Aztecencyrtus iceryae (Howard) : Noyes 1980 : 180 ; Trjapitzin et al. 2004 : 52 . Type locality Kingston , Jamaica . Type material examined Holotype female, in poor condition, on point (mesosoma and a forewing) and a card (metasoma and leg parts) [ USNM ], labeled: 1. “ Holotype ”; 2. “Kingston J. 1892”; 3. “4650°”; 4. “Type No. 1490 U.S.N.M.”; 5. “ Cerchysius iceryae How. Type”; 6. “female Cerchysius iceryae Howard det. J.S. Noyes , 1978 HOLOTYPE ”. One forewing from the holotype was slide­mounted at UCRC in Canada balsam in 2005. Distribution Jamaica . Host Crypticerya rosae (Riley & Howard) (Howard 1892) . Comments FIGURES 9, 10. Brethesiella iceryae (female, holotype). 9. Forewing. 10. Forewing venation. Member of the flava species group. The forewing of the holotype female ( Fig. 9 ) is about 2.9x as long as wide. Somewhat similar in coloration of the body (especially the gaster) and infuscation of the forewing to B. flava ; however, in B. iceryae ( Fig. 10 ) the stigmal vein of the forewing is notably longer than the postmarginal vein (about equal in length in B. flava , Fig. 8 ), also these two veins are at a notably wider angle to each other and the area between them is significantly more setose in B. iceryae than in B. flava . Acknowledgments We thank Vladimir V. Berezovskiy (UCRC) for dissecting and slide­mounting two of the paratype specimens of the new species in Canada balsam, and Michael W. Gates for the loans of the type material from the USNM . John S. Noyes ( BMNH ) made many useful suggestions on the initial draft of the manuscript. Svetlana N. Myartseva ( Universidad Autónoma de Tamaulipas , Ciudad Victoria , Tamaulipas , Mexico ) kindly let us examine the specimens of Brethesiella reared by her in Mexico . References Annecke, D.P.
