S. baltazari Rimando, 1962 View in CoL

Geographical distribution – This species was first reported by Rimando (1962) in citrus ( Rutaceae ) from Philippines, later it was reported in Hong Kong, Myanmar and India on citrus ( Manson 1963); on Lansium domesticum (Meliaceae) in Taiwan ( Lo 1968), Thailand ( Ehara and Wongsiri 1975), and Indonesia ( Ehara 2004); on Mallotus japonicus (Euphorbiaceae) in Japan (Kazunori Ohashi et al. 2009), and in Dioscorea sp. (Dioscoreaceae) from Thailand ( Ehara and Wongsiri 1975). In India reported in citrus spp., Murraya koenigii (Rutaceae) and Azadirachta indica (Meliaceae) ( Manson 1967; Prasad 1974; Gupta 1991; Gupta and Gupta 1994).

Juss .

Remarks – Mite infests both leaves and fruit in case of citrus, in neem and curry leaves. Young female lays eggs underneath web silks to protect progenies from predators and abiotic stress. They feed below web and these spots are visible like white or silvery spots. Shape of aedeagus of S. baltazari resembles S. hindustanicus ( Hirst, 1924) . It only differs from the latter in absence of posterior extension of aedeagal knob. Both mites are reported from citrus ( Navia and Marsaro Jr 2010). This mite is a threat in curry leaves and citrus; it greatly reduces the quality of leaves and yield respectively and imposes huge financial burden in form of management practices on farmers.
