[Mammalogy • 2021] Uncovering Species Boundaries through Qualitative and Quantitative Morphology in the Genus Dasyprocta (Rodentia, Caviomorpha), with Emphasis in D. punctata and D. variegata



in Teta & Reyes-Amaya, 2021. 
 
Abstract
The genus Dasyprocta Illiger, 1811 includes at least 13 species of medium-sized caviomorph rodents, widely distributed from Mexico to northern Argentina. Despite being abundant, largely diurnal, and easily identifiable by their external traits, the taxonomy of this genus remains poorly understood. In this work, we reviewed the taxonomy of Dasyprocta along the Andes and adjoining lowland areas of the western Neotropics, including samples from Mexico to northern Argentina, with emphasis on two species largely confounded—sometimes considered as synonyms—during the last century: D. punctata Gray, 1842 and D. variegata Tschudi, 1845. In the construction of our taxonomic hypotheses, we use a purely morphological approach, emphasizing qualitative and quantitative cranial features and external traits (color patterns). The results of multivariate statistical analysis and differences in color patterns support the species-level validity of D. punctata and D. variegata. Within this latter nominal form, we also include those populations from northern Argentina and eastern Bolivia that recently were referred to D. azarae. Based on our results, D. punctata (including bellula, callida, candelensis, chiapensis, chocoensis, colombiana, dariensis, isthmica, nuchalis, richmondi, underwoodi, yucatanica, and zuliae) extends from southern Mexico to Colombia, Ecuador, northernmost Peru, and western Venezuela, while D. variegata (including azarae, boliviae, and yungarum) is distributed from south–central Peru and southwestern Brazil to Bolivia and northwestern Argentina.

El género Dasyprocta Illiger, 1811 incluye al menos 13 especies de roedores caviomorfos de tamaño mediano, ampliamente distribuidas desde México hasta el norte de Argentina. A pesar de ser abundantes, mayormente diurnas y fácilmente identificables por sus rasgos externos, la taxonomía de este género sigue siendo poco clara. En este trabajo, revisamos la taxonomía de Dasyprocta a lo largo de los Andes y tierras bajas adyacentes del Noeotrópico occidental, incluyendo muestras desde México hasta el norte de Argentina, con énfasis en dos especies largamente confundidas (a veces consideradas sinónimos) durante el siglo pasado: D. punctata Gray, 1842 y D. variegata Tschudi, 1845. En generar nuestra hipótesis taxonómica utilizamos exclusivamente métodos morfológicos, enfatizando características craneales cualitativas y cuantitativas, así como rasgos externos (patrones de color). Los resultados del análisis estadístico multivariado y las diferencias en los patrones de color respaldan la distinción a nivel de especie entre D. punctata y D. variegata. Dentro de esta última forma nominal incluimos las poblaciones del norte de Argentina y este de Bolivia que fueron referidas recientemente como D. azarae. Según nuestros resultados, D. punctata (incluyendo bellula, callida, candelensis, chiapensis, chocoensis, colombiana, dariensis, isthmica, nuchalis, richmondi, underwoodi, yucatanica y zuliae) se extiende desde el sur de México hasta Colombia, Ecuador, norte de Perú y oeste de Venezuela, mientras que D. variegata (incluyendo azarae, boliviae y yungarum) se distribuye desde el centro-sur de Perú y el suroeste de Brasil hasta Bolivia y el noroeste de Argentina.

Abstract
Symplocarpus koreanus (Araceae; Orontioideae) from Korea is described as new. Symplocarpus koreanus has long been considered to be conspecific with S. renifolius in Japan, but phylogenetic, morphological, and cytological data indicate its taxonomic distinction. Compared to S. renifolius, S. koreanus has a much smaller spathe and more spherical spadix with fewer, smaller flowers. Previous phylogenetic studies also suggested that S. koreanus is more closely related to nonthermogenic S. nipponicus than to S. renifolius in Japan. Like its nonthermogenic sister species, S. nipponicus, in Korea and Japan, S. koreanus is diploid (2n = 2x = 30), while S. renifolius in Japan is tetraploid (2n = 4x = 60). A detailed species description, geographical distribution, major morphological differences between the species and a dichotomous key to the species in eastern Asia are provided.

[Botany • 2021] Curcuma aruna & C. pitukii • Two New Species of Curcuma L. (Zingiberaceae) from northern Thailand


Curcuma pitukii Maknoi, Saensouk, Rakarcha & Thammar.,
 
in Maknoi, Saensouk. ... et Thammarong, 2021.

