No full textTeliphasa dodaki Ranjan, Singh & Kirti, sp. nov. (Figs 5, 6, 16) Diagnosis: Morphologically, T. dodaki Ranjan, Singh & Kirti, sp. nov. (Figs 5, 6) is very similar to T. orbiculifer, but is distinct in the forewing lacking a medial zigzag line, and in the pale fulvous hindwing with a fuscous postmedial line and the area beyond it concolorous except for the fuscous apex, whereas in T. orbiculifer the forewing exhibits a medial zigzag line, and the hindwing is pale yellowish–cinereous in male, with a slender, curved purplish–brown discal line and a broad marginal band (Moore 1888: 201). Further, T. dodaki sp. nov. is distinct from another similar species, T. nubilosa, by the yellowish forewing ground colour, and the hindwing with a prominent postmedial line, with the area beyond it with faint traces of fuscous suffusion, and a prominent fuscous marginal band present, whereas in T. nubilosa the forewing ground colour is dark greyish–green and the hindwing is almost uniformly fuscous, except the basal costal area, with the hindwing marginal band diffused with fuscous ground colour (Fig. 1). In the male genitalia of T. dodaki sp. nov. (Fig. 16), the valva is shorter the vinculum is approximately half the length in comparison to that of T. nubilosa (Fig. 15), and the aedeagus is cylindrical, while the distal half of the aedeagus is broader in T. nubilosa. Teliphasa dodaki sp. nov. is further distinct from the other two similar species T. amica and T. erythrina by the enlarged labial palpi reaching up and backwards to prothorax (whereas in both other species the labial palpi only reach up to the frons), the yellowish forewing ground colour and the hindwing with traces of postmedial line (whereas forewing ground colour is fuscous in the other two species except for the medial area of forewing and basal area of hindwing in T. amica (Liu et al. 2016: Fig. 12) and the forewing with rusty brown scales and an absent postmedial line in the hindwing of T. erythrina (Fig. 9)). Description: Adult with labial palpi upturned reaching up to prothorax. Antennae in male ciliated (female unknown). Forewing covered with olivaceous fulvous scales. Basal area fuscous. Postmedial line outwardly bent at middle, then obliquely running inward up to hind margin. A dark discal spot with white scales. Chequered fuscous spots from apex to tornus. Colour of ciliae alternating between fuscous and fulvous. Hindwing pale fulvous, faint traces of pale fulvous postmedial line; a fuscous patch at apex; outer margin with fuscous spot. Abdomen covered with alternating transverse bands of fuscous and white scales. Legs covered with fuscous scales accept tip on each joint. Male genitalia with uncus short; a sclerotised membrane running parallel to the tegumen and joined at tegumen-vinculum junction; tegumen ribbon-shaped; vinculum U-shaped, saccus reduced; juxta split into two separate arms; transtilla membranous; gnathos arms heavily sclerotised, reaching up, then arching medio-ventrad; valva rounded fan-like, costa straight to slightly concave; aedeagus elongate, slightly bent at middle, vesica with a small cornutus.

Teliphasa spinaejuxta Ranjan, Singh & Kirti 2022, sp. nov.
No full textTeliphasa spinaejuxta Ranjan, Singh & Kirti, sp. nov. (Figs 7, 8, 13, 19) Diagnosis: Teliphasa spinaejuxta sp. nov. is distinct from all other Teliphasa species by male genital with the apex of the large, plate-like juxta bearing two strong spines. Externally, T. spinaejuxta sp. nov. (Figs 7, 8) is similar to T. elegans (Liu et al. 2016: Fig. 11) and T. albifusa (Liu et al. 2016: Fig. 10), but is distinct from T. elegans by the fuscous forewing with whitish scales on medial area and a fuscous band in the basal area (whereas in T. elegans, the forewing is almost uniformly fuscous), and from T. albifusa by the medial whitish area of forewing densely tinged with fuscous, and by the presence of a bar-shaped discal spot (whereas in T. albifusa, the medial area of the forewing is whitish with two prominent fuscous spots (Liu et al. 2016: Fig. 10)). In male genitalia, T. spinaejuxta sp. nov. (Fig. 19) differs from T. elegans in the juxta with its two short, apical spike-like processes (juxta without processes in T. elegans). In comparison to the male genitalia of T. albifusa, the costa of the valva is narrower and almost straight in T. spinaejuxta sp. nov. whereas in T. albifusa, it is convex (Liu et al. 2016: Fig. 18). Description: Adult with labial palpi upturned. Thorax covered with fuscous scales. Forewing with basal area olivaceous, outlined with fuscous. Medial whitish area tinged with olive scales. Postmedial fuscous zigzag line running outwards to vein R 5, then inwards, running parallel to median venation, then obliquely running to centre of the hind margin. Postmedial area shiny fuscous. Hindwing postmedial area fuscous, paler towards base. Legs fuscous and banded with white scales. Abdomen banded with black and white. Male genitalia with uncus subovate, tegumen-vinculum complex forming an oval, saccus elongated; juxta broad, rectangular with a pair of apical spines; transtilla membranous; valva almost rounded, median (inner) surface densely covered with long setae; distal half of aedeagus strongly sclerotised. Female genitalia posterior and anterior apophyses of equal length; ductus bursae slightly bent; corpus bursae oval with a patch of cornuti towards tip. Material examined. Holotype ( ♂).

