More new records of spider wasps from Colombia (Hymenoptera, Pompilidae)

Abstract Aporinellus Banks, Austrochares Banks and Dicranoplius Haupt are new generic records for Colombia, as well as the species Dipogon ariel Banks, Evagetes peruana Banks, and Euplaniceps notabilis (Smith). Five new combinations are formally endorsed: Aimatocare argentinica (Banks), comb. n.; Aimatocare longula (Banks), comb. n.; Aimatocare imitator (Evans), comb. n.; Aimatocare impensa (Evans), comb. n.; Aimatocare vitrea (Fox), comb. n. Although these names have been used in Pompilidae, no formal nomenclatural act had been proposed. The presence of Chirodamus paramicola Roig-Alsina, previously reported with uncertainty, is confirmed. Finally, a new combination for Euplaniceps notabilis (Smith), comb. n. is proposed based on molecular phylogenetics and morphological data. The Colombian fauna of Pompilidae sums up to 38 genera and approximately 150 species.


Introduction
The mostly solitary spider wasps (Hymenoptera: Pompilidae) are a widespread group of more than 1,000 species in four subfamilies and 60 genera in the Neotropics (Fernández 2000, Hanson andWasbauer 2006). Despite some recent progress in the taxonomic study of Neotropical pompilids (e. g. Rodriguez et al. 2010, Waichert et al. 2012, Waichert et al. 2015, their nomenclature and systematics remains incipient. As a result, several genera lack identification keys and urge taxonomic revision, and many species remain to be described. With the growing anthropogenic pressures on the Neotropical forests, one of the main concerns is the loss of biodiversity, which increases the need of prioritizing taxonomic studies in these areas. The authors are currently engaged in the monograph of spider wasps from Colombia, including keys to subfamilies, tribes, genera and species of several genera. This endeavor favored the publication of new genera and species records (Castro-Huertas et al. 2014). Because we are approaching the completion of the book's manuscript, it is desirable to publish some additional new records of genera and species, as well as relevant nomenclatural acts, as a separate note from the forthcoming book.
To date, the fauna of spider wasps from Colombia has 150 known species, belonging to 38 genera and four subfamilies.

Results
The following species and genera are reported for the first time in Colombia. Comments. This is the first record of the genus for Colombia and northern South America. The known distribution of Aporinellus is worldwide, except Australia (Evans 1966). The studied specimens probably belong to an undescribed species that will be studied elsewhere. Comments. This is the first record of the genus for Colombia and northern South America. Austrochares was previously known from Mexico to Argentina, including Brazil, Chile, and Peru (Evans 1969). The studied specimen keys out to A. mexicanus in Evans's (1969) key, but it probably belongs to an undescribed species that will be further studied elsewhere. Comments. This is the first record of the genus for Colombia. Dicranoplius is restricted to the Neotropics, to both temperate and tropical South America. It was previously known from Trinidad south to Argentina (Evans 1969). The studied specimens key out as D. areatus in Evans's (1969) key, but they belong to an undescribed species, which will be described elsewhere.
Comments. This is the first record of this species for Colombia. Euplaniceps notabilis was previously recorded from Mexico to Costa Rica (Evans 1966). The new combination is proposed based on molecular phylogenetic analyses (Rodriguez et al. 2015), which included A. notabilis (labeled "Euplaniceps sp.", voucher PO484) in the Euplaniceps clade, sister to the Antillean Drepanaporus. This species had previously been included in the genus Odontaporus by Bradley (1944) based on the presence of a tooth in the margin of the inferior mandible and bare eyes. Bradley (1944) did not mention the presence of this tooth in many Euplaniceps species (see Colomo de Correa 1998). Evans (1966)

included this species in
Aporus based mainly on the second submarginal cell receiving only one recurrent vein. This character is very variable even within Euplaniceps species (JR pers. obs.), where the second submarginal cell can receive one or two recurrent veins, with the second recurrent vein sometimes being interstitial with the second intercubital vein. Moreover, females of A. notabilis do not have a v-shaped spatium frontale as all other Aporus, but a flattened area between the antennal alveoli on the same plane as the clypeus which is found in many Euplaniceps species (see Colomo de Correa 1998). Finally, the male genitalia have parameres with parallel-side edges and truncated apex, which is a diagnostic character of Euplaniceps males. The two subspecies, A. n. notabilis and A. n. pulchritarsis, are herein included in Euplaniceps.
Comments. This is the first record of this species for Colombia and east of the Andes. Evagetes is most diverse in the Holarctic region, having South American species occurring west of the Andes (Argentina, Chile and Peru) (Evans 1966;Fernández 2000). This species was previously known from Trujillo, Peru (Banks 1947).
Comments. Fernández (2000) cited the occurrence of P. formosum hondurense Dreisbrach, 1950 in Colombia (Orinoco region), without providing specimen data and/or specimen voucher. We add a female specimen to this species' range. Priochilus formosum hondurense is known from females only and had been known from Honduras to Costa Rica (Evans 1966).
Comments. Roig-Alsina (1984) recognized five species mostly from southern South America, with one species, C. paramicola, in Venezuela and Colombia. The holotype and paratypes are from the Venezuelan Andes, and the single specimen from Colombia was collected in Nariño (southwestern Colombia) and deposited in London without further study. We found a new specimen from Chingaza Park, which slightly differs from the type series by having different fore leg coloration. The Colombian specimen studied here comprises a possible geographical and morphological bridge between the Merida (Venezuela) and Nariño specimens.
Comments. This is the first record of this species for Colombia. Dipogon ariel was previously known from Ecuador (Banks 1946).
