Simple multilocular pores (Fig. 3 G), each 10–12 µm in diameter, with bilocular centre and 8–10 outer loculi, scattered on margin to submargin of head and thorax and across abdomen. Multilocular pores (Fig. 3 B, C), each 10–12 µm in diameter, with bilocular or trilocular centre and 3–8 outer loculi, appearing slightly bluish when stained, scattered medially to submedially on head and thorax; similar pores (Fig. 3 I), each 12–13 µm in diameter, with bilocular centre and 6–10 outer loculi, scattered within marsupium. Elongate tubercles present in marginal longitudinal band; each tubercle with simple multilocular pores, similar to pores on derm, and robust hair-like setae on tips, 105–325 µm long.

Venter. Pore shape and distribution as for genus. Hair-like setae (Fig. 4 A) 35–95 µm long on most segments; a single pair of long hair-like setae 350–425 µm long at abdominal apex. Flagellate setae 18–23 µm long, distributed as for genus. Multilocular pores (Fig. 4 B) each 5–6 µm in diameter on all body segments.
Type data. MEXICO, Baja California, Montevideo Canyon near Bahia de Los Angeles, ex Bursera microphylla, 31.xii.2004 (C.M. Unruh).
Type material. Holotype: ad Ψ, data as above (BME). Paratypes: 4 ad ΨΨ (ad Ψ missing two legs= CMU 121), dozens of first-instar nymphs (6 slides), data as above (BME).
Etymology. The specific name is derived from the host plant from which the insects were collected and is a noun in apposition.
Taxonomic notes. This species was collected while the author was on a field trip with the UC Davis Botany Club during a very wet December in 2004. The group was “botanizing” around the Montevideo wall paintings campground located 15 km northeast of Bahia de Los Angeles. We climbed to the top of the cliff overhanging the wall paintings and a fellow U.C. Davis graduate student, Shelah Morita, discovered adult females of this species while examining a small elephant tree (Bursera microphylla). The group crowded around the plant to get a good look at a scale insect and the author took photographs and collected several specimens.
First-instar nymphs were not visible on the stems of the plant, but were present in the marsupium of the adult female and were extracted during the slide-mounting process.
Diagnostic comparison. This species most closely resembles C. tuberculata and is here placed in the C. mexicana species group. The first-instar nymphal stage of C. bursera differs from all other known iceryine species by the presence of very stout robust setae on the margin and submarginal dorsum. The adult females of C. bursera and C. tuberculata can be separated by the size of the tubercles (C. bursera has much larger tubercles), the density of short hair-like setae surrounding the marsupial band (C. bursera has dense rows of setae outside the marsupial band), and the shape and distribution of the multilocular pores on the derm (C. bursera has multilocular pores, each with a bilocular centre and 10–12 outer loculi, that do not seem to form any distinctive arrangement and do not form marginal clusters).
