Fig. 371–374  
 This species is unique in the Cheumatopsyche mahakaya species group, easily separated by the absence of fork 1 in the hind wings; and in the genitalia by the presence of well-developed, dorsad curving, apicoventral setose lobes; and the shortened and stout harpagones.   
Male. Body and wings brown, with brown pubescence. Maxilary palp formula I-(III, IV)-II-V, segment V as long as sum of segments I–IV. Head dorsum brown, with brown setal warts. Swollen setal wart absent on proepisternum. Pretarsal claws apparently symmetrical, without laterally flanked setal bundle. Protibiae with 2 apical spurs, posteroapical spur small.  
Wings. Forewing Cu2 and A1 separate before costa. Wing membranes unicoloured brown without pattern. Forewing length 6.0 mm.  
Male genitalia. Abdominal segment IX fused annularly; tergum shorter than sternum (Fig. 371); anterior margins of segment IX almost regularly bow-shaped, with middle section straight and more strongly drawn, with posteriorly shifting dorsal section in lateral aspect (Fig. 371). Apical lobe on posterolateral margins nearly triangular, located above wide articulation cavity of gonocoxites. Spine row on posterior margins of segment IX almost complete; not intermittent, except short space below dorsal margin (Fig. 371); spines heterogenous, 3 times longer on laterocaudal protuberances of dorsum; short, stiff, straight on apical lobes. Intersegmental step between segments IX and X filled, occupied by pair of setose protuberances; forming setose laterocaudal lobes. Body of segment X long, nearly triangular, with highly dorsad curving, blunt, apex in lateral aspect (Fig. 371); simple, bilobed in dorsal aspect (Fig. 372); ventrum slightly bellied. Upturning apicoventral lobes fusing with segment X; dominating distal part of segment X; delineated by setae; rounded in lateral view (Fig. 371); apex turning anterad in dorsal view (Fig. 372). Smooth, mesal lobes reduced; dorsal interlobular gap narrow, triangular, deep (Fig. 372). Apex of fused apicoventral setal lobes separated by dorsal, interlobular gap with shape dependent on observation angle. Setose element present on basal, dorsolateral area of segment X; forming pair of well-developed protuberances, representing laterocaudal lobes. Transverse sutures short. Longitudinal sutures running along bottom of segment; forming continuation of apicoventral setose lobes. Setose areas (superior or preanal appendages) forming pair of elevated, circular flap-like warts located centrally on segment. Coxopodites exceeding apex of segment X, very slender immediately after basis, abruptly broadening to slightly posterad curvingdistal part before mid-length (Fig. 371); widening distad in ventral view (Fig. 373). Harpagones sharply triangular in lateral view (Fig. 371); curving slightly mesad in ventral view (Fig. 373). Phallothecal phallobase enlarged (Fig. 374); straight horizontal shaft tapering apically; slightly constricting before apex; with ventral broadening. Endophallus broadening at basis; ending in short tube at gonopore. Chitinesed endothecal process larg and circular. Phallotremmal sclerites vertically broad in lateral aspect.  
 Holotype male: MADAGASCAR: Fianarantsoa Province, 7 km W Ranomafana, 1100 m, black light, mountain rainforest, 22–31.x.1988 [W.E. Steiner] - (NMNH, pinned).   
 Distribution. Madagascar.   
 Etymology. ranoma, name derived from the type locality, Ranomafana.
