer (measured from humeral angle) than pronotum (pronotal length to elytral length ratio 0.9), 1.2 times wider than long, glossy, with fine and weak isodiametric microsculpture, with fine and slightly asperate punctation, distance between punctures equal to 1­2 times their diameter. Wings fully developed, 4 times as long as elytra.

Abdominal terga glossy, with fine microsculpture consisting of strongly transverse meshes, with fine punctation, distance between punctures equals 2­4 times their diameter on terga 3­5 and 4­6 times on tergum 7. Apical margin of tergum 7 with white palisade fringe. Tergum 8 with four pairs of macrosetae ( Figs. 20, 22 ).

In males posterior angles of tergum 3 projecting as spines up to 1 time as long as tergum 3 (measured medially) ( Fig. 17 ), tergum 7 with medial carina along midline, the carina up to 2/3 as long as tergum length ( Fig. 17 ). Posterior margin of male tergum 8 without emargination ( Fig. 20 ).

Aedeagus as in Figs. 24­31, 33­36 . Distal sclerites of internal sac hook­shaped ( Figs. 31, 35 ). Proximal seta of the apex of paramere is much longer than the other three setae ( Fig. 33 ).

Spermatheca as in Fig. 32 , without umbilicus.

Synonyms. The types of A. globicollis agree completely with the detailed description ( Ashe 1986) and with two examined paratypes of S. bispinosa from the type locality, in external characters and in male and female genitalia.

Three specimens in Fenyes collection (CASC) bear a label with the manuscript name “ Sipalia cristata Fenyes ”. Fenyes never published a description of this species.

Distribution. Widespread in North America, from Canada to Honduras ( Figs. 385­ 387 ).

Natural History. Seeversiella globicollis was collected in leaf litter, often near water. In the north of its range S. globicollis occurs at the sea level, in the southern United States and further south the species is restricted to mountainous forests, mostly above 2000 m.
