In the keys of Lundbeck (1922) for Group VII it runs to options covered by the following key to the males of species from the British Isles (Disney, 1989) where it runs to triplet 218, but their hypopygia clearly differ. Alternately it will run to couplet 158, but this couplet has been replaced by a revision of this complex (Buck &amp; Disney, 2001) in which it fails to key out. In Borgmeier’s (1966) key to Nearctic Group VIII it runs to species covered by the key to British species. It fails to run down in keys for the rest of the world’s fauna and their subsequent additions.</p> <p>Description. Male. Frons as Fig. 12, without microtrichia except at edges (Fig. 13).

In the key of Lundbeck (1922) to Group VI it runs to couplet 7 lead 1 M. longiseta (Wood) which is immediately distinguished by its distinctive hind femur. An uncommon feature of our species is the left hypandrial lobe is vestigial but the right lobe is well developed. In the key to the males of species from the British Isles (Disney, 1989) it runs to couplet 256 where lead 1 almost applies but the figures of the hypopygia referred to rule out this option. Lead 2 proceeds to couplet 258 lead 2, but is ruled out as it has 3 not 2 notopleural bristles. However, a note says if neither lead applies proceed to couplet 264, where lead 1 proceeds to couplet 265 and thence via lead 1 to couplet 266, where lead 1 is excluded by its hypopygium. Proceeding to 267 both options are excluded by their hypopygia, and by the number of notopleural bristles or the extent of vein Sc. Of excluded species M. intergeriva Schmitz runs to couplet 258, but its hypopygium clearly differs (Fig, 4 in Disney, 2011a). It fails to run down in keys for the rest of the world’s fauna and subsequent additions.</p> <p>Description. Male. Frons as Figs 25 and with the very fine microtrichia extending all over, and the upper SAs being a little further apart than the pre-ocellars. Cheek seemingly with a single bristles and jowl likewise but it is longer and more robust. The postpedicels, which lack SPS vesicles, palps and proboscis as Fig. 26. Labella with about 20 short spinules below each (Fig. 27). Thorax brown. With 3 notopleural bristles and no cleft in front of these. Mesopleuron bare. Scutellum with an anterior pair of small hairs and a posterior pair of bristles. Abdomen as Fig. 28, with tergite hairs a little longer at rear of T6 and venter with hairs on segments 3–6. Hypopygium as Figs 29–31, with the anal tube more than 1.5 times as long as the dorsal face of the epandrium. Legs yellowish to yellow. Fore tarsus (Fig. 32) with posterodorsal hair palisade on segments 1–5 and 5 longer than 4, and basitarsus with 2 rows of hairs reduced to small spinules. Dorsal hair palisade of mid tibia extends about 0.65 times its length. Hairs below basal half of hind femur longer than those of anteroventral row of outer half. (Fig. 33). Hind tibia with a dozen differentiated posterodorsal hairs, without anterodorsals, and spinules of apical combs simple. Wings (Fig. 34) 1.20 mm long. Costal index 0.46. Costal ratios 3.4: 1.8: 1.

In the key of Lundbeck (1922) to Group I it runs to couplet 31 but both species are covered in the key to the males of the British species (Disney, 1989) where it runs to couplets 159 and 160. However, this complex was revised by Buck &amp; Disney (2001) in which it runs to couplet 11 lead 1, where its hypopygium differs from both options. The subsequently described M. fallobreviseta Disney (2011e) runs to the same point. It has paler wings and the labella of the proboscis lack spinules below. In the key of Schmitz &amp; Delage (1981) it runs to couplet 38 lead 1, both species being covered by Buck &amp; Disney’s revision. Of two other species running the same point one has a yellow thorax and the other brown Halteres.

Two notopleural bristles and no cleft in front of these, and mesopleuron bare (Fig. 52). Scutellum with 4 bristles that are subequal in length (Fig. 53). Abdominal tergites brown with moderate hairs that a little longer at rear of T6 (Fig. 54). Venter gray, and with hairs on segments 3–6. Hypopygium as Figs 54–56, the pale hypandrial lobes are subequal in length and with microsetae. Hind legs brown and the rest progressively yellowish to yellow. Fore tarsus (Fig. 57) with posterodorsal hair palisade on segments 1–5 and 5 longer than 4. Dorsal hair palisade of mid tibia extends about 0.67 times its length. Hairs below basal half of hind femur clearly longer than those of antero-ventral row of outer half (Fig. 58).

