GUATEMALA : Huehuetenango Department : San Antonio Huista ( Buenos Aires ) (latitude: 15.610; longitude: 91.742; 1192 masl ). Etymology. The epithet refers to the Jakaltekan people who live alongside the border of the State of Chiapas in southern Mexico and in northwestern Guatemala . This new species is dedicated to them. Floral records. Hyptis tomentosa Poit. ( Lamiaceae ) and Senna pallida (Vahl) H. S. Irwin & Barneby ( Caesalpiniaceae ). Distribution. GUATEMALA : Huehuetenango Department : Jacaltenango. MEXICO : Chiapas State : Amatenango de La Frontera, Chiapa de Corzo, La Concordia, Tonalá. Oaxaca State : Santo Domingo Zanatepec. NICARAGUA : Rivas Department : Cárdenas, San Juan del Sur ( Fig. 19 ). Comment. The female of Centris jakalteka sp. nov. is similar to C . maya sp. nov. , differing from it by the clypeal surface (disc shiny with an irregular perpendicular unpunctated area in the middle in C . jakalteka sp. nov. ( Fig. 1 ); strongly coriaceous, with coarse and dense punctation on disc, sparser near upper margin in C . maya sp. nov. ( Fig. 9 )), by the punctation on T4 (relatively uniform except at distal margin in C . jakalteka sp. nov. ( Fig. 4 ); fine and dense on anterior half, scattered towards distal margin in C . maya sp. nov. ( Fig. 12 )), by the shape of the central area of the epistomal suture in relation to the central lower margin of clypeus (more arched in C . jakalteka sp. nov. ( Fig. 1 ); almost equally arched in C . maya sp. nov. ( Fig. 9 )), and by the morphology of the primary and secondary basitibial plates (both plates relatively rhomboidal with rounded lateroinferior margins in C . jakalteka sp. nov. ( Fig. 3 ); primary plate elliptical and secondary relatively rhomboidal in C . maya sp. nov. ( Fig. 11 )). The male of this new species differs from the true C . lutea , among other characters, by the position of the second mandibular tooth (equally distant from the other teeth in C . jakalteka sp. nov. ( Fig. 7 ); closer to the third tooth in C . lutea ), and by the pubescence on the dorsal surface of the mesepisternum (light yellow in C . jakalteka sp. nov. ( Fig. 6 ); blackish in C . lutea ).
