Taxonomic notes. Argentinomyia tropandeana sp. nov. is similar to A. belmira sp. nov., A. ivani sp. nov. differing by the following combination characters: Scutum with two median pollinose white-ash vittae on anterior half beyond the notopleural suture, two additional lateral vittae beginning on line of notopleural suture, extending 3/4 of metanotum, apically acute (Figs 69B, E); wing slightly darkened in the anterior margin from the costal cell to the stigma, cells r1 and r4+5, with some small hyaline areas, microtrichose, stigma dark brown; plumula reddishbrown; halter white, capitulum whitish brown (Figs 69 B-C, E-F). Based on males, A. tropandeana sp. nov. differs from A. belmira sp. nov. and A. ivani sp. nov. in having the surstylus in ventral view (Fig. 85C) slightly parallelsides [versus surstylus concave in A. belmira sp. nov. (Fig. 17C) and A. ivani sp. nov. (Fig. 36C)] (see “diagnosis” under each species or key). Etymology. The specific epithet “ tropandeana ” (nominative, adjective feminine) is derived from the ecoregion’s name Tropical Andean where the species was found and the Latin suffix - ana denoting a place, locality, country, or belonging to, pertaining to. Biology. Label data and field observations suggest that A. tropandeana sp. nov. visits flowers of Baccharis sp., Pentacalia trianae (Asteraceae) and Bromelia sp. (Bromeliaceae). Geographical range. Argentinomyia tropandeana sp. nov. (n= 12) is distributed in both slopes of Central Cordillera in Colombia (Antioquia, Risaralda) and Cordillera Oriental Sur in Bolivia (La Paz) Ecuador (Pichincha) and Perú (Huanuco) (Fig. 91C).

(Fig. 17C)] (see “differential diagnosis” under each species or key). Etymology. The name Argentinomyia ivani sp. nov. is a patronym given in memory of the uncle of the first author, Iván Montoya (Pharmacist for more than 40 years), who after my beloved father Augusto Montoya passed away, provided me support, guidance and fruitful teachings that will remain forever in my mind and heart. For him, this beautiful species that flies high as his unforgettable smile and admirable way of being, with open hands to serve those who need it. Geographical range. Argentinomyia ivani sp. nov. (n= 1) is distributed in the Central Cordilleras in Colombia (Fig. 91A). The species is endemic to the Tropical Andes, distributed at the middle and high altitudes (3170–3200 m) in the Northern Andes domain and Magdalena province.Published as part of Montoya, Augusto L. & Wolff, Marta, 2023, Taxonomic revision of the Neotropical genus Argentinomyia Lynch-Arribálzaga, 1891 (Diptera: Syrphidae), with description of 16 new species, pp. 1-157 in Zootaxa 5234 (1) on pages 64-66, DOI: 10.11646/zootaxa.5234.1.1, http://zenodo.org/record/760999

FEMALE. Unknown. Taxonomic notes. Argentinomyia serendipia sp. nov. is similar in appearance to A. teresae sp. nov. from which it differs in the antenna black; frontal triangle dark pollinose (Figs 74A, C); terga 3 rd and 4 th with a pair of small rectangular maculae extending 1/6 of tergum length and restricted to basolateral margins of tergites (Fig 74B). In A. teresae sp. nov. the antennae brownish, orange ventrally; frontal triangle golden pollinose (Figs 79A, C); terga 3 rd and 4 th with a pair of small basolateral rectangular maculae extending 1/3 of tergum length (Fig 79B). Based on males, A. serendipia sp. nov. differs from A. teresae sp. nov. in having the surstylus in lateral view (Fig. 75A) larger than the epandrium [versus surstylus shorter than the epandrium in A. teresae sp. nov. (Fig. 80A)]; dorsal area of the apex of hypandrium (superior lobes) in lateral view (Fig. 75A) extending dorsally backward with a small sclerotized inner spur [versus no extending dorsally backward, without a small sclerotized inner spur in A. teresae sp. nov. (Fig. 80A)] (see “diagnosis” under each species or key). Etymology. The name “ serendipia ” is a noun in apposition, which comes from the English word “serendipity”: a lucky, spontaneous and unexpected discovery that happens happily or beneficially without looking for it. This name was selected based on three features. First of all, the discovery of the species was fortuitous, since it was found during the search for additional material of the new species A. teresae sp. nov. in its type locality. Second, the unique structure of the male genitalia confirmed it as a new species. Thirdly, the name also alludes to the full inspiration and positive vibes that the first author has received from a being of light. Remarks. It is highlighted that A. serendipia sp. nov. and A. teresae sp. nov. are sympatric, collected from the same type locality in the Páramo complexes Belmira, located in northwestern Tropical Andes. Geographical range. Argentinomyia serendipia sp. nov. (n= 6) is known to occur in two localities in the massif of the Central Cordillera in northwestern Colombia (Antioquia) (Fig. 91B). The species is endemic to the North Andes domain, probably confined to high‐altitude cloud Andean forests in the Magdalena province (3170–3200m) and may be abundant above 3000 m.Published as part of Montoya, Augusto L. & Wolff, Marta, 2023, Taxonomic revision of the Neotropical genus Argentinomyia Lynch-Arribálzaga, 1891 (Diptera: Syrphidae), with description of 16 new species, pp. 1-157 in Zootaxa 5234 (1) on pages 122-124, DOI: 10.11646/zootaxa.5234.1.1, http://zenodo.org/record/760999

