03B05940FFADFFA1FF50FD9BFB37D794.taxon	description	In the generic diagnosis for the adult, Roback (1971: 354) and Murray & Fittkau (1989: 42) wrote, “ third palpal segment shorter than second. ” Their second and third palpal segments correspond to the third and fourth palpomeres, respectively, in this paper. The adults of A. (Ablabesmyia) bifurca sp. n. and A. (Karelia) kisanganiensis Lehmann, 1981 (q. v.) have the fourth palpomere being distinctly longer than the third. In the adults of A. (Ablabesmyia) huananensis sp. n. and A. (Karelia) daiensis sp. n., the third palpomere is nearly equal to the fourth in the length. Thus, the character is qualified with “ usually ” for the generic diagnosis. Murray & Fittkau (1989) used the costal vein ending above the tip of M 3 + 4 as a discriminator separating the subgenus Sartaia from the subgenera Ablabesmyia and Karelia, but the wing venations of A. (Ablabesmyia) huananensis sp. n. and A. (Ablabesmyia) praegracilis sp. n. described here, as well as Ethiopian A. (Ablabesmyia) rimae Harrison, 1991 (q. v.), resemble that of A. (Sartaia) metica Roback, 1983. Oliveira et al. (2008) reared the larvae of A. (Sartaia) metica to describe the immature stages of the monotypic subgenus Sartaia. They (l. c. p. 62) noted as the diagnostic features for the pupa, “ It can be separated from other Ablabesmyia species in having shagreen on abdominal tergites consisting of simple spines and thoracic horn with dense, fine, oval-type of reticulation. ” However, the pupae of Chinese A. (Ablabesmyia) pectinata sp. n. and Ethiopian A. (Ablabesmyia) rimae also possess abdominal tergal shagreen consisting of simple spines. In Oliveira et al. (l. c.), the pupa of the Chinese species will key to Ablabesmyia s. str. by the thoracic horn apically with a nipple covering a club-shaped aeropyle tube. Harrison (1991: 58) stated that in the Ethiopian species, “ The pupal thoracic horn resembles that of A. (Asayia) annulata (Say), specially in the structure of the sub-apical position and structure of the horn sac neck, but the thoracic comb tubercles and the simple shagreen spinules are unlike those of annulata. ” Consequently, the Ethiopian pupa will key to Sartaia in Oliveira et al. (l. c.). Niitsuma (2013: 496) pointed out that a club-shaped aeropyle tube occurs not only in Ablabesmyia s. str. and Sartaia, but also in Karelia. According to Oliveira et al. (2013), in Neotropical A. gessnerae Neubern, the male has separate dark spots on the wing membrane, no setal tuft on the abdominal tergite VIII and an apically expanded sub-terminal seta on the gonostylus, of which combination is distinctive in Ablabesmyia s. str. (Murray & Fittkau 1989: 43), and the pupa possesses a T-shaped aeropyle tube on the apex of the thoracic horn, which is proper to Karelia (Oliveira et al. 2008: 66). Further, there is another problem between the adult and larva. In Neotropical A. ducke Neubern, A. fazzari Neubern and A. fusariae Neubern, as well as A. gessnerae, the male possesses the features as mentioned above, wing with separate spots, abdominal tergite VIII without lateral setal tufts, and gonostylus with an apically expanded sub-terminal seta, and the larva has two-divided maxillary palpi, a ligula with a concave margin of five pointed teeth and seven apical setae on the procercus (Oliveira et al. 2013). Thus, the males key to Ablabesmyia s. str. in Murray & Fittkau (1989: 43), whereas the larvae key to Karelia in Cranston & Epler (2013: 62). Although Oliveira et al. (2013) described 24 new species of this genus from the Neotropical region, they could not place these species on any subgenus. Therefore, the boundary between subgenera is still unclear.	en	Niitsuma, Hiromi, Tang, Hongqu (2019): Taxonomic review of Ablabesmyia Johannsen (Diptera: Chironomidae: Tanypodinae) from Oriental China, with descriptions of six new species.

