description: Key to Genera of Neanastatinae 1 Acropleuron differentiated by uniformly developed crenulate sulcus curved to anterodorsal margin of pleuron near apex of prepectus (Figs 51, 60: acs); pronotum strongly transverse in dorsal view (Figs 49, 59: no 1) and almost vertical in lateral view (Figs 51, 60: no 1) [extinct]....................................... <b>2</b> − Acropleuron differentiated by linear sulcus extended anteriorly to level at least in line with apex of tegula where obliterate (Figs 22, 24: acs) or extended dorsally as less distinct, posteriorly curved furrow or line to anterodorsal margin of pleuron near middle of prepectus (Fig. 41: acs); pronotum elongatesubtriangular in dorsal view (Figs 1–4, 27, 39: no 1) and with extensive dorsal surface in lateral view (Figs 19, 21) [extinct or extant]................................ <b>3</b> 2(1) Head with occipital carina (Fig. 59: oc); axillae distinguished from scutellum by linear scutoscutellar sutures (Fig. 59: sss) and with inner angles separated by distance equal to about half own width; scutellum not carinate laterally (Fig. 59); fore wing with bare band separated from parastigma by setal region about equal in width to bare band (Fig. 62: spc); mesoscutum undifferentiated, lacking parapsidal ridges (Fig. 59)................... <b> <i>Neanaperiallus</i> gen. n.</b> − Head without occipital carina; axillae distinguished from scutellum by crenulate scutoscutellar sutures (Fig. 49: sss) and with contiguous inner angles; scutellum with carina extending along side from apex of axilla (Fig. 49: scc); fore wing with bare band contiguous with parastigma (Fig. 50: spc); mesoscutum differentiated into median and lateral regions by longitudinal, posteriorly ridged parapsidal lines (Figs 49, 51: psr)............... <b> <i>Aspidopleura</i> gen. n.</b> 3(1) Scutellum divided mediolongitudinally (Figs 4, 17, 18); axillae with inner angles separated by at least twice own width (Figs 4, 17); head lenticular with vertex and temples carinately margined relative to occiput; fore wing with linea calva extending to base of wing along anal margin (Fig. 7: lc); flagellum with basal segment ring-like and with 5 distinct funicular segments................................................................................................. <b> <i>Neanastatus</i> Girault</b> − Scutellum undivided (Figs 1–3); axillae with inner angles contiguous (Figs 2, 3, 13, 15) or at most separated by distance about equal to own width (Figs 1, 11); head ovoid with vertex and temples smoothly rounded into occiput or only vertex carinately margined (Fig. 23); fore wing either entirely setose or with linea calva (Fig. 6: lc) extending only to basal cell; flagellum with or without differentiated ring segment, but with 7 or 8 distinct funicular segments.................................................................................... <b>4</b> 4(3) Head and mesosoma patterned and at least partly yellowish to brown even if with some metallic luster (Fig. 1); scutellar-axillar complex with slightly divergent longitudinal grooves differentiating broadly separated quadrangular axillae on either side of anteriorly truncate scutellum (Figs 1, 11, 12); metanotum, propodeum and petiole all large and conspicuous regions posterior to scutellum (Figs 1, 11, 12); flagellum with 7 funicular segments............................................................................................... <b> <i>Eopelma</i> Gibson</b> − Head and mesosoma uniformly dark with variably distinct metallic luster (Figs 2, 3); scutellar-axillar complex with strongly divergent grooves differentiating triangular axillae on either side of anteriorly angulate scutellum (Figs 2, 3, 13, 15, 40); metanotum medially concealed or overlain by apex of scutellum and petiole an inconspicuous, almost linear transverse strip (Figs 14, 15: ptl); flagellum with 8 funicular segments........................................ <b>5</b> 5(4) Acropleuron separated from metapleuron by convex, deeply divided upper and lower mesepimeron (Fig. 20: uep, lep); scutellum with carina extending along side from apex of axilla (Figs 2, 14: scc); metanotum with dorsellum V- like protuberant under scutellar apex (Figs 13: dor, 14)........... <b> <i>Metapelma</i> Westwood</b> − Acropleuron extending completely to metapleuron (Figs 21, 41); scutellum without carina along side (Figs 3, 15, 39); metanotum with dorsellum transverse under apex of scutellum (Figs 15, 16, 40)........................................... <b>6</b> 6(5) Mesoscutum with longitudinal parapsidal ridges differentiating elongate-rectangular median mesoscutal region from lateral regions (Fig. 39: psr); mesosternum without transepisternal sulcus (Fig. 41); hypopygium of female extending about half length of gaster (Fig. 35: hyp) [extinct]............ <b> <i>Brevivulva</i> gen. n.</b> − Mesoscutum not differentiated by ridged parapsidal lines (Figs 3, 21); mesosternum with transepisternal sulcus (cf. Figs 24, 26: tss); hypopygium of female extending almost to apex of gaster [extant].............. <b> <i>Lambdobregma</i> Gibson</b>
