Family Derbidae Spinola, 1839
Subfamily Derbinae Spinola, 1839
Tribe Cenchreini Muir, 1917
Genus: Agoo Bahder and Bartlett 2019
(as subgenus of Omolicna Fennah 1945)
Type species: Omolicna (Agoo) xavieri Bahder & Bartlett, 2019
**Bahder et al. (2020) gave Agoo the new status of a full genus out of Omolicna Fennah, 1945: 440.
Synonyms
None
Distribution
Distribution of Agoo from FLOW (as of 27 Jan 2020)
Nearctic (especially southeast) and Neotropics.
Recognized species
There are 3 species in the genus, so far, all Neotropical.

Economic Importance:
Found on palms including coconut palm, and as such a possible pathogen vector. Unambiguous evidence of pathogen transmission from derbids has not been demonstrated.
Plant associations:
At present, known only from palms (Arecaceae)
Agoo dahliana – Astrocaryum alatum H.F. Loomis (Arecales, Arecaceae) according to Bahder et al. (2020): 531
Agoo xavieri – Coconut palm (Cocos nucifera L.), Arecaceae
Hosts from Bahder et al. 2019, 2020; plant names from USDA PLANTS or Tropicos.

The amended description An amended description from Bahder et al 2019 is as follows
The members of this genus can be separated from similar cenchreine derbids by the relatively broad vertex with pit-like sensoria bordering the lateral margins (these pits were given as a tribal feature in Emeljanov (1995). Vertex wider than long (midline less than 2x as long as broad at widest part), medially concave, with the lateral margins diverging caudally. Frons moderately compressed, elongate, narrowed between eyes, without a longitudinal median carina, lateral margins foliately keeled. A scroll-like extension of the lateral aspect of the pronotum partially surrounds and subtends the base of the antennae forming antennal fossae (a tribal feature). Forewings with pits on postcubitus in clavus (a tribal feature), clavus closed (combined Pcu + A1 reaching CuP), extending beyond midlength of forewing. The male pygofer with a median ventral process, phallotheca (periandrium) with terminal flagellum (endosoma) folded anterodorsally with an asymmetrical arrangement of spines.
The subgenus Agoo is described as follows
Frons narrower and paranota more strongly foliate than subgenus Omolicna. Ventral lobe of pygofer (ventral view) broad, distally attenuating to rounded apex. Aedeagus and endosoma nearly bilaterally symmetrical. Segment 10 elongate, ventrally sinuate (lacking convexity found in most Omolicna s.s.).
Support for the subgenus Agoo is given by the 18S gene, which differs by about 10.6% from O. brunnea, O. triata, and O. joi (which differed from each other by 0.1-0.9%) (Bahder et al. 2019)
Key to the species of Agoo (from an unpublished key)
1. Process present on the dorsal surface of paramere, sclerotized points on parameres; pair of processes on aedeagus situated posterior, wings with distinct black spots … Agoo dahliana
1’. Process absent on the dorsal surface of paramere, sclerotization on parts of parameres
variable … 2
2. Body yellow, wings with stripe on forewing 3
2’. Body Fuscous, wings hyaline … Agoo rubrimarginata
3. The Stripe on forewing terminating in red with the distal black spot; parameres with sclerotized lateral ridge … Agoo sp. n. (ms in prep)
3’. The stripe on forewing fuscous, no sclerotization on parameres … Agoo xavieri
