Eurythrips modestus (Bagnall) comb. n. 

 Malacothrips modestus Bagnall, 191 7 : 24-26. 



This is a typical member of the genus Eurythrips as defined by Stannard (1957). 

 The praepectus is well developed and the pelta is broadly semicircular. The lateral 

 abdominal setae of segments II to VI and VIII have expanded apices, but the 

 extreme lateral pair on VII are finely acute and the median lateral pair are slightly 

 flattened.

The above synonymy is based on a comparison of type material of the species 

 concerned with several other members of the genus. The chaetotaxy of the anterior 

 margin of the pronotum is very different in elegans and nigrodentatus, but in 

 marshalli Pr. for example the antero-angular setae are reduced and there is more 

 than one seta along the anterior margin of the pronotum. The ocellar cone and 

 lateral abdominal setae are similarly variable. The major setae on tergite IX are 

 acute in elegans and caudatus, but the latter species is related to the other African 

 species treated below. The genus may be defined as follows: 



Head long, 1-5 times as long as wide or longer, weakly projecting in front of eyes ; ocelli 

 sometimes raised on a cone-shaped projection ; no elongate postocular setae, one or two pairs 

 of short stout setae on vertex ; cheeks with several pairs of setae, these frequently stout ; 

 eyes large, mouth cone broadly rounded, maxillary stylets slender, close together, low in head. 

 Antennae eight-segmented, VII and VIII broadly jointed ; one sense cone on III, four on IV 

 although the dorsal one is barely one third as long as the other three sense cones. Pronotal 

 major setae when present short and stout, midlaterals distant from epimeral sutures ; epimeral 

 sutures complete ; praepectus absent, mesopraesternum very well developed. Metanotum 

 reticulate, longitudinally in anterior half. Fore tarsus with a tooth in both sexes ; fore wing 

 broad with numerous accessory cilia, basal setae never elongate. Pelta small, triangular, 

 reticulate ; tergites with eight or more pairs of accessory wing retaining setae in addition to at 

 least two pairs of sigmoid setae ; posterolateral tergal setae short and stout ; tube long, 

 reticulate with weak decumbent hairs. Ten nominal species placed in this genus have not been
