Capitisetella Hambleton, 1977 (Rhizoecidae)

Capitisetella Hambleton 1977: 40. Type species: Pseudorhizoecus migrans Green by monotypy and original designation . accepted valid name

Systematics: The adult male of Capitisetella is clearly structurally similar to that of Pseudorhizoecus, only really differing in: (i) the type of dermal setae (capitate on apitisetella, small setose on Pseutorhizoecus), (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 Capitisetella and intersegmental on Pseudorhizoecus), and (iv) the number of antennal segments (3 on Capitisetella and 5 or 6 on Pseudorhizoecus. The adult females of these two species are rather similar: capitate setae on Capitisetella, small setose on Pseudorhizoecus; 3 antennal segments on Capitisetella, and 5 on Pseudorhizoecus; differently structured trilocular pores; and an anal ring with 6 setae and a few obscure pores on Capitisetella but that of Pseudorhizoecus with 2-5 short seta and with >20 small protuberances. Whether these differences aresufficient to justify keeping the two separate genera is unclear. Both Capitisetella and Pseudorhizoecus are monotypic and the discovery of further species in either genus might make their status clear. (Hodgson, 2012)
