Balaninus chevrolati Faust 5 ( interruptus Chevrolat nec Kirsch) 1893: 146. Recognition Characters. Medium­sized, elongate oval; derm piceous; rostrum, 0.59 as long as body; hind femoral tooth large­sized, wedge shaped; elytra with macular fascia of narrow, elongate, white, scales at midpoint on intervals 2–10; scutellum flanked by macula of narrow, elongate, white scales; scutellum piceous; interval one with short distal vitta of clavate, cretaceous scales. Description. Male. Length: 4.2–4.3 mm (mean 5 4.25). Width: 2.2–2.3 mm (mean 5 2.25). Head: Medium­sized, moderately convex; punctures small, shallow, and glabrous; eyes large, moderately convex, finely faceted, partially covered by anterior margin of pronotum. Frons broad, 0.23 as broad as head across eyes; small, deep interocular fovea; Rostrum: Length: 2.5 mm ; 0.59 as long as body; cylindrical; margins subparallel, broad at base gradually tapering to apex; dorsally three carinae from frons to antennal insertion, punctures between carinae oval; straight to antennal insertion then gradually curved to apex; scrobe ventral; scape inserted in apical half. Antennae: Length: Scape 1.1 mm ; Funiculus: segment one 0.3 mm , two 0.25 mm , three 0.15 mm , four 0.1 mm , five 0.1 mm , six 0.1 mm , seven 0.15 mm , club 0.5 mm ; funicle 1.3 mm ; scape 0.85 as long as funicle; clothed with elongate, cretaceous scales; club elongate, oval, compact, acuminate, clothed with velvety pile, with few erect setae, longer than funicular segments 4–7. Thorax: Length: 1.4 mm . Width: 1.8 mm ; disc with indication of median longitudinal carina, margins subparallel, broadly rounded to constriction; almost as broad at base as elytra; disc glabrous except for anterior cretaceous macula on pleuron just behind head, basolateral macula continuous with fascia on elytra past scutellum forming V shaped white fascia; anteroventral macula of short, broad, clavate, cretaceous scales between procoxae; mesosternal intercoxal process very prominent, densely clothed with short, broad, cretaceous scales; scutellum small­sized piceous, as long as broad, with short, narrow, elongate, testaceous scales; mesepimeron densely clothed with short, broad, clavate, cretaceous scales; mesepisternum sparsely clothed with broad, clavate, cretaceous scales; metepisternum clothed with short, broad, piceous scales, anteriorly, with dense macula of broad, clavate, cretaceous scales, posteriorly; procoxae clothed with cretaceous scales. Elytra: Length: 2.5 mm . Striae deep, with deep punctures, clothed with small, narrow, elongate, piceous scales; shallow scutellar declivity; humeri prominent, rounded; disc slightly convex in lateral view; intervals broad, flat clothed with piceous scales; cretaceous macular fascia on each side of scutellum on intervals 1–4 meeting basal macula on pronotum above intervals 5–8; at midpoint macular fascia of clavate cretaceous scales on intervals 2–10, in some specimens interval four lacks macula; short vitta on interval one of short, broad, cretaceous scales in distal quarter to apex; crosshatched setae long, erect and piceous. Legs: Length of hind femur 2.1 mm , tooth large­sized, wedge shaped, with proximolateral sulcus from base to club; pro and mesofemoral tooth small; all legs clothed with narrow, elongate, cretaceous scales; tibiae straight, margins subparallel; pro­, mesouncus small not as long as tarsal claw, with acute apex, metauncus small with blunt apex. Abdomen: Sternite 1 longer than 2 behind coxal cavity; sternites 1 and 2 with shallow median declivity; sternite 2 ascending to 3; 3 and 4 equal in length, combined exceed sternite 5 in length; sternite 5 emarginate with apical declivity, with fringe of ochraceous seta­like scales ventrally and lateral tufts of cretaceous seta­like scales dorsally; all sternites clothed laterally, with broad, clavate, cretaceous scales and medially with narrow, elongate, cretaceous scales. Pygidium: Small , barely visible with cretaceous seta­like scales. Genitalia: Median lobe of aedeagus 1.0 mm in length, 0.2 mm in width, slender with thin margins dorsally tapering to narrow acute apex, in lateral view apex curving posteriorly; aedeagal apodeme 0.8 mm in length ( Figs. 73–75 ). Distribution. China : Hainan Island Province, Dwa Bi, 20 July 1935 , Ta Hian, 15 June 1935 , J. L. Gressitt; Borneo: Kuching, 1910, Lewis. Two specimens were examined on loan from CASC, four from BPBM, and one labeled Curculio interruptus Kirsch and two labeled C. chevrolati on loan from BMNH. Remarks. This species looks similar to Curculio klapperichi Voss , but differs in length of hind femur exceeding apex of abdomen and placement of basolateral cretaceous macula on pronotum, which extend above the seventh interval of the elytra. Curculio nagaoi Morimoto (1981) also looks similar except for cretaceous scaled scutellum.
