( Figs. 6–10 ) Material examined. Holotype ; male, India : Sikkim ; Phusary lake , 2400 m , 27°14’35.7”N 88°46’52.7”E , 29-iv- 2009 , Pandher & Parey , ( NPC ). Paratypes . 2 males , 1 female , collection data same as for holotype . Diagnosis. This species is quite similar to Hydromanicus luctuosus Ulmer 1905 as redescribed by Malicky 2009 from India ( Assam , Himachal Pradesh , Meghalaya , West Bengal ), Bhutan , China , Nepal , Thailand , Laos , and Vietnam (also illustrated by Oláh & Johanson 2008 as Hy. truncatus Betten 1909 ) and Hy. serubabel Malicky and Chantramongkol 1993 reported from Thailand . It is closer to Hy. serubabel in general appearance of male genitalia. However, in Hy. betteni sp. nov. the preanal appendages are very long, almost reaching the apex of tergum X in dorsal and lateral views and tergum X laterally has rounded protuberances near its base in dorsal view; in Hy . serubabel , the preanal appendages are short, just reaching the triangular lateral protuberances in dorsal view and tergum X laterally has triangular protuberances near its apex in dorsal view. Moreover, the apical segment of each inferior appendage is pointed in Hy. betteni sp. nov. whereas, it is hooked in Hy. serubabel . Description, adult male . Color in alcohol brown, dorsum of head dark brown, legs and maxillary palps light brown, wings pale brown. Length from tip of head to apices of folded forewings about 12 mm ; maxillary palps each 2.25 mm long. Forewings each 10.50 mm long; crossveins m-cu and cu far apart; Sc and R veins ending independently on wing margin, Cu 2 and A separate to wing margin. Hind wings each about 7 mm long; fork I present; Sc and R meeting at cross-vein s before wing margin; stem of M and Cu 1 separate; median cell open. Male genitalia ( Figs. 6–10 ). Abdominal segment IX in lateral view convex anterolaterally, longitudinally long, apical lobe on posterolateral margin broad, rounded, setose, its posterior spine row continuous, anterior apodeme dividing segment IX into broad sternum and small dorsal tergum; in dorsal view anterior margin broadly concave, posteromedian keel broad, apically triangular, open distally, with pair of apicolateral lobes. Preanal appendages forming pair of long processes, each arising on elevated base, narrow basally, broadest at midpoint, covered by setae, apically pointed. Depression between segment IX and tergum X slightly indicated. Tergum X long, narrow, with rounded subapicoventral lobes and pointed apex in lateral view; in dorsal view quadrate with pair of rounded basolateral protuberances, its apicoventral setose lobes digitiform, long, quadrate apically, dorsal interlobular gap deep, narrow, demarcated by apicoventral setose lobes laterally, apicodorsal setose lobes reduced to pair of small setose longitudinal areas between basolateral protuberances. Inferior appendages each two-segmented; basal segment (coxopodite) long, slender, apically broadened in lateral view; in ventral view curved mesad; apical segment (harpago) small, broad basally, tapering and hooked at apex in lateral and ventral views. Phallic apparatus with anterior opening (phallic foramen) ventral, anterior part of phallotheca horizontal and very broad, narrowing before subapical ventral keel; phallotheca ending distally in circular sclerous endothecal process; median rim thickened, incurving, with pair of small irregular phallotremal sclerites located mesally and pre-apically; endophallus ending anteriorly in narrow tube with gonopore; broadly rounded, half ovoid subapicoventral keel of phallotheca visible in lateral view. Distribution. India : Sikkim . Etymology. This species is named after C. Betten, who described many species from India in this genus.
