Description. Overall coloration stramineous to olivaceous in sub-macropterous male and female ( Fig. 1 View FIGURE 1 A–B, E–F) to dark-brown in macropterous female ( Fig. 1 View FIGURE 1 C–D). Head wider than protonum; crown stramineous with two pairs of small black sports on anterior margin, inner pair next to midline and lateral near ocelli; longer than width between eyes; eye wider than distance between eyes; anterior margin forming acute angle in dorsal view. Face, yellowish with brown marks; frontoclypeus with many transverse arcuate dark-brown stripes, stripes wider on top than basally, midline with interrupted yellowish vertical band, broad basally; anteclypeus yellowish laterally, brownish centrally; gena yellowish, in some females brownish distally ( Fig. 1 View FIGURE 1 G–I). Pronotum stramineous, wider than long; scutellum, flat in lateral view, short, fully yellowish in submacropterous individuals ( Fig. 1 View FIGURE 1 A–B); forewing in males reaching posterior margin of tergite V or VII in repose, in females usually tergite VII and VII uncovered; venter and abdomen black preapically; genital capsule light stramineous with black or pale macrosetae ( Fig. 1 View FIGURE 1 E–F).

Macropterous female with face darker, anteclypeus with a apical half black, gena with black band below eyes, pronotum with four longitudinal brownish lines, mesonotum with basolateral triangles black, venter and abdomen brown ( Fig. 1 View FIGURE 1 C–D).

Phenology. Specimens collected throughout dry (October-March) and wet season (June-September) in Mexico, highest abundance was reported in December ( Moya-Raygoza & Becerra-Chiron 2014; Pinedo-Escatel & Moya-Raygoza 2015, 2018).

Biological notes. Not reported as vector of any plant pathogen (treated as Amblysellus   sp. in Torres-Moreno et al. 2015, vouchers examined).

Natural enemies. Parasitized by dryinids, Gonatopus   spp. ( Becerra-Chiron et al. 2017, considered as Amblysellus   sp., vouchers examined).

Etymology. This is species is named in honor of Prof. Dr. Gustavo Moya Raygoza, University of Guadalajara.

Distribution. Mexico, restricted to Las Agujas and Cd. Guzmán, both localities from Jalisco state ( Fig. 4 View FIGURE 4 ).

Host reported. Cynodon dactylon   , C. plechtostachyus   , Brachiaria plantaguinea   , B. brizantha, Eulesine   indica, Chloris gayana   , Digitaria ciliaris   , Melinis mutiflora, Eragrotis   curvula, Panicum maximun   , and Rhynchelytrum repens   ( Moya-Raygoza & Becerra-Chiron 2014; Pinedo-Escatel & Moya-Raygoza 2015, 2018).

Remarks. The new species, A. raygozai   , is similar in dorsal appearance to A. necopinus   , but it can be recognized easily by the more angulate anterior head margin, presence of small (not large) spots on the crown, and the evenly curved aedeagus with blunt apex.

Notes. Many specimens of A. raygozai   were observed feeding and mating on the same host-plants of the related species, A. necopinus   .
