In China this species is reported from Yunnan, Guangxi and Guangdong under the species name C. liebenauae (Shi &amp; Tong 2019).</p> <p>Comment. The description given above contains some corrections and clarifications to the original description. In the original description (Kluge et al. 2020) we wrongly reported that «Inner-dorsal side of fore femur with few stout setae, length of these setae being half that of setae on dorsal side». Actually, in C. (Crassolus) ingridae the stout setae on outer side of femora are long and more numerous than in other species, while the stout setae on inneranterior side of fore femur are very small, many times shorter than the setae on outer side (Fig. 402).</p> </div>	http://treatment.plazi.org/id/03936656F63EE00E7AB0FAF8FB05FE8D	Public Domain	No known copyright restrictions apply.

Centroptella (Crassolus?) bifida (Shi &amp; Tong 2019)</p> <p>(Fig. 421)</p> <p>Bungona (Chopralla) bifida Shi &amp; Tong 2019: 578 (larva);</p> <p>Centroptella bifida: Kluge, Godunko &amp; Svitok 2020: 92.</p> <p>Distribution. China.</p> <p>Comments. Centroptella bifida is known as larvae only. According to the original description, its larvae differ from others as «submarginal setae on labrum are forked apically» (Shi &amp; Tong 2019: 578, 584, fig. 37). Actually, these setae are bifurcate in some other species as well, particularly in C. ingridae (Fig. 395), which in the same paper by Shi &amp; Tong (2019) was redescribed under the name « Bungona (Chopralla) liebenauae » and told to have «labrum surface with simple submarginal setae» (Shi &amp; Tong 2019: 584).</p> <p>Form of right prostheca (pressed to kinetodontium and lacking long process) suggests that C. bifida belongs either to Chopralla, or to Crassolus. Male larvae used for the original description, are not mature enough to have subimaginal gonostyli, so their pose is unknown (Xiaoli Tong, personal communication). Judging by the presence of denticles on posterior margins of abdominal terga II–X and the presence of setal rows (j) on abdominal sterna III–VI (Shi &amp; Tong 2019: 578), C. bifida probably belongs to Crassolus.</p> <p>Judging by the picture provided by Xiaoli Tong (Fig. 421), hypodermal coloration of mature male larva is limited by reddish stripes on posterior margins of abdominal terga, that clearly separates this species from such representatives of Crassolus, as C. ludmilae, C. pontica, C. inzingae and C. saxophila, whose males have more extensive hypodermal coloration on abdominal terga.</p> </div>	http://treatment.plazi.org/id/03936656F636E00F7AB0FDA2FD87F83E	Public Domain	No known copyright restrictions apply.

