03F58796FF92FFE2FC6BFB1E14FFF8F4.taxon	discussion	Remarks: This species was based on a single specimen from Texas without specified collecting method. While its aedeagus is distinctive, the elytral punctation considered by Löbl & Stephan (1993) as diagnostic, is too variable and dissection of aedeagus is required to confirm its species identity. The examined specimens are 1.52 - 1.68 mm long, somewhat smaller than the holotype.	en	Löbl, Ivan, Leschen, Richard A. B., Warner, William B.

03F58796FF94FFE5FC4FFD71167DFA13.taxon	discussion	Remarks: The species is a member of the B. picea group as defined in Löbl & Stephan (1993). Its aedeagal characters suggest relationship with B. borealis Löbl & Stephan, 1993 by having the same peculiar shape of the parameres. The shape of the median lobe is also similar though the apical process is in B. arizonensis narrower in lateral view. The new species may be easily distinguished from B. borealis by the bicolorous body, the long laterobasal striae of the ventrite I, and the shape of the sclerotized pieces of the internal sac. It falls in the key to the North American Baeocera (Löbl & Stephan, 1993) under the couplet 5, to B. elongata Löbl & Stephan, 1993. B. elongata is significantly larger and has the submesocoxal lines nearly parallel with the margin of coxal cavities, and deep striae at the base of the ventrite I.	en	Löbl, Ivan, Leschen, Richard A.

03F58796FF95FFE6FEF5FA0515CEFE45.taxon	discussion	Remarks: The sole available male has the tip of the median lobe broken off and the basal bulb deformed, though the distinguishing characteristics are retained for naming this species. The shape of the median lobe and parameres of this species are similar with those in members of the B. picea group as defined by Löbl & Stephan (1993) while the presence of a flagellum and the internal sac lacking proximal sclerotized structures suggest relationship with members of the B. apicalis group. Notable is the very thin flagellum much narrower than that in its North American congeners. The new species falls in the key to the North American Baeocera under the couplet 12, to B. similaris Löbl & Stephan, 1993. It differs drastically from B. similaris by the elytral and abdominal microsculpture, and by the ventrite I margined by round, not elongate, pits.	en	Löbl, Ivan, Leschen, Richard A.

03F58796FF96FFE6FEE4FDB313C6F952.taxon	discussion	Remarks: This new species is clearly a member of the B. picea group (see Löbl & Stephan, 1993). The median lobe and parameres are similar with those in B. scylla (Cornell, 1967), while the shape of the sclerites of the internal sac are distinctive, and the presence of a proximal subtriangular plate is diagnostic for this new species. Baeocera vintercepta is readily distinguished from B. scylla by the longitudinal striae at the base of the ventrite I. It may be separated also by the comparatively shorter antennomere XI which is in B. scylla nearly twice as long as the antennomere X, the submesocoxal lines being not parabolic and having the submesocoxal areas much shorter. The new species falls in the key to the North American Baeocera (Löbl & Stephan, 1993) under the couplet 5, to B. elongata Löbl & Stephan, 1993, as B. arizonensis. These two species possess very distinctive aedeagi, in addition B. vintercepta may be easily distinguished by the uniformly dark body and the antennomeres XI larger, more than twice as long as wide.	en	Löbl, Ivan, Leschen, Richard A.

03F58796FF96FFE8FC5AF8C51666FE05.taxon	discussion	Remarks: This genus comprises less species in North America that Baeocera, while the opposite is in the Old World. To date, 23 species of Scaphisoma have been reported from the USA (Newton et al., 2001), including S. americanum (Löbl, 1987) originally placed in the subsequently synonymized Caryoscapha (see Leschen & Löbl, 2005). The following four species have been listed from Arizona in Löbl (2018): S. commune Löbl, 1997 based on probably a mislabelled specimen of S. convexum Say, 1825 (see Casey, 1893), S. desertorum Casey, 1893, S. pusillum LeConte, 1860, and S. rufulum LeConte, 1860.	en	Löbl, Ivan, Leschen, Richard A.

03F58796FF98FFE8FEE9FDF11624FC44.taxon	discussion	Remarks: The species is in external characters similar with S. commune Löbl, 1997 [a replacement name for the homonymous S. castaneum (Motschulsky, 1845)]. The puncture pattern of the metaventrite and ventrite I enables reliable identification. In addition, the aedeagi of these species differ drastically: S. commune possesses a long, thin flagellum extruded in repose while S. convexum has a robust rod as illustrated in Leschen et al. (1990). Scaphisoma convexum can be collected in numbers from basidiomycete fungi (Newton, 1984; Leschen et al., 1990).	en	Löbl, Ivan, Leschen, Richard A. B., Warner, William B.

03F58796FF9AFFEAFF1AFCB61696F976.taxon	discussion	Remarks: This species was based on a single specimen (LeConte, 1860: 323). It is a male examined by the senior author in 1987, bearing the following labels: small, round golden-colour label, “ TYPE 6639 ” (red) / “ S. rufulum Lec. Cal. ” (handwritten) and my determination label dated 1987. The aedeagus is illustrated for the first time in the present paper (Fig. 15). It is similar with that of S. impunctatum Reitter, 1879 (see Leschen et al., 1990), suggesting close relationships. It differs from that of S. impunctatum by the apical process of the median lobe less inclined, and the parameres more sinuate in dorsal view and narrowed apically in lateral view. Scaphisoma rufulum may be distinguished from S. impunctatum also by its lighter body and completely or to large part fused mesepimera, as in those of S. carolinae Casey, 1893.	en	Löbl, Ivan, Leschen, Richard A.

03F58796FF9AFFEBFF19F8E21782FC0F.taxon	discussion	Remarks: The aedeagus of S. declivum is rather similar with that of S. carolinae Casey, 1893 and S. rubens Casey, 1893, but the apical process of the median lobe is much wider and comparatively shorter, and the parameres are evenly arcuate in dorsal view. The species may be easily distinguished from S. carolinae by the larger and lighter body and the distinct mesepimera, and from S. rubens by the elytra with basal striae. The aedeagus of S. rubens (Fig. 16) is distinctive in lateral view and illustrated for the first time in the present paper.	en	Löbl, Ivan, Leschen, Richard A. B., Warner, William B.

03F58796FF9BFFEBFEF2FC09153AFB7C.taxon	discussion	Remarks: Two widely distributed species are known from the USA (Newton et al., 2001): T. compressum Zimmermann, 1869 and T. gammaroides LeConte, 1860. They may be distinguished by the punctation of the metaventrite, as given in Casey (1893).	en	Löbl, Ivan, Leschen, Richard A. B., Warner, William B.
