Eotrogaspidia saussurei ( Lelej, 2005) , comb. nov.

( Figs 3D, 3H , 4C, 4G , 6D , 7G , 9 F–G, 11C, 11F, 12G)

Mutilla luxuriosa Cameron, 1897: 67 , ♀ ( Ceylon [= Sri Lanka], specifically Trincomali [= Trincomalee] because most of the material collected by Yerbury originates from this place) [Oxford University Museum of Natural History, Oxford, UK], nom. praeocc. non Smith, 1879, objectively invalid name; André 1902: 40.

Trogaspidia saussurei Lelej, 2005: 101 ; Pagliano et al. 2020: 290. Replacement name for Mutilla luxuriosa Cameron, 1897 . Secondary junior homonym in Trogaspidia , non Trogaspidia saussurei Olsoufieff, 1938 , currently in the genus Chrysotilla Bischoff, 1920 . According to Article 59.2 of ICZN (1999), Eotrogaspidia saussurei ( Lelej, 2005) is a valid specific name.

Diagnosis. MALE. Clypeus deeply concave, shiny, with sculptured narrow anterior border ( Fig. 6D ); scape not widened apically; F1 strongly compressed, wider than F2. Pronotum with sparse subappressed and erect pale setae; propodeum dorsally with sparse pale setae and visible sculpture ( Fig. 3D ). Metacoxa beneath totally flattened and closed with very short dense pubescence ( Fig. 7G ). Hypopygium (S8) with short longitudinal lateral ridge reaching posterior 1/2 of sternum; cuspis lamellate, reaching posterior 1/2 of paramere. FEMALE. T2 pale setal spots small, distance between them 1.0 × or more than spot diameter ( Fig. 4C ); T3–4 with a pair of small lateral pale setal spots, distance between spots and that between spot and lateral margin of tergum approximately equal to spot diameter ( Fig. 4C ); pygidial plate with weak transversal curved rugae laterally oriented to apex ( Fig. 12G ).

Metacoxa mesally carinated, beneath flattened, with dense erect microsetae; procoxa beneath with smooth area; mesocoxa beneath with oblique carina. Propodeum reticulate, with larger cells dorsally; anterodorsally with large medial longitudinal and lateral transversal cells.

Forewings fuscous, submarginal cell 1 large, approximately equal in length to marginal cell; submarginal cell 2 receiving recurrent vein at midpoint; submarginal cell 3 less distinct than submarginal cell 2 and receiving recurrent vein in apical third.

Longitudinal carina on S1 well developed, 3/4 × as long as S 1 in profile. T1–6 and posterior halves of S3–6 with moderately fine, well separated punctures, much sparser on T2 disc; S2 with moderately coarse, separated punctures; S7 with lateral tubercle; S8 (hypopygium) laterally with longitudinal carina oriented mesally, 1/2 × as long as S 8 in profile; T7 with moderately coarse, dense punctures; T7 medially with narrow widened apically shiny area. Paramere down-curved posteriorly with pointed apex; inner margin of paramere dorsally with row of short erect golden setae; parapenial lobe large, rounded; cuspis long lamelliform, apex rounded, clearly surpassing apex of penis valve, ventrally with dense long erect golden setae; digitus stick-like setose, much shorter than cuspis; paracuspis stick-like setose, shorter than digitus; penis valves weakly asymmetrical, right penis valve slightly longer that left, with posterior ventral hook; left valve with ventral apical hook.