The “ <i>Jalca</i> ” is defined in its broadest sense as the shrubby or prairie, humid or sub-humid mountain range, located between 4,800 to 6,768 meters above sea level (Height of Huascarán) (Sonter <i>et al.</i> 2018).</p> <p> <b>Taxonomic notes.</b> <i>Argentinomyia jalcaensis</i> <b>sp. nov.</b> is similar in appearance to <i>A. opaca</i>, from which it differs in having the following combination of characters: Generally metallic bluish-black. Face slightly produced; oral opening about 1.5 times as long as wide; antenna black (Figs 37A, C, D-F); scutum yellow pilose; halter black (Figs 37 B-C, E-F); legs except pro- and mesotibiae yellow on apical 1/5 and basal 1/3, yellow pilose (Figs 37A, C, DF). <i>Argentinomyia opaca</i> is characterized by the face perpendicular with a well-rounded tubercle, deeply concave dorsally (Figs 59A, C, D-F); scutum black pilose; halter white (Figs 59 B-C, E-F); legs black, black pilose (Figs 59A, C, D-F). Based on males, <i>A. jalcaensis</i> <b>sp. nov.</b> differs from <i>A. opaca</i> in having the hypandrium in ventral view (Fig. 38C) acuted laterally towards the apex [<i>versus</i> hypandrium narrowed laterally towards the apex in <i>A. opaca</i> (Fig. 60C)]; apex of hypandrium (superior lobes) no feline claw shape, with a lateral rounded extension (Fig. 38C) [<i>versus</i> apex of hypandrium feline claw shape in <i>A. opaca</i> (Fig. 60C)] (see “differential diagnosis” under each species or key).</p> <p> <b>Distribution.</b> <i>Argentinomyia jalcaensis</i> <b>sp. nov.</b> (n= 1) is exclusively distributed in the highlands (4100 m) of the Cordillera Occidental and Central Sur in Perú, which corresponds to the Central Andes domain, Puna province (Fig. 91C). The species is restricted to high-elevation Jalca grassland of Cerro Cahuish in Perú, which raises the need for further expeditions to neighboring areas of the type locality, in order to discover and describe the female specimens as well as to know its population dynamic and conservation status.</p> <p> <b>Conservation status.</b> Unfortunately, the region where <i>A. jalcaensis</i> <b>sp. nov.</b> inhabits is near the Pierina gold and silver open-pit mine, located in the Callejón de Huaylas in the Peruvian Andes (Cordillera Negra of northcentral Perú), approximately 10 kilometers directly north of Huaraz at a height of 4100 meters. Since mining has the potential to produce serious and specific threats to biodiversity, with intensive land use that severely fragments and declines the extension and quality of the habitat due to deforestation (see Sonter <i>et al.</i> 2018; Montoya <i>et al.</i> 2021), with the loss of connectivity by the reduction of functional conservation corridors, we consider that populations of <i>A. jalcaensis</i> <b>sp. nov.</b> is probably “Near Threatened”, “Endangered” or “Vulnerable”, since it occupies small range, threatened by several human threats. In this sense, we suggest that this species should be studied and its level of threat evaluated, taking into account the conservation criteria of the International Union for Conservation for Nature—IUCN, considering the restricted distribution to a unique habitat such as the Jalca, where the impact of gold and silver mining could cause its disappearance in the coming years, making the need to encourage conservation efforts as has suggested for species <i>Copestylum enriquei</i> Montoya, Parada-Marín & Ramos-Pastrana, 2022 in the Amazonian region (Montoya <i>et al</i> 2022).</p>Published as part of <i>Montoya, Augusto L. & Wolff, Marta, 2023, Taxonomic revision of the Neotropical genus Argentinomyia Lynch-Arribálzaga, 1891 (Diptera: Syrphidae), with description of 16 new species, pp. 1-157 in Zootaxa 5234 (1)</i> on pages 66-68, DOI: 10.11646/zootaxa.5234.1.1, <a href="http://zenodo.org/record/7609993">http://zenodo.org/record/7609993</a>