In the keys of Lundbeck (1922) it runs to Group VI couplet 17 lead 1 M. minor (Zetterstedt). However, this was a misidentification of M. minuta (Aldrich) (Disney, 1984), which is immediately distinguished from our species by its notopleuron having only 2 bristles and a notopleural cleft. With the costal index being 0.44 one needs to check whether it keys out in Group VII, where it runs to couplet 15, where neither option fits. In the key to the males of the British species (Disney, 1989) it runs to couplet 232 where one is returned to couplet 194 and thence to couplet 226, where one is returned to couplet 232! Of the additional species running to this couplet 4 have clearly different hypopygia along with brown hind femora and/or postpedicels with SPS vesicles and/or a costal index exceeding 0.5. A further 2 are considered below. In Borgmeier’s (1966) key to Nearctic species of Group VII it runs to couplet 12, where neither option fits. In his key to Group VIII it runs to couplet 10 lead 1 M. bovista (Gimmerthal). However, Borgmeier misidentified M. agarici (Lintner) as this species, and prior to the description of the male of M. abdita Schmitz (under its synonym M. griseipennis Santos Abreu) (Disney, 1987, ICZN, 2012), these two species were being confused. Furthermore, the similar Nearctic M. agarici and Arabian and Oriental M. sandhui Disney had also been confused (Disney, 2008). The male of M. sandhui has a curious ‘pocket’ on its abdominal venter. M. abdita has brown hind femora whose basal hairs are shorter than the anteroventral hairs and a different hypopygium with a shorter anal tube. Our species fails to run down in keys for the rest of the world’s fauna and subsequent additions.</p> <p>Description. Male. Frons as Fig. 61, with microtrichia absent except at extreme margins, but with more than 80 hairs. The upper supra-antennal bristles are further apart than the pre-ocellars. Cheek with 3 bristles and jowl with 2 that are longer and more robust. Postpedicels, without SPS vesicles, palps and proboscis as Fig. 62, the labella with only a few short spinules below. Thorax brown. With 3 notopleural bristles and no cleft in front of these (Fig. 63). Mesopleuron bare. Scutellum with an anterior pair of hairs and a posterior pair of bristles (Fig. 64).Abdomen as Fig. 65, the venter with hairs on segments 3–6. Hypopygium as Figs 66–69. Legs yellowish. Fore tarsus (Fig. 70) with posterodorsal hair palisade on segments 1–4. Dorsal hair palisade of mid tibia extends about 0.66 times its length.

In the keys of Lundbeck (1922) it runs to Group IV couplet 38, or Group V couplet 12 lead 2, it fits none of the options. In the key to the males of the British species (Disney, 1989) it runs to couplets 81 lead 2 or 143, but the hypopygium differs from these species. Other excluded species running to these points have different hypopygia, apart from other details such as possession of SPS vesicles in the postpedicels and/or very pale wings. In the keys of Schmitz &amp; Beyer (1965) for Abteilung IV Zweite Reihe it runs to couplet 53 but again the hypopygium differs and the palps are darker. In the keys of Schmitz &amp; Delage (1974) for Abteilung V it runs to couplet 35 lead 1 or couplet 82 lead 1, but the hypopygia of these species differ (being figured by Disney, 2003 and 2011c). It fails to run down in keys for the rest of the world’s fauna and subsequent additions. It should be noted that the front basitarsus looks broader in one orientation but narrower in another orientation.</p> <p>Description. Male. Frons as Fig. 82, with the fine microtrichia restricted to the edges and adjacent to the median furrow. Cheek with 3–4 bristles and jowl with 2 that are clearly longer and more robust. Postpedicels, without SPS vesicles (Fig. 84), palps and proboscis as Fig. 83. Thorax as Fig. 85, having 3 notopleural bristles and no cleft in front of these, the mesopleuron with hairs and the scutellum with an anterior pair of small hairs and a posterior pair of bristles. Abdominal tergites brown with small hairs that are scarcely longer at the rear of T6. Venter gray, and with hairs on segments 3–6. Hypopygium as Figs 86–91, the epandrium with small hairs only, the pale left lobe of the hypandrium being large and with long projecting microtrichia but the right lobe being vestigial. Legs light brown to dusky yellow. Fore tarsus with posterodorsal hair palisade on segments 1–5 with 5 longer than 4 (Fig. 92) and the basitarsus with rows of spinules below (Fig. 93). Dorsal hair palisade of mid tibia extends 0.62–0.67 times its length (Fig. 94). Hind femur as Fig. 95. Hind tibia with about two dozen moderately differentiated posterodorsal hairs, without anterodorsals, and spinules of apical combs simple. Wings (Fig. 96) 1.40–1.61 mm long. Costal index 0.43–0.48.

