SINGHIELLA Sampson

Singhiella Sampson, 1943: 211 . Type species Trialeurodes bicolor Singh, 1931: 50–52 , by original designation and monotypy.

DIAGNOSIS AND COMMENTS. Jensen (2001) has redefined Singhiella as comprising species from the Dialeurodes ­group with the following combination of characters: some or all dorsal pores situated on rounded papillae (which may be very shallow); outer edges of legs without ornamentation; front and middle legs not contiguous; usually with three or more pairs of dorsal pores on abdominal segment I; often with minute basal spinules on antennae.

As redefined by Jensen, Singhiella now comprises 29 described species. All of these were described from the palaeotropics, except for S. citrifolii (Morgan) which is the only species known from Belize, and whose origins are discussed below.
