[Botany • 2021] Lippia raoniana (Verbenaceae) • Checklist and A New Species of Lippia from the Diamantina Plateau, Minas Gerais, Brazil


Lippia raoniana P.H.Cardoso & Salimena

in Cardoso, Neto, Trovó et Salimena, 2021. 

Abstract
The Diamantina Plateau is located in the central region of the Espinhaço Range, in the State of Minas Gerais, which is dominated by campo rupestre formations. We describe a new species of Lippia L., endemic to the Diamantina Plateau, and provide an annotated checklist and identification key for the 17 species of the genus occurring in the area. Lippia raoniana P.H.Cardoso & Salimena sp. nov. is mainly distinguished by its ovate leaves with adaxial and abaxial surfaces densely covered by sessile glandular trichomes, and drupaceous fruits with two pyrenes. It is known only from two populations, and thus can be provisionally considered as Critically Endangered. Details on the species’ ecology, as well as a comparison with morphologically similar species, a distribution map, and field photographs, are provided. In this work, we also present pictures of the 17 species in their habitats, and we hope that these illustrations will help in the identification and conservation of these taxa.

Keywords: endangered species, endemism, Espinhaço Range, Lamiales, Lantaneae

Scale bars: E–G = 1 mm. Photos: A–D by Pedro Henrique Nobre; E–G by Nádia Silvia Somavilla.

Class Magnoliopsida Brongn.
Order Lamiales Bromhead

Family Verbenaceae J.St.-Hil.

Genus Lippia L.

Lippia raoniana P.H.Cardoso & Salimena sp. nov.

Diagnosis: The new species is similar to Lippia spiraeastrum (Mart. & Schauer) T.R.S.Silva, but differs by ovate leaves (vs oblong or oblong-elliptic), slightly discolorous (vs strongly discolorous), matte adaxial surface (vs shiny), glandular abaxial surface (vs tomentose-glandular), shorter peduncle (0.8‒1.3 vs 3.2‒10.5 cm long) and slender (vs thick), ovate bracts (vs lanceolate). 

Etymology: The specific epithet is in homage to Raoni Metuktire, an important indigenous leader of Brazil, internationally known as a symbol of environmental preservation. Raoni is dedicated to the fight for the rights of native indigenous people and conservation of the tropical forest, mainly Amazonia. His legacy is a symbol of the daily struggle for Brazilian biodiversity, constantly threatened.

[Botany • 2022] Impatiens nimspurjae • A New Species of Impatiens and Updated Checklist of Balsaminaceae in Nepal


Impatiens nimspurjae Raskoti,   

in  Raskoti & Ale, 2022. 

Abstract
Impatiens nimspurjae (Impatiens, Balsaminaceae), a new species from Nepal is described based on molecular data and morphological characters. Notes on the diagnostic characters used to distinguish it from allied taxa are provided. I. nimspurjae is closely related with taxon belonging to sect. Racemosae (I. harae, I. radiata, I. wallichii, I. urticifolia) in having many-flowered racemose inflorescences, lateral sepals 2 (very rarely 4 with inner 2 reduced), capsule linear, seed ovoid, but differs by its sessile leaves, upper lobe of lower united petal not truncated, spur flattened at base. With the discovery of this new species and five species new records to Nepal, a checklist of Balsaminaceae having 57 species (8 endemic) in Nepal is updated. An identification key to the species of Imaptiens in Nepal is also provided.

Impatiens nimspurjae Raskoti: 
A. Flowering plant; B. Leaf; C. flower, side view; D. Dorsal petal (dorsal view); E. lateral united sepals (ventral view); F. lateral united sepals (dorsal view); G. Lateral sepal; H. Lower sepal; I. Ovary, pistil, pedicel and bract; J. Capsule; K. seeds.

 Line drawings assisted by Neera Joshi Pradhan.

Impatiens nimspurjae Raskoti, sp. nov.

Diagnosis: Impatiens nimspurjae is closely related to I. harae, I. radiata, I. wallichii but differ from these species by having sessile oblong-lanceolate leaves, flowers less than 3 in each peduncle, base of the spur flattened, apex of dorsal petal rounded, basal lobe of lateral united petal widely ovate, not truncated.

Etymology: The species epithet ‘nimspurjae’ refers to the name of Mr. Nirmal Purja (nickname Nimsdai) for his initiation on conservation through climate change champion. Mr. Purja is a world-renowned mountaineer from Nepal and has dozens of Guinness book world records in the field of mountaineering.

Distribution and habitat: Impatiens nimspurjae is known from the type locality in western Nepal where it occurs in the temperate forest and forest margins at an elevation range of 2800–2900 m. It grows on moist humus rich slopes.

