( Figs. 2 View Figure 2 A-F, 3B, D, 4C, 5, 6)

Diagnosis: Female with first flagellomere longer than scape ( Fig. 2B View Figure 2 ); head ( Fig. 2 View Figure 2 A-C) mostly black, reticulate rugose; posterior surface of pronotum ( Fig. 2D View Figure 2 ) less than twice as broad as long, punctate, unsculptured among punctures; notauli reaching about 0.8 × length of mesoscutum ( Fig. 2D View Figure 2 ); fore wing with two dark transverse bands ( Fig. 3B View Figure 3 ); posterior surface of propodeum completely reticulate rugose ( Figs. 2 View Figure 2 E-F); 5 th protarsomere with very short rows of lamellae situated only in the distal half ( Figs.3D View Figure 3 , 5C View Figure 5 ) and with two very long distal lamella ( Fig. 5C View Figure 5 ).

Description: Female ( Fig. 2A View Figure 2 ): Fully winged; body length 7.6 mm. Color: Head ( Figs. 2 View Figure 2 A-B) black, except anterior half of frons and lower area of face testaceous; clypeus testaceous; lower genal area ( Figs. 2 View Figure 2 A-B) with one narrow testaceous band; mandible testaceous, except teeth brown; antenna ( Fig. 2A View Figure 2 ) testaceous, except flagellomeres 5-8 darkened; mesosoma ( Fig. 2A, E View Figure 2 ) black, except lateral surface of pronotum ( Figs. 2A, D View Figure 2 ) testaceous; fore wing ( Fig. 3B View Figure 3 ) with two dark transverse bands; legs ( Fig. 2A View Figure 2 ) red testaceous, except procoxa, mesocoxa, metacoxa and part of metafemur black; petiole black; metasoma black, except last tergum and sternum partially testaceous. Pubescence: Head ( Fig. 2C View Figure 2 ) with fine and sparse pilosity, except part of face, clypeus and gena with short and dense pilosity; pronotum ( Fig. 2D View Figure 2 ) with long and dense pilosity; mesoscutum, mesoscutellum and metanotum ( Figs. 2 View Figure 2 D-E) with fine and sparse pilosity; legs ( Fig. 2E View Figure 2 ) with fine and erect pilosity; mesopleuron ( Fig. 2E View Figure 2 ) with fine and dense pilosity; metapleuron ( Fig. 2E View Figure 2 ) with fine and short pilosity; propodeum ( Fig. 2F View Figure 2 ) and metasoma with fine and erect pilosity. Integumental sculpture: Head ( Figs. 2A, C View Figure 2 ) reticulate rugose, except irregular carinae near to ocellus; clypeus rugose ( Fig. 2B View Figure 2 ); gena punctate, with surface rugose; vertex ( Fig. 2C View Figure 2 ) reticulate rugose, with rugosity less distinct than that of frons; occipital carina ( Fig. 2C View Figure 2 ) complete; frontal line ( Fig. 2B View Figure 2 ) absent; pronotum ( Fig. 2D View Figure 2 ) with anterior collar rugose and disc sparsely punctate, smooth among punctures; mesoscutum ( Fig. 2D View Figure 2 ) more sparsely punctate than disc of pronotum; notauli ( Fig. 2D View Figure 2 ) incomplete, reaching about 0.8 × length of mesoscutum; mesoscutellum ( Fig. 2D View Figure 2 ) partially punctate, unsculptured among punctures; metanotum with central region unsculptured and lateral sides punctate; mesopleuron ( Fig. 2C View Figure 2 ) rugose and partially punctate; metapleuron ( Fig. 2C View Figure 2 ) rugose; propodeum reticulate rugose. Structures and Proportions: Ocellar ratio: OL = 7; POL = 8; OOL = 35; OPL = 27; TL = 35. Antennomeres in following proportions: 48:25:50:35:30:27:25:25:23:30. Protarsomeres in following proportions: 35:10:20:36:75. Enlarged claw slightly shorter than 5 th protarsomere (70:75), with inner proximal prominence bearing one long bristle; 5 th protarsomere ( Figs. 3D View Figure 3 , 5C View Figure 5 ) with very short rows of lamellae situated only in the distal half; apex with a set of lamellae, two of which very long. Claw of midle and posterior legs with basal expansion very development. Stigmal vein of fore wing ( Fig. 3B View Figure 3 ) with distal part (3Rs&4Rs) slightly longer than proximal part (2r-rs) (48:38). Dorsal surface of propodeum shorter than posterior surface (35:75). Tibial spurs 1:1:2.

Male: Unknown.

Distribution: Deinodryinus mexicanus sp. nov. is known only by two females collected in Mexico, Chiapas ( Fig. 6 View Figure 6 ).

Type material: Mexico: Holotype: ♀, México, Chiapas, 4km \ W de San Cristóbal,\ Huiotepec, 2420 m,\ 13-19. viii.2013,\ 16.7397°N 92.6798°W,\ Melo & Rosa, Malaise ( DZUP). Paratype: Mexico: 1 ♀, same data of holotype ( DZUP).

Etymology: The name mexicanus is a Latinized word meaning ‘from Mexico’, where this species has been collected.

Remarks: Among the species of Deinodryinus from the Neotropical region, D. mexicanus sp. nov. is similar to D. incaicus Olmi, 1984 . They share region of head behind posterior ocelli without two oblique carinae connecting posterior ocelli to occipital carina; posterior surface of pronotum completely or almost completely smooth, punctate, unsculptured among punctures; 5 th protarsomere apex with a set of lamellae, two of which are longer, and fore wing with two dark transverse bands.

Following the description of D. mexicanus sp. nov., the key to the females of the Neotropical Deinodryinus published by Olmi & Virla (2014) should be modified by replacing couplet 73 as follows:

73. Region of head behind posterior ocelli without two oblique keels connecting posterior ocelli to occipital carina ( Fig.2C View Figure 2 );5 th protarsomere with one-two very long distal lamellae ( Fig. 5C View Figure 5 ; and Fig. 59E in Olmi & Virla,2014)..........................................................................................73’

— Region of head behind posterior ocelli with two complete or incomplete oblique keels connecting posterior ocelli to occipital carina; 5 th protarsomere without one-two very long distal lamellae (Plates 52E, 58H in Olmi &Virla,2014)....................................................................74

73’ 5 th protarsomere with very long rows of lamellae, situated both in proximal and distal half (Fig.59E in Olmi &Virla,2014).. D.incaicus Olmi.
