Steinmann, H.: Brindleiana atlas gen. et sp. n. from SE Asia and taxonomical notes on Allodahliinae (Dermaptera, Forficulidae)

3 (2) Scapus long, almost as long as frontal section between scapi; bending onto eyes reaching nearly their posterior margins. Basal section on inner margin of male cercus without a pair of teeth, subsequent margin with 2 pairs of teeth, characteristic of Allodahlia species. Pygidium wide, its lateral angle without peg, plate triangular. Oriental Brindleiana gen. n. 4 (.1) Elytra not shortened, considerably longer than pronotum, lateral margins with an expressed ridge-like rim, more or less lamelliform. Winged species Allodahlia VERHOEFF, 1902 Eulithinus HINCKS, 1935 Head wide, smooth, eyes small, situated near scapi. Seapi small, only slightly longer than wide. Pronotum wide, flat; lateral margins slightly elevated like a ledge. Elytra short, rudimentary, rather squamiform, their posterior margins meeting in an obtuse angle. W'ingless species. Type-species: Lithinus analis RAMBUR, 1838 Small, length of body without cerci 6—7 mm. Ultimate male tergite wide; posterior margin largely transverse, but margin visibly and convexely crenellate. Basal section of cerci curved, apically straightened, beyond a straight section incurved. Pygidium wide, trapezoid, lateral angles peg-shaped. Male genitalia forficuloid in type; metaparameres long, narrow, more than five times longer than wide. Virga short, basal vesiculum resembling that of Forjicula species, curved in about 200°. — Distribution : Spain analis (RAMBUR, 1838) Allodahlia VERHOEFF, 1902 Robust animals with a wide body. Generally black, blackish brown or brown. Antennae shorter, joint 4 about as long as or shorter than joint 3. Mesosternum wide. Lateral margins of elytra with a ledge-like rim. Eyltra wide, their shoulders rounded, wings whole. Male cerci characteristic, longer or shorter, but horizontally and vertically more or less arcuate ; inner margins with one or two pairs of teeth. Pygidium with specific features well visible in a superior view; useful in identifications of species. Female cerci simpler, elongate. Male genitalia simple; genital lobe unpaired, virga within it long, sclerotized, or only basally so. Type-species: Forjicula scabriuscula SERVII.EE, 1839 Key to species of Allodahlia VERHOEFF (partially after BRINDLE) 1 (2) Elytra tuberculate; almost entirely dull blackish species when fully mature. Pronotum with anterior angles produced. Posterior margin of male pygidium more or less truncate. Cerci comparatively thin, narrow and long; slightly arcuate as compared to those of its congeners, inner margins with a well discernible tooth (Fig. 1). — Distribution: India, Bhutan, Viet-nam, Java, Sumatra, Borneo, Formosa, South China, Philippine Islands scabriuscula (SERVILEE, 1839) 2 (1) Elytra not tuberculate, sometimes strongly rugose. Pronotum not produced at anterior angles. Posterior margin of male mygidium rounded, produced medially, or with spines. 3 (8) Wings entirely yellow, or yellow at base. Elytra darker in colour. 4 (5) Wings entirely yellow. Each branch of male forceps more or less undulate, either strongly (Fig. 2) or weakly curved, and with one or two teeth on the inner margin of each branch. — Distribution : Burma, India orientális, Sikkim ochroptera BRINDLE, 1972
