A review of neococcid scale insects (Hemiptera: Sternorrhyncha: Coccomorpha) based on the morphology of the adult males Author Hodgson, Chris text Zootaxa 2020 2020-04-16 4765 1 1 264 journal article 22494 10.11646/zootaxa.4765.1.1 8af5a092-f062-48c7-8d7c-f96ae6282bfa 1175-5334 3774174 urn:lsid:zoobank.org:pub:C442D94C-0EB4-4509-B762-913707214819 Stibococcus Miller & González 1975 Stibococcus Miller & González 1975 , 154–156. Type species: Stibococcus cerinus Miller & González by monotypy and original designation. Introduction. The genus Stibococcus contains one species, S. cerinus Miller & González , collected on Myrceugenia bridgesii ( Myrtaceae ) in Chile . The adult female is naked, shiny and pale green. It secretes a long ovisac from wax glands on the underside of its abdomen. Immature stages feed on the underside of the host plant leaves, causing a gall-like distortion which is visible from above ( Miller & González, 1975 ). The adult male was originally described and illustrated by Miller and González (1975) . The same illustration is repeated here ( Fig. 38 ). Generic diagnosis based on adult male morphology ( Fig. 38 ). Body : abdomen more or less parallel sided; body setae few, perhaps mainly hs. Head: simple pores present; ocular sclerite with a few reticulations; dorsal midcranial ridge well developed; preocular ridge short; genal setae present ; antennae 10 segmented ; flagellar segments either without fs or with hs and fs indistinguishable; capitate setae present on apical antennal segment only . Thorax: prosternal median ridge present; scutal setae present laterally; scutellum with scutellar setae; postmesospiracular setae present ; basisternal setae present; metasternum with few setae; metaprecoxal ridge absent; postmetaspiracular setae possibly absent; tibial and tarsal setae apparently all setose; tarsi 2 segmented; claw digitules capitate; claws elongate, usually with a denticle. Abdomen: glandular pouches present on segment VIII; penial sheath with longest setae posteriorly; style broad anteriorly, becoming sharply pointed posteriorly and only a little longer than basal width of segment IX. Comment. Adult males of S. cerinus are rather similar to those of Carpochloroides viridis , also from the Neotropics. For main differences see key to the Gondwanan group of eriococcids above.
