Stenolis Bates, 1864

Stenolis Bates, 1864: 149 ; Monné, 2005: 127 (cat.).

Type-species: Stenolis undulata Bates, 1864 by monotypy [= Stenocorus angulatus Fabricius, 1801 ].

Redescription. Body elongate, slightly convex. Upper lobes of eyes separated by about twice width of a lobe; lower lobes usually twice as tall as genae below them. Antennae with 11 antennomeres, at least twice length of body. Ventral surface of antennomeres III–IV with few scattered short setae. Prothorax with or without minute obtuse lateral tubercles in beginning of posterior third; pronotum without prominences. Elytra without setae, centro-basal crista, or carinae; apices rounded, truncate, or emarginate. Prosternal process less than one-third width of a procoxa; mesosternal process as wide as a mesocoxa. Metatarsomere I as long as II+III, or slightly longer.

Comments. Bates (1864) proposed Stenolis based on one species, S. undulata , and commented on the similarity to some species of Nyssodrys (today Nyssodrysternum Gilmour, 1960 ) and Lepturges Bates, 1863 , but noted differences in the last abdominal segment and in the shape of the prothorax.

Stenolis shares with Toronaeus Bates, 1864 and Neseuterpia Villiers, 1980 , elytra without setae, centro-basal crista or carinae, and a prothorax without lateral tubercles. In Stenolis the sides of the prothorax are unarmed or have a minute tubercle on the posterior third. Stenolis differs from Toronaeus by the short ovipositor and the basal metatarsomere equal to or slightly longer than the following two segments of the tarsomere together. In Toronaeus the ovipositor is elongated and the basal metatarsomere is longer than the following two segments of the tarsomere together. Stenolis differs from Neseuterpia by the prothorax narrowed anteriorly and posteriorly, by the straight rather than curved protibiae, and males with femorae pedunculate-clavate. In Stenolis the prothorax is always widest behind the middle, and the femorae and tibiae are straight in both sexes.
