Tingis yamaboushi

Diagnosis. Recognized among other species of Tropidocheila by a combination of the following characters: general color brown (Fig. 1 C – G); pubescence on dorsum shorter than diameter of compound eye; head with four spines (Fig. 4 C); a pair of frontal spines reaching beyond tip of clypeus; a pair of occipital spines reaching middle part of compound eye; rostrum reaching posterior margin of metasternum (Fig. 2 D); anterior margin of hood curved inward throughout its length; lateral carinae of pronotum indistinct on pronotal disc; paranotum ridge-shaped, subvertical, with 2 rows of areolae in anterior part and a single row in middle part, without areolae in posterior part (Fig. 2 E); costal area of hemelytron with 2 rows of areolae throughout its length, narrower than subcostal area at widest part of each (Fig. 2 F); subcostal area with 4 rows of areolae at widest part; discoidal area with 9 – 10 rows of areolae at widest part; and sutural area with 13 – 14 rows of areolae at widest part. Tingis (Tropidocheila) yamaboushi sp. nov. resembles T. (Tr.) matsumurai in general appearance, although the former can be easily distinguished from the latter based on the following characteristics: general color brown (Fig. 1 C – G); head with four spines (Fig. 4 C); rostrum reaching posterior margin of metasternum (Fig. 2 D); anterior margin of hood curved inward throughout its length; lateral carinae of pronotum indistinct on pronotal disc; paranotum with 2 rows of areolae in anterior part and a single row in middle part, without areolae in posterior part (Fig. 2 E); subcostal area of hemelytron with 4 rows of areolae at widest part (Fig. 2 F); and sutural area with 13 – 14 rows of areolae at widest part. In contrast, T. (Tr.) matsumurai presents the following characteristics: general color black (Fig. 1 A); head with five spines (Fig. 4 A); rostrum reaching middle of metasternum (Fig. 2 A); anterior margin of hood curved outward throughout its length; lateral carinae of pronotum distinct on pronotal disc; paranotum with a single row of areolae in anterior half, without areolae in posterior half (Fig. 2 B); subcostal area of hemelytron with 3 rows of areolae at widest part (Fig. 2 C); and sutural area with 11 – 12 rows of areolae at widest part.
