“…Aside from their value in distinguishing species, the character states of pupae may be useful in cladistic analyses of these taxa. Recent studies have produced very thorough pupal descriptions of Culicoides pupae and have provided a template for future descriptions (Nevill et al 2009;Ronderos et al 2013;Anjos-Santos et al 2014;Shults et al 2016;Harsha et al 2017).…”

There are 160 valid species of Culicoides Latreille described from the Nearctic Region, but many are unknown as immatures or, although partially described, cannot be readily identified. We provide pupal diagnoses, descriptions, and a key to all seven known species of Culicoides subgenus Monoculicoides Khalaf occurring in the Nearctic biogeographic region. A diagnosis of several characters unique to this subgenus is provided to allow for the recognition of the included species from those of other subgeneric groupings. Microphotography of important morphological characters for both the key and descriptions are provided. This study highlights the usefulness of examining the pupae of Culicoides as a tool for species identification. The pupae of Culicoides grandensis Grogan & Phillips, C. occidentalis Wirth & Jones, and C. shemanchuki Grogan & Lysyk are newly described and those of C. riethi Kieffer, C. stigma (Meigen), and C. variipennis Wirth & Jones are redescribed in detail. The seventh species, C. sonorensis, was fully described recently.

“…Subsequently, immature specimens procured from the natural habitat were also examined. The morphology and terminology follow Day et al (1997) for eggs, Murphree and Mullen (1991) and Anjos-Santos et al (2014) for larvae, and Borkent (2014) for pupae. The morphological measurements of immature specimens are in µm, except the total length of larvae and pupae, which is expressed in mm.…”

Mellor et al., 2009). This species, first described by Kieffer (1910) from Puri, has since been reported in various parts of India (Prasad et al., 2009). The pupa was described by Mayer (1934) from Sumatra, whereas the egg, larva, and pupa were reported by Narladkar et al. (1991) without detailed taxonomy and illustrations based on recent terminologies. Based on adult morphology, Nandi (2014) revised the genus and recognized 11 species under the subgenus Hoffmania, including C. peregrinus. Light trap data revealing a high prevalence of this species in proximity to cattle (unpublished data) prompted us to describe all immature stages with modern terminologies based on scanning electron microscopy (SEM). This taxonomic information about the immature stages will help to precisely determine the oviposition sites, to specify larval habitats and the differentiation of larval instars, and ultimately to adopt effective control strategies against this vector species. This paper describes the ultrastructure of the egg and larval instars and offers a redescription of the pupa. Immature specimens of this species are presently recognized by the random arrangement of tubercles in two broad dorsoventral longitudinal rows of egg chorion, epipharynx combs 2 and 3 absent in larvae, and weak sclerotized band on the antennal sheath and presence of palpus tubercle in pupae. Materials and methodsWild adult females of Culicoides peregrinus were collected by operating a downdraft UV light trap (Harsha and Mazumdar, 2015a) within a cattle shed at Adisaptagram (22°56′50″N, 88°23′08.3″E), Hooghly district, West Bengal, India. The live engorged females oviposited after 48 h onto a wet filter paper within a glass vial (6.5 × 2 cm). Thereafter, the embryonated eggs (confirmed by the presence of eye spots) were reared in two different rearing media. Some eggs were placed in petri dishes, with absorbent cotton provided as a substrate and mud broth + 2% yeast solution provided as food in an environmental test chamber at 26 °C (model CHM-10S; REMI Elektrotechnik Limited, Vasai, India), following Harsha and Mazumdar (2015b). Similarly, cattle manure (natural breeding habitat) was bought to the laboratory and a few larvae and pupae were hand-picked from the cattle manure and were subsequently treated for description, while the rest of the cattle manure was kept for the adult emergence. A few of the embryonated eggs were processed for SEM after Day et al. (1997); for differentiation of instars, 6-7 larvae were extracted every day from the rearing dishes and mounted on slides following Das Gupta and Wirth (1968). The different larval instars were differentiated based on measurements and several ratios of the head capsule. Eggs, larvae, and pupae were also studied under a scanning electron microscope (model S5 30; Hitachi, Tokyo, Japan) at the Science Instrumentation Centre at the University of Burdwan. Similarly, larvae and pupae were Abstract: Detailed descriptions of the immature stages, i.e. eggs, larvae, and pupae, of Culicoides peregrinus Kieff...
