Drosera margaritacea T.Krueger & A.Fleischm., sp. nov. 

Diagnosis:—Drosera margaritacea is morphologically similar to Drosera finlaysoniana Wall. ex Arn. in Hook. from which it differs (contrasting characters in parentheses) by its petiolate leaves, borne on a 1.5–3.5 mm long petiole (leaves sessile), petiole covered with 20–50 stalked secretive glands 0.10–0.40 mm long with a multicellular stalk and translucent milky white, hemispherical to depressed ovoid gland head 0.10–0.30 mm in diameter that remains present even in dried material (petiole absent), stem, leaves, peduncle, pedicels and sepals covered with 0.05–0.30 mm long stalked capitate trichomes with uniseriate stalk and yellow, spherical, non-secretory gland head ca. 0.05 mm in diameter (stem, abaxial leaf surface, peduncle, pedicels and sepals covered with 0.1–0.3 mm long secretory capitate trichomes with uniseriate stalk and flattened gland head secreting a translucent mucilage droplet 0.1–0.2 mm in diameter), T-or Y-shaped trichomes absent (adaxial leaf bases and margins covered with 0.05–0.40 mm long T-or Y-shaped trichomes), inflorescence (20–)30–55(–65) cm long, with at least 30–50 flowers, its peduncle held upright, ± parallel to stem and much exceeding the carnivorous leaves (inflorescence (3–)6–18(–26) cm long, (2–)6–20(–26)- flowered, peduncle usually horizontal [this character is typically very obvious in live specimens, but sometimes not easily discerned in pressed herbarium material], shorter than or at most equalling the leaves in length), flowers 18–24 mm in diameter (7–14(–20) mm in diameter), stamen connective longer than filament, shorter than thecae and with rounded yellow tip ca. 0.2–0.4 mm in diameter (stamen connective usually much shorter than filament, as long as the thecae, lacking a rounded yellow tip).

Etymology:—The species’ epithet (from Latin margaritaceus = pearly, pearl-bearing) refers to the indumentum of unique, stalked secretive glands with translucent milky white, hemispherical to depressed ovoid (pearl-like) gland heads, as well as to the characteristic swollen, roundish (pearl-like) apical dilatation of the anther connective.

[Herpetology • 2021] Eutropis alcalai • A New Species of Sun Skink (Scincidae: Eutropis) from the Zamboanga Peninsula, southwestern Mindanao Island, Philippines

Eutropis alcalai  
Barley, Sanguila & Brown, 2021

Alcala’s Rough-scaled Sun Skink || 

We describe a new species of lizard in the genus Eutropis Fitzinger 1843 from the southwestern tip of the Zamboanga Peninsula on the western part of Mindanao Island, Philippines. The new species is related to Eutropis rugifera, which is a secretive, forest-adapted skink that ranges widely outside the Philippines from the western extent of its distribution on Nicobar Island (the type locality) through southern Peninsular Malaysia, Sumatra and the Mentawai islands, Borneo, Java, and as far east as Bali Island. The discovery of a new, morphologically distinct, and genetically highly divergent Sun Skink lineage in the low elevation forests of Zamboanga Peninsula creates a puzzling disjunct geographic distribution (E. rugifera has not been reported from the Sulu Archipelago). The new species is estimated to have diverged ~10–16 mya from E. rugifera, from which it appears to have an extralimital and isolated distribution. Considering the dynamic geological history and ancient continental origin of the Zamboanga Peninsula, colonization by the new species may have been facilitated by pre-Pleistocene overseas long-distance dispersal, saltatory range expansion and subsequent contraction/extinction in the Sulu Archipelago, and/or possibly paleotransport on the ancient crustal fragment of Zamboanga. The new species is known only from Zamboanga City’s primary surface water supply catchment at the lowest elevations inside the boundaries of Pasonanca Natural Park, despite the fact that there have been historical surveys of herpetological diversity at multiple sites to the northeast (Zamboanga, western Mindanao) and to the southwest (Sulu Archipelago). The new species, thus, may be limited to just the tip of the Zamboanga Peninsula, possibly rendering Pasonanca’s low elevation forests its most critical habitat resource for long term persistence and survival of the species.

Eutropis alcalai sp. nov. 

Diagnosis.— Eutropis alcalai sp. nov. can be distinguished from its closest relative, E. rugifera, by its smoother head scales, with light embossing only, and keels limited to posterior margins of parietals, temporals and nuchals (vs. rugose to strongly keeled in E. rugifera), by absence (vs. presence) of contact between the postmental and second infralabial, by the presence of 29–32 (vs. 21–26) subdigital lamellae under the 4th toe, by the presence of seven infralabials (six in E. rugifera), the presence of differentiation in the precloacal scales series (two, medial precloacals enlarged, transversely expanded and bordered on either side by two undifferentiated scales) in E. alcalai sp. nov. (vs. six equal sized scales in E. rugifera), by equivalent length of 3rd and 4th fingers (vs. 4th finger longer than 3rd), and by its white chin and infralabial scales (vs. yellow to orange in E. rugifera).

