Colliuris portoricensis Liebke, 1930

Colliuris portoricensis Liebke, 1930: 688 . Type locality: «Portorico» (original citation).

Type material. Liebke described C. portoricensis from two specimens in "Zoolog. Museum Berlin". I have seen both specimens, housed in MNHU, which are females. One of them is here designated as the lectotype. It is labelled "Portorico Krug S.G./ 349. Casnonia insignis Chaud. [handwritten]/ Type [handwritten on a rectangular red label]/ C. portoricensis Liebke [handwritten]"/ Lectotype Colliuris portoricensis Liebke Des. Y. Bousquet'03".

Description. COLOR. Body black dorsally though apical half of elytra slightly paler, dark reddish-brown, elytron with small, preapical, pale spot on intervals 6 and 7, or 5–7, and small spot on interval 6 or 5 and 6 before middle of elytra in most specimens, one or both spots indistinct in some specimens; antennomere 1 brown dorsally, antennomere 2 yellow to brown, antennomere 3 yellow, antennomere 4 yellow with apical half infuscate, antennomeres 5–11 brown to dark reddish-brown though last ones slightly paler than preceding ones in many specimens; femur yellow at base (anterior leg) to basal half (posterior leg), reddish-brown on apical half or more, tibia yellowish-brown to pale reddish-brown with both extremities more or less infuscate, without whitish submedian band. MICROSCULPTURE. Body without meshes or microlines dorsally. HEAD. Posterior supraorbital seta located at about level of posterior edge of eye. PROTHORAX. Pronotum with transverse wrinkles; side with one seta. Tergosternal suture distinct over entire length of pronotum. ELYTRA. Interval 3 with 15–23 discal setae, interval 5 with 12–16 discal setae, interval 7 without setae. Strial punctures rather coarse on anterior half, very fine and distant on posterior half. Interval 3 with longitudinal depression before middle of elytra; intervals 7 and 8 with preapical swelling. Posterolateral angle more acutely projected posteriad than in other species of the group. ABDOMEN. Sterna with sparse pubescence. MALE GENITALIA. Median lobe very characteristic ( Fig. 11 ).

Body length: 8.3–9.8 mm.

Geographical distribution. This species is known from Puerto Rico, Dominican Republic and Haiti.

Note. This species was placed in the subgenus Odacanthella Liebke by Liebke (1930: 661) and later ( Liebke 1938: 56) in the subgenus Calocolliuris Liebke. In my opinion it is related to the species of the tetrastigma group.

NOAH GROUP

Diagnostic description. Body without pubescence dorsally. HEAD. Vertex short. Posterior supraorbital seta located slightly in front of posterior edge of eye. PROTHORAX. Pronotum without punctures, with faint transverse wrinkles, without dorsal swelling; lateral groove indistinct; side with one seta. Proepisternum without punctures except at extreme base; prosternum without punctures. ELYTRA. Lateral edge extended anteriad humerus. Discal setae not black and not stiff. Interval 3 with four or five discal setae; interval 5 with two or three discal setae, interval 7 without or with one discal seta. ABDOMEN. Sterna without pubescence; last sternum of male with median notch along apical edge.

Note. Darlington (1934: 124) noted that C. noah “has no really close relatives.” Among the species I have seen, I am unable to place any other ones in the same group as C. noah .
