DROSOPHILIDAE

In the CDO ( OKADA 1977) 35 spp. in five genera were listed from Thailand: Amiota (Phortica) 1 sp., Drosophila (Dorsilopha) 1 sp., D. ( Drosophila ) 7 spp., D. ( Sophophora ) 22 spp., Liodrosophila 1 sp., Paramycodrosophila 1 sp., Sphaerogastrella 2 spp.

Of them, Drosophila (Sophophora) baimaii BOCK & WHEELER, 1972 (p. 70), D. (S.) barbarae BOCK & WHEELER, 1972 (p. 62), D. (S.) eugracilis BOCK & WHEELER, 1972 (p. 31), D. (S.) khaoyana BOCK & WHEELER, 1972 (p. 68), D. (S.) orosa BOCK & WHEELER, 1972 (p. 64), D. (S.) parabipectinata BOCK, 1971 (p. 277), D. (S.) paralutea BOCK & WHEELER, 1972 (p. 15), D. (S.) rhopaloa BOCK & WHEELER, 1972 (p. 69) and Sphaerogastrella rostralis OKADA, 1974 (p. 31) were described from Thailand.

After closing the manuscript for the CDO, OKADA (1977) described Amiota (Phortica) omega (p. 21, Doi Suthep ), BAIMAI (1979) described Drosophila bocki (p. 237, Khao Yai N.P.) of the D. kikkawai complex from Thailand. HIHARA & LIN (1984) described a new species, D. siamana (p. 207) of the Drosophila hypocausta group, whose paratypes are from Thailand. OKADA’ s papers on the Leucophenga proxima group (1987), his revision of Pararhinoleucophenga and Paraleucophenga (1988) and his revision of the Leucophenga ornata group (1990) contained records of species also from Thailand and he described Leucophenga kurahashii OKADA, 1987 (p. 91) and Paraleucophenga shimai OKADA, 1988 (p. 621). TODA’ s (1991) paper on Drosophila melanogaster group included records from Thailand. In their revision of the SE Asian Stegana (Oxyphortica) nigripennis species group CHEN & WANG (2004) described a species (S. (O.) prigenti) also from this country. OKADA (1980) described Hypselothyrea scutellata OKADA, 1980 (p. 508, Khao Yai N.P) and H. truncata (p. 507, Doi Suthep ), and there he published the first Thai record for H. guttata DUDA, 1926 and H. pseudoguttata TAKADA & MOMMA, 1975 . In another Hypselothyrea paper PAPP (2003) described H. deficiens L. PAPP, 2003 , H. paralanigera L. PAPP, 2003 ( Thaii holotypes), H. paratenuis L. PAPP, 2003 ( Thaii paratypes).

Our material is remarkable. It is not only numerous, but very rich in species, indeed. We captured 219 indiv. of Hypselothyrea spp. in 2004; Hypselothyrea is far more abundant in the Oriental region, than formerly expected. Our Hypselothyrea material includes nine or ten spp., incl. two new species of H. (Deplanothyrea) and a reduced-winged Hypselothyrea sp. n. In 2004 793 specimens, in 2003 344 specimens belonging to other genera were selected and pinned. Their identification must be the aim of another project.

Hypselothyrea (Deplanothyrea) formosana L. PAPP, 2003 – 4 m 1 f: PF04/1; 1 f: PF04/3; 8 m 8 f: PF04/8; 1 m: PF04/9; 1 m: PF04/10; 1 m: PF04/17; 1 m: PF04/19; 1 f: PF04/26. Described recently from Taiwan but its seems more widespread. The two new spp. of Deplanothyrea in our material are related to this species.

Hypselothyrea deficiens L. PAPP, 2003 – 1 f: PF04/1; 1 m 5 f: PF04/3; 2 m: PF04/7; 7 m 2 f: PF04/8; 3 m 5 f: PF04/11; 1 f: PF04/12; 1 m 1 f: PF04/19; 2 m 4 f: PF04/26; 1 m: PF04/27. It was described from Taiwan, but we are sure it is a more widespread Oriental sp. It is a sp. of the H. guttata species group, where details of the male genitalia are the reliable characters for separating species. In the original description of this species, the peculiar undulately bent costa (and wing) on second costal section, seemingly a specific character, was not properly stressed.

Hypselothyrea guttata DUDA, 1926 – 4 m 2 f: PF04/1; 1 m 1 f: PF04/3; 4 m 4 f: PF04/8; 4 m: PF04/10; 1 m 1 f: PF04/11; 1 m: PF04/14; 1 f: PF04/17; 1 m: PF04/26. This is the commonest Oriental sp. of the genus ( PAPP 2003).

Hypselothyrea paralanigera L. PAPP, 2003 – 1 m: Trang Prov., Thung Khai Botanic G., pasture, 13. 11. 2004, A. Orosz; 6 m 2 f: PF04/3; 1 f: PF04/7; 2 m 4 f: PF04/8; 1 f: PF04/10; 4 f: PF04/11; 1 m: PF04/12; 6 m 2 f: PF04/14; 1 m: PF04/19; 3 m 2 f: PF04/21; 13 m 11 f: PF04/25; 6 m: PF04/26; 2 m: PF04/27; 5 m: PF04/28; 9 m 2 f: PF04/29; 3 m 1 f: PF04/29a; 2 m: PF04/30; 1 m: PF04/35; 2 m: PF04/36; 4 m: PF04/38; 2 m 3 f: PF04/42 (102 indiv.). Although recently described, it is a rather common species in Thailand.

Hypselothyrea paratenuis L. PAPP, 2003 – 3 m: PF04/8; 2 f: PF04/11; 1 m: PF04/12. It was described from Vietnam and Thailand. Though it is not as common as the former sp., this beautiful (and easily identifiable) sp. must not be rare, since soon after the former original record, it is reported again from Thailand.

Hypselothyrea pseudoguttata TAKADA & MOMMA, 1975 ( H. paraguttata : PAPP 2003, lapsus calami) – 1 m: PF04/9; 1 m: PF04/42.
