Green, 1889 : 249 Review of the family Coccidae (Hemiptera: Coccomorpha) in Laos Choi, Jinyeong Soysouvanh, Pheophanh Lee, Seunghwan Hong, Ki-Jeong Zootaxa 2018 2018-08-17 4460 1 1 62 43DZC (Green, 1889) Green 1889 [151,639,1220,1246] Insecta Coccidae Milviscutulus GBIF Animalia Hemiptera 41 42 Arthropoda species mangiferae     Lecanium mangiferae  Green, 1889: 249 Diagnosis.Dorsum with anal plates pyriform, each with 4 apical setae ( Figs 37D, 38E); dorsal setae clavate ( Fig. 38F); duct tubercles present ( Fig. 38D). Marginal setae spinose, mostly with fimbriate apices ( Fig. 38M). Venter with multilocular disc-pores usually each with 7–10 loculi, present on posterior area of abdomen, occasionally with a few laterad of metacoxa ( Fig. 38K); antenna 8 segmented ( Fig. 38P) (partially adopted from Williams & Watson 1990; Hodgson 1994).   Material examined.3 ♀♀, LAOS, Phou Khao Khuay National Bio-Diversity Conservation Area, Thaphabath Dist., Bolikhamsai Prov., 4.v.2015, coll. J.Y. Choi, on  Mangifera indicaL. ( Anacardiaceae); 1 ♀, Vangvieng Dist., Vientiane Prov., 8.ii.2017, coll. P.P. Soysouvanh, on  Chrysalidocarpus lutescensH. Wendl. (Arecaceae).   Hosts.Polyphagous. According to García Morales et al. (2016),  M. mangiferaehas been recorded from plants belonging to 82 genera in 42 families. In Laos, it has been found on  Dracaenasp. ( Asparagaceae) and  Ficussp. ( Moraceae) ( Suh & Bombay2015).   Distribution.All zoogeographical regions;  OrientalRegion( India, Indonesia, Laos, Malaysia, Philippines, Singapore,  SriLanka, Taiwan, Thailandand Vietnam) ( Suh & Bombay2015; García Morales et al. 2016).  Economic importance.  Milviscutulus mangiferaewas listed as a major pest of mango (  Mangifera indica) in Israel, U.S.A.and the Pacific region ( Gill & Kosztarab 1997), causing yellowing, leaf drop, and death of branches ( Grimshaw & Donaldson 2007).   Remarks.  Milviscutulus mangiferaeis closely related to  M. spiculatus Williams & Watson, 1990, but is easily differentiated by having clavate or capitate dorsal setae and mostly fimbriate marginal setae; in contrast,  M. spiculatushas flagellate to lanceolate but never bluntly clavate or capitate dorsal setae, and the marginal setae are mostly pointed. For comparisons with other species of  Milviscutulus, see Williams & Watson (1990).
