[Herpetology • 2021] Calamaria alcalai • A New Species of Reed Snake, Genus Calamaria (Colubridae: Calamariinae), from Mindoro Island, Philippines
 | Calamaria alcalai
Weinell, Leviton & Brown, 2021
Philippine Journal of Systematic Biology. 14(2). |
Abstract We describe a new species of reed snake of the genus Calamaria Boie 1827, from Mindoro Island, Philippines. The new species differs from all other species of Calamaria by having the following combination of characters: a high number of subcaudal scale pairs (> 40 in males, > 30 females) and ventrals + subcaudals (> 205 in males, > 210 in females); mental scale not contacting chin shields; dorsal surface of head, body, and tail uniformly dark brown; and ventral surface of body (extending to include part or all of first longitudinal row of dorsals) uniformly pale (yellow or white in life). The new species is likely most closely related to Calamaria schlegeli Duméril, Bibron, and Duméril 1854, which also has a high number of subcaudal scales compared to other Calamaria species. The new species is the second Calamaria species known from Mindoro Island and the eighth known from the Philippines, and its presumed distant relationship from other Philippine Calamaria suggests an additional colonization of the Philippines by this genus from continental Asia.

Diagnosis: The new species differs from all other southeast Asian species by having the following combination of characters: prefrontal scales large, bordering rostral scale; internasal scales absent; 13 longitudinal rows of dorsal scales throughout length of body; subcaudal scales > 30 pairs (females), > 40 pairs (males); mental scale not in contact with chin shields; preocular scale present; prefrontal scale not in contact with eye. Color pattern in life: dorsal surface of head, body, and tail maroon or light maroon; ventral surface of head and anterior of body yellow; ventral surface of posterior of body and tail pale cream; boundary between dorsal and ventral body coloration on first longitudinal row of dorsal scales light yellow to cream. Color pattern in ethanol: dorsal surface of head, body, and tail uniformly dark brown; ventral surface of head, body, and tail pale yellow or cream.
Etymology: The species epithet alcalai is a patronym in the genitive singular, honoring Dr. Angel C. Alcala, for his numerous contributions on the systematics, biogeography, and ecology of amphibians and reptiles of the Philippines—and, in general, for his influential promotion of conservation and sustainable management of the archipelago’s terrestrial and marine biodiversity.

Gray shading indicates areas ~ 120 m below sea level that are presumed to have been exposed land during Pleistocene glacial maxima, and represent the hypothesized limits of Pleistocene Aggregate Island Complexes (PAICs), including the distinct Mindoro PAIC, which encompasses small islands to the south; light blue color indicates large, present day lakes.

[Botany • 2021] Curcuma lithophila & C. rufostriata (Zingiberaceae) • Two New Species from Thailand, and Additional Notes on C. papilionacea
 | Curcuma lithophila Škorničk. & Soonthornk.
in Soonthornkalump, Pungpairote, Niwesrat & Skornickova, 2021. |
ABSTRACT Curcuma lithophila and C. rufostriata, two new species from Curcuma subgen. Hitcheniopsis, are described and illustrated. They are compared with their morphologically closest species, Curcuma rhabdota, C. papilionacea and C. sparganiifolia. Notes on distribution, ecology, etymology, uses and IUCN provisional assessments are provided. Further notes on the distribution of the recently described C. papilionacea and an improved IUCN conservation assessment are reported from additional collections.
Keywords: Curcuma rhabdota, Curcuma papilionacea, Curcuma subgen. Hitcheniopsis

Curcuma lithophila Škorničk. & Soonthornk., sp. nov. (subgen. Hitcheniopsis)
Similar to Curcuma rhabdota Sirirugsa & M.F.Newman in overall habit, colour of the flowers,and spurless anther but differs in the lack of comabracts, bracts without prominent red-brown striation,and lateral staminodes broadly obovate and broaderthan the labellum (versus prominent coma bracts, bracts with prominent striation and lateral staminodeselliptic and much narrower than the labellum in C. rhabdota).
