Psyllobora vigintimaculata ( Say, 1824) .

Swezey (1925: 374) noted the failed introduction of Psyllobora taedata LeConte for California in 1896 for the control of Oidium . No further record of this species appears in Hawaiian literature until Nishida (2002) listed it as purposely introduced but not established. Brenner (2010) and Tavares et al. (2013) reported collections on Maui and Oahu respectively.

Justification: ITIS lists P. vigintimaculata (TNS: 692589) and cites Gordon (1985). Gordon (1985: 857) justified the name Psyllobora vigintimaculata (Say) stating “ Psyllobora taedata has been considered a synonym or variety of P. vigintimaculata by some previous authors, and most recently, Timberlake (1943) regarded P. taedata as a valid species. I consider P. taedata a junior synonym of P. vigintimaculata because the morphological differences between the eastern and western population are gradually clinal and it is impossible to delimit well

characterized geographic races.” Gordon (1985: 855-858) provided the following synonyms of Psyllobora vigintimaculata (Say) :

Coccinella 20-maculata Say 1824: 96. Psyllobora viginti-maculata: Mulsant 1850: 183 ; Mulsant 1866: 137; Crotch 1874: 141; Gorham 1892: 167 (in part); Timberlake 1943: 42.

Names Used in Hawaii: Leeper (1976: 280) did not list this species. However, since that date, the species Psyllobora vigintimaculata (Say) can be found in Hawaiian literature as:

Psyllobora taedata LeConte ; Nishida 2002: 52.

Psyllobora taedata LeConto ; misspelling, Brenner 2010: 22.

Psyllobora viginti taedata ; Tavares et al. 2013: 3.

The UHIM currently does not list the species within their collection. Three specimens were donated to the museum by Jane Tavares in April, 2014, labeled as P. viginti taedata .

This is the first use of Psyllobora vigintimaculata (Say) in the Hawaiian literature.
