Diagnosis. Together with H. adelungi the only members of the bolivari -group having the spine pattern [8.7.4] on the hindtibia, distinguished from the latter species by the smaller size, the colouration of the pronotum, and shape and colouration of tegmina.

Material studied. Syntypes, 2♂, Mogador, Mz. Escalera (prep.: Bo 1356, Bo 1359). (M. Madrid) .

Description of male. Size. Length of pronotum: 4.7 mm; length of tegmina 15 mm.

Colouration. Head. Vertex dark brown, face lightly coloured, whitish to ochreous. Pronotum along the anterior margin with lightly coloured, towards the middle strongly broadening band, median third transparent, but narrowed by a brownish triangle arising from the darker posterior surface, lateral parts of the band whitish yellow; posterior surface in the center light brown, towards posteriorly and laterally darker brown. Tegmina with anal field medium brown, remaining surface much lighter coloured, costal field whitish transparent, anal furrow and a broad stripe accompanying the subcosta posteriorly along its basal part transparent ( Fig. 20C ). Remaining body ochreous.

Head. Distance between eyes greater than between ocelli, the latter as great as or slightly smaller than diameter of ocelli; interocellar depression without distinct foveolae, interantennal area with a pair of elevations fairly reaching the height of the clypeus.

Pronotum. Anterior border mesally with a weak sinusoidal projection, lateral borders subtruncate.

Wings. Relatively short. Tegmina more elongate than in the preceding species, anterior border at a third of the length with a posterior deflection followed by a shallow concavity, apex fairly mesally ( Fig. 20C ).

Other characters. Tibia armament: [1.8.0][6.8.1][8.7.4], dorsal spines of the hindtibia in two groups à 5 and 3, ventral spines in two groups à 2.—Cercal tricholiths: Fig. 19B .—Subgenital plate: Fig. 4G .—Right phallomere: Fig. 4H .

Female: Chopard 1929, 342.

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.

FIGURE 20. Left tegmen of male.—Species: A: Heterogamisca adelungi, Holotype; B: H. jeffreyana, Holotype; C: H. bolivari, Syntype (same specimen as used for prep. Bo1359); D: H. bifoveolata, Lectotype; E: H. longipilosa, Holotype; F: H. brevipennis, Holotype; G: H. cerverae (same specimen as used for prep. Bo 1365). The tegmina are photographed from microscopical preparations with transmitted light; the black netlike markings in the costal field are in reallity intransparent whitish deposits.—Enlargements: Scale 3 mm, same for all figures.