Conclusions: 
With the discovery of this new species and five additional species new records to Nepal, a total 57 species of Impatiens (8 endemic species) were confirmed in the updated checklist of Balsaminaceae in Nepal. We strongly recommend that the future authors should integrate morphological and molecular data for the recognition and description of new species of Impatiens. Furthermore, we propose more robust studies (sampling population level) for the clarification of taxonomic position of I. bicornuta as well as taxonomic identity of its different polymorphic forms.

[Botany • 2022] Habenaria karstica (Orchidaceae) • A New Species of Habenaria and A Checklist of Orchidaceae from Limestone Outcrops of Brazil


Habenaria karstica J.A.N.Bat.,  

in Batista, Ferreira, Alves & Stehmann, 2022. 

ABSTRACT
Habenaria karstica J.A.N.Bat. sp. nov., a new species from limestone outcrops (i.e., karst) in the State of Minas Gerais, Brazil, is described. The new species is ecologically very distinct since it is the only Neotropical species of the genus that grows on limestone outcrops under full sun, associated with mat-forming saxicolous plants. It is morphologically similar to species of the Habenaria repens complex, and separation is only possible through a combination of morphological characters. Bayesian and parsimony phylogenetic analyses based on nuclear (rDNA ITS, ETS) and plastid (matK-trnK, rps16-trnK) DNA markers revealed that H. karstica belongs to H. sect. Spathaceae. The new species, however, differs in floral morphology from the other species in this clade. A survey of the literature and public plants datasets revealed 122 species and 58 genera of Orchidaceae in karsts of Brazil. Although small compared to the family’s diversity in the country, Orchidaceae is among the families with the highest number of species in some karst localities. Our results indicate that approximately 97% of Orchidaceae found in karsts of Brazil is not limited to limestone outcrops areas, and that species composition of each locality is primarily determined by the regional flora and the biome in which it is located.

Keywords: Brazil, Cerrado, karst, molecular phylogenetics, Orchidaceae

Habenaria karstica J.A.N.Bat. sp. nov.

Diagnosis: Similar in general morphology to some species in the Habenaria repens complex, but differs from these and all other Neotropical species of the genus for growing on limestone outcrops, under full sun, associated with saxicolous plants, and by the combination of the following characters: leaves not pleated, pedicellate ovary 19–25 mm long, petal anterior segment about the same length as the posterior segment (ratio 0.9–1.2), lip lateral segment about the same length as the median segment (ratio 0.9–1.0), spur 16–19 mm long, and rostellum mid lobe apex acute and erect. Distinct from the phylogenetically related species of the Habenaria sect. Spathaceae by the flowers completely green, pedicel 5–6 mm long, shorter than the ovary, pollinaria separate, and rostellum mid lobe completely held between the anther loculi.

Etymology: From the german ‘karst’ (limestone region), the specific epithet refers to the preference of this species for growing on limestone outcrops.

[Entomology • 2022] Pyrops buomvoi • The Lanternfly Genus Pyrops in Vietnam: A New Species from Central Vietnam, Taxonomic Changes, Checklist, Identification Key (Hemiptera: Fulgoromorpha: Fulgoridae)


Pyrops buomvoi  
Constant & Pham, 2022


ABSTRACT
A new species of the genus Pyrops Spinola, 1839 (Fulgoridae), Pyrops buomvoi sp. nov., is described from Ca Na, Ninh Thuan Province in Central Vietnam. It is attributed to the candelaria group and compared with the other species of the genus. Pyrops lathburii (Kirby, 1818) is proposed as a senior synonym of P. astarte (Distant, 1914), transferred back to the candelaria group from the pyrrhorhynchus group, and recorded from Laos for the first time. The candelaria and pyrorhynchus groups are defined and commented on. Intraspecific variation in the colour of the hind wings is recorded for the first time in Pyrops condorinus (Lallemand, 1960). A checklist of the 12 Vietnamese species of Pyrops and an illustrated key which can also be used for Laos, Cambodia and Southern Continental China, are given. Pyrops buomvoi sp. nov. is the first new species of Pyrops discovered in Indochina for more than 50 years. Intraspecific colour variation in the species of Pyrops is briefly discussed.

Pyrops buomvoi sp. nov.

Diagnosis: The species can be separated from all other species of Pyrops by the following combination of characters:(1) posterior wings milky white with apex and area along sutural margin black brown, with brown area paler and narrower towards basosutural angle (Fig. 1B);(2) cephalic process elongate and very slender, moderately curved dorsad (Fig. 1C–G);(3) head yellow with dorsum and sides of cephalic process reddish (Fig. 1);(4) tegmina with 3 irregular yellow bands on basal half, the two more distal ones formed from rows of elongate markings (Fig. 1B).

Etymology: The species epithet buomvoi is a Vietnamese name for the species of the genus Pyrops, with ʻ[con] buomʼ meaning ʻbutterflyʼ and ʻ[con] voiʼ meaning ʻelephantʼ. The name literally means ʻbutterfly-elephantʼ and is used as a name in apposition.

