Figures

FIGURE 3. The right phallomere and its parts. A: Complete right phallomere of Type 1 in standard view, seen from the left (inner face) towards the right (outer face); the position of the other two axes of the body are indicated by the labels ant(erior)— post(erior) and dors(al)—ventr(al). The three sclerites of the phallomere are R1M, R2, and R3. The largest dent of R2 is called main dent (MD), in this case stepped in two etages, upper etage (ue). R1M with a tubercular ridge (tr), the two arrows point to an edge where R1M and R2 articulate. B: Most posterior part of Type 6 phallomere in ventral view, showing the frontside of R1M and the backside of the main dent, with its vertical arm (va) in focus, the horizontal arm (ha) out of focus. C,D: Isolated R1M sclerite, with the sclerotised part (sc) at the left, in D (Type 1) with a tubercular ridge (tr), the membraneous part at the right, in C (Type 2) with a gutterlike deepening (g), arrows indicate where R1M articulates with R2. E–G. Phallomeres in ventral view showing the backside of the main dent, R1M with a ridge (r). E: Phallomere Type 1/2, r of R1M as in Type 2 without tubercular elevations, ue in outline rounded as in Type 1, but with a small lobelike projection (l) recalling the pointed tip of Type 2. F,G: Type 3 phallomeres, main dent with a deep incision (arrow).—Species: A: Heterogamisca arenarum, Type; B: Psammoblatta minuta, Type; C: Mollidentoblatta persica, Holotype; D: Heterogamisca longipilosa, Holotype; E: Atuberculoblatta intermedia, B 1416; F: Fissidentoblatta afghana, Paratype; G: F. polyphagella, Holotype.—Enlargements: Scale in B 0.1 mm, in all others 0.25 mm.

FIGURE 5. Subgenital plate (at the left, ventral view) and posterior part of the right phallomere (at the right, standard view) of male.—Species: A,B: Heterogamisca longipilosa. (A) Holotype, Bo 1329; (B) Paratype, Bo 1358, dents of R2 sclerite isolated; C,D: H. jeffreyana, Holotype, Bo 1328; E,F: H. sulcata, Holotype, Bo 1417; G,H: Heterogamisca arenarum, Type, Bo 1430.— Phallomere type: Type 1 in all corresponding figures.—Explanations: R1M, R2, R3 sclerites of the right phallomere, MD main dent of R2, ue its upper etage; tr tubercular ridge.—Enlargements: Scale 0.25 mm.
