COMMENTS.
Russell (1944)
described three new species of
Aleuroglandulus
—
A. emmae
,
A. magnus
and
A. malangae
—each from very small numbers of specimens.
A. emmae
and
A. magnus
were described from seven and
six specimens
, respectively, taken from herbarium specimens or from quarantine interceptions, with even these small sample sizes representing two separate collections (
A. magnus
) and four collections (
A. emmae
). Although Russell said of the
type
sample of
A. malangae
“the insects [puparia] were abundant on the leaves submitted”, the description was prepared from only eight slidemounted individuals. Such small samples, especially where these represent several individual collections, do not allow an assessment of variability in such notoriously fluid characters as the sizes of glandular patches or the precise numbers of teeth in tracheal combs. Study of material in BMNH indicates that all specimens possessing the combination of legbase spines, vasiform orifice inset from puparial margin by less than its own length, and welldefined prothoracic glands should be regarded as conspecific. Two large slidemounted samples (
Costa Rica
, on
Colocasia
cultivar, n=50+;
Belize
, on
Schizolobium parahybum
, n=35) clearly indicate that the thoracic tracheal combs are highly variable within colonies. In contrast, two very small samples (
Panamá
, on
Erythrina fusca
, n=5 and unidentified host, n=2) demonstrate that the glands on abdominal segment III can vary from quite large to entirely absent within an individual colony, and the thoracic tracheal teeth from distinctacute to hardly discernible. For these reasons, the decision has been taken to propose
A. emmae
and
A. malangae
as junior synonyms of
A. subtilis
.
