| 2:10a | [Ichthyology • 2022] On the Identity of the Banded Gourami Trichogaster fasciata (Perciformes: Osphronemidae) with Notes on the Taxonomic Status of Trichopodus bejeus
Abstract Based on its original description and putative topotypes, the identity of the banded gourami Trichogaster fasciata is resolved. Trichogaster lalia is a synonym of T. fasciata, and the name Trichogaster bejeus is applied to the species hitherto identified as T. fasciata. T. fasciata is distinguished from its congeners in the shape of caudal fin, colouration, lip morphology and meristic and mensural characters. Keywords: Colisa gourami, Osphronemidae, taxonomy, Trichogaster fasciata, Trichogaster lalia, Trichogaster bejeus

| 10:28a | [Paleontology • 2022] Boreognathus pogorevichi • A Remarkable New polychaete annelid from the lower Permian of the Pechora Basin, Russia
Abstract The sclerotized jaw elements (scolecodonts) of polychaete annelids are rarely preserved as articulated jaw apparatuses. Here we describe a morphologically unusual, rather large, and symmetrical jaw apparatus, assigned to the new taxon Boreognathus pogorevichi gen. et sp. nov., from the Kungurian (lower Permian) of the Pechora Coal Basin, northern Cis-Urals, Russia. Whereas the specimen is mainly preserved as a three-dimensional external mould of the near-complete dorsal maxillary apparatus, some organic matter comprising the original jaw wall is also retained. The new taxon combines edentate, pincer-like first maxillae (MI) typical of the extant Labidognatha apparatus type with long slender carriers common in the Prionognatha type. Unlike the smooth MI, MII are consistently and prominently denticulated. The new genus represents a hitherto unknown type of polychaete jaw apparatus and is assigned to the Palaeozoic family Atraktoprionidae.

| 10:44a | [Botany • 2020] Paraphlomis kuankuoshuiensis (Lamiaceae) • A New Species from the Limestone Areas of northern Guizhou, China
Abstract Paraphlomis kuankuoshuiensis (Lamiaceae), a new species found in the limestone areas of northern Guizhou, China, is described and illustrated in this paper. Based on its tubular-campanulate calyx, this taxon should be a member of sect. Paraphlomis Prain. The new species resembles P. patentisetulosa C.Y. Wu & H. W. Li, P. hispida C.Y. Wu, and P. hirsutissima C.Y. Wu & H.W. Li, but differs from these three taxa in the following aspects: the stems are very short (<7 cm), with one or two short internodes, giving the impression of having a tuft of basal leaves; it has sparsely setose hairs on the outer surface of the calyces and short fruiting calyces. The florescence, fruit period, habitat, and the geographical distribution of P. kuankuoshuiensis are also quite different from the three closely related species.

  Paraphlomis kuankuoshuiensis R.B.Zhang, D.Tan & C.B.Ma, sp. nov. Diagnosis: Paraphlomis kuankuoshuiensis can be distinguished from the morphologically similar species P. patentisetulosa, P. hispida, and P. hirsutissima by its very short stem (< 7 cm) with one or two short internodes (giving the impression of having a tuft of basal leaves). The three closely related species have stems longer than 15 cm and more internodes. The new species has sparsely setose hairs on the outer surface of the calyces (vs. finely or densely) and short fruiting calyces (5-6 cm vs. 7 cm, 8-9 cm, and to 11 cm). There are some other diagnostic characters between the new species and its three closely related species (Table 1). The flowering from July to August and fruiting from August to September are quite different from the three species (vs. fruiting from November to January). It grows on bare steep rocks, which is a distinctive habitat. The new species distributes in Guizhou Province and is far away from the other three species (Fig. 3). Etymology: The specific epithet ‘kuankuoshuiensis’ is derived from the plant’s locality: Kuankuoshui National Natural Reserve, Guizhou Province, China.
