| 9:56a | [Entomology • 2019] Cucujus costatus • Contribution to the Knowledge of the Genus Cucujus Fabricius (Coleoptera, Cucujidae) from China
Abstract Cucujus costatus Zhao & Zhang, new species is described from Guangdong, China. This new species can be easily recognized by the longitudinal elevated carinae on elytra and its strongly convex eyes. Additional records for C. kempi Grouvelle, 1913 and C. elongatus Lee & Pütz, 2008 are added. A key to the known Chinese species of Cucujus Fabricius is given. Keywords: Coleoptera, saproxylic beetles, Oriental region, Xizang, Cucujoidea, flat bark beetles
Cucujus costatus Zhao & Zhang, new species Etymology. The name refers to the peculiar character of the elevated carinae on the elytra. Ming-Zhi Zhao and Jin-Kun Zhang. 2019. Contribution to the Knowledge of the Genus Cucujus Fabricius (Coleoptera, Cucujidae) from China. Zootaxa. 4544(1); 144-150. DOI: 10.11646/zootaxa.4544.1.10 | ||||||
| 2:10p | [Botany • 2019] Senyumia granitica (Gesneriaceae) from Johor, Malaysia, the Second Species of Senyumia
Abstract The genus Senyumia was previously known from a single species, S. minutiflora (Ridl.) Kiew, A.Weber & B.L.Burtt, from a limestone karst, Gunung Senyum, in Pahang, Malaysia. Senyumia granitica Kiew, here described and illustrated, is the second species of the genus. It differs from S. minutiflora, not only in its habitat, but also in its shorter leaves, larger, non-resupinate or only partially resupinate flowers and smaller seeds. It is known from a small, fragmented population from a low range of hills. Therefore, under the IUCN Red List Categories & Criteria, it is assessed as Critically Endangered. Keywords: New species, Senyumia granitica, Senyumia minutiflora, ecology, conservation
Senyumia Kiew, A. Weber & B.L. Burtt. Senyumia Kiew, A. Weber & B.L. Burtt. Beitr. Biol. Pflanzen 70 (1998 [1997]) 400; Weber, Fam. & Gen. Vasc. Pl. 7 (2004) 148. Type species: Senyumia minutiflora (Ridl.) Kiew, A. Weber & B.L. Burtt. Distribution: Two species, both endemic in Peninsular Malaysia. Ecology: Lithophytic, growing in cracks and crevices in light shade either on quartz derived from granite or on limestone rocks.
Senyumia granitica Kiew, sp. nov. Diagnosis: This new taxon resembles Senyumia minutiflora in its wiry, woody stem; tufted leaves with an elliptic lamina with a non-cordate base; small, white flowers and orthocarpic, strongly twisted capsule. However, the new species differs from Senyumia minutiflora in its shorter leaves that are less than 1.5 times longer than wide, flowers that are not resupinate or are partially resupinate, have a longer corolla tube and lobes of the lower lip that are flat and not reflexed and the much smaller seeds (Table 1). ... Distribution: Peninsular Malaysia, Johor, Ledang District, endemic on Bukit Reban Kambing and Bukit Tukau, on an isolated low range of granite hills from 200–500 m elevation, west of the southern tip of Gunung Ledang (formerly known as Mt Ophir). Etymology: From its habitat, it grows in cracks in quartz rocks derived from the granite bedrock, in contrast to Senyumia minutiflora that is restricted to growing on limestone rocks.
