Stenogobius laterisquamatus (Weber, 1907) View in CoL

Twenty-seven specimens were analysed, including type specimens ( ZMA116477 View Materials ), from Papua ( Indonesia) and PNG .

The species was described on the base of two specimens from a location in Northern Papua, Moso River , tributary of Tami River by de Beaufort and Weber. The type locality is close to the border between Indonesia and PNG. The main morphomeristic characters are given below .

D VI-I, 10; A I-10; C 13-15; P 15-17 (mainly 16); PD 17-26; TRB 10-14; TRF 15-20; LS 50-64; ZZ caudal peduncle 9-11; ZZ D2 base 9-11; head length between 24 to 26 (in % of SL); preanal length 53-58 (in % of SL) (except for one specimen with 35); BDL 16-25 (in % of SL); BDM 15-26 (in % of SL); caudal peduncle length 8-17 (in % of SL); HD1 18-30 (female) to 25-35 (male) (in % of SL); jaw length 6-9 (in % of SL); anal length 33-47 (in % of SL); second dorsal 33-42 (except for one specimen with 63) (female) to 41-53

(male) (in % of SL); caudal peduncle depth 9-12 (in % of SL); space inter D1-D2 7-10 (female) to 6-10 (male) (in % of SL); eye diameter 4-7 (in % of SL); interorbital distance 4-7 (in % of SL); snout length 5-9 (in % of SL); interdorsal membrane distance 1-4 (female) to 1-6 (male) (in % of SL); pelvic length 17-25 (in % of SL); pectoral length 16-23 (in % of SL). Cheek scaled, opercle scaled; central pectoral base scaled; breast and belly scaled; predorsal region fully scaled on the anterior part to the first dorsal fin; first dorsal fin with four to six spaced black marks along the first dorsal spine, a black band all along the fin base, more pronounced on the anterior part of each membrane between spines, a medial black band from the first spine to the posterior part of the fin ( Fig. 5 View Figure 5 ). Pores and papillae are presented in Fig. 6 View Figure 6 .

Because of the restricted number of male specimens studied here ( 7 specimens), sexual dimorphism for this species was not analysed.
