Merizomma codonopsivora Vilkamaa & Menzel 2019
No full textMerizomma codonopsivora (Sasakawa, 1997) stat. et comb. n. Literature. Lycoriella (Chorizomma) codonopsivora Sasakawa—Sasakawa (1997): 171, figs 1–3. Lycoriella (Merizomma) codonopsivora Sasakawa—Sasakawa (2003): 119, 128. Lycoriella codonopsivora Sasakawa—Sasakawa (2008): 128; Eiseman et al. (2016): 527. Discussion. Sasakawa (1997: 171) described the distinctive Lycoriella codonopsivora Sasakawa, 1997 from Hokkaido (Japan) whose larvae feed on deodeok leaves (Codonopsis lanceolata, Campanulaceae). For this species, he erected the monotypic subgenus Chorizomma of Lycoriella (Sasakawa 1997: 174 [preocc., not Chorizomma Simon, 1872; Araneae, Dictynidae] and renamed the subgenus later as Merizomma (Sasakawa 2003: 119, 128). The subgenus and the type species are not included in the monograph of the Palaearctic Sciaridae (Menzel & Mohrig 2000). Therefore, these taxa are discussed here in detail on the basis of the original descriptions by Sasakawa (1997) and included in the identification key and in the checklist. Lycoriella codonopsivora Sasakawa, 1997 has characters which are not present in this combination in any other genus and which distinctly differ from those given to Lycoriella s. l. by Menzel & Mohrig (2000: 377): Eye bridge not united at middle, without ommatidia; maxillary palpus 2-segmented, without pit of sensilla on 1 st segment; scutellum without long lateral setae, only with two unregular rows of short setae; R 1 longer than R, ending beyond the base of M-fork; fore tibia with small, bow-like bordered tibial organ; tarsal claws untoothed; hypopygium with wide gonocoxa; gonocoxae united in v-form and with short setae, intergonocoxal area not modified, gonostylus elongate-triangular and with apical megaseta, without apical tooth; medial side of gonostylus without megasetae and at apical half strongly impressed; basal part [at 1/5 of the medial side of gonostylus] with long, upcurved seta on long basal body; tegmen roundish, without apical or lateral modifications. On the basis of the above characters, L. codonopsivora Sasakawa must be excluded from the Lycoriella group. With its short gonocoxa, lacking intergonocoxal lobe and apical megaseta, the species resembles some species of the K. nepalensis group of Keilbachia Mohrig, 1987 [compare here Menzel & Martens (1995: 107), Menzel & Mohrig (2000: 348), Vilkamaa et al. (2006: 40) and Vilkamaa et al. (2009: 3)]. However, a strongly reduced eye bridge, a 2-segmented palpus, an unbordered patch of sensilla on 1 st segment of palpus, a long R 1 and the lack of a spiral-formed megaseta on the medial side of gonostylus differ from the characters of Keilbachia. These characters are typical for the M. hippai group of the genus Mohrigia Menzel, 1995. Speaking against the combination of L. codonopsivora Sasakawa with Mohrigia are the Keilbachia -like form of the gonostylus, the missing long medial setae on the apical half of the gonostylus, the missing intergonocoxal lobe of hypopygium and the much smaller, weakly setose fore tibial organ [compare here Menzel & Martens (1995: 102), Menzel & Mohrig (2000: 415) and Rudzinski (2006: 450)]. Furthermore, neither Keilbachia nor Mohrigia have the lateral setae of scutellum reduced [both have two long and strong setae] nor an unmodified tegmen [the tegmen of Mohrigia has a straight, strongly sclerotized dorsomedial structure; the tegmen of Keilbachia is sclerotized laterally and often with a narrow apical process]. On the above grounds, Merizomma Sasakawa, 2003 stat. n. with the type species Merizomma codonopsivora (Sasakawa, 1997) comb. n. is raised to generic rank and excluded from the Lycoriella group sensu Menzel & Mohrig (2000).Published as part of Vilkamaa, Pekka & Menzel, Frank, 2019, Re-classification of Lycoriella Frey sensu lato (Diptera, Sciaridae), with description of Trichocoelina gen. n. and twenty new species, pp. 1-67 in Zootaxa 4665 (1) on page 8, DOI: 10.11646/zootaxa.4665.1.1, http://zenodo.org/record/400055

