Exallomochlus philippinensis Williams



Field characters

We have been unable to find a description of the field characteristics of this species in the literature. Body usually rotund. Based on morphology of slide mounted female, probably with 18 pairs of lateral filaments and without an ovisac. On stems and fruit of host.

Validation characters

Discoidal pores normal, circular; cerarian setae with acute apices; ventral multilocular pores on abdominal segments VI, VII, and VIII; ventral oral-collar tubular ducts restricted to abdomen; dorsal setae less than 55 µ long; most cerarii with 3 or more conical setae; circulus present and rectangular or hour-glass shaped; translucent pores on hind coxa and tibia.


Within Exallomochlus this species is most similar to E. sulawesicus Williams by having simple circular discoidal pores, cerarian setae with acute apices, translucent pores on hind coxa and tibia, elongate and somewhat enlarged dorsal filamentous setae, and ventral multilocular pores restricted to abdomen. Exallomochlus philippinensis differs by having dorsal setae short, less than 55 µ long, whereas, on E. sulawesicus they are long, greater than 85 µ.

U.S. quarantine notes

This species was intercepted 12 times at U. S. ports-of-entry between 1995 and 2012, with specimens originating from The Philippines, and Thailand. We also have examined specimens taken at U. S. ports-of-entry from The Philippines on Euphorbia, Lansium, Manilkara, Melicoccus, and Nephelium. ScaleNet lists the species in the families Costaceae, Meliaceae, Sapindaceae, and Sapotaceae, and distribution records include The Philippines only. One other species of Exallomochlus other than E. camur Williams, E. hispidus (Morrison), and E. philippinensis has been taken in quarantine, E. liti Williams (The Philippines, on Poikilospermum and Lansium).
