NEW RECORDS OF THE SOFT SCALE INSECTS HOSTS ASSOCIATED WITH THE PROMISING PARASITOID, SCUTELLISTA CAERULEA (FONSCOLOMBE) (HYMENOPTERA:PTEROMALIDAE) IN EGYPT

The present study revises the soft scale insects of the genus Cryptostigma Ferris (Hemiptera: Coccoidea: Coccidae), which comprises a group of New World species associated with ants or bees or of hypogeal habit. It includes 17 species, of which 10 species are new to science. The study is based on the external, mostly cuticular morphology of the adult females and first-instar nymphs. Taxonomic keys based on adult females and known first-instar nymphs are provided. For each species a description or redescription is given, followed by information on its distribution, host plants, and known biological information including associated ants or bees. The new species described are Cryptostigma chacoensis sp. nov., C. gullanae sp. nov., C. jonmartini sp. nov., C. longinoi sp. nov., C. melissophilum sp. nov., C. mexicanum sp. nov., C. philwardi , sp. nov. C. rhizophilum sp. nov., C. serratum sp. nov., and C. tuberculosum sp. nov. Neolecanium urichi (Cockerell) is transferred to Cryptostigma as C. urichi (Cockerell) comb. nov., and C. quinquepori (Newstead) is synonymized with Cryptostigma urichi, comb. nov. Lectotypes are designated for Cryptostigma saundersi Laing, Lecanium silveirai Hempel, Lecanium urichi Cockerell and Akermes quinquepori Newstead. Cryptostigma inquilina (Newstead) is amended to C. inquilinum in order to match the neutral ending “stigma”. The following names are treated as nomina nuda: Cryptostigma jamaicensis and Lecanopsis jamaicensis (Ben-Dov, 1993: 97).

Two African soft scale insects, Toumeyella lomagundiae Hall and T. obunca De Lotto, are transferred to Hallicoccus gen. nov. The adult females of both species are redescribed, and the first-instar nymph of T. lomagundiae is described. A revised taxonomic key to separate the adult females is provided. The affinity of Hallicoccus gen. nov. with the genus Toumeyella Cockerell is briefly discussed.

Due to an oversight, the depositories of the new species, Coccus giliomeei Łagowska & Hodgson, and of the new material of Coccus rhodesiensis (Hall) collected in the Transvaal, South Africa, was omitted from the manuscript. Both lots of slides will be deposited in SANC, The South African National Collection of Insects, Pretoria, South Africa.

Host Plant Specificity

Myrmecophytic species of the Paleotropical plant genus Macaranga (Euphorbiaceae) have hollow stems that are almost always occupied by ants of the genus Crematogaster and scale insects of the family Coccidae (Hemiptera: Coccoidea). The coccids have a cryptic endophytic lifestyle and are confined to this microhabitat. They are much more diverse than previously recognised. First data are presented on the diversity, prevalence, specificity and distribution of the coccids associated with myrmecophytic Macaranga species. Twenty-two species of Coccidae in total, including 15 previously unknown from Macaranga, were discovered from 19 species of Macaranga in Peninsular Malaysia and Borneo. The original describers tentatively assigned the known coccid species to Coccus (Coccinae) but the Macaranga coccids still require taxonomic research to establish their correct placing. The coccids varied in their host-plant specificity from species that occurred in most of the sampled Macaranga to one species that was found almost exclusively only on a single host species. In addition to their occurrence on Macaranga, only three species, C. macarangae and C. secretus and morphospecies C. 214 were found on rare occasions in the stem interior of a few other myrmecophytes and in a non-myrmecophytic liana, but did not regularly colonise these plants. Most of the coccids can be regarded as highly specific at the plant genus level.