Maxillary palpus long, with 3 segments, all segments narrow, 1 st segment with 4 sharp setae, with a dorsal unbordered patch of sensilla. Scapus and pedicellus dark bown and roundish; antennal flagellomers missing in the specimen studied. Thorax. Postpronotum non-setose. Scutellum with 8 long and strong setae. Legs. Strong, with long tibial spurs; tibial spurs of mid and hind tibiae unequally long [one spur is about 1/4 shorter than the other]; tarsal claws without teeth. Wing. Large, anal lobe strong, hind veins distinct, stCuA short, 1/3 of bM; bM = r-m, bM non-setose, r-m with 4–5 setae distally, c/w 0.50. Body length 2,7 mm, wing length 2,5 mm. BIN. Unknown. Discussion. The species was described from females from Northern Norway by Lengersdorf (1926): for the lectotype designation and literature, see Menzel & Mohrig (2000). After a study of the lectotype, which so far is the only specimen of the species (in ZFMK) available for study, Menzel & Mohrig (2000) stated that the scutellum has many long and strong setae, the 1 st palpal segment has a unbordered patch of sensilla, the fore tibia has spine-like setae, and that R 1 /R complex is long (R 1 ends near the level of the base of the M-fork). We have studied the lectotype again and have found characters that might be helpful in identification of the male of this species and for supporting its placement in the genus Trichocoelina. Of the characters given above, only the somewhat unequally long spurs of the mid and hind tibiae as well as the high number of long scutellars are unusual for Trichocoelina.Published as part of Vilkamaa, Pekka & Menzel, Frank, 2019, Re-classification of Lycoriella Frey sensu lato (Diptera, Sciaridae), with description of Trichocoelina gen. n. and twenty new species, pp. 1-67 in Zootaxa 4665 (1) on page 19, DOI: 10.11646/zootaxa.4665.1.1, http://zenodo.org/record/400055

Face and antenna concolorous brown, maxillary palpus pale brown. Eye bridge 3 facets wide. Face with 14 setae. Clypeus with 4 setae. Maxillary palpus with 3 segments, 1 st segment as long as 3 rd segment, 2 nd segment shortest; 1 st segment with 5 setae, with small dorsal pit with sensilla; surface of antennal flagellomeres smooth, body of 4 th antennal flagellomere 2.2x as long as wide, neck slightly shorter than wide, longest setae longer than width of flagellomere. Thorax. Brown; setae pale. Anterior pronotum with 5 setae. Proepisternum with 8 setae. Scutellum with 2 long and some short and fine setae. Wing. Fumose. Length 1.7 mm. Width/length 0.45. Anal lobe small. Veins distinct, except for stM. c/w 0.75. R1/R not detectable in the specimen studied. stM shorter than fork of M. bM and r-m subequal in length, stCuA shortest. bM and r-m non-setose. Halter yellow. Legs. Brown; setae pale. Fore tibial organ forming large patch of many setae in demarcated depression. Fore tibial spur slightly shorter than apical width of tibia. Abdomen. Pale brown; setae pale and moderately long. Hypopygium (Fig. 4B). Brown, like abdomen. Intergonocoxal area rather long, with short setose lobe. Gonocoxa longer than gonostylus, slightly roundish laterally, with rather dense and fine setosity. Gonostylus (Fig. 6C) widest subbasally, narrowed towards apex, strongly impressed medially, densely setose apically, with strong and curved apical tooth; with 5 medial megasetae in apical half, megasetae slender, long and straight, oblique, the apicalmost (with sockets) shorter than the others, as long as apical tooth; with well-differentiated long whip-lash seta in basal third of gonostylus. Tegmen (Fig. 13A) much wider than long, smoothly curved and membraneous apically, straight laterally, sclerotized basolaterally, with small area bearing a few aedeagal teeth. Aedeagal apodeme moderately long. BIN. Unknown. Discussion. Lycoriella eurystylata sp. n. resembles L. taimyrensis sp. n. and L. tundrae sp. n. in having the tegmen smoothly curved apicolaterally, whereas L. acutostylia Mohrig & Menzel, 1990 [described in Menzel et al. (1990)], L. jakovlevi sp. n. and L. kinbasketi sp. n. have the tegmen distinctly angled apicolaterally (Fig. 13). L. eurystylata differs from L. taimyrensis and L. tundrae in having the tegmen very short, strongly sclerotized basolaterally, semicircular apically and without tooth-like structures, whereas the other two have their tegmen only slightly sclerotized laterally, less curved apically and with tooth-like structures. Furthermore, L. eurystylata has five, L. tundrae four and L. taimyrensis eight to nine gonostylar megasetae and the fore tibial organ of L. eurystylata is more distinctly demarcated than that of L. taimyrensis and L. tundrae. L. eurystylata is similar to L. acutostylia, L. jakovlevi and L. kinbasketi in having rather long antennal flagellomeres (4 th flagellomere 2.1–2.3 times as long as wide), whereas L. taimyrensis and L. tundrae have shorter flagellomeres (4 th flagellomere 1.4–1.6 times as long as wide). To distinguish L. taimyrensis and L. tundrae, see under the former, and to distinguish L. acutostylia, L. jakovlevi and L. kinbasketi, see under L. jakovlevi sp. n. Etymology. The name is derived from the Greek words eurys, broad, and stylos, style, referring to the thick gonostylus of the male hypopygium.Published as part of Menzel, Frank & Vilkamaa, Pekka, 2021, New species and records of Lycoriella Frey (Diptera, Sciaridae) from the Holarctic region, pp. 501-530 in Zootaxa 5072 (6) on pages 507-509, DOI: 10.11646/zootaxa.5072.6.1, http://zenodo.org/record/575154

