colour; coxa with a basal and a subapical annulus light and dark brown, respectively; femur with three wide annuli dark brown; greatest part of tibia ochraceous except a wide basal annulus whitish; tarsus ochraceous. Meso- and metathoraces laterally dark brown; fore wings whitish, translucent, veins and their borders darker. Mid and hind coxae dark brown, femora ochraceous with a brown subapical annulus, femoral-tibial articulation broadly whitish, tibiae ochraceous, apically slightly darkened, tarsi ochraceous. Abdomen with five conspicuous, broad, dark brown transverse annuli. Head, thorax, abdomen and legs with short, adpressed pubescence and numerous very long, erect, usually curved hairs. - Head as shown in Fig. 4, elongate, fusiform, about 1.55 times as long as wide across eyes. Anteocular part elongate, anteriorly declivent; postocular part shorter than anterior part, feebly globose. Vertex with deep transverse furrow between eyes. Eyes relatively small, prominent, globose, approaching ventral surface of head in lateral aspect. Diatone 1.7 times as wide as interocular space. Labial segment I cylindrical, atteining antenniferous tubercle, segment II apically narrowed, surpassing the middle of eye, segment III slender, passing the hind margin of head. An­tennae long and very slender, segment I slightly longer than segment II. - Pronotum as shown in Fig. 4, elongate, about 2.3 times longer than its greatest width (across humeral angles), sharply separated into fore and hind lobes by a transverse constriction; fore lobe slender, about 1.05 times longer than hind lobe, lateral margins straight, diverging anteriorly; hind lobe subtriangular, hind margin con­cave, humeral angles broadly rounded. - Fore leg gracile. Coxa long, cylindrical, about half as long as femur. Femur long, slender, about 28 times longer than its maximum width, with two rows of spiniferous tubercles; posteroventral series composed of 10 large and about 75-80 small spiniferous tubercles, anteroventral series of 11-12 large and about 80-85 small ones. Tibia about 0.8 times as long as femur, slender, slightly arched, its ventral surface with a single row of about 20-25 stout and about 55-60 somewhat smaller spines. Tarsus small, its segments subequal in length. Mid and hind legs extremely elongate and delicate. Fore wing without subbasal cell. - Abdomen elongated, slen­der. - Measurements (in mm). Total length of body (from apex of head to posterior end of abdomen) 17.5. Length of head 1.68, preocular part 0.77, postocular part 0.53; width across eyes 1.08, interocular distance 0.64. Length of antennái segments I : II = 10.05 : 9.80 (segments III—IV absent on holotype). Length of labial segments I : II : III = 0.91:0.76: 0.86. Length of pronotum 3.95, fore lobe 2.03, hind lobe 1.93; width across humeral angles 1.73. Length of fore coxa 3.75, femur 7.50, tibia 6.20, tarsus 0.71 ; length of mid femur 12.60, tibia 19.50, tarsus 0.29; length of hind femur 15.70, tibia 28.22, tarsus 0.63. Etymology-The name is from Latin incompta, 'unkempt', 'tousled', referring to the long and curved hairs of the species. Diagnosis - Myiophanes incompta sp. n. can be distinguished from the other known species of the subgenus by its characteristic colouration: apparent dark annulation on fore legs, fore pronotal lobe with a broad central annulus dark brown, hind pronotal lobe dark brown with a pair of longitudinal stramineous stripes anteriorly and abdomen with five dark brown transverse annuli. The new species bears similar colouration with M. greeni and M. zebrina sp. n., but it can be distinguished from these species by the shape of its pronotum, which is less elon­gate, and rather stout at the level of transverse constriction between the fore and hind lobes.
