Kawada, Ricardo Torrens, Javier Zootaxa 2018 2018-07-17 4446 2 265 272 Torrens 2012 Torrens 2012 [151,534,1897,1923] Insecta Eucharitidae Colocharis GBIF Animalia Hymenoptera 2 267 Arthropoda species hungi   Diagnosis.The female is distinguished by a short FL2, 2.7× as long as greatest width and 1.3× as long as following flagellar segment ( Fig. 2B); propodeal disc with weak, broadly areolate sculpture and petiole with rough surface ( Fig. 2C) and two weak longitudinal carinae and a weak basal carina. The male has a shorter flagellum than  C. napoana(1.3× height of head), a long fore wing (2.4× as long as broad), and the propodeal disc is sharply areolate.   Description. Female.Length 1.9 ‒2.3 mm( Fig. 2E). Head, mesosoma, and petiole black; gaster dark brown; antennal flagellum, pedicel, scape, and legs white; wings hyaline; fore wing venation light brown.  Head. 1.3 ‒1.4× as broad as high. Face, including genae, smooth and shining, with sparse, fine appressed hairs ( Fig. 2A); vertex slightly rugose. Eyes separated by 1.9‒2.0× their height. Malar space 0.6 ‒0.9‒ height of eye. Scape 3.3 ‒4.7‒ as long as wide, elongate and smooth, with scattered semierect hairs in dorsal region; flagellum with 6 segments ( Fig. 2B), length of flagellum 1.3 ‒1.5× height of head, FL2 2.7 ‒3.3× as long as greatest width, 1.3 ‒1.7× as long as greatest length of following flagellar segment; FL2 swollen in apical half; clava elongate, about as long as previous two segments combined ( Fig. 2B).  Mesosoma.Mesoscutum midlobe with irregular carinae radiating from midpoint to posterior margins, evenly covered with fine appressed hairs; lateral lobes smooth and shining, with sparse setae. Axillae and scutellar disc with parallel longitudinal carinae dorsally, lateral face of axilla with some irregular striae, axillula with oblique carinae; frenal process 2.1 ‒3.3× as long as broad. Propodeal disc with weak, broadly areolate sculpture, bordered by propodeal carina ( Fig. 2C). Metacoxa 2.0 ‒2.1× as long as broad, smooth, shining, and bare. Metafemur smooth with semi-appressed setae ( Fig. 2D). Fore wing 2.4 ‒2.5× as long as broad, stigmal vein subquadrate, 1.2 ‒1.4× as long as broad; postmarginal vein indistinct, but apparently a little longer than stigmal vein; entire wing pilose except for basal area.  Metasoma.Petiole 4.7 ‒5.1×x as long as broad and 1.5× as long as metacoxa, cylindrical in cross section with rough surface, with two weak longitudinal carinae and weak basal carina. First gastral segment smooth and bare. Hypopygium with one seta on each side of mucro. Ovipositor sheath extending beyond cerci (and metasoma) by much more than one diameter of the cercus.   Distribution. Argentinaand Brazil( Mato Grosso do Suland Roraima).     Materialexamined. BRAZIL:  Roraima: Amajari, Serra do Tepequém,  1‒15.i.2016, Malaise Gressit-Gressit, Rafael et al. col., 1♀and 2♂, INPA;   Mato Grosso do Sul: Dourados, 22°13’16’’S/ 54°48’20’’W,  26.v.2015, Calhau, Kawada& Coelhocol., 3♀and 14♂ UFES.   Remarks.  Colocharis hungiis recorded, so far, from two distinct biogeographic provinces, ParanáForest and Pantepui provinces ( Fig. 4). Both provinces are structurally dissimilar, with a transition between savannas and humid forests in northern Brazil, with characteristic sandstone plateaus, representing the Pantepui province ( Morrone 2000), and humid and seasonal forests representing the ParanáForest province ( Morrone 2001). Although both provinces present little similarity in fauna and flora ( Morrone 2000, 2001, 2014), we cannot properly infer if historical events and regional characteristics shape eucharitid distribution, since their presence in a specific location could be constrained by other factors, such as host availability and preference for oviposition sites. As long as our knowledge on the biology of this group remains scant we will not fully comprehend the processes that explain their distribution. According to Heraty (2002), there are specimens of Cholochariscollected in Peru, but not for the described species, indicating that the diversity of this genus remains largely unexplored. Undersampling can inhibit our ability to understand the species distribution in many genera of Eucharitidae. Sadly, we do not have standard procedures to enhance eucharitid sampling in poorly studied areas. We still do not have enough phylogenetic and taxonomic support to accurately establish causal relations between biogeographic events and current distribution in most eucharitid genera. 1914122842 2016-01-01 2016-01-15 2016-01-01 INPA Malaise Gressit-Gressit & Rafael Brazil Material Serra do Tepequem Amajari 3 268 3 1 2 Roraima 1914122843 2015-05-26 UFES Calhau & Kawada & Coelho Brazil -22.221111 Dourados 21 -54.805553 3 268 17 3 14 Mato Grosso do Sul
