Monachus seminulum Suffrian, 1858, p. 344. 



Lexiphanes seminulum (Suffrian, 1858). [Resurrected here from synonymy with 

 Lexiphanes guerini (Perbosc, 1839).] 



Diagnostic description : Color piceous, the tarsi, first three antennal 

 segments, clypeus, and hibial palpi tawny. Shape oval, similar to 

 L. affinis, but with the pronotum slightly less robust. Pronotum dull 

 and rugulose, with sparse, fine, obsolescent punctules and a basal row 

 of punctures in most cases. Elytra with deeply impressed submargi- 

 nal stria tions and distinct punctures. Elytral epipleuron with one 

 row of punctures. Body essentially glabrous and shinning (not 

 metallic). Scutellum triangular, with especially straight edges. 

 Antennae with first segment broader and more than twice as long as 

 second, the third and fourth segments shortest, segments five through 

 eleven broader and more setose. Prosternum and mesosternum 

 rugose. Metasternum finely rugulose and with punctures bearing 

 short setae. First ventral abdominal segment of male rugose between 

 the coxal cavities. Fifth ventral abdominal segment of female with a 

 broad fovea and short setae on either side of it. 



Variation: The observed size range, in millimeters, is 1.58 long by 

 1.17 wide to 2.25 long by 1.50 wide. The average size is 2.00 long by 

 1.33 wide. This species averages smaller than L. affinis, but size 

 ranges overlap so that this distinction is not valid. The general body 

 color in some specimens varies from brownish black to piceous with 

 the slightest hint of deep blue. The last ventral abdominal segment 

 of some specimens is slightly tawny. The appendages vary from 

 light tawny to brown. The distal ends of some of the tibae are also 

 tawny. The elytral punctation is not quite so deeply impressed as in 

 L. affinis and some of the striae become effaced medially.
