Grettenberger, from Bagrada hilaris foliar sentinel eggs [1 ♀, USNM, molecular voucher USNMENT918558_214413927].
Updated diagnosis. FEMALE. As described and illustrated for O. lucidus in Triapitsyn et al. (2020) except as follows: antenna with scape minus radicle 5.7–8.8× as long as wide; first funicular segment 1.5–2.0× as long as wide and 0.5–0.6× length of pedicel.
MALE. As described and illustrated for O. lucidus in Triapitsyn et al. (2020).
Distribution. Nearctic region: USA: Arizona (new record), California (Girault 1917; Triapitsyn et al. 2020 [as O. lucidus]), Texas (Noyes 2010; Triapitsyn et al. 2020 [as O. lucidus]), and Washington (Johansen 1957; Peck 1963; Noyes 2010); Neotropical region: Costa Rica (Noyes 2010).
Hosts. Confirmed and otherwise more or less trustworthy records of O. californicus are from eggs of Hemiptera: Anasa tristis (De Geer) (Coreidae) (Peck 1963; Noyes 2010), Bagrada hilaris (Burmeister) (Triapitsyn et al. 2020 [for O. lucidus]), Chinavia hilaris (Say) (Triapitsyn et al. 2020 [for O. lucidus]), Chlorochroa sayi (Stål) (Noyes 2010; Triapitsyn et al. 2020 [for O. lucidus]), and Nezara viridula (L.) (Ehler 2002; Noyes 2010) (Pentatomidae), as well as from unidentified bug eggs (Girault 1917).
Biology. Life history traits of O. californicus (as O. lucidus) were reported by Ganjisaffar & Perring (2020).
Remarks. The ITS2 sequences of specimens PR20-465 and PR20-560 of O. californicus from Tuolumne County in California, collected on Pinus sabiniana (GenBank accessions MW804270 and MW804271, respectively), were 100% identical to that of the specimen PR20-561 from Arizona (GenBank accession MW804272) and also to those of the O. lucidus paratypes (UCRC ENT 311756, 311757, 311769, and 311770) which are molecular vouchers from the study by Triapitsyn et al. (2020) (GenBank accessions MN947512 –515). Together with a maximum divergence of 0.8% in the COI sequences among specimens PR20-465, PR20-560, PR20-561 (GenBank accessions MW804625 –627) and the paratypes of O. lucidus (GenBank accessions MN935769 –772), this is a very strong indication of conspecificity. Specimen USN- MENT918558_214413927 from Davis, California, also was genetically identical to O. lucidus (S.A. Andreason, personal communication).
