Type locality. Zempoaltépetl, Municipio Santa María Tlahuitoltepec, 17.10567°N, 96.00120°W, 2583 m, Oaxaca, Mexico.

Holotype repository. Instituto de Ecología , Xalapa, Veracruz, Mexico.

Description. Length 4.5–5.0 mm (holotype length: 4.5 mm); oval elongate, moderately convex, rather shiny, glabrous. Dorsal surface chestnut brown, head anteriorly and sides of pronotum paler; elytra chestnut brown with base of interstriae 2–4 and 6–10 as well as apex yellowish brown; apical declivity including an oblique, oval, yellow spot extended from interstria 2–7 and with margins dark ( Fig. 5, holotype, allotype and most of the specimens of type series), sometimes the margins widely faded ( Figs. 6–7); scutellum yellowish brown with margins darker; legs brown; antennal club dark brown; underside dark brown.

Head with epistome feebly convex, evenly, densely punctate throughout; clypeus slightly sinuate at middle, rounded at sides, rather thickly bordered, edge almost imperceptibly ciliate; genae obtuse, almost imperceptibly ciliate, slightly protruding from the eyes; frontal suture finely impressed, not tuberculate; frons and epistome similarly punctate; first labial palpomere longer than second ( Fig. 8).

Pronotum transverse, moderately convex, simply, densely punctate, with elongate mediobasal area more-or-less impunctate; lateral margins strongly inwardly sinuate before hind angles, thickly bordered, edge with indistinct short cilia; hind angles obliquely truncate; base slightly bisinuate, not bordered.

Scutellum small, triangularly elongate; sparsely, superficially punctate.

Elytra oval-elongate, denticulate at shoulder, finely striate; striae deep, fine, punctate, subcrenulate; interstriae almost flat, distinctly not closely punctate, superficially microreticulate, the second interstria slightly wider than the others.

Protibiae distally tridentate and proximally serrulate on outer margin; upper surface densely and more-or-less coarsely punctate. Metatibiae with feeble transverse carinae on outer face, apically fimbriate with spinules elongate and irregularly unequal; upper spur shorter than metatarsomere 1; metatarsomere 1 longer than metatarsomeres 2–4 combined.

Pygidium distinctly microreticulate, evenly, sparsely punctate; apical margin with few, elongate setae. Aedeagus with parameres rather elongate, apically curved and diffusedly pubescent at apex ( Figs. 3–4).

Sexual dimorphism. Male: protibiae relatively slender, pronotum more transverse, metasternal plate with median longitudinal groove deep. Female: protibiae relatively stouter, pronotum less transverse, metasternal plate with median longitudinal groove more superficial.

Distribution. Oaxaca, Mexico.

Etymology. Named after the type locality.

Bionomics. Specimens of the type series were collected from the end of May until September. In San Pablo Etla G. zempoaltepetlensis was collected together with Agrilinellus azteca (Harold, 1863) ( Coleoptera : Scarabaeidae : Aphodiinae : Aphodiini ), Onthophagus zapotecus Zunino & Halffter, 1988 , O. chevrolati Bates, 1889 ( Coleoptera : Scarabaeidae : Scarabaeinae : Onthophagini ), and Canthidium quercetorum Kohlmann, Arriaga-Jiménez , & Rös, 2018 ( Coleoptera : Scarabaeidae : Scarabaeinae : Ateuchini ).

In San Esteban Atatlauca (Mixteca region of Oaxaca), G. zempoaltepetlensis was found in pitfall traps baited with human excrement, but also in traps baited with regional fungus, together with Pseudogonaphodiellus zdzislawae Dellacasa, Dellacasa , & Gordon, 2007 ( Coleoptera : Scarabaeidae : Aphodiinae : Aphodiini ), Oscarinus indutilis Harold, 1874 ( Coleoptera : Scarabaeidae : Aphodiinae : Aphodiini ), Blackburneus guatemalensis (Bates, 1887) ( Coleoptera : Scarabaeidae : Aphodiinae : Aphodiini ), and Onthophagus howdenorum Zunino & Halffter, 1988 .

In San José del Pacifico, G. zempoaltepetlensis was collected together with Agrilinellus azteca and Pseudogonaphodiellus zdzislawae . While in San Sebastían Rio Hondo G. zempoaltepetlensis was collected only with Agrilinellus azteca . Both sites are part of the Sierra Sur of Oaxaca.

In Zempoaltépetl, G. zempoaltepetlensis was collected together with Agrilinellus azteca , Gonaphodiellus bimaculosus (Schmidt, 1909) , Gonaphodiellus opisthius (Bates, 1887) , Oscarinus indutilis (Harold, 1874) , Onthophagus chevrolati , O. undulans oaxacanus Zunino & Halffter, 1988 , O. subcancer Howden, 1973 , Onthotrupes viridiobscurus (Jekel, 1865) ( Geotrupidae : Geotrupinae : Geotrupini ), and Ontherus mexicanus Harold, 1868 ( Coleoptera : Scarabaeidae : Scarabaeinae : Dichotomiini).

Discussion. Gonaphodioides zempoaltepetlensis is similar to G. ratcliffei , but can be distinguished from that species mainly by the lateral margin of the pronotum strongly inwardly sinuate before hind angles and by the finer punctation of the interstriae.
