Colliuris tetrastigma ( Chaudoir, 1863)

Type material. Chaudoir original description of this species was based on a single specimen. I have not seen the holotype which should be in MHNP.

Description. Smaller than C. lioptera with the elytra proportionally shorter. COLOR. Body more or less uniformly dark reddish-brown to almost black dorsally, elytron with preapical, pale spot on intervals 5–8 or 6–8 and another one in front of middle on intervals 4–7 or 5–7 (in some specimens restricted to interval 6); antennomeres 1 and 2 reddish-brown to brown dorsally, antennomeres 3 and 4 paler, reddish-yellow, antennomeres 5–7 and 10–11 (except extreme base of antennomere 10 in some specimens) brown to dark reddish-brown, antennomeres 8–9 whitish; femur yellow at base (anterior leg) to basal half (posterior leg), brown on apical half or more, tibia brown with whitish band at or near middle. MICROSCULPTURE. Body without meshes or microlines dorsally. HEAD. Eye large, protruding. Posterior supraorbital seta located at about level of posterior edge of eye. PROTHORAX. Pronotum without distinct transverse wrinkles; side with one seta. Tergosternal suture less defined than in C. lioptera particularly in posterior half where it is indistinct in many specimens. ELYTRA. Interval 3 with 8–14 discal setae, interval 5 with 3–10 discal setae, interval 7 without or with one or two discal setae; setae proportionally longer than in C. lioptera . Strial punctures moderately coarse on intervals 3–6 on basal half, fine to indistinct on remaining striae. Interval 3, or 3 and 4, with shallow depression before middle of elytra; intervals 7 and 8 with preapical swelling more prominent than in C. lioptera . ABDOMEN. Sterna with sparse pubescence. MALE GENITALIA. Median lobe as illustrated ( Fig. 10 ).

Body length: 6.5–8.6 mm.

Geographical distribution. This species is found in Jamaica and on the continent from Nayarit and Veracruz-Llave south to Chiapas and Belize ( Fig. 22 ).
