147587B5FFE7FFFFFF14FF5A2A79FA1A.taxon	discussion	Comments. Agromyza fusca Spencer is a distinctive Agromyza species with brown halter and partially infuscated wing (Figs. 9, 10), that is now widespread in the Neotropical Region. The species was originally described from Brazil (Spencer 1963) and later found to occur in Dominica (Spencer & Stegmaier 1973), Guadeloupe (Étienne & Martinez 2003), Argentina and Costa Rica (Boucher, 2010), and reported here for the first time in Venezuela. The specimens examined differ slightly from the original description in Spencer (1963) where A. fusca is described as entirely black. Most of the specimens examined from Costa Rica and elsewhere (Argentina, Venezuela), have the first flagellomere yellow to yellowish-brown, except one female specimen from Monteverde cloud forest (Costa Rica) with entirely brown antennae. In the original description, the colour of the first flagellomere is not specifically mentioned. Unfortunately, the holotype at the National History Museum, London (BMNH) is now missing its head (image of habitus available on the BMNH website: (https: // data. nhm. ac. uk / dataset / collection-specimens / resource / 05 ff 2255 - c 38 a- 40 c 9 - b 657 - 4 ccb 55 ab 2 feb / record / 4149691). Also, the male phallus of the specimens examined has a pale ventral membranous structure, ending in a tubule, better seen in lateral view (Fig. 11, arrow), a character that may have been overlooked in the original description and in the illustration found in Spencer & Stegmaier (1973). This membranous structure is not visible in the holotype (Fig. 16), although a lateral view is not available on the BMNH website (genitalia is fixed in ventral view on a permanent mount). The ejaculatory apodeme of this species has never been described but it is distinctive due to its elongated foot and narrow blade (Fig. 13, 15). This species was collected only at the main site (Zurquí), and only from Malaise trap # 1, from March 30 th to July 5 th.	en	Boucher, Stéphanie, Borkent, Art, Brown, Brian V.

147587B5FFE7FFFCFF14F9C92D9AFE37.taxon	discussion	Comments. This species was previously known from the Caribbean Region. Although possible mines on Elephantopus elatus Bertol in Florida (Spencer & Stegmaier 1973) and mines on E. mollis (H. B. K.) in Venezuela (Spencer 1973 b) may represent this species (Spencer et al. 1992). Calycomyza dominicensis can be distinguished from other Neotropical Calycomyza by its size (2.2 mm in male to 2.5 mm in female), presence of three dc (3 rd dc much reduced), fronto-orbital plate slightly darkened to upper ors and by the distinctive well sclerotized phallus, with a pair of distinct tubular extensions, extending beyond the margin of the distiphallus in lateral view (Fig. 17). The specimens examined correspond to the original description except the male specimen is a little larger, with a wing length of 2.4 mm, and females are smaller with a wing length from 2.0 to 2. 3 mm. The epandrium and surstyli with multiple spines (Fig. 19), and ejaculatory apodeme with large stalk and blade slightly expanded (Fig. 18) are for the first time illustrated. This species was only collected at Las Alturas.	en	Boucher, Stéphanie, Borkent, Art, Brown, Brian V. (2025): The leaf-miner flies (Diptera: Agromyzidae) of Costa Rican cloud forests.

147587B5FFE4FFFCFF14FDA52F33FA59.taxon	discussion	Comments. This species was originally described from Costa Rica and later found in many Neotropical countries. Its yellow antennae (Fig. 20) differentiate this species from most other Neotropical Calycomyza, except C. punctata Sasakawa (1992 d) from Peru, but this later species has completely yellow fronto-orbital plate (black in C. meridiana). Spencer (1963) mentioned that the notopleural area of C. meridiana appears brownish, but later described as being yellow (Spencer 1973 b; Sasakawa 2005), as it is in the specimens examined (Fig. 20). The ejaculatory apodeme of this species was never illustrated before. It has a short and wide stalk with the blade only slightly wider than its base (Fig. 24).	en	Boucher, Stéphanie, Borkent, Art, Brown, Brian V.

