Antecerococcus royenae (Brain, 1920) (Cerococcidae: Antecerococcus)

Nomenclatural History

• Cerococcus royenae Brain 1920: 121. Type data: SOUTH AFRICA: Orange Free State, Fauresmith, on Royena pallens, ?/03/1915, by J.C. Faure. Syntypes, female, Type depository: Blacksburg: Department of Entomology, Virginia Polytechnic Institute and State University, Virginia, USA; London: The Natural History Museum, England, UK; Pretoria: South African National Collection of Insects, South Africa; Washington: United States National Entomological Collection, U.S. National Museum of Natural History, District of Columbia, USA; accepted valid name Notes: Lambdin & Kosztarab (1977a) state they have examined paratypes, but since no mention of a holotype is made in Brain's original description, the type material must be considered syntypic.

Remarks

• Systematics: Lambdin and Kosztarab (1977) considered that the additional setae (medioventral, anteroventral, etc.) associated with the anal area were on the inner margins of the anal lobes and that all multilocular disc-pores were on the abdomen. However, the material seen by Lambdin and Kosztarab was studied again by Hodgson and Williams (2016) and it was clear that these pores are present both laterad and mesad to the metathoracic leg stubs. The layout on A. royenae may, therefore, be the same as that on A. kakamegae that closely resembles it.
• Structure: Test of adult female is almost as broad as high, very roundly convex, with a short caudal prominence around the aperture. Test is thick and brittle and a dull orange-brown in color. Mounted female is almost circular with the caudal extremity slightly produced (Brain, 1920). The adult female of A. royenae appears to be unique in the distribution of the long ventral setae associated with the anal lobes and anal ring, with two pairs of extra-long setae ventrally (medioventral and anteroventral setae) in addition to the preanal pair; in addition, the small companion setae just anterior to the preanal setae is also unusully long. Other character-states that are important in diagnosing this species are: (i) dorsum with two sizes of 8-shaped pores, each very similar in size; (ii) larger 8-shaped pores (i.e. 10 x 6.5 μm) restricted to either side of and within each stigmatic pore band; (iii) large 8-shaped pores (i.e. those >15 μm widest) entirely absent; (iv) one pair (usually) of large, oval cribriform plates on abdominal segment IV; (v) leg stubs present; (vi) posterior stigmatic pore bands bifurcated; (vii) multilocular disc-pores present across anterior five segments and metathorax; (viii) stigmatic pore bands very sparse; (ix) simple pores in a transverse band associated with cribriform plates, and (x) antennae long and sometimes appearing two segmented, with a distinct cone-shaped point but no setal cavity.
