Diagnosis. Resembling H. halensis sp. nov. with its silky green pronotum and the mediolateral and anteroapical elytral impressions, but clearly differs by extended black colouration of distal femoral apices (one third to half of profemora), slightly elongated male labrum, and lack of considerably protruding crown-shaped sclerite at dorsoapical aedeagus.

Etymology. Derived from ancient Greek prefix a- (without) and basileía (crown) referring to the absence of the protruding crown-shaped sclerite of the aedeagus.

Description. Body size: Length 11.1–13.4 mm (without labrum), width 3.4–4.2 mm ( Figs. 30–31 ).

Dorsal surface of head greenish with more or less expanded bronze colouration on frons and occiput, temples blue. Frons with transverse or irregular grooves, crumpled wrinkles in transition to vertex. Vertex medially with irregular longitudinal striation converging in transition area to the orbital plates. Orbital plates with fine, curved to parallel converging striae, and with two setae on each side. Occiput with transverse grooves, anteromedian irregularly rugose. Genae glabrous and shallowly grooved, violet-blue with iridescent green anterior apex. Clypeus glabrous, bronze-green with two anterior blue spots. Labrum pale testaceous with dark margin to dark testaceous, with four setae, five apical teeth, and one lateral tooth on each side, three median teeth acute, third apical teeth reduced, shape variable, male labrum short, but slightly extended anterior (0.63–0.68 mm long, 1.43–1.55 mm wide, Fig. 32 ); female labrum antero-triangular (0.88–1.00 mm long, 1.38–1.63 mm wide, Fig. 33 ). Mandibles laterally pale testaceous, darkened areas on inner side, apical teeth dark rufous-brown to black, inner teeth rufous-brown to black. Labial and maxillary palpi testaceous with dark-brown to black terminal palpomeres, in females pre-terminal maxillary palpomeres dark-testaceous. Antennae slender, extending back over the first third of the elytra, metallic black, scape, pedicel, and apices of antennomeres 3–4 dorsally with slightly green or violet lustre, pedicel testaceous at base, scape with a single apical seta, antennomeres 3–4 with few scattered setae, antennomeres 5–11 finely and evenly pubescent.

Thorax entirely glabrous. Pronotum iridescent green with more or less expanded bronze areas, median line moderately pronounced with blue margin, proportions variable, usually slightly longer (2.05–2.73 mm) than wide (2.05–2.55 mm), shallow transverse grooves, pronounced anterior and posterior sulci, anterior lobe wider than posterior, lateral margins of the median lobe moderately converging to the base. Episterna violet-blue, anterior proepisternal margin green and metepisternum with bluish-green lustre. Prosternum, posterior mesosternum, metasternum, and epimera iridescent green, anterior prosternal margin iridescent bronze, anterior epimeral margin blue.

Elytra elongate, length 7.1–8.5 mm, slightly dilated laterally to almost parallel, maximal width posterior, colouration green with yellow-bronze lustre to completely bronze, lateral margin violet to bluish-green, apex green to bluish-green, juxtahumeral, discal, mediolateral, anteroapical, and apical impression considerably pronounced, impression on posterior declivity moderate or lacking, posterior gibbosity significant, basodiscal convexity slightly pronounced, blue punctures slightly decreasing in size from base to apex, punctures fused to transverse lines, converging to apex on anteroapical impression, basal and apical irregularly punctured.

Coxae dark-testaceous with iridescent green or blue-green lustre, pro- and mesocoxae anteriorly, metacoxae laterally densely covered with long white setae, mesocoxae posterior with few white setae. Trochanters and femora testaceous. Femoral distal apices, tibiae, and tarsi metallic-black with some slightly violet-blue or green lustre, profemoral dark colouration extended over a third to half of the distal apex. Claws rufous-testaceous.

Abdominal sternites glabrous (apart from few long setae at posterior margins, and some minute setae at posterolateral margins of sternites 3–5), dark-brown with violet-blue to blue-green reflections, anal sternite with darktestaceous apical margin ( Fig. 34 ).

Aedeagus arched, length 2.63–2.65 mm, medioventral convex, dorsally curved, but dorsomedian relatively straight, apex moderately bent ventrally, with round tip, aedeagal base rather stretched and gently sloping. Inner sac in left lateral aspect medioventral with elongate vertical sclerite and median with short diagonal sclerite, in right lateral aspect with some dorsoapical spikes protruding the apical orifice ( Figs. 35–36 ).

Distribution. Central PHILIPPINES (Negros).
