Remarks
- Systematics: Subfamily DIASPIDINAE Tribe DIASPIDINI Subtribe CHIONASPIDINA (Normark, et al., 2019)
Normark, et al., 2019 determined that Unaspis is a monophyletic genus.
Lepidosaphes Shimer, 1868 is similar to Unaspis in body features, but differs by having a pair of gland spines between the median lobes that are absent in Unaspis (Niu & Feng, 2019). Takagi (2024) suggests that the female tests of Unaspis females are formed mainly by back-and-forth movements of the abdomen, representing an effective way in test-formation. He contrasted this with the elaborate test construction observed by Matsuda (1927) in the circular test of the Aspidiotine scale insects.
- Structure: Female scale brownish, elongate, usually with a median longitudinal ridge; exuviae terminal. Male scale white, felted, elongate. The important characters are 2-barred ducts; dorsal ducts numerous on pygidium posteriorly to eighth (median lobe) segment; 3 pairs of lobes present, the median lobes not zygotic, the 2nd and 3rd lobes bilobed. Gland spines absent from between median lobes but present laterally. Perivulvar pores present or absent (Williams & Watson, 1988).
- General Remarks: Detailed descriptions by Balachowsky (1954e) and Williams & Watson (1988).
