Abstract. The New Guinean fauna of Anthomyiidae was never considered before. It is represented by the genus Anthomyia. Previous data on the New Guinean Anthomyia are discussed. A. acklandi sp. nov. from highlands (above 3300 m) of New Guinea is described. The male of A. fumipennis Stein, 1919, previously known from a single female, is described. The widespread A. illocata is newly reported for Papua Province of Indonesia. The identification key for New Guinean Anthomyia is offered.

Аннотация. Фауна Anthomyiidae Новой Гвинеи, которая представлена родом Anthomyia, никогда ранее не изучалась. Обсуждены литературные данные по Anthomyia Новой Гвинеи. С высокогорий острова (выше 3300 м над уровнем моря) описан новый вид A. acklandi sp. nov. Дано описание самца A. fumipennis Stein, 1919, ранее описанного по единственной самке. Широко распространенный вид A. illocata впервые приведен для индонезийской провинции Папуа. Предложен определительный ключ для новогвинейских Anthomyia.

Introduction
The only species of Anthomyiidae reported for New Guinea was Anthomyia fumipennis Stein, 1919, described from a single female from Irian Jaya (presently Papua Province of Indonesia), Hellwiggeb, 1700 m. (The exact type locality is difficult to establish. Hellwiggeb is the river with its mouth at 5.35°S 137.88°E. The sources of this river are located in the Maoke Mountains, the height of 1700 m is located approximately here: 4.2°S 138.2°E.) The holotype was not found in Museum fur Naturkunde, Berlin (Pont, Ackland 2009).
This species was shortly discussed by Ackland (1987: 40): "The position of Anthomyia fumipennis Stein, described from New Guinea (not included in this paper) is problematical. It is a typically black and grey patterned fly and has hairs on the propleuron [= proepisternum here]. But the genitalia are more primitive in structure; the surstyli are simple and without stronger inner setae, the cercal plate is without specialised flattened apical setulae... sternite V is without a ventrally directed membranous lobe. Two further as yet undescribed species from New Guinea show even further divergence from typical Anthomyia species in structure of head and general appearance, but possess all the above characters offumipennis.'.'
In my opinion, non-genitalic characters like the scutal pattern and setulose proepis-ternum are much better for generic diagnosis than the structure of the male genitalia which is applicable only to males. It is also worth noting that in Australian/Oceanian region (Pont 1996) only genus Anthomyia is widespread. Thus, I consider New Guinean species as belonging to Anthomyia unless molecular data prove otherwise. Ackland (1987) wrote further on following: "These [undescribed] species are probably closely related, forming a monophyletic group which perhaps has been isolated for some considerable time. These species will be dealt with in a later paper." However, no description of any species of Anthomyia from New Guinea has been published by Ackland. I collected a large series of
A. fumipennis and an undescribed Anthomyia from New Guinean highlands. With this advantage, I would like to clarify the situation somewhat.

Holotype S: INDONESIA, Papua prov., Lake Habbema, 3350 m, 4.14°S, 138.71°E, 19-26.12.2014, N. Vikhrev. Paratypes: the same locality, 19-26.12.2014, N. Vikhrev. 13S, 6?; 10-12.12.2017, N. Vikhrev, 3S 3?. The entire type series is deposited in Zoological Museum of Moscow University (= ZMUM). Description. Head. Eyes bare, distance between eye margins at narrowest part slightly narrower than width of postpedicel (Fig. 2). Fronto-orbital plates at posterior 2/3 black and narrow, at anterior 1/3 grey and widened, with 3 pairs of inclinate setae on anterior 1/3. Frons narrow, yellowish-grey, with rather strong crossed interfrontals. Parafacials grey, with dark spots at upper and lower thirds. Mouthedge slightly protruding. Cheek about 1.5x as wide as width of postpedicel. Postpedi-cel 2.25x as long as wide. Longest aristal hairs slightly longer than basal diameter of arista. Proboscis elongated (Fig. 1), about 2/3 as long as fore tibia.
Thorax densely grey dusted over dark ground-colour; with contrasting black pattern on dorsal surface. Presutural area of scutum with a pair of rectangular black spots merged in front and diverging posteriorly (Fig. 2); postsutural area with black transverse band from suture to almost level of 3rd post dc (Figs. 1, 2). Scutellum black with only extreme apex pale, with setulae on ventral side. Black colour is not extended on pleura (darkening of anepisternum on Fig. 1 is a result of reflection). 2 + 3 dc; 3 pairs of presutural ac in rows separated by more than distance from each to adjacent dorsocentral row, without additional setulae in between. Prealar seta as strong as posterior notopleural; katepisternals 2 + 2,

lower posterior weak; proepisternum with 5-6 fine setulae. Wing with costal basal marginal spinules strong; anterior margin of wing darkened.
Legs dark. t1 with 1 pv and 1 ad; t2 with 1 ad, 2 pd and 1 pv; t3 with 1 av, 3 ad, 2 pd, 4-5 fine short pv at middle.
Abdomen grey dusted, tergites 1 + 2 to 5 with tridental black marks, less distinct on tergite 1 + 2 (Fig. 3). Surstyli elongated, widened in middle, with pointed apex; without stronger inner setae, cercal plate without specialised flattened apical setulae (Fig. 4); sternite 5 with a pair of strong apical setae (Fig. 5).
Female similar to male except for wide frons (40% of head width) and shape of abdomen, which is pointed at the tip. Diagnosis. A. acklandi sp. nov. has thorax with typical "Anthomyia-pattern" and setu-
lose proepisternum. It clearly differs from all Asian Anthomyia by presutural area of scutum with a pair of rectangular black spots merged in front and diverging posteriorly. Male has widened frons and simplified structure of genitalia.
