Colliuris sulcicauda ( Bates, 1883)

Casnonia sulcicauda Bates, 1883: 162 . Type locality: «San Gerónimo [= San Jerónimo, Baja Verapaz], Guatemala » (original citation).

Type material. Bates described this species from an unspecified number of specimens. The BMNH contains one syntype, a female, which is here designated as the lectotype. It is labelled: " Type H.T. [small round with red trim label]/ S. Geronimo, Guatemala. Champion./ B.C.A. Col. I.1. Casnonia sulcicauda, Bates. / Lectotype Ψ Casnonia sulcicauda Bts By Erwin '76 [partly handwritten]".

Description. COLOR. Head and pronotum black with greenish lustre, elytra black with greenish lustre over extreme base and humeral regions only, with median, transverse, pale band reaching from lateral margin to about middle of elytron and irregular, apical, transverse, pale band reaching from lateral margin to suture. Antennomere 1 brown, antennomeres 2–4 paler, brownish-yellow, antennomeres 5–11 brown to reddishbrown. Femur yellow on basal half or basal two-thirds, apical half or less brown to reddish-brown; tibia brownish-yellow to yellowish-brown. MICROSCULPTURE. Frons and vertex without distinct meshes. Pronotum without distinct meshes though spots of faint transverse meshes can be seen on most specimens. Proepisternum and prosternum without meshes. Elytra with granulate microsculpture (meshes irregularly isodiametric and sculpticells convex) over pale apical band, without meshes on remaining surface including median pale band. PROTHORAX. Pronotum with five to eight setae on each side. Proepisternum and prosternum without distinct wrinkles. ELYTRA. Intervals 1, 3 and 5 with 10–14 discal setae, interval 7 with six to ten discal setae. Striae impunctate, poorly impressed on disc, more so laterally and over pale apical band. MALE GENITALIA. Median lobe very similar to that of C. marginestriata ( Fig. 5 ).

Body length: 6.5–7.2 mm.

Geographical distribution. I have seen only a few specimens of this species collected in southern Mexico ( Fig. 26 ) and Guatemala.

Records. Mexico. CHIAPAS. San Quintin (700') 5–20.II.1966, G.E. Ball & D.R. Whitehead (1ɗ, UASM) [air-strip/savanna]. 7.7 mi. N Frontera Comalapa (2600'), 15–16.VI.1966, G.E. Ball & D.R. Whitehead (1ɗ, UASM). QUINTANA ROO. 34 mi. W Chetumal nr. Kohunlich Ruins, 27–28.VII.1980, Schaffner, Weaver, Friedlander (1ɗ, TAMU).

Note. Colliuris sulcicauda (Bates) was placed by Liebke (1938: 61) in the subgenus Pseudocasnonia Liebke, 1930 (type species: C. leprieuri Laporte ) along with C. affinis Chaudoir (Amazonia) , C. bucephala Liebke ( Bolivia; Paraguay), C. leprieuri Laporte (French Guyana), C. olivacea Chaudoir (Amazonia) , C. punctatostriata Chaudoir ( Paraguay; French Guyana), C. signata Chaudoir ( Brazil) , and C. viridicollis Chaudoir ( Colombia) . I have seen two specimens determined as C. leprieuri by Liebke (SMTD) from Cayenne and Paraguay and they belong in my opinion to the bivittis group.
