Cerococcus andinus Leonardi, 1911 (Cerococcidae: Cerococcus)

Nomenclatural History

• Cerococcus andinus Leonardi 1911a: 11. Type data: ARGENTINA: Cacheuta, on Tricycla patagonica, 15/02/1909, by L. Iches. Syntypes, female, Type depository: London: The Natural History Museum, England, UK; Portici: Dipartimento de Entomologia e Zoologia Agraria di Portici, Universita di Napoli Federico II, Italy; 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 that adult female paratypes are in the USNM, however, since no evidence of a holotype can be found, they must be considered syntypes. There are 2 slides in the USNM, 1 in BMNH, 3 at VPIC and there are two dried specimens and two slides of material in IFSP. There has been some confusion about the collector of the type material. Lambdin & Kosztarab (1977a) give the collector as Leonardi, but it is clear from Leonardi's original description that the material was collected by L. Iches and sent to Leonardi by F. Lahille.

Remarks

• Systematics: Cerococcus andinus is close to C. tuberculus (Hamon & Kosztarab, 1979). It can be told from the latter by the cribriform plates arranged in 2 submedian pairs with anterior plates larger than posterior plates; pair of bullet-shaped setae present on each anal lobe; large tubular ducts near vulva, each with 4-7 conical spines (Lambdin & Kosztarab, 1977a).
• Structure: Female test is light to dark brown. Median and submarginal carinae present. Anal orifice prominent. Male test elliptical, yellow, indistinct transverse ridges common on cephalothoracic and anterior abdominal areas. Adult female is pear shaped with membranous derm, 8-shaped and simple pores, tubular ducts and slender setae on dorsum (Lambdin & Kosztarab, 1977a) The adult female of C. andinus is characterised by the following combination of character-states: (i) 8-shaped pores on dorsum not in a reticulate pattern but in a sparse swirled pattern; (ii) 8-shaped pores on dorsum of just one size; (iii) apex of each stigmatic band with two or three 8-shaped pores; (iv) two–four cribriform plates present submedially on each side of abdominal segment IV; (v) tubular ducts of 2 sizes present, broadest medially on posterior abdominal segments, narrower abundant elsewhere; (vi) multilocular disc-pores present in bands one-pore wide across abdominal segments II–VI but absent on metathorax; (vii) stigmatic pore bands bifurcated; (viii) stigmatic pore bands with few spiracular disc-pores, and (ix) leg stubs absent.
