(Figs 53–55)
Holotype. Female. BRAZIL: Santa Catarina, Nova Teutonia, January 1966, F. Plaumann (MCZC, paratype of L. varius).
Paratypes. BRAZIL: Distrito Federal, Cabeca do Veado, 3600’, 14–30 October 1971, E. Munroe (1 3, PMAE); PARAGUAY: Concepcion, Estancia Don Carlos, 160m, 23°24’S 56°30’W, 16–20 December 2004, B. Garcete (1 3, MIUP).
Diagnosis. Liosphex micropterus is unique in Liosphex in showing the following character combination: IOD:LOD 1.45–1.7; relatively short wings, which are only 2.1–2.2× as long as mesosomal length and the completely dark brown or blackish metasoma. This species is similar to L. atratus but they can be differentiated by the IOD-LOD-ratio and the wing length.
Description of the female. Head (Fig. 53): Maximum width in frontal view 1.7 mm. UID 1.7× LID. Distance between eye and torulus about same width as distance between eye and mandible. Flagellomeres short (flagellomere II 2.9×, flagellomere VII 2.1× as long as wide). Apical bristles present on flagellomeres I– VI, longer bristle on flagellomere I 0.8× its length. OOD 2.2×, IOD 1.45×, MOD 1.0× LOD.
Mesosoma: Length of mesosoma: 3.0 mm. Anterior margin of pronotum without median notch (as in Fig. 20).
Wings: Maximum length of forewing: 2.1 mm, 2.1× as long as mesosoma. Forewing 1cu-a inclivous, distad M by 1.7× its length. Basal angle of 1Rs almost rectangular. Rs of hindwing reclivous.
Legs: Forebasitarsomere short, length of antennal cleaner 0.4× its length. Mid- and hindfemur with a few bristles spread over its distal dorsal area. Hindtibia with two bristles on only one side of insertion of shorter apical spur (as in Fig. 22).
Metasoma: Tergite I 1.6× as long as wide.
Color (as in Figs 54–55): Basically dark brown to black except the following: Mandibles except teeth, labrum, clypeus except median spot and most inner part of eye notch pale yellowish; tarsomeres and lateral side of fore tibia brown; ventral side of antennae and tibial spurs pale brown; wings pale brown.
Pilosity: Body, including legs, largely covered with dense setae. Setae lacking on following structures: occiput, ventrolateral side of pronotum, ventrolateral side of scutellum, median area of mesepisternum, ventral part of metepimeron, anteroventral of metepisternum, median part of lateral side of propodeum and posteroventral half of hindfemur.
Description of the male. Head, mesosoma and metasoma as in female except the following:
Head: Maximum width in frontal view 1.4–1.5 mm. UID 1.65–1.7× LID. Flagellomere II 2.2–2.45×, flagellomere VII 1.6–1.7× as long as wide. MOD 1.1–1.2× LOD.
Mesosoma: Length of mesosoma: 2.4–2.5 mm.
Wings: Maximum length of forewing: 5.2–5.5 mm, 2.2× as long as mesosoma. Forewing 1cu-a distad M by 0.9–1.6× its length. 1Rs cell 2.1× as long as high.
Legs: Tarsomeres II–IV with plantulae.
Metasoma: Tergite I 1.6× (difficult to measure in the second male but definitely lower than 1.6) as long as wide.
Life history. Almost nothing is known about the life history of Liosphex micropterus. The types were collected between mid October and January.
Etymological note. The specific epithet ‘ micropterus ’ is Greek and means ‘small wing’, referring to the relatively short forewings of this species.
Note. The type series of L. micropterus includes one specimen, which was part of the original type series of L. varius Townes, 1977.
