 Fig. 12 



Etymology. — Latin inexpectatus, "unexpected." 



Diagnosis. — A species of the uncifer group closest to T. uncifer Barr, 

 differing in larger size, more convex elytral disc with very shallow striae, 

 and aedeagal apex less produced. 



Description. — Length 3.46-3.59 mm (N = 2). Dark castaneous; legs, 

 mouthparts, and basal antennal segments paler but not flavous as in 

 uncifer, consequently less contrasting. Eye diameter less than scape 

 length. Pronotum closely similar to that of uncifer: sides convergent, 

 then almost subparallel but very briefly so, just opposite posterior mar-
