With the characters of the P. cinnamopterus Complex, plus: average pronotal length 2.51 mm (n = 13); head, pronotum and elytra usually dark reddish, pronotum not bicolored; antenna reaching or exceeding middle of pronotum when extended posteriorly, antennomere 9 subquadrate; impunctate median line of pronotum at least three puncture diameters wide at narrowest point, usually about four puncture diameters wide; emargination of sixth visible male sternite in ventral view shallow, about 1/6 as deep as wide; apex of median lobe of aedeagus in parameral view broadly and slightly convexly truncate; sides of median lobe in lateral view distinctly toothed near apex.

Etymology: From the Latin adjective praetermissus, meaning "neglected" or "overlooked", in reference to the late discovery of this widespread species which had been generally misidentified as P. cinnamopterus.

 
 

Figure 7.14.1 Platydracus praetermissus Newton, spec. nov., pronotum. 7.14.2 P. praetermissus, apical antennomeres.
7.14.3 P. praetermissus, aedeagus, parameral view. 11.17.1 P. praetermissus, dorsal habitus. 11.17.2 P. praetermissus, aedeagus, lateral view.

 
  Platydracus praetermissus may be distinguished from all other species of the genus in ECAS by the combination of generally dark reddish color (Fig. 11.17.1); black scutellum; variegated abdomen with only sparse gold setae and paired areas of black velvet setae on the first five visible segments (Fig. 7.9.2); antennae with subquadrate antennomere 9 (Fig. 7.14.2); and the complete impunctate medial line of pronotum about 3-4 puncture diameters wide at narrowest (Fig. 7.14.1). It is definitively distinguished from the other members of the P. cinnamopterus Complex, P. cinnamopterus and P. zonatus, by the structure of the aedeagus (Fig. 7.14.3, 11.17.2).  
 

Platydracus praetermissus is widely distributed in the forested areas of eastern United States: from Long Island, New York, west to Nebraska, south to Texas and east to peninsular Florida (Map 21).  Its distribution in ECAS is shown in greater detail in Map 22. The distribution of this species is generally more southern than the other species of the cinnamopterus Complex and is not yet known to include Canada. However, it may occur in the few, relatively mature hardwood forest patches left in southern Ontario.

Adjacent U.S.: MI, IN, OH, PA, NY

In ECAS, P. praetermissus specimens have been collected from April through October, with most (10 of 15 records) found in May or June.

 
 
 
  The four specimens of P. praetermissus from ECAS with collection data were obtained from forest leaf litter (2), in a barrier pitfall trap (1), and sweeping vegetation in a grassy area (1). In its entire range, this species has been collected most often in ground pitfall traps or in forest leaf litter, and rarely associated with decaying logs or in UV light traps at night (twice each). Unlike P. cinnamopterus, this species is not known to occur under bark.  Note that some historical records of P. cinnamopterus in the literature may refer to this species.
