ETYMOLOGY. The name is a patronym in honour of Dr. James Hogan (OUMNH), well known specialist in Scaritinae , who helped me regarding type specimens for this and other contributions.

TYPE MATERIAL. Holotype: • ♂, with labels and data: white, black framed, handwritten and printed “c. Plason. JAVA. I.M. ARCHIPEL ” / “Sammlung H. HESSE SMNS 1995 ” ( SMNS) .

REMARKS. The pronotum shows a crack on the right side of the disc and the following body parts are missing: antennomeres 5–11 at both sides, tarsomere five of the right hind leg.

DIAGNOSIS. Asmall sized species with smooth lateral margin of the pronotum and elytron, with no reticulation on the intervals of the elytron, and with one tubercle at base of the interval three. The other two species without any reticulation on the intervals, C. trachys and C. clivinoides , have two tubercles at the base of the elytron, have a distinctly angled lobe of the mentum, and their lateral channel of the pronotum is of equal width.

DESCRIPTION. Measurements. Body length 7.3 mm, width 2.24 mm; ratio length/width of pronotum 0.9; ratiolength/widthofelytra 1.84.

Colour: Glossy. Piceous. Intermediate and hind leg dark fuscous, antenna and tarsomeres fuscous.

Head: Athird narrower than pronotum. Clypeus nearly straight anteriorly; wing prominent, as protruding as clypeus, separated from clypeus by distinct notch and wide furrow; supraantennal plate convex; clypeus laterally with indistinct carina and anteriorly widely reflexed margined, wing and supraantennal plate with usual reflexed margin. Supraantennal plate extended up to mid-eye level, separated from wings by distinct notch. Clypeus transverse, with pentagon-like convexity, separated from frons by moderately deep furrow. Frons moderately convex, with small indistinct pore at middle, with distinct lateral carina at posterior eye-level. Clypeus and frons smooth, separated from wings and supraantennal plate by deep moderately wide furrow continuing posteriorly as wide supraorbital furrow with two supraorbital setigerous punctures at posterior eye level. Neck constriction developed as small step at middle, larger laterally, with row of small punctures. Eye hemispherical projecting. Gena indistinct. Antenna with antennomeres five to eleven missing. Labrum indistinctly convex anteriorly, with meshed reticulation, seven setose. Mentum ( Fig. 45 View Fig ) with isodiametrically reticulated surface, with lobe somewhat concavely hollowed out, shape of lobe suboval, with indistinct short sinuation laterally at tip, epilobe distinctly widened, carinate laterally and anteriorly, carina anteriorly widely removed from margin, with regular carina at middle, median tooth wide, less protruding anteriorly as lobe, pentagon-like.

Pronotum ( Fig. 65 View Fig ): Disk moderately convex in lateral view, slightly more convex anteriorly and basally before declivity, moderately convex in frontal view. Slightly wider than long. Reflexed lateral margin smooth, equally convex, slightly wider in posterior third; anterior angle obtuse, projecting; posterior angle marked by distinct tooth, tooth not protruding laterally over convexity of lateral margin. Lateral channel moderately wide, engraved, indistinctly reticulated. Median line narrow, line-like; anterior transverse line minutely punctured, joining and surpassing median line, just joining basal constriction. Surface smooth, with few longitudinal wrinkles, with indistinct isodiametric reticulation at basal declivity.

Elytron: Disk with slight convexity in anterior half in lateral view, convex on frontal view. Nearly twice as long as wide, indistinctly dilated in apical half with maximum width behind middle. Reflexed lateral margin smooth. Scutellar striole distinct; setigerous tubercle at base of first stria, with small tubercle at base of third interval. Striae moderately deep, punctuate-striate, one to three free at base, four to seven joining at humerus, one running up to apex, not joining with seven, the others ending free at apex. Intervals moderately convex, seventh and eighth with short carina at humerus, eighth carinate at apical quarter. Third interval with four setigerous punctures, first situated at second stria near base, the other three approaching third stria. Surface of intervals and striae glossy, reticulation visible at extreme apical tip only.

Hind wings: Fully developed.

Lower surface: Proepisternum laterally with isodiametric reticulation, smooth towards middle, with flat short wrinkles laterally ( Fig. 80 View Fig ). Terminal sternite of abdomen developed apically as flat moderately broad sulcus.

Legs: Legs covered with longitudinal reticulation. Protibia with three spines of moderate length, with complete carina and sulcus dorsally, movable spur gently curved.

Male genitalia ( Fig. 92 View Fig ): Median lobe long, slender, base broadened, moderately arcuate at middle, straight apically, apex short, spatula-like, apex straight, ventral rim indistinct but visible. Endophallus laterally with elongated band of minute bristles. Ventral paramere wide, distinctly tapered to apex in apical half, slightly arcuate, lateral apophysis somewhat flattened, apex like an asymmetrical spatula, with two long and two small setae at apex. Dorsal paramere slender in its whole length, at apex with alternating two long and two short setae.

Female coxostylus and laterotergite: Unknown.


DISTRIBUTION. Known from the type locality on the Island of Java.
