Cephennodes excavatus
species group
This relatively large group of species is characterized by moderately to strongly convex body, often with the head and pronotum darker than the elytra; the aedeagus representing a modified variant of the
latus
form, with large and elongate median lobe, which is suboval in shape and nearly symmetrical or slightly asymmetrical in ventral view, the diaphragm large and exposed (i.e., not concealed by the ventral wall of the median lobe) and approximately perpendicular to the long axis of the aedeagus or oblique, the apical projections subtriangular in shape; and in most species males have modified elytra (with apical or subapical flattenings, projections, impressions or deep excavations often accompanied by modified setae or lateral impressions covered with modified setae) and, less frequently, antennae (enlarged antennomere VII, curved antennomere VI), legs (protibial tooth, projection on the protarsomere V, curved metatibiae) or the last visible abdominal sternite (median mucro). Typically only one of the body parts is modified (most often the elytra), but in some cases multiple modifications occur.
This species group currently comprises 11 species, all occurring in
China