This species was described from a single male from Poland. It closely resembles M. nigrescens (Wood). Indeed, the hypopygia are very alike. Unfortunately, the front legs of the holotype were damaged and only the incomplete front tarsus of one leg remained. The specimens from Denmark allow a clearer distinction. Thus, the fore tarsus of M. nigrescens has posterodorsal hair palisades on segments 1 to 4 only (Fig. 172); whereas in M. nigricia they are present on all five segments (Fig. 171). In addition, the postpedicels of M. nigrescens lack SPS vesicles (Fig. 170) but are present in M. nigricia (Fig. 169).</p> <p>Material examined. Denmark, 2 males, Tofte Mose, 13–24.

In the key of Lundbeck (1922) for Group VII it runs to couplet 22 lead 1 M. maura (Wood), but it has a different hypopygium with well developed hypandrial lobes. In the key to the males of the British species (Disney, 1989) it runs to couplet 263 lead 2 top M. maura or couplet 225 lead 1 M. sptemtrionalis (Schmitz). However, the latter having been described from the female only, recognition of this species gave rise to confusion prior to augmentation of its description by Buck &amp; Disney (2001) and the male previously attributed to this species being recognized as the new species M. labellaspinata Disney. It has a different hypopygium, a costal index exceeding 0.45, posterodorsal hair palisades on all five joints of the front tarsus and postpedicels with SPS vesicles. Subsequently 5 added species running to these couplets, apart from their different hypopygia, differ in one or more of the following featuresposterodorsal hair palisades on all five segments of the front tarsus, postpedicels with SPS vesicles, 3 notopleural bristles, costal index exceeding 0.43. In Borgmeier’s (1966) key to Nearctic Group VIII it runs to couplet 15 lead 2 M. pygmaeola Borgmeier, which has very short microsetae on its antennal aristae and very weak posterodorsal hairs on the hind tibiae. Our species fails to run down in keys for the rest of the world’s fauna and subsequent additions.</p> <p>Description. Male. Frons as Fig. 173, with dense but very fine microtrichia all over and upper supra-antennal bristles further apart than the pre-ocellars. Cheek with 4 bristles and jowl with 2 that are longer and more robust. Antennae, palps, proboscis as Fig. 174, the labella having short spinules below (Fig. 175). Thorax brown, with 2 notopleural bristles and no cleft in front of these, and mesopleuron bare (Fig. 176). Scutellum with an anterior pair of small hairs and a posterior pair of bristles. Abdominal tergites and venter as Fig 177, the venter having small hairs on segments 3–6. Hypopygium as Figs 178, 179, 239 &amp; 240. The hypandrial lobes being vestigial. Legs yellowish brown to pale yellow. Fore tarsus (Fig. 180) with posterodorsal hair palisades on segments 1–4 and 5 longer than 4 and 5 a little darker. Dorsal hair palisade of mid tibia extends about 75 times its length. Hairs below basal half of hind femur longer than those of anteroventral row of outer half (Fig. 181).

