Floromadane pictulus PRENA , sp. n.

Holotype female, Costa Rica , labeled: “ COSTA RICA: Prov. Heredia:/ 10 km SE La Virgen, 450-/ 550m, 10°20'N 84°05'W / 14.- 20.4.2003 / INBio-OET-ALAS transect”, “handcollecting/ leg. Jens Prena ”, “from Psychotria / chitariana ”, INB0003230207 ( INBC), “ HOLOTYPE / Floromadane / pictulus / Prena, 2009”.

Paratypes: 1 male, 2 females. COSTA RICA : Heredia Prov., 10 km SE La Virgen , 450-550 m, 10° 20' N 84° 05' W, 14- 20.4.2003, from Psychotria chitariana, J. Prena, INB 0003230208, female ( JPPC) . PANAMA: Colon Prov., Santa Rita Ridge , 300 m, 10.- 11.6.1977, H. & A. Howden, female ( CMNC) ; Panamá Prov., Cerro Campana , 820 m, 8° 40' N 79° 56' W, 11.6.1995, H. Stockwell, male ( HPSC) .

Description:

Total length 3.7-5.1 mm, standard length 3.6-4.8 mm, width 1.8-2.7 mm; integument brown, appendages reddish brown, yellow scales condensed in dorsolateral pronotal vitta and in variously developed fascia arching from metasternum across elytral callosity to apex ( Fig. 3-4 ), fragmented in Panamanian specimens; pronotal disk slightly arched, punctures confluent, intervals granular, confluent in midline; scutellum square, apex round to acuminate; elytra subtriangular, conjointly rounded and completely covering pygidium, interstriae costate except for flat portions of disk; ventral tooth variously reduced on profemur, largest on mesofemur; pro- and mesotibiae with praemucro distinct, male with sparse fringe of long hairs on ventral edge of protibia; claws separate at base; male genitalia similar to those of F. atrorubens , apex of aedeagus with sides less converging, basal portion of flagellum more narrowly curved, internal sac denticulate.

Plant association:

I collected the holotype and one paratype from foliage of Psychotria chitariana DWYER & HAMMEL (identification confirmed by B. HAMMEL).

Distribution:

The species has been collected at three localities, one in Costa Rica (Atlantic side) and two in Panama, between 300-820 m elevation.

Epithet:

A modified perfect participle derived from Latin pingo, meaning fairly colored.

Note:

The specimens from the three collecting sites show considerable variation in the color pattern; only the two Costa Rican specimens possess completely developed fasciae. Because the only male in the series is atypically small, I selected a fully developed female as holotype.
