Belokobylskij, Sergey A. & Achterberg, Cornelis Van, 2021, Review of the braconid parasitoid subfamily Doryctinae (Hymenoptera, Braconidae) from the United Arab Emirates and Yemen, European Journal of Taxonomy 765 (1), pp. 1-143 : 59-60

Genus Hecabalodes Wilkinson, 1929

Type species

Hecabalodes anthaxiae Wilkinson, 1929 , by monotypy.

Remarks

Hecabalodes is a small genus that is very similar to Leluthia . The main difference between these two genera is only in the distinctly shortened radial (marginal) cell of the fore wing, which is present in Hecabalodes . However, the shortened radial (marginal) cell also occurs in some species of Leluthia (e.g., L. ruguloscolyti ( Fischer, 1962) has an intermmediate-sized cell).

Distribution

Afrotropical, Oriental and Palaearctic regions.

Key to species of the genus Hecabalodes

1. Recurrent vein of fore wing (m-cu) postfurcal ( Figs 27A , 33A ). Radial (marginal) cell of fore wing long; its metacarpus (1-R1) 1.3–1.5 times longer than distance from apex of radial (marginal) cell to apex of wing ( Figs 27A , 33A ). Second radial abscissa (3-SR +SR1) of fore wing always almost straight ( Figs 27A , 33A ). African species ........................................................................................ 2

– Recurrent vein of fore wing (m-cu) antefurcal or sometimes interstitial ( Figs 29A , 31A ). Radial (marginal) cell of fore wing short; its metacarpus (1-R1) not longer than distance from apex of radial (marginal) cell to apex of wing. Second radial abscissa (3-SR +SR1) of fore wing aften more or less evenly curved, but sometimes almost straight ( Figs 29A , 31A ). Asian species ............................... 3

2. Vertex densely undulately transversely striate with rugulosity between striae ( Fig. 26B ). First metasomal tergite longer, lorger than its posterior width ( Fig. 27B ). Ovipositor sheath longer than metasoma ( Fig. 26A ). Body length 3.0–6.0 mm. – Sudan, UAE, Yemen.......................................... ............................................................................................................ H. anthaxiae Wilkinson, 1929

3. Vertex densely and coarsely transversely undulately striate with reticulation ( Fig. 28D ). Notauli complete and rather distinct posteriorly ( Fig. 28G ). Second radial abscissa (3-SR +SR1) of fore wing always distinctly evenly curved ( Fig. 29A ). Metacarpus (1-R1) distinctly shorter than distance from apex of radial (marginal) cell to apex of wing ( Fig. 29A ). Medial (basal) cell of fore wing almost glabrous or partly with very short setae ( Fig. 29A ). Body length 3.3–4.3 mm. – UAE......................................................................................... H. maculatus Belokobylskij sp. nov.

– Vertex only densely granulate, without striation ( Fig. 30C ). Notauli incomplete, almost absent posteriorly (fused with medio-posterior rugose area) ( Fig. 30E ). Second radial abscissa (3-SR +SR1) of for wing almost straight or weakly and not evenly curved ( Fig. 31A ). Metacarpus (1-R1) almost equal to distance from apex of radial (marginal) cell to apex of wing ( Fig. 31A ). Medial (basal) cell of fore wing almost rather distinctly setose by medium length setae ( Fig. 31A ) ............................. 4
