Type material. Lectotype for C. badiipennis , here designated: male, with labels as follows: “ 5977” / “ Type ” / “ Lectotype Creophilus badiipennis Nordmann des. Chatzimanolis 2013” / “ Terataki badiipennis (Nordmann, 1837) det. Chatzimanolis 2013” (ZMHB). Nordmann (1837) stated in the original description that the type locality is Brazil.

Holotype for Trigonopselaphus nobilis : male with labels as follows: “♂” / [black round label] / “Matto Grosso” / “ Trigonopselaphus nobilis n. sp. Wendeler det.” / “ Holotypus ” / “ Terataki nobilis (Wendeler, 1956) det. Chatzimanolis 2013” (ZMHB). Paratype: female with labels as follows: “♀” / “Matto Grosso” / “ Trigonopselaphus nobilis n. sp. Wendeler det.” / “ Paratypus ” / “ Terataki nobilis (Wendeler, 1956) det. Chatzimanolis 2013” (ZMHB). Wendeler (1956) stated that he had one male and two female specimens, however, only one male and one female specimen were found in ZMHB.

Diagnosis. Terataki badiipennis can be distinguished from all other species in the genus by the following characters: color of head, pronotum and abdomen bright metallic green with bright light brown-orange elytra (other species in Terataki with metallic green head and pronotum typically have purple or green elytra; if elytra brownorange, then abdomen brown or black). Additionally, the paramere of the aedeagus lacks sensory spinules (sensory spinules present in other species).

Description. Body length 13.1–16.2 mm.

Coloration of head and pronotum bright metallic green with dark purple overtones. Ventral surface of head and prothorax metallic dark green-purple. Antenna reddish brown with antennomeres 1–3 metallic green-brown. Mesoscutellum dark metallic green-purple with orange border. Elytra bright light brown-orange. Abdomen dark metallic green with posterior margin of tergum III, IV and VIII orange; with two bright orange dots on anterolateral corners of sternum VIII. Legs dark metallic green-purple, except tarsi light brown.

Head slightly transverse, width: length ratio = 1.29; head hexagonal in shape, widest at temples. Surface of epicranium with polygon-shaped microsculpture, micropunctures and with medium-sized punctures scattered throughout except medially. Antennomeres 1–3 longer than wide; antennomeres 4–5 subquadrate; antennomeres 6–10 transverse; antennomere 5–7 gradually increasing in width; antennomere 8 slightly shorter than antennomere 7; antennomeres 8–10 similar in size; antennomeres 7–10 asymmetrical (slightly off center; Fig. 16 ). Antennomeres 1–4 with several rows of macrosetae; antennomeres 5–11 with microtrichiae.

Pronotum subquadrate, width: length ratio = 1.08; with polygon-shaped microsculpture and rows of micropunctures; medium-sized punctures present around margin of the pronotum and in two loosely defined set of rows on each half of pronotum, one set of rows around midline and another approximately halfway between midline and lateral margin; each row with multiple punctures; distance between punctures in each row varies. Mesoscutellum with polygon-shaped microsculpture and large almost confluent punctures.

Elytra subequal in length to pronotum with small dense uniform punctation; distance between punctures subequal to 1.5 times width of punctures; elytra with dense polygon-shaped microsculpture.

Abdomen. Tergite II without curved (arch-like) ridge; tergites III–V with anterior basal carina but with no curved ridge. Abdominal tergites with dense transverse surface microsculpture and micropunctures; with dense punctation; distance between punctures subequal to width of puncture except punctation less dense medially; punctures transversely elongate on tergites IV–VII. Sternum with uniform dense punctation, distance between punctures subequal to width of puncture; sternum covered with dense transverse microsculpture.

Secondary sexual structures. Males with transversely elongate porose structure ( Fig. 19 ) on sternite VII; posterior border of sternites VI–VII with broad emargination medially, emargination deeper on VII than on VI; sternite VIII with moderate broad V-shaped emargination medially; sternite IX with shallow U-shaped emargination medially. Females with no obvious secondary sexual structures.

Aedeagus as in Figs. 20–21 ; paramere divided to near base into two lobes, lobes together slightly shorter and narrower than median lobe; in dorsal view distance between two lobes wider apically; each lobe converging to rounded apex; in lateral view paramere convex; without sensory spinules. Median lobe in dorsal view wide, converging to emarginate apex, with single wide dorsal tooth; anterior third of median lobe appears darker and slightly elevated; apex of median lobe without sensory spinules; in lateral view becoming much narrower near apex.

Distribution. Known from Central, Paraguari, and Presidente Hayes departments in Paraguay and from the states of Mato Grosso and Minas Gerais in Brazil.

Habitat. Unknown, some specimens were collected in “soil traps”, which probably refers to pitfall traps.
