The specific name mauritiana refers to the plant Ziziphus mauritiana Lam. from where the type specimens were collected. Remarks. Chant & McMurtry, 1994 recognised three species groups based on the presence or absence of setae J2 and R1: the horridus species group with setae J2 and R1 absent; the plumifer species group with setae J2 and R1 present and the purseglovei species group with setae J2 absent and R1 present. The present species Phytoseius mauritiana belonging to the horridus species group because of the absence of the setae J2 and R1 while the species Phytoseius kapuri Gupta, 1969 belongs to the plumifer species group. Phytoseius mauritiana is close to P. minutus (Narayanan, Kaur & Ghai, 1960), P. corniger (Wainstein, 1959), P. namkhanaensis Karmakar & Bhowmik, 2018 and P. roseus (Gupta, 1969) but the new species differs from P. minutus by its shorter j3 23, Z4 52 and Z5 60 than the latter species j3 67–71 Z4 76–83 and Z5 67–79. The new species differs from the latter species by the absence of J2 setae and shape and size of macrosetae of leg IV, and the spermatheca. The dorsal setae j3 23, s4 76 and Z4 52 of P. mauritiana are much shorter than the setae j3 48, s4 128 and Z4 84 of P. corniger. The new species differs from P. corniger by the shape of the ventrianal shield, which is sole-shaped in the former species and vase-shaped in the latter species. The macrosetae on leg IV of the new species are club-shaped in contrast with the rod-shaped macrosetae on leg IV in the latter species. The dorsal shield setae j3 23, s4 76 and Z4 52 of P. mauritiana are much shorter than j3 (31–40), s4 (99–100) and Z4 (72–78) of P. roseus. The genu, tibia and tarsus of leg IV of the former species have club-shaped macrosetae while in the latter species the genu lacks macrosetae. The new species also differs from the P. namkhanaensis by its concave posterior margin of sternal shield, shape of spermatheca, genital and ventrianal shield.Published as part of Bhowmik, Sagarika & Karmakar, Krishna, 2021, Five new species and re-description of eight species belonging to the family Phytoseiidae (Acari: Mesostigmata) from West Bengal, India, pp. 401-450 in Zootaxa 4975 (3) on pages 435-438, DOI: 10.11646/zootaxa.4975.3.1, http://zenodo.org/record/480780

In other parapodia (chaetigers 12 and 13), tubular cells invade into coelomic space (Fig. 4E–F).</p> Remarks <p> Following the redescription of <i>S</i>. <i>parva</i> by Moreira & Parapar (2002), it can be stated that <i>S. sundarbanensis</i> sp. nov. resembles <i>S. parva</i> Day, 1963. They have similar characteristics, such as median antenna longer than lateral ones, reaching chaetigers 3–4, and pharynx with 14 marginal papillae. However, they differ in several features, the most notable ones being the starting point of the dorsal hooks and the absence of capillary chaetae in the notopodia. In <i>S. sundarbanensis</i> sp. nov., the first appearance of dorsal hooks from chaetiger 8 remains constant in all 16 specimens, irrespective of specimen size. The hooks are accompanied by a single acicula, and the last two chaetigers are hookless. The notopodia are devoid of any capillary chaetae, neuropodia with 2–4 short pectinate chaetae with a variable number of spinulose or serrated capillaries, and the relative size of the median antenna is 2.3 times as long as the lateral ones. In comparison with <i>S. parva</i>, the median antenna is 1.5 times as long as the lateral ones, the notopodial hook starts from chaetigers 4–5 and is accompanied by single capillary chaetae in the posterior parapodial segments, neuropodia with 1–2 pectinate chaetae, but the number of hookless chaetigers is not mentioned in the literature (Day 1963; Moreira & Parapar 2002).</p> Distribution <p> <i>Sigambra sundarbanensis</i> sp. nov. is only known from the rivers Matla and Thakuran of the Indian Sundarbans.</p> Ecology <p>All specimens of this new species were found in mangrove habitats with silty sand sediments, in depths of 11 to 26 m. Mature specimens, with developed oocytes, were recorded in August and December 2019 from Thakuran River. Among all the abiotic factors, salinity plays a pivotal role in ecology and</p> <p> distribution of species across the globe, as this acts as a physiological barrier for both stenohaline and euryhaline species. <i>Sigambra parva</i> was recorded from Cape Province, South Africa (Day 1963) and the Mediterranean coast of Spain (Moreira & Parapar 2002), where the water salinity remains higher than30%, whereas the localities of <i>S. sundarbanensis</i> sp. nov. had a salinity of 17–23.42%. Additionally, <i>S. parva</i> had a comparatively higher range of depth variation from 2 to 97 meters (Day 1963; Moreira & Parapar 2002).</p>Published as part of <i>Bhowmik, Moumita, Ghoshal, Priya, Salazar-Vallejo, Sergio I. & Mandal, Sumit, 2021, Sigambra sundarbanensis sp. nov.