03B05940FFAEFFA1FF50FCF0FB29D1B4.taxon	discussion	Remarks. Niitsuma (2013: 486, fig. 17) mistook the lateral lobe (LL) for the lateral filaments (LF) in the redescription of this species. Actually, the lateral filaments merge with the lateral lobe, and are not visible in the dorsal view. The male is characterized by the three wing spots located at the apices of R 1, R 3 and R 4 + 5, the weak basolateral bulge on the gonocoxite (Fig. 1 A; Kobayashi & Kubota 2002, fig. 14), the robust finger-like aedeagal blade and the well-developed dorsal lobe with an apical brush in the aedeagal complex (Figs 1 B, C). Niitsuma (l. c. p. 487) pointed out the similarities between the aedeagal complexes of A. (A.) prorasha and A. (A.) basalis (Walley). In the Chinese material, the male also resembles that of A. (A.) basalis in possessing dark brown abdominal segments VI – VIII, as described by Roback (1971, fig. 608). However, the hypopygium of the latter can be separated by the gonocoxite with a stronger basolateral bulge (cf. Roback 1971, fig. 607; Saether 2011, fig. 8 F). To date, the species has been recorded from Palaearctic Japan and Korea (Kobayashi & Kubota 2002; Niitsuma 2013). The Chinese collection shows that the distribution of the species extends to Oriental China.	en	Niitsuma, Hiromi, Tang, Hongqu (2019): Taxonomic review of Ablabesmyia Johannsen (Diptera: Chironomidae: Tanypodinae) from Oriental China, with descriptions of six new species.

03B05940FFAEFFA7FF50F8F7FD8ED624.taxon	discussion	Remarks. The everted aedeagal complex (Fig. 2 A) clearly shows the shape of the lateral lobe, which is a palmate membranous lobe and looks like a broad lanceolate membrane with lateral or apical teeth in normal position (Niitsuma 2013, fig. 28). Wang (2000: 631) recorded a larva of Ablabesmyia longistyla (Fittkau) from Liaoning Province in Palaearctic China. After the reexamination of the material, the second author suspected that it may be the larva of A. (A.) amamisimplex, because the basal segment of maxillary palp is sub-divided into four parts and the basal segment of antenna is more than 15 times as long as the basal width, which are consistent with description given by Niitsuma (2013). Indeed, A. (A.) amamisimplex is common in Palaearctic Japan and has been misidentified as A. (A.) longistyla by Japanese authors, Sasa et al. (1998), Kobayashi & Kubota (2002) and Niitsuma (2005). Although the species has been known from Palaearctic and Oriental Japan (Niitsuma 2013), we add new distribution records in Oriental China.	en	Niitsuma, Hiromi, Tang, Hongqu (2019): Taxonomic review of Ablabesmyia Johannsen (Diptera: Chironomidae: Tanypodinae) from Oriental China, with descriptions of six new species.

03B05940FFA8FFA7FF50FE7AFE33D331.taxon	discussion	Remarks. The species has been known only from Palaearctic Japan (Sasa & Okazawa 1991, Niitsuma 2013). Here, we record the distribution in Oriental (Fujian and Yunnan Provinces) and Palaearctic (Hubei and Anhui Provinces) China, based on the male specimens possessing a dorsal lobe with an apical brush, a curved blade with a pointed apex, and a lateral lobe with apicomedial serration in the aedeagal complex (Fig. 2 B), and the pupal specimens possessing darkened pattern on the abdominal tergites II – VIII (Niitsuma 2 0 13, figs 42 a, b). The adult somewhat resembles that of A. (A.) amamisimplex in the general appearance but can be easily separated by the number of spots along the anterior costal margin, which is three in A. (A.) jogancornua, and two in A. (A.) amamisimplex (Niitsuma 2013).	en	Niitsuma, Hiromi, Tang, Hongqu (2019): Taxonomic review of Ablabesmyia Johannsen (Diptera: Chironomidae: Tanypodinae) from Oriental China, with descriptions of six new species.

