Gueriniella decorata Borchsenius

Gueriniella decorata Borchsenius, 1949: 338 .

Diagnosis. Refer to the diagnosis of Gu. serratulae . Lectotype of Gu. decorata 4.4 mm long, 2.7 mm wide.

Type data. ARMENIA: Megri , ex Verbascum , 25.v.1947 (N. Borchsenius) .

Type material. Syntypes: ad ♀, “ Gueriniella /decorata/Borchs.”//“ Verbascum / ARMENIA /Megri/ 24.v.47./ N. Borchsenius /10/74” ( BMNH) ; 2 ad ♀♀ (same data, except ‘1974’ instead of ‘74’) ( BMNH) ; additional material ( ZMAS) .

Taxonomic notes. Refer to the discussion of the genus Gueriniella for a discussion of similar species.

The World Catalogue listed only ZMAS as the type depository for this species, but we examined type

material present in the BMNH collection. We did not designate a lectotype from this material because Recommendation 74D of the ICZN (1999: 84) states that, “a lectotype should be chosen from syntypes in the collection of a public institution, preferably of the institution containing the largest number of syntypes of the nominal species-group taxon, or containing the collection upon which the author of the nominal species-group taxon worked, or containing the majority of that author’s species.” The majority of Borchsenius’ material is present in ZMAS. We were unable to examine material from that collection, so we refrain from designating a lectotype from material present in the BMNH.