Ranjan leg. (Coll. NZCZSI). Diagnosis: Externally, L. whitakeri sp. nov. closely resembles L. mediobarbalis (Janse 1931: pl. 35, fig. 4; pl. 32, fig. 13) and L. obscura (Janse 1931: pl. 35, fig. 8; pl. 32, fig. 11), but is distinct by the basally bifurcated cornutus (L. mediobarbalis with a single-spined cornutus, and in L. obscura cornutus absent), the maxillary palpi and 2 nd segment of the labial palpi being well developed (both structures are less developed in L. mediobarbalis), the juxta bearing apically bifurcating asymmetric lateral processes, and by the valva lacking any structure on the outer margin; in L. obscura the juxta bears two long, non-bifurcating processes, and the valva bears a small curved hook initiating from sub middle of the outer margin. Another very similar species is L. moncusalis, from which L. whitakeri sp. nov. is distinct by the 2 nd segment of the labial palpi being hollowed out for over 2/3 rd of its upper length (it holds the scales of the maxillary palpi), while in L. moncusalis the 2 nd segment of labial palpi is hollowed out at the apical half only. Description: Adult fuscous brown. Labial palpi recurved, reaching prothorax; 2 nd segment extremely long, apical 2/3 rd hollowed out and holds a bunch of long scales forming a fan-like structure originating from the maxillary palpi; 3 rd segment small, curved, approximately 1/5 th of 2 nd segment. Forewing with an antemedial tuft of black scales below cell; another medial tuft in cell; 3 rd bar-shaped tuft on discocellular; indistinct sub-basal antemedial line; medial line oblique; postmedial line strongly excurved at median veins, obliquely incurved to meet inner margin; area beyond postmedial line paler; terminal series of dark spots, interrupted with veins; followed by a fine pale line; double series of long and short cilia. Hindwing with subcostal area paler from base to beyond middle; a terminal line pale; cilia with dark bases, apical 3/4 th paler. Male genitalia. Uncus bifid apically, lobes slightly oval, dorsal series of setae present on the apical and lateral edges of lobes, basal uncus widened into lateral arms and broadly attached to apical tegumen; tegumen approximately half the length of uncus; vinculum broad, slightly longer than tegumen; saccus reduced; juxta large, egg-shaped, with two large strongly sclerotised, apically bifurcating asymmetrical processes emerging from each side of the juxta base, left process shorter, thinner, apically bifid and right process longer, broader, broadened toward bifurcated apex, with the left arm of bifurcation curved and more than three times longer than the right arm of bifurcation; valva elongated, membranous, apically broadened, apex produced dorsally; harpe present; aedeagus with conspicuous coecum; vesica with a robust spine, bifurcated asymmetrically at the base. Distribution: So far, L. whitakeri sp. nov. is reported from Indian Himalaya (Sikkim and Uttarakhand). Etymology: The species is named in honour of Dr. Terry Whitaker, United Kingdom, an expert for global Pyraloidea especially the groups of Southeast Asia.Published as part of Ranjan, Rahul, Singh, Navneet & Kirti, Jagbir Singh, 2022, A new genus, three new species and a new species record of Epipaschiinae (Lepidoptera: Pyralidae) from India, pp. 385-394 in Zootaxa 5222 (4) on page 390, DOI: 10.11646/zootaxa.5222.4.7, http://zenodo.org/record/746680

Ranjan (Coll. NZCZSI). Paratypes: India, Karnataka: Ganeshgudi (14.9867°N, 74.5934°E), 387 m, 1 ♂, 28.xi.2013; Jog falls (14.22660 N, 74.805 80 E), 471 m, 1 ♂, 21.xi.2014, leg. R. Ranjan (Coll. NZCZSI). Diagnosis. Externally, T. ganeshgudiensis, sp. nov. (Fig. 1) closely resembles to T. subolivalis Snellen (Fig. 2), but it is distinct based on: (1) the forewing having the medial line absent and the postmedial line diffused, both the lines are prominent in T. subolivalis; (2) the forewing apex being dark chocolate coloured with a fuscous tip, in T. subolivalis the apex is of the same colour as the rest of the wing; and (3) the hindwing displaying a very faint postmedial line, with the