| 12:08a | [Botany • 2021] Allium muratozelii (Amaryllidaceae) • A New Species of Allium sect. Melanocrommyum from eastern Anatolia, Turkey
Abstract Allium muratozelii is described here as a new species. Diagnostic morphological characters, a full description, and detailed illustrations are given. Allium muratozelii is known from Tunceli province in eastern Anatolia, Turkey. According to its morphological features, the new species belongs to Allium subg. Melanocrommyum sect. Melanocrommyum. It is distinguished from the morphologically similar A. colchicifolium mainly by scape and leaf length, leaf shape, margins of tepal, and filament color. IUCN red list category, notes on biogeography and ecology of the new species are also given. Keywords: Allium bischoffii, A. haussknechtii, A. straussii, A. sect.

| 10:52a | [Botany • 2021] Polycarpaea palakkadensis (Caryophyllaceae) • A New Species from Kerala, South-West India
Abstract Polycarpaea palakkadensis, a new species of Caryophyllaceae from the hillocks of Palakkad District (Kerala, India) is described and illustrated. P. palakkadensis is morphologically similar to P. rangaiahiana from which differs in having fused ovate bracts, capilliform bracteoles, linear stipules, ovate-cordate petals, filaments much shorter than anther, capsule with 1–2 ovoid elliptical seeds. Keywords: Caryophyllales, Western Ghats, Palakkad gap, Eudicots

| 1:25p | [Diplopoda • 2022] Malayorthomorpha halabala & M. hulutbeeda • Review of the Millipede Genus Malayorthomorpha Mršić, 1996 (Diplopoda: Polydesmida: Paradoxosomatidae), with Descriptions of Two New Species from Thailand and A Key to its Species
Abstract The millipede genus Malayorthomorpha Mršić, 1996, so far monospecific and previously known only from Park Belum, Perak State, northern Malaysia, is recorded from a mountain in Betong District, Yala Province, southern Thailand for the first time, being represented there by two new species: M. halabala sp. nov. and M. hulutbeeda sp. nov. Both new species are found to occur syntopically and can be assumed as narrowly endemic to the Titiwangsa Mountain Range which begins in southern Thailand, crosses the Malaysian border, and extends into east and west coast regions of the Malay Peninsula. In addition, the generic diagnosis is slightly updated, and a key to all three species is provided. Keywords: Malaysia, Malayorthomorpha halabala sp. nov., Malayorthomorpha hulutbeeda sp. nov., Orthomorphini, taxonomy Family Paradoxosomatidae Daday, 1889 Subfamily Paradoxosomatinae Daday, 1889 Tribe Orthomorphini Brölemann, 1916 Genus Malayorthomorpha Mršić, 1996
Malayorthomorpha halabala sp. nov. Diagnosis: This new species seems to be particularly similar to M. siveci Mršić, 1996, with which it shares most of the gonopodal characters. It differs from M. siveci by the wider body, 2.7–3.2 mm (vs smaller, 1.2 mm), the colour pattern which is uniformly red brown with lighter red brown paraterga (Fig. 3A–F) (vs a light brown body with the collum and caudal edges of metazonae margined darker brown; Fig. 1A), as well as the pleurosternal carinae present until segment 11 (vs until segment 5), the sternal lobe between ♂ coxae 4 with a pair of small cones laterally near base (Fig. 3E, H, I) (vs absent, Fig. 1D), and the tip of the gonopod with a denticulate margin (Figs 4A, B, 5C, D) (vs smooth and rounded; Fig. 1E–G). Etymology: To emphasize Hala-Bala Wildlife Sanctuary, the type locality. Noun in apposition.
Malayorthomorpha hulutbeeda sp. nov. Diagnosis: This new species is distinguished from its two congeners in sternal process between male coxae 4 linguiform with a rounded tip, and lamina lateralis of gonopodal solenophore triangular, apically bifid and protruded laterally. Etymology: To emphasize “hulutbeeda” which means “flat-back millipede” in Malay dialect, a noun in apposition. A Malay dialect language is mainly used in three provinces of southern Thailand where the holotype was obtained. Remark: This species was found living together with M. halabala sp. nov. Moreover, according to our observations, they may even occur syntopically, sharing the same habitat: leaf litter surface, branches of trees and tree trunks. Natdanai Likhitrakarn, Sergei I.

| 1:48p | [Paleontology • 2022] Bisticeratops froeseorum • A New Chasmosaurine Ceratopsid from the Upper Cretaceous (Campanian) Farmington Member of the Kirtland Formation, New Mexico
A nearly complete skull of a new ceratopsid dinosaur, Bisticeratops froeseorum, is described from the Farmington Member of the Kirtland Formation (late Campanian, Upper Cretaceous) of New Mexico. Bisticeratops is distinguished by several diagnostic cranial characters, including those of the premaxilla (stepped dorsal margin), maxilla (short jugal process lacking the ventral pocket-like fossa), jugal (short maxillary process of the jugal), and palpebral ornamentation (short with moderate ornamentation). It differs from other known chasmosaurines, especially from stratigraphically older species in the same geographic region, Pentaceratops sternbergi and Titanoceratops ouranos, by a strongly reduced jugal process of the maxilla and an unusual maxilla/jugal contact, which forms a shallow, triangular-shaped lateroposteriorly concave sulcus. A phylogenetic analysis recovers Bisticeratops froeseorum as sister species to the unnamed Almond Formation chasmosaurine and as a member of a potentially new southern clade of chasmosaurines, outside the Triceratopsini, and distinct from other southern Laramidian chasmosaurines such as Pentaceratops. The dinosaur fauna of the Farmington Member is comparatively poorly understood, especially compared to stratigraphically older faunas in the San Juan Basin. Therefore, the new, presumably rare species Bisticeratops froeseorum, together with several recently named and described chasmosaurines such as Navajoceratops sullivani, Sierraceratops turneri, and Terminocavus sealeyi, add to the diversity and disparity of chasmosaurines and provides further support for latitudinal variation in the ceratopsid fauna during the Late Cretaceous interval in the Western Interior Basin of North America.
