Type species. Lautaroderus malalcahuello sp. n., by present designation and monotypy.
Diagnosis (female). Calcar short and bifid ( Fig. 3D View FIGURE 3 ); tarsi of all legs 4-segmented ( Figs 3C‒F View FIGURE 3 ); flagellum 9-segmented, with first anellus ( Fig. 2E View FIGURE 2 : an1) tiny, ring-like, and second anellus ( Fig. 2E View FIGURE 2 : an2) larger, funicle 4- segmented, and club 3-segmented; face with X-shaped pattern of grooves ( Figs 2B View FIGURE 2 , 3G View FIGURE 3 ); clypeus delimited by sutures dorsally between tentorial pits and laterally, its anterior margin incurved ( Figs 2B–E View FIGURE 2 ); occipital carina absent ( Fig. 2A View FIGURE 2 ); mesothoracic spiracle exposed ( Figs 3A, G View FIGURE 3 ); propleura diverging posteriorly ( Fig. 3A View FIGURE 3 : pl 1); prepectus large ( Fig. 3C View FIGURE 3 : pp); mesoscutum with anterior one-half of midlobe and lateral parts of sidelobes with scattered bristles, and notauli sulcate anteriorly but shallower, slightly fading posteriorly ( Fig. 2A View FIGURE 2 ); mesoscutellum with two pairs of setae ( Fig. 2A View FIGURE 2 ); metascutellum ( Fig. 2A View FIGURE 2 : mtsc) wide and triangular, about one-third as long as mesoscutellum; fore wing ( Figs 1A–C View FIGURE 1 ) with basal cell densely setose, speculum absent, basal vein present as a pigmented fold, subcosta of SMV broken at junction with parastigma, and PMV and STV long, of about same length; hind wing with distinct spur vein in shape of a sclerotized process ( Figs 1A–C View FIGURE 1 ); gaster with Gt 1 not swollen, Gt 7 present as syntergum ( Fig. 3B View FIGURE 3 ).
Description. Face with distinct tentorial pits ( Figs 2D, E View FIGURE 2 ); clypeus delimited by sutures, its anterior margin incurved ( Figs 2B–E View FIGURE 2 ); facial grooves X-shaped ( Figs 2B View FIGURE 2 , 3G View FIGURE 3 ), the scrobal grooves disconnected and transfacial sulcus very short ( Fig. 3G View FIGURE 3 : sg), with arms of frontal sulcus V-shaped ( Figs 2B View FIGURE 2 , 3G View FIGURE 3 : fs) and extending toward posterior ocellus but ending between compound eye and median ocellus ( Fig. 3G View FIGURE 3 : fs). Flagellum with second anellus 1.5× smaller than any of F1–F4; club 3-segmented ( Figs 2D, E View FIGURE 2 ). Malar sulcus present ( Figs 2B–E View FIGURE 2 ). Mandible bidentate, with two equal acute teeth and with exposed and visible muscle, which extends into broad incision ( Fig. 2C View FIGURE 2 ). Occiput not margined, evenly curved, without occipital carina ( Fig. 2A View FIGURE 2 ). Pronotum relatively wide, its collar with about 10 bristles and with isolated large bristle on each posterolateral corner, its collum short, evenly sloping, with sparse, short setae ( Fig. 2A View FIGURE 2 ). Propleura diverging posteriorly, prosternum with sulcate discrimen medially ( Fig. 3A View FIGURE 3 ). Mesothoracic spiracle exposed ( Fig. 3A View FIGURE 3 : msp). Prepectus ( Fig. 3C View FIGURE 3 : pp) large, over 10× longer dorsally than narrow acropleuron ( Fig. 3C View FIGURE 3 : ar), and about as wide as lateral panel of pronotum ( Fig. 3A View FIGURE 3 ). Mesoscutum with numerous short setae anteriorly and on sidelobes; notauli sulcate anteriorly but shallower, slightly fading posteriorly; posterior part of midlobe with two pairs of long bristles and some smaller setae between them ( Fig. 2A View FIGURE 2 ). Mesoscutellum with two pairs of strong bristles ( Fig. 2A View FIGURE 2 ), frenal area not marked off ( Figs 1D, E View FIGURE 1 , 2A View FIGURE 2 ). Mesopleuron with distinct femoral depression and straight transepimeral suture ( Fig. 3A View FIGURE 3 ). Metascutellum ( Fig. 2A View FIGURE 2 : mtsc) wide and triangular, about 1/3 as long as mesoscutellum, lateral panels of metanotum as wide as metascutellum ( Figs 1D, E View FIGURE 1 , 2A View FIGURE 2 ). Propodeum with wide median carina fading posteriorly ( Fig. 1E View FIGURE 1 ); propodeal spiracle small and round, separated from metanotal margin by about its own diameter ( Figs 1D, E View FIGURE 1 : psp). Legs with 4-segmented tarsi ( Figs 3C–F View FIGURE 3 ); fore leg with short, nearly straight, bifid calcar ( Fig. 3D View FIGURE 3 : ca) and longitudinal basitarsal comb ( Fig. 3D View FIGURE 3 : bc); mid and hind legs with spurs simple, needle-like ( Figs 3C, E, F View FIGURE 3 ). Fore wing ( Figs 1A–C View FIGURE 1 ) with basal cell densely setose dorsally and ventrally; fore wing disc without speculum; SMV broken, with subcosta abruptly joining parastigma; basal vein traceable as a dark fold; PMV about as long as STV, both elongate; fore wing disc densely setose, with setae not arranged in rows. Hind wing with distinct spur vein ( Fig. 1A View FIGURE 1 ). Petiole short, transverse. Gaster ovate ( Figs 1C View FIGURE 1 , 3B View FIGURE 3 ) with posterior margins of tergites straight ( Fig. 1B View FIGURE 1 ); Gt 1 not swollen compared to following tergites ( Fig. 3B View FIGURE 3 ); Gt 7 present as syntergum, short, with membranous apical tip; ovipositor sheaths short, ovipositor comparatively robust ( Fig. 3B View FIGURE 3 ); hypopygium not reaching apex of metasoma, mucro short ( Fig. 3B View FIGURE 3 ).