area beyond it representing the marginal band, in T. subolivalis both the antemedial and medial lines are prominent, marginal band absent. The new species differs from the rest of its congeners in the pale brownish ground colour of the adults, which is black in T. rubriceps (Fig. 3) and T. nigraregina (Fig. 4), and redder in T. productalis (Fig. 5) and T. bilinealis (Fig. 6). In the male genitalia, T. ganeshgudiensis, sp. nov. (Figs. 7, 8) is similar to T. rubriceps (Figs 11–13), but is distinct in the vesica with its shorter cornutus and the absence of sclerotised plate, which in T. rubriceps, the cornutus is longer and a sclerotised plate is present. Description. Holotype male, forewing length 16 mm. Head with vertex pale brown; thorax and abdomen rusty red, the latter with anal tuft present at lateral sides. Patagia bearing prominent hairs. Forewing pale brown, densely speckled with rusty brown scales; a postmedial, semi-elliptical, paler spot on costa; a slightly sinuous, narrow, dark band (depicting the diffused postmedial line) from apex to postmedial region of inner margin. Hindwings pale brown, speckled with rusty brown scales; a very faint postmedial line, area beyond it dark and forming a marginal band. Fringe of both the wings fuscous. Male genitalia with uncus broad tongue shaped, decorated with small hairs; tegumen broad, shouldered; gnathos with hooked tip; valvae broad tongue shaped, costal margin slightly curved, fibula short with blunt tip; juxta with both the edges almost parallel; saccus bowl shaped; vesica with single cornutus. Remarks: The new species is placed in the genus Toccolosida due to presence of prominent hair on the patagia, uncus and valvae typically tongue shaped, the latter having a prominent fibula at base. Distribution. The new species is reported from Karnataka (southern India), which is an extended distributional range (in India) of Toccolosida from the Himalayan territory to the Western Ghats of India. The species was collected during post monsoon season in an elevational range between 350 m to 500 m. Etymology. The species is named after the type locality Ganeshgudi (Karnataka, southern India).Published as part of Singh, Navneet, Kirti, Jagbir Singh, Ranjan, Rahul & Chandra, Kailash, 2020, A new species of Toccolosida, a Pyralinae from the Western Ghats, India (Lepidoptera, Pyralidae) and the revised status of Lixa as a synonym, pp. 101-107 in Zootaxa 4816 (1) on page 102, DOI: 10.11646/zootaxa.4816.1.6, http://zenodo.org/record/395414
GPfit: A new R package for fitting Gaussian process models to deterministic simulators
No full textGaussian process (GP) models are commonly used for emulating computationally expensive computer simulators. Fitting a GP model requires the computation of the inverse and determinant of the spatial correlation matrix, R. The near-singularity of R can cause instability in the computation of its determinant and inverse. Ranjan et al. (2011) proposed a robust approach to overcome this problem. They used a robust but somewhat slow genetic algorithm based approach for maximizing the likelihood. In this thesis we investigate several parameterizations of the likelihood for ease of optimization. We then develop a new algorithm to nd the global optimum of the likelihood surface. Moreover, we developed an R package called GPfit that imple- ments the proposed methodology. Finally, we use several test functions to compare the performance of our approach with a popular GP tting package in R
A priori and a posteriori analysis of the hybrid two-level large-eddy simulation method for high Reynolds number complex flows
