The species is previously known from Venezuela and from Santa Catarina, Espírito Santo and Sergipe States in Brazil (Pinho et al. 2009). New records from Santa Catarina and Amazonas States are provided. Remarks. Pinho et al. (2009) stated that “One male from Urubici, Santa Catarina State, is slightly larger than the other specimens with a wing length of 1.3 mm compared to 0.8–1.1 mm ” and “more material is necessary to decide if this specimen falls within the variation of D. plaumanni or if it represents a separate species”. Four additional males from Urubici have been collected later and their wing length range from 1.2 to 1.3 mm, so the specimens are considered to belong to D. plaumanni. The wing length of the specimen from Amazonas is 0.7 mm. Thus, the wing length of the species should be emended as 0.7–1.3 mm.Published as part of Shimabukuro, Erika Mayumi, Lamas, Carlos José Einicker & Pinho, Luiz Carlos, 2020, Brazilian Diplosmittia Saether: D. trifida sp. n. and new records of D. plaumanni Pinho, Mendes & Andersen, 2009 (Diptera: Chironomidae), pp. 139-142 in Zootaxa 4885 (1) on pages 141-142, DOI: 10.11646/zootaxa.4885.1.10, http://zenodo.org/record/429629

Paratype: 1 adult female, slide mounted, as allotype (UFSC). Etymology. The specific epithet honors the Xokleng people, the original inhabitants of the type location, who have been brutally decimated since the beginning of colonization by those of European extraction in southern Santa Catarina state. The name is to be regarded as a noun in apposition. Diagnostic characters. This species differs from other extant Corethrella by the following combination of characters: Adult male: trochanter and base of hind femur paler than apex of femur, 3rd palpal segment clavate (apically expanded), 4 thick setae on frons, empodia thick, with 10 bifid branches. Adult female: Wings and legs uniformly pigmented, head rounded in dorsal view, 3rd palpal segment clavate (apically expanded), four thick setae on frons, empodia thick, with 10 bifid branches. Description. Adult male (n=1). (Tables 1, 2, Figs. 3, 4 A–D) Head (Fig. 3A). Rounded in anterior view. Coronal suture long, reaching ventral margin of eye bridge. Four parallel thick setae on frons. Palpus (Fig. 4A) medium brown, with 3rd segment somewhat expanded apically, 5 th segment with about double the length of 4th. Clypeus (Fig. 4B) square with three setae on dorsal surface. Antenna (as in Fig. 4H) brown with flagellomere 13 apically bifurcated. Sensilla coeloconica distributed according to table 1. Thorax (Fig. 3B). Light to medium brown, with mesonotum darker, anepimeron with one seta, pale with central portion more darkly pigmented. Posterior anepisternum with incomplete diagonal suture at ventral margin. Anterior anepisternum divided in half by transversal suture. Prescutal suture long, almost reaching dorsocentral row of setae. Group of five setae on posterior portion of dorsocentral row. Katepisternum pale around ventral margin. Wings (as in Fig. 3B). Plain brown, with setae instead of scales on non-marginal veins. Vein R 1 somewhat bolder. Apex of R 2 basal to the one of M 1. Halter slightly lighter or same color than scutellum. Legs (Fig. 3B). Uniformly medium brown, except midleg trochanter, lighter than femur and trochanter, base of hind femur lighter than apex of femur. Legs without scales. Tarsal claws equal, inserted apically. Empodia (as in Fig. 4C) thicker than apical setae of last tarsomeres, longer than average diameter of last tarsomeres, with 9–10 bifid branches. Abdomen. Uniformly medium to dark brown. Genitalia (Figs. 3C, 4C, D). Gonocoxite (Fig. 3C) medium to dark brown, elongate, slender; dorsal row with five setae, the first slightly thinner than the rest. 5th seta medially dislocated; one dorsomedial thicker seta, tapering from midlength. Gonostylus with constant width subtly bent subapically, with apical seta very short and thick. subbasal seta located posteroventrally at 0.2 of gonostylus, length about 0.3 of gonostylus. Aedeagus (Fig. 4C) long, strongly tapering from base; margins fused near apex. Adult female: (n=2) (Tables 1, 2, Figs. 4 E–H, 5) as for male, except: Head (Fig. 5A). Coronal suture short, ending close to dorsal margin of eye bridge. Palpus (Fig. 4F) with 3rd segment clavate. Clypeus (Fig. 4G) with 6–8 setae on dorsal surface. Sensilla coeloconica