Deinodryinus pratapolensis Martins , sp. nov.

( Figs 1–7 View FIGURES 1 – 5 View FIGURES 6, 7. 6 A )

Diagnosis. Female, with mesosoma black, except posterior surface of pronotum, pronotal tubercle, anterior surface of lateral region of pronotum, scutum, scutellum and metanotum testaceous; frontal line complete; occipital carina complete; notauli reaching about 0.5 length of scutum. Pronotal tubercle reaching tegula. Propodeum with strong transverse keel between dorsal and posterior surface. Enlarged claw with one bristle located further distally than proximal prominence. Fore wing hyaline, without dark transverse bands; proximal part of stigmal vein much longer than distal part.

Description. Female. Fully winged ( Fig. 1 View FIGURES 1 – 5 ); length 4.5 mm. Head black, except mandible and clypeus testaceous; antenna testaceous, except segment 10 slightly darkened; mesosoma black, except posterior surface of pronotum, pronotal tubercle, anterior surface of lateral regions of pronotum, mesoscutum, mesoscutellum and metanotum testaceous; metasoma brown; legs testaceous, except basal half of metacoxa black. Antenna clavate; antennal segments in following proportions: 17:8:17:9:7:8:9:8:8:10. Head shiny, very slightly granulated (sculpture hardly visible); face with complete frontal line and two lateral longitudinal keels around orbits and directed towards antennal toruli (surface between keels slightly granulated, rugose on anterior half of face) ( Figs 2, 3 View FIGURES 1 – 5 ); vertex behind ocellar triangle with two oblique keels connecting posterior ocelli to occipital carina; occipital carina complete ( Fig. 3 View FIGURES 1 – 5 ); POL = 2; OL = 3; OOL = 8; OPL = 10; TL = 9; greatest breadth of posterior ocelli as long as OL. Pronotum shiny, strongly sculptured by numerous transverse keels; posterior surface shorter than broad (12:22), shorter than mesoscutum (12:21); pronotal tubercle reaching tegula. Pronotum ( Fig. 6 View FIGURES 6, 7. 6 A B: p) raised into a transverse carina in lateral view. Mesoscutum, mesoscutellum and metanotum shiny, finely punctate, unsculptured among punctures. Notauli incomplete, reaching approximately 0.5 length of mesoscutum ( Fig. 4 View FIGURES 1 – 5 ). Metanotum ( Fig. 6 View FIGURES 6, 7. 6 A B: m) inclined, with anterior margin raised from scutellum level. Propodeum with strong transverse keel between dorsal and posterior surface; dorsal surface reticulate rugose; posterior surface reticulate rugose, without longitudinal keels. Fore wing hyaline, without dark transverse bands; distal part of stigmal vein shorter than proximal part (6:12) ( Fig. 5 View FIGURES 1 – 5 ). Protarsal segments in following proportions: 14:2:5:17:26. Enlarged claw ( Fig. 7 View FIGURES 6, 7. 6 A ) with one bristle located further distally than proximal prominence. Segment 5 of protarsus ( Fig. 7 View FIGURES 6, 7. 6 A ) with two rows of approximately 47 lamellae; distal apex with about three lamellae, among which one very long. Pro- and mesotibia with 1, metatibia with 2 spurs.

Male. Unknown.

Material examined. Holotype, ♀, BRAZIL: Minas Gerais, Pratápolis, gallery forest, 20º44’41.6”S 46º52’37.6”W, Yelow pan trap, 15.X.2009, A.L. Martins leg. ( DZUP).

Hosts. Unknown.

Distribution. Brazil (Minas Gerais).

Etymology. This species is named after the town in which it was collected (municipality of Pratápolis).

Remarks. Because of the head with two complete keels connecting posterior ocelli to occipital carina, face with one median longitudinal keel, notauli reaching about 0.5 length of mesoscutum, fore wing hyaline, distal part of protarsal segment 5 not forming right angle with rest of segment, Deinodryinus pratapolensis sp. nov. can be included in the key to the females of the Neotropical Deinodryinus presented by Olmi & Virla (2014) at couplet 20’, near D. broomfieldi Olmi, 2010 .The new species differs from D. broomfieldi by having pronotum raised into a transverse carina ( Fig. 1 View FIGURES 1 – 5 B: p) (rounded in D. broomfieldi ( Fig. 1 View FIGURES 1 – 5 A: p), by metanotum inclined and with anterior margin raised from mesoscutellum level ( Fig. 1 View FIGURES 1 – 5 B: m) (rounded in D. broomfieldi ( Fig. 1 View FIGURES 1 – 5 A: m) and by mesosoma black, except posterior surface of pronotum, pronotal tubercle, anterior surface of lateral region of pronotum, mesoscutum, mesoscutellum and metanotum testaceous ( Figs 1, 4 View FIGURES 1 – 5 ) (mesosoma black, except posterior margin of pronotum testaceous, in D. broomfieldi ).

Amended key to the species (females only) of Neotropical Deinodryinus (modified from Olmi & Virla 2014).
