3. Leptoconops (Holoconops) tenebrostigmatus View in CoL sp. n.
( Figs. 3a–g View FIGURES 3 a – g )
Type material. Holotype Ƥ, India, Jharkhand, Maithon Fish Farm, 23 June 1998, Coll: N.C. Saha. Paratypes 6 Ƥ, same data as holotype; 1Ƥ, West Bengal, Burdwan DVC substation area, N 23o 23’, E 87o 85’, 21 August 1994, Coll: P.K. Chaudhuri.
Etymology. The name, “ tenebrostigmatus ” derives from the dark brown stigma of the wing.
Diagnosis. The species is recognized by clypeus with 4 setae, more or less moniliform flagellomeres I-X, stout flagellomere XI with apical setae, palp segment III dark, distal part swollen with widely open broad truncate sensory pit, mandible with 11 short teeth, scutum with dark brown linear streaks and lateral setae, wing brown with dark brown stigma and subequal spermathecae with very small neck, each with 4 and 8 stray apical spots.
Description. Adult female. Dark brown. Head. Dark brown. Eyes bare, and separated as wide as 6 facets. Clypeus ( Fig.3 a View FIGURES 3 a – g ) with 2 median and 2 lateral setae.Antenna ( Fig.3b View FIGURES 3 a – g ) dark brown, flagellomeres I-X with a row of 4 long basal and 2 short apical setae, XI massive sub cylindrical with many large and a strong apical seta; AR 1.21. Maxillary palpus ( Fig. 3c View FIGURES 3 a – g ) brown, palpomere III dark brown, swollen distally, with widely open broad truncated sensory pit, palpomere IV+V brown, slightly shorter than PM III, bearing 4 apical setae; PR 2.4. Mandible ( Fig. 3d View FIGURES 3 a – g ) with 11 teeth.
Thorax. Dark brown to brown. Scutum dark brown, with dark linear marginal dark linear lateral streaks and stray anterolateral and caudolateral setae.
Wing ( Fig. 3e View FIGURES 3 a – g ). Wing length = 0.8, breadth = 0.32; CR = 0.41. Brown, with dark brown stigma and anterior veins, tip narrowed bearing coarse hairs and dark anterior veins, microtrichia covering the wing surface, radial cell obsolete.
Legs. Femora dark brown and tibiae and tarsi pale brown. Fore tarsomeres each with I basal, 1 middle, and 2 short apical setae, foretarsomere II with 1 apical seta; mid tarsomere I with 2 basal and 1 apical setae, midtarsomere II with 1 apical seta; hind tarsomere I with 1 basal and apical setae; hindtarsomere II with 1 apical seta. Hind tibial comb ( Fig. 1f View FIGURES 1 a – h ) with 2 long and 2 short setae. TR of hind leg 1.42. Claws small, equal.
Abdomen. Tergites light brown. Spermathecae ( Fig. 3g View FIGURES 3 a – g ) subequal, oval, 0.046 x 0.027 and 0.042 x 0.027, with very small neck and each with 4 and 8 small, scattered, apical spots.
Discussion. The new species bears affinities with L. (H.) latibuloram Gutsevich and L. (H.) whitseli Clastrier & Wirth in the structure and chaetotaxy of the flagellomeres and with L. (H.) asilomar in color of the stigma. It also comes closer to L (H.) tuotuohea Liu & Gong (2003) and L. (H.) conulus Yu & Liu in the arrangement of setae on the clypeus and tarsomeres and with L. (H.) tibetensis in the spermathecae but possesses such differences as elongated maxillary palpus, 11 short teeth of mandible, dark brown linear streaks on scutum, wing brown with dark brown stigma, and spermathecae with stray apical spots. These differences compel us to favor establishment of a new species here.
