FIGURE 2. a–c in Generic classification for the Gasteruptiinae (Hymenoptera: Gasteruptiidae) based on a cladistic analysis, with the description of two new Neotropical genera and the revalidation of Plutofoenus Kieffer

FIGURE 2. a–c: Gasteruption bispinosum, delimitation of the measurements and some characters of cladistic analysis. a: lateral view; b: head in dorsal view; c: propleuron in ventral view; d: Gasteruption nasutum, left hind tarsus. Measurements: Head: i: head length; ii: eye length; iii: malar space height; iv: distance between posterior ocellus and occipital margin (dorsal view); v: distance between posterior ocelli (dorsal view); vi: scape length; vii: pedicel length; viii: first flagellomere length; ix: second flagellomere length; Mesosoma: x: propleuron length; xi: propleuron width (ventral view); xii: mesosoma length (excluding propleuron); xiii: mesosoma height (distance between metasoma insertion and base of middle coxa); xiv: pronotum length (distance between anterior margin of pronotum and tegula); xv: distance between anterior margin of pronotum and metasoma insertion; xvi: hind coxa length; xvii: hind coxa width; xviii: hind femur length; xix: hind tibia length; xx: hind tibia width; xxi: hind first tarsomere length; Metasoma: xxii: metasoma length; xxiii: ovipositor sheath length; xxiv: body length (measurements i+x+xv+xxii). The following ratios were used in the species descriptions: xxiv/xxiii, i/ii, ii/iii, iv/v, viii/vi, viii/vii, viii/ix, xii/xiii, x/xi, x/xiv; xvi/xvii, xix/xx, xix/xviii, xix/xxi, xxii/xii, and xxiii/xxii. Arabic numbers indicate characters and respective synapomorphic states (within brackets).
