Diagnosis. Dorsum with setae bluntly spinose ( Fig. 31B ); duct tubercles present ( Fig. 31A ). Marginal setae spinose, with pointed or fimbriate apices ( Fig. 31I ). Venter with multilocular disc-pores each usually with 7 loculi, present around vulvar area and few on anterior area of abdomen ( Fig. 31E ); pregenital setae numbering 1 pair ( Fig. 30D ); antenna 7 or 8 segmented ( Fig. 31J ) (partially adopted from Hodgson 1994 ). Material examined. 1 ♀ , LAOS , Saythany Dist. , Vientiane Capital , 25.ii.2017 , coll. P.P. Soysouvanh , on Gardenia sp. ( Rubiaceae ). Hosts. Polyphagous. According to García Morales et al . (2016) , E. tessellatus has been recorded from plants belonging to 109 genera in 54 families. FIGURE 30. Eucalymnatus tessellatus (Signoret, 1873) . A, female in life; B, slide-mounted adult female; C, polygonal plates; D, pregenital setae. Scale lines for B = 0.5 mm; C = 200 µm; D = 100 µm. Distribution. All zoogeographical regions; Oriental Region ( India , Indonesia , Malaysia , Taiwan , Thailand , and Vietnam ) ( García Morales et al . 2016 ); Laos (new country record). Economic importance. Eucalymnatus tessellatus has been reported as a minor pest on ornamental plants in California ( Gill 1988 ) and Florida ( Hamon & Williams 1984 ). Remarks. Gill et al . (1977) noted that the teneral adult female of Eucalymnatus tessellatus , without the sclerotisation of the polygonal plates, is similar to C. longulus (Douglas) but differs from it by lacking subdiscal setae on the anal plates.
