Composition of spider prey captured by the wasp Trypoxylon (Trypargilum) tridentatum tridentatum in two habitats in an oasis in Baja California Sur, Mexico

  • Karina Domínguez (a1) and María Luisa Jiménez (a1)


Trypoxylon (Trypargilum) tridentatum tridentatum Packard (Hymenoptera: Crabronidae) is a spider-hunting wasp in mesic and xeric habitats in the arid Baja California peninsula of Mexico. Spider (Araneae) prey were collected every 2 weeks from wasp trap nests. Individuals of the family Araneidae were the most abundant prey (60.9%), followed by Theridiidae and Mimetidae. Dictynidae, Anyphaenidae, Salticidae, Uloboridae, Tetragnathidae, Miturgidae, and Philodromidae were captured only in the mesic habitat. An unidentified species of Eriophora Simon (Araneidae) was the most frequently collected spider in the xeric habitat (29.0%), followed by Theridion submissum Gertsch and Davis (Theridiidae) (24.0%), which was the commonest prey species in the mesic habitat (21.1%), and Metepeira crassipes Chamberlin and Ivie (Araneidae) (16.5%). Nineteen species and three families are newly recorded as prey. The araneids Araneus lineatipes (O.P.-Cambridge) and Kaira alba (Hentz) and the uloborids Philoponella arizonica (Gertsch) and Uloborus segregatus Gertsch are new records for Baja California.

Trypoxylon (Trypargilum) tridentatum tridentatum Packard (Hymenoptera: Crabronidae) est une guêpe chasseresse d’araignées dans la péninsule aride de la Basse-Californie au Mexique. Nous avons récolté des araignées (Araneae) capturées comme proies dans les nids-pièges des guêpes à toutes les deux semaines. Les proies les plus abondantes consistent en des spécimens de la famille Araneidae (60,9 %), suivie des familles Theridiidae et Mimetidae. Les spécimens de Dictynidae, d’Anyphaenidae, de Salticidae, d’Uloboridae, de Tetragnathidae, de Miturgidae et de Philodromidae n’ont été capturés que dans l’habitat mésique. Une espèce non identifiée de Eriophora Simon (Araneidae) est l’araignée la plus fréquemment récoltée dans l’habitat xérique (29,0 %), suivi de Theridion submissum Gertsch et Davis (Theridiidae) (24,0 %), qui est l’espèce la plus commune de proie dans l’habitat mésique (21,1 %) et de Metepeira crassipes Chamberlin et Ivie (Araneidae) (16,5 %). Dix-neuf espèces et 3 familles sont signalées pour la première fois comme proies. Les aranéidés Araneus lineatipes (O.P.-Cambridge) et Kaira alba (Hentz) et les uloboridés Philoponella arizonica (Gertsch) et Uloborus segregatus Gertsch sont signalés pour la première fois en Basse-Californie.
