Discussion. Pleurochrysis fasciifera and simulator are quite close 
structurally; both have similar facial and antennal dimensions and 
lack a pronotal tooth or carina and whitish basolateral spot on 
T-III. P. simulator can be distinguished from fasciifera by the cylin- 
drical brown male flagellum, male scapal basin with a broad medial 
impunctate stripe, and the presence of a strong transverse facial 
carina in both sexes. This carina in simulator is either single, partic- 
ularly in females, or a rough, elevated, rectangular structure. In 
addition, individuals of simulator tend to be greener than those of 
fasciifera. 
Pleurochrysis sur Kimsey, new species 
Holotype male. Body length 6 mm. Scapal basin narrow, with 
broad zone of fine dense punctures and dense silvery setae along 
ocular margins and subtriangular impunctate and polished medial 
zone; brow protruding with strong transverse carina; malar space 0.6 
MOD long; least interocular distance 0.7 times eye width; suban- 
tennal distance 0.7 MOD long; flagellum somewhat flattened: F-I 
1.4 times as long as wide; F-II 1.1 times; F-III 0.8 times; F-V 0.7 
times as long; pronotum without anterolateral tooth or lateral car- 
ina; metanotum and propodeum evenly rounded; R1 subequal to 
stigmal length; S-II spots round, about as far apart as wide; abdom- 
inal punctures about as large as those on thorax; T-III with large 
prepit row swelling, lateral margin strongly convex, pit row pits 
large and deep. Body greenish blue, becoming purplish dorsally and 
black on middle of metanotum and propodeum, anterior margin of 
T-II and III and in submedial transverse band on T-II; tarsi yellow- 
ish; flagellomeres yellow with brown lateral edges; T-III without 
transparent or whitish lateral rim or basolateral spot.
