Tico Bahder & Bartlett 2021

Genus Tico Bahder & Bartlett 2021a

Type species: Tico emmettcarri Bahder & Bartlett 2021a, by original designation.

Amended Diagnosis. Small (~2.5–3.0 mm), cenchreine derbids. Frons moderately compressed (length at midline about 4x dorsal width), median carina absent, lateral carinae foliately keeled, bearing a row of sensory pustules. Vertex roughly triangular or trapezoidal, widest posteriorly, disc concave, lateral margins keeled (bearing pustules), with transverse carinae near fastigium. Forewing with ScP branch preceding apex of clavus (resulting in a long marginal cell; this cell short in Cenchrea dorsalis). Pygofer opening with distinct lateral expansions (not processes, viz. Cenchrea in Fennah 1952 figs 10A, E), medioventral margin of opening without lobe. Gonostyli long and spatulate, apex rounded, with a medially directed dorsal lobe near midlength. Aedeagus nearly bilaterally symmetrical, lacking projections on shaft, except apically, terminating in retrorse endosoma and complex array of processes. Anal tube elongate, in lateral view ventral margin weakly concave, apex inflected downward, apex truncate; in dorsal view broadly spatulate.

Distribution. Costa Rica, Trinidad, Venezuela (Fennah 1952, Bahder et al. 2021a).

Plant associations. Asplundia sp. (Cyclanthaceae).

Key to the species of Tico

2. Forewing with a black spot at base (in clavus) and 4 large blacks spots distally along trailing margin (dorsal portion of wing when in repose; Bahder et al. 2021a fig. 14, Fennah 1952 fig 11G); head with dark marking anterior to eyes (Bahder et al. 2021a fig. 13C)............................................................................................ 3

-. Forewing without a black spot in clavus or series of 4 dark spots along trailing margin, markings limited to well-separated single spots (including one in costal cell, one near fork of CuA, and one in cell C3, proximad of an intramedial crossvein; head in front of eyes pale........................................................................ T. emmettcarri

3. Ventral processes of first gonapophysis of ovipositor not twisted (Fennah 1952 fig 11H), apex of the dorsal process angled dorsad, bifid; pregenital plate pyramid-shaped (Fennah 1952 fig 11K).................................... T. sororius

-. Ventral processes of first gonapophysis twisted into near-helix (Bahder et al. 2021a, fig. 19B), apex of the dorsal process not bifid, hooked anteriorly; pregenital plate spade-shaped (Bahder et al. 2021a, fig. 19A)................. T. pseudosororius
