Description.
Body length: 5.2-11.2 mm; stout to elongate, glabrous or setose. Most species are unicolored but some are bicolored (e.g., pronotum and elytra with different coloration).
Head
: Eyes reniform, anteriorly notched by canthus, rarely completely divided. Antennae moderately long, usually reaching or slightly extending past base of pronotum; antennomeres obconical to moniliform.
Thorax
: Pronotum shape variable, quadrate to cordate, usually narrower than width of elytra. Lateral margins complete. Procoxae clearly separated by prosternal process. Mesocoxal cavity laterally closed, at least partially, by mesepimeron. Elytra striate. Metathoracic wings well developed or absent. Legs slender, not fossorial, penultimate tarsomeres lobed or cupuliform.
Abdomen
: Intersegmental membranes visible between sternites V-VII, abdominal hinging tenebrionoid. Defensive glands present (Fig.
65
), gland reservoirs conical, lacking striations, reservoir openings wide. Ovipositor slender, with three to four clearly separated coxite lobes, terminal coxite digitate, gonostyli apical or subapical.
Diagnosis.
Lupropini
can be distinguished from
Goniaderini
and
Prateini
by having the mesocoxal cavity open and abdominal defensive glands present.
In
Lagriinae
, this character combination is shared with
Adeliini
Kirby, 1828,
Pycnocerini
Lacordaire, 1859, and
Lagriini
.
Lupropini
can be distinguished from these tribes as follows:
Both
Adeliini
and
Pycnocerini
possess abdominal defensive glands, but their configuration is different from
Lupropini
.
Adeliini
defensive gland reservoirs open between sternites VIII and IX (Fig.
67
) and
Pycnocerini
possesses just a single rectangular reservoir located medially between sternites VII and VIII (Fig.
66
). In contrast,
Lupropini
has paired reservoirs that open between sternites VII and VIII (Fig.
65
).

Lagriini
also possesses paired defensive gland reservoirs between sternites VII and VIII (Figs
62-64
). This tribe is the most speciose in
Lagriinae
, and is currently divided into three subtribes:
Lagriina
Latreille, 1825,
Statirina
Blanchard, 1825, and
Phobeliina
Ardoin, 1961 (see below for justification of the inclusion of
Phobeliina
in
Lagriini
). The subtribes can be distinguished from
Lupropini
as follows.
Lagriina
is characterized by the terminal antennomere elongate in most species; prosternal process greatly reduced, resulting in the procoxae appearing to be nearly contiguous; pronotum lacks lateral carinae.
Statirina
is characterized by the terminal antennomere elongate in all species; prosternal process narrow or wide, clearly separating procoxae; pronotum has complete lateral carinae.
Phobeliina
is characterized by the terminal antennomere subequal to penultimate antennomere; prosternal process wide, clearly separating procoxae; pronotum lacks lateral carina. In contrast,
Lupropini
has terminal antennomere subequal to penultimate antennomere; prosternal process wide, clearly separating procoxae, pronotum with lateral carinae clearly developed, at least in anterior fourth.