Abstract
 Curcuma aruna and C. pitukii, two new species from northern Thailand, are described, illustrated, and photographed. They are endemic to Sukhothai and Lampang Provinces, northern Thailand, and the morphological characteristics of two new species are compared with their closest species, C. flaviflora, C. eburnea, and C. pierreana. Two new species, C. aruna and C. pitukii are assignable to Curcuma subgenus Ecomata. C. aruna is recognized by leaves ovate with thin chartaceous, fertile bracts 6–12, it’s glabrous on nearly all parts of the plant, flowers yellow and labellum yellow with 2 darker yellow bands in the center. C. pitukii is recognized by bracts 20–40 with purplish white to purple, corolla lobes purplish white to pale purple, staminodes white, and labellum white with an embossed yellow path along the midrib from base to apex. A detailed description, distribution, ecology, etymology, preliminary conservation status, and photographs of two new species are provided. A key to 20 species of Curcuma subgenus Ecomata in Thailand is presented.

Curcuma aruna Maknoi & Saensouk, sp. nov. 
subgenus Ecomata 

This species is similar to C. flaviflora in early flowering habits, short peduncle, no coma and yellow flowers. The leaves of C. aruna are ovate and glabrous on both surfaces, instead of leaves elliptic to oblanceolate and pubescent on both surfaces in C. flaviflora. The length of the corolla tube of C. aruna is shorter than in C. flaviflora (2.3–2.8 cm long in C. aruna vs 3.8–4.2 cm in C. flaviflora). The staminodes of C. aruna are obovate, whilst those of C. flaviflora are ovate to elliptic. The staminodes of C. aruna are larger than those of C. flaviflora (2.2–2.6 × 1.4–1.6 cm in C. aruna vs 2.0 × 1.2 cm in C. flaviflora).

Etymology: The specific epithet of the new species is “aruna”, which means “dawn” in Thai, refer to flower color resemble the color of the dawn and name of God of the Dawn in Thai mythology. The name of the type locality province “Sukhothai” means the dawn of happiness also.
Vernacular name: Krachiao Arun - กระเจียวอรุณ

Curcuma pitukii Maknoi, Saensouk, Rakarcha & Thammar., sp. nov. 
subgenus Ecomata 

Curcuma pitukii is most similar to Curcuma eburnea Škorničk., Suksathan & Soonthornk. by its terminal inflorescence, the number of bracts, without coma bracts, and small filiform anther spurs. The leaves of C. pitukii are densely puberulent on the adaxial surface, but the leaves of C. eburnea are glabrous on the adaxial surface. C. pitukii has purplish white to purple bracts, whilst C. eburnea has cream-white or pale greenish bracts. The length of the calyx of C. pitukii is longer than in C. eburnea (14–18 mm long in C. pitukii vs 8–10 mm long in C. eburnea). The length of the corolla tube of C. pitukii is shorter than in C. eburnea (2.2–3 cm long in C. pitukii vs 3.5 cm long in C. eburnea). The corolla lobes of C. pitukii are purplish white to pale purple and sparsely puberulent at the apex, but in C. eburnea they are pure white and glabrous. The length of the filament of C. pitukii is longer than in C. eburnea (5–8 mm long in C. pitukii vs 2 mm long in C. eburnea). The length of the anther of C. pitukii is shorter than in C. eburnea (2.5–4 mm long in C. pitukii vs 8–9 mm long in C. eburnea).

Etymology: The specific epithet “pitukii” is named in honor of “Mr. Pituk Punyajun”, a supporter and backup plant taxonomists in Thailand for over 25 years and who first found the plant.
Vernacular: Cho Muang Pituk - ช่อม่วงพิทักษ์ 
(Cho in Thai name means inflorescence, Muang means purple, and Pituk is the first name of Mr.Pituk Punyajun).

Abstract
A new species of Dichaea sect. Dichaea from the Andean forests in Colombia is described and illustrated based on living material. Dichaea andina is compared with the morphologically similar D. lagotis and D. pendula, from which it can be distinguished by a number of vegetative and floral and features. Dichaea andina differs from D. lagotis in the broadly anchoriform lip, the hypochile transversely subrounded and the epichile transversely narrowly elliptic, briefly apiculate. Similarly, it differs from D. pendula in the caespitose habit, the leaves without cross-venation, and the inflorescence straight produced below the foliage, among other features. Ecological information for the new species is also provided.