147587B5FFE4FFFDFF14FA0E2FC8FDFF.taxon	discussion	Comments. This specimen from Tapantí was identified as C. (Diz.) scirpioides Zlobin in the list of species / morphospecies in Borkent et al. (2018), a species previously described from high elevation (2,500 m) in western Mexico (near El Salto, Durango), but it is now considered a new species (formal description will be done elsewhere). The species differs from C. (Diz.) scirpioides (Zlobin 1997) by its smaller size (2.6 mm in male not 3.0 mm), fronto-orbital plate yellowish (not blackish); calypter and fringe brown (not yellowish-white), and slight differences in the phallus, including the shorter curvature at the base of the distiphallus and the small apical enlargement of the mesophallus (arrow, Fig. 26). The study of the Cerodontha specimens from Tapantí, has brought my attention to previous specimens that were (temporarily) identified as C (D.) scirpioides in Boucher 2005. These specimens were from Cartago (1,400 m) (Costa Rica) (1 male, LEMQ) (with the distiphallus much less dilated), and San Cristobal, Chiapas (7000 ’ = 2,133 m) (Mexico) (1 female, CNC). But it is now becoming clearer that these specimens represent a new species. C. scirpioides from Durango (Mexico) (Zlobin 1997), along with the specimens examined from Tapantí (Costa Rica), Cartago (Costa Rica), and Chiapas (Mexico) have in common a reduced lower ors (Fig. 25, arrow), a character rarely observed in Agromyzidae, but also observed in C. (Diz.) ZABDI- 4 (Table 1) and in C. (Diz.) impatientis Sasakawa. The latter species was collected from Parque National Henri Pittier, Rancho Grande, Venezuela (Sasakawa 1992 d) but described from a female specimen only (and without any figures). Parque National Henri Pittier is home to a well-known cloud forest in South America (Sanchez & Liria 2009) and it is plausible that Cerodontha (Diz.) scirpioides, C. (Diz.) impatientis, the two species of Cerodontha (Dizygomyza) from ZADBI and the species (wrongly) identified as C. (Diz.) scirpioides in Boucher (2005) represent closely related species that are restricted to mid and high elevation Neotropical cloud forests.	en	Boucher, Stéphanie, Borkent, Art, Brown, Brian V.

The Zurquí specimens agree externally with the original description of the species. J. sasakawai is a black species without any metallic reflection. The male genitalia appear to show slight variation including a few more spines on the surstyli (Fig. 28) (apparently 7 not 5) and a slightly bent apex of distiphallus (Fig. 29).

147587B5FFE5FFFDFF14FAF22D54F86B.taxon	discussion	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) (as opposed to vti on yellow and vte on black). The distinct pubescence of the first flagellomere of this species is characteristic (Fig. 31). 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).	en	Boucher, Stéphanie, Borkent, Art, Brown, Brian V.

147587B5FFE2FFFAFF14FF582FC8FBBF.taxon	discussion	Comments. The specimens from Zurquí were identified as Liriomyza commelinae in Borkent et al. (2018), but it is now considered a new species. L. commelinae is a widespread Neotropical species, also found in Florida (central and southern counties), and is easily recognized by the characteristic enlarged first flagellomere in male, a character rarely seen in Liriomyza, but also occurring in L. robustae, a species described from the western Andes in Colombia (Spencer, 1984). L. commelinae also has a characteristic yellow colouration at the posterior end of the mesonotum. These two characters are identical in the Zurquí specimens (Figs. 35, 36). The abdomen of L. commelinae has been described as blackish centrally but variably yellow laterally in Spencer and Steyskal (1986), but the Zurquí specimens have a characteristic yellow first tergite, extending posteriorly into a point (Fig. 36). The phallus of L. commelinae has been illustrated by various authors (Spencer 1963, Spencer 1973 b; Valladares 1984; Pallacios-Torres et al. 2005) with some important variations between them, which could bring confusion. The phallus illustrated in Valladares (1984) and in Palacios-Torres et al. (2015) has long membranous tubules. These may have been overlooked in ventral view illustrations of Spencer (1963) and Spencer & Stegmaier (1973). The phallus of the Zurquí specimen has a few unique characteristics including a little triangular sclerite at the base of the distiphallus (Fig. 37, arrow), wider tubules with the distal end slightly enlarged, and a distinct curvature in the phallus in lateral view (Fig. 38) (straight in L. commelinae). These differences are important and justify the status of a new species. The epandrium and surstylus of the male Zurquí specimen are illustrated in Fig. 39 but has never been illustrated for L. commelinae for comparison.	en	Boucher, Stéphanie, Borkent, Art, Brown, Brian V.

147587B5FFE2FFFAFF14FF582FC8FBBF.taxon	biology_ecology	Host plant. Both L. commelinae and L. robusta feed on Commelinaceae These two Liriomyza species with enlarged first flagellomere in the male are considered sister species (Spencer 1990). It is likely that this very similar new species of Liriomyza from Zurquí also feed on a host plant in this family.	en	Boucher, Stéphanie, Borkent, Art, Brown, Brian V.

147587B5FFE2FFFAFF14FB2D2D54F848.taxon	discussion	Comments. Melanagromyza wedeliae was originally described from southern Florida and later found in Colombia and Brazil. This species is characterized by having a narrow gena, orbital setulae in two rows (inner row proclinate and outer row reclinate), eye pilose in male with a patch of white hairs at level of ors and the abdomen with a metallic green reflection. The specimen from Zurquí agrees with the external characteristic of the species. The genitalia is also characteristic with the distiphallus in the form of a short and broad tubule, slightly upcurved (Fig. 40) and a greatly elongated hypandrial apodeme (Fig. 42), not previously illustrated. The ejaculatory apodeme was not described previously but it has no (or short) stalk and the blade is rounded with irregular margin (Fig. 41)	en	Boucher, Stéphanie, Borkent, Art, Brown, Brian V.
