Cicatrix Paretas-Martinez ZBK gen. n. Fig. 2 View Figure 2
Type species:
Cicatrix pilosiscutum (Girault), comb. n.
Included species:
Cicatrix neumannoides , sp. n., Cicatrix pilosiscutum (Girault), Cicatrix shauffi (Buffington), comb. n.
Diagnosis.
( Table 2 View Table 2 ) Cicatrix , gen. n., is distinguished from Myrtopsen , Palmiriella , gen. n., and Scutimica by having T3 and T4 as separate sclerites ( Fig. 2C View Figure 2 ); in these latter three genera, T3 and T4 are fused into a syntergum ( Fig. 3F View Figure 3 , 9C View Figure 9 ). Cicatrix is distinguished from Thrasorus having horizontally striate microsculpture on the mesoscutum ( Fig. 2B, E View Figure 2 ); Thrasorus has a smooth mesoscutum ( Fig. 4B View Figure 4 ).
Description.
Length. Female2.5 - 4.5 mm.Male unknown.
Coloration. The entire body with the same coloration, light brown or chestnut depending on the specimen.
Head ( Fig. 2A, D View Figure 2 ). Face and frons with abundant setae. Face with transverse carinae, strong across entire face, or only marked at lateral sides of face, smoother, tending towards strigae. Clypeus distinctly projected anteriorly, curved ventrally, clypeopleurostomal lines well developed. Malar furrow coriaceous. Occiput and genae smooth without carinae. Circumtorular impression present.
Antennae ( Fig. 2F View Figure 2 ). Female. Filiform, with 10 or 11 flagellomeres.
Mesosoma ( Fig. 2B and E View Figure 2 ). Pronotal carinae reaching anterior margin of mesoscutum, forming small plate, conspicuous but not projected, concave dorsomedially. Mesoscutum horizontally striate. Notauli complete, of uniform width to slightly wider posteriorly. Parascutal sulcus wide only in basal half. Lateral basal impressions conspicuous. Antero-admedian lines weak. Median mesoscutal line absent, short or long. Scutellum rugose; scutellar foveae round, subtriangular or subquadrate; interfoveal carina absent. Mesopleural furrow conspicuous. Propodeal carinae wide, curved. Pronotum, mesoscutum, scutellum, mesopleural triangle and metapleura all covered with sparse/dense setae.
Forewing. Short setae present on wing surface and along margins. Radial cell closed along anterior margin, two times longer than wide, R2 almost straight; areolet absent.
Legs. Metatibia with two spurs, sub-equal in length, not exceeding one-half length of tarsomere 1.
Metasoma ( Fig. 2C View Figure 2 ). Petiole short. Base of T3 with patches of setae or an almost complete hairy ring. Tergite 3 smaller than T4; T4 four large, covering almost entire metasomal surface; remaining terga short, telescoped within T4; entire metasoma shiny, smooth. Hypopygium and ventral spine visible.
Biology.
Unknown.
Distribution.
Australia.
Etymology.
From the Latin word cicatrix, meaning “scar”, refering to the carinae that resemble a scar through the face. Gender is masculine.
Taxonomic comments.
Girault (1929) described Amblynotus pilosiscutum, and Weld (1952) transferred the species to Melanips . This species has the circumtorular impression and thus belongs to Thrasorinae . However, the results of the phylogenetic analysis and the diagnostic characters summarized above indicate that this species cannot be accommodated by any currently recognized genus, thus we describe Cicatrix , gen. n., to contain Cicatrix pilosiscutum (Girault) as well as Cicatrix neumannoides , sp. n., and Cicatrix schauffi (Buffington), comb. n.
