Sananicoccus, Huang & Yan, 2023

Huang, Shaobin & Yan, Meiyu, 2023, A new genus and species of Phenacoccinae (Hemiptera: Coccomorpha: Pseudococcidae) from northwestern China, Zoological Systematics 48 (3), pp. 227-235 : 228

Genus Sananicoccus gen. nov.

Type species: Sananicoccus nanophytoni sp. nov.

Diagnosis. Body of adult female broadly oval, membranous. Antennae each with 7 segments. Legs well-developed, claw with a denticle. Anal ring situated at apex of abdomen, bearing 6 setae. Both ostiole pairs and circulus absent. Cerarii numbering 18 pairs, each usually with 1 or 2 conical setae and 1 or 2 trilocular pores. Dorsal setae minute, conical; ventral setae flagellate. Dorsum with large tubular ducts, each usually with 2 discoidal pores situated next to orifice. Multilocular pores and quinquelocular pores restricted to venter only; trilocular pores present on dorsum only. Oral collar tubular ducts present on both surfaces.

Etymology. The new genus is dedicated to Dr. San’an Wu, who has made significant contributions to coccoid fauna of China.

Remarks. The new genus is similar to the genus Synacanthococcus Morrison, 1920 by sharing the large dorsal tubular ducts each with discoidal pores next to the orifice and absence of anterior ostioles, but differs by Synacanthococcus possessing posterior ostioles and dorsal cerarii, and all cerarii, including dorsal and marginal cerarii, each situated on a prominent sclerotized area.

The genus Synacanthococcus was established by Morrison (1920), with S. bispinosus Morrison as type species. It was once synonymized with Spinococcus Borchsenius, 1949 by Balachowsky (1953). Tang (1992) followed the treatment. But most researchers such as Williams (2004) considered it as a valid genus. Only 3 species of the genus were recorded till now, one from Palaearctic Region, and another two from Oriental Region.
