PSILIDAE – L. PAPP & B. MERZ

In the CDO there is no record of Psilidae from Thailand. There is no comprehensive work on for the Oriental Psilidae after FREY’ s (1955). His specimens were from NE Burma, i.e. any of them may occur also in Thailand. IWASA (1989, 1991, 1992) published good papers on the Japanese species of Chyliza , Psila s.lato and Loxocera , respectively, which are useful aids even when studying Oriental species. In two reviews on the Asian species of Chyliza and Loxocera, SHATALKIN (1998 a , b) described Chyliza kaplanae (p. 104, Doi Suthep ) and L. (Asiopsila) freidbergi (p. 94, Mae Sariang) from Thailand.

The psilid specimens in the MHNG were identified by A. I. SHATALKIN.

Asiopsila kambaitiensis (FREY, 1955) – 1 f: N Thailand, Chiang Mai Province , Doi-Suthep National Park , What Phrathat, 950 m, 17.X.2000, leg. B. Merz & P. Schwendinger ( MHNG); 1 m: N Thailand, Chiang Mai Province , Doi-Suthep National Park , What Phrathat, 1100 m, 17.X.2000, leg. B. Merz & P. Schwendinger ( MHNG). New for Thailand .

Chyliza munda ( WALKER, 1860) – 2 f: N Thailand, Mae Hong Son Province , 22 km N Mae Hong Son, Tong Palace, 930 m, 21.X.2000, leg. B. Merz & P. Schwendinger ( MHNG); 1 f: N Thailand, Chiang Mai Province , Huai Nam Dang National Park , 18 km E Pai, 1720 m, 22.X.2000, leg. B. Merz & P. Schwendinger ( MHNG). New for Thailand .

In 2004 we selected and pinned ten specimens, an eleventh one was captured in 2003 and we also published a psilid fly from Vietnam below (the HNHM specimens were – partly – identified by L. PAPP).

Chyliza? elegans HENDEL, 1913 – 1 m: PF04/25; 1 m: PF04/30; 1 f: PF04/43. As PAPP (2005) suggested recently, a revision of the Oriental species of Chyliza (a species rich genus in this region) is much needed. In the frame of that work, a review of our specimens will also be advisable.

Loxocera? maculipennis HENDEL, 1913 – 1 m: PF04/7; 2 f: PF04/8; 2 f: PF04/1; 1 m: Fang, Mae Fang NP, Doi Pha Hom Pok, 2000 m, along road and creek, 20. 11. 2003, leg. A. SZAPPANOS .

Loxocera sp. ( decora DE MEIJERE , or, humeralis DE MEIJERE, cf. DE MEIJERE 1914, 1916) – 1 m: PF04/11; 1 f: Vietnam, Da Lat, Cam Ly area, No. 691, 4. XII. 94, ZOMBORI. We are not sure of the identity of these specimens, but can state that they are not conspecific with any of the Japanese species ( IWASA 1992).

Pseudopsila nigricollis FREY, 1955 – 1 f (head in a plastic microvial with glycerol): PF04/10. This is an immature specimen, whose head was wrinkled. So the head was detached, boiled in NaOH, washed in water, in lactic acid and in water again and studied thereafter. We believe that this paper is not the proper place to discuss whether FREY’ s Burmese species really belong to this Nearctic genus (see also IWASA 1992); simply, we believe that this species is conspecific with FREY’ s.
