(Figs 5, 6)
Material examined. Holotype (♂): Indonesia, E Kalimantan, ca. 55 km W of Balikpapan, PT Fajar Surya Swadaya [area], 01 ° 183S, 116 ° 21.0’E, 100 m. J. Hájek, J. Schneider & P. Votruba leg. 24–25+ 29.xi.2011; border of Acacia mangium plantation and primary rainforest stream and waterfall, puddles, individual collecting + light trap; Collection National Museum, Praha, Czech Republic (NMPC).
Diagnosis. Recognized by its small body (less than 3.0 mm); vertex and frons deeply punctate (Figs 5A, B); pronotum covered with very short, fine, sparse, reclining setae (Figs 5A, B); pronotal collar absent in dorsal view (Figs 5A, B); pronotal calli flattened (Fig. 5A, B); hemelytron entirely fuscous (Fig. 5A); endosoma with long, pointed sclerite originating from base (Fig. 6B).
Description. Male: Macropterous, oval, small (Figs 5A, B). Dorsum entirely fuscous, shiny, covered with very short, fine, simple, sparse, reclining setae (Figs 5A, B). Head fuscous; vertex and frons deeply punctate, covered with very short, fine, sparse, reclining setae; remainder of head rugose, covered with relatively long, sparse setae (Figs 5A, B, D); antennomere I golden (Fig. 5A); remaining antennomeres missing in the examined specimen; labium yellow with tinged with dark brown reaching abdominal segments VI–VII. Pronotal collar absent in dorsal view; calli flattened; posterior margin weakly sinuate nearly straight (Figs 5A, B). Scutellum flattened (Figs 5A, B). Thoracic pleura. Uniformly fuscous, distinctly punctate, covered with sparse, reclining setae (Fig. 5C). Hemelytron distinctly punctate covered with very short, fine, sparse, reclining setae (Figs 5A, B). Foreleg golden, remaining legs missing in the examined specimen; tarsomere I shorter than tarsomeres II and III. Male genitalia. Aedeagus with theca moderately sclerotized (Fig. 6A); ductus seminis long and thin, its distal part inside endosoma sclerotized, relatively short; endosoma with long, weakly arcuate, sharply pointed originating basally and terminating apically spiculum, its basis weakly broadened (Fig. 6B). Parameres typical of Rhinocylapus complex: left paramere distinctly rounded, with short, rounded outgrowth on outer side apically, right paramere flattened, lateral margins nearly parallel-sided (Wolski 2010; Namyatova & Cassis 2019; Tyts et al. 2022). Left paramere: rounded apical outgrowth relatively long; sensory lobe with hook-shaped process (Figs 6C–E). Right paramere (left lateral view): apical part of paramere body rounded, apical process short, rounded (Fig. 6F).
Female. Unknown.
Measurements: See Table 1.
Etymology. The specific epithet is taken from the Latin “parvus, -a, -um”, meaning small and refers to the small size of this species.
Distribution. Indonesia (East Kalimantan) (Fig. 12).
Biology. Unknown.
Remarks. This species is most similar to P. aquilonius, P. austellus, and P. kerzhneri in sharing the hemelytron entirely fuscous (Fig. 5A) (Namyatova & Cassis 2019: fig. 4) and head deeply and densely punctate (Figs 5A, B) (Namyatova & Cassis, 2019: figs 10B, C). It can, however, be easily distinguished by its small body and lack of the pronotal collar in dorsal view (Figs 5A, B).