No full textWe present a priori and a posteriori analysis of the assumptions and predictions of the hybrid two-level large-eddy simulation (TLS-LES) method for high Reynolds number complex flows. The TLS-LES methodology is a multi-scale framework for simulation of turbulent flows in complex configurations at practically relevant Reynolds number. It additively combines the two-level simulation (TLS) model with a conventional large-eddy simulation (LES) approach by employing a static or dynamic blending function. In the present study, first we analyze the model assumptions employed by the TLS model to obtain the small-scale solution necessary for closure of the large-scale equations. Afterward, we analyze the large-scale and small-scale solutions to assess the predictive ability of the multi-scale framework for specific turbulence physics such as role of forward and backscatter of energy and presence of co- and counter-gradient diffusion. To perform these investigations, we consider cases with increasing degree of geometrical complexity, namely, flow in a periodic channel, flow past a bump placed on the lower surface of the channel and flow past a finite-span NACA0015 airfoil

Ranjan leg. (Coll. NZCZSI). Diagnosis: Externally, Atkinomus parilis sp. nov. most closely resembles Canipsa atkinsonii Moore, but it is distinct from the latter in the backwards bent basal process of the antennae and the forewing’s basal area being much darker (without any antemedial pale band), whereas in C. atkinsonii the antennal process is straight and crown-like (not directed backwards) and the forewing with a pale, slightly curved antemedial band. In the male genitalia, A. parilis sp. nov. is distinct from C. atkinsonii in the apically and basally broader uncus, the saw-like medial plate of the valva, and the juxta with the apico-lateral arms fused apically to form a ring, whereas in C. atkinsonii the Tshaped uncus is apically narrow and bearing two long lateral processes; the valva lacks any plate in the medial area, and the short apical processes of the juxta are free. Description: Adult. Head with labial palpi porrect, white, tinged with fulvous, 3 rd segment white dorsally, dark ventrally. Antennae minutely serrate, fasciculate; first segment of antennae with long, whitish, hairy process, suffused with fuscous. Forewing with basal area fuscous; medial upper half whitish; below subcostal nervure greenish fuscous; inner margin fulvous ochreous; postmedial crenulated line, straight from costa to vein M 1, then rounded and inwardly extends up to median nervure, then curved below Cu 2 and reaching inner margin; area beyond postmedial line pale fulvous, tinged with fuscous. Hindwing with postmedial line sinuous, diffused towards costa, area beyond it fuscous; margin of both wings outlined with black. Cilia of both wings banded with fuscous and white from apex to tornus. Thorax whitish tinged with fuscous. Abdomen black laterally, whitish dorsally and ventrally. Legs fuscous, banded with white. Male genitalia. Tegumen slightly longer than uncus; gnathos highly sclerotised with the small curved spine-like apical process; transtilla sclerotised basally, membranous apically; vinculum longer than tegumen, narrow, broad u-shaped; aedeagus elongate, bent medially; vesica without any cornutus. Female. Unknown Distribution: So far, A. parilis sp. nov. is only known from its type locality, i.e., Sikkim (India). Etymology: The Latin species epithet ‘parilis’ means ‘similar’, referring to its similar appearance with C. atkinsonii. Taxonomic note: The two similar-looking but different species i.e., Canipsa atkinsonii and Atkinomus parilis sp. nov., assigned to different genera is an excellent example of convergence. Furthermore, C. atkinsonii looks substantially different from Canipsa suspensalis Walker, the type species of Canipsa (holotype illustrated here: https://oumnh.ox.ac.uk/collections-online#/item/oum-catalogue-3032). We are quite sure that the study of genital morphology of C. suspensalis will lead to the resurrection of the genus Sarama Moore (with its type species C. atkinsonii) from the synonymy of Canipsa and the new genus, Atkinomus gen. nov. described here will prove to be the most closely similar to Sarama.Published as part of Ranjan, Rahul, Singh, Navneet & Kirti, Jagbir Singh, 2022, A new genus, three new species and a new species record of Epipaschiinae (Lepidoptera: Pyralidae) from India, pp. 385-394 in Zootaxa 5222 (4) on pages 386-388, DOI: 10.11646/zootaxa.5222.4.7, http://zenodo.org/record/746680
