( Figures 3, 4 , 10, 14 , 18, 22 , 34, 35, 41 )

Type material. Holotype male ( UVGC) labeled “ HONDURAS, Lempira, P. N. Celaque, Cerro Minas. 2600 m. 01-04 julio 2014. 14° 32´50 N - 88° 40´11 W, V. Sinjaev & M. Márquez ”;; on red paper, “ HOLO- TYPE Chrysina antonkozlovi Monzón ” . Paratypes (16 males and 1 female) with same data as holotype. All paratypes with label, on yellow paper “ PARATYPE Chrysina antonkozlovi Monzón ”. Paratypes deposited in the AOK, EAPZ, FSCA, JMS, KP and ZISP collections.

Description. Holotype male. Length 25.0 mm; width at elytral humeri 10.5 mm; maximum width (middle of elytra) 12.0 mm. Color of dorsum slightly dark yellowish green ( Fig. 3 ); frons lighter yellowish green, clypeus coppery brown; anterior margin of clypeus and fronto-clypeal suture black; ocular canthi reddish golden; antennae reddish brown, scape dorsally greenish gold; pronotal margins greenish gold with reddish reflections; scutellum lateral margins greenish gold; elytral margins reddish gold, humeri and apical umbone yellowish green; pygidium iridescent golden green. Venter shiny yellowish green; sternites with posterior margin reddish gold; tibiae reddish brown; tarsi reddish golden green ( Fig. 4 ). Clypeus ( Fig. 10 ) free margins subtrapezoidal in dorsal view, margined and raised; surface with coarse and dense punctures; frons densely punctuate, punctures dense; fronto-clypeal suture complete; interocular distance 0.8 times wider than antennal club length. Mentum ( Fig. 14 ) small, 1.3 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 setigerous punctures, large narrow horizontal depression close to apex. Pronotum at base 2.7 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 size and depth; intervals convex. Elytron 16.5 mm long and 2.8 times as long as pronotum; lateral margin with bead complete. Pygidium ( Fig. 18 ) moderately punctate, apical margin with long sparse setae; surface moderately convex and slightly prominent towards the apex. Venter with mesometasternal protrusion very short and depressed ( Fig. 22 ). Metasternal sides setigerously punctate, setae long and dense. Legs with protibiae clearly tridentate, apical and medial teeth well developed, third smaller. Genitalia with parameres subsymmmetrical, apex slightly slanted to the left, apically constricted, fused except for very broad “v” shaped, apex bidentate; length of genital capsule 8.0 mm ( Fig. 34, 35 ).

Female. Similar to male except body stout; tarsi less robust and apical sternite not depressed; antennal club short (interocular distance 1.2 times wider than antennal club length). Length 27.5 mm; width at elytral humeri 13.0 mm; maximum width 15.0 mm. Inferior genital plates subsymmetrical; external margin with side pointing spine process and with long fine sparse setae ( Fig. 41 ) (based on female with database label “JMS10798”).

Variation. Males: Length 20.5–25.0 mm; width at elytral humeri 9.5–11 mm; maximum width 10.0– 13.00 mm. Type series very homogeneous yellowish green, two specimens reddish brown with most margins golden green.

Etymology. Named in honor of my friend Anton Olegovich Kozlov from Moscow ( Russia), a great and enthusiastic entomologist that brought this species to my attention.

Diagnosis. This is one of the five green species in the adelaida group in northern Central America (including the two described in this publication). This species seems to be a sister species of C. centralis (Morón) with which it shares many morphological characters. The two can be easily differentiated from the other three green species of the group in the region by having the elytral humeri and umbone yellowish green, very similar to color of disc ( C. pehlkei (Ohaus) , C. hawksi Monzón and C. maishei have golden green elytral humeri and umbone, different from disc). It can be easily separated from C. centralis by the male antennal club, which is longer than the interocular distance, and the different shape of male and female genitalia.

Distribution and remarks. This species is currently known only from the type locality, Celaque National Park, an isolated mountain located south of Santa Rosa de Copán ( Fig. 44 ). It is interesting that even though some collecting has been conducted in the park by several researchers, this species was never collected. It seems to be isolated to the higher altitudes of the park.
