Champion, 1889
Statira nigromaculata is a of darkling beetle in the Tenebrionidae, originally described by Champion in 1889. It belongs to the Lagriinae, a group formerly treated as the separate family Lagriidae. The Statira is characterized by elongated bodies and relatively long compared to other darkling beetles. This species is part of a diverse tropical fauna with limited published ecological information.

Identification
Distinguished from ground beetles (Carabidae) by bead-like rather than filamentous segments and concealed rather than exposed . Within Tenebrionidae, Lagriinae members like Statira have more elongate bodies and longer antennae than the compact, slow-moving Eleodes-type darkling beetles. The specific epithet 'nigromaculata' refers to dark spotting, but confirmation requires examination of or original description.

Taxonomic History
Statira nigromaculata was described by George Champion in 1889. The Statira belongs to Lagriinae, which was formerly treated as the separate Lagriidae before being subsumed into Tenebrionidae. This taxonomic reclassification explains why some older literature may refer to 'long-jointed beetles' as a distinct family.
Subfamily Characteristics
Lagriinae (long-jointed beetles) differ from other Tenebrionidae in their more elongate, parallel-sided bodies and relatively long, slender . They lack the robust, compact form and seen in many desert-dwelling Tenebrioninae.