In the key of Lundbeck (1922) for Group VII it runs to couplets 27 and 28, but none of the options fit. In the key to the males of the British species (Disney, 1989) it runs to couplets195 lead 1 M. tarsella (Lundbeck) and 253 lead 2 M. uliginosa (Wood). The costal index of both species exceeds 0.46 and they differ in their hypopygia and other details. Subsequent additions are also ruled out. In Borgmeier’s (1966) key to Nearctic Group VIII it runs to couplet 10 lead 1 to his misidentified M. bovista (Gimmerthal), see above under M. falloclavis n. sp. Of this confusion of species only M. abdita Schmitz needs consideration here. It is readily distinguished by its hypopygium, brown Haltere and the hairs below the basal half of the hind femur being shorter than those of the anteroventral half. Our species fails to run to any species in the rest of the world’s fauna. Apart from other details a distinctive feature that excludes most species is segment 5 of the mid tarsus being about 1.3 times longer than segment 4. Most species of Megaselia have segment 4 longer than 5. The subcosta of our species appears to end before reaching vein R 1 in one focus but seems to reach it in another focus (cf Figs 197–198). However, where the distinction is used in the key to British species at couplet 187 a note adds that variable species are keyed both ways. Indeed both routes lead to M. tarsella (see above).</p> <p>Description. Male. Frons as Fig. 183, with microtrichia restricted to margins. Cheek with 4 bristles and jowl with 2 that are much longer and more robust. Postpedicels pale brown, without SPS vesicles (Fig. 185), and as Fig. 184. Palps and proboscis as Fig. 184, the labella with only a few short spinules below. Thorax brown, with 3 notopleural bristles and no cleft in front of these, and mesopleuron bare (Fig. 186). Scutellum with an anterior pair of small hairs and a posterior pair of bristles (Fig. 187). Abdomen as Fig. 188, the pale venter with hairs on segments 3–6. Hypopygium as Figs 189–191, there being no right hypandrial lobe and the cerci being 2.4–2.5 times as long as their breadths. Legs yellowish to even paler. Fore tarsus with posterodorsal hair palisade on segments 1–5 and as Figs 192 and 193. Dorsal hair palisade of mid tibia extends about 79 times its length. Mid tarsus with segment 5 about 1.3 times the length of 4 (Fig. 194). Hairs below basal half of hind femur longer than those of anteroventral row of outer half (Fig. 195).

In the key to the males of the British species (Disney, 1989) it runs to couplet 107, lead 2 M. consetigera (Schmitz), but it has brown Halteres, a different hypopygium and longer hairs below the basal half of the hind femur. Other species running to this couplet include M. subnitida (Lundbeck), rescued from synonymy by Disney &amp; Häggqvist (2018), but it’s hypopygium has a much longer left hypandrial lobe and longer hairs below the basal half of the hind femur. In the key of Schmitz &amp; Beyer (1965) for Abteilung IV Zweite Reihe it runs to couplets 60 lead 2 or 65 lead 1 or 78 lead 2 but all these options are excluded in the key to the males of the British species. Otherwise the most similar Palaearctic species is M. tofteensis described below.

In the key of Lundbeck (1922) for Group IV it runs to couplet 40 M. setigera (Lundbeck), a synonym of M. brevifemorata Schmitz, from which it differs in having only 2 notopleural bristles, SPS vesicles in the postpedicels, 6 axillary bristles and a different hypopygium. In the key to the males of the British species (Disney, 1989) it runs to couplet 107 lead 1 M. consetigera (Schmitz) but our species has a longer anal tube and 5–6 axillary bristles. In the key of Schmitz &amp; Beyer (1965) for Abteilung IV Zweite Reihe it runs to couplet 60 lead 2, M. brevifemorata Schmtz, but it has a brown hind femur, 6 axillary bristles and 3 bristles on the notopleuron; or it runs to couplet76, lead 1 M. subpalpalis (Lundbeck), already excluded in the key to the males of the British species. In Borgmeier’s (1964) key for Nearctic Group IV it runs to couplet 16 lead 1 M. subpleuralis (Wood), which is covered by the above keys but is immediately excluded by having 3 notopleural bristles and the hairs below the basal half of the hind femur shorter than those of the anterovental of the outer half. In the in the key to the species of the Seychelles (Disney, 2009) it runs to M. falsoluta Disney, but its mesopleuron has 1–3 bristles as well as hairs and much larger labella of the proboscis. It most closely resembles M. simestedensis described above. It differs in having only 2 bristles on the notopleuron, a longer wing but shorter costal index, a dorsal hair palisade on all five segments of the front tarsus, instead of 1–4 only, longer hairs below the basal half of the hind femur and a much longer left hypandrial lobe. Otherwise it fails to run down in keys for the rest of the world’s fauna and subsequent additions. We should add, that M. tofteensis at first sight appears exactly like a species of the giraudii/ densior complex (definition see Buck &amp; Disney p 75) with the long hairs on protiger and well developed left and right hypandrian lobe. Even the shape of epandrium suggests the giraudii/ densior complex. But as tofteensis has hairs (although only 2–3) on mesopleuron it is not included in this species complex.</p> <p>Description.
