DIAGNOSIS: Only pupa of Ceratopogonidae with the metathorax with only one campaniform sensillum (M-3-T) situated at least ⅓ the length of the metathorax from its anterior margin ( Fig. 54A ), apex of the halter extending posteriorly to about 1/6 length of tergite 2 (as in Fig. 33L ), abdominal segment 4 with V-5-IV, V-6-IV and V-7-IV closely approximated ( Fig. 70C ) or, if V-7-IV is closer to L-4-IV then L-3-IV is closer to L-2-IV than to an elongate L-1-IV (as in Fig. 69C ) (not as in Fig. 70B ), abdominal segment 8 has V-5-VIII and V-6-VIII on separate tubercles or if on partially to completely fused tubercles, then V-5-VIII is well-developed (not minute), and segment 8 is without L-1-VIII (not diagnosable as different from Bezzia and Phaenobezzia ); however, most species of Bezzia have two or more campaniform sensilla on the dorsal apotome ( Figs. 22C–D ), a nearly unique condition found otherwise only in P. flavipes and P. jonesi (the latter distinctively with two setae ( Fig. 22J ).

DISTRIBUTION AND HABITAT: The genus Palpomyia is known from 270 species from every Region worldwide ( Borkent 2014, additional species below). Immatures have been collected from streams, hot springs, river margins, marshes, bogs, fens, ponds, lakes and reservoirs.

TAXONOMIC DISCUSSION: There are 41 species of Palpomyia known as pupae ( Tables 2–3). Thienemann (1928), Mayer (1934a) and Lenz (1934) provided similar keys to a few European species groups known at that time. Grogan & Wirth (1979), in their masterful revision of Nearctic Palpomyia , provide a key to the pupae of 16 species known from the Nearctic. However, it is unfortunate that Palpomyia pupae cannot be diagnosed at the generic level so that we cannot yet identify a Palpomyia pupa as such. The key therefore requires foreknowledge that the specimen is a member of the genus (e.g. reared to adult).

Liu & Yu (1991) described the monotypic genus Nemoromyia Liu & Yu based on their newly described N. nemorosa Liu & Yu. They stated that the genus was a member of the Heteromyiini . Borkent (1998) indicated that the species was actually a species of Palpomyia based on various described features but that the type should be reexamined before nomenclatural changes are made. Yu et al. (2005) continued to place the genus and species in the Heteromyiini , although the evidence for this was unclear (it is not noted in the English abstract, but I have not translated the longer Chinese text). I have reexamined the female holotype and associated pupal exuviae and it is clearly a member of the Palpomyia distincta species group and, within this group, is very similar to P. rufa Loew ( Grogan & Wirth 1979) . The female has the characteristic synapomorphy of posteromedially directed lobes on sternite 8 of the P. distincta group. Furthermore, tergite 8 is very short (much shorter than tergite 7), a feature which is a synapomorphy of the Palpomyiini (the feature is unique in the Ceratopogonidae ), further supporting its position as a species of Palpomyia . The pupa of N. nemorosa is very similar to a number of other species of Palpomyia (as indicated in the key). Liu & Yu (1991) noted that the adult female lacked the abdominal tergal apodemes which is a synapomorphy of the Palpomyiini . However, as shown by Borkent & Craig (1994), newly emerged female adults of this group do not show the apodemes which sclerotize and darken after emergence. It is not surprising, therefore, that this reared specimen was reported as lacking the apodemes. I therefore recognize Nemoromyia as a new synonym of Palpomyia and the species as a new combination as follows:

Palpomyia nemorosa (Liu & Yu) , 1991: 26 ( Nemoromyia ). Raohe, Heilongjiang Province, China. new combination.

The pupa of P. lineata has been described more than once by the same authors ( Table 2) but with different names (now synonyms), suggesting either misidentifications or the possibility of more than one species actually being present in Europe.

Ronderos et al. (2004) gave a detailed description of the pupa of P. guarani . Their figure of the cephalothorax (their fig. 14) shows the apex of the halter extending only barely past the anterior margin of tergite 2. This would be unique within the Palpomyia + Bezzia + Phaenobezzia + Clastrieromyia + Stenoxenini clade, where the halter extends to about 1/6 the length of tergite 2. Paul et al. (2014) recently thoroughly described the pupa of a species from India, the first known from the Oriental Region, but misidentified some of the sensilla (e.g. SA-2-T, L-3-IV, L-4-IV).

DISTRIBUTION AND HABITAT: The genus Phaenobezzia is known from 34 species from every Region worldwide other than the Australasian Region ( Borkent 2014). Immatures have been collected from stream and river margins, seepage pools, rice fields, back waters of rivers, marshes (usually among vegetation), among Pistia stratiotes , lake margins and reservoirs. Knausenberger (1987) provides some further microhabitat information for P. opaca .

TAXONOMIC DISCUSSION: The pupae of nine species of Phaenobezzia are known ( Tables 2–3).

Haeselbarth (1965) used the shape of the terminal processes to distinguish the pupae of the four African species he studied and indicated some further character states which may separate some species. Thomsen (1937) drew the dorsal apotome of P. opaca with two setae (and no campaniform sensillum); she likely mistook the campaniform sensillum as the broken base of a seta. Wirth & Grogan (1982) drew abdominal segment 4 of P. opaca with V-7-IV situated laterally, close to L-4-IV and this is significantly different than that observed here for this species and all other Phaenobezzia ( Fig. 71B ).

DISTRIBUTION AND HABITAT: The genus Paryphoconus is known from 41 species in the Nearctic (one species) and Neotropical Regions ( Borkent 2014). Pupae have been collected among vegetation along creeks or on the sandy bottom of a shallow stream.

A female pupa of a Mallochohelea in the ZSMC was labeled " Paryphoconus lanei " but on a modern label and with recent handwriting. The specimen was among material studied by Mayer but does not correspond to his description of Paryphoconus flavidus (as lanei ) ( Mayer 1959b). The Paryphoconus pupae studied by Mayer (1959b) were not located.

DISTRIBUTION AND HABITAT: The genus Paryphoconus is known from 41 species in the Nearctic (one species) and Neotropical Regions ( Borkent 2014). Pupae have been collected among vegetation along creeks or on the sandy bottom of a shallow stream.

TAXONOMIC DISCUSSION: The pupae of four species of Paryphoconus are known ( Tables 2–3). A female pupa of a Mallochohelea in the ZSMC was labeled " Paryphoconus lanei " but on a modern label and with recent handwriting. The specimen was among material studied by Mayer but does not correspond to his description of Paryphoconus flavidus (as lanei ) ( Mayer 1959b). The Paryphoconus pupae studied by Mayer (1959b) were not located.

MATERIAL EXAMINED: P. grandis : 2 pupal exuviae, Ruta Nacional 12, Corrientes, Argentina, 18-IX- 2010 ( MLPA). P. oliveirai : 1 pupal exuviae, Parque das Garcas, Amazonas Igarape, Brazil, 14-X-2005 ( INPA) .
