    [Herpetology • 2022] Cnemaspis samui & C. similan • Hidden Diversity of Rock Geckos within the Cnemaspis siamensis Species Group (Squamata: Gekkonidae): Genetic and Morphological Data from southern Thailand reveal Two New Insular Species and Verify the Ph

    Abstract
    Two new insular rock geckos in the genus Cnemaspis are described from Ko Samui in Surat Thani Province and Ko Similan in Phang-nga Province, southern Thailand, based on a combination of morphological and mitochondrial NADH dehydrogenase subunit 2 (ND2) data. Both new species represent divergent lineages within the Cnemaspis siamensis species group. Cnemaspis samui sp. nov. is distinguished from other species in the group by having eight or nine supralabial and infralabial scales; 5–8 pore-bearing precloacal scales in males, pores rounded; 25–27 paravertebral tubercles, arranged randomly; 22–25 subdigital lamellae under 4th toe; enlarged median subcaudal scale row present; gular region, abdomen, limbs and subcaudal region yellowish only in males, and uncorrected pairwise divergences of 8.86–26.83% from all other species in the C. siamensis species group. Cnemaspis similan sp. nov. is distinguished from other species in the group by having eight or nine supralabial and seven or eight infralabial scales; one pore-bearing precloacal scale in males, pore rounded; 24 or 25 paravertebral tubercles, arranged randomly; 23 or 24 subdigital lamellae under 4th toe; no enlarged median subcaudal scale row; pale yellow reticulum on head, neck, flanks, belly and limbs in male only, and uncorrected pairwise divergences of 9.34–27.11% from all other species in the C. siamensis species group. Cnemaspis samui sp. nov. is found along granitic rocky stream outcrops of Hin Lad Waterfall, Ko Samui, Gulf of Thailand, while Cnemaspis similan sp. nov. occurs in granitic rocky outcrops near Ao Nguang Chang Bay, Ko Similan, Andaman Sea. The phylogenetic analyses confirmed that C. chanardi and C. kamolnorranathi are also nested within the C. siamensis species group, as previously hypothesized from morphology and color pattern characters.

    [Botany • 2022] Echinosepala truncata (Orchidaceae: Pleurothallidinae) • A just Overtime Discovery: Another New Species of Echinosepala from Costa Rica


     Echinosepala truncata Pupulin, L.Álvarez & Bogarín, 

    in Pupulin, Álvarez-Alcázar & Bogarín, 2022. 

    Echinosepala truncata is described as new to science and illustrated from the holotype. It is compared with E. tomentosa, from which it differs by the sparsely lanate ovary, the narrowly obovate, apically rounded synsepal, the spathulate, apically and basally rounded petals, and the rectangular, apically truncate lip. The phylogenetic relationships of the new species could be hypothesized based on a shared set of morphological characters and geographic distribution.

    Species resembling Echinosepala tomentosa (Luer) Pridgeon & M.W.Chase in the habit and the shape and size of the flower, but easily distinguished bythe sparsely lanate ovary, obovate synsepal, spathulate and apically roundedpetals, and rectangular, apically truncate lip (see also Discussion). 

    Etymology. From the Latin truncatus, ‘truncate, having the end cut off’, in reference to the apex of the lip.

    [Entomology • 2022] Protosticta francyi • A New Species of Protosticta Selys, 1885 (Odonata: Zygoptera: Platystictidae) from the Brahmagiri Hills, Kerala, India


    Protosticta francyi  Sadasivan, Vibhu, Nair & Palot,  

    in Vijayakumaran, Nair, Samuel, Palot & Sadasivan, 2022.

    ABSTRACT
    A new species of  Protosticta Selys, 1885 is described from Brahmagiri hills of Coorg landscape of the Western Ghats in Peninsular India. The new species Protosticta francyi sp. nov., is a congener of  P. antelopoides Fraser, 1931 and  P. ponmudiensis Kiran, Kalesh & Kunte, 2015, occupying a similar microhabitat, but distributed north of the major biogeographical divide, the Palghat Gap. The new taxon is distinguished from all other Protosticta of  Western Ghats by the presence of long prothoracic spines in the males, the structure of the tip of the male cerci and genital ligula. A revised key to the species of  Protosticta of  Western Ghats is provided based on mature males.