Abstract
 Freshwater brachyuran crabs in the limestone caves of northern and western Thailand were studied. Overall, 65 caves in nine provinces were investigated. The crabs obtained were referred to six species of six genera in two families. A checklist and the distribution of freshwater cave-dwelling crabs in Thailand and Southeast Asia are also provided. In Thailand at least 16 species of 14 genera in two families are recognized. On a broader scale, a total of at least 70 cave-dwelling crab species of 36 genera in three families are recorded in Southeast Asia. The majority are in the family Gecarcinucidae (14 genera, 43 species), followed by the families Potamidae (19 genera, 24 species) and Hymenosomatidae (3 genera, 3 species). The troglofaunal status for each species is also given. 

Key words: distribution, freshwater crabs, karst, Southeast Asia, subterranean environment, troglomorphy

สำหรับชนิดของปูน้ำจืดที่พบในถ้ำในประเทศไทย จากการรวบรวมรายงานการพบในปัจจุบันมีทั้งสิ้น 16 ชนิด จาก 14 สกุล และ 2 วงศ์ ส่วนใหญ่จะเป็นกลุ่มชนิดที่ประชากรโดยทั่วไปอาศัยอยู่ภายนอกถ้ำ แต่มีการปรับตัวเข้าไปใช้ถ้ำเป็นแหล่งหลบภัยและแหล่งหากิน โดยยังไม่ได้มีการปรับเปลี่ยนรูปร่างไปเป็นสัตว์ถ้ำแท้ (troglobite หรือ stygobite) โดยมีบางชนิดที่มีลักษณะที่ผ่านการวิวัฒนาการให้อาศัยอยู่ในถ้ำได้เป็นอย่างดีด้วยลักษณะของขาที่เรียวยาวมาก กระดองค่อนข้างแบน และมีด้านบนแบนราบ ได้แก่ ปูถ้ำอาจารย์ไพบูลย์ Phaibulamon stilipes ปูเขาหินปูนอาจารย์สุรพล Kanpotamon duangkhaei ปูถ้ำพิทักษ์ Thampramon tonvuthi, ปูเขาหินปูนสตูล Terrapotamon longitarsus และ ปูเขาหินปูนทุ่งหว้า T. thungwa ซึ่งอาศัยลักษณะพิเศษนี้ในการปีนป่ายหิน และแทรกตัวผ่านรอยแตกของหินปูนเข้าไปในถ้ำได้ ปูเหล่านี้ถูกจัดอยู่ในกลุ่มที่เรียกว่า troglophile หรือ stygophile ในชนิดของไทยดังกล่าวนี้ การค้นพบปูเขาหินปูนอาจารย์สุรพลนับเป็นการรายงานการพบครั้งที่ 2 หลังจากที่มีรายงานครั้งแรกเมื่อเมื่อปีพ.ศ. 2536 ส่วนภาพรวมในประเทศของเอเชียตะวันออกเฉียงใต้รวมที่พบในประเทศไทยสามารถรวบรวมรายชื่อปูน้ำจืดที่พบในถ้ำได้ทั้งสิ้น 70 ชนิด จาก 36 สกุล และ 3 วงศ์ โดยมีจำนวนชนิดที่พบในประเทศฟิลิปปินส์ และมาเลเซียประเทศมากที่สุดประเทศล่ะ 17 ชนิด ซึ่งนับว่าประเทศไทยก็มีรายงานจำนวนชนิดไม่แตกต่างกันมากนัก

อย่างไรก็ตามทั้งในประเทศไทยและประเทศเพื่อนบ้านยังคงมีแหล่งถ้ำหินปูนอีกมากมายที่ยังไม่ถูกสำรวจ หรือแม้แต่มีการสำรวจแล้วแต่ยังไม่ละเอียดทั่วถึงและไม่ครอบคลุมฤดูกาล ทำให้คาดว่ายังคงมีชนิดปูที่อาศัยในถ้ำตกสำรวจอีกหลายชนิด ทั้งที่เป็นปูถ้ำแท้และที่ใช้ถ้ำเป็นแหล่งพักพิงชั่วคราว การสำรวจและศึกษาวิจัยปูถ้ำของนายเรืองฤทธิ์ และผศ.ดร. โสภาค จึงยังไม่สิ้นสุดที่บทความตีพิมพ์ฉบับนี้ ล่าสุดจากการสำรวจอุโมงค์ที่ถูกขุดขึ้นในเขาหินปูนในจ.กาญจนบุรี ได้พบปูน้ำจืดที่มีลักษณะขาเรียวยาวเพิ่มเติมอีกชนิดภายในอุโมงค์ ซึ่งมีลักษณะแตกต่างจากชนิดที่พบได้ทั่วไปในพื้นที่เดียวกัน ขณะนี้อยู่ในระหว่างการตรวจสอบทางอนุกรมวิธานร่วมกับผู้เชี่ยวชาญด้านปูน้ำจืดชาวสิงคโปร์
