03D687A8526E916DFD3BFC0EBA75E766.taxon	discussion	Remarks. The new species described here is closely allied to S. fulvopleuris, sharing the following characteristics: ferruginous mesopleuron and lateral sides of pronotum; inter-antennal tubercle not distinctly pointed; and propodeum black to brownish black. However, it distinctly differs in the following ways: (1) head in frontal view subquadrate (in S. fulvopleuris somewhat circular); (2) inter ocular distance at vertex distinctly shorter than that at clypeus (in S. fulvopleuris inter ocular distance almost same at vertex and clypeus); (3) level of topmost margin of eyes distinctly above the median ocellus (in S. fulvopleuris distinctly below the median ocellus); (4) pronotal collar with weak transverse carina, almost straight (in S. fulvopleuris with strong transverse carina, distinctly curved); (5) mesoscutum and scutellum weakly microcoriaceous, with dense micropunctures (in S. fulvopleuris strongly microcoriaceous, with sparse micropunctures); (6) dorsal side of propodeum irregularly rugose (in S. fulvopleuris apical half of dorsal side of propodeum transversely striated); (7) recurrent vein of fore wing joining to first submarginal cell distinctly away from first transverse cubital vein (in S. fulvopleuris recurrent vein of fore wing interstitial with the first transverse cubital vein); (8) second submarginal cell of forewing almost square-shaped (in S. fulvopleuris second submarginal cell rectangular); and (9) basal half of T 2 micropunctate (in S. fulvopleuris T 2 impunctate).	en	Girish Kumar, Puthuvayi, Amal, Sreedharan (2025): Description of a new species of Spilomena Shuckard, 1838 (Hymenoptera, Crabronidae: Pemphredoninae) from Western Ghats, India.