distributed according to table 1. Abdomen (Fig. 5D). Medium to dark brown. Cercus equally pigmented. Immatures. Unknown. Distribution and biology. This species is known from three individuals (two females and one male) collected in light traps from type locality, Serra Furada State Park, in Grão Pará, SC, at elevations of 355– 354 m. Serra Furada is a region of Atlantic Forest, interspersed with large areas of Eucalyptus cultivation, near the transition to Araucaria Forest at higher altitudes. The rivers where traps were set are gravel-bed streams, 4–6m wide and about 1m deep. Taxonomic discussion. This species shares the synapomorphies which define the rotunda group (as designated by Borkent, 2008): wings without a pattern of pigmentation and posterior anepisternum with contiguous ventral and dorsal portions. Male flagellomere 8 shorter than both 7 and 9, wing with apex of R 2 basal to apex of M 1 and the presence of setae instead of scales on wing veins place Corethrella xokleng sp. n. among the clade formed by C. kerrvilensis (Stone), C. remiantenalis Borkent, C. blandafemur Borkent, C. brevivena Borkent, and C. globosa Borkent. Corethrella xokleng sp. n. does not share the synapomorphies that group C. remiantenalis with C. blandafemur or C. brevivena with C. globosa, respectively, suggesting it may be the sister to a clade comprised of all four of these species. Females and males of C. xokleng sp. n. were associated by their shared pigmentation patterns on wings and legs, the collecting location, the pattern of empodia and by the 4 setae on the frons, the latter being a unique character among rotunda group.Published as part of Amaral, André P., Mariano, Rodolfo & Pinho, Luiz Carlos, 2019, Four new species and some new records of Brazilian frog-biting midges (Diptera Corethrellidae), pp. 103-120 in Zootaxa 4706 (1) on pages 110-112, DOI: 10.11646/zootaxa.4706.1.4, http://zenodo.org/record/356511

Hind femur 309 μm long; hind tibia 358 μm long; tarsomere lengths (in μm): 152, 88, 88, 29, 34. Spurs of hind tibia 27 and 12 μm long. Width at apex of hind tibia 10 μm.</p> <p> <i>Hypopygium</i> (Figure 1 B–E). Anal point not crested (Figure 1B), 10 μm long, 25 μm wide at base, 7 μm wide at apex, with 6 strong setae. Laterosternite IX with 3 setae. Phallapodeme 80 μm long. Transverse sternapodeme 40 μm long. Virga 62 μm long (Figure 1C). Gonocoxite 75 μm long, without volsellae (Figure 1 B–C). Gonostylus with three lobes (Figure 2 D–E); main lobe 39 μm long, ventromedially projecting lobe 57 μm long, dorsocaudally projecting lobe 30 μm long; megaseta 12 μm long. HR 1.92; HV 3.84.</p> <p> <b>Female and immatures.</b> Unknown.</p> <p> <b>Distribution (Figure 1).</b> <i>Diplosmittia trifida</i> <b>sp. n.</b> is only known from the type locality, Neblina Peak, Northwestern Brazil, where it was collected in a Malaise trap placed close to a low order stream at 1600 m a.s.l. Only a single male was collected despite intensive sampling effort during the expedition with successive sampling with light traps, emergence traps and Malaise traps from 100 m up to 2800 m a.s.l.</p> <p> <b>Remarks</b>. The new species belongs to <i>Diplosmittia</i> due to the combination of the following diagnostic characters established by Pinho <i>et al</i>. (2009): two short acrostichals in midscutum, absence of volsellae, and presence of a deeply divided gonostylus. Also, the strongly sinuous Cu 1 of <i>D. trifida</i> <b>sp. n.</b> is present in most <i>Diplosmittia</i> species. The third lobe of the gonostylus, i.e., the dorsocaudally directed lobe seems to be derived from the base of the dorsal surface of the main lobe of gonostylus. The new species shares some similarities with <i>D. plaumanni</i>, such as the well-developed costal extension, patches of microtrichia in some parts of body, an anal point without crest, projected beyond the posterior margin of tergite IX and the presence of a long virga with bulbous base.</p>Published as part of <i>Shimabukuro, Erika Mayumi, Lamas, Carlos José Einicker & Pinho, Luiz Carlos, 2020, Brazilian Diplosmittia Saether: D. trifida sp. n. and new records of D. plaumanni Pinho, Mendes & Andersen, 2009 (Diptera: Chironomidae), pp. 139-142 in Zootaxa 4885 (1)</i> on pages 139-141, DOI: 10.11646/zootaxa.4885.1.10, <a href="http://zenodo.org/record/4296299">http://zenodo.org/record/4296299</a>
