We report here the results from field trips to collect Odonata in the northeastern parts of Kelantan state and the north of Terengganu state, Peninsular Malaysia. Eighty four species were collected, and four of these are new records for the state Kelantan and 10 are new records for the state of Terengganu. Notable records obtained from the field trips were Euphaea masoni, Coeliccia sameerae, Pseudagrion ?lalakense, Leptogomphus tioman and Macromia cupricincta. Checklists for Kelantan (140 species) and Terengganu (132 species) are given in an appendix.
Previously unpublished records of Odonata from the states of Negeri Sembilan and Selangor in Peninsular Malaysia are presented. One hundred and eight species are listed, of which 77 were collected in Negeri Sembilan and 87 in Selangor. Fifteen of the species recorded from Negeri Sembilan and seven of those recorded from Selangor appear to be first records for the respective state. Notable records include Drepanosticta sp. cf hamadryas Laidlaw, 1931, Rhinocypha pelops Laidlaw, 1936, Acrogomphus ?malayanus Laidlaw, 1925, Heliogomphus kelantanensis (Laidlaw, 1902); Onychogomphus duaricus Fraser, 1924, Macromia cupricincta Fraser, 1924, Idionyx montana Karsch, 1891, Chalybeothemis chini Dow, Choong & Orr, 2007 and Hylaeothemis clementia
Ris, 1909 Ris, 1909. Provisional checklists of the Odonata known from Selangor plus the
Federal Territory of Kuala Lumpur (171 species) and for Negeri Sembilan (116 species)
are given in appendices.
The birdwing butterfly Trogonoptera brookiana (Wallace, 1855) is a well-known conservation icon, yet questions remain about the infraspecific status of regional populations. The eastern Peninsular Malaysian population has been described as the subspecies mollumar d’Abrera, Doggett & Parker, 1976, but its status as a subspecies distinguishable from the taxon trogon (Vollenhoven, 1860) in Sumatra has been disputed. Wing characters and measurements of specimens from the two regions were therefore examined quantitatively using discriminant function and correspondence analyses. Eastern Peninsular specimens differ on average from Sumatran specimens in having more extensive green, especially in the female. This is reflected in many of the measurements and characters analysed. Females from the Peninsula also have a characteristically blacker upperside ground colour in which the outer areas of both wings barely contrast with the black veins and forewing cell. The extent of these differences enables a reliable differentiation of the females of both regions. The magnitude and consistency of differences are comparable to that between other subspecies of undisputed status. Behavioural differences also exist. The name mollumar therefore merits subspecific status. In addition, we consider the male forms walshi Haugum & Low, 1982 and walshoides Haugum & Low, 1982 to be chemically discoloured specimens of trogon rather than biological forms.
Records of Odonata from Kuching and Samarahan, the western administrative divisions of Sarawak in Malaysian Borneo, are presented. Forty-two species are listed from Bako National Park, and eighty-nine species are listed from various other locations. Notable records, not yet publishedin detail elsewhere, include Aciagrion ?fasiculare, Bornargiolestes species, Pericnemis species cf triangularis, Coeliccia new species and Tetrathemis flavescens.
Odonata records from Ayer Hitam Forest Reserve and the surrounding area in Johor, Peninsular Malaysia are presented. A total of 44 Odonata species from eight families were collected in the area in October 2012. All of these records are new to Ayer Hitam Forest Reserve. Indothemis carnitica is a new record for Malaysia.
