072E8795FFC79162FF3B30EAFC60FDB6.taxon	discussion	Comments: The unusual morphology of this genus makes it is difficult to discuss possible similarities with other ortheziids. Characters in this species that are unlike any found in other ortheziids include: the struc- ture and position of the anal opening; the size and shape of the antennae; the structure of the mesosternal and metasternal apopyhyses; the lack of both wax plates and an ovisac band, and the occurrence of only 2 sensoria on each surface of the trochanter. The adult male is unique by having the aedeagus situated ventrally and oriented anteriorly, with a hinge structure near the apex of the abdomen. Characters that might be useful in discovering affinities between Acropygorthezia and other genera include: the number of abdominal spiracles; the position of the abdominal spiracles, and the fusion of the tibia and tarsus. Genera that contain species with a fused tibia and tarsus include Newsteadia, Matileortheziola Kozár and Foldi, Mixorthezia Morrison, Nipponorthezia Kuwana, and Ortheziola Šulc. Genera that contain species with dorsal abdominal spiracles include Arctorthezia Cockerell, Graminorthezia Kozár, Insignorthezia Kozár, Matileortheziola, Orthezia Bosc d’Antic, and Praelongorthezia Kozár. Genera that have species with 7 pairs of abdominal spiracles include Arctorthezia, Graminorthezia, Insignorthezia, and Praelongorthezia.	en	Lapolla, John S., Burwell, Chris, Brady, Seán G., Miller, Douglass R.

Anal ring without obvious opening. Abdominal spiracles apparently absent. Notes: Characteristics of the first instar of this species that are atypical of other scale insects are: the presence of numerous spines, reduced antennae, an anal ring that is located in the middle of dorsum that lacks setae and pores, and fused tibia and tarsus. Mounted adult male (Fig. 3) (based on 3 specimens). Body 1.10 – 1.16 mm long; 0.95 – 0.98 mm wide. Antennae 2 - segmented 112 – 120 µm long; apical segment with 2 enlarged setae, 10 – 12 filamentous setae, and with or without basiconic sensillum; basal segment without setae. Venter.

Spines of 2 sizes: longer spines in medial areas surrounding legs, less dense than marginal spines; shorter spines unusually abundant in submarginal and marginal areas. Setae of 2 types: filamentous setae scattered in small numbers over surface, dome-shaped setae scattered over surface but most abundant on submargin and margin. Quadrilocular or discoidal pores present near thoracic spiracles. Small sized pores present near posterior margin of abdomen.

Dorsum. Spines unusually abundant over surface, present everywhere except in intersegmental areas and in anal area, 6 – 10 µm long. Setae present in small numbers along body margin and in segmental rows, longest about 21 µm long. Quadrilocular pores absent. Small sclerotized pores and small clear pore present posteriorly. Anal ring well developed but without pores, setae, or obvious opening. Abdominal spiracles inconspicuous, 6 pairs in submarginal areas from segments I to VI, with sclerotized vestibule. Penial sheath not visible from dorsum. Notes: The genital structure is quite unusual in that it is strictly ventral and is hinged near the base of the abdomen so that it does not protrude posteriorly. Another characteristic that is atypical of male scales is that the anal ring appears to be well developed and the anus may be functional. Mounted pupal male (Fig. 4) (based on 2 specimens). Body 1.07 and 1.20 mm long; 0.88 and 0.89 mm wide.

Abdominal spiracles inconspicuous, apparently with 6 pairs in submarginal areas from segments I to VI, with sclerotized vestibule. Notes: Many features are difficult to see, especially the spiracles, pores, and segmentation. It is possible that quadrilocular pores are present, but are confused with broken setal bases, and that there is 1 more pair of spiracles. Characteristics of the pupa of this species that are atypical of those of other scale insects are the presence of well-developed legs and the anal structure. Mounted prepupal male (Fig. 5) (based on 2 specimens). Body 1.56 and 1.19 mm long; 0.92 and 0.95 mm wide. Antennae 2 - segmented, 62 and 59 µm long; apical segment with 2 enlarged setae, 2 – 4 filamentous setae, and apparently without basiconic sensillum; basal segment with or without 1 seta. Venter.

Quadrilocular pores or discoidal pores located near thoracic spiracles; small sclerotized pores apparently absent. Genital area ventral, with central conical area and outer flat area with few sensilla on conical area. Dorsum. Spines unusually abundant over surface, present everywhere except in intersegmental areas, genital region, and anal area, about 10 µm long. Setae present in small numbers along body margin and in segmental rows, longest about 10 µm long. Quadrilocular and small sclerotized pores apparently absent. Anal ring without obvious opening. Abdominal spiracles inconspicuous, apparently with 7 pairs in submarginal areas from segments I to VII, with sclerotized vestibule. Notes: Many features are difficult to see, especially the abdominal spiracles, abdominal segmentation, and pores. Characteristics of the prepupa of this species that are atypical of those of other scale insects are the presence of well-developed legs and the anal structure.	en	Lapolla, John S., Burwell, Chris, Brady, Seán G., Miller, Douglass R.

072E8795FFC6916AFF3B3687FCA2FE53.taxon	etymology	Etymology. The generic name Acropygorthezia is a feminine noun and is a combination of the names of the attending ant, Acropyga, and the scale suffix Orthezia. The species epithet is given to honor Dr. Douglas J. Williams (Natural History Museum, London), for his numerous contributions to the systematics of mealybugs associated with ants. His works serve as the foundation of our knowledge on the mealybug aspects of the fascinating interactions between pseudococcids and ants.	en	Lapolla, John S., Burwell, Chris, Brady, Seán G., Miller, Douglass R.
