6D5587D1FF85827BFF61FAA48C94F84C.taxon	etymology	Etymology. The prefix « para » means « similar to » due to the similarity of the galls of the new species to the galls of the decrescens variety of Neuroterus saltatorius, a species described by Kinsey from Arizona.	en	García-Martiñón, Rosa D., Bravo-Cuautle, Samay, Pérez-Torres, Betzabeth C., Aragón-García, Agustín, Equihua-Martínez, Amando, Estrada-Venegas, Edith G., Cuesta-Porta, Víctor, Melika, George, Romero-Rangel, Silvia, Pujade-Villar, Juli (2026): Neuroterus paradecrescens, a new species of oak gall wasp from Mexico (Hymenoptera: Cynipidae: Cynipini). Zootaxa 5757 (3): 294-300, DOI: 10.11646/zootaxa.5757.3.6, URL: https://doi.org/10.11646/zootaxa.5757.3.6
6D5587D1FF85827BFF61FAA48C94F84C.taxon	diagnosis	Diagnosis. According to Kinsey’s descriptions and keys (Kinsey 1923), Neuroterus paradecrescens García-Martiñón & Pujade-Villar sp. nov. belongs to the subgenus Diplobius, known only from the Nearctic region. The new species has a smooth and shining mesoscutum and mesopleura as in the verrucarun, niger and saltatorius complexes. Having F 1 similar in length to F 2, the new species aligns with the verrucarum - niger complexes. However, these complexes have integral galls (entirely detachable in the new species). The saltatorius complex has detachable galls but adults present F 1 2.0 x as long as F 2 (F 1 = F 2 in the new species). The only species of the saltatorius group with elongate galls is N. saltatorius var. decrescens, nevertheless, these galls are distinctly pubescent and do not have a tip on their surface (without pubescence with a visible tip in the new species).	en	García-Martiñón, Rosa D., Bravo-Cuautle, Samay, Pérez-Torres, Betzabeth C., Aragón-García, Agustín, Equihua-Martínez, Amando, Estrada-Venegas, Edith G., Cuesta-Porta, Víctor, Melika, George, Romero-Rangel, Silvia, Pujade-Villar, Juli (2026): Neuroterus paradecrescens, a new species of oak gall wasp from Mexico (Hymenoptera: Cynipidae: Cynipini).

The exit hole is located on the distal dorsal part of the gall. The galls come off the leaf very easily.	en	García-Martiñón, Rosa D., Bravo-Cuautle, Samay, Pérez-Torres, Betzabeth C., Aragón-García, Agustín, Equihua-Martínez, Amando, Estrada-Venegas, Edith G., Cuesta-Porta, Víctor, Melika, George, Romero-Rangel, Silvia, Pujade-Villar, Juli (2026): Neuroterus paradecrescens, a new species of oak gall wasp from Mexico (Hymenoptera: Cynipidae: Cynipini).
