Luridiblatta undefined-B

description: 12. Luridiblatta sp. B
Fig. 35I
Material studied. LIBYA. 1♀, Mimuna bei Gharian, 20.IX.1906, leg. B.Klaptocz (completely two slides: Bo 1302). (M. Wien).
Description. Size. Female. Length of pronotum: 2.05 mm (tegmina and metanotum not saved).
Colouration. Pronotum and mesonotum not deviating from the generalised pattern; abdominal tergites with three small dark patches (apart from the indistinct lateral ones), median patch of T1 T-shaped: narrowly triangular, laterally along the transversal ridge produced in a narrow stripe (Fig. 35I).
Relationship. The small size of the patches on the abdominal tergites and the shape of the median patch on T1 would allow the alignment to the beybienko- group; the absence of the submesal pair of patches on T2-6 is not contradictory, since these patches may also be weakly developed in other species of the group. But as long as the male sex is not known an exact positioing is not possible.
Determination key mainly for the males of the genus Luridiblatta
1 Transversal ridge of T6 complete, mesally with a short excurvation towards anteriorly (Fig. 1A); tegmina by far not reaching up to the abdominal end, apex fairly transversely cut (Fig. 7H) (longitubulata -group)............................... 3
- Transversal ridge of T6 either incomplete, with a large mesal gap (Fig. 1B), or completely missing (Fig. 1C,D); tegmina at least almost reaching the abdominal end, apex variously shaped.................................................... 2
2 T6 strongly sclerotized, with strongly produced mesal part, transversal ridge with a wide mesal gap or missing at all (Fig. 1B,C); apex of tegmina obliquely rounded (Figs. 19H, 34N) or distinctly obliquely cut (Fig. 22G); genital hook with a quite normally broad shaft, diameter at middle length equals about a fifth of the total length (Fig. 19A–N) (trivittata -group)..... 6
- T6 weakly sclerotized, without produced mesal part, but tergite as a whole curved or angularly bent towards anteriorly, transversal ridge completely missing (Fig. 1D); apex of tegmina symmetrically rounded (Figs. 23F, 34L); genital hook with an unusually broad shaft, diameter at middle length equals about a half of the total length (Fig. 23J,K (beybienkoi- group).... 7
3 Glandular pouches very short, scarcely surpassing T7 (Figs. 14B,C, 17A,B)...................................... 4
- Glandular pouches longer, usually considerably surpassing T7................................................. 5
4 Pit containing pairy vesiclelike structures (Fig. 17B), anterior pit wall without transversal crest, transparent window very small, usually hidden behind the vesicular structures, stabilising bracelet throughout rather slender (Fig. 18A–H)......................................................................................... Luridiblatta vesiculosa sp. nov.
- Pit without vesiclelike structures, anterior pit wall with a ridgelike transversal crest laterally narrowing the well developed transparent windows, stabilising bracelet rather broad and often further broadening in its lower half (Figs. 13F, 14A,B)................................................................................ Luridiblatta fenestrata sp. nov.
5 Glandular pouches usually much longer than length of T7 at its lateral border (Fig. 10A–F); anterior pit wall near the opening usually without hump (Fig. 8A, but see 9G)..................................... Luridiblatta longitubulata sp. nov.
- Glandular pouches usually shorter than length of T7 at its lateral border (Fig. 12A–F); anterior pit wall usually with a pair of bulges protruding into the pit hole (“hump”, Fig. 11C)............................... Luridiblatta gibberosa sp. nov.
6 Transversal ridge of T6 only laterally present, large clavate bristles distributed only in the posterior half of the tergite (Fig. 1B); apex of tegmina obliquely rounded (Fig. 19H)................................ Luridiblatta trivittata (Serville, 1839)
- Transversal ridge of T6 completely missing, area covered with large clavate bristles laterally extended till near to the anterior border of the tergite (Fig. 1C); apex of tegmina obliquely cut (Fig. 22G)................. Luridiblatta habbachii sp. nov.
7 Genital hook: crest of claw short, triangular, without antlerlike processes (Figs. 23K, 24D,E)........................................................................................... Luridiblatta quadrivittata (Chopard, 1963)
- Genital hook: crest of claw large, with two rather broad antlerlike processes (Fig. 25K,L)............................ 8
8 Mesal dark stripe of pronotum in both sexes rather broad and twice intermittent still further broadened, at the anterior end suddenly strongly narrowed (Fig. 34G–K); female tegmina apically weakly convex.......... Luridiblatta cyprica sp. nov.
- Mesal dark stripe of pronotum in both sexes rather narrow, towards anterior gradually further narrowing; female tegmina apically shallowly concave............................................................................. 9
9 T7: Anterior border of the pit opening wall towards laterally continuing into a narrow edge converging with the transversely running gutter, both ending at close distance near the lateral border of the tergite (Fig. 33H–J); glandular tubules rather massive, usually very well visible, towards apically broadening.................................. Luridiblatta graeca sp. nov.
- T7 without such an edge (Fig. 33B–D); tubules not massive, often hardly visible, towards apically not broadening.............................................................................. Luridiblatta beybienkoi (Mařan, 1957)
