Allocota cyanipennis Heller 1923: 305 (original: Allocota ; type locality: Mindanao; holotype deposited in SNSD); Andrewes 1930d: 13 ( Allocota ; catalogue); Jedlička 1963: 306 ( Allocota ); Kirschenhofer 1996: 763 ( Allocota ).

Type examined.

Holotype of Allocota cyanipennis Heller, monotypy (SNSD): male, body length = 6.3 mm, board mounted, "Tangcolan / Bukidnon /Baker"; " cyanipennis / Typus" [red label]; " 14261 "; "1921 / 3 " [yellow label]; "Staatl. Museum für / Tierkunde, Dresden"[Fig. 50].

Notes on types.

Heller (1923) didn’t clearly state this species was based on a single specimen, but he only cited one specimen with a serial number “14261”. So, the holotype ( Fig. 50 ) was originally fixed by monotypy, as the description implies a single specimen.

Non-type material examined

(Total 5 specimens). The Philippines: 1 specimen (NHML), "Philippine Is., Coll. Bottcher., B. M. 1929-201". 1 male (NHML), "Island of Basilan, Baker"; "Ex Mus. Coll. Agric. Phil. Is."; "Allocota cyanipennis Heller, Compared with type H. E. A."[Figs 16, 81]. 1 specimen (NHML), "Tangcolan, Bukienon, Baker". Sulawesi: 1 male and 1 female (NHML), “Celebes”.

Diagnosis.

Elytra metallic blue; metasternum and abdomen much darker than prosternum; front angles of pronotum with setae relative long ( Fig. 152 ); elytral 7th interval without setigerous pores; internal sac of aedeagus with setose area divided into three parts, apex of secondary flagellum forming a large triangular sclerite.

This species is closest to Allocota viridipennis Motschulsky; differences are presented in the diagnosis part under the latter species.

Description.

Body length 6.3-7.1 mm; head and pronotum orange red or brown; mouthparts earth yellow, palpomeres brownish, apex of terminal palpomeres yellow; 1st antennomere reddish, the remaining antennomeres usually slightly darker; elytra metallic blue, elytral suture and lateral margins metallic; legs usually much darker than pronotum, darkest on apical half of femora, basal half usually the same color as pronotum; ventral side of head and prosternum the same color as dorsal side; metasternum and abdomen brownish to piceous, much darker than prosternum. Head glabrous, without punctures, microsculpture indistinct; males with terminal labial palpomeres fusiform, slightly expanded in middle. Pronotum glabrous,cordiform, widest at anterior third; ratio PW/PL 1.28 to 1.32; pronotal base briefly but distinctly lobed; disc moderately convex, microsculpture indistinct, without punctures; front angles with setae relative long ( Fig. 152 ); lateral margins rounded, slightly expanded in middle, strongly sinuate before hind angles; lateral explanate areas moderately wide, without punctures; hind angles slightly acute, less distinct; basal foveae very shallow, without punctures; median line very fine, usually indistinct. Elytra with striae very shallow, finely punctate; intervals nearly flat, without accessory setae, with a row of very fine punctures; microsculpture absent; 3rd and 5th intervals with four to ten setigerous pores, their positions variable; 7th interval without setigerous pores; setae on lateral margins fine and short, but more distinct than in Allocota viridipennis . Legs. Protibiae with cleaning spur absent ( Fig. 140 ); males with adhesive hairs well developed (two whole rows) on first two mesotarsomeres, rudimentary (two rows, weakly present near apex) on 3rd mesotarsomere. Male genitalia with median lobe of aedeagus stout, more distinctly bent to right side near apex than in Allocota viridipennis in dorsal view, right margin slightly curved before apical lamella; apical lamella placed on right side, narrow, slightly elongate; internal sac with setose area divided into three parts; apex of secondary flagellum expanded, formed a large triangular sclerite; trumpet-form expansion with ventral margin more or less expanded. Female genitalia not studied ( Fig. 81 ).

Distribution

( Map 6 ). The Philippines, Sulawesi.

Geographical variation.

Pronotum and head of two specimens from Sulawesi we examined are brown, much darker than those from the Philippines which are vivid orange.

Remarks.

We regard specimens from the Philippines and Sulawesi as a distinct species from Allocota viridipennis Motschulsky for the constant difference in internal sac of aedeagus as mentioned above in the diagnosis section under Allocota viridipennis . In external characters these two species are very similar, with only slight differences in setae on pronotal front angles ( Figs 151, 152 ) and elytral lateral margins.
