Abstract Purpose The study aims to explore the argument of implementing the lean method to part or whole of an operation by examining the moderating impact of varying levels of the extent of implementation of four different lean methods, along with their functionalities, in predicting productivity improvement (PI). Design/methodology/approach As the focus of understanding the efficacy of lean principles is shifting from process to industry level, this study tried to generalize the approach by gathering data from 132 large Indian auto component manufacturers. This involves an assessing/monitoring approach rather than measurement. Findings Results highlighted the interdependence or individuality of the extent of implementation of lean methods and their functionalities. Findings revealed a significant moderating effect in improving productivity to a greater extent of 50%. Research limitations/implications Adopting an assessment approach to a measurement study provides a noteworthy contribution to bridging theory and practical consequences. The findings can be appropriately extrapolated to medium and small enterprises forming a critical connection in the entire automobile manufacturing ecosystem. Practical implications The study showed that even if a lean method is applied to a certain extent of operations the chances of PI are significant. This is important for decision makers as they confront problems of optimum resource allocation. Social implications PI, reduced cost and generalization of results would enable the auto component industry to become more competitive. Originality/value The examination of the moderation effect of a lean principle implementation extent, along with that of its functionalities to predict the improvement in productivity from its existing level, is a major outcome of this study.

Abstract The Hedge Cupid butterfly, Bothrinia chennellii (de Nicéville, 1884) (Lepidoptera: Lycaenidae) is rediscovered to Meghalaya, India, from two different localities since its last known records. The species was last recorded 63 years ago by Cantlie from Shillong, Khasi Hills, Meghalaya in 1952 and since then no records of this species has been found in the literature of the state. The species is legally protected under Schedule II of the Indian Wildlife (Protection) Act, 1972. In this paper taxonomy, distribution and current habitat of the species are discussed.

Resumen La mariposa Bothrinia chennellii (de Nicéville, 1884) (Lepidoptera: Lycaenidae) es redescubierta en Meghalaya, India, de dos localidades diferentes a partir de los últimos registros conocidos. La especie fue reportada por última vez hace 63 años en Cantile de Khasi Hills, Meghalaya, y desde entonces no se habían encontrado nuevos registros de esta especie en la literatura del estado. La especie está protegida legalmente bajo el Anexo II de la Ley de Protección de la Vida Silvestre de la India de 1972. En esta nota se discute la taxonomía, distribución geográfica y el hábitat que actualmente ocupa la especie.

Abstract The farmland visitor Bath White, Pontia daplidice moorei is recorded for the first time in Meghalaya. The butterfly is documented in an opportunistic survey on 17.v.2015 along the Guwahati- Shillong road, near Shangbangla village at an elevation of 520 meters. This record will help in updating the status of butterfly fauna in Meghalaya, India.

Resumen El visitante de las tierras de cultivo, Pontia daplidice moorei, se registra por primera vez en Meghalaya. La mariposa fue observada el 17 de mayo de 2015 a lo largo de la carretera Guwahati- Shillong, cerca del pueblo de Shangbangla a una altitud de 520 metros. Este registro ayudará a actualizar el estado de la fauna de mariposas de Meghalaya, India.
