description: Calochroa horii Wiesner and Phyu, new species
(Fig. 1)
Type depository. Holotype male in OMNS, one paratype female each in JWGC, DARM and YAUM, two paratype females in MHWJ.
Type status. Holotype male, type labels: “ 5 km W from Ainggyi (teak / plantation), Magway Region, / MYANMAR / May 31, 2018 / Michio HORI & Thanda Moe leg.”, “ HOLOTYPE / Calochroa / horii new species / Wiesner & Phyu ded. 2019 [printed, red]”.
Paratypes: 1 female each with same label in JWGC, DARM, and YAUM, and “ PARATYPE / Calochroa / horii new species / Wiesner & Phyu ded. 2019 [printed, red]”. 2 females with same labels in MHWJ.
Distribution. Myanmar (Magway Region).
Etymology. This new species is cordially dedicated to one of its discoverers, Prof. Dr. Michio Hori.
Diagnosis. Similar to Calochroa schillhammeri Wiesner, 2004, distinguished by the colour of the labrum, shape of elytral maculation and aedeagus.
Description. Size: Total length (without labrum) 13.0– 15.7mm (mean = 14.6 mm, n = 6). Head: Glabrous, with two setigerous punctures next to each of the eyes in front and at the centre; clypeus coppery greenish, marginal part of frons near the eyes green, genae coppery green in front and bluish green at base, remainder of head coppery brown or greenish; frons and orbital plates with distinct longitudinal striae, genae with fine longitudinal striae, vertex distinct and irregularly wrinkled. Eyes pale whitish with some small darker areas. Ratio of width of head to width of elytra = 0.7 in medium. Labrum (male Fig. 2, female Fig. 3) distinctly wider than long, ratio of length to width = 0.6 in medium, yellowish, black at margins and at the four setal pits, with five pointed apical teeth, the middle three larger, the outer two smaller. Mandibles yellow, teeth black. Labial palpi yellowish, apical joint black, the distal segments brown. Maxillary palpi yellowish, apical joint black, basal segment of labial palpi with long erected white setae. Antennae slender, reaching back a third of the elytral length in the male, a little shorter in the females; antennomeres one to four dark, with metallic green luster; scape with with one long apical seta, the other three antennomeres almost glabrous; antennomeres five to eleven black, dull, finely and evenly pubescent. Thorax: Pronotum slightly wider than long (ratio of length to width = 0.8 in medium), sides somewhat rounded between the transversal constrictions; glabrous, with white setae at lateral margin; with irregular wrinkles on disc; color brown or greenish, lateral margin greenish or coppery. Proepisternum blue violet, other sternae and episternae greenish black, proepisternum with a few white setae in male, glabrous in females, mesepisternum, metepisternum, mesepimeron and metasternum setose; mesepisternum of females with a longitudinal furrow in the upper half. Elytra: (Fig. 5–7) wider than head with eyes, parallel-sided, apices microserrulate, rounded, with distinct sutural edge; shoulders well marked, subsquare; surface smooth with a fine microsculpture, ground color greenish; elytral testaceous maculations consist of a large comma-shaped apical dot, a triangular central dot subhumeral and humeral dot, all three transversally arranged and connected with each other, the humeral one covering the shoulder. Epipleurae brownish. Ventral aspect: Venter greenish black, abdominal segments setose; coxae with white setae; trochanters testaceous; coxae, femora, tibiae and tarsi dark, with greenish or coppery reflections; legs covered with sparse setae, mesotibiae more densely setose. Aedeagus: (Fig. 4) on left lateral view fusiform, straight, tapering, slightly enlarged in the middle, with a straight, pointed tip (total length 3.9mm).
