Griphophanes magnus sp. nov.

( Figs. 9 A–B)

Material examined. SRI LANKA. HOLOTYPE 3: “ Ceylon, Sabaragamuwa, Prov. Maratenna, at 4500 ft, 7 mls N Balangoda, 22.II.62, Loc, 98”, “Swept in the veg. of small stream” ( ZMLU). PARATYPES: 2 3, same data as holotype (both ZMLU).

Diagnosis. Relatively large species; ac biseriate; first flagellomere as long as high; legs entirely dark brown, except trochanters yellowish brown; halter black; mid femur and tibia with av and pv row of long ventral setae which are longer than diameter of femur or tibia; crossvein dm-cu longer than apical section of CuA.

Description. Male: Length (holotype): body 2.3 mm, wing 2.5 mm. Head: Frons velvet black, with dense brownish pruinosity; eyes converging below antennae and almost contiguous; palpus black with a strong spine-like apical seta; antenna dark brown, first flagellomere about as long as high; lower postoculars black. Thorax: Mesonotum and scutellum dark metallic green, with brownish pruinosity; 5 strong dc, and 1 smaller anteriad; ac biseriate; scutellum with 2 strong marginal and 2 small lateral setae; pleura dark brown, with grayish pruinosity. Legs: Entirely dark brown, except trochanters yellowish brown. Fore leg: coxa with anterior setae; femur with multiseriate row of setae which are shorter than diameter of femur; tibia with ventral row of short erect hairs, and with strong and long ad seta at 1/3; basitarsus compressed laterally, with small spine-like ventral setulae; relative podomere ratios: 65, 60, 15/12/11 /10/8. Mid leg: coxa with several strong anterior setae; femur with strong anterior preapical seta, with av and pv rows of strong and long setae, partially distinctly longer than diameter of femur; tibia with av and pv rows of setae, longer than diameter of tibia, with strong ad setae at 1/3 and 2/3, strong pd setae at 1/ 4 and 1/2, and 3 strong apical setae; relative podomere ratios: 72, 80, 30/17/12 /10/8. Hind leg: coxa with 1 strong lateral seta; femur with strong anterior preapical seta, and 3–4 strong av setae on distal 1/4; tibia with strong ad/pd setal pair at 1/3 and 2/3, strong and long dorsoapical seta, and 2 strong apical setae; relative podomere ratios: 80, 87, 22/22/ 16/13/11. Wing: Hyaline, with grayish tinge; R4+5 slightly curved before wing margin, R4+5 and M parallel; CuAx ratio: 1.3; RMx ratio: 1.7; lower calypter pale brown with fan of dark brown setae; halter black. Abdomen: Dark metallic green, with brownish pruinosity; segments 6 and 7 ochreous brown, segment 8 dark brown; hypopygium dark brown, cercus yellowish brown. Hypopygium ( Figs. 9 A–B): hypandrium short and broad, subovate; epandrial lobe rectangular, with curved arm, bearing a strong apical and strong and long subapical seta; ventral lobe of surstylus triangular, with a strong subapical seta; dorsal lobe of surstylus subovate; with 3 small apical setulae, and with a strong dorsal seta; postgonite narrow, with small setulae; cercus elongate. Female: Unknown.

Etymology. The name refers to the relatively large body size of the species.
