Diagnosis. Male of this species can be distinguished from other Adalmus species by the following characters: body size longer than 2.2 mm; antennomere I approximately 2.8 times as long as II; rostrum narrow (HW: RW = 52: 20); protrochanter with small spine ( Fig. 8L View Fig ), mesotrochanter weakly convex ( Fig. 8M View Fig ), metatrochanter with distinct curved spine ( Fig. 8N View Fig ); left paramere thick, S-shaped, with thin, short, and curved spine, right paramere curved, apex bifurcated; apex of median lobe curved and serrate ( Figs 8O, P View Fig ).
Description. BL 2.40 mm (FBL 1.65 mm); body blackish- -brown, antenna, and legs reddish-brown, maxillary palpus and tarsi yellowish-brown; body pubescent.
Head slightly broader than long (HL: HW = 42: 52), widest at anterior 2/3, eyes convex, impression between ridge of antennal tubercles deep, ridge of antennal tubercles parallel; apex of rostrum weakly projecting, clypeus barely visible in dorsal view, temple as long as gena, gena nude in dorsal view; antennal length 0.97 mm, antennomere I approximately three times as long as II, antennomere II longer and broader than III–VIII, antennomeres III–V of similar length, VI and VIII of similar length, IX and X of similar length, antennomeres IX–XI forming indistinct club, XI approximately 1.7 times as long as broad.
Thorax. Prothorax slightly broader than head (HW: PW = 41: 44), subhexagonal (PL: PW = 47: 44), broadest at anterior 2/5, narrowest at base.
Elytra slightly broader than long (EL: EW = 65: 74), with sutural striae, weak impression at basal elytral foveae, subhumeral foveae present, not visible in dorsal view.
Legs. Protrochanter with small spine; profemur weakly rugose on ventral side; mesotrochanter weakly convex, metatrochanter with distinct curved spine; tibiae and femora of similar length, moderately long.
Aedeagus asymmetric, 0.37 mm long, with diaphragm and basal stem; parameres asymmetric, left paramere thick, S-shaped, with thin, short, and curved spine, right paramere curved, apex bifurcated; apex of median lobe curved and serrate.
Sexual dimorphism. Female unknown.
Etymology. The specific epithet is a noun in the nominative case, a combination of the Latin words serratus (ʻserrateʼ, masculine) and lumbus (ʻgenitaliaʼ, masculine), and refers to the serrate apex of the median lobe.
Distribution. New Zealand (South Island: WD; Fig. 10 View Fig ).
