In broadening the understanding of the diversity, distribution and seasonality of gelatinous zooplankton of Sri Lanka, a survey (‘Waya-jel-Survey’) was carried out in coastal waters of the country from 2016 to 2020, and the collected specimens of pelagic tunicates were taxonomically identified. Further, a comprehensive literature survey was conducted and the previous records on the occurrences of pelagic tunicates within the exclusive economic zone of Sri Lanka were cross-checked and listed in developing the first-ever annotated checklist. Among the samples collected in this study, Pyrostremma spinosum and Thalia sibogae were reported for the first time from Sri Lankan waters while two more thaliaceans, i.e., Doliolum denticulatum and Pegea confoederata, and six appendicularians, i.e., Fritillaria borealis sargassi, F. formica digitata, Oikopleura cophocerca, O. fusiformis, O. longicauda, and O. rufescens were re-recorded. In total, forty species (including two subspecies) in 19 genera, belonging to five families from four orders of the classes Appendicularia (n = 17 species) and Thaliacea (n = 23 species) were reported to be inhabited in Sri Lankan waters. Most of the records were from the Laccadive Sea region while the majority of the species have been reported during the northwest monsoon (December to February) period.

Larval food plants (LFPs) of Sri Lankan butterflies have been well documented recently with the aid of studies done by numerous researchers.  In this paper, we present further records, 118 LFPs used by 83 butterflies and 145 plant-butterfly combinations.  LFPs of Lethe dynsate and Potanthus pseudomaesa pseudomaesa are reported for the first time in Sri Lanka.  Important observations, possible LFPs and LFP preferences of rare and threatened butterfly species, are discussed.  This information on plant-butterfly interactions will play an important role in conservation management of both plant and butterfly species.

Fifteen new genera of cheilostome Bryozoa are described from the New Zealand biogeographical region, centred on Zealandia, between 29° and 59°S latitude from shallow coastal waters to abyssal depths. The new genera are:Cavelliella,Mangana,Recapitulator(Calloporidae),Microblestrum,Stolomicropora(Pyrisinellidae),Otomicropora,Rosemariella(Microporidae),Bioptica,Caesiopora(Romancheinidae),Cheilonellopsis(Lacernidae),Xenogma(Buffonellodidae),Bountyella(incertae sedis),Taylorius(Escharinidae),Fovoporella(Schizoporellidae) andRamicellepora(Celleporidae). Several new combinations are also recognized, i.e.Corbulella fossa,Fovoporella spectabilis,Kenaplousina canariensis,Taylorius incognitus,Taylorius masoni,Taylorius waiparaensisandXenogma rhomboidale. Ten of the new genera are nominally endemic to the New Zealand exclusive economic zone.RecapitulatorandMicroblestrum(on seamounts near the southern part of the Hjort Trench) andRosemariella(seamount in the Louisville Ridge) occur in extraterritorial waters,Xenogmaextends to Australia andTayloriusextends to South Africa.Tayloriusis also known from the Miocene andFovoporellafrom the Pliocene.RecapitulatorandManganahave plesiomorphies that are novel among Recent Calloporidae (respectively a costate ooecium and ‘pelmatoporine’ elongate adventitious interzooidal kenozooids) but which are found in some Cretaceous calloporids or cribrilinids.

