Type material.

Holotype: male, Panama: Veraguas Province: Cuenca 097; Santa Fe District; Santa Fe NP; Río Piedra de Moler; PSPSCB-PNSF-C097-2017-012; 8.56553°N, 81.18817°W; 340 m a.s.l.; UV light trap; A. Cornejo, T. Ríos, E. Álvarez, C. Nieto, leg.; 20.iv.2017; MIUP-003-T-2023 (in alcohol).

Diagnosis.

This species is similar to B. espinosa Harris, Holzenthal & Flint, from Brazil, Ecuador, French Guiana, and Venezuela, both having prominent stout, spine-like setae arising from the sides of segment VIII. Bredinia paraespinosa sp. nov. differs from this species in the elongate anterior apodemes from the lobes of segment VIII and the structure of the phallus which has the sides bearing an elongate apical spine.

Description.

Male. Total length 1.5 mm, 17 antennal segments, wings and body brown in alcohol. G enitalia. Abdominal segment VII annular, lacking a ventromesal process. Segment VIII annular, lateral lobe bearing prominent, spinelike setae, anterior margin produced into elongate apodeme, projecting into segment VI; in dorsal view with central plate which appears to be part of the lateral lobe; in ventral view, deeply incised mesally, lateral lobes with elongate posterior spines. Segment IX narrowing ventrally; in dorsal view tapering distally to emarginated apex; ventrally reduced and membraneous. Segment X triangular in lateral view, thin with posterior emargination in dorsal and ventral views. Inferior appendage circular in lateral view, bearing pair of elongate, stout setae distally; in ventral view spatulate, inner margin diverging, with hooklike sclerite basally. Subgenital plate thin in lateral view, bifid apically; in dorsal and ventral views a narrow band, with extended lateral margins. Phallus tubular, posteriorly widening with lateral apices narrowed to acute spine, mesally diverging with ejaculatory duct protruding; in lateral view wide basally, tapering distally to upturned apex.

Distribution.

Panama.

Etymology.

This species name Bredinia paraespinosa (spiny-like) derives from Spanish, referring to its spiny resemblance to Bredinia espinosa . The name is a noun in the nominative singular standing in apposition.
