Liriomyza archboldi Frost, 1962: 51 View in CoL ; Spencer 1983: 55; Spencer & Steigmaier 1973: 97; Spencer & Steyskal 1986; Spencer 1990: 317; Martinez & Étienne 2002: 34.

Material examined. Costa Rica. Prov. San José. Moravia. Zurquí de Moravia, Tower path. 1600m. 1-7 JUN 2013. Proyecto ZADBI . Malaise trap #1, ZADBI-810. -84:00:57 10:02:58 #106920. INB0004449118 (1M: MNCR); same except 30 MAR-6 ABR 2013, ZADBI 647 ; #106495. INB0004424654 (1M: MNCR).

Comments. The two specimens from Zurquí correspond to the original description of the species except for having both vti and vte on dark background ( Fig. 31 View FIGURES 31-34 ) (as opposed to vti on yellow and vte on black). The distinct pubescence of the first flagellomere of this species is characteristic ( Fig. 31 View FIGURES 31-34 ). The mention of this species in Spencer 1963 was a mistake and represents L. trifolii (Spencer & Stegmaier 1973) . This species was overlooked in Spencer’s 1967 catalog. It is considered an uncommon species (Spencer 1983), and is so far known from the Bahamas, Florida and Costa Rica. In Costa Rica it was previously reported from low elevation, in San José (Spencer 1983). Its host plant ( Bidens pilosa L.) is native to South America but is now cosmopolitan in distribution. It is considered an invasive weed and can grow in many different habitats and up to 3,200 m of elevation (GISD 2022).

Host plant. Bidens pilosa L. ( Asteraceae ) (Spencer & Stegmaier 1973; Spencer 1990).

Distribution. USA (Florida), Bahamas, Costa Rica ( Fig. 53 View FIGURE 53 ).
