C. Subgenus Leiopteroblatta Chopard, 1969 , stat. nov.

Type species. Leiopteroblatta monodi Chopard, 1969

Diagnosis. Distinguished from the other subgenera by the shortened wings and the spineless midtibia.

Male characters. Wings: strongly shortened and veinless, scarcely supassing the abdominal end.—Tibia armament: armament of fronttibia [1.5.0]; midtibia slightly flattened, without any spine [0.0.0]; hindtibia distinctly broadened and flattened, ventrally with a row of 4 long spines including one apical spine, dorsally at the end of the tibia with a second apical spine [0.2.3], but no proper dorsal spines.—Subgenital plate: presumably without stronger bristles (specimen not available for making microscopical preparations).—Right phallomere: Type 5b, Fig. 13B .

Female: unknown.

Number of species: 1 (No. 38).

Figures

FIGURE 2. Leg structures. A–E: Distinguishing features between the species Heterogamisca longipilosa, Holotype: A, proximal part of left hindtibia, E left hindfemur, both mirror images,—and H. jeffreyana, Holotype: B, proximal part of right hindtibia, C right hindfemur, arrows delimit the area shown in higher enlargement in D. Notice the longer bristles on the tibia of H. longipilosa, and the tiny spinules along the anterio-ventral edge of the hindfemur in H. jeffreyana, which are missing in the other species. F: Right hindtibia of the female of Nymphrytria mirabilis (specimen from Erg er Raoui, view on the anterior surface), showing the row of five large spines along the ventral edge of the broadened tibia, row formed by four ventral (ve) and one apical spine (a). At the bottom parts of the leg from the other side are visible. G: Left midtibia of the same specimen (view on anterio-dorsal surface), the seven dorsal spines (do) arranged in two longitudinal rows, the row at the right is completed by one apical spine.—Further abbreviations: Fe femur, Ti tibia, Ta tarsus.—Enlargements: Scale in D 0.2 mm, in all others 0.5 mm.

FIGURE 12. Subgenital plate (at the left, ventral view) and posterior part of the right phallomere (at the right, standard view) of male.—Species: A,B: Mollidentoblatta simillima. (A) Holotype, Bo 1384; (B) Bo 1363; C,D: Hemelytroblatta cypria, Bo 1281, right stylus lost; E,F,I: Mononychoblatta semenovi, Bo 1391; (F) in standard view, (I) main dent in ventral view, showing its backside; G,H: Nymphrytria mirabilis, from Erg er Raoui; (H) in fairly ventral view.—Phallomere type: B,D,F,I: Type 2; H: Type 5a.—Explanations: R1M, R2, R3 sclerites of the right phallomere; MD main dent of R2, stepped, ue its upper etage (B, D, F), or not stepped (H); r ridge with unregularly sculptured surface; s stylus.—Enlargements: Scale in H and I 0.1 mm, in all others 0.25 mm.

FIGURE 13. Subgenital plate (at the left, ventral view) and posterior part of the right phallomere (at the right, standard view) of male.—Species: A: Nymphrytria mirabilis, detail from Fig. 12G; B: Leiopteroblatta monodi, Holotype, in fairly ventral view; C,D: Psammoblatta livida. (C) Bo 1334; (D) Bo 1395; E,F: P. longipes, Holotype, Bo 1422; G,H: P. minuta, Type, Bo 1400.— Phallomere types: B: Type 5b; D,F,H: Type 6.—Explanations: R1M, R2, R3 sclerites of the right phallomere, MD main dent of R2, not stepped, in D, F appearing divided by a short incision between its horizontal (ha) and vertical arm (va).—Enlargements: Scale in B 0.1 mm, in all others 0.25 mm.
