Figs. 15J , 19A

Male characters. Wings: fully developed, tegmina with subcosta lobe.—Femur armament: femora of all legs with an apical spine.—Tibia armament: number of apical spines on the fronttibia either seven [2.7.0] or eight [1.8.0][n.7.n][n.7.n] (see discussion under II.5.B.). Chopard (1929) states for the fronttibia of all species of Polyphaga [1.7.0], an armament which I have only found in the genus Eremoblatta ; Bey-Bienko (1950) gives numbers only for P. sinensis : [1.8.0] (but see next paragraph). — Subgenital plate: bristles distributed only along the posterior margin, with styli.—Right phallomere: Type 7, Fig. 15J .—Supraanal plate: very short, posterior border convex.—Cercal tricholiths:>5 per anulus, Fig. 19A .

Remarks. An exact determination of the specimens available for study was not possible; E. spec. 1 and 2 are certainly different species, both were determined by Bey-Bienko as E. sinensis . The right phallomere could only be studied in E. s pec. 2 and 3, since E. s pec. 1 is without abdomen. Both show agreement in the structure of the right phallomere, which is very different from that of Polyphaga .

A revision of the genus was published by Qui et al. (2018) containing the descriptions of numerous new species. Unfortunately, the armament of the legs is not treated in the paper.

A: Male subgenital plate in ventral view, arrow points to fine long bristles inserting on the dorsal surface of the plate; B–F: Male supraanal plate with paraprocts, in dorsal view; G–J: Posterior part of the right phallomere, in standard view.—Species: A,B,G: Anisogamia tamerlana, Bo 1401; C: Heterogamodes ursina, Bo 1357; D: Mononychoblatta semenovi, Bo 1391; E: Heterogamisca cerverae, Bo 1365; F: Mollidentoblatta marmorata, Bo 1382; H: Polyphaga obscura, Bo 1396; I: Polyphagina algerica, Bo 1376; J: Eupolyphaga, spec. 2, Bo 1367.—Phallomere types: G,H: Type 4; I:Type 8; J: Type 7.—Explanations: R1M (in I almost membraneous), R2, R3 sclerites of the right phallomere, MD main dent of R2, not stepped, in (H) with a concavity at the backsite (arrow), in (I) very flat, in (J) with a gutter on the upper surface (arrow); c cercus, p paraproct, s stylus.—Enlargements: Scale 0.25 mm.

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.