Fore wing length of male and female 3.2–5 mm.</p> <p>Synonymy of C. ceylonensis and C. similis. Müller-Liebenau (1983) described Centroptella ceylonensis and C. similis bases on larvae only and stated that «The main difference between both species is the lack of hind wing pads in C. similis sp. n. (in both sexes)». In reality, presence and size of larval vestiges of hind protoptera varies individually in this species (while hind wings are always completely absent in winged stages); among examined larvae of C. ceylonensis from one and the same population (Delhausie near Sri Pada), some individuals have wellexpressed vestiges of hind protoptera, some have very small convexities instead of them, some have not vestiges of hind protoptera at all, and some have vestige of hind protopteron on one side and no such vestige on another side (as in Figs 510–511).</p> <p>Besides this character, Müller-Liebenau (1983) noted: «Also the size ratio of turbinate eyes and the lateral eyes appears somewhat different in the male nymphs of both species». Actually, the drawings of male larval heads (Müller-Liebenau 1983: figs 1p and 2a) do not allow to distinguish these species.</p> <p>Müller-Liebenau (1983) also noted that scales on abdominal terga are «in general a little more elongate in C. ceylonensis sp. n. ». Actually, the scales significantly vary in size and proportions on terga of one and the same individual, that is visible from the photos in the original description (Müller-Liebenau 1983: figs 5, 7).</p> <p>According to the original description of C. similis, its cuticular coloration of larval abdomen somewhat differs from that of C. ceylonensis. Actually, the coloration of abdominal cuticle varies individually in greater degree than it is shown on the pictures in the original descriptions of C. ceylonensis and C. similis. Thus, the name C. similis should be regarded as a junior synonym of C. ceylonensis.</p> <p>Distribution. Southern India (Western Ghats) and Sri Lanka.</p> <p>Variability. Hypodermal coloration of abdomen significantly varies individually within each population (Figs 456–463, 470–472). The examined specimens from Sri Lanka are larger (fore wing length 4.5–5 mm) then the examined specimens from India, whose fore wing length is 3.5–4 mm. However, examination of many imagines of both sexes individually associated with their larval and subimaginal exuviae allowed to conclude that populations from Sri Lanka and India belong to one and the same species.</p> <p>Species determination. In Sri Lanka Centroptella (Chopralla) ceylonensis is the single species of Chopralla and cannot be confused with other species. In southern India C. (Ch.) ceylonensis can be confused with the closely related species C. (Ch.) ghatensis sp. n., whose larvae differ only by presence of denticles on abdominal terga V–VIII and winged stages are indistinguishable from C. (Ch.) ceylonensis.</p> <p>Selvakumar et al. (2017) determined larvae of Chopralla from southern India as C. pusilla. Resolution of the total photo (Selvakumar et al. 2017: fig. 6) allows to see a pair of large denticles on lateral angles of the posterior projection of tenth abdominal tergum, that differs C. ceylonensis (Fig. 433) from C. pusilla (Fig. 630); other characters of the larvae reported by Selvakumar et al. (2017) (i.e. coloration, mandibular structure, arrangement of denticles on abdominal terga) also agree with the characteristics of C. ceylonensis. The photo indicated as «Foreleg» (Selvakumar et al. 2017: fig. 10) actually belongs to the hind leg.</p> </div>	http://treatment.plazi.org/id/03936656F634E03A7AB0F8F4FC88F935	Public Domain	No known copyright restrictions apply.

Outer-apical seta of tibia blunt and elongate (as in Fig. 364).</p> <p>LONG, FINE SETAE: Bifurcate setae of metasternum (i) (see Centroptella s. l.) form pair of dense, regular rows partly with contiguous sockets (as in Fig. 517). Posterior arm of U-shaped row of long setae on fore- and middle leg situated across tibia, on hind leg longitudinal [see Chopralla (1)] (Müller-Liebenau 1984a: fig. 5h). Dorsal side of each tarsus with long, fine setae situated irregularly and partly forming two longitudinal rows (as in Figs 562–563; see Centroptella s. l.). Tergum VII with pair of fine, V-shaped setae sublaterally (g) (as in Fig. 604). Each sternum IV–V with pair of regular, transverse rows of long, fine, bifurcate setae with spaced sockets (j); other sterna either without such setae, or with few setae irregularly situated [see Chopralla (4)].</p> <p>MALE GENITALIA IN LARVA: In last larval instar, developing subimaginal gonostyli folded under larval cuticle in « Nigrobaetis - type » pose, with 2nd and 3rd segments directed caudally and inserted into previous ones (Fig. 627) [see Chopralla (5)].</p> <p>Subimago.

In the original description, labrum is figured as relatively long, with unusual shape of lateral sides (Müller-Liebenau 1984a: fig. 5a). Type specimens were kept in Purdue University (USA), but now are probably missing (L. Jacobus, personal communication). My determination of the specimens examined as C. pusilla is based on the assumption that Müller-Liebenau took the internal arms of labrum for lateral-proximal margins of the labrum (Figs 628–629).</p> <p>Distribution. Borneo. Selvakumar et al. (2017) erroneously reported C. pusilla from southern India; actually the larvae from India reported by them belong to C. ceylonensis (see above).</p> </div>	http://treatment.plazi.org/id/03936656F6EAE0D17AB0FD26FC0AFB6F	Public Domain	No known copyright restrictions apply.

