(Fig. 14)
Type depository. Holotype male in OMNS, two paratype males and females in JWGC, one paratype male and female each in YAUM and DARM, five paratype males and nineteen paratype females in MHWJ.
Type status. Holotype male, type labels: “ Sa Yoe, near Thet keg yin, / Maharmyaine Wildlife Sanctuary, / Sagaing Region, Myanmar / May 31, 2016 / Michio HORI & Thanda Moe leg.”, “ HOLOTYPE / Cylindera (Ifasina) / thitarooae / Wiesner & Hori ded. 2019 [printed, red]”.

S., / Sagaing Region, MYANMAR / May 29, 2018 / Michio HORI & Thanda Moe leg.”, and same type label. 4 males and 5 females with same labels in MHWJ. 1 male, 1 female in MHWJ: “Sa Yoe, near Thet keg yin, / Maharmyaine W. S., / Sagaing Region, MYANMAR / June 6 2014 / Michio HORI & Thanda Moe leg.”, and same type label. 4 females in MHWJ: “Pyon Village, near Ainggyi, / 13 miles from Saw, / Magway Region, MYANMAR / June 8, 2015 / Michio HORI & Thanda Moe leg.” and same type label. 2 specimens in FSKU (for DNA-studies).
Distribution. Myanmar (Sagaing Region, Magway Region).
Etymology. This new species is cordially dedicated to Ms. Thi Tar Oo, Professor at Yezin Agricultural University, Myanmar.
Diagnosis. At first sight the new species resembles C. (I.) juergenwiesneri Naviaux, 1991 and C. (I.) sikhimensis (Mandl, 1982). From C. (I.) juergenwiesneri it differs by the shape of the labrum and the smaller number of submarginal setae (Fig. 17, 18) and the shape of the aedeagus (Fig. 22). From C. (I.) sikhimensis it differs by the larger body size, the presence of a humeral lunule and the shape of the aedeagus (Fig. 23).
Description. Size: Total length (without labrum) 6.5–8.3mm (mean = 7.4mm, n = 33). Head: Dull coppery greenish above; surface smooth, glabrous, with each two setigerous punctures next to the eyes in front and at the centre; shallow longitudinal striae on orbital plates, irregular, transversely waved between and behind on neck; genae greenish, setose and longitudinally striated. Ratio of width of head to width of elytra = 0.8 in medium. Labrum (male Fig. 15, female Fig. 16) short, distinctly wider than long, ratio of length to width = 0.4 in medium; with eight marginal setae, with three teeth, middle one acute, lateral ones obtuse; color yellow with narrow black border. Mandibles yellowish, with four black teeth. Labial and maxillary palpi testaceous, apical segment metallic dark greenish; basal segment of labial palpi with long erected white setae. Antennae slender, long, reaching half of the elytral length in the male, a little shorter in the female; antennomeres one to four dark, metallic greenish; scape with with one long apical seta, the other three antennomeres almost glabrous; antennomeres five to eleven dark blackish brown, dull, finely and evenly pubescent, antennomere eleven somewhat dilated. Thorax: Pronotum slightly shorter than wide (ratio of length to width = 0.9 in medium), sides somewhat rounded between the transversal constrictions; glabrous, lateral margins densely setose; disc with irregular wrinkles, transversely waved medial and before and behind the transversal constrictions; color dull coppery greenish. Proepisternum coppery and setose, mesepisternum black and glabrous, remaining sternae and episternae densely setose, black with coppery luster; mesepisternum of females with a short and shallow longitudinal furrow near the basal margin. Elytra: (Fig. 19–20) parallel-sided, somewhat widened in the middle of female; color dull greenish on the disc, lateral margins shiny black at the shoulders, shiny coppery between shoulder and apical lunule; elytral testaceous maculation consists of a slender humeral lunule, a triangular marginal dot, a small roundish central dot and a slender apical lunule. Surface with a fine microsculpture of blue, coppery bordered, and evenly spaced punctures; coppery area lighter at apical lunule and darker in a longitudinal area at central dot; apical microserration extremely fine; apical border distinctly rounded and restricted towards middle suture, with a tiny sutural spine. Epipleurae black. Ventral aspect: Venter densely setose, black, with greenish metallic luster; trochanters testaceous; coxae, femora, tibiae and tarsi dark, with blue green luster; legs covered with some setae, mesotibiae more densely setose. Aedeagus: (Fig. 21) on left lateral view slender, straight, slightly enlarged in the middle, with a steady extracted apex (total length 2.3mm).
