Cynortoides quadrispinosa

The combination of four dorsal spines (as indicated by the specific epithet), dorsoventrally flattened body form, and membership in Cosmetidae distinguishes this species. It can be separated from congeners by the specific number and arrangement of spines, though detailed comparative descriptions of Cynortoides species are limited in available literature. The family Cosmetidae is recognizable by the fused coxae of legs II-IV and often elaborate dorsal ornamentation. Microscopic examination of genitalia and pedipalps is typically required for definitive species identification in this genus.

As a member of Cosmetidae, the body is likely dorsoventrally flattened with a well-developed scutum covering most of the dorsal surface. The specific epithet 'quadrispinosa' indicates four prominent spines, probably arranged on the scutum or free tergites. Coloration and patterning typical of the genus likely includes contrasting light and dark markings. Legs are long and slender relative to body size, as is common in the family. Sexual dimorphism in spine development may occur, with males often bearing more pronounced armature.

Neotropical region; specific range details are poorly documented in available sources. The genus Cynortoides occurs in Central and South America, and C. quadrispinosa likely follows this general pattern. Citizen science observations suggest presence in suitable mesic habitats within this broad region.

• Other Cynortoides speciesCongeneric species share the general body plan and may differ primarily in spine number, arrangement, and pattern; C. quadrispinosa is distinguished by the four-spine condition referenced in its name.
• Other Cosmetidae generaMembers of this family share dorsoventral flattening and often elaborate ornamentation; genus-level identification requires examination of pedipalp and genital morphology.
