Statira pluripunctata
Horn, 1888
Statira pluripunctata is a of darkling beetle in the Tenebrionidae, specifically within the Lagriinae (formerly treated as the separate family Lagriidae). The Statira comprises 'long-jointed beetles' characterized by elongated antennal segments that differ from the bead-like typical of many other darkling beetles. This species was described by George Henry Horn in 1888 and is known from Mexico. Members of this genus are considered 'aberrant' darkling beetles that do not conform to the typical morphological expectations for the family.

Identification
Statira , including S. pluripunctata, can be distinguished from typical darkling beetles (Tenebrionidae) by their elongated, long-jointed rather than the bead-like () segments seen in most tenebrionids. This antennal structure more closely resembles that of ground beetles (Carabidae), potentially causing confusion. However, Statira species have concealed beneath the (unlike the exposed forward-directed jaws of carabids) and move slowly rather than running rapidly. The specific epithet 'pluripunctata' (many-spotted) suggests a spotted pattern on the , though this requires verification for this particular species.