Parameter Estimation in Semi-Linear Models Using a Maximal Invariant Likelihood Function
No full textIn this paper, we consider the problem of estimation of semi-linear regression models. Using invariance arguments, Bhowmik and King (2001) have derived the probability density functions of the maximal invariant statistic for the nonlinear component of these models. Using these density functions as likelihood functions allows us to estimate these models in a two-step process. First the nonlinear component parameters are estimated by maximising the maximal invariant likelihood function. Then the nonlinear component, with the parameter values replaced by estimates, is treated as a regressor and ordinary least squares is used to estimate the remaining parameters. We report the results of a simulation study conducted to compare the accuracy of this approach with full maximum likelihood estimation. We find maximising the maximal invariant likelihood function typically results in less biased and lower variance estimates than those from full maximum likelihood.Maximum likelihood estimation, nonlinear modelling, simulation experiment, two-step estimation.
Predicting Vulnerability for Requirements
No full textSoftware security being one of the primary concerns in the software engineering community, researchers are coming up with many preemptive approaches aiming to minimize the vulnerabilities in the software. These approaches, dominated by static and dynamic analysis of the code often with machine learning (ML) techniques, are designed to detect vulnerabilities in the post-implementation stage of the software development life-cycle (SDLC). While they are found to be effective in detecting vulnerabilities, the consequences are often expensive. Accommodating changes after detecting a vulnerability in the system in later stages of the SDLC is very costly, sometimes even infeasible as it may involve changes in design or architecture. Moreover, the root of a vulnerability can often be traced back to the requirements specification. On that account, Imtiaz and Bhowmik have advocated a novel framework to provide an additional measure of predicting vulnerabilities at earlier stages of the SDLC. In this study, we build upon their proposed framework and leverage state-of-the-art ML algorithms to predict vulnerabilities for new requirements. We also present a case study on a large open-source-software (OSS) system, Firefox, evaluating the effectiveness of the extended prediction module. The results demonstrate that the framework could be a viable complement to the traditional yulnerability-fighting approaches

Etymology. The specific name astrictus refers to the unique character of spermatheca where calyx is constricted in this new species. Remarks. E. astrictus is close to E. victoriensis (Womersely, 1954), E. neovictoriensis (Schicha, 1979) and E. unisetus Moraes & McMurtry, 1983 but the former species differs from the latter species in the dorsal shield striation pattern, length of shield setae and shape of spermatheca. In case of the former species the dorsal shield setae S5, Z4, Z5 are longer than all the latter closely related species. The dorsal shield of the former species is strongly reticulated with lateral parallel lines which differs from E. victoriensis and E. neovictoriensis by their smooth and lightly reticulated dorsal shield respectively while in case of E. unisetus the dorsal shield imbricated and without lateral parallel lines. Euseius astrictus is also distinguished from other species of Euseius by its distinct constricted spermatheca.Published as part of Karmakar, Krishna & Bhowmik, Sagarika, 2018, Description of eight new species and re-description of four species belonging to the family Phytoseidae (Acari: Mesostigmata) from West Bengal, India, pp. 41-77 in Zootaxa 4422 (1) on pages 58-60, DOI: 10.11646/zootaxa.4422.1.3, http://zenodo.org/record/125102

