Diagnosis. Phrynidius poriferus sp. nov. differs from P. diminutus Gutiérrez, Toledo & Noguera, 2020 by the antennomere III longer than the scape (shorter than the scape in P. diminutus ), eye lobes closer to each other (wellseparated in P. diminutus ), and erect elytral setae distinctly more abundant (distinct only on posterior region of elytra in P. diminutus ), sides of the prothorax more rounded (sub-straight in P. diminutus ), elytra more widened centrally (narrower in P. diminutus ), and elytra with short and erect setae throughout (only apically in P. diminutus ). It differs from P. skillmani sp. nov. by the prothorax shorter and more rounded laterally (longer and slightly rounded laterally in P. skillmani sp. nov.), scape with distinct squamiform setae interspersed and not slightly widened apically (with a few very short yellowish-brown squamiform setae and slightly widened apically in P. skillmani sp. nov.), and antennomere III 0.6 times longer than antennomere IV (twice length of IV in P. skillmani sp. nov.); from P obrieni sp. nov. and P. wibmeri sp. nov., especially by the prothorax proportionally smaller (proportionally larger in these two species), erect setae on elytra more abundant (sparser in these two species), and lower eye lobes slightly longer than wide (1.18 times) and without ommatidia between them (distinctly longer than wide (1.8 times in P. obrieni sp. nov. and 1.35 times in P. wibmeri sp. nov.) and with ommatidium between them in these two species); and from P. guatemalensis sp. nov. by the prothorax distinctly rounded laterally (more elongated in P. guatemalensis sp. nov.), erect setae on elytra more abundant (present only on posterior region of elytra in P. guatemalensis sp. nov.), and pronotum and elytra coarsely and more abundantly punctate (punctures finer and sparser in P. guatemalensis sp. nov.).

Description. Holotype Female. Integument mostly black; palpomeres and tarsi reddish brown; prosternal process, mesoventral process, and trochanters dark reddish brown; femora and tibiae mostly dark brown, except dark-reddish brown apex of tibiae.

Head. Frons coarsely, somewhat rugose-punctate; with minute yellowish-brown pubescence not obscuring integument, slightly denser close to clypeus, and short, erect, thick, somewhat spatulate yellowish-brown setae interspersed. Antennal tubercles sparsely, coarsely punctate, punctures distinctly finer than on frons, except smooth apex; with abundant yellowish-brown pubescence not obscuring integument, and short, thick, erect setae as on frons on frontal base, shorter, more abundant and more decumbent toward apex. Vertex sparsely, coarsely punctate, with yellowish-white pubescence partially obscuring integument between antennal tubercles and laterally, and sparse, short, erect, spatulate yellowish-brown setae interspersed, glabrous centrally (pubescence probably lost). Area behind eyes and genae somewhat abundantly, coarsely punctate; with abundant, very short, slightly bristly yellowish-white pubescence partially obscuring integument; genae 3.15 times longer than length of lower eye lobe. Postclypeus with sculpturing and pubescence as on frons posteriorly, smooth, not pubescent, with sparse, long, reddish-brown setae close to anteclypeus. Anteclypeus very narrow. Labrum abundantly, finely punctate on wide posterior area, nearly smooth anteriorly; with both short and long, erect reddish-brown setae on posterior 2/3, and dense fringe of golden setae on anterior third. Eye lobes without ommatidia between lobes; distance between upper eye lobes 0.54 times distance between outer margins of eyes; in frontal view, distance between lower eye lobes 0.72 times distance between outer margins of eyes; lower eye lobes slightly longer than wide (1.18 times). Antennae 1.2 times elytral length, slightly surpassing posterior third of elytra. Scape slightly widened from basal quarter; with abundant, minute yellowish-white pubescence not obscuring integument, and short, decumbent, squamiform, both white and yellowish setae interspersed, more abundant on posterior third of dorsal surface and sides, and short, erect yellowish-brown setae interspersed dorsally. Pedicel nearly glabrous on basal half, with dense grayish-white pubescence obscuring integument on posterior half. Antennomere III slightly arched, with abundant grayish-white pubescence on basal third, yellowish brown on remaining surface, with decumbent, sparse, white squamiform and short, erect, sparse yellowish-brown setae interspersed dorsally. Antennomeres IV–IX with abundant yellowish-white pubescence not obscuring integument (whiter depending on light intensity); antennomeres X–XI with dense whitish pubescence partially obscuring integument. Antennal formula (ratio) based on length of antennomere III: scape = 0.88; pedicel = 0.15; IV = 0.60; V = 0.27; VI = 0.24; VII = 0.24; VIII = 0.21; IX = 0.21; X = 0.19; XI = 0.28.

