Trigona perilampoides Cresson, 1878: 181 [lectotype: ANSP 2175; worker, Mexico] new lectotype designation
Diagnosis. The worker of this species is similar to that of N. camargoi. In addition to the brownish wings (light reddish brown with dark grayish brown apex in N. camargoi), it can be distinguished from that species by the shallower median emargination of the mesoscutellum (3.8 times broader than long in N. perilampoides, 1.8 times broader than long in N. camargoi).
Redescription. Lectotype worker: Total body length 4.40 mm; head width 1.92 mm; maximum width of mesoscutum 1.39 mm; forewing length (including tegula) 4.5 mm. Head 1.2 times wider than long; malar area about 0.7 times width of F3; clypeus about 1.8 times broader than long; intertorular distance 1.2 times torular diameter; torulorbital distance 1.8 times torular diameter; interocellar distance 2.5 times OD, 1.1 times longer than ocellocular distance; ocelloccipital distance 2.3 long as OD; scape 6.0 times longer than wide, 0.8 times width of F3; flagellomeres as broad as long, except apical flagellomere longer than broad. Mesoscutellum 1.6 times broader than long, basal fovea V-shaped, slightly longer than broad, posterior margin with median semicircular emargination, about 3.8 times broader than long, tooth lateral to emargination right-angled. Measurements of other structures in Table 2.
Color black, except as follows: reddish brown on apical two-thirds of mandible and flagellum; dark reddish brown on antennal scape; bright yellow on lateral margin of mesoscutum, axilla, lateral tooth of posterior margin of mesoscutellum, outer surfaces of mesotibiae basally, posterior margin of metatibia, except apical half; brown on distitarsi and anterior and posterior margins of metabasitarsus. Wing membrane, veins and pterostigma brown, marginal cell darker.
Pubescence pale yellow, except minutely branched, appressed setae on head and mesosoma whitish; orange on metatibia. Antennal scape with simple, short (<0.7× diameter of scape) setae along its inner margin.
Clypeus and supraclypeal area with minute, shallow punctures; frons with contigous, coarse punctures as on ocellocular area. Mesoscutum and mesoscutellum densely and coarsely foveate.
Provenance. The five type specimens were described by Cresson from material collected in Mexico by Adrien Louis Jean de Sumichrast (1828–1882), who collected from Veracruz-Llave, Puebla, México and Oaxaca (Tehuantepec) after his initial arrival to Mexico in April 1855, and until his death in Chiapas in 1882 (Papavero, 1971; Papavero & Ibáñez-Bernal, 2001). As the type specimen does not carry any additional information about where and when the specimen was collected, it is not possible to further trace the type locality other than Mexico. Nannotrigona perilampoides is a widespread species in Mexico, but it is noted that the other stingless bees collected by Sumichrast and described in the same paper by Cresson (Trigona nigra and T. thoracica), are restricted to the southern states of Mexico (Camargo & Pedro, 2007) where Sumichrast collected. The type locality could therefore be in Oaxaca or nearby states visited by Sumichrast.
Type material examined. 1 lectotype worker from Mexico, “Mex.”, “ LectoTYPE 2175” (red, 2175 handwritten) (ANSP). Four additional paralectotypes were not examined. The lectotype designation was made for specimen number 2175 by Cresson (1916).
Distribution. Mexico (Campeche, Chiapas, Chihuahua, Guerrero, Hidalgo, Jalisco, Michoacán de Ocampo, Morelos, Nayarit, Oaxaca, Puebla, Quintana Roo, San Luis Potosí, Sinaloa, Sonora, Tabasco, Veracruz-Llave, Yucatán, Zacatecas); Costa Rica (Alajuela, Cartago, Guanacaste, Heredia, Limón, Puntarenas); El Salvador; Guatemala (Escuintla); Honduras (Francisco Morazán); Panama (Canal Zone, Coclé, Colón, Panamá, Veraguas).