Type Specimens. Holotype: female (Acar.lab/ BCKV /8268/2017) (Registration number 4414/17 deposited in the NZC, Zoological Survey of India, Kolkata), collected from Indian Heliotrope, Heliotropium indicum (Boraginaceae) at Kakdwip: 21° 87' 60" N, 88° 18' 53" E, 3 m above mean sea level, South 24 Parganas, West Bengal, on 8 April 2017, 9 paratype females (Acar.lab/ BCKV /8268-8272/2017), with same collection data as holotype. Etymology. The specific name heliotropium refers to the host plant, Heliotropium indicum L. from which the type specimens were collected. Remarks. Typhlodromus (Anthoseius) heliotropium is close to T. (A.) kutabus Schicha & Corpuz-Raros, 1992, T. (A.) charactus (Ueckermann, 1996) and T. (A.) eremicus Meyer & Ueckermann, 1989. The former species differs from the latter species by the posterior margins of the sternal shield, and the shape of the genital shield, ventrianal shield and spermatheca. The posterior margin of the sternal shield in the former species is bi-lobed while it is concave and wavy in T. (A.) kutabus. The dorsal opisthosomal region of the latter species is reticulated, but smooth in the former species. In the former species the calyx is funnel-shaped and constricted while it is bell-shaped and without constriction in the latter species. The peritreme of the former species extended to base of j3 while it is extended beyond j 3 in the latter species. The former species also differs from the latter species by the shape of genital shield, number of teeth in the fixed digit of chelicerae and reticulation pattern of ventrianal shield. Typhlodromus (Anthoseius) heliotropium differs from T. (A.) charactus by the shape of the sternal shield, reticulation pattern of the ventrianal shield, shape of spermatheca and length of the peritreme. The posterior margin of the sternal shield in the former species is bi-lobed while in the latter species it has a posterior medial lobe. The anal region of the ventrianal shield in the former species reticulated while it is smooth in the latter species, and the calyx of the spermatheca of the former species is short and funnel-shaped with a constriction at the end of the atrium, which is not found in the latter species. The peritreme extends to j 3 in the former species while it extends to base of j 1 in the latter species. Typhlodromus (Anthoseius) heliotropium differs from T. (A.) eremicus by the convex posterior margin of sternal shield, dorsal opisthosomal reticulation pattern, shape of ventrianal shield and shape of the spermatheca. The peritreme extends to level of z 2 in latter species while it extends to the level of j 3 in the former species.Published as part of Karmakar, Krishna & Bhowmik, Sagarika, 2018, Description of eight new species and re-description of four species belonging to the family Phytoseidae (Acari: Mesostigmata) from West Bengal, India, pp. 41-77 in Zootaxa 4422 (1) on page 67, DOI: 10.11646/zootaxa.4422.1.3, http://zenodo.org/record/125102

Two paratype females (Acar.lab/ BCKV /8655–8656/2019) from same host plant and same locality as holotype, 18 June 2019. Holotype female and one paratype female (Acar.lab/ BCKV /8655/2019) have been deposited in the National Zoological Collection (NZC), Zoological Survey of India, Kolkata with same collection data as above.</p> <p> <b>Distribution.</b> Asia: India, West Bengal, Bankura.</p> <p> <b>Etymology.</b> The specific name <i>jhilmiliensis</i> refers to the locality from where the holotype of this species was collected.</p> <p> <b>Remarks.</b> <i>Typhlodromips jhilmiliensis</i> is close to <i>T</i>. <i>syzygii</i> (Gupta, 1975), and <i>T</i>. <i>potentilae</i> (Garman, 1958) but differs from it by the shape of the ventrianal shield, the posterior margin of the sternal shield and the shape and dentition of cheliceral digits. The posterior margin of the sternal shield of the former species is strongly wavy while it is smoothly concave in the latter species also the ventrianal shield with a deep notch at the anterior lateral sides of the former species which does not match the shape of the pentagonal ventrianal shield of the latter species. The cheliceral fixed digit of the former species has six teeth and the moveable digit with two small teeth, while the latter species has more than ten teeth on the fixed digit and three teeth on the movable digit.</p>Published as part of <i>Bhowmik, Sagarika & Karmakar, Krishna, 2021, Five new species and re-description of eight species belonging to the family Phytoseiidae (Acari: Mesostigmata) from West Bengal, India, pp. 401-450 in Zootaxa 4975 (3)</i> on pages 427-429, DOI: 10.11646/zootaxa.4975.3.1, <a href="http://zenodo.org/record/4807806">http://zenodo.org/record/4807806</a>