Distribution.— This species is only known from Pasonanca Natural Park near Zamboanga City at the southwestern tip of the Zamboanga Peninsula. A closely related species (E. rugifera) occurs on Borneo (among other islands of the Sunda Region), and although neither species has been collected from the Sulu Archipelago, one of them may occur on its larger islands.

Etymology.— We take great pleasure in naming this distinctive new species for our colleague Angel C. Alcala, in recognition of his numerous foundational contributions to the natural history, systematics, ecology, and conservation of Philippine lizards of the family Scincidae (Alcala and Brown 1966, 1967; Alcala 1970; Brown and Alcala 1956, 1961, 1963a,b, 1980, 1986). Suggested common name: “Alcala’s Quinque-carinate (Five-keeled) Sun Skink,” or “Alcala’s Rough-scaled Sun Skink.”

[Botany • 2021] Gastrodia longiflora (Orchidaceae, Epidendroideae: Gastrodieae) • A New Mycoheterotrophic Species from Ishigaki Island, Ryukyu Islands, Japan

 Gastrodia longiflora Suetsugu

in Suetsugu, 2021.

Gastrodia Brown (1810: 330; Gastrodieae, Epidendroideae) is a mycoheterotrophic orchid genus distributed in temperate and tropical regions of Asia, Oceania, Madagascar, and Africa (Cribb et al. 2010, Hsu & Kuo 2010, Suetsugu et al. 2018). It is characterized by fleshy tubers, absence of normal leaves, united sepals and petals and two mealy pollinia without caudicles (Cribb et al. 2010, Hsu & Kuo 2010, Hsu et al. 2012, Suetsugu et al. 2018).

Several recent studies have re-examined the diversity of Gastrodia in many Asian countries. Consequently, the genus comprises more than 100 species, making it the most species-rich mycoheterotrophic genus (Suetsugu et al. 2018a,b, Suetsugu 2019). However, species diversity of Gastrodia likely remains underestimated due to its brief flowering season and dwarf habit. As anticipated, an unknown Gastrodia species was discovered during a recent botanical survey on Ishigaki Island, Japan. A remarkably long, narrow perianth tube shows a close affinity to G. nipponica (Honda, 1932: 168) Tuyama (1939: 4). Accordingly, this plant is described here as a new species and a detailed morphological account is provided.

Gastrodia longiflora is similar to G. nipponica but differs by its perianth tube that is relatively narrower for its length and hemiellipsoid anther cap. 

Distribution and phenology:— Restricted to the type locality, where dozens of flowering individuals occur in a dense forest dominated by Castanopsis sieboldii (Makino, 1909: 141) Hatusima (1971: 223). Flowering was observed from mid-February to mid-March, and fruiting from late-March to early-April.

We describe Dixonius mekongensis sp. nov. from sandstone formations in Khong Chiam District, Ubon Ratchathani Province, in extreme eastern Thailand along the Laotian border. The new species differs from all currently recognized Dixonius by the following combination of morphological characters and pattern: maximal known snout-vent length of 51.2 mm; 16 longitudinal rows of dorsal tubercles; 32 to 34 paravertebral scales; 22 to 24 longitudinal rows of ventral scales across the abdomen; seven precloacal pores in males, no pores in females; a marked canthal stripe; and a spotted to uniform dorsal pattern. This description brings the number of Dixonius species to 13, with six species endemic to Thailand.

Impatiens subfalcata is easily recognised by its slightly falcate and lanceolate or oblanceolate leaves (length-to-width ratio, 4.6–7.6). In Laos, it is similar to Impatiens attopeuensis Hook.f. in its habit, serrate leaf margins and pinkish purple corolla, but distinguished not only by its slightly falcate leaves but also by its more numerous secondary veins (8–10 pairs in I. subfalcata versus 5–7 pairs in I. attopeuensis), shorter petioles (subsessile to 0.2 cm long versus 0.5–2 cm long), shorter spur (2.1–2.6 cm versus 4–7 cm long), and smaller dorsal petal (6–7 mm versus 12–14 mm).

Distribution. Laos, Champasak Province, Dong Hua Sao National Protected Area (Bolaven Plateau), 1147 m elevation.

Habitat and ecology. Impatiens subfalcata grows on dripping rocky walls at a waterfall.

Etymology. The species epithet, subfalcata, is derived from the slightly falcate nature of the leaves of this species.

Vernacular name. ທຽນໃບດາບ (thien bai dab), suggested here; in Lao, thien means Impatiens species and bai dab means ‘falcate leaf’.
