- Body larger, 2.5–3.1 mm long; elytra mostly reddish-brown, maculae if present, black............................................. 2

2 Disk of each elytron brown without contrasting markings; prosternal process without lateral carinae ( Figs. 24 , 28 ). ...................................................................................................................................................................................... 3

- Disk of each elytron brown covered with black spots; prosternal process with lateral carinae ( Figs. 9 , 48 )............... 4

3 Elytral suture reddish brown; elytra very finely punctate; prosternal process with anterior margin arcuate anteriorly ( Fig. 28 ); terminal maxillary palpomere about 3.0 times longer than broad ( Fig. 28 ); female abdominal ventrite V triangular with pointed apex ( Fig. 32 ) ...........................................................................................
