description: Neadeloides nubilus N. Singh, Ranjan & H. Singh, sp. nov.
(Figs: 6, 7, 10, 11)
Type locality: Golitar (Sikkim, India).
Type material: Holotype, ♂, 23.iv.2014, NE India, Sikkim, Golitar, leg. H. Singh (Coll. NZCZSI). Paratype: 2 ♂, 5.ix.2016, India, West Bengal, Neora Valley National Park, Rishap, leg. K. Bhattacharyya (Coll. NZCZSI).
Diagnosis: Neadeloides nubilus, sp. nov. belongs to the N. nubilus species-group, whereas both previously known species of this genus, N. cinerealis and N. glaucoptera, belong to the N. cinerealis species-group. The differentiation of both groups has been stated earlier.
Description. Wing span: Male— 38 mm. Adults greyish brown. Head with lateral sides, underside of neck and first segment of labial palpi white, latter with first & second segment upturned, third segment porrect. Legs with tibia and tarsal segments covered in white scales. Forewing greyish brown, hindwing with costal and inner area slightly paler, both wings with fine, dark brown marginal line, cilia silvery. Male genitalia (Fig. 10) with uncus inverted u-shaped, strongly concave on posterior side, small subapical process at either side; tegumen broad, slightly bifurcated to hold similarly shaped base of uncus; small socii present; transtilla membranous. Valva broadening towards apex, costa concave with central and subapical portion outwardly angled, apical flap of saccular process and central flap on inner wall closely approximated; ventral margin slightly convex; sacculus process broad rectangular with a small, setose apical flap; another setosed flap at the centre of inner wall of valva and in closely proximity of the apical flap of the sacculus process. Juxta small, short, u-shaped with lateral, small triangles; saccus u-shaped; aedeagus short, slightly s-shaped with a bulbous coecum at the anterior end and two sclerotized posterior processes: one is robust, slightly S-shaped, with one edge dentate, and the other is simple elongated; vesica with field of scobination (cornuti in Neadeloides are deciduous in nature so they may be secondarily lost after copulation).
Etymology: The species epithet of the new species is derived from the Latin word nubilus, meaning dark.
Taxonomic note: We studied three specimens of N. nubilus, sp. nov. and found some variations: in holotype, forewing and valva of male genitalia are slightly broader than both the paratypes; in vesica of holotype, spines are absent. But as the cornuti in Neadeloides are deciduous in nature so they may be secondarily lost after copulation. In the present study, we are considering these variations as intraspecific. However, future surveys in the area will help in building more population of this group and can further clarify the taxonomic position of this population.