The species was described from Greenland (Rübsaamen, 1898), and redescribed and illustrated by Menzel & Mohrig (2000), with the discussion of the type material. Trichocoelina cochleata is characterized by having a medially impressed gonostylus, with a strongly curved apical part. The antennal scapus and pedicellus as well as the hypopygium and legs are yellow, but the apex of gonostylus has strikingly dark setosity. The gonostylus bears 6–7 rather long and slender gonostylar megasetae, the tegmen is broadly subconical with a sclerotized dorsoapical process. The intergonocoxal lobes of the hypopygium are short.

The species is characterized by its broadly clavate gonostylus, with an apical tooth on the dorsal side, and two to three flagellate setae on the apical half; gonocoxite with a wide intercoxal lobe bearing long and dense setae on the ventral side; tegmen longer than wide and apically rounded, parameral apodeme continuously sclerotized forming a central strip on dorsal side; ventral inner side of gonocoxite with long setae; R1 significantly longer than R and extended to the base of the M-fork; eye bridge narrow with perpendicular frontal process and the ommatidia lost at the center (Menzel & Mohrig, 2000). Distribution. China (Tibet— new record; Fig. 16); Nepal (Simbhanjang), Burma (Kambaiti) (Menzel & Martens, 1995; Menzel & Mohrig, 2000). Remarks. This species was first recorded from Nepal and is new to China. The Chinese specimen shares the diagnostic characteristics, but slight differences were found (a broader gonocoxite and a narrower tegmen).Published as part of Xu, Jun, Shi, Kai, Huang, Junhao & Wu, Hong, 2017, Review of the genus Mohrigia Menzel (Diptera, Sciaridae) from China, pp. 71-98 in Zootaxa 4300 (1) on pages 77-78, DOI: 10.11646/zootaxa.4300.1.4, http://zenodo.org/record/83715

Width/length 0.35–0.40. Anal lobe weak. Veins distinct. c/w 0.50–0.60. R 1 /R 0.50–0.90. stM shorter than fork of M. r-m longer than bM, bM non-setose, r-m non-setose or with 1–2 setae. Halter yellow. Legs. Yellow, coxal setae pale. Fore tibial organ forming a large patch in shallow depression. Fore tibial spur as long as the tibial width. Abdomen. Pale brown, setae pale, short and fine. Hypopygium (Fig. 10 B). Brown, as abdomen. Intergonocoxal area long, with two short setose lobes. Gonocoxa broad, as long as gonostylus, medial margin basally smoothly curved, with short and fine setosity. Gonostylus (Fig. 10 A) voluminous, apically truncate, impressed; with short setosity, a short apical tooth, and numerous megasetae in the medial impression; megasetae slightly curved or straight, short and slender; with 1 well-differentiated whiplash seta basally at ventromedial margin. Tegmen (Fig. 17 D) longer than broad, laterally straight, apically with a narrow hyalinous acuminate process, weakly sclerotized, aedeagal teeth not detectable in the specimens studied. Aedeagal apodeme long. BIN. BOLD:ACK5495. Discussion. In Fig. 10 A the gonostylus is flattened and distorted to show the arrangement of the megasetae. In its extremely voluminous gonostylus, Trichocoelina janetscheki (Lengersdorf, 1953) resembles most T. incrassata sp. n., for distinguishing characters, see under the latter.Published as part of Vilkamaa, Pekka & Menzel, Frank, 2019, Re-classification of Lycoriella Frey sensu lato (Diptera, Sciaridae), with description of Trichocoelina gen. n. and twenty new species, pp. 1-67 in Zootaxa 4665 (1) on page 33, DOI: 10.11646/zootaxa.4665.1.1, http://zenodo.org/record/400055
