Sueus sphaerotrypoides Murayama 1951: 2 . Synonymy: Wood 1983: 650 . Type material. Hyorrhynchus niisimai holotype , female, Japan , Urakawa (Hakodate), USNMENT01547084 (examined). Sphaerotrypes controversae lectotype , female, Japan , Kochi Pref., Daidominamiyama , Shikikiu (examined). Sueus sphaerotrypoides holotype , female, Japan , Wakayama Pref. , Nishimuro County , Ohshima Vill , Sue ( NMNH ) (examined) . Other specimens examined. Vietnam : Ninh Binh Prov. , Cuc Phuong NP , 20.34932 , 105.59669 , 431m , 7.iii.2018 , VN 134, SM Smith , AI Cognato , ex standing dead laurel; base of bole, 5 cm ( MSUC _ARC_320284). Additional records in Table 1 . Diagnosis. Length 1.7–2.0 mm, 2.11–2.25 × longer than wide; declivital interstriae bearing minute granules; first fifth of elytral base granulate; main elytral interstrial setae longer than ground vestiture (> width of interstria); ground vestiture shorter than width of an interstria. FIGURE 7 . Sueus niisimai female (MSUC_ARC_320284) 1.7 mm A) dorsal view; B) lateral view; C) frons; D) posterolateral view. Distribution. Found throughout eastern Asia including China ( Fujian , Guangxi , Guizhou , Jiangxi , Zhejiang ), Japan ( Kochi , Okinawa , Wakayama ), South Korea ( Jeju ), Taiwan ( Nantou ), and northern Vietnam * ( Cao Bang , Ninh Binh , Thua Thien Hue). It may have a more northerly distribution than S. pilosus . There are records from Australia , Fiji (introduced), Malaysia , Sri Lanka , and Papua New Guinea ( Beaver 1984 ; Beaver & Gebhardt 2005 ; Li et al. 2020 ) which need verification given potential misidentification with the more southerly distributed S. pilosus . Host. Cornus controversa ( Cornaceae ) ( Murayama 1950 ), Machilus ( Lauraceae ), Ligustrum ( Oleaceae ). Mycetophagous and presumably polyphagous.
