We name the new species using this word in the Miao language not only because the new species resembles a miniature dragon, but also because the dragon is an important mythological figure in local Miao culture: Yangl Vongx, meaning “Calling for Dragon”, is a major festival for Miao People celebrated every 12 years, where they sacrifice livestock and set fireworks to worship dragons, in the hope that dragons will visit them in the coming years and bring proper rains for the crops. We suggest “ +ḄỆ棱# +” (Pinyin: Zhao Long Leng Xi) as its Chinese common name, and Dragon Water Skink as its English Common name. + + + + +Distribution and natural history. +The new species inhabits tropical karst forest. The +holotype +was found in a narrow rock crevice at night where the individual anchored itself deep inside ( +Fig.4 +), and the rock was in close proximity to small streams. The +paratype +was found on the forest floor at night. + +Acanthosaura lepidogaster + +, + +Cyrtodactylus gulingqingensis + +, + +Calotes emma + +, + +Cuora mouhtii + +were found sympatric with the new species at the type locality. Currently it is known from the type locality and the adjacent Hekou County in Honghe Prefecture, southeastern +Yunnan Province +, +China +(personal communication with Mr. Miao Benfu), and it is very likely to inhabit the border region in +Lao Cai Province +of northwestern +Vietnam +as well. + + + + \ No newline at end of file diff --git a/data/9F/02/AC/9F02AC77FFBC581114E9FE01D074F945.xml b/data/9F/02/AC/9F02AC77FFBC581114E9FE01D074F945.xml new file mode 100644 index 00000000000..39ba2a34dd3 --- /dev/null +++ b/data/9F/02/AC/9F02AC77FFBC581114E9FE01D074F945.xml @@ -0,0 +1,723 @@ + + + +A new species of the genus Rambutanura Deharveng, 1988 from southern Vietnam (Collembola, Neanuridae) + + + +Author + +Babenko, Anatoly +0000-0002-6077-0619 +The Severtsov Institute of Ecology and Evolution, Russian Academy of Sciences, Moscow 119071, Russia +lsdc@mail.ru + + + +Author + +Antipova, Maria +0000-0002-3517-9720 +The Severtsov Institute of Ecology and Evolution, Russian Academy of Sciences, Moscow 119071, Russia +antimar.2410@gmail.com + +text + + +Zootaxa + + +2024 + +2024-07-24 + + +5486 + + +1 + + +142 +150 + + + + +http://dx.doi.org/10.11646/zootaxa.5486.1.7 + +journal article +10.11646/zootaxa.5486.1.7 +1175-5326 +13209835 +25439543-6213-4A86-968C-676868FA0470 + + + + + + + +Rambutanura oblita + +sp. nov. + + + + + + +Figs 1–16 +, +Table 1–3 + + + + +Type material +. + +Holotype +: female, +Vietnam +, +Dong-Nai Province +, Ma-Da +Forest +, + +13 June 1995 + +, +Tatiana K.

A species of the genus characterized by the presence of elongated finger-shaped tubercles only on the last three abdominal segments, a large and variable number of dorsal sensilla in Ant.

+ + + +Etymology +. The name of the new species (feminine in gender, from the Latin +oblitus(a) +meaning forgotten) reflects the quite long temporal gap between its capture in nature and the description. + + + +FIGURES 2–5 +. + +Rambutanura oblita + + +sp. nov +. + +: 2, dorsal chaetotaxy; 3, anterior part of a head with tubercle Af; 4, ventral chaetotaxy of a head; 5, chaetotaxy of abdominal sterna. Scales: 2, 5, 1 mm, 3–4, 0.1 mm. + + + + +FIGURES 6–16 +. + +Rambutanura oblita + + +sp. nov +. + +: 6, maxillary apex; 7, mandible; 8, Ant. I–IV (lateral view); 9, tip of Ant. IV; 10, Ant. III, ventral side; 11–13, different types of setae (mesoseta, macroseta and sensillum) on tubercle Dl (Th. II); 14, cuticular reticulation on finger-like tubercle (Di+De+Dl) of Abd. V; 15, unguis; 16, male genital plate. Scales: 8–15, 0.1 mm, 6–7, 16, 0.01 mm. + + + +Affinities +. The status of + +R. oblita + + +sp. nov +. + +as a distinct species can hardly be questioned. The most striking distinctive feature of the new species is undoubtedly the presence of six finger-shaped tubercles on the last three abdominal segments, this clearly bringing it closer to four of the five known species of the genus. The degree of development of these outgrowths in the new species is lower, as in all congeners these are developed not only on the abdomen, but also on the head and thorax. Thus, in + +R. yoshiiana +Deharveng, 1988 + +, the +type +species of the genus, all tubercles on the body, including the head, are elongated and finger-shaped, whereas only tubercles Di on the abdomen of + +R. malayana +( +Yosii, 1976 +) + +are not elongated. + +Rambutanura dawydoffi + +is characterized by digitate tubercles on the head, the last abdominal segments and laterally on Th. II–Abd. III, whereas tubercles in the mid parts of the terga are low. In + +R. carcharia + +, only tubercles Di on Th. I–Abd. IV are not elongated. However, the identical tuberculization, the plurichaetosis on the antennae and dorsal tubercles, a slightly increased number of dorsal sensilla, as well as such an unusual character as the absence of dorsal sensilla from AOIII (which is also characteristic at least of + +R. yoshiiana + +, + +R. malayana + +and + +R. carcharia + +) obviously indicate a fairly close relationship of + +R. oblita + + +sp. nov +. + +with the other congeners that show a more pronounced elongation of dorsal tubercles across the body. + + +The presence of only a small number of finger-like tubercles in the new species makes it comparable to the only Chinese representative of the genus, + +R. hunanensis +Jiang & +Dong, 2018 + +( +in + +Dong +et al +. 2018 + +), which is characterized by prominent, but not finger-shaped tubercles. That species can easily be distinguished from + +R. oblita + + +sp. nov +. + +, for example, by the presence of a large number of dorsal sensilla (444/44444, including those on Th. I and on tubercles Di on all terga in + +R. hunanensis + +, +vs +22/ +22211 in + +R. oblita + + +sp. nov +. + +). + + +It seems noteworthy that the attribution of + +R. hunanensis + +to the genus + +Rambutanura + +has required a significant expansion of the latter’s original diagnosis, in particular the inclusion of species with tubercles both +swelling or finger-like in shape +( + +Dong +et al +. 2018 + +, p. 384). This expansion has led to the problem of separating the genus + +Rambutanura + +from + +W. vicina +( +Denis, 1934 +) + +, the +type +species of the genus + +Womersleya +Denis, 1948 + +, +which shows the same arrangement of tubercles as +Rambutanura +, +but… differs from that genus by the absence of any digitation on the head and tergites and a much lower plurichaetosis +( +Deharveng 1988 +, p. 714–715). When erecting the genus + +Rambutanura +, +Deharveng(1988 +,p.715) + +considered +the differentiation of digitations as a major apomorphic character +, and placed this genus + +in the “digitanurian” line ( +Deharveng 1987 +) together with + + +Digitanura + +Deharveng, 1987 + + +, a second South Asian genus with finger-shaped tubercles at the end of the abdomen, differing from + +Rambutanura + +in the arrangement of the dorsal tubercles on the head and Abd. V (tubercles Di separate). The situation is complicated since, according to the recent cladistic analysis ( +Smolis & Paśnik 2020 +), the genus + +Womersleya + +, along with other genera of the ‘bilobellan lineage’ of the tribe +Paleonurini +, was transferred to the tribe +Neanurini +, while the genus + +Rambutanura + +remained in the +Paleonurini +, as well as + +Pronura +Delamare Deboutteville, 1953 + +of the same ‘bilobellan lineage’ (see + +Bellinger +et al +. 1996 + +–2024). This ‘bilobellan lineage’ also contains species, such as + +Bilobella digitata +Cassagnau, 1967 + +, which tend to form finger-shaped tubercles at the end of the abdomen, although overall they are not very similar to the described species. All this quite clearly indicates that the existing generic and tribal division of the subfamily +Neanurinae +is rather far from ideal and in need of further attention. + + +The second, no less intriguing trait of the new species, is undoubtedly the chaetotaxy of the fourth antennal segment. The vast majority of the known species in the subfamily are characterized by the existence of a constant and characteristic arrangement of setae on the dorsal side of Ant. IV ( +Deharveng 1981 +) and +this feature is the most important and least controversial criterion for belonging to + +Neanurinae +( +Smolis & Paśnik 2020 +, p. 498) + +. Plurichaetosis of ordinary mou setae on Ant. IV was already indicated in the original diagnosis of the genus ( +Deharveng 1988 +) and it seems to be typical of all known species of the genus, including + +R. oblita + + +sp. nov. + +But the increased and rather unstable number of blunt dorsal sensilla on Ant. IV has previously not been noted among the species of the subfamily, this obviously being a unique character of the new species. + + + + \ No newline at end of file