Abstract
A new species and a rediscovery in the genus Saurauia (Actinidiaceae) from Zamboanga Peninsula, Mindanao island, Philippines are presented here. The new species, Saurauia abbreviata, closely resembles Saurauia lanaensis Merr. but can be differentiated by having longer petioles, uniformly setose adaxial leaf surface, longer and wider leaves, more lateral veins, 3 styles, and a 3(–4)-locular ovary. This discovery raises the current number of recognized Saurauia in the Philippines to 57 following an 87-year gap in the taxonomic study of this genus in the country. S. longipedicellata Merr. is also rediscovered after almost a century. A lectotype is here assigned for this name selected among the syntypes. Photographs, ecological notes, and an amended description are also provided to aid taxonomic identification.

Saurauia abbreviata K.R.Mazo, sp. nov. 
 
Diagnosis: Saurauia abbreviata closely resembles Saurauia lanaensis Merr. by having densely setose branchlets, abaxially setose leaves, small, axillary, cymose inflorescence; setaceous sepals; short sepals and petals. How-ever, the new species can be differentiated by having longer petioles (1.5–4.0 cm vs. 1.0–1.5 cm), uniformly setose adaxial leaf surface (vs. glabrous), longer and wider leaves (20–42 cm long × 9.5–17 cm wide vs. 11–20 cm long × 3.0–6.0 cm wide), more lateral veins (14–25 pairs vs. 10–12 pairs). In terms of floral characters, S. lanaensis has slightly larger petals and sepals vs. S. abbreviata. Notably, the older inflorescences in S. abbreviata forms a slightly thick woody rachis from which new flowers emerge after the senescence of the older ones—a characteristic not known to occur in S. lanaensis.

Etymology: The specific epithet abbreviata is derived from the Latin word “ brevis” (short) in reference to the very short or shortened inflorescences and flower dimensions of the new species—character combinations which are very rarely observed among Philippine Saurauia species.

We report a new species of the genus Micryletta from the montane evergreen forest in the Bidoup-Nui Ba National Park, Lam Dong Province, Langbian Plateau, southern Vietnam, based on molecular and morphological evidence. The new species is diagnosed by a combination of the following morphological characters: body size small (snout-vent length (SVL) 22.4 mm, single female); iris uniform black; snout nearly truncate in dorsal view, slightly rounded in profile; tibiotarsal articulation of adpressed limb reaching level of eye; dorsal surface smooth; supratympanic fold present, prominent; outer metatarsal tubercle absent; tips of toes very weakly dilated into small discs; finger webbing absent, toe webbing rudimentary; dorsal surfaces of head and body orange-red with small irregularly shaped dark-brown patches; dorsal surface of limbs pale dark brown with small reddish speckles; body flanks dark brown anteriorly fading to grayish brown posteriorly with brown spots in groin area; lateral sides of head immaculate blackish brown without white patches; coloration of ventral surfaces immaculate dark gray. The new species is divergent from all other congeners in 16S rRNA gene sequences (2.6%–5.8%). Following the IUCN Red List Categories and Criteria, we propose the new species be listed as Data Deficient (DD).






Micryletta melanops sp. nov. 

Chresonymy: Micryletta cf. inornata  — Poyarkov [Paiarkov] & Vassilieva (2011):
186–187, 211, Fig. 5.26.

Diagnosis: The new species is assigned to the genus Micryletta Dubois, 1987 based on the following morphological attributes: body size small; vomerine teeth absent; tympanum small, rounded, externally visible; subarticular tubercles on fingers and toes very prominent; three well-developed metacarpal tubercles; distinct supernumerary palmar and metatarsal tubercles posterior to base of digits; first finger not reduced; webbing on fingers absent and on toes rudimentary (Alhadi et al., 2019; Das et al., 2019; Dubois, 1987; Munir et al., 2020; Poyarkov et al., 2018; Yang & Poyarkov, 2021).