Introduction. Hypoparathyroidism, which is a common complication following total thyroidectomy can be transient in majority and permanent in 1.5% of the patients and usually occurs secondary to an inadvertent removal of parathyroid glands, mechanical or thermal injury or disruption of the vasculature. In some patients, it is observed that symptoms of hypocalcemia can occur for the first time several years after the surgery, which is known as “delayed hypoparathyroidism.” We report three cases of delayed hypoparathyroidism from Sri Lanka, presenting several years after total thyroidectomy. Case Presentation. Case 1- a 60-year-old Sri Lankan woman who presented with symptomatic hypocalcemia for the first time, 30 years after total thyroidectomy for follicular thyroid carcinoma. Case 2- a 53-year-old Sri Lankan woman presenting with neuropsychiatric manifestations of hypocalcemia for the first time, 12 years after total thyroidectomy for papillary thyroid carcinoma. Case 3- a 49-year-old Sri Lankan woman developing symptoms of hypocalcemia for the first time, 11 years after completion of thyroidectomy for papillary thyroid carcinoma. All these patients were detected to have low parathyroid hormone levels, without an alternative etiology for hypoparathyroidism, hence leading to a diagnosis of delayed post-thyroidectomy hypoparathyroidism. Conclusion. Delayed hypoparathyroidism is a rare phenomenon, which is secondary to progressive atrophy of parathyroid glands and slowly progressive hypovascularization of parathyroids due to scar tissue retraction following thyroidectomy. The nonspecific nature of hypocalcemic symptoms and lack of continuous follow-up for a long time after thyroidectomy could contribute to a further delay in diagnosis. However, it is an important diagnosis to consider in any patient with a history of neck surgery presenting with hypocalcemia, irrespective of the time duration of surgery, as timely diagnosis and treatment can prevent long-term complications of hypocalcemia and improve the quality of life.

The earliest information on Sri Lankan echinoid species belonging to the Irregularia dates back to Alexander Agassiz (1872). However, the current knowledge of diversity and distribution of irregular echinoids from Sri Lanka (formerly Ceylon) remains sparse. In addition, there are no recent taxonomic studies or biodiversity surveys for irregular echinoids, and no illustrated field-guides or reference collections are available specifically for Sri Lanka. To address these gaps, left open for more than 100 years since the work of Clark (1915), this study was conducted as an island-wide systematic sampling survey. Over 200 echinoid specimens were collected from 24 localities in Sri Lankan coastal waters by snorkelling and SCUBA diving down to 33 m depth. The collected specimens were identified using existing keys and authenticated with specimens available at the Natural History Museum in Vienna, Austria. The present study records 22 irregular echinoid species belonging to 15 genera and nine families in four orders. Among the identified irregular echinoids, six species, Echinocyamus megapetalus H.L. Clark, 1914, Fibularia ovulum Lamarck, 1816, Fibulariella angulipora Mortensen, 1948, Echinodiscus cf. truncatus L. Agassiz, 1841, Peronella oblonga Mortensen, 1948 and Brissus cf. agassizii Döderlein, 1885, are new records for Sri Lanka. Four unidentified, possibly new species belonging to the genera Fibularia, Jacksonaster and Metalia are reported, but kept in open nomenclature until more material becomes available. At present, the diversity of irregular echinoids from Sri Lanka now stands at 37 species representing 11 families in four orders. A dichotomous key is presented for all Sri Lankan irregular echinoids.

This study analyzes the oral traditions of Sri Lanka Creole Portuguese as a syncretism of European, African, and Asian sources, evidenced in literary themes, linguistic practice, and cultural traditions. Resulting musical, dramatic, and textual practices play a central role in defining tradition and maintaining group identity in the creole communities. Both the co-existence and the interrelationship of oral texts establish traditions which contribute to a system of creole culture that spread throughout Asia. References are primarily to Sri Lankan and Indian materials collected by scholars in the late nineteenth century and during my field work in the 1970s and 1980s. Sri Lankan verses refer to the east coast Burghers of Bat-ticaloa and Trincomalee and to the Kaffirs of Puttalam. This study also presents for the first time a unique source for data and comparative analysis from the H. Nevill collection at the British Library, which is an extensive manuscript of Sri Lankan Creole texts from the 1870s or 1880s written in Dutch orthography and including material subsequently published by Schuchardt, Dalgado, and others. The theoretical focus concerns the translation of European, African, and Asian materials into a Eurasian discourse that displaces the originals, creating a new textual system of Portuguese Creole oral materials in Asia. The texts that give definition to creole culture have proved remarkably persistent, surviving in Sri Lanka from the seventeenth century to the present.
