Eucorydia dasytoides (Walker, 1868)

Figs. 16G,H , 19E

Male characters. Wings: fully developed, tegmina with subcosta lobe; right tegmen specialised, with a sharp edge at the borderline between the two differently structured areas, Fig. 19E .—Femur armament: femora of all legs with an apical spine.—Tibia armament ( E. purpuralis ): [3.6.1][7.6.3][11.6.4].—Subgenital plate: anterior apodemes inconspicuous, bristles on posterior third of the plate, with rather long styli, Fig. 16H .—Supraanal plate: short, latero-posterior corners rounded, posterior border shallowly concave (more rounded than to be seen on the figure), Fig. 16G .—Cercal tricholiths: absent.

Female: Wings as in the male fully developed and similarly specialised.

FIGURE 16. Supraanal plate with praprocts (at the left, dorsal view) and subgenital plate (at the right, ventral view) of male.— Species: A,B: Homoeogamia mexicana, Bo 1181; C,D: Ergaula cf. capensis, Bo 1185; E,F: Therea cf. petiveriana, Bo 1377; G,H: Eucorydia dasytoides, Bo 1390.—Abbreviations: c cercus, p paraproct, s stylus.—Enlargements: Scale 1mm.

FIGURE 19. A–C. Cerci of male with tricholiths, ventral view, all species with more than five sensilla per anulus.—Species: A: Eupolyphaga spec. 2, Bo 1367; B: Heterogamisca bolivari, Syntype, Bo 1356; C: Mononychoblatta semenovi, Bo 1391; D: Heterogamisca cerverae, Bo 1404.—E–H. Right tegmen with specialisation for the fixation of the left tegmen at rest.— Species: E: Eucorydia dasytoides, from Formosa, Kosempo; F: Therea cf. petiveriana, from S-India, Shevaroy Hills; G: Ergaula cf. capenesis; H: Homoeogamia mexicana. The arrows pointto the positions where the borderline between the two different areas crosses the anal furrow; the whitish patches along the borderline in E are especially shiny parts of the specialised surface;af anal furrow; sa specialised area; us unspecialised area.—Enlargements: Scale 2.5 mm.
