description: 62. Cremastobombycia morogorene De Prins, new species
(Figs 19, 115, 280–282, 413)
Diagnosis. Wing pattern and coloration of hindlegs of C. morogorene resemble Cameraria hexalobina, but the male genitalia of these two species clearly differ. Specifically, they differ in the shape of valvae, vinculum, and sclerotization of anellus. Male genitalia with multisetose apex of tegumen and the bipartite vinculum consisting of two lateral long branches, separate C. morogorene from the rest of Afrotropical Lithocolletinae.
Note: a similar biforked apically vinculum is found in Cameraria trizosterata Kumata, 1993 and C. barlowi Kumata, 1993 and in a less biforked degree in C. fasciata Kumata, 1993. All three latter species are distributed in Western Malaysia.

Description. Adult (Fig. 115). Forewing length: 2.25 mm.
Head: Vertex tufted with reddish-ochreous scales with a suffusion of a few white shorter scales posteriorly; frons smooth, shiny white with a slight bronze shading on fronto-clypeus near palpi. Maxillary palpus very small, slightly porrect, white. Labial palpus white, drooping, first palpomere with a few small, dark brown scales lateroventrally, terminal palpomere sharp caudally, directed downwards. Haustellum developed. Antenna slightly shorter than forewing, flagellum mainly fuscous with slightly ringed, narrow, light ochreous bands dorsally, each flagellomere with dark fuscous apical 3/4 and light ochreous base; ventrally flagellum ochreous; scape reddish ochreous posteriorly with infusion of pale ochreous shading anteriorly, 4–5 dark brown scales present on scape dorsally, scape with 6–8 light ochreous pecten, of different length; pedicel as rest of flagellomeres, only slightly larger.
Thorax: Reddish ochreous; tegulae uniformly reddish-ochreous. Forewing ground colour reddish ochreous; white/blackish fuscous markings consisting of two transverse fasciae, two costal strigulae, one dorsal strigula and marked blackish-fuscous area along termen; basal streak short, narrow white stripe slightly oblique towards apex with a couple of black scales; first fascia at 1/4, as a narrow, multiple curved, slightly oblique towards apex white band, richly edged apically with black scales as a narrow edging band from midline of forewing to costa, as a broad edging band, twice broader than white band, from dorsal margin to midline of forewing; second fascia at middle of forewing consisting of narrow white line parallel to first fascia but slightly broader, and richly edged with several rows of black scales apically; black edging of second fascia extending towards apex just above midline of forewing, uniting with rich black irroration at apical 1/4 of forewing; first costal strigula short, narrow, irregular stripe-shaped, apically edged with a spot of blackish scales, second costal strigula almost indispensable at apex, first dorsal strigula situated opposite first costal strigula, without regular shape, hardly visible, termen area richly covered with blackish scales; fringe line at tornus short ochreous fuscous with blackish-tipped scales, along dorsal margin pale fuscous. Hindwing greyish with long fuscous fringe, slightly darker shaded than hindwing. Fore femur and fore tibia dark fuscous, tarsomere I fuscous with a few white piliform scales basally, tarsomere II fuscous ventrally with white spot dorsally, tarsomeres III–IV dark fuscous, terminal tarsomere ochreous; mid-femur dirty white with dark fuscous patches basally and subapically, mid-tibia dirty white with large blackish fuscous patches basally, medially and apically, tibial spurs greyish with white apices without sharp transition borders, tarsomere I white with fuscous subapex, tarsomere II white with fuscous apex, tarsomere III blackish fuscous, tarsomeres IV white and tarsomere V pale fuscous; hind femur greyish, hind tibia grey with whitish ochreous apex, medial spurs fuscous with ochreous apices, apical spurs light ochreous with a couple of fuscous scales subapically, tarsomere I–II white with fuscous base and apex, tarsomere III with fuscous basal 2/3, white apically, tarsomeres IV white, tarsomere V greyish.
Abdomen: Dark fuscous dorsally. Genital segments ochreous brownish. Sternum VIII of male middle size broad, tapering with rounded apex.
Male genitalia (Figs 280–282). Tegumen long (ca. 760 µm), narrow, tapering towards tip bearing about 10 slender setae of median length and several microsetae. Valvae symmetrical, ca. 640 µm long, ventral margin almost straight with a light curve resulting to small dent in middee, dorsal margin slightly concave and cucullus area significantly dilated, somewhat trapezoidal with rounded dorso-apical angle, followed by almost straight apical margin and slightly projected lateroventally half rounded ventroapical angle; half oval seal following subapical margin of valva in cucullus area; dorsal margin of cucullus is covered with short stiff, setae; ventral margin of valva is setae free except small rounded setose island on small bult postmedially; about 9 long slender, setae randomly distributed on ventral surface of basal part of valva. Vinculum strongly sclerotized, widened laterally, biforked apically, each branch long, slender and somewhat knobbed apically; caudolateral part of vinculum tightly confluent to base of sacculus, basolateralparts of vinculum weakly joint by narrow junction; saccus very narrow, without apical projection, medianpart separated from vinculum; transtilla very narrow, weakly sclerotized, hardly touching caudolateral parts of vinculum. Aedoeagus ca. 915 µm long, narrow, tubular, slender, slightly down curved, tapering towards vesica, coecum anteriorly enlarged, bulbous, vesica narrow, with two long (ca. 222 µm), very slender, confluent cornuti forked at apex of vesica.
