status

 

Eucalymnatus tessellatus ( Signoret, 1873) 

( Figs 30 View Figure , 31 View Figure )

Lecanium tessellatum Signoret, 1873: 401  .

Diagnosis. Dorsum with setae bluntly spinose ( Fig. 31B View Figure ); duct tubercles present ( Fig. 31A View Figure ). Marginal setae spinose, with pointed or fimbriate apices ( Fig. 31I View Figure ). Venter with multilocular disc-pores each usually with 7 loculi, present around vulvar area and few on anterior area of abdomen ( Fig. 31E View Figure ); pregenital setae numbering 1 pair ( Fig. 30D View Figure ); antenna 7 or 8 segmented ( Fig. 31J View Figure ) (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.

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.
