Cynorta
Cynorta is a genus of harvestmen (Opiliones) in the family Cosmetidae, subfamily Cynortinae. It was first described by Carl Ludwig Koch in 1839. The type species is Cynorta conspersa. The genus is currently considered poorly defined, with species from disparate regions included without demonstrated shared ancestry.
Cynortoides
Cynortoides is a genus of harvestmen (order Opiliones, family Cosmetidae) described by Roewer in 1912. It belongs to the subfamily Cynortinae within the diverse neotropical harvestman fauna. Species in this genus are characterized by features typical of cosmetid harvestmen, including relatively compact bodies and often ornate dorsal armature. The genus occurs in Central and South American regions.
Cynortoides quadrispinosa
Cynortoides quadrispinosa is a species of harvestman (Opiliones: Cosmetidae) described by Goodnight & Goodnight in 1942. It belongs to the family Cosmetidae, a diverse group of neotropical harvestmen characterized by often ornate body armature. The specific epithet 'quadrispinosa' suggests the presence of four spines, likely on the dorsal scutum or abdomen. The species has been documented in citizen science observations, indicating it is not exceptionally rare in suitable habitat.
Erginulus
Erginulus is a genus of harvestmen in the family Cosmetidae, described by Roewer in 1912 with the type species Erginus serratipes. The genus comprises 29 described species distributed primarily in eastern Mexico and northern Central America, with a few outlying records. Species are medium to large-sized cosmetid harvestmen, with Erginulus clavotibialis in Belize reaching 6–7.5 mm adult body length. Males exhibit sexual dimorphism with two distinct morphotypes (α and β males), characterized by enlarged chelicerae and armed leg IV with protuberances or spines; females have smaller chelicerae and unarmed legs.
Erginulus subserialis
Erginulus subserialis is a harvestman (order Opiliones) in the family Cosmetidae, originally described by Pickard-Cambridge in 1905. The species belongs to the subfamily Metergininae, a group of tropical harvestmen characterized by often ornate dorsal ornamentation. It is one of several species in the genus Erginulus, which is distributed across Central and South America. The species has been documented through iNaturalist observations, indicating ongoing contemporary study.
Libitioides sayi
Say's Armored Harvestman
Libitioides sayi is a species of harvestman (order Opiliones) in the family Cosmetidae, commonly known as Say's Armored Harvestman. It was described by Simon in 1879. As a member of the Laniatores suborder, it possesses raptorial pedipalps adapted for predation. The genus Libitioides belongs to the diverse Neotropical harvestman fauna.
