ALEUROGLANDULUS Bondar

Aleuroglandulus Bondar, 1923: 121 . Type species Aleuroglandulus subtilis , by monotypy.

DIAGNOSIS AND COMMENTS. As interpreted here, Aleuroglandulus comprises species with the following combination of puparial characters: usually prothorax, and often also abdominal segment III, with a glandular area on each side of body ( Figs 35, 37 , 89), the glands variably defined but usually at least staining more darkly than remainder of puparium; thoracic and caudal tracheal combs present, the teeth much differentiated from remainder of margin but margin not indented; vasiform orifice subcordate, lingula exposed but mostly included within orifice boundary, lingula head lobulate; a distinct caudal furrow leading from vasiform orifice to posterior puparial margin ( Figs 28 , 29 , 36 ).

Russell (1944) revised this genus, describing three new species. The present study leads the author to the conclusion that two of Russell’s species should be regarded as junior synonyms of the type species, A. subtilis Bondar , but that one colony found in Belize represents a new species which is here described. With these changes to a previously revised genus, an alternative key to species is provided, below .
