Propetes triquetra (Fabricius, 1803)


Propetes triquetra (Fabricius, 1803) 

( Figs 5–8View FIGURES 1 – 8, 16–26View FIGURES 9 – 18View FIGURES 19 – 26)

Length (mm). Males 9.4 – 15.0. Females 15.0 – 18.0.

External morphology. External morphological characters as in generic description ( Young 1968: 204‒205).

Male genitalia. Male genitalia characters as in redescriptions and illustrations by Schröder (1957) and Young (1968) ( Takiya et al. 2006).

Female genitalia. Abdominal sternite VII, in ventral view, subrectangular, approximately 1.5 times wider than long; lateral margins parallel; ventral surface without setae; posterior margin with prominent broad subquadrate median lobe, slightly longer than lateral lobes ( Fig. 19View FIGURES 19 – 26). Sternite VIII with two sclerotized regions ( Fig. 20View FIGURES 19 – 26). Pygofer, in lateral view, well produced posteriorly; lobe surface with few setae on ventral and posterior margins; posterior margin rounded ( Fig. 21View FIGURES 19 – 26). First valvifer, in lateral view, with anterior margin obliquely rectilinear; posterior margins almost acute ( Fig. 22View FIGURES 19 – 26). First valvula, in lateral view, with dorsal sculptured area present on apical three-fifths, formed mostly by scale-like processes arranged in oblique lines; ventral sculptured area restricted to apical portion, formed mostly by scale-like processes; preapical region with ventral margin with small denticles; apex acute ( Figs 22‒23View FIGURES 19 – 26). Second valvifer, in lateral view, higher than wide; group of setae present on median portion near posterior margin ( Fig. 25View FIGURES 19 – 26). Second valvula, in lateral view, regularly broadened beyond basal curvature; dorsal margin with about 45 separated teeth, each approximately subquadrate, becoming gradually smaller, angulate, and more closed spaced towards apex; preapical region with ventral margin with distinct protuberance; apices narrowly rounded ( Figs 25‒26View FIGURES 19 – 26). Third valvula, in lateral view, with basal half narrow and apical half distinctly expanded; apex rounded ( Fig. 24View FIGURES 19 – 26).

Notes. The description and photographs provided herein for the female of P. triquetra  are based on the association of males and females from Santo Antonio do Tauá, Pará State, Brazil. This is the only locality represented among studied material where both males and females of Amazonian Propetes  were collected. This particular female of P. triquetra  (as well as, other females listed in the examined material below from Eastern Amazonia) agree with the external morphology of the holotype of P. compressa  and lectotype of P. trimaculata  , including the shape of the abdominal sternite VII. Dissections of the genitalia of these female specimens did not reveal any diagnostic difference to separate them in different species and, for this reason, the female genitalia of these primary types were spared from dissection. So it is most probable that no morphological differences are found in females of P. triquetra  and P. sabakibara  and some female specimens treated herein as P. triquetra  could in fact be P. sakakibara  . Nevertheless, until more Amazonian Propetes  females are available for study and show reliable diagnostic characters to differentiate these two species, we prefer to consider all available females from Eastern Amazonia (Pará and Mato Grosso states, see discussion below on geographic distribution), including primary female types of P. compressa  and P. trimaculata  , as conspecific with P. triquetra  males. Thus, under the Principle of Priority of the International Code of Zoological Nomenclature (ICZN 1999), the valid name for this species is P. triquetra  .
