Andinobrachys gen. nov.
( Figs. 1−3 View FIGURE 1 View FIGURE 2 View FIGURE 3 )
Type species: Andinobrachys montanus sp. nov.
Diagnosis. Large sharpshooters (16.0− 16.2 mm). Body coloration ( Figs. 2A, B View FIGURE 2 , 3A, B View FIGURE 3 ) mostly yellow and ochraceous to brown (green in live specimens, Fig. 1C View FIGURE 1 ); anterodorsal tuberosities of crown yellow. Head ( Figs. 2A, B View FIGURE 2 , 3A, B View FIGURE 3 ) moderately produced anteriorly; crown ( Figs. 2A View FIGURE 2 , 3A View FIGURE 3 ) anterior portion subquadrate, with two anterolateral tuberosities, apical margin concave, median area of the concavity somewhat projected anteriorly; transition between crown and face with a transverse median carina, between anterolateral tuberosities. Pronotum ( Figs. 2A View FIGURE 2 , 3A View FIGURE 3 ) width almost as wide as transocular width of head; in dorsal view with lateral margins convergent anteriorly; dorsopleural keel ( Fig. 2B View FIGURE 2 , 3B View FIGURE 3 ) absent. Forewing ( Figs. 2A, B View FIGURE 2 , 3A, B View FIGURE 3 ) brachypterous, exposing five abdominal terga; coriaceous and conspicuously punctate; without membrane. Hind wing also brachypterous, shorter than forewing, but longer than half forewing length. Male pygofer ( Fig. 2C View FIGURE 2 ) produced posteriorly, without a posteroventral process. Connective ( Fig. 2E View FIGURE 2 ), in dorsal view, with stem almost as long as arms, widening apically, not keeled. Style ( Fig. 2E View FIGURE 2 ) apodeme broad and long, almost as long as apophysis; base of outer apical margin of style with two little tuberosities adjacent to preapical lobe; apex digitiform. Aedeagal shaft, in lateral view ( Fig. 2F View FIGURE 2 ), elongate; with a basidorsal wide and triangular projection expanded dorsally, anterior margin of projection with a short and acute process, posterior margin irregular, somewhat serrated, with irregularities continuing dorsally until shaft apex; shaft apex, in lateral view ( Fig. 2F View FIGURE 2 ), curving ventrally and anteriorly, hooklike; in ventral and caudal views ( Fig. 2G, H View FIGURE 2 ), flattened dorsoventrally and wide, sagittate in form, with lateral margins serrated. Paraphyses ( Fig. 2 View FIGURE 2 F−H) paired, slender, and elongate; basally fused to a broad plate; extending posteriorly beyond shaft apex by a short distance; apex acuminate.
Description. Crown ( Figs. 2A View FIGURE 2 , 3A View FIGURE 3 ) moderately produced anteriorly, median length of crown approximately two-thirds interocular width and approximately one-half transocular width of head; with pubescence; anterior portion ( Figs. 2A View FIGURE 2 , 3A View FIGURE 3 ) subquadrate and with two lateral tuberosities; apical margin concave, median area of the concavity somewhat projected anteriorly; disk ( Figs. 2A View FIGURE 2 , 3A View FIGURE 3 ) with a distinct depression extended to apical margin, becoming more pronounced and foveate between lateral tuberosities; posterior portion with two strong posterolateral concavities, adjacent to each eye; posterior margin without a distinct M-shaped elevation ( Figs. 2A View FIGURE 2 , 3A View FIGURE 3 ). Head, in lateral view, with anterior portion of crown not inflated ( Figs. 2B View FIGURE 2 , 3B View FIGURE 3 ) forming an acute angle with frons; transition from crown to face with a transversal median carina between lateral tuberosities. Ocelli present but small and somewhat rudimentary ( Fig. 2A View FIGURE 2 ) or absent ( Fig. 3A View FIGURE 3 ); when present, aligned with anterior eye angles and equidistant from median line of crown and adjacent eye angle. Antennal ledges ( Figs. 2B View FIGURE 2 , 3B View FIGURE 3 ) carinate dorsally, without a longitudinal fovea; anterior edges steeply declivous. Face ( Figs. 2B View FIGURE 2 , 3B View FIGURE 3 ) conspicuously pubescent. Frons ( Figs. 2B View FIGURE 2 , 3B View FIGURE 3 ) strongly convex medially; muscle impressions distinct. Clypeus ( Figs. 2B View FIGURE 2 , 3B View FIGURE 3 ) protuberant, its contour almost at right angle to profile of face; without a median carina.
Pronotum ( Figs.2A View FIGURE 2 , 3A View FIGURE 3 ) width almost as wide as transocular width of head; lateral margins convergent anteriorly; surface punctate, rugose, and pubescent; pubescence more densely aggregated on posterior part; posterior portion inflated; posterior margin concave, forming two lobes; in lateral view ( Figs. 2B View FIGURE 2 , 3B View FIGURE 3 ), clearly declivous anteriorly; dorsopleural keel absent. Mesonotum ( Figs. 2A View FIGURE 2 , 3A View FIGURE 3 ) texture smooth; posterior half, posterior to scutellar suture, somewhat inflated; metepimeron without a shelf-like projection. Forewing ( Figs. 2A, B View FIGURE 2 , 3A, B View FIGURE 3 ) brachypterous, exposing at least abdominal terga IV-IX; texture strongly coriaceous, without venation and membrane, uniformly punctate and pubescent.Hind wing ( Figs. 2A View FIGURE 2 , 3A View FIGURE 3 ) brachypterous, shorter than forewing; vein R 2+3 ( Fig. 3A View FIGURE 3 ) complete. Profemur with setal row IC and AM multiseriate; setae subequal in aspect and indistinct from AV. Metafemur in rest position reaching lateral lobes of pronotum; femoral setal formula 2:0:0. Metatibia with AD and PD rows of cucullate setae similar in size, but not in number (PD more setose than AD, but not reaching double the amount of setae); bristle-like setae may be present in spaces between cucullate setae of both AD and PD; PD row with setae irregularly spaced; AV and PV rows of setae unmodified. Metatarsus with first tarsomere as long as combined length of second and third.
Distribution. Colombia.
Etymology. The generic name Andinobrachys is a masculine form derived from two components: “Andino” referring to the Andes, the South American Mountain Range where this genus occurs, and “brachys” from the Greek βραχύς, meaning “short” or “reduced”, in reference to the short wings (brachyptery) characteristic of the species in this genus.
Remarks. Andinobrachys gen. nov. was recovered in the phylogenetic analysis of Feng et al. (2024), then named as “ Proconiini sp. 2”, as sister group to Splonia dietrichi Takiya & Mejdalani, 2011 . These two genera are extremely similar in their external morphology (when comparing with brachypterous species of Splonia ), however, the new genus can be separated mostly by characters of the head, such as the anterior portion of the crown ( Figs. 2A View FIGURE 2 , 3A View FIGURE 3 ) with two lateral tuberosities (without tuberosities in Splonia ), without processes (with an apical process which extends anterodorsally in Splonia ); and the disk of the crown ( Figs. 2A View FIGURE 2 , 3A View FIGURE 3 ) with a distinct depression extended to the apical margin, becoming more pronounced and foveate between lateral tuberosities (disk flat without median fovea or depressions in Splonia ).
