Dziriblatta (Dziriblatta) pilleata , spec. nov. Figs. 2J , 3I , 7A–I , 27 , 28 , 29 Etymology. The species name refers to the caplike ( pilleus in Latin) shape of the pouch lobes. Diagnosis. Distinguished from the preceding three species by the differently shaped tergites T6,7 and extremely short and apically more or less transversely cut pouch lobes. Material studied. Type material. SPAIN . Holotype , 1♂ , ex L, Prov. Cádiz , Nuevo Castellar (ca. 20 km N Algeciras), ca. 100 m , leg. B. & H.Bohn , 27./ 28.III.1988 (completely on two slides: Sp 187/13). ( MNMS ). Additional material. SPAIN . Same data as holotype: 1♀ ; same locality as holotype : 5♀ , 1. V .1997 ( Sp 187a). ( Coll. Bohn , ZSM ) . Description. Size. Length of pronotum in the male 2.18 mm, relative length of pouch lobes 37% ( Table 2 ). Male structures. ( Figs. 7A–I ). Posterior borders of T4,5 slightly concave, T6 with a very deep sinusoidal excavation, posterior border of T7 also deeply concave, latero-posterior corners narrowly triangular, latero-anterior shoulders not developed, broadly rounded ( arrow in Fig. 7D ); bottom of trail sievelike due to numerous glandular pores ( Fig. 7H ); lateral gutters and holes distinctly curved posteriad; pouch lobes very short, caplike, with almost transversely cut tip ( Fig. 7D, E ); bristles similarly as in the preceding species with long bristles loosely distributed over the full width of the pit opening, but all strongly and unregularly curled ( Fig. 7F, G ). Glandular pores laterally on T2: present, but in low numbers along the anterior border of the tergite ( Fig. 2J ). Distribution. Spain , Andalusia : One locality near Algeciras at an elevation of 100 m ( Figs. 27 , 28 ). Remarks. The singular male specimen available shows strong differences to all other species of the subgroup in the shapes of T6 and T7 and in the shape and length of the pouch lobes. The differences are strong enough to consider it as a different species. However, the specimen was grown from a juvenile; it cannot be excluded that the development of the structures is modified by the unnatural conditions of the life in captivity. The reason for the doubt is, that the margins and surfaces of T6 and T7 show slight but unusual undulations, which could be interpreted as signs for an incomplete stretching of the cuticle after moulting. However, numerous specimens of the two preceding species had also been reared from larvae (as the specimens from Fig. 5D, E ) but did not show any abnormalities apart from a possibly lighter colouration. Since in the decisive structures of pouch and pits no signs of an abnormal development can be seen it appears justified to consider the specimens from locality Ma 186 as representatives of a new species.
