Sreedevi K. // ICAR- NBAIR -APO 5 ” • 1 ♂ (IECA), “ NE India, S Mizoram st. / Lawnglai Distr., Ngengpuikai vill. / Ngeng Pui N. P., 120–350 m a. s. l. / 20. IV. – 9. V. 2017, St. Jakl lgt. ”. Description of the holotype. (Fig. 10 A – D): Body smooth, clypeus, frons, vertex, pronotum, scutellar shield, elytra and ventrites dark blackish with brown metallic sheen. Measurements: Body length – 7.4 mm, body width – 4.7 mm. Head: Clypeus uniformly punctate with thin margin. Fronto-clypeal suture slightly curved inwardly at center, frons sparsely punctate and depressed slightly in the middle, vertex densely punctate with smaller size of punctures than clypeus and frons. Antenna decamerous, antennal club trimerous, yellowish brown and shorter than funicle. Pronotum smooth with sparse punctures, anterior margin uniformly and thinly bordered and evenly punctured, punctures larger at the center than those of at margin and posterior, anterior angles acute and posterior angles obtuse. Scutellar shield with very minute and sparse punctures, impunctate medially. Elytra shallowly and sparsely punctate. Thoracic and abdominal ventrites: Prosternum minutely and shallowly punctate with conspicuous setae, mesoventrite minutely punctate, punctures larger in middle and gradually decreasing towards sides, metepisternum densely and shallowly punctate, metaventrite minutely punctate. Abdominal ventrites 1–5 sparsely and minutely punctate with tiny setae. Pygidium minutely and sparsely punctate with sparse setae on the posterior margin, dorsal penultimate segment shallow and sparsely punctate. Legs: Protibia tridentate and dentations sharp, proximal tooth smaller than rest. Basal part of protibiae with 2 spines and a single spur at a distance. Sparse setae arranged longitudinally on dorsal side of the protibia. All legs with 5 tarsomeres. Protarsomere 4 smaller than rest while protarsomere 5 longer bearing two cleft claws. Protarsomeres bearing crown of hairs on ventral side. Mesotibia longer and slightly depressed with sparse number of setae arranged longitudinally and bearing two spurs distally. Mesotarsomeres 1–4 decreasing gradually in length and mesotarsomere 1 equals to mesotarsomere 5. Metatibia longer and rugose with two tibial spurs at the end. Metatarsomeres 1–4 decreasing gradually in length, metatarsomere 5 equals metatarsomere 1 in length and bears two equal cleft claws at apex. Aedeagus (Fig. 10 E – H): Parameres asymmetrical with presence of small granules on dorsal surface, left paramere shorter than right, distal margin of right paramere curved externally. Another curve starts gently towards distal region and line of dentations arranged along the curved line with numerous dentate structures scattered to the right-side area of the curved line, curved margin joining to the distal end with numerous crown setae arranged in a line. Female unknown. Differential diagnosis. Based on the external morphology and the shape of male genitalia, the species belongs to the Apogonia apicalis species group as defined by Kobayashi and Lien (2021) and Bezděk (2025). It differs from all known species of this group by the presence of small, but well visible granules on the dorsal surface of both parameres (see Fig. 10 F). Etymology. The species is named after the parameres character, where the right and left parameres are unequal. Distribution. India: Mizoram.
