[email protected] Abstract: Lahugada dohertyi is one of the many lesser-known cicadas of northeastern India which has never been studied since its discovery. Recently, a century later, a populaton of this elusive cicada was discovered in northern West Bengal. This paper gives an account on its distributon in northern West Bengal, taxonomy, and natural history and suggests a common name based on its call and habitat preferences.

Lahugada dohertyi is a rusty red-coloured cicada Imaging: Panasonic Lumix DMC FZ-35 and Canon that was described by William Lucas Distant in 1891 EOS-600D Rebel T3i DSLR with Sigma 70–300 mm APO- from a single male specimen (Image 1) collected by Digimacro lens were used to photograph the cicadas in the American entomologist William Doherty from the feld. Canon EOS-1200D DSLR with Canon 50mm Margherita of Upper Assam (Fig. 1; Distant 1891, 1905). macro lens was used to photograph the specimen in the It was initally described as Pomponia dohertyi Distant, collecton depository of Natonal Centre of Biological 1891 (Distant 1891; Sanborn 2014; Price et al. 2016) Sciences (NCBS).

Unlike the members of Pomponia Stål, taxonomic work.

For Dissecton: The last two abdominal segments of the more than a century, nothing was known about its male specimen (NCBS-PZ562) were treated using 10% range, distributon, habitat preferences, or actvity KOH to dissect the genitalia, which was then preserved period. Recently, in 2014, I found the species in and in 0.5ml vials containing anhydrous glycerol. around Coochbehar Town, situated in northern West Morpho-taxonomy: The terminology used for the Bengal State of India, which gave me an opportunity to descripton of the adult cicada and the larval exuviae observe and study this cicada closely. This newly found was adopted from Moulds (2005) and Hou et al. (2014), point locaton report was mentoned in the recently respectvely. published annotated provisional catalogue of cicadas of Measurement: Morphometric measurements of the the Oriental region (Price et al. 2016). The catalogue, adult cicadas were taken from images using ImageJ (64- however, does not give any account on its distributon, bit Java 1.6.0) sofware. The measurement of the larval biology, or natural history. This paper gives a brief exuviae is not produced in this paper as the exuviae tend descripton of the taxonomy, larval morphology, and to shrink while drying, right afer the eclosion, distortng natural history of this lesser-known cicada along with a the actual measurement of the living last instar larvae. note on the distributon of this species in other parts of Locaton: The species was frst found opportunistcally northern West Bengal. in Chakchaka, a suburb of Coochbehar, in May 2014. A few days later it was found in Rasamat Reserve Forest. An atempt was made to conduct more focused actve MATERIAL AND METHODS searches for three weeks (22 April–13 May 2014) to check parts of Alipur, Jalpaiguri, and Coochbehar districts Specimen collecton: Most of the cicadas in the feld of northern West Bengal in order to understand the were spoted by their calls. Individual cicadas were distributon patern of this cicada. The same localites observed through Canon EOS-600D Rebel T3i Digital SLR were again checked briefy in May 2015. In 2016, all the with Sigma 70–300 mm APO-Digimacro lens and the localites were monitored from April to May in order to observed behaviour was noted down. Though an atempt record its actvity period. All the localites of this cicada was made to take the counts of the individuals, due to found in northern West Bengal are given in Table 1 and a lack of uniform and adequate sampling technique, it shown in Fig. 1. The GPS locatons of its precise localites is not included in the paper. Afer collecton, two legs were acquired but only degree and minutes are produced and part of the thoracic tssues were extracted in order in the paper due to conservaton issues. This cicada was to preserve the DNA for future molecular work. Each not found in the northern part of Alipur District towards insect was fxed with a pin through the mesonotum with Jayant of Buxa Tiger Reserve, the northwestern part of wings outstretched afer the extracton of the tssue. Jalpaiguri District such as Baikunthapur Reserve Forest, Afer fxing the insect, it was kept in a hot air oven for 48 Belacoba, Ambari, Odlabari, and Mal Bazar areas, and hours at 56C.
