Male. Dorsal vestiture (
Fig. 3
) with dense, decumbent, appressed brownish scales intermingled with ochreous scales. Dorsum of rostrum with whitish scales, moderately dense. Pronotum with brownish scales, denser. Elytra with minute dark-brown spots. Ventral vestiture and legs with sparse, appressed light-brown scales. Antennae with shiny, blackish-brown pubescence, less dense from scape to segment VII; denser on club. All of segment VIII and apex of VII with dense whitish pubescence. Meso- and metafemora lacking dark vitta.
Rostrum twice as long as wide across base; depressed at apical middle; with median longitudinal carina, narrowed and raised at apex, from apex to middle of frons; dorso-lateral carina lacking. Sides of rostrum finely and densely punctuate (
Fig. 6
). Scrobes careniform at dorsal margin; oval and deep distal pit. Mentum punctate-corrugate. Eyes subrounded, truncated at anterior margin. Convex frons.
Antennae elongated (
Fig. 3
), reaching middle of elytra. Segment
II 1
/3 longer than scape; III 2.5x longer than II, thickened; IV and V subequal in length; VI and VII slightly shorter in length; VIII slightly shorter than VII;
IX 1
/3 shorter than XI; X longer than wide; XI slightly narrowed at apex.
Prothorax slightly longer than wide. Pronotum convex, slightly raised at middle; without depression; surface punctuate-corrugated, elevated interstices. Antebasal carina entire and straight at middle, slightly curved to sides. Lateral carina lacking (
Fig. 4
). Secondary carina entire and smooth. Prosternum subplane, opaque with few coarse punctures. Intercoxal process narrowed. Intercoxal process of mesosternum narrowed, about 1/3 as long as mesocoxae. Metasternum with fine sparse punctures.
Elytra longer than wide across humeri; subparallel sides; basal gibbosities evident, weakly impressed behind the gibbosities; apical declivous with interstriae 3 and 5 slightly swollen; rounded apex.
Abdomen. Ventrites with sparse fine punctures. Ventrites I and II subequal, III–IV slightly shorter. V longer than IV, impressed; subtruncate apical margin.

Etymology.
The specific epithet is a derivative of
Jordan
, and honors Karl
Jordan
, a world expert on anthribids.
Discussion.
Hypselotropis jordani
sp. nov.
is differentiated the short antennae in the male, which reach only the middle of the prothorax and by lacking the pronotal impression.
Hypselotropis jordani
sp. nov.
is distinguished from
H. punctulata
(
Jekel, 1855
)
and also
H. conicollis
(
Jekel, 1855
)
(a clade of sister species) by meso- and metafemora lacking a dark vitta. In particular, the species differs from
H. punctulata
by segment II of antennae 1/3 longer than scape; pronotum convex, slightly raised medially; without any obvious impression; prosternum subplanar, opaque with few coarse punctures; and elytra with subparallel sides and basal gibbosities evident.
