present species it is less curved and bears distinct small lamella (?second extension). Upper pygofer appendage elongated, bifurcated apically (Fig. 265). Arboridia soror Dwor. 1 M, Sikkim, Singtam, 30. X. 1981. C. A. Viraktamath. Arbosiria gen. n. Type-species: Arbosiria gracilis sp. n. Vertex produced and rounded anteriorly. Head narrower than maximum width of pronotum, coronal suture obscure (Fig. 286). Face short, almost flat, transition vertex to face broadly rounded, lorae moderately large, anteclypeus of a common form. Lateral frontal sutures distinct only in their ventral half, terminating near border of vertex. Wings form and venation (Figs 280, 281 ) as in Arboridia Zachv. In male genitalia dorsal bridge of pygofer extremely narrow, without tergite. Genital capsule almost spherous (Fig. 277). Anal tube not extending beyond hind margin of pygofer; subgenital plates exceeding pygofer. Segment 10 desclerotized in its distal half, the proximal half bears long appendage in its caudo-ventral part while the extension articulating with upper pygofer process arises in its cephalo-ventral part (Fig. 279). Lateral ligament knob-like, heavily sclerotized (Figs 277, 279, 292). Pygofer lobe sclerotized, well sculptured, ventral border of tergal part marked by an indistinct arcuate ledge; setosity consists of scarce small feeble microsetae at cephalo-ventral angle and on disk and an oblique row of small rigid microsetae on mesal side of the lobe (Fig. 279); some sensory pits in caudal part of disk. Upper pygofer appendage (Fig. 278) arising distinctly ventrad of dorsal margin of pygofer (Fig. 279). Cephalic part of paramere shorter than its central part, the caudal part lamellately broadened at apex (Figs 282, 287). Male basal abdominal apodemes distinct. The 1st pair small, semicircular, the 2nd pair lamellate, expanded mesally, and the small 3rd pair on 4th sternite (Fig. 293). Comparison. The new genus resembles Arboridia Zachv. by its external appearance, bi-armate connective (Fig. 290) and structure of subgenital plate (Fig. 285). However, pygofer structure and its setosity (especially lacking of the rigid microsetae on upper part of the membrane as in Fig. 265) is considerably different. Similarity to Frutioidia Zachv. is also superficial and can be found in subgenital plate structure. Penis resembles Arboridia, Frutioidia as well as some other genera. The most characteristic of the new genus is dorsal articulation of penis, structure of pygofer and anal tube and basal abdominal apodemes. Arbosiria gracilis sp. n. (Figs 277-293) Type material. - Holotype male: W Sikkim, Pelling, 2000 m, shrubs, 11. III. 1991,1. Dworakowska (in SMTD).
