LADERRICA WAHL & SIME , GEN. N.

Type-species. Laderrica feenyi Wahl & Sime , sp. n. Description. Flagellum of female lanceolate, with flagellomere 3 2.9¥ as long as wide; flagellum of male unknown. Clypeus flat and wide, apicolateral margin forming an angle of approximately 40°, punctures evenly distributed, apical 0.3 not thinned, apical margin straight and without median projection. Mandible long and evenly tapered to apex, ventral tooth in same plane as dorsal tooth. Supra-antennal area without median paired ridges or denticles. Vertex with posterior section about as long as ocellar triangle, gently sloping to occipital carina. Gena convex in dorsal view. Juncture of hypostomal and occipital carinae separated from mandible by about 0.5¥ basal mandibular width. Occipital carina with ventral region above mandible not produced as a low flange.

Pronotal flange low and with posterior face concave. Epicnemial carina dorsally complete. Scutellum conical; lateral carinae absent. Central convexity of metanotum not widened and lateral depressions not reduced. Base of propodeum rising steeply and abruptly. Areola reduced, completely filled-in and appearing as polished boss. Anterior transverse carina absent; posterior transverse carina complete; lateral longitudinal carinae present; median longitudinal carinae absent. First lateral area with regularly distributed punctures; second lateral area rugosopunctate. Metapleuron rugosopunctate. Juxtacoxal carina absent. Propodeal lateral profile steeply sloping. Scopa absent. Cell 1 + 2Rs of fore wing petiolate, vein 2/Rs <3r-m, vein 2m-cu interception apicad midpoint of posterior margin (vein 2/M 2.5¥ as long as vein 3/M).

MS 1 in lateral view evenly curved with highest point at middle, petiole laterally compressed (similar to Fig. 24); sclerotized anterior portion of S1 about 0.9¥ as long as distance from posterior margin of anterior portion to apex of T1; petiole basally without dorsal or lateral bulges; median longitudinal carinae absent, median field present, punctures fine and dense and without rugae. Ventral margin of T2 simple. T2-4 with longitudinal rugae restricted to median basal 0.2 of T2, absent on other tergites. T2-4 evenly convex, with normal punctures separated by about 0.5¥ their diameter. T2-5 not basally constricted and without dorsolateral ridges. S2 divided, S3-5 entire. Apex of female metasoma with T7-8 projecting well beyond apex of T6; amblypygous.

Autapomorphies. Scutellum conical (#20–2); median longitudinal carinae of propodeum absent (#33–1); MS 1 in profile evenly curved with highest point at middle, petiole laterally compressed (#42–1).
