Diagnosis.
Stoiba indivisa
(Figs 29-31) is distinguished from
Stoiba bruneri
by pale antennae, from
Stoiba clarildae
by moderately convexprofile, and from
Stoiba flavicollis
by hemispherical pronotum without anterior margin angle. It also differs by a more emarginate pronotum anterior margin than other species and by elytra dark blue (in naked eyes) to purple (under microscope) with posterior half of margin indistinct.
Description.
Adult (n=5) length 6.5−6.7 mm, width 5.5−5.7 mm. Body (Figs 29-31) oval, widest at near middle in dorsal view. Head, antennae, pronotum, and legs brown with pro- and meso-femur proximal end black; meta-femur brown with proximal 1/3 black; elytra dark blue to purple and slightly opalescent. Head withdrawn into prothorax except entire eyes and epicranial suture exposed in dorsal view; inter-ocular area 2 times as broad as eye, slightly depressed medially; maxillary palpus (Fig. 60) and labial palpus
(
Fig. 62) compact. Pronotum (Figs 7, 29) hemispherical, brown with base line black; base 2 times as broad as anterior edge; anterior edge moderately emarginate, anterior 2/3 of lateral edge gradually broader, curved at posterior 1/3; margin moderately defined, sparsely punctate. Procoxal process (Fig. 31) slightly convex, shiny, black. Scutellum triangular, shiny black. Elytra (Fig. 30) moderately convex with surface scale-like, shiny, finely and coarsely punctate; umbone moderately projected and angled; margin distinct in anterior half and vague in posterior half. Hind wing fully developed. Legs (Fig. 31) brown with coxae, trochanters, proximal end of pro- and mesofemur, proximal 1/3 metafemur black.
