Diagnosis

 


   
 
Fore wing with costal cell heavily setose. Submarginal vein (SMV) with 2 setae dorsally. Postmarginal vein (PMV) present and usually slightly longer than stigmal vein (STV).
Antenna with funicle 3- and club 2- segmented in both sexes. Male antenna with sensory pores ventrally on scape and funicular segments constricted apically and setae elongated and whorled.
Head with fronto-facial suture distinctly separated from anterior ocellus, transverse and straight. Occiput with distinct transoccipital ridge. Face with anterior tentorial pits.
Mesosoma quite sculptured. Anterior margin of pronotum with transverse carina. Notauli usually complete, but sometimes difficult to see. Mesoscutum with median groove placed in posterior half. Scutellum with a pair of lateral longitudinal lines, sometimes expressed as row of alveolae, and with a single pair of setae. Propodeum with a median carina and plica. Callus with many hairs.
Petiole distinct.
Coloration usually dark to dark metallic.

 

 
         
     
 
 

Distribution


 

Pleurotroppopsis is a small genus recorded in Australasian, Afrotropics, Holarctic and Oriental regions (Noyes, 2001).

         
 
 

Biology

     

The species of this genus are parasitoids of leafmining Coleoptera, Diptera and Lepidoptera (Noyes, 2001).

       
                                       
 
 

Comments

 
Pleurotroppopsis belongs to the subfamily of Entedoninae by having 2 setae on submarginal vein, scutellum with a pair of setae, fronto-facial suture distinctly separated from anterior ocellus and male scape with sensory pores placed at the ventral edge.
Pleurotroppopsis can be distinguished from Achrysocharoides, Neochrysocharis, Chrysocharis, Asecodes, Trisecodes and Closterocerus by having a transverse carina on pronotum, a longitudinal line placed posteriorly on mesoscutum, a pair of longitudinal lines on scutellum, a single median carina and plica on propodeum. Pediobius (always) and Proacrias (often) have pronotum with transverse carina as well, but they do not have longitudinal grooves on mesoscutum and scutellum and have paired median carinae on the propodeum. Apleurotropis, one of the closest genera to Pleurotroppopsis, can be recognised by not having longitudinal lines on scutellum and by having 2 setae on callus; other characters useful to distinguish them are discussed by Kamijo (1990b). Finally, Kratoysma Boucek, Platocharis Kerrich and Zaommomentedon Girault, other related genera recorded on Lepidoptera leafminers, may be distinguished from Pleurotroppopsis as follows: Zaommomentedon has mesoscutum and scutellum with complete and distinct median groove, Platocharis has diverging submedian carinae or plicae and transverse carina between submedian carina and plica and Kratoysma has scutellum strongly sculptured with broad median groove anteriorly (Schauff et al., 1998).