03B05940FFA8FFA5FF50F91CFAA0D2A4.taxon	discussion	Remarks. The male resembles that of A. (A.) monilis (Linnaeus) in the aedeagal complex with a dorsal lobe bearing an apical brush, a sinuate blade tapering toward a rounded apex and a well-developed lateral lobe, but differs from it in the wing with two dark spots along the costal margin and the aedeagal blade with no basal projection. In A. (A.) monilis, the wing possesses three spots at the apices of R 1, R 3 and R 4 + 5, and the aedeagal blade has a basal pointed projection (Fittkau 1962, fig. 397; Roback 1971, figs 573 – 575; Niitsuma 2013, fig. 3). In the redescription of A. (A.) monilis by Niitsuma (2013), the lateral lobe (LL) was mistaken for the lateral filaments (LF). What he has indicated as LF in his fig. 3 is the lateral lobe with filaments on the membranous base, and the lobe merges with the lateral filaments that are more lateral and continue further by merging with shorter filaments on the ventral side of the basidorsal lobe (B. Bilyj, pers. comm.). The structure is better defined in the lateral view. The males of A. (A.) alba and A. (A.) monilis may be separable from each other by the lateral lobe in the dorsal view, too, which was overlooked in the original description of the former species (N. Hazra, pers. comm.). The relative length to the aedeagal blade is 0.78 – 0.88 in A. (A.) alba, and more than 1.0 in A. (A.) monilis (see Niitsuma 2013, fig. 3). The distribution of A. (A.) alba extends from West Bengal State in India to Guangdong Province in China.	en	Niitsuma, Hiromi, Tang, Hongqu (2019): Taxonomic review of Ablabesmyia Johannsen (Diptera: Chironomidae: Tanypodinae) from Oriental China, with descriptions of six new species.

03B05940FFAAFFABFF50F9F5FB7AD0E4.taxon	discussion	Remarks. Although the tibia is three-banded in most species of the subgenus Ablabesmyia, four-banded tibiae occur in Australian A. (A.) notabils (Skuse), African A. (A.) rufa (Kieffer), A. (A.) appendiculata (Kieffer) and A. (A.) dusoleili Goetghebuer, and Indian A. (A.) ornatipes (Kieffer) as well as A. (A.) maculitibialis. Further, Brazilian A. ducke Neubern, A. fazzari Neubern, A. gessnerae Neubern and A. pinhoi Neubern also possess fourbanded tibiae, wings with separate dark spots and an apically expanded sub-terminal seta on the male gonostylus. As explained previously, however, these Brazilian species were not given any subgeneric status in the original descriptions (Oliveira et al. 2013). For comparison, major characters of these ten species are summarized in Table 3, according to Freeman (1961) and Roback (1982 a, b) for A. (A.) notabilis, Freeman (1955) for A. (A.) rufa, Freeman (1955) and Harrison (1978) for A. (A.) appendiculata and A. (A.) dusoleili, and Kieffer (1910) for A. (A.) ornatipes which is known about only the female, and Oliveira et al. (2013) for A. ducke, A. fazzari, A. gessnerae and A. pinhoi. The male of A. (A.) maculitibialis is characterized by the forefemur darkened on the basal two thirds and subapex, the four-banded tibia, the wing with three dark spots at apices of R 1, R 3 and R 4 + 5, and the aedeagal complex with a bare dorsal lobe, a slender blade tapering toward a pointed apex and a very long lateral lobe with apicolateral teeth. In the original description, Chaudhuri et al. (1983: 907) miscalculated the male antennal ratio, and it is 2.0, not 1.1, based on the relative lengths of flagellomeres. Notes: The aedeagal complex of A. (A.) rufa is not described. The male of A.

03B05940FFA7FFAEFF50FDD4FBA1D5C5.taxon	discussion	Remarks. The male is similar to that of A. (A.) janta (Roback) in possessing a slightly curved aedeagal blade with a pointed apex and the elongated lateral lobe with apical teeth, but distinct in the beak-shaped dorsal lobe and the much longer lateral lobe, which is twice as long as the aedeagal blade. In A. (A.) janta, the dorsal lobe is straight in dorsal view and the lateral lobe is at most 1.5 times as long as the blade (Roback 1971, 1985). The pupa is also separable from that of A. (A.) janta by the abdominal pigmentation pattern, which is entirely brown, occasionally darker anteromedially. In A. (A.) janta, the abdominal tergite IV has a pair of dark vertical bands (Roback 1985, fig. 228). In addition, the pupa of this new species is armed with sparse shagreenation consisting of solitary spinules on the abdominal tergites. The typical pupa of Ablabesmyia s. str., has tergal shagreenation composed of arched rows of 2 – 3 scales (Roback 1985, Fittkau & Murray 1986). In the pupal shagreen, A. (A.) pectinata sp. n. resembles A. (A.) rimae Harrison, too. Although the pupal description of the latter is incomplete, both the species are easily separated using the adult male hypopygium, specifically the aedeagal complex. The male of A. (A.) pectinata sp. n. possesses a beak-shaped dorsal lobe and a long lateral lobe with apical teeth, while that of A. (A.) rimae has a dorsal lobe with two apical projections and lacks a distinct lateral lobe (Harrison 1991).	en	Niitsuma, Hiromi, Tang, Hongqu (2019): Taxonomic review of Ablabesmyia Johannsen (Diptera: Chironomidae: Tanypodinae) from Oriental China, with descriptions of six new species.

