Immatures are known from stream and river margins, lakes and ponds. Knausenberger (1987)discusses the various habitats in which  A. atripeswas collected in the eastern USA. At least some pupae were on emergent vegetation (although they do not have abdominal membranous discs).   TAXONOMIC DISCUSSION: Pupae are known from two species ( Tables 2–3). All the species placed here in the new genus  Anebomyiawere previously in  Mallochohelea. The new genus is recognized because the newly included species are not related to those now restricted to  Mallochohelea, a genus most closely related to  Jenkinshelea,  Macropeza,  Probezziaand  Neobezzia(see phylogenetic analysis below, Fig. 81).  There are differences between the two genera in both male and female adults and in pupae, with most of the adult features not yet interpreted cladistically (but see character 85). They are summarized as follows:     Anebomyia   Mallochohelea  male parameres separate parameres fused    female with at least forefemur with one or more spines femora generally without spines (one species with spines)  female without strong tufts on sternite 8  femalewith strong tufts on sternite 8  pupal dorsal apotome with 4 tubercles dorsal apotome with 2 tubercles  pupa with two elongate anteromedial setae one elongate anteromedial seta  pupal ecdysial split between eye and antenna ecdysial split on eye  pupal D-5-T elongate seta D-5-T short, peg-like  pupal D-2-1 and D-3-1 close together D-2-1 and D-3-1 widely spaced  pupal abdominal sternites without membranous discs abdominal sternites 6, 7 with membranous discs  Knausenberger (1987: 267-277)provided further differences between the two genera (as  albibasisand  atripesgroups), including a larval feature. His information was based on Nearctic species and the character states need further testing with extraterritorial material. As indicated above, members of  Anebomyiadiffer from true  Mallochoheleaby the absence of distinctive tufts of elongate setae on sternite 8 of female adults. In  A. atripes, elongate setae are absent. In  A. flumineathere are elongate setae on sternite 8 but these are not arranged as a tight tuft (as is true in  Mallochoheleaand other related genera; see character 85). Examination of female adult  M. texensisindicates that it too lacks a well defined sternite 8 tuft.  Wirth (1962), in erecting  Mallochohelea, pointed out that some of the included species such as  M. atripes,  M. spinipesand  M. texensisdiffered considerably from the genotype (  M. albibasis) and "may, eventually need a separate category". He further pointed out in a strikingly prescient statement "The discovery of the pupa of this group should also serve greatly to clarify its relationships". The pupae have indeed provided the synapomorphies to clarify the relationship of these species. Although Wirth (1962)considered  M. spinipesas closely related to  A. atripes, I have not included it in  Anebomyia. I have not examined material of this species and know only that the adult female has spines on its femora; the sternite 8 tufts are not described and the male remains unknown. Like this and a number of other species presently in  Mallochohelea, reexamination of specimens is needed before the names are potentially transferred to the new genus. Of course, knowing the pupae of further species will certainly clarify their taxonomic position. All European species of  Mallochoheleafit the characterization of this genus (Patrycja Dominiak, pers. comm.). The female of the European/Asian species  M. tianshanica, however, has spines on the femora and welldeveloped sternite 8 setal tufts (Patrycja Dominiak, pers. comm.) and the male has basally fused parameres ( Remm 1980). This suggests that  M. tianshanicais a true  Mallochoheleabut is the only species known with femoral spines. Debenham's (1974)description of  Mallochoheleaand the included Australian species suggests that they all actually belong within  Mallochohelea. The presence of femoral spines on the Afrotropical species  M. kirki( de Meillon & Wirth 1981)may indicate they are members of  Anebomyiabut the presence or absence of the female sternite 8 setal tufts is unknown and males are undescribed, making its placement uncertain. The African species  M. siricishas a female with spines on the forefemur and the male has separate parameres; although the condition of the female sternite 8 seta tufts is uncertain, I consider this sufficient evidence to place it in  Anebomyia. The Chinese species  M. yunnana, known only as a female, has femora spines and lacks the sternite 8 setal tufts, indicating it too is an  Anebomyia.   Included species:    Anebomyia atripes(Wirth), 1962: 281(  Mallochohelea). Typelocality: New Brunswick, New Jersey, USA. new combination.   Anebomyia fluminea(de Meillon & Wirth), 1981: 550(  Mallochohelea). Typelocality: Sand River between White River and Hazyview, E.
