(Gullan, P.J., 1984) [10] (adult female; Adult females and female galls of Apiomorpha)

GENERAL

The most comprehensive treatment of this species is by Gullan, P.J. 1984. A revision of the gall-forming coccoid genus Apiomorpha Rübsaamen (Homoptera: Eriococcidae: Apiomorphinae). Australian Journal of Zoology, Supplementary Series 97: 1–203 who described the adult female, both sexes of gall, and gave photos of the galls.

BIOLOGY

Female galls are produced on stems, umbels and galls of other females. Male galls are found on both leaf surfaces with no tendency to grow near the midrib (see Gullan, P.J. 1984. A revision of the gall-forming coccoid genus Apiomorpha Rübsaamen (Homoptera: Eriococcidae: Apiomorphinae). Australian Journal of Zoology, Supplementary Series 97: 1–203).

SYSTEMATICS

Slide-mounted adult female is characterized by having: abdominal segment IX with ventral and dorsal lengths subequal, not fused with abdominal segment VIII; abdominal segment IX with posterior margin fused with anal lobes; body not slender; dorsum of head and thorax with small spine-like setae; anal lobes with bifurcate apices (see Gullan, P.J. 1984. A revision of the gall-forming coccoid genus Apiomorpha Rübsaamen (Homoptera: Eriococcidae: Apiomorphinae). Australian Journal of Zoology, Supplementary Series 97: 1–203).

STRUCTURE

Female gall obconical to obovoid to fusiform, apex usually truncate. Male gall tubular, apex dilated (see Gullan, P.J. 1984. A revision of the gall-forming coccoid genus Apiomorpha Rübsaamen (Homoptera: Eriococcidae: Apiomorphinae). Australian Journal of Zoology, Supplementary Series 97: 1–203).