03B05940FFA3FFB3FF50FD19FB4BD65D.taxon	discussion	Remarks. The male of A. (A.) praegracilis sp. n. is similar to that of above-described A. (A.) huananensis sp. n. in the wing with two dark spots at the ends of R 1 and R 4 + 5 and the costal vein ending above the tip of M 3 + 4, the mid- and hind legs each with a single tibial spur, the slender aedeagal blade with a pointed apex, and the membranous aedeagal lateral lobe, but can be separated by the thin dorsal lobe with apical spiculae. There are also similarities with the males of A. (A.) hilli Freeman and A. (A.) rimae Harrison as discussed under A. (A.) huananensis sp. n. In the former two species, however, the dorsal lobe is shorter than half of the aedeagal blade and lacks apical spiculae (see Roback 1982 b for A. (A.) hilli, Harrison 1991 for A. (A.) rimae).	en	Niitsuma, Hiromi, Tang, Hongqu (2019): Taxonomic review of Ablabesmyia Johannsen (Diptera: Chironomidae: Tanypodinae) from Oriental China, with descriptions of six new species.

03B05940FFBCFFB1FF50F972FC80D6C9.taxon	discussion	Remarks. The male has two dark spots along the costal margin of the wing. The aedeagal complex is characterized by the apparent absence of lateral lobe, the presence of a brush on the dorsal lobe, and the aedeagal blade armed with a projection near the middle, which is not a basal projection as in A. (A.) monilis (Linnaeus) (see Niitsuma 2013). The bifid aedeagal blade is unique for this genus. Within the genus Ablabesmyia, A. (A.) bifurca sp. n. and A. (Karelia) kisanganiensis Lehmann are exceptions in the adult with a palpomere 4 being longer than a palpomere 3. In most other species, the palpomere 4 is shorter than the palpomere 3 (Roback 1971, Murray & Fittkau 1989).	en	Niitsuma, Hiromi, Tang, Hongqu (2019): Taxonomic review of Ablabesmyia Johannsen (Diptera: Chironomidae: Tanypodinae) from Oriental China, with descriptions of six new species.

03B05940FFBEFFB7FF50FB17FC93D5EF.taxon	discussion	Remarks. Among the known species of the subgenus Karelia, the male is most similar to that of the Afrotropical species A. (Karelia) kisanganiensis Lehmann as the fourth palpomere is relatively long (Pm 4 / Pm 3 0.95 – 1.0), and the aedeagal complex has an elongated dorsal lobe and a blade tapering toward the pointed apex. In describing A. (Karelia) kisanganiensis, however, Lehmann (1981: 10) wrote, “ Dorsaler Lobus der Analhöhle gut entwickelt, sklerotisiert unt ohne Borsten; seine Spitze dorsalwärts gebogen. Blatt weitgehend gerade und apikal spitz zulaufend. Laterallobus deutlich, aber nicht sehr stark entwickelt. Lateralfilamente fehlen. ” These disagree with the features of the aedeagal complex in the new species: the strongly tapered dorsal lobe with apical spiculae, the distinctly curved aedeagal blade and the well-developed lateral lobe merged with lateral filaments. So far, only two species, A. (K.) paivai (Kieffer) and A. (K.) photophilus (Kieffer), have been known as the species of the subgenus Karelia from the Oriental region. The male of the former is smaller (total length 2 mm), and has entirely brown abdomen, according to Kieffer (1910). Unfortunately, the aedeagal complex is not described for this species. The latter is also distinct in the wing lacking the dark spot at the apex of R 4 + 5, the femora with three bands, and the aedeagal complex with a poorly developed dorsal lobe and an elongated lateral lobe (Chaudhuri et al. 1983). This is the first record of the subgenus Karelia from China.	en	Niitsuma, Hiromi, Tang, Hongqu (2019): Taxonomic review of Ablabesmyia Johannsen (Diptera: Chironomidae: Tanypodinae) from Oriental China, with descriptions of six new species.
