Head. Antenna as in figure 70. HE/MS/MO=1.9/1.0/1.3. Frons with weak small meshed reticulation, meshes ± transverse. Vertex with very weak reticulation in front of vertexal suture, behind suture with strong small-meshed reticulation and ± wrinkled. POL/OOL/POO: 1.4/1.0/not measurable. Occipital margin rounded. WH/WT=1.4.

Mesosoma . Mesoscutum and scutellum smooth and shiny with weak traces of reticulation; scutellum 0.6× as long as wide. Dorsellum visible as a narrow stripe, smooth. TPS distinctly curved. Fore wing with three to six admarginal setae; submarginal vein with three setae; LW/LM/HW: 1.8/1.2/1.0; PM/ST =0.5. Propodeum smooth and shiny, with a complete median groove.

Metasoma. Petiole 0.5× as long as wide. MM/LG=0.7–0.9.

Genus Monterrondo gen. n. Type species: M. aphelosoma sp. n.

Diagnosis

Flagellum with two funicular and three claval segments (figure 91); clypeus not delimited; malar sulcus straight and complete (figure 90); scrobes present and Y-shaped (figure 90); frontal suture absent; vertexal suture absent; occiput with a longitudinal median groove, but without a transverse groove; mid lobe of mesoscutum with two pair of setae (figure 3); axilla delimited from mesoscutum by a sulcus (figure 3); scutellum with two pair of setae situated close to margins (figure 3); meso- and metapleuron smooth and shiny, pleurites completely fused, the only sulcus present is the one along posterior the border of prepectus, all other sulci are absent; fore wing large (3.1× as long as length of mesosoma) (figure 3); marginal and postmarginal veins short (marginal 0.6× as long as wing; postmarginal 0.1× as long as stigmal vein) (figure 3); stigmal vein long and slender (5.2× as long as width at apex) (figure 3); propodeal callus with two long setae (figure 3); second gastral tergite membranous in anterior one-third (figure 3); with anterolateral abdominal glands (ALAGs), situated on anterolateral gaster (as in Euderomphale (figure 16)); sixth gastral tergite predominantly membranous, with two small plates, each with a spiracle (as in Euderomphale (figure 15)); apical parts of ovipositor sheaths elongate (2.9× as long as wide and 0.4× as long as length of entire ovipositor sheaths).

Monophyly and relationships

Monterrondo belongs in the Euderomphale genus group, indicated through: occiput with a longitudinal median groove; mesoscutum and scutellum flattened dorsally; mid lobe of mesoscutum with two pair of setae; axilla situated entirely anterior to scuto-scutellar sulcus; scutellum transverse with two pair of setae; submarginal vein with two setae on dorsal surface; second gastral tergite membranous in anterior onethird. Monterrondo shares character states with either Euderomphale or with Neopomphale , but also possesses unique character states. Character states shared with Euderomphale : frontal suture absent (apomorphy); axillae completely delimited from mesoscutum through a sulcus (plesiomorphy); mesoscutum with two pair of setae (plesiomorphy); scutellum with two pair of setae (apomorphy); sixth gastral tergite predominantly membranous, with two small plates, each with a spiracle (apomorphy). Character states shared with Neopomphale : malar sulcus straight and complete (plesiomorphy); scrobes present and Y-shaped (polarity uncertain); axilla longer than wide (plesiomorphy), and situated anterolaterad to scutellum (plesiomorphy). Character states unique to Monterrondo : clypeus not delimited (reversal); vertexal suture absent (reversal); transverse occipital groove absent (reversal); posterior pair of scutellar setae as long as anterior pair (apomorphy); meso-and metapleuron smooth and shiny, only posterior border of prepectus indicated through a sulcus, all other pleurites are completely fused and sulci are absent (apomorphy).

Another apomorphy shared with Euderomphale is an everted anterolateral abdominal gland (ALAG), which can be seen on the holotype of M. aphelosoma . The presence of ALAGs in Euderomphale was mentioned by LaSalle and Polaszek (2000), although they were previously unknown in other euderomphalines.

Description

Flagellum in female with one small and discoid anellus, two funicular segments and a three-segmented clava. Mandibles with two teeth. Clypeus not delimited. Scrobes present and Y-shaped; frontal suture absent. Vertexal suture absent. Occiput with a longitudinal median groove, but without a transverse groove. Eyes ± hairy.

Pronotum reduced and strongly narrowed medially, not visible in dorsal view. Thoracic dorsum flat, with weak engraved reticulation, some parts smooth and shiny; notauli absent. Mid lobe of mesoscutum with two pair of setae, one pair close to anterior margin and one pair in front of axillae; scutellum transverse, 0.8× as long as wide, with two pair of setae situated close to margin of scutellum, anterior pair situated medially, posterior pair closer to hind margin. Axillae situated anterior to scuto-scutellar sulcus. Transepimeral sulcus absent, as are most other sulci on pleurae, only sulcus between prepectus and posterior mesopleuron present. Propodeum smooth and shiny, spiracular sulcus absent; propodeal callus with two elongate setae. Fore wing with two setae on submarginal vein; costal cell as wide as base of submarginal vein; with surface below marginal vein infuscate; speculum absent; postmarginal vein 0.1× as long as stigmal vein.

Petiole not visible, presumably short and transverse. Female with second gastral tergite membranous in anterior one-third (figure 3); sixth gastral tergite predominantly membranous, with two small plates, each with a spiracle; apical parts of ovipositor sheaths elongate (2.9× as long as wide and 0.4× as long as length of entire ovipositor sheaths).
