Revision of genus Repipta Stål 1859 (Hemiptera: Heteroptera: Reduviidae: Harpactorinae) with new species and distribution data

Abstract

A revision was made of Repipta Stål, mostly a Neotropical genus with some species in the Neotropics and the Nearctic. Thirteen known species are redescribed: R. annulipes Barber, R. antica Stål, R. coccinea (Herrich-Schaeffer), R. flavicans (Amyot & Serville), R. fuscospinosa Stål, R. fuscipes Stål, R. lepidula Stål, R. mucosa Champion, R. nigronotata Stål, R. obscuripes Stål, R. sexdens (Fabricius), R. spinosa (Fabricius), and R. taurus (Fabricius). Twelve new species are described and illustrated, including data on male and female genitalia, new distributional records, and key to the species.

First description of the male and redescription of the female of Parahiranetis salgadoi Gil-Santana (Hemiptera, Reduviidae, Harpactorinae)

“…Two of the sexual differences pointed out in P. salgadoi (i.e. females larger than males and the latter with third antennal segment thickened) are concordant with several observations in the literature (Champion 1899, Martin-Park et al 2012, Gil-Santana et al 2013, Gil-Santana 2016). Additionally, the thickened portion of the third antennal segment in males was completely covered by very short, stiff, adpressed, blackish setae (Figs 9–10, 12), which were absent in females (Fig.…”

“…In addition to the bigger size and larger abdomen of females, males in several genera have larger eyes and/or a basally-thickened third antennal segment. The latter has been considered to be among the diagnostic features at generic level (Stål 1872, Champion 1899, Martin-Park et al 2012, Gil-Santana et al 2013, Gil-Santana 2016). However, sexual dimorphism may also be limited to minor differences in coloration and size, as in many species of Zelus (Zhang et al 2016).…”

First description of the male of Hiranetis atra Stål and new country records, with taxonomic notes on other species of Hiranetis Spinola (Hemiptera, Heteroptera, Reduviidae, Harpactorinae)

“…6). This form of sexual dimorphism has been recorded in several genera of Harpactorini (Stål 1872, Champion 1898, Gil-Santana et al 2013, Martin-Park et al 2012) and in another species of Hiranetis , Hiranetis braconiformis (Champion 1898). The minor differences in coloration between the male and female examined were probably due to intraspecific variation, as already recorded in other species of Hiranetis (Spinola 1840, Herrich-Schäffer 1848, Champion 1898).…”

“…In addition to the bigger size and larger abdomen of females, which is common in many other insects, males in several genera have larger eyes and/or the thickening of the third antennal segment in its basal portion. The latter has been considered to be among the diagnostic features at genus level (Stål 1872, Champion 1898, Gil-Santana et al 2013, Martin-Park et al 2012). …”

First description of the male of Volesus nigripennis Champion, 1899, with new records from Ecuador and Panama, taxonomical notes, and an updated key to the genera of Sphaeridopinae (Hemiptera, Reduviidae)

“…Further records of Reduviidae from Ecuador and Panama were provided by Maldonado (1990) and in papers describing or reviewing different taxa of this family (e.g. Dougherty 1995, Martin-Park et al 2012, Zhang et al 2016).…”