Micryletta melanops sp. nov. is distinguished from all congeners based on a combination of the following morphological characters: body size small (SVL 22.4 mm, single female); iris uniform black; snout truncate in dorsal view, nearly truncate in profile; tibiotarsal articulation of adpressed limb reaching eye level; dorsal surface smooth; supratympanic fold present, prominent; outer metatarsal tubercle absent; tips of toes weakly dilated into small discs; finger webbing absent, toe webbing rudimentary between toes II–III and III–IV; coloration of dorsal surfaces on head and body orange-red with small irregularly shaped brown patches; dorsal surface of limbs pale dark brown with small reddish speckles; flanks dark brown anteriorly, fading to grayish brown posteriorly with brown spots in groin area; lateral sides of head blackish brown, lacking white patches; coloration of ventral surfaces immaculate dark gray; tadpoles with distinct yellow blotches across tail and fin.

Etymology: Specific epithet “melanops” is an adjective in the nominative case derived from the Ancient Greek “melanos” for “black” and “ops” for “eye” and is given in reference to the characteristic uniform black iris coloration found in the new species.
 We recommend “Black-eyed Paddy Frog” for the common English name and “Nhái bầu mắt đen” for the common Vietnamese name of the new species.

Iris coloration in eleven species of the genus Micryletta.
A – Micryletta aishani (Sagaing, Myanmar); B – M. dissimulans (Songkhla, Thailand); C – M. erythropoda (Dak Lak, Vietnam); D – M. hekouensis (Yunnan, China);
E – M. immaculata (Hainan, China); F – M. inornata (North Sumatra, Indonesia); G – M. lineata (Nakhon Si Thammarat, Thailand); H – M. nigromaculata (Hai Phong, Vietnam);
 I – M. steinegeri (Taiwan, China); J – M. sumatrana (South Sumatra, Indonesia); K – Micryletta melanops sp. nov. (Lam Dong, Vietnam).

Abstract
A new species of striped Ichthyophis is described from Mizoram State of northeast India. For its distinguishing features, Ichthyophis benjii sp. nov. has narrow (W/S >5) irregular faint lateral yellow stripes extending immediately from corner of the mouth to the level of the posterior vent, not contacting the disc, barely or not visible on the collars ventrally, patchy in the trunk region; known to attain lengths greater than 400 mm, 26 < L/W < 30; head V-shaped, short (L/H > 24); TAs (tentacular apertures) more than twice as far from nares as from eyes (TN/TE > 2); C2 (second collar) noticeably longer than C1 (frst collar). It differs from all other striped congeners, except for I. tricolor and I. multicolor, in having an indistinct pale yellowish lateral stripe that is bordered by a darker ventrolateral longitudinal stripe immediately above the pale venter on each side. It differs from I. tricolor and I. multicolor in having more AGs (annular grooves) 388–422 counted dorsally; and in having 118–124 vertebrae vs. < 120 (I. tricolor) or > 125 (I. multicolor). An analysis of mitochondrial 16s rRNA shows Ichthyophis benjii sp. nov. to be a sister taxon to I. multicolor with an uncorrected p-distance of 0.055. At present, due to the lack of data on the population status and range of distribution, we propose the species be considered as Data Defcient (DD) under the IUCN Red List criteria.

Ichthyophis benjii sp. nov.
 
Diagnosis. Ichthyophis with narrow (W/S > 5) irregular faint lateral yellow stripes extending from immediately behind CMs to the level of the posterior of vent, not contacting the disc, barely or not visible on the collars ventrally, patchy in the trunk region; known to attain lengths greater than 400 mm, 26 < L/W < 30; head more V-shaped than U-shaped in dorsal view, short (L/H > 24); TAs more than twice as far from nares as from eyes (TN/TE > 2); without distinctive moustache-like stripes between snout tip and TAs; and C2 noticeably longer than C1. Ichthyophis benjii sp. nov. differs from all other striped congeners in having a markedly less prominent pale yellowish lateral stripe, bordered by a darker ventrolateral longitudinal stripe immediately above the pale venter on each side. It can be differentiated from I. tricolor and I. multicolor in having much higher AGs of 385–422 and 383–423 counted dorsally and ventrally, respectively.

Etymology. The species epithet “benjii” is dedicated in memory of Benjamin Lalremsanga (1988–2020, nephew of Hmar Tlawmte Lalremsanga) who used to actively assist the author(s) in their herpetofaunal surveys. 
Suggested English common name: Benji’s Caecilian

Paratypes of Ichthyophis benjii sp. nov. in life: (A) MZMU 1462 from Chhinga Veng, (B) MZMU 1481 from Tanhril, (C) MZMU 2025 from Gosen,
