Materials examined: Holotype: ♀, USA, TX, College Station , G. H. Herrick Leg.; USNM; Type No. 13719 USNMENT 00779882 . Paratype: 9♀, same information as holotype, USNM . Other material: 11♀, AR , Hoxie, L. H. Weld Leg., Quercus lyrata, Beutenmüller Coll. rec’d 1935, USNM. 14♀, TX , Houston, L. H. Weld Leg., 4–31.III.1918. Quercus minor, Beutenmüller Coll. rec’d 1935, USNM .

Striatoandricus aciculatus was first described based on specimens reared in College Station, TX from post oak ( Quercus minor (Marshall) Sarg. = Q. stellata ) ( Beutenmüller 1909b), and have also been reported from Quercus durandii Buckley (= Quercus sinuata Walter ) and Quercus lyrata Walter ( Weld 1959) . This species fits the morphological characteristics of Striatoandricus such as the striated metasoma ( Figs. 23–25 ), and is therefore transferred herein. Similar galls have been observed on iNaturalist across multiple US states surrounding the Gulf of Mexico (e.g. on Quercus austrina Small , iNaturalist observation 94165953), but specimens are needed to confirm the true range of S. aciculatus .
