***Cabera limbata*** is a species of [geometrid](/source/Geometer_moth) [moths](/source/Moth), found in [Guinea](/source/Guinea), [Ghana](/source/Ghana), [Ivory Coast](/source/Ivory_Coast), and [Cameroon](/source/Cameroon) in [West Africa](/source/West_Africa). It belongs to the [monophyletic](/source/Monophyletic_group) *[Cabera subalba group](/source/Cabera_subalba_group).*

## Taxonomy

This moth was previously named *Thysanopyga limbata* (Herbulot, 1954)*.* [1] It was also referred to as *Cabera limbala* in some instances (Scoble, 1999: 98).[2]

## Description

*Cabera limbata* is a medium-sized *[Cabera](/source/Cabera)* species. The length of the [forewing](/source/Forewing) is 12–15 mm (0.47–0.59 in), and is broad and pointed. The [hindwing](/source/Hindwing) resembles the forewing, but with a shorter point at [anal](/source/Anus) angle.

The upperside closely resembles that of *[Cabera toulgoeti](/source/Cabera_toulgoeti)* from [Madagascar](/source/Madagascar). However, it differs on the basis of having smaller discal spots and a darker underside terminal color.

It is the only other moth, except *[Cabera subalba](/source/Cabera_subalba),* that has a single cornutus (spine-like structure) in the vesica. To differentiate between these two species, variations in the [valvae](/source/Clasper) and soccii lobes are considered, as they are much broader and larger in *C. subalba,* respectively. In some cases, differentiation is also done by coloration, as it is paler than *C. subalba,* resulting in the [striations](/source/Striation_(fatigue)) appearing bolder.[3]

## Appearance

Adults feature weakly defined lines along the forewings, along with a median line which is relatively broader. It is undulating and runs just before the discal spot. Forewings contain fine darker grey striations than ground brown colour. Discal spots on the forewing and black, while the ones on hindwing are nearly invisible due to their [ochreous](/source/Ochre) coloration. The underside of the wings is significantly lighter than the upperside, which features a contrasting and well developed darker violet-grey terminal shade along the edges, gradually darkening slightly towards the hindwing. The [cilia](/source/Cilium) and body vestiture are consistent in color with the wings.[3]

### Male genitalia

Adults are distinguished by a lengthy, acutely pointed, and [setose](/source/Seta) [uncus](/source/Lepidoptera_genitalia), a hook-like structure at the terminal end. The [soccii](/source/Soccii) lobes are also setose and prominent, arising from the basal region of uncus. Its [genital capsule](/source/Genital_capsule) is wide and [elliptical](/source/Ellipse), with its 9th [ventral](/source/Anatomical_terms_of_location) segment, or [vinculum](/source/Lepidoptera_genitalia), having a notable median suture. It has a well developed transtilla (band of connective tissue at the base of valvae), with the pair of valvae being broad at their basal two-thirds, featuring a deep indentation ([sacculus](/source/Lepidoptera_genitalia)) that gradually narrows sharply towards the [apex](/source/Lepidoptera_genitalia).

The [dorsal](/source/Anatomical_terms_of_location) margin of the valvae is swollen from the center, and has a middle group of [setae](/source/Seta). The apical margin, whereas, contains multiple groups of stout setae. The inseminating organ, the [aedaegus](/source/Aedeagus), is short and spindle-shaped. The sheath surrounding it or the [vesica](/source/Lepidoptera_genitalia), contains a single nail-like [cornutus](/source/Aedeagus) at its tip.[3]
