Hodgso2012: pp.49-50 ( Adult (M) ) [Key to the adult males of Rhizoecinae seen during this study:]

Systematics: The adult male of C. migrans is clearly structurally similar to that of Pseudorhizoecus proximus only really differing in: (i) the type of dermal setae (capitate on C. migrans, small setose on Ps. proximus), (ii) the presence/absence of tibial spurs (absent on C. migrans, present on Ps. proximus), (iii) the distribution of the loculate pores (segmental amongst the setae on C. migrans and intersegmental on Ps. proximus), and (iv) the number of antennal segments (3 on C. migrans and 5 or 6 on Ps. proximus). The adult females of these two species are rather similar: capitate setae on C. migrans, small setose on Ps. proximus; 3 antennal segments on C. migrans and 5 on Ps. proximus; differently structured trilocular pores; and an anal ring with 6 setae and a few obscure pores on C. migrans but that of Ps. proximus with 2-5 short seta and with >20 small protuberances. Hodgson (2012) questions whether these differences are sufficient to justify keeping the two species in separate genera. Both Capitisetella and Pseudorhizoecus are monotypic and the discovery of further species in either genus might make their status clear. (Hodgson, 2012)
Biology: Occurring on the roots of its host plants.
