Diagnostic description.

White patch on gena: extending to occiput but not to clypeus. Tegula/humeral complex color: yellow/yellow. Mesonotum color: mostly dark brown to black. Metasoma color: with several tergites orange-yellow, some laterotergites and sternites yellow, rest mostly brown. Tarsal claws spines: 4. Pterostigma shape: comparatively less elongate, its length ≤ 2.5 × its central height and usually more rounded with at least one of its lower margins curved. T1 sculpture: weakly sculptured along margins. T1 central ridge: marked by two raised carinae and strong costulae centrally. T2 sculpture: weakly sculptured along margins. Ovipositor sheaths length: longer than first segment of metatarsus. Body length: 4.1-4.5 mm. Fore wing length: 4.2-4.5 mm.

Notes.

The associated BIN includes at least three (possibly more) species, see further explanations and details under the treatment of Alphomelon melanoscelis . Two ACG specimens (DHJPAR0026274 and DHJPAR0049249) have a darker coloration (they look similar to A. andydeansi and thus they would end in a different place of the key) and also have different DNA barcodes. They are excluded from the type series.
