Revision of the Neotropical species of Trichacis Foerster (Hymenoptera: Platygastroidea: Platygastridae), with description of 24 new species Author Arias-Penna, Tania Milena Author Masner, Lubomir Author Delsinne, Thibaut text Zootaxa 2012 3337 1 56 journal article 10.5281/zenodo.281325 706d7536-7046-48ee-a586-a7bd417b58eb 1175-5326 281325 Trichacis ariaspennae Buhl 2011 Trichacis ariaspennae Buhl 2011 : 121 , 122. Original description. Diagnosis. Occiput medially smooth, laterally dull reticulate-coriaceous with vertical elements; hyperoccipital carina distinct and complete; OOL:LOL = 3:3.5; distance between posterior ocellus and hyperoccipital carina longer than diameter of posterior ocellus; notaulus strong, ending abruptly very shortly before reaching anterior margin; mesoscutum with very few setae, smooth except for reticulation in anterior 0.2; mid lobe posteriorly narrowly pointed, slightly prolonged to base of mesoscutellum; combined length of T3–T6> T2 ( Buhl 2011 and pers. comm. ). The female holotype (the only specimen currently known) was collected in Brazil and was deposited at BMNH ( Buhl 2011 ). Trichacis ariaspennae has a complete hyperoccipital carina, but differs from other species with this character because: T kaulbarsi n sp. has the notaulus absent; T clypeata n. sp. has a projected clypeus fused with interantennal process; T. proximata n sp. has posterior ocellus very close to, almost touching hyperoccipital carina; T. triangulata n. sp. and T. costaricencis n. sp. have combined length of T3–T6 <T2.
