Tetragonoderus subfasciatus Putzeys

Fig. 2D, 3D, 4D, 5G-H, 6

Dromius subfasciatus Putzeys 1846: 376 . Type Material: LECTOTYPE (here designated), male, labeled: “ Dromius / Putz” [MNHP]. Type Area : Cumana, Venezuela.

Tetragonoderus subfasciatus ; Chaudoir 1876: 47; Csiki 1932: 1299; Blackwelder 1944: 52; Lorenz 2005: 453.

Notes about type material. In the original description, Putzeys (1846: 376) referred to 4 specimens from Cumana, Venezuela. Chaudoir (1876: 47) stated “I have the Putzeys type from Cumana ( Venezuela).” The single specimen associated with box label “ subfasciatus Putzeys Venezuela Cumana Putzeys” in the MNHP is selected and here designated as LECTOTYPE.

Recognition. Readily separated from the three species of the quadriguttatus assemblage by the markedly transverse elytral microsculpture, which renders the elytra subiridescent.

Description. See Table 1 for values for standardized body length (SBL) and ratios Hl/Hw and Pl/Pw.

Elytra. Bicolored, with mesh pattern distinctly transverse, sculpticells very wide, with few longitudinal edges (Fig. 3C and 4C).

Male genitalia. Phallus (Fig. 5G-H) in dorsal aspect slender, medial part of shaft parallel-sided, with apical portion curved to right; periostial area relatively long, more than one third length of shaft; apical area narrow, short, flat, slightly spatulate; in lateral aspect shaft slightly curved, apical area thicker apically. Endophallus, inverted, with small microtrichial field to right of midline in dorsal aspect, and partially within the periostial area.

Notes about habitat. No specific label data are available regarding possible habitat. All three specimens with collection data were taken at UV light.

Notes about variation. Only one of the three specimens in the UASM has the elytral color pattern as in Fig. 2D. The other two specimens have reduced pale markings, so that they appear more like the other “four-spotted” species of the quadriguttatus assemblage.

Geographical distribution. (Fig. 6). This species is currently known only from northern Venezuela and Panamá. One would expect it to occupy Colombia as well.
