Table 2. Explanation of the synapomorphies in Fig. 4 1.C-sclerites located at the apex of the epiphallic arm(B-sclerite without any particular development),from which they are distinctly separate.2.Endophallic apodeme without mediodorsal crestbetween endophallic sclerite and apex of ectophallicfold.3.Ectophallic arc extended above ectophallic fold, andprotruding beyond it.4.Male metanotal gland globose.5.Epiphallic sclerite with visor-like median projection.6.Epiphallic parameres 1 and 2, large, spine-like.7.Mesotibia with two apical spurs.8.Median inner apical spur of metatibia longer thandorsal apical spur.9.C-sclerite reduced, forming a soft, quadrangularlobe.10.Ectophallic apodemes large and robust, with anabutment that supports the epiphallic sclerite.11.Lateral lamina of endophallic apodeme markedlyelongate.12.Epiphallic–ectophallic membrane with pair ofnon-glandular invaginations.13.Epiphallic paramere 2 elongate, bordering the entiredorsal surface of the epiphallic arm.14.Membrane separating the A-sclerite from theepiphallic parameres inflated, displacing theA-sclerite posteriad of the basal plate of theC-sclerite.15.Metafemora very thin, even basally.16.C-sclerite differentiated and complex, comprising along, thin plate, a lateral spine or notch, and amore or less developed ventral pouch.17.C-sclerite vertically articulated with epiphallic arm.18.Invaginations of epiphallic–ectophallic membranedeveloped into two large glands.19.Membrane between A-sclerite and epiphallicparameres greatly developed, altering the entireshape of the epiphallic arm.20.C-sclerite with a large glandular system formed bythe ventral pouch and the lateral spine, located onthe outer face of the epiphallic arm.
