Redescription

COLORATION. General body coloration light brown with iridescent green mainly in dorsal surface of head, humeral angles, anterior portion of scutellum, and posterior portion of femur; dorsal surface densely punctured. Presence of pair of pale spots in anterior portion of pronotum; apex of scutellum pale. Legs light brown, with posterior portion of femur distinctly darker. Ventral surface and connexivum merged with pale and brown, variable among individuals.

HEAD. As long as wide; mandibular plates and clypeus subequal. Apex of labium reaching metacoxae; fourth labiomere darker than preceding; proportion of labial segments: I<=III> IV. Antennae light brown; proportion of antennal segments: I<II>III<IV>V.

THORAX. Anterolateral margins of pronotum pale, crenulated, and sinuose; humeral angles acute and laterally produced. Scutellum triangular, frenal portion longer than postfrenal portion; foveae with similar diameter to ocelli. Corium longer than scutellum, reaching posterior margin of abdominal segment VI; hemelytral membrane dark brown surpassing apex of abdomen. Peritreme disc-type, slightly curved anteriorly; metapleural evaporatorium surrounding peritreme, not reaching lateral margin of pleura; mesopleural evaporatorium reaching lateral margin of pleura ( Fig. 3e ); presence of pair of metasternal processes holding apex of labium.

ABDOMEN. Apex of connexival segments acute and projected posteriorly. Abdominal tubercle short, not reaching metacoxae.

MALE GENITALIA ( Fig. 4 ). Pygophore cuplike; anterior opening triangular; dorsal rim concave, with 1 +1 projections; superior layer of ventral rim rectilinear in ventral, with convexity medially; inferior layer of ventral slightly projected; head of paramere half-moon shape, with acute apex, and small projection in lateral view; pseudoclasper reniform, with stried dorsal sculptures. Phallus with thecal shield more than 2 × as long and as wide as basal theca; presence of acute conjunctival processes; vesica grooved medially.

FEMALE GENITALIA ( Fig. 4 ). Valvifers 8 as long as wide, left valvifer 8 usually overlapping right valvifer, posterior margins rectilinear; valvifer 9 rectangular; laterotergites 9 longer than wide, rounded apically, aligned with segment X. Internal female genitalia with capsula seminalis ellipsoid, as long as pars intermedialis; distal annular crest laterally projected, placed slightly before base of capsula seminalis; inner duct slightly longer and thinner than pars intermedialis; outer duct about 2 × as long as vesicular area; ring sclerites absent; 1+1 secondary thickenings of vaginal intima elongated.

MEASUREMENTS. (n =4) Head length: 2.12 ±0.05 (2.07–2.18), width: 2.18 ± 0.05 (2.13–2.24); pronotum length: 2.69±0.04 (2.65–2.73), width: 7.72 ± 0.08 (7.65–7.80); scutellum length: 3.60 ± 0.07 (3.53–3.67), width: 3.70 ±0.23 (3.47–3.93); antennomere length: I 0.47, II 1.44 ± 0.03 (1.41–1.47), III 1.66 ± 0.07 (1.73–1.59), IV 1.64 ± 0.24 (1.40–1.88), V 1.60 ± 0.07 (1.53–1.67); labial segments length: I 1.09 ± 0.03 (1.07–1.12), II 1.44 ± 0.03 (1.41–1.47), III 1.38 ± 0.02 (1.35–1.40), IV 1.06; abdominal length: 4.91 ± 0.03 (4.88–4.93), width: 4.79 ± 0.21 (4.59–5.00); total length: 10.51 ± 0.16 (10.35–10.67).

Remarks

The exact location of NHMUK 010935774 from Timor Island is not given by the labels. We chose to restrict the distribution of species in Indonesia; however, C. javana also probably occurs in Timor-Leste.

Distribution

Indonesia, Philippines (new record), Malaysia (new record) ( Fig. 10 ).
