Colliuris pilatei (Chaudoir, 1848)

Type material. Chaudoir described this species from two specimens collected by Pilate in Yucatán, Mexico. I have not seen these specimens, which should be located in MHNP.

Description. COLOR. Head and pronotum dark reddish-brown to black with greenish lustre in most specimens, elytra yellowish with reddish-brown markings including base (entirely or around scutellum only), intervals 1–3 or 1–4 on anterior half, intervals 1–6 or 1–7 behind middle, then narrowed to include intervals 1–3 or 1–4, then intervals 4–6 or 4–7 before apex; antennomere 1 pale reddish-brown above, yellow beneath, antennomere 2 pale yellow with base infuscate in most specimens, antennomere 3 pale yellow, antennomere 4 pale yellow with apex or apical half slightly infuscate, antennomeres 5–11 reddish-brown; femur yellow with apex infuscate, tibia yellow with base, in some specimens also apex, slightly and narrowly infuscate. MIC ROSCULPTURE. Frons and vertex with poorly impressed meshes. Pronotum without meshes. Proepisternum with markedly transverse meshes. Elytra with poorly impressed, isodiametric meshes on lateral intervals, without distinct meshes on medial intervals. PROTHORAX. Pronotum without lateral dentiform projection along anterior edge. ELYTRA. Striae impressed to apex though very finely so in anterior half on medial striae; strial punctures moderately coarse on anterior half, becoming finer toward apex. MALE GENITALIA. Median lobe as illustrated (Fig. 8).

Body length: 6.0– 7.8 mm.

Geographical distribution. This species ranges from southern Arizona to northwestern Costa Rica (Guanacaste Province) (Fig. 17).

Habitat. Based on associated labels, several specimens seen were collected "in bromeliads."

Note. The original description by Chaudoir matches the character states of this species. Chaudoir thought that his specimens could be the same as those of C. fusca Reiche, a species occurring in Colombia and Argentina. The reader is referred to Liebke (1938: 57) for character states separating the two species.

Chaudoir (1848: 47) originally used the spelling pilati for this species name. However, the incorrect subsequent spelling pilatei introduced by Chaudoir (1863: 289) himself is in prevailing usage and attributed to the publication of the original spelling. Consequently, this spelling is deemed to be the correct original spelling and is to be preserved (ICZN 1999, Art. 33.3.1).

Diagnostic description. Body without pubescence dorsally. HEAD. Vertex moderately long to long. Posterior supraorbital seta located behind level of posterior edge of eye. PROTHORAX. Pronotum with punctures restricted to anterior and/or posterior margins, without conspicuous transverse wrinkles or dorsal swelling; lateral groove distinct; side with four or more setae. Proepisternum with coarse punctures at least over posterior half; prosternum without punctures, except in front of prosternal apophysis and near apex. ELYTRA. Lateral edge extended anteriad humerus. Discal setae not black, not stiff. Intervals 3, 5 and 7 with numerous setae. ABDOMEN. Sterna without pubescence, except for minute setae medioapically on last sternum of female; last sternum of male with median notch along apical edge.

Note. Liebke (1938: 54) included in his subgenus Odacanthella, besides C. pensylvanica and C. picta, also C. geniculata Gory from Brazil. I have not seen specimens of that species. Liebke (1938: 55) placed C.

yucatana Liebke, considered in the present work a junior synonym of C. pensylvanica, in his subgenus Casnoniella Liebke, 1938 (type species: Casnonia peruana Erichson, 1847). Until specimens of C. peruana Erichson from Peru can be studied, I feel it is premature to list Casnoniella as a synonym of Cosnania Dejean.

Liebke (1938: 54) provisionally listed in this subgenus the following species: C. limbata Waterhouse (here regarded as a synonym of C. pensylvanica), C. lengi Schaeffer, C. sulcicollis Bates, C. strasseni Liebke (Paraguay), C. lioptera Bates, C. tetrastigma Chaudoir, C. humboldti Liebke (Brazil, Paraguay), C. emdeni Liebke (Peru), C. cyanella Liebke (Amazones), C. cyanescens Chaudoir (Amazones), and C. quadrimaculata Gory (Cayenne) . I have seen specimens of C. lengi, C. sulcicollis, C. lioptera, C. tetrastigma, and C. emdeni . The first two species belong to this group, while the other three belong to the tetrastigma group.
