description: Dactuliothrips prosopis sp. n.
Female: Color dark brown (Fig. 10). Fore tibiae and tarsi lighter; fore wings light brown, pale in basal quarter and darker in the middle area around transversal veins (Fig. 81); major setae dark brown; antennae dark, but apex of segment II and segment III pale and segment IV pale with darker apex (Fig. 16).
Head (Fig. 26) about as long as wide, reticulate striate without microtrichia, cheeks slightly arched. Ocellar setae III longer than ocellar setae I and II, bases of ocellar setae III close together. Postocular setae developed, setae I and III around 3–4 times longer than the other postocular setae. Antennae with rings or annulations covered with microtrichia which are faint on segment I (Fig. 16). Antennal segments III & IV with two emergent circular sensoria at apex. Pronotum (Fig. 34) about twice as wide as long; reticulate striate with many prominent setae, four pairs on anterior margin and five longer pairs on posterior margin. Microtrichia absent on pronotum. Mesonotum reticulate striate without microtrichia (Fig. 41). Metanotum without microtrichia, with arcuate sculpture, and with one pair of setae on anterior margin (Fig. 41). Metapleura reticulate striate without microtrichia. Fore tibia with two pairs of well-developed slightly curved setae on internal anterior margin; fore femora thickened and armed with between 5–6 heavy spurs on inner anterior margin (Fig. 66). Hind tibiae with about five well-developed setae on apex. Fore wing (Fig. 81) rounded at apex with five cross veins, fore vein with between 21–24 setae, hind vein with 20–21 setae. Abdomen (Fig. 10) broad with rounded apex. Tergites with faint transverse reticulation with microtrichia laterally. Sternites without microtrichia, with 9–10 well-developed discal setae (Fig. 48); sternite VII with three pairs of posteromarginal setae and two similarly-sized or slightly smaller pairs of supernumerary setae aligned with the posteromarginal setae (Fig. 53).
Measurements: Female holotype (in microns). Total body length 1,904; head length 193, width 207; interocellar setae III 54; distance between their bases 22; postocular setae (outer) 77, (inner) 71. Pronotum length 144, width 300. Fore wings length 990, width 195. Antennal segments length (width): I, 34 (37); II, 44 (32); III, 73 (22); IV, 64 (22); V, 59 (20); VI, 60 (19); VII, 54 (17); VIII, 47 (16); IX, 55 (12).
Male: Smaller than female, and similar in color (Fig. 11). Fore femur similar to female with 3–4 heavy spurs on inner anterior margin (Figs 67, 69). Fore tibia with two developed setae on anterior margin (Fig. 69). Abdominal tergite I with paired longitudinal ridges that reach the anterior margin (Fig. 58). Abdominal sternites without discal setae, with three pairs of posteromarginal setae and microtrichia laterally (Fig. 62).
Measurements: Male paratype (in microns). Total body length 1,104; head length 149, width 151; interocellar setae III 37, distance between their bases 12; postocular setae (outer) 47, (inner) 47. Pronotum length 102, width 176. Fore wings length 675, width 110. Antennal segments length (width): I, 30 (34); II, 39 (27); III, 47 (21); IV, 44 (20); V, 39 (20); VI, 39 (17); VII, 32 (17); VIII, 27 (15); IX, 22 (12).
Material examined. Holotype female, Argentina, Mendoza, Gustavo André, on Prosopis alpataco Phil. (Fabaceae) (Figs 1–2), 05.xi.2009 (C. de Borbón), in EEA Mendoza INTA. Paratypes: 23 females, 3 males same data as holotype; 4 females, 15.xi.2009, same place, host and collector in EEA Mendoza INTA and Instituto Fundación Miguel Lillo (IFML); Uspallata, 7 females, 2 males, on Prosopis alpataco Phil. (Fabaceae), 23.ix.2002 (C. de Borbón), in EEA Mendoza INTA.
Comments. This species is closely related to kaszabi and monttea sp.n., they share the presence of fore wings with a pale area near the base and a less-developed ocellar setae III. However, it can be distinguished from kaszabi by the lack of microtrichia on the head, pronotum, metapleura, and abdominal sternites. It can be distinguished from monttea sp.n. by the absence of microtrichia in the mesonotum, metanotum, and abdominal tergite VIII. Additionally, the males have tergite I with a pair of longitudinal ridges reaching the anterior margin of the tergite (Fig. 58), in kaszabi the ridges are incomplete; and there are no claws bearing short setae on the fore tibiae as in monttea sp.n. This species was mistakenly assigned to kaszabi by de Borbón (2005). Specimens from D. prosopis sp.n. were collected in a desert plain area and in a mountainous area ranging from 1900 to 2500 masl in Mendoza, Argentina. In both localities material was collected from Prosopis alpataco Phil (Figs 1–2).
