Sensilla chaetica: Mid Ta1 - 9,10; Hind Ta1 - 6,6.

Superior volsella beaked, of D-type, between d and e of Strenzke (1959).  Setae of Inferior volsella forked.
About 19 setae on tergite IX.

Pupa:  Not currently known

Fourth instar larva: a medium sized plumosus-type larva (female abt 12.2 mm).  Anterior ventral tubules shorter (abt 2.44 mm) than the posterior pair (abt 2.64 mm); lateral tubules well developed (abt 400 µm).
Gular slightly darkened, frontoclypeus dark, particularly at posterior of head.
Mentum with 4th laterals reduced almost to height of 5th laterals (type II), 6th laterals originating slightly below the level of other teeth;  teeth relatively sharp;  centre trifid tooth with c2 teeth well separated, tending to type IV.
Pecten epipharyngis with about 16 sharp teeth.  Ventromental plates separated by about 30% of the mentum width, with about 42-44 striae.
Premandible relatively broad and blunt, teeth about equal in length, inner tooth about 1.5-2 times the width of the outer tooth.
Antenna with a moderately long basal segment, which is about 4 times as long as wide; AR about 2.06; ring organ just under half way up from base.  Antennal proportions: 130 : 29 : 8 : 13 : 6.
Mandible with 3rd inner tooth well developed but only slightly darkened (type IIIB), about 14-15 striae on inner margin at base.

Cytology:    4 pairs of chromosomes with the pseudothummi arm combination AE, BF, CD, G.    Does not appear to be a nucleolus in arm G, but a large medial BR. Nucleolus in arm F probably at about group 19.    Polymorphism at least in arms D and G.
Arm A1:    1 - 2c, 10 - 12, 3, 14c - 13, 4 - 9, 2ed, 14d - 19                                      as "sam"A2
Arm B1:    Puff (group 7) about one third from distal end, with dark bands (group 8) distal to it.            possibly as cirB1
Arm C1:   
Arm D1:
Arm D2:    Small simple inversion near the middle of the arm
Arm E1:    1 - 2c, 5 - 10b, 3e - 2d, 4 - 3f, 10c - 13                                          as incertipenis, nr. samoensis
Arm F1:    possibly 1 - 2a, 10d-a, 15 - 11, ??, 19-23

Found:    India - Jammu & Kashmir: Bishnah wetlands; Deoli Village; Farooq Nagar; Gadhigargh; Sangrampur Village.

Molecular Data
The mtCO1 sequence is very similar to that of C. flaviplumus, and also close to that of C. nr. samoensis.