Thorax. Prothorax wider than long; sides uniformly rounded. Pronotum coarsely, abundantly punctate; with distinct, but not strongly elevated, longitudinal gibbosity centrally, from slightly before middle to posterior quarter, and subcircular, slightly elevated gibbosity on each side of central gibbosity; with minute yellowish-brown pubescence not obscuring integument, and short, erect, spatulate light reddish-brown setae interspersed, shorter, more decumbent and yellowish white on lateral gibbosities. Sides of prothorax with sculpturing and pubescence as on pronotum, and sparse, short, decumbent, squamiform yellowish-white setae interspersed. Prosternum abundantly, coarsely punctate; with minute yellowish-brown pubescence laterally, and minute yellowish-white setae on wide central area, both not obscuring integument. Prosternal process with a few coarse punctures; sides of anterior 4/5 sinuous; narrowest area, located near base, 0.33 times procoxal width; with yellowish pubescence not obscuring integument centrally, sparser, shorter yellowish-white pubescence on remaining surface. Sides of mesoventrite, mesanepisternum, and mesepimeron coarsely punctate; central area of mesoventrite smooth; sides of mesoventrite and superior region of mesanepisternum with dense light yellowish-brown pubescence obscuring integument; remaining surface of mesoventrite and mesanepisternum and entire mesepimeron with sparse, minute yellowish-white setae (more abundant on central area of mesoventrite). Mesoventral process slightly widened from middle; apex 0.45 times mesocoxal width; with yellowish-brown pubescence not obscuring integument. Metaventrite coarsely, sparsely punctate; with minute yellowish-brown pubescence not obscuring integument, and sparse, short, decumbent, squamiform yellowish-white setae interspersed. Elytra. Sub-ovoid; coarsely, deeply, abundantly punctate; with irregular, slightly elevated, somewhat vermicular gibbosity on basal 2/3, and moderately elevated tubercles with blunt apex on posterior third; with sparse, minute yellowish-white pubescence, denser on irregular spots, and moderately abundant, long, erect, spatulate yellowish-brown setae interspersed throughout. Legs. Femora with abundant yellowish pubescence not obscuring integument, long, erect brownish spatulate setae interspersed dorsally, decumbent squamiform whitish setae interspersed laterally, and short, erect brownish setae on sides of ventral surface. Tibiae with abundant yellowish pubescence not obscuring integument, except glabrous narrow apex of dorsal surface and longitudinal band on posterior quarter of sides of protibia, dense, bristly yellowish-brown pubescence on ventral surface close to apex, dense, short, erect yellowish-brown setae on dorsal sulcus of mesotibiae, and dense fringe of yellowish-brown setae on apical margin of all tibiae; dorsal surface with long, erect, spatulate brownish setae interspersed and sides with a few decumbent squamiform whitish setae interspersed.

Abdomen. Ventrites with minute, somewhat abundant yellowish-white setae not obscuring integument, sparser on ventrites 3 and 4, and decumbent, squamiform whitish setae interspersed on ventrites 1, 2, and 5. Posterior third of ventrite 5 obliquely inclined toward apex.

Male. Similar to female, differing by the antennae slightly longer, 1.5 times elytral length.

Chromatic variation. The integument of some paratypes is considerably lighter, mostly brown, than that of the holotype. This chromatic variation is relatively common in species of Phrynidius .

Dimensions in mm (holotype female/ paratype male/ paratype female). Total length, 4.80/4.90/6.10; prothoracic length, 1.25/1.50/1.70; anterior prothoracic width, 1.30/1.35/1.70; posterior prothoracic width, 1.40/1.55/1.95; maximum prothoracic width, 1.60/1.70/2.15; humeral width, 1.55/1.70/2.10; elytral length, 3.10/3.00/3.85. Note: only one paratype of each sex was measured.

Etymology. Latin, “poriferus” (pore-carrying); allusive to the pronotal and elytral punctures.
