Description. Holotype male. Length 23.5 mm; width at elytral humeri 11.0 mm; maximum width (middle of elytra) 12.0 mm. Dorsum yellowish green ( Fig. 5 ); frons lighter yellowish green, clypeus pinkish brown; ocular canthi greenish gold; antennae reddish brown, scape dorsally pinkish brown with green reflections; pronotal margins brownish gold with green reflections; scutellum yellowish green with brownish reflections; elytral margins greenish brown gold, humeri and apical umbone greenish gold; pygidium iridescent yellowish green with margins greenish gold. Color of venter shiny yellowish green ( Fig. 6 ); sternite and mesosternal margins and suture reddish brown to pinkish brown; anterior femora, protibiae, meso and metatibiae pinkish brownish green; tarsi bluish or greenish silver. Clypeus ( Fig. 11 ) free, margins semicircular in dorsal view, with anterior border straight; margined and raised; surface with coarse and dense punctures. Frons densely punctate, punctures not as dense as in disc; fronto-clypeal suture not obviously complete; interocular distance 1.3 wider than antennal club length. Mentum ( Fig. 15 ) medium, 1.5 times longer than wide; anterior margin depressed and irregular; lateral sides bottle shaped being wider and rounded distally and narrower close to anterior margin; surface with few large punctures. Pronotum at base 2.5 times as wide as interocular distance; surface moderately punctate, punctures small. Lateral margin completely beaded. Elytra punctate striate; striae well defined and with punctures moderate in width and depth; intervals convex. Elytron 16.0 mm in length and 3.2 times as long as pronotum; lateral margin with bead complete. Pygidium ( Fig. 19 ) densely punctate, apical margin with long sparse setae, setae pale reddish yellow; surface moderately convex and slightly prominent towards apex. Venter with mesometasternal protrusion ( Fig. 23 ) medium in length, not extending past mesofemoral base, rounded, slightly depressed. Metasternum sides setigerously punctate, setae long but not very dense. Legs with protibiae clearly tridentate, apical and medial teeth well developed, third smaller. Genitalia with parameres reddish metallic brown, asymmetrical, apex slanted to the left, apically constricted, fused almost completely except for narrow bidentate apex; length of genital capsule 8.0 mm ( Fig. 36, 37 ).

Female. Similar to male except body more stout and averaging longer (to 29.0 mm); tarsi less robust and apical sternite not depressed; antennal club slightly shorter than in males. Inferior genital plates subsymmetrical; apical process expanded and truncate, with long fine sparse setae ( Fig. 42 ).

Variation. Males: length 22.5–27.0 mm; width at elytral humeri 10.0– 12.5 mm; maximum width 10.5–14.00 mm. Females: length 24.0–29.0 mm; width at elytral humeri 11.0–13.0 mm; maximum width 12.5–14.5. Most specimens homogeneous yellowish green, a few slightly darker green, seven males and one female pinkish or reddish brown.

Etymology. We are proud to name this species in honor of the first author’s best friend Maishe Dickman, great insect collector, artist and photographer.

Diagnosis. This is another of the five green species in the adelaida group in northern Central America. Along with C. pehlkei and C. hawksi it can be separated from the others ( Chrysina antonkozlovi and C. centralis ) by having the elytral humeri and umbone golden green, different from the disc. It can be easily separated from C. pehlkei and C. hawksi by the shape of the male genitalia.

Distribution and remarks. This species is currently known from El Güisayote Biological Reserve, an isolated mountain east of Nueva Ocotepeque ( Honduras), very close to the border of El Salvador and Guatemala ( Fig. 44 ). Seemingly identical specimens are also known from: Honduras, La Paz Dept., Reserva Biológica Guajiquiro, Las Trancas, 2170 m, N 14°07´53” W 87°57´47”.
