Asilidae consists of 14 subfamilies, and Asilinae is the subfamily which has the largest number of genera and species described. Currently there are 177 genera and 2520 valid species known. Asilinae is taxonomically very complex in comparison to other Asilidae and generic limits are not easy to define and distinguish either. The greatest difficulty in
Asilinae is the great similarity between species and genera. In Chapter 1, a morphological phylogenetic study of Asilinae, based on a sample of 102 genera (including two new genera) and 186 known species as the ingroup and 24 outgroup
species, is presented. The parsimony analysis was done using two algorithms of the new technology search of TNT, Tree Drifting and Ratchet. The initial search of 300 RAS +
TBR resulted in 30 trees of 3.826 steps length. After 1.500 iterations of the parsimony ratchet 66 trees of 3.819 steps were found and after na additional 1.500 rounds of tree
drifting, three equally most parsimonious trees of 3.818 steps length were found. The strict consensus of these trees has 3.876 steps. The monophyly of Asilinae is supported by two homoplasies: R4 and R5 approximating each other distally (medially farthest apart) and female sternite VIII longer than wide, apex with constriction. Asilinae is divided into six tribes: Apocleini, Asilini, Blepharotini new tribe, Efferiini new tribe, Mallophorini new tribe and Proctacanthini new tribe. In chapter 2, three new species from Brazil of Diplosynapsis Enderlein, 1914 D. chela sp. nov. (Amazonas), D. spina
sp. nov. (Rio de Janeiro) and D. uncinata sp. nov. (Amazonas) were described. Furthermore, a lectotype for Diplosynapsis cellata (Schiner, 1868) is designated and D. remus Tomasovic, 2002 is transferred to Efferia as a new ombination. Diplosynapsis Enderlein, 1914 is a Neotropical genus and is characterized by cells r1 and r2 +3 closed.
In this chapter a new genus of Asilinae with five new species from Brazil are described: Longivena gen. nov. (Type-species: Longivena digitata sp. nov., Bahia), Longivena
albina sp. nov. (Mato Grosso do Sul), Longivena bilobata sp. nov. (Maranhão), Longivena spatulata sp. nov. (Maranhão) and Longivena limeiraoliverai sp. nov. (Maranhão). In chapter 3, the female of Ctenodontina nairae Vieira, 2012, a new genus Nordestina gen. nov., type-species: Nordestina ayalai sp. nov. from Brazil (Maranhão) and six new species: Proctacanthella longipenis sp. nov. from Brazil (Goiás), Martintella aurata sp. nov. from Costa Rica (Guanacaste), Martintella guanacastensis sp. nov. from Costa Rica (Guanacaste), Nordestina ayalai sp. nov. from Brazil (Maranhão), Cerozodus arcadensis sp. nov. from Brazil (Bahia), Eichoichemus maranhensis sp. nov. from Brazil (Maranhão) are described. Comments on the status of
Asilus mellipes Wiedemann, 1828 are provided; Aristofolia Ayala-Landa, 1978 is revalidated; a new combination is: Efferia tristis (Wiedemann, 1828) comb. nov. is
proposed; Martinofurcilla Özdikmen, 2010 syn. nov. is synonymized with Scarbroughia Papavero, 2009. |
