Cerococcus koebelei Cockerell

Cerococcus koebelei (Cockerell) Solenophora koebelei Cockerell 1898 b: 429. Solenococcus koebelei; Cockerell 1899: 392. Change of combination. Cerococcus koebelei; Ferris 1955: 38. Change of combination. Type details. MEXICO, Tulare (probably Toluca), on Crataegus sp. and Prunus demissa (Rosaceae), 8.viii. 1897, A. Koebele. Depositories: USNM: lectotype adf (designated by Lambdin & Kosztarab 1977: 140): labelled Solenococcus (crossed out) koebelei (Ckll) on Crataegus and Prunus emissa, Tulon (probably Toluca), Mexico Koebele # 1659, Aug. 8 ��� 97: 1 / 2 adff [lectotype specimen circled] + 1 / 1 paralectotype first-instar nymph, same data as lectotype. Also 1 / 7 adff, labelled paralectotypes (label data: Solenophora koebeli (Ckll), on Crataegus, Toluca-Mex., Koebele # 1362, Aug 8 ��� 97, Type). Also a slide with same data labelled just Cotype. Miller (pers. comm.) considered that the correct locality is Toluca, not Tulare or Tulon. BME: paralectotype? ff: slide labelled ��� Solenococcus koebelei Ckll, Mexico, (with a red label stating type material), on Crataegus sp., Bremner coll. No. 225. GFF���: 1 / 1 adff + 2 nymphs (dried specimens mounted on slide); also 4 / 7 adff with same data (probably f-p). Also from Koebele collection, no. 1632: Solenococcus koebelei Ckll, on?host, Mexico City: 1 / 2 adff (possibly quite g) and 1 / 2 adff (dried specimens mounted on slide); also S. koebelei, Mexico, Toluca or Amecameca, on Tejocote (Crataegus mexicanus) or Crataegus sp.: 1 / 1 adf (f). Material examined. MEXICO, Zinacantepec, Manzana, no host, 1.iii. 1960, L. Leyva Guz (BMNH): 1 / 2 adff (f���g). Comment. Lambdin and Kosztarab (1977) provide a good description. In the above material, the apex of each stigmatic pore band is transversely split by a band of small 8 -shaped pores, and there is a seta in amongst the discpores near the apex. The adult female of C. koebelei is characterised by the following combination of character-states: (i) 8 -shaped pores on dorsum randomly distributed, not in a lattice-like pattern; (ii) 8 -shaped pores on dorsum of three sizes, all quite small; (iii) larger 8 -shaped pores restricted to near stigmatic pore bands; smallest pores restricted to within stigmatic pore bands; (iv) cribriform plates elliptical, present in submedial groups of two on each side of abdominal segment IV, anterior plate larger and more elliptical than posterior plate; (v) dorsal tubular ducts of two sizes present, broader ducts restricted to posterior abdominal segments; narrower ducts frequent elsewhere; (vi) multilocular disc-pores present in broad bands across all abdominal segments and also metathorax; (vii) stigmatic pore bands bifurcated; (viii) stigmatic pore bands with fairly abundant spiracular disc-pores, and (ix) leg stubs present. In the key to adult females of Cerococcus, C. koebelei keys out close to C. catenarius from South America.
