COMMENTS. Only a single slide of
syntype
material was available for study, housing three parasitised puparia. This is clearly the slide mentioned by
Quaintance
&
Baker
in their original description – “
Type
no.14765 ….. three parasitized specimens in balsam mount”. This slide had a third label affixed on top of one of the original two, with the data “Q.2975,
Yucatan
, 1904”, and this label has now been transferred to the obverse surface of the slide, to reveal the earlier label. The original two labels bear the data “
Aleurodicus coccolobae
Quaintance & Baker
,
Type
no. 14765 USNM” and “2975 Q.,
Aleurodicus
n. sp.
?, 1/28/04,
Progreso, Yucatan
”. A fourth label has now been added, on the obverse, with details of the
lectotype
designation. The specimens on the
lectotype
slide had clearly not been treated for removal of waxy secretions, and all are still occupied by parasitoid pupal material, but most of the main characteristics are visible on
one specimen
which is
here designated
the
lectotype
and is indicated as such on a new slide label. A slight advantage of these specimens not having been treated for wax removal is that the emergence of secretion from the main types of simple pore is clearly visible, a character not seen in fully-prepared specimens on slides
.
A. coccolobae
is one of the species that
form the
dispersus
-group (
Russell, 1965
), a natural grouping within
Aleurodicus
, whose puparia either lack small compound pores entirely, or have only one pair present (on abdominal segment VII) along with particularly dense provision of dorsal disc pores of
four types
, and submedian thoracic setae much reduced in size. This small species-group was discussed by Russell as part of her description of
A. dispersus
, the spiralling whitefly. The appearance of
A. coccolobae
and
A. dispersus
puparia in life may be compared in figures 123 and 122 respectively.
