Aulonothroscus convergens (Horn)

Throscus convergens Horn 1885: 202

Aulonothroscus convergens , of Horn 1890: 208; Blanchard 1917: 20; Leng 1920: 177; Schenkling 1928: 15; Kirk 1969: 52; Peck and Thomas 1998: 71

Diagnosis. This small (2.4 mm long) species is immediately recognized by the pair of frontal carinae being strong, distant from the eyes, each arcing toward the meson and becoming approximate between the eyes, and then diverging anterolaterally. A ventral incision of each compound eye is broadly triangular and extends approximately to the center of each eye.

Specimens examined. BAHAMAS: Andros Is., Forfar Field Sta., nr Stafford Creek, 22-28-vii-2006, MC Thomas, TRSmith, UV trap in coastal coppice (1, FSCA). The holotype was examined along with high-resolution images ( MCZ Type Database 2014).

Notes. This is the “ Aulonothroscus sp. 1 ” of Turnbow and Thomas (2008). Horn (1885) described A. convergens from Georgia. Blanchard (1917), Leng (1920), and Kirk (1969) listed the species from District of Columbia, Georgia, Florida, Louisiana, North Carolina, New York, South Carolina, and Tennessee. This report of A. convergens from The Bahamas provides a new country record.
