Cassola, F., 2005. Studies of tiger beetles. CLXII. A new Cylindera (subgenus Leptinomera) from Sabah, Malaysia, with records of other species (Coleoptera: Cicindelidae). – Tijdschrift voor Entomologie 149: 203-207, figs. 1-2. [issn 0040-7496]. Published 1 December 2006. A new species, Cylindera (Leptinomera) duffelsiana sp. n., is described from the Tawau river in southeastern Sabah, Malaysia, and some new distributional records of other species from Sabah are given. The subgenus Leptinomera now includes 20 species, of which 13 occur in northern Borneo. A checklist is provided. Dr. Fabio Cassola, Via F. Tomassucci 12/20, I-00144 Roma, Italy.

Note. – This is probably the most common species of the genus, known from Sumatra (where it was first described) and Malacca. Records from Bor- neo (Horn 1931; Cassola 1983) need confirmation, as misidentification of specimens is a possibility. C. (L.) catoptroides is bronze greenish in colour, with four evenly-sized elytral dots, metallic legs, and a

1 mm short half-testaceous labrum.

Note. – This species, apparently endemic in Sabah, was for a long time only known from two female specimens from the Mt. Kinabalu area (Cassola 1983). Wiesner (1989) recorded some additional specimens and described the male. Like C. (L.) catoptroides, it is dark bronze in colour, with four similarly-sized elytral dots (rarely just two), metallic legs, and a short half-testaceous labrum, but the females have smooth and shiny shoulders and a large round elytral mirror (males, in contrast, have matt shoulders). Moreover, b the sides of pronotum are slightly pubescent.
