Aegomorphus doctus (Bates, 1880) View in CoL ( Fig. 2 View Figure 2 C-2F)

Acanthoderes doctus Bates, 1880b: 141 View in CoL .

Bates (1880b) described Acanthoderes doctus View in CoL based on a single female from Mexico (Oaxaca) as follows (translated):“Elongate,convex, dark gray, elytra black punctate, with grayish band before middle, M-shaped black band after middle, and A-shaped black band near apex; antennae and legs dark reddish, ringed with dark flesh-colored bands, those bands linear in the apical segments; frons wide, flat, expanded toward anterior region; vertex with two black macula; thorax with large tubercles laterally and dorsally (their apices very acute); sides of prothorax coarsely punctate until coxae; elytral apex short, transversely sinuous-truncate; elytra with obtuse carina, arched and elevated basally, punctures sparse, with black setae, basally tuberculate; mesoventral process bituberculate; legs with long setae. Length 18 mm. Female.”

As usual in species of this genus, Aegomorphus doctus has a great morphological variation, which is possible to see by comparing a specimen from Mexico (Jalisco) ( Fig. 2C View Figure 2 ), with the holotype ( Fig. 2G View Figure 2 ), and a specimen photographed by Jesus Santiago Moure in the 1970s ( Fig. 2H View Figure 2 ). Comparing those three specimens we can list the following variations:

1. Black longitudinal band on each side of the pronotum not reaching posterior margin ( Fig. 2C View Figure 2 ) (or reaching, Fig. 2 View Figure 2 G-2H);

2. Small yellowish-white pubescent macula close to black longitudinal band on each side of the pronotum present ( Fig. 2C View Figure 2 ) (absent, Fig. 2 View Figure 2 G-2H);

3. Large oblique pubescent band on anterior half of the elytra well-defined and grayish-white and not partially surrounded by yellow pubescence ( Fig. 2 View Figure 2 G-2H) (fragmented, whitish, and partially surrounded by yellow pubescence, Fig. 1C View Figure 1 );

4. Black pubescent macula close to superior margin of the oblique grayish-white pubescent band proportionally slender ( Fig. 2 View Figure 2 G-2H) (proportionally wide, Fig. 2C View Figure 2 );

5. Elytra with subtriangular black pubescent macula near scutellum ( Fig. 2C View Figure 2 ) (almost absent, Fig. 2 View Figure 2 G-2H);

6. Elytra with narrow, inverted L-shaped white pubescent band on anterior third, surrounded by yellow pubescence ( Fig. 2C View Figure 2 ) (absent, Fig. 2 View Figure 2 G-2H);

7. Zigzag black pubescent band of the holotype (M-shaped according to Bates) entire ( Fig. 2G View Figure 2 ), fragmented ( Fig. 2C View Figure 2 ), or V-shaped ( Fig. 2H View Figure 2 );

8. Inverted V-shaped black pubescent macula near apex of the elytra (A-shaped according to Bates) absent ( Fig. 2H View Figure 2 ) or present ( Fig. 2G View Figure 2 ), or fragmented ( Fig. 2C View Figure 2 );

9. Elytral carinae present but slightly distinct ( Fig. 2C View Figure 2 ) or more distinct ( Fig. 2 View Figure 2 G-2H).

Aegomorphus doctus View in CoL can be recognized by the wide frons expanded toward clypeus, antennomeres V and VI biannulate on anterior half, and presence of zigzag black pubescent band after middle of the elytra. Currently, the species is known from Mexico (Oaxaca) ( Monné, 2021; Tavakilian & Chevillotte, 2021).
