Figs. 2A,E , 3D , 5A,B , 20E , 21A

Etymology. The species name refers to the long hairs (Latin pili) on various parts of the body.

Diagnosis. Tegmina as in the following species slightly marbled, distinguished by differences in shape and colouration of the tegmina and differences in leg structures.

Material studied. Holotype, 1♂, Moroc, Agadir-Ademine , 2.–21.XI.1974, G. Friedel leg. (prep.: Bo 1329). — Paratype, 1♂, same data as holotype (prep.: Bo 1358). ( ZSM) .

Description of male. Size. Length of pronotum: 4.5 mm; length of tegmina 15.0– 15.5 mm.

Colouration. Head with vertex and frons dark brown, almost black, postclypeus reddish, anteclypeus and labrum straw-coloured. Pronotum along the anterior margin with lightly coloured, towards the middle strongly broadening band, median third transparent, lateral parts orange; posterior surface brown, in the center lighter brown with darker marbling, towards posteriorly and laterally darker brown ( Fig. 21A ). Tegmina pale brownish, almost transparent, faintly darker marbled, anal field slightly darker brown, dark brown stripe along the basal part of the subcosta, anal furrow transparent, costal field whitish transparent ( Fig. 20E ). Remaining body ochreous.

Head. Eyes and ocelli equidistant, distance equals diameter of ocelli. Interocellar depression without distinct foveolae.

Pronotum. Anterior border mesally with a weak sinusoidal projection, lateral borders subtruncate ( Fig. 21A ).

Wings. Relatively short. Tegmina rather broad, in the last third of the length narrowing to the almost angularly rounded apex situated far anteriorly, anterior and posterior border quite regularly rounded, weakly in the first, more strongly in the latter; with about 16 veinal branches in the discoidal field ( Fig. 20E ).

Other characters. Hindfemora: along the ventral edges—in contrast to H. jeffreyana — without tiny spinules ( Fig. 2E ).—Tibia armament: [1.8.0][6.8.1][(9)10·7·4], dorsal spines of the hindtibia in two groups à (6)7 and 3, ventral spines in two groups à 2, spines of the proximal pair at some distance; hindtibia especially proximally with very long bristles reaching the length of the spines ( Fig. 2A ).—Subgenital plate: Fig. 5A .—Right phallomere: Fig. 5B .

Female: unknown.

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 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.

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.

FIGURE 21. Pronota of some species of the genus Heterogamodes. Species: A: Heterogamisca longipilosa, Paratype; B: H. sulcata, Holotype (Bo 1417); C: H. cerverae (Bo 1360); D: H. pallens, Holotype; E: H. senegalensis (Bo 1419); F: H. zolotarevskyi (Bo 1418). Transparent parts of the pronotum appear dark due to the dark background; it mainly concerns a relatively large area mesally at the anterior margin, in (B) additionally an apparently dark band at the lateral margins. Preparation numbers between parentheses indicate that the same specimen was also used for the production of microscopical preparations.— Enlargements: Scale 2 mm.
