DIAGNOSIS: Recognized by the following: unique dark brown and yellow-orange color pattern; females with prominent paragenital opening on the right side of the abdomen within sternite II. The male of falsicoleus is unknown. C. falsicoleus , nakatanii and sommelieri are the only species with a prominent paragenital opening within the second abdominal segment, which in falsicoleus and sommelieri extends into the abdomen as a sclerotized copulatory tube. In the latter however, this copulatory tube is corkscrewed while in falsicoleus it is not.

DESCRIPTION: COLORATION (figs. 4, 6): Mostly dark brown with yellow markings. Head: Mostly dark brown, vittae faintly present on frons; mandibular plates yellow; maxillary plates and gena dark brown; buccula brown basally, pale along ventral margin; labrum light brown; labium light brown, dark brown apically. Antenna: AI dark brown, lighter brown basally; AII dark brown with two yellow bands, one broad band subbasally, and another, thinner band subapically; AIII and AIV dark brown, yellow basally. Thorax: Pronotal collar yellow; pronotum dark brown with median yellow stripe, posterior of humeral angles yellowed; thoracic pleura dark brown, posterior margins yellowed; mesoscutum dark brown; scutellum dark brown with three yellow spots laterally and apically. Hemelytra: Dark brown, claval commissure yellowed, corium with faint yellow U-shaped pattern. Legs: Pro- and mesofemur yellow, becoming dark brown at apex; metafemur brown, yellow basally, with 8–9 diagonal yellow stripes on outer surface; pro- and mesotibia with basal half dark brown, apical half yellow; metatibia dark brown; tarsi yellow. Abdomen: Chestnut brown, upper margins of each sternite dark brown, bordered posteriorly by yellow. SURFACE AND VESTITURE (figs. 4, 6, 13A): Head, pronotum, propleuron, metepimeron (fig. 20A), scutellum, hemelytra, and cuneus finely punctate; head and dorsum clothed in long, white, decumbent setae. STRUCTURE (figs. 4, 6, 13A): Head: Frons weakly tumescent medially, swelling of frons merging with minor medial swelling on vertex; posterior margin of vertex carinate and rounded. Thorax: Pronotum steep, posteriorly round- ed, anterolateral margins not upturned, submarginal region of humeral angles strongly excavated, callar region undifferentiated; proepisternum bilobed; posterior margin of metepimeron extended as a short, broad, rounded lobe (fig. 13A); metanotum prominent and flared; scutellum flattened. Hemelytra: Embolium carinate and flared outward posteriorly. Legs: Metatibial spines long and thick. Abdomen: When viewed laterally, posterior margin of sternite II sharply angular. MALE GENITALIA: Unknown. FEMALE PARAGENITALIA (fig. 13A– B): Right abdominal sternite II with prominent paragenital opening, partly obscured by metepimeral lobe (fig. 13A–B), forms a thinly

sclerotized invagination into the abdominal cavity.

ETYMOLOGY: Derived from Latin (falsi-, ‘‘false’’, and coleus, ‘‘sheath’’ and thus ‘‘vagina’’), the species name falsicoleus refers to this species’ prominent paragenital opening.

HOST: Unknown.

DISTRIBUTION: C. falsicoleus has only been collected in Sabah (map 5).
