V. cubensis (Pfeiffer, 1840)

Veronicellid species can only be reliably distinguished from each other through dissections and observation of the genitalia.
Veronicella aff. floridana: This species may be distinguished from Veronicella cubensis by the genitalia.
V. cubensis: The body color of this slug is variable. There may be multiple shades of brown with two dark stripes running down the length of its back. The lines may be solid or broken up into spots. There may also be an albino form. Another thin, pale white stripe also runs down the midline of the animal. The body texture also varies, where, the body may appear smooth or granular. This slug can usually be distinguished from other species of Veronicellids by the presence its blue-gray eye tentacles. There is also a pale brown area around the eyespots. Adults will measure between 50-70 mm in length, although lengths of up to 120 mm have been recorded.
V. sloanei: Similarly to the other species of this genus, this animal has variable body color, ranging from albino, to tan to grey with varying degrees of grey markings. It has the potential to attain a maximum length of 120 mm. The tentacles of this species are typically blue-grey with pale brown tips.
V. moreleti: This brown-colored species usually does not have a dorso-median stripe. Genitalia: The basal section of the penis is cylindrical. The apex is twisted and the entire region is a hardened mass.

Pest species have been known to consume both ornamental and agricultural crops: melon, pumpkin, pepper, eggplant, cabbage, cassava, taro, sweet potato, yam, papaya, banana, star fruit, mango, noni, citrus and coffee.
Veronicella aff. floridana: This slug is known as a pest of potatoes in Cuba and that of beans, tomatoes and ornamental plants elsewhere.
V. cubensis: This animal is a serious pest of agricultural and ornamental crops (e.g., papaya production in Hawaii) especially in the Pacific Basin. Crops include but are not limited to the following: banana, cabbage, cassava, citrus, coffee, eggplant, mango, noni, papaya, pepper, pumpkin, satar fruit, sweet potato, taro, yam. It can be found in very moist habitats (e.g., near water bodies).
V. sloanei: This opportunistic pest is quite aggressive and consumes a wide variety of ornamental and agricultural crops. Crops consumed by this pest includes but is not limited to the following: leafy vegetables (e.g., spinach, cabbage, lettuce), dasheen, banana, plantain, tannia, papaya, citrus, bean, peanut, Hibiscus sp. and Bougainvillea sp. This pest can also remove the bark of several plants (e.g., Datura sp. and gardenia), therefore girdling the plant. It will lay clutches of 10-12 eggs in a chain.
V. moreleti: This slug has been described from multiple habitats from lowland jungles to open savannas. It is viviparous; therefore, eggs of this species are never intercepted. It has been recorded as a pest of coffee and cacao in Mexico.
