Taxonomic history

Anisandrus congruens Smith, Beaver & Cognato 2020 (in Smith et al. 2020b): 86.

Diagnosis

2.6–2.8 mm long (mean = 2.7 mm; n = 2); 2.16–2.36 times as long as wide. This species can be distinguished by the mesonotal mycangial tuft the length of the scutellum; elytral disc with a weak to moderate transverse saddle-like depression; posterolateral margin costate to interstriae 5; declivity appearing bisulcate, moderately impressed from striae 1−2, interstriae 3 strongly inflated, tuberculate from summit to apical quarter then becoming flattened and unarmed to apex; and moderate sharp backwardly pointed spine at base of declivital interstriae 2.

This species strongly resembles A. apicalis and A. cristatus and is most easily distinguished by the smaller size, more strongly impressed declivital sulci than A. apicalis and larger spines on interstriae 3 that are sharply pointed but not strongly backwardly hooked.

May be confused with

Anisandrus apicalis, A. cristatus, A. geminatus, A. niger, and A. sinivali.
