Further notes on Philippine odonate karyotypes

Our 1980 stopover in the Philippines coincideo with the occurrence of the typhoon "Osang" (July 25), hence the collecting results were this time again far from spectacular (cf. B. KIAUTA & M.A.J.E. KIAUTA, 1980, Odonatologica 9: 237-245; 1981. he. cil. 10: 151-154). Due to the weather conditions we remained grounded in Manila during July 24-26 (Ri/al Park collection), and left subsequently for Baguio, Benguct Province, in the northern Luzon. Hindered hy frequent showers, we were able to do some collecting (July 28-29) in the hilly area between the Baguio Airport (all. 4921 ft) and l a Trinidad. In all, the Philippine visit yielded only 11 cytologically examined species, among which there are a few taxa that arc cither new to cytology (Ceriagrion lieftincki). or whose karyotypic morphology is of some interest for other reasons (Crcothemis servilia, Orthetrum sabina. Trithemis pallidinervis). Agrioenemis f. femina (Brauer) I f. Manila, 26-VI1. — n=!4. At Im, X the smallest of the set, the smallest autosome bivalent clearly recognizable.
