Diagnosis. Terataki liliputanum can be distinguished from other species in the genus by the presence of microtrichia on antennomeres 4–11 (5–11 in other species); the slightly narrower head; the shape of the porose structure on sternum VII in males (rounded in Te. liliputanum , elongate in other species) and the shape of the paramere that is divided into two lobes near anterior 1/3 of length (paramere almost fully divided in other species).

Description. Body length 13.8–16.2 mm.

Coloration of head and pronotum variable among specimens from metallic green-red to metallic purple. Ventral surface of head and prothorax brown. Antenna orange with antennomeres 1–3 brown. Mesoscutellum dark brownpurple with dark orange border. Elytra variable among specimens, from dark purple-brown with orange margins (majority of specimens) to dark orange. Abdomen dark brown with posterior margin of segment VII and whole segment VIII dark orange. Legs brown, except tarsi dark orange.

Head subquadrate, width: length ratio = 1.02; head hexagonal-trapezoid in shape (but not as wide at temples as other species in the genus). Surface of epicranium with transverse microsculpture, micropunctures and with large punctures scattered throughout head except medially. Antennomeres 1–3 longer than wide; antennomeres 4–5 subquadrate; antennomeres 6–10 transverse; antennomeres 6–8 gradually increasing in width; antennomeres 8–10 similar in size; antennomeres 7–10 asymmetrical (slightly off center; not as pronounced as in the other species). Antennomeres 1–3 with several rows of macrosetae; antennomeres 4–11 with microtrichiae.

Pronotum subquadrate, width: length ratio = 1.06; with transverse microsculpture and rows of micropunctures; large punctures present around margin of pronotum, along the anterolateral corners of pronotum and in two loosely defined sets 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 with faint curved (arch-like) ridge; tergites III–V with anterior basal carina but with no curved ridge. Abdominal tergites with transverse surface microsculpture and with dense punctation; distance between punctures subequal to width of puncture except punctation less dense medially. Sternum with uniform dense punctation, distance between punctures subequal to width of puncture; sternum covered with transverse microsculpture.

Secondary sexual structures. Males with round porose structure ( Fig. 18 ) on sternite VII; posterior border of sternites VI–VII with broad emargination medially; sternite VIII with shallow V-shaped emargination medially; sternite IX with shallow U-shaped emargination medially. Females with no obvious secondary sexual structures. Aedeagus as in Figs. 25–27 ; paramere divided into two lobes on anterior 1/3 of length, lobes together slightly shorter and narrower than median lobe; each lobe converging to pointed apex; in lateral view paramere convex; with sensory spinules as in Fig. 27 . Median lobe in dorsal view wide, converging to rounded apex, with single wide but short dorsal tooth; apex of median lobe without sensory spinules; in lateral view becoming much narrower apically.

Distribution. Known from the states of Espírito Santo, Minas Gerais and Rio de Janeiro in Brazil.

Habitat. Unknown.

Remarks. The species epithet was changed from liliputana to liliputanum to match the gender of the genus. A specimen in BMNH is labeled as Trigonopselaphus arrowi Type Bernh. This is a manuscript name and this specimen is conspecific with Te. liliputanum . The specimen is slightly longer and with darker coloration than the type of Te. liliputanum but all other morphological features (including the aedeagus) are identical.
