description: Ceratalictus ischnotes (Vachal, 1911)
(Figs. 12, 20, 40)
Halictus ischnotes Vachal, 1911: 20. Lectotype female (MNHP) (examined). Ceratalictus ischnotes; Moure & Hurd, 1987: 246
Diagnosis. Body with bluish coloration, lateral angle of pronotum strongly acute, projected (Fig. 20); preoccipital ridge strongly produced, almost forming a lamella; mesoscutal disc with punctures irregularly spaced (1-3 puncture diameters), surface between punctures micro-reticulate (Fig. 20).
Description. Female. Head. As wide as long. Labrum. Basal elevation very short and restricted to apical portion. Clypeus. Punctures irregular in size and spacing, smaller and closer (1–2 puncture diameters) at margins of clypeus compared to centre; one-third distal with punctures slightly elongate, surface without micro-reticulation, bright. Supraclypeal area. Punctures of variable size, few punctures centrally, becoming more densely punctured laterally (1–2 puncture diameters), surface slightly micro-reticulate with bright appearance. Lower parocular area. Punctures coarse and contiguous, surface between punctures weakly roughened, without micro-reticulation. Upper parocular area and frons. Closely punctuate especially on frons, surface rugulose near antennal alveolus. Preoccipital ridge. Strongly produced, curved upward almost forming a lamella. Mesosoma. Pronotum. Lateral angle strongly acute, projected. Mesoscutum. Disc with punctures irregularly spaced (1-3 puncture diameters), leaving small impunctate areas, closely punctate laterally, surface of disc strongly micro-reticulate. Mesoscutellum. Punctures contiguous, finer than those of mesoscutum, surface between punctures weakly micro-reticulate with bright appearance, surface slightly roughened. Metapostnotum. About 1.5x length of metanotum, weakly concave with apex not acuminate, posterior margin rounded with lateral margins straight; metapostnotal carinae almost straight. Lateral surface of propodeum. Punctures fine, surface slightly roughened, without scattered large punctures, micro-reticulation not evident. Posterior surface of propodeum. Punctures oblique, with some coarser punctures intermixed, surface with rugulose appearance on lower part. Metasoma. T1. Disc punctures fine, separated by more than 3 puncture diameters, surface smooth and bright. T2. Disc punctures fine, separated by 3 puncture diameters, surface smooth and bright. Body color. Apical half of clypeus black; body with blue reflections, metasoma brown with blue metallic highlights; legs light brown without metallic highlights; body setae white, except for face and mesosoma setae yellow on dorsal part, tibia and tarsi setae light yellow; T5 setae light brown. Measurements. Abl: 4; mwl: 4.1; mhw: 1.5; mhl: 1.2; mmw: 1.0.
Male unknown.
