Description of a new Cylindera WESTWOOD, 1831, species |
Abstract. Cylindera (Cylindera) oester- lei sp. nov. from Sichuan province of China is described. It can be distinguish from the most similar Cylindera (Cy- lindera) lautissima (DOKHTOUROFF, 1888) by its elytral coloration, shape of pronotum, and morphology of inner sac of aedeagus. |
Zusammenfassung. Cylindera (Cylin- dera) oesterlei sp. nov. wird aus China beschrieben. Sie ist anhand der Flügel- deckenfarbung, durch die Form des Pro- notums und Details des Aedeagus von der ahnlichen Cylindera (Cylindera) lau- tissima (DOKHTOUROFF, 1888) zuunter- scheiden. |

Introduction In recent years, numerous Cylindera (Cy- lindera) lautissima (DOKHTOUROFF, 1888) or at least lautissima-like tiger beetle specimens have been received by tiger beetle researchers in many parts of the world. In 1996, ANDREAS OESTERLE (Leutenbach), at the Prague Bourse, firstly recognized one of these taxa as new species but rele- gated the writing of descriptions to other authors. In the meantime SAWADA & WIESNER (2002: 145) reported two populations of C. lautissima from the Chinese province of Gansu with different-shaped body proportions, and CASSOLA (2002: 88, 89, and Fig. 1), who moved lautissima from Pro- thyma HOPE, 1838, to Cylindera WESTWOOD, 1831, also mentioned two different- shaped specimens (from the provinces of Gansu and Sichuan). Subsequently we re- ceived additional specimens of lautissima- like beetles, collected by ANDRE GORODINSKI (Moscow) in Sichuan and take the opportunity to describe the new species in the following, accompanied by a redescripti- on of C. (C.) lautissima. |

Ecology. On a steep slope in scrub-bush area (juniper forest) running and flying on open ground, some specimens in pitfall traps (BENES in litteris).
Differential diagnosis. Differs from C. (C.) lautissima by absence of white spots on elytra, shorter pronotum (Fig. 13) and short flagellum of aedeagus.
