Claws fairly long and narrow, much longer than width of tarsus; claw digitules spinose or setose, shorter than claw; a small claw denticle almost always present.

Abdomen: Segments I–VII: tergites lightly sclerotized; sternites also lightly sclerotized but with distinct, sclerotized, intersegmental ridges. Presence of loculate pores and their distribution varies across genera. Tubular ducts present in a band across tergite VII (or on two separate plates in Praelongorthezia), inner surface of each duct with shallow spiral ridges. Abdominal spiracles present on anterodorsal part of pleurites I–VIII at least but more or less easily detectable. Segment VIII: tergite unsclerotized; sternite lightly sclerotized but with a strongly sclerotized crescentic ridge along anterior and lateral margins, fusing with sclerotization of penial sheath posteriorly; tergite with hs dorsal abdominal setae, plus locular pores (absent in Newsteadia), structurally different from lp on other abdominal segments (slightly smaller with an external ring divided in many small compartments, and without an inner large loculus; see Discussion) and many smp; pleural hs present.; sternite with ventral abdominal setae but no pores; sometimes with a median ridge. Genital segment: Segment IX represented by area immediately around anus on dorsal surface, represented by a sclerotized area in anal region; hs present on tergite IX; anus large with a lightly sclerotized area along anterior margin; sternite IX represented by a large sclerotized sternal plate (except for Newsteadia), presence of a median ridge and/or setae variable across genera. Penial sheath broad, triangular, and blunt; ventrally and laterally with a group of short, apically rounded setae on each side of anterior end of penial sheath; posteriorly, minute setae absent on either surface near apex. Aedeagus parallel sided anteriorly but becoming pointed posteriorly in dorsal view (apex broader in Newsteadia), extending to near apex of penial sheath. Penial sheath with a small group of sensilla near apex.

Comments: The wing venation for this family description includes the presence of only subcostal ridge, cubital ridges, and anterior flexing patch (the latter absent in Newsteadia). Koteja (1986) described the wings of Orthezia urticae and identified an anterior flexing patch (= “medial sector” in Koteja, 1986) and a radial sector (see current terminology in Koteja, 2008). Wing venation in Coccoidea, especially for the flexing patches and radial sector are challenging to observe on slide-mounted specimen, principally due to clearing with KOH (Koteja, 2008) and are best observed on fresh or dry unmounted material (Simon, 2013). The radial sector could not be identified on studied mounted material, but may be present.

Comments: Because Graminorthezia currently comprises 11 described species (Miller et al., 2013) based on female morphology, the description of the adult male of G. graminis acts for now as the generic diagnosis. The genus is classified in the tribe Ortheziini (Kozár, 2004), along with Insignorthezia, Orthezia, and Praelongorthezia, and was defined based on adult female morphology and distinguished from these other genera by “bands or rows of wax plates within the ovisac band,” “head of dorsum without sclerotized cephalic plates,” and “no more than 7 abdominal spiracles” (Kozár, 2004: 271). The genus is distributed mainly in the Nearctic, with some species in the Neotropical regions.

Dorsal abdominal setae and pores (totals): segments I–V 4 hs; VI 4 hs; VII about 20 hs and between 24 and 35 tubular ducts, in a band with about 3 rows of ducts.

Comments: Most of the structures were observable on these two uncleared specimens apart from some pores and setae on the thorax and the abdominal sternites. Some setae could be identified by their basal sockets, which are visible with confocal images. However, loculate pores (lp) were mostly not identifiable, and so mentioned as “not observable/ detected” in the description; minute simple pores could not be detected with confocal images. Despite these missing details, it is clear that Graminorthezia is distinguishable from Orthezia based on male morphology. The distinctive characters are the general shape of the setae covering the body and appendages, which were distinctly blunt apically (fig. 2A); the shorter appendages than on the other species studied, and the larger and fewer ommatidia (i.e., about 60) in each compound eye.

Comments: Because Insignorthezia comprises 10 described species (Kozár, 2004), the description of the adult male of I. insignis acts for now as the generic diagnosis. Adult female Insignorthezia are distinguished from Graminorthezia, Praelongorthezia and Orthezia by the “absence of bands or rows of wax plates within the ovisac band” (Kozár, 2004: 271).

Generic Diagnosis, based on adult male morphology: Head with dorsal midcranial ridge strong but fading posteriorly; ventral midcranial ridge strong and bifurcating posteriorly, compound eyes each with 30–50 ommatidia (vs. >60 and usually >100 in other genera); prosternum with a triangular sclerotized area (vs. prosternai medial ridge in other genera), with well-sclerotized margins; scutellum without setae or pores but with smp; scutum with median area short, without hs near lateral margins; metathorax with metatergal setae and pores present, but without smp; wing shape rounded, with reduced venation compared to other Ortheziidae (subcostal and cubital ridges only present); alar lobe or fold absent; hamulohalteres absent (vs. present in Orthezia, Praelongorthezia, Insignorthezia, and Graminorthezia); legs with long hs; abdominal tergite VIII without locular pores (vs. present other known genera); sternite VIII without pores or setae; apex of aedeagus widening at tip (vs. pointed in other known genera); sternite IX undiscernible from penial sheath (see Discussion), body completely lacking of lp (vs. present in all other known genera).

Comments: The specimen studied here is particularly large, generally more sclerotized and with a larger number of loculate pores compared to other Ortheziidae. Additionally, the body is covered with small sclerotized dermal structures, different from any small pores. Finally, the aedeagus shape differs from other genera, tapering at midlength and becoming pointed apically. However, this might be an artifact of slide-mount preparation.

Comments: Because Praelongorthezia currently comprises 23 described species based on female morphology, the description of the adult male of P. praelonga acts for now as the generic diagnosis. The genus is classified in the tribe Ortheziini (Kozár, 2004) with Insignorthezia, Graminorthezia, and Orthezia. Praelongorthezia was defined based on adult female morphology and distinguished from these other genera by “bands or rows of wax plates within ovisac” and “head of dorsum with sclerotized cephalic plates” (Kozár, 2004: 271). Praelongorthezia has a Neartic and Neotropical distribution.

Comments: This single specimen was assigned to Orthezia ?graminicola based on an adult female with different collection information. This specimen, however, displays several unusual features not found in Orthezia species, namely: (1) very few tubular ducts on tergite VII, with very short setae (2) locular pores completely absent on both tergites and sternites, which also have very few setae; (3) legs with notably few setae, and (4) antennae with long capitate setae, a character not previously observed in Ortheziidae.
