Parasaissetia nigra ( Nietner, 1861) 

( Figs 45 View Figure , 46 View Figure )

Lecanium nigrum Nietner, 1861: 9  .

Diagnosis. Dorsum with anal plates each with 4 apical setae ( Figs 45D View Figure , 46E View Figure ); and preopercular pores present anterior to anal plates ( Fig. 46D View Figure ). Marginal setae with broadly fimbriate apices ( Fig. 46K View Figure ). Venter with multilocular disc-pores usually each with 10 loculi, mainly present around vulvar area ( Fig. 46F View Figure ); tubular ducts each with a narrow inner ductule ( Fig. 46G View Figure ); antenna 7 or 8 segmented (partially adopted from Williams & Watson 1990).

Material examined. 2 ♀♀, LAOS, Hadsayfong Dist., Vientiane Capital, 16.ii.2017, coll. P.P. Soysouvanh, on Cnidoscolus aconitifolius (Mill.) I.M. Johnst.  ( Euphorbiaceae  ).

Hosts. Polyphagous. According to García Morales et al. (2016), P. nigra  has been recorded from plants belonging to 242 genera in 92 families. In Laos, it has been found on Euphorbia  sp. ( Euphorbiaceae  ) and Musa  sp. ( Musaceae  ) ( Hodgson 1994).

Distribution. All zoogeographical regions; Oriental Region ( India, Indonesia, Laos, Malaysia, Philippines, Sri Lanka, Taiwan, Thailand, and Vietnam) ( García Morales et al. 2016).

Economic importance. Hamon & Williams (1984) and Hodgson (2000) considered P. nigra  to be a pest on diverse ornamental plants in tropical regions; it was also regarded as a potential pest of citrus and avocado ( Persea americana  ) in California ( Smith 1944).

Remarks. Parasaissetia nigra  is easily recognized by the following morphological combination: (i) dorsum with reticulated pattern; (ii) having 3 stigmatic spines; and (iii) lacking ventral tubular ducts in the medial area of the abdomen ( Hodgson 1994).
