Román, Andrea C., Almeida, Luis Felipe Ventura De, Penteado-Dias, Angelica, Shaw, Scott Richard & Sarmiento, Carlos E., 2025, Analysis of morphological variation and description of fifteen new species of the genus Centistes Haliday (Hymenoptera: Braconidae: Euphorinae: Centistini) with a key of the South American species, Zootaxa 5613 (1), pp. 1-46 : 27

Centistes lobungula Román & Sarmiento sp. nov.

( Figs. 17A–G , 24D , 26E )

Diagnosis: This species differs from the others by the basal lobe of the claws ( Fig. 26E ) and the smooth first tergite.

Comments: The basal lobes in the claws of C. lobungula had not been reported in other species of the genus.

Description. Female. Body length: mesosoma length 1.37 (1.37–1.38) mm. Head ( Figs. 17B–C ): antenna with 24 flagellomeres; face setose and smooth, minimum face width equal to its clypeus width; face length equal to its maximum face width; clypeus setose and smooth, clypeus length 0.5 × its width; gena setose and smooth; frons smooth; vertex sparsely setose and smooth; mandibles when closed overlapping 0.3 × mandibles length, mandible width basally 0.5 (0.4–0.5) × mandibles length; malar space length 0.2 × eye height in lateral view, and equal to mandible width basally; eye height in lateral view 1.4 (1.4–1.5) × eye length in dorsal view; lateral ocellus separated from compound eye 0.9 × ocellus diameter; temple length 0.8 × eye length in dorsal view. Mesosoma ( Figs. 17D, G ): pronotum glabrous, transverse dorsal sulcus absent; pronotum in lateral view sparsely setose, smooth, without carinae; median and lateral mesonotal lobes sparsely setose anteriorly, smooth; pit on the mesoscutum absent; notauli absent; mesoscutum width 1.1 × its length; scutellar sulcus with transverse carina; scutellum sparsely setose, smooth; posterior scutellar depression scrobiculate; mesopleuron setose with a glabrous area medially, smooth; precoxal sulcus absent; metapleuron setose, metapleuron upper part scrobiculate and lower part smooth, supramesocoxal projection present; propodeum glabrous, not truncated, dorsally and posteriorly smooth, dorsal areola absent, medial longitudinal carinae absent, lateral longitudinal carinae in dorsal view incomplete, transverse dorsal carinae absent; propodeal areolae present, hexagonal; Legs ( Fig. 17A ): tibia and tarsus highly setose; tarsus I to IV of fore legs without brush-like pubescence; claws basal lobe present. Wings ( Fig. 24D ): vein (RS+M)a absent, stigma length 0.7 × marginal cell length and equal to vein R1 length, vein r length 0.1 × stigma length, vein 1CUa length 0.07 (0.07–0.09) × vein 1CUb length. Metasoma ( Figs. 17E–F ): first tergite smooth, without longitudinal carinae, first tergite length 1.9 (1.9–2.0) × ovipositor sheath length; hypopygium setose; ovipositor sheath sparsely setose, short, oval, sheath tip round, thin plate on the edge absent, ovipositor sheath length 2.7 × its width. Coloration ( Fig. 17A ): Head dark brown except clypeus and mandible yellow; mesosoma dark brown except propleura yellow and brown; coxa yellow, femur of leg I and II yellow, leg III yellow with a brown base, tibia of leg I yellow, leg II brown, leg III dark brown, tarsus dark brown, tegula yellow; wing hyaline, veins and stigma yellow; metasoma dark brown and yellow except ovipositor sheaths dark brown.

Male: Unknown.

Examined Material: Holotype female: COLOMBIA, Boyacá, Santuario de Fauna y Flora Iguaque , Cabaña Carrizal, N 5°25’ W 73°27’, 2850 m, Malaise, 22-viii-2001 – 12-ix-2001, P. Reina leg. (Deposited in IaVH. Code: M.2065 ).

Paratype: one female, COLOMBIA, Boyacá, Santuario de Fauna y Flora Iguaque , Cabaña Carrizal, N 5°25’ W 73°27’, 3350 m, Malaise, 30-vii-2000 – 17-viii-2000, P. Reina leg. (Deposited in IaVH. Code: M.392 ) .

Etymology: The specific epithet for this species is composed of the Latin words lobulu s, meaning lobule, and ungula, meaning claw, referring to the basal lobe in their claws.
