Papp, L.: A review of the Old World Trigonometopini Becker (Diptera: Lauxaniidae)

Kerteszomyia MALLOCH, 1929 Kerteszomyia MALLOCH 1929: 39,35. Type species: Trigonometopus maculifrons MALLOCH, 1929 (monotypy). Remarks - MALLOCH (1929) based the genus on a single species from the Philippines (Luzon). STUCKENBERG (1971) reported on an undescribed species from New Guinea. I did not find any specimens during this project, which would fit to the generic concept. However, Maquilingia thaii sp. n. with its very strong peristomals resembles MALLOCH's (1929) fig. 29 (for details see below). Maquilingia materna CURRAN, 1936 is also similar in this respect. Luzonomyza MALLOCH, 1929 Luzonomyza MALLOCH 1929: 34. Type species: Trigonometopus bakeri BEZZI, 1913 (monotypy). Luzonomyza bakeri (BEZZI, 1913) - The type of this species was not seen during this project. However, I think, its identity can be judged by the figure of its genitalia (MALLOCH 1929: fig. 28). In order to make easier its use that was re-drawn as Fig. 6. Luzonomyza japonica (SASAKAWA, 2002) (Trigonometopus (Luzonomyia)). - It was described from the Ryukyus (Amami-Oshima) (SASAKAWA 2002). This is a species with male epandrium without dorso-caudal appendages. Although it was not found during this project, I was able to fit it properly in the key below. Luzonomyza nigripalpis (SHATALKIN, 1997) (Trigonometopus (Tetroxyrhina)) - Material studied: 1 male: Thailand, Trang Prov., Khao Chong Botanic Garden, rainforest, Nov 18, 2004, No. 36, leg. L. PAPP & M. FÖLDVÁRI; 1 female: ibid., Nov 22, No. 43 (cf. PAPP et al. 2006). It was described from Khao Sok, based on a single male. I hope I was able to recognise it properly. As SHATALKIN said, its male epandrium is with "short, nipple-shaped lobes". Luzonomyza pseudoforficula sp. n. (Figs 7-10, 66) Type material - Holotype male (HNHM): "Thailand Trang Prov., Thung Khai Botanic Garden, primary lowland rainforest on "Nature Trail", Nov 13, 2004, No. 29, leg. L. Papp & M. Földvári". A freshly emerged (teneral) specimen, right wing strongly wrinkled, left wing prepared between two small pieces of cover glass, head (otherwise intact) glued under the specimen. Description - Measurements in mm: body length 3.41, wing length 3.23, wing width 1,12. This is one of the smallest species of the genus. Black spot between eye and antennái base small.