Holotype of C. colorata: immature male larva of last instar (see Kluge et al. 2020). Holotype and paratypes of C. fusina: photos provided by Xiaoli Tong.</p> <p>Distribution. Vietnam and Hong Kong.</p> <p>Comments: type specimens of C. colorata. Originally, C. colorata was described as larvae and female subimago extracted from mature larva (Soldán et al. 1987). At present, only the holotype, male larva of last instar, is retained, wile the paratypes are lost.</p> <p>According to the original description, «posterior margin of terga... IV–X with stout pointed triangular teeth arranged into a simple row» (Soldán et al. 1987: 346); however, in the holotype tergum IV has no denticles (teeth), and the denticles are present beginning from the tergum V (Fig. 682). Structure of tergum X was not reported in the original description; the holotype has one pair of large denticles on angles of its posterior projection (Fig. 683).</p> <p>The combination of larval characters of C. colorata (right prostheca V-shaped, denticles on posterior margins of abdominal terga V–IX, tenth abdominal tergum with one pair of large denticles only) agrees with that of the new Indian species C. ghatensis sp. n. Both larvae and winged stages of C. colorata well differ from C. ghatensis sp. n. by absence of hypodermal coloration on abdominal terga. The holotype of C. colorata examined by me has very contrasting brown markings on cuticle of thoracic terga and pleura and on abdominal terga (Fig. 681), but its hypoderm under cuticle is entirely colorless. According to the original description, the female subimago extracted from larva had «Body pale whitish.... Abdominal terga without markings» (Soldán et al. 1987: 346). This means that the absence of hypodermal coloration observed in the larva kept in alcohol during 36 years was not caused by some selective depigmentation of the hypoderm (with cuticular pigmentation well preserved), but was initially inherent to these specimens. In contrast to C. colorata, male and female larvae and winged stages of C. ghatensis sp. n. have very intensive and contrasting hypodermal coloration of abdominal terga, which have not become paler after seven years preservation in alcohol.</p> <p>Comments: type specimens of C. fusina. C. fusina was described from Hong Kong based on 4 larvae, one male and one female imagines and one male subimago, with female larva designated as the holotype. Both imagines and the subimago reported in the original description, were individually reared from larvae, and their subimaginal exuviae were preserved and examined, but this fact was not reported in the original description (personal communication by Xiaoli Tong). On the drawing of male imaginal genitalia given in the original description (Tong &amp; Dudgeon 2003: fig. 16), terminal segments of gonostyli are somewhat longer than on the photo of the slide from which this drawing was done (Fig. 684).</p> <p>Larva of C. fusina was said to differ from C. colorata in the color pattern of pronotum and mesonotum and in three morphological characters as follows (Shi &amp; Tong 2019):</p> <p>(1) «The prostheca of right mandible bifurcated and plumose... (vs. the right prostheca plumose but not bifurcated in B. colorata)». In the original description of C. colorata the prostheca is really characterized as «plumose but not branched», but figured as bifurcate with branches brought together (Soldán et al. 1987: fig. 17).</p> <p>(2) «Tergites V–X with acute triangular spines on posterior margins... (vs. tergites IV–X with such spines in B. colorata)». This statement was based on the original description of C. colorata, which disagrees with the holotype structure (see above). Actually both the holotype of C. colorata and the type specimens of C. fusina have rows of denticles (i.e. spines, or teeth) on posterior margins of abdominal terga V–IX and one pair of large denticles on posterior projection of tergum X (Figs 682–683, 685–686).</p> <p>(3) «Gill I less than 4 times as long as wide, and other gills relatively broad, much less than 2.5 times as long as wide)... (vs. in B. colorata, gill I more than 5 times as long as wide and other gills narrow-elongate and at least 2.5 times as long as wide)». Actually, tergalii (so called «gills») of C. colorata never had been figured, and this comparison was based on the wordily description only, which stated that «gill 1... more than 5 times longer than broad; gills 2–5 apically rounded or bluntly pointed... about 2.5–3.5 times as long as broad» (Soldán et al. 1987: 346). Actually, tergalii of the holotype of C. colorata are wider than reported in the original description (Figs 673–679).</p> <p>Color pattern of pronotum and mesonotum somewhat differs in the original description of C. colorata (Soldán et al. 1987: fig. 26), on the holotype (Fig. 681) and in the redescription of C. fusina (Shi &amp; Tong 2019: figs 52, 59), that can be explained as individual variability.</p> <p>Based on this, I propose the following subjective synonymy: C. colorata = C. fusina syn. n.</p></div> 	http://treatment.plazi.org/id/03936656F6E2E0DE7AB0F8CFFB37FA98	Public Domain	No known copyright restrictions apply.
