Dong & Wu
accepted valid name
- Systematics: When describing Dysmicoccus muajatae, Williams (2004) considered it to be a strange species with no known relatives in the family Pseudococcidae at that time, and suggested that there might be a reason to place it in a new genus near Pedronia Green, 1922 in the future. With the aim of reducing the degree of heterogeneity in Dysmicoccus, a new genus was described by Dong, Zhang and Wu, 2017, to include these two species (Dysmicoccus muajatae and Dorsoceraricoccus ningboensis.
The genus Dorsoceraricoccus Dong & Wu is definitely a member of the subfamily Pseudococcinae as defined by Hardy et al. (2008), based on having antenna with 7 or 8 segments, claw without a denticle, absence of quinquelocular pores, blunted tarsal digitules, and anal ring with pores with spine-like setae. In Pseudococcinae, this genus resembles Dysmicoccus in sharing many common characteristics such as (i) lateral cerarii fewer than 18 pairs; (ii) oral rim ducts absent; (iii) anal lobe bar absent; (iv) claw without denticle, but differs from Dysmicoccus in possessing dorsal cerarii. It may be related to Pedronia Green, 1922 due to the presence of dorsal conical setae and dorsal cerarii, and anal lobe cerarii each bearing 2 conical setae, but differs from Pedronia as follows (the condition in Pedronia in parentheses): (i) anal lobe bar absent (present); (ii) cerarii always recognisable by a concentration of trilocular pores (trilocular pores sometimes absent from dorsal cerarii); (iii) conical setae (including cerarian setae) are situated on a membranous or slightly sclerotized areas (conical setae situated on strongly sclerotized cuticular tubercles). Dorsoceraricoccus is also very similar to Pedrococcus Mamet, 1942, but according to Williams (2004), in Pedrococcus the trilocular pores in the lateral and dorsal cerarii are much smaller than those on other body surfaces (all the same size in Dorsoceraricoccus, and oral collar tubular ducts are completely absent (present in
